Description

A restart method and terminal in recovery mode upgrade process

This application claims the priority of the Chinese patent application with the application number 202110836801.1 and the application title "A restart method and terminal during recovery mode upgrade" submitted to the China Patent Office on July 23, 2021, the entire content of which is by reference incorporated in this application.

technical field

The present application relates to the technical field of terminals, in particular to a restart method and a terminal during recovery mode upgrade.

Background technique

Recovery mode (recovery mode) is an Android (Android) phone backup function, which refers to a mode that can modify the internal data or system of an Android phone (similar to windows PE or DOS). In this mode, the existing system can be backed up or upgraded, and the factory settings can also be restored here.

Because during the upgrade process of Recovery mode, the power button needs to be used to confirm the selection, so the power button is not shielded. When it is detected that the power button has been pressed for a long time but the long press time has not reached the restart/shutdown time requirement, a text prompt will be given. However, when it is detected that the power button is pressed for a long time and the long press time reaches the restart/shutdown time requirement, it will cause the mobile phone to shut down. Therefore, during the upgrade process of Recovery mode, there may be accidental touches that cause the mobile phone to shut down, that is, the mobile phone shuts down caused by mistakenly pressing the power button for a long time. In addition, because the content of the partition corresponding to the image in the upgrade package will be overwritten during the upgrade process, some partitions may be erased first, and then the image will be burned. If the mobile phone is forced to restart during the recovery mode upgrade process, because the mobile phone has not been upgraded, it will re-enter the upgrade next time, but because the previous upgrade was interrupted, a key partition may be damaged, resulting in the failure of the phone to boot to the main The system and recovery mode make the phone unusable.

Contents of the invention

The embodiment of the present application provides a method and terminal for restarting during the upgrading process of the recovery mode, which can reduce the restarting caused by the user's mistaken touch during the upgrading process of the recovery mode, thereby reducing the probability that the mobile phone cannot be used.

The following introduces the present application from different aspects, and it should be understood that the implementation manners and beneficial effects of the following different aspects can refer to each other.

In the first aspect, the present application provides a restart method in the recovery mode upgrade process, the method includes: the terminal searches for the system version update package under the main system and downloads it, and after the download is completed, detects whether the user performs a preset operation (such as clicking restart control); if it is detected that the user performs a preset operation, the terminal will call the restart command under the main system and add the restart parameter recovery to restart; when the terminal restarts to lk (little kernel/small operating system (little kernel, lk for short) )) phase, detect whether to enter the recovery mode; if it is detected that the terminal enters the recovery mode during the restart process, the terminal will configure the forced shutdown button to press and hold the power button and the volume button at the same time for a preset time. Wherein, the volume key here can be either a volume up key or a volume down key. The preset time here can be 10s or 15s, etc.

It can be seen that by configuring the forced restart function/forced shutdown button as a long press of the power button and volume button for a period of time after the detection of entering the recovery mode, this solution can not only reduce the restart caused by the user's accidental touch during the recovery mode upgrade process (this is Because the probability of the user accidentally touching the combination key at the same time is low), thereby reducing the probability of the mobile phone being unusable, it can also solve the problem of not being able to directly exit the recovery mode in abnormal scenarios (such as a crash, the mobile phone cannot operate normally, etc.) (this is because this solution The forced restart/shutdown function is still retained in recovery mode).

In combination with the first aspect, in a possible implementation, the terminal configures the forced shutdown button to simultaneously press and hold the power button and the volume button for a preset time, including: the terminal calls a power management integrated circuit (Power Management IC, pmic) to set the register The value is set to 0x01, so that the forced shutdown key is set as a combination key (such as the power key and the volume up key, or the power key and the volume down key, or the volume up key and the volume down key), that is to say, the forced restart trigger mode is set Press and hold the key combination at the same time.

Optionally, before the terminal enters the recovery mode, the forced shutdown button is the power button. That is to say, when the terminal starts to the lk stage, it will call pmic to set the register value to 0x00; when the terminal (in the lk stage) determines to enter the recovery mode, it will call pmic again to set the register value to 0x01 (or set the register value to 0x01). value changed from 0x00 to 0x01).

It can be seen that this solution changes the corresponding relationship between the forced restart function and the physical button by calling the pmic to change the register value, which is conducive to reducing false touches and changing back to the original configuration after exiting the recovery mode.

In combination with the first aspect, in a possible implementation, the terminal detects whether to enter the recovery mode during the restart process, including: the terminal detects whether there is a flag bit boot-recovery in the misc partition during the restart process; if the terminal detects the misc partition If there is a flag bit boot-recovery in the terminal, the terminal determines to enter the recovery mode during the restart process. If the flag bit boot-recovery does not exist in the misc partition, it means that the recovery mode has not been entered.

Because the misc partition is empty during normal startup, the upgrade information of the misc partition will be written only when entering the recovery mode, mainly into the flag bit boot-recovery. Therefore, this solution can accurately determine whether the terminal enters the recovery mode by detecting whether the flag bit boot-recovery exists in the misc partition.

With reference to the first aspect, in a possible implementation manner, the method further includes: after the terminal enters the recovery mode, monitor the physical buttons of the terminal through a thread, where the physical buttons include a power button, a volume up button, and a volume down button one or more; when it is detected that the power button is long pressed, the terminal monitors whether the volume button is long pressed at the same time; when it is detected that the power button is long pressed and the volume button is not If the preset time is exceeded; if the power button is pressed for longer than the preset time, the terminal will output a first prompt message, which is used to prompt the risk of forced restart and the correct forced shutdown method. Wherein, the way for the terminal to output the first prompt information may be voice, text, ringing, vibration and other ways.

Optionally, the terminal outputs the first prompt information, including: the terminal calls the display interface to display the first prompt information at a preset position on the terminal screen (such as the original upgrade interface), and the input parameters of the display interface include the first prompt information and preset positions. Wherein, the preset position is the displayed position coordinates.

It can be seen that after long pressing the power button for more than the preset time, this solution will output the corresponding prompt information, prompting the risk of forced restart and the correct way of forced shutdown. On the one hand, it is beneficial for users to forcibly shut down in abnormal scenarios (such as crashes, mobile phones cannot operate normally, etc.).

With reference to the first aspect, in a possible implementation manner, the method further includes: if it is detected that a long press of the power button and a long press of the volume key are detected at the same time, the terminal monitors whether the time of the simultaneous long press exceeds the above preset time; If the time of the long press does not exceed the preset time, the terminal outputs second prompt information, and the second indication information is used to prompt the risk of forced restart. Wherein, the manner in which the terminal outputs the second prompt information may be voice, text, ringing, vibration, and the like.

Optionally, the terminal outputs the second prompt information, including: the terminal calls the display interface to display the second prompt information at a preset position on the terminal screen (such as the original upgrade interface), and the input parameters of the display interface include the second prompt information and preset positions. Wherein, the preset position is the displayed position coordinates.

It can be seen that in this solution, when the power button and the volume button are pressed and held at the same time, and the time of pressing and holding the button at the same time does not exceed the preset time, a corresponding prompt message is output to prompt the risk of forced restart, so as to inform the harm of forced restart again and reduce the user's time spent on the computer. Misjudgment without knowing it.

With reference to the first aspect, in a possible implementation manner, the method further includes: after the terminal exits the recovery mode, the terminal calls the power management integrated circuit to set the register value to 0x00 during the restart process.

It can be seen that in this solution, after exiting the recovery mode, the forced shutdown button is restored to the original long-pressed power button, so as to support the functions and user operations of the terminal in the normal mode.

In the second aspect, the embodiment of the present application provides a terminal, and the terminal includes a unit for performing the restart method in the recovery mode upgrade process provided by the above-mentioned first aspect and/or any possible implementation manner of the first aspect and/or modules, so the beneficial effects (or advantages) of the restart method in the recovery mode upgrade process provided by the first aspect can also be realized.

In a third aspect, the present application provides a terminal, including a processor and a memory, wherein the memory is used to store a computer program, the computer program includes program instructions, and when the processor runs the program instructions, the terminal is made to execute the above-mentioned On the one hand, it provides a restart method during the recovery mode upgrade process.

In a fourth aspect, the embodiments of the present application provide a computer-readable storage medium for storing computer program instructions used by the first electronic device, including the program for executing the above-mentioned first aspect.

In a fifth aspect, the present application provides a computer program product containing instructions, which when run on a computer, causes the computer to execute the method for restarting in the recovery mode upgrade process described in the first aspect above.

Implementing the embodiment of the present application can reduce the restart caused by the user's mistaken touch during the recovery mode upgrade process, thereby reducing the probability that the mobile phone cannot be used.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing, etc.

2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, and a sensor driver.

The embodiment of the present application provides a restart method during the recovery mode upgrade process. By changing the corresponding relationship between the forced restart function and the physical button during the recovery mode upgrade process, the restart caused by the user's mistaken touch during the recovery mode upgrade process is reduced, thereby reducing The possibility that the mobile phone cannot be used can also solve the problem of not being able to directly exit the recovery mode in abnormal scenarios.

Before introducing the technical solution of the present application, the recovery partition and the misc partition of the Android system involved in the embodiment of the present application are briefly described. Among them, the recovery partition can be understood as an alternative boot partition, allowing the device to boot to a recovery console to perform preset recovery and maintenance operations. The misc partition contains system settings in the form of ON/OFF switches. These settings can include CID (Carrier or Region ID), USB configuration and some hardware settings, etc. The misc partition is an important partition. If it is damaged or lost, some device functions will not work properly.

Referring to FIG. 4 , FIG. 4 is a schematic flowchart of a restart method during an upgrade in recovery mode provided by an embodiment of the present application. Fig. 4 shows the internal data processing process of the terminal. As shown in Figure 4, the restart method in the recovery mode upgrade process provided by the embodiment of the present application includes but is not limited to the following steps:

S1. If it is detected that the terminal enters the recovery mode, the terminal sets the trigger mode of the forced restart of the terminal to long press the power button and the volume button at the same time.

Optionally, the terminal in this embodiment of the present application may be a mobile phone. The user can enter the recovery mode through one or more operations on the terminal. In an example, the terminal can detect whether the system version has been updated under the main system, and if there is an update, the terminal can prompt in the form of a pop-up window or a notification bar. If the user chooses to update the system version, the terminal searches for the system version update package under the main system and downloads it. After the terminal downloads the system version update package required for the upgrade, the restart control is displayed on the system version update interface. If the user clicks the restart control, the terminal will respond to the user’s click operation and call the restart command, and add the restart parameter recovery. This restart command will write the flag bit boot-recovery in the misc partition, and then the terminal will restart. At this time, the terminal enters recovery model. In short, the terminal downloads the upgrade package under the main system, and when it needs to be upgraded after downloading the upgrade package, call the restart command, add the restart parameter recovery, write the flag boot-recovery in the misc partition, and then restart to enter the recovery mode Do a HOTA upgrade. In another example, after the terminal is powered off, physical keys (such as volume keys and power (power) keys) of the terminal and whether a charger/PC-USB is connected will still be read. When the terminal detects that the volume up (+)/down (-) button and the power button are pressed and held at the same time and the charger/PC-USB is connected, the terminal restarts and displays the recovery main interface or erecovery main interface, and the terminal enters recovery mode at this time. Referring to FIG. 5 , FIG. 5 is a schematic diagram of the recovery main interface and the erecovery main interface provided by the embodiment of the present application. As shown in Figure 5, the terminal needs to use the volume keys to move the cursor on the recovery main interface or the erecovery main interface, and use the power key to confirm. It should be understood that the power key and the volume key are located on the same side as shown in FIG. 5 . In actual implementation, the power key and the volume key may be located on different sides of the terminal, which is not limited in this embodiment of the present application.

It can be seen that in the recovery mode, in addition to the HOTA upgrade, there are recovery main interface, erecovery upgrade and other interfaces that use the power button. Therefore, in order to prevent accidental restart during the recovery mode upgrade process, the power button in recovery mode cannot be directly blocked, and in order to avoid abnormal scenarios, such as crashes, and the phone cannot operate normally, the method of forcing a restart through the button must also be retained.

Therefore, the terminal in the embodiment of the present application will detect whether there is a flag, such as boot-recovery, in the misc partition during the startup process (such as the lk stage). If the flag bit boot-recovery exists in the misc partition, the terminal determines to enter the recovery mode. This is because the misc partition is empty during normal startup, and the upgrade information of the misc partition will be written only when it enters the recovery mode, mainly into the flag bit boot-recovery. When it is detected that the terminal enters the recovery mode, the terminal can set the trigger mode of the forced restart of the terminal to press and hold the power button and the volume button at the same time.

It should be understood that the startup process of the terminal includes: first power on, and then the CPU starts a preloader (preloader), the preloader is used to start a small kernel/small operating system (little kernel, lk for short), lk is mainly responsible for mode selection, according to Select the mode to load the corresponding content, and then start the corresponding service through the initialization function (init) of the virtual memory disk (ramdisk). Among them, when the terminal starts to the lk stage, it will initialize the button function according to the configuration file. Taking multi-tone keying (MTK) as an example, when the terminal boots to the lk stage, call the long-press restart function setting (such as long_press_reboot_function_setting) function to set the forced restart method. If the restart-related macro configured in the configuration file is the one-key restart mode (for example, the configuration file includes the macro "CONFIG_ONEKEY_REBOOT_NORMAL_MODE=y"), the terminal calls the power management integrated circuit (Power Management IC, pmic) to set the register value to 0x00 (eg: PMIC_RG_PWRKEY_KEY_MODE, 0x00), so as to set the power button as a forced restart button, that is to say, set the trigger mode of forced restart to long press the power button. If the restart-related macro configured in the configuration file is the two-key restart mode (for example, the configuration file includes the macro "CONFIG_TWOKEY_REBOOT_NORMAL_MODE=y"), the terminal calls pmic to set the register value to 0x01 (such as: PMIC_RG_PWRKEY_KEY_MODE, 0x01), thereby setting The forced restart key is set as a combination key, that is to say, the trigger mode of the forced restart is set to press and hold the combination key at the same time. It should also be understood that the terminal will initialize key functions according to the configuration file during each startup process.

The terminal in the embodiment of the present application sets the forced restart trigger mode of the terminal to long press the power button and the volume button at the same time, including: after the terminal recognizes that it has entered the recovery mode, it calls pmic again to set the register value to 0x01, so that the combined key (For example, the power button and the volume up button, or the power button and the volume down button) are set as the forced restart button, that is to say, the forced restart trigger mode is set to long press the power button and the volume button at the same time. Wherein, before the terminal in the embodiment of the present application enters the recovery mode, the forced restart key is the power key. That is to say, when the terminal starts to the lk stage, it will call pmic to set the register value to 0x00; when the terminal (in the lk stage) determines to enter the recovery mode, it will call pmic again to set the register value to 0x01 (or set the register value to 0x01). value changed from 0x00 to 0x01).

S2. If the terminal detects that the power button has been pressed for a long time after entering the recovery mode, the terminal displays a first prompt interface. The first prompt interface includes text prompts for prompting the risk of forced restart and the correct trigger method for forced restart.

Optionally, after the terminal enters the recovery mode, it can monitor the physical keys (such as power key and volume key) of the terminal through /adopt/start thread. If the terminal detects that the power button is long pressed after entering the recovery mode, the terminal detects whether the volume button is long pressed at the same time (here refers to the volume up key or the volume down key); if the terminal detects that the volume key is not pressed at the same time, the display interface is called Display the first prompt interface. The input parameters of the display interface include displayed content (such as text, image, etc.) and displayed position coordinates. Wherein, the first prompt interface includes a text prompt, which is used to prompt the risk of forced restart and the correct triggering method of forced restart. The first prompt interface can be a brand new interface, or a corresponding text prompt can be added to the original upgrade interface. Exemplarily, the text prompt on the first prompt interface may be "updating, please do not press and hold the power button. During the upgrade process, a forced restart will cause abnormality of the device. If you need to force shutdown, please press and hold the power button and volume up at the same time. /down key".

Optionally, if the terminal detects a long press of the power button after entering the recovery mode and the long press time exceeds the first time threshold, the terminal calls the display interface to display the first prompt interface. For example, the first time threshold is 10 seconds (s). In this way, if the user presses the power button for less than the preset time threshold, the display interface may not be invoked to display the first prompt interface, thereby saving power consumption.

For example, refer to FIG. 6A , which is a schematic diagram of a first prompt interface provided by an embodiment of the present application. As shown in FIG. 6A , after the terminal enters the recovery mode, the user presses and holds the power button for more than 10 seconds, and the terminal invokes the display interface to display a first prompt interface 601 . The first prompting interface 601 is a brand-new interface, and its text prompting can be positioned at the middle position of the interface, and adopts methods such as thickening, the font of different colors to highlight; Optionally, a The return control 602 is used to return to the original upgrade interface (that is, the original HOTA upgrade interface). Referring to FIG. 6B , FIG. 6B is another schematic diagram of the first prompt interface provided by the embodiment of the present application. As shown in FIG. 6B, after the terminal enters the recovery mode, the user presses and holds the power button for more than 10 seconds, and the terminal invokes the display interface to display the first prompt interface 601. The first prompt interface 601 is to add corresponding text prompts on the original HOTA upgrade interface. The text prompts can be located at the top of the original HOTA upgrade interface, and can also be highlighted in bold or different-colored fonts.

S3, if the terminal detects that the power button and the volume button are pressed and held at the same time after entering the recovery mode and the time of the long press does not exceed the second time threshold, the terminal displays a second prompt interface, which includes a text prompt, and uses To warn of the risk of a forced restart.

Optionally, after the terminal enters the recovery mode, it monitors the physical buttons (such as the power button and the volume button) of the terminal through /adopting/starting the thread, so if the terminal detects that the power button and the volume button are pressed and held at the same time after entering the recovery mode /down key, and the long-pressed time does not exceed the second time threshold, the display interface is called to display the second prompt interface. The input parameters of the display interface include displayed content (such as text, image, etc.) and displayed position coordinates. Wherein, the second prompt interface includes a text prompt for prompting the risk of forced restart. The second prompt interface can be a brand new interface, or a corresponding text prompt can be added to the original upgrade interface. Wherein, the second time threshold may be 10s, 15s and so on. It should be understood that the second prompt interface is similar to the above-mentioned first prompt interface, except that the input parameters of the display interfaces are different. Exemplarily, the text prompt on the second prompt interface may be "updating, long pressing the power key and the volume up/down key at the same time will force shutdown, causing the device to be abnormal".

Optionally, when the terminal detects that the power button and the volume button are pressed and held at the same time, a timer can be started. When the time of the timer exceeds the third time threshold but does not exceed the second time threshold, the terminal may call the display interface to display the second prompt interface. This can reduce the complexity and power consumption of the terminal. Wherein, the third time threshold is smaller than the second time threshold, for example, the third time threshold is 3 seconds, and the second time threshold is 10 seconds.

S4. After the terminal enters the recovery mode and detects that the time for pressing and holding the power button and the volume button at the same time exceeds the second time threshold, the terminal is forced to shut down.

Optionally, after the terminal enters the recovery mode, it monitors the physical buttons (such as the power button and the volume button) of the terminal through /adopting/starting the thread, so if the terminal detects that the power button and the volume button are pressed and held at the same time after entering the recovery mode / down key, and the time of long pressing at the same time exceeds the above-mentioned second time threshold, the terminal will be forced to shut down. It should be understood that the forced shutdown of the terminal here can be understood as exiting the recovery mode. For example, refer to FIG. 7 . FIG. 7 is a schematic diagram of an interface change provided by an embodiment of the present application by simultaneously pressing and holding a power key and a volume key. As shown in FIG. 7 , after the terminal enters the recovery mode, the user simultaneously presses the power button and the volume up button for less than 10 seconds, and the terminal invokes the display interface to display a second prompt interface 701 . The second prompt interface 701 can be a brand new interface, and its text prompt can be located in the middle of the interface, and it can be highlighted by means of bold and different color fonts; optionally, the second prompt interface 701 can also A return control 702 is set for returning to the original upgrade interface (that is, the original HOTA upgrade interface). The second prompt interface 701 can also be to add corresponding text prompts on the original HOTA upgrade interface. highlight. If the user continues to press and hold the power button and the volume up button at the same time until the long-press time exceeds 10s, the terminal will be forced to shut down.

Optionally, if the terminal detects that the power button and the volume up/down button are pressed and held at the same time after entering the recovery mode, and the time of the simultaneous long press exceeds the second time threshold, the terminal can output a confirmation message to prompt the user whether to shutdown. When the user selects "Yes", the terminal will be forced to shut down, and the terminal will exit the recovery mode; when the user selects "No", the terminal will continue to upgrade, and the terminal will not exit the recovery mode.

Optionally, after the terminal exits the recovery mode and is in the process of restarting or after restarting, the forced restart trigger mode of the terminal will be set to long press the power button, that is, the terminal will re-read the configuration file for button configuration. That is to say, after the terminal enters the recovery mode, it will change the trigger mode of the forced restart of the terminal from long pressing the power button to long pressing the power button and the volume button at the same time; The terminal's original forced restart trigger method is to press and hold the power button to force restart.

It can be seen that in the embodiment of the present application, after the terminal enters the recovery mode, the corresponding relationship between the forced restart function and the physical buttons is changed, and the corresponding content is displayed according to the combination of different detected buttons and the length of time pressed, so as to prompt the user to enter the recovery mode. The risks/hazards of forced restart during the mode upgrade process, and the correct forced restart method can not only reduce the restart caused by the user's mistaken touch during the recovery mode upgrade process, thereby reducing the possibility of the phone being unusable, but also solve the problem that the phone cannot be used in abnormal scenarios. The problem of exiting recovery mode directly.
