Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention is made below in conjunction with attached drawing into
It is described in detail to one step, it is clear that the described embodiments are only some of the embodiments of the present invention rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
All other embodiment, shall fall within the protection scope of the present invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of method for restoring setting, this method includes：
When step 100, terminal judge to be switched on reason to enter recovery Recovery patterns, according to the solution confidential information read
Data partition is decrypted；
Step 101, the terminal are according to the data partition after the carry information carry decryption read；
After step 102, the terminal enter Recovery patterns, retain the target directory in the data partition after decryption,
And delete other catalogues；
Step 103, the terminal carry out data partition recovery processing.
In the embodiment of the present invention, when terminal judges to be switched on reason for into Recovery patterns, according to the decryption read
Data partition is decrypted in information；According to the data partition after the carry information carry decryption read；Into Recovery
After pattern, retain the target directory in the data partition after decryption, and delete other catalogues；It carries out at data partition recovery
Reason.Since the embodiment of the present invention is during Recovery patterns are entered, data partition is decrypted then carry so that
For terminal after Recovery patterns are entered, can retain needs the target directory retained after decrypting in data partition, deletes other
The catalogue retained is not needed to, carries out data partition recovery processing.This mode can also retain when carrying out factory reset
User needs the user data retained.
Since the embodiment of the present invention is encrypted in data partition, is carried out under the premise of carry, all read operations
All it is that user is returned to after decrypting, all information for being written to data partition are all to write data partition, institute after encrypting
With, the embodiment of the present invention there is no the encrypted state of change data subregion, after factory reset when first powering on not
It needs data partition to be encrypted operation, so as to which the available machine time can also be shortened.
The carry of the embodiment of the present invention refers to data partition being mounted under certain catalogue so that terminal can pass through the catalogue
The data of data partition are read out.
In specific implementation, user is by clicking " factory reset " option (as shown in Figure 2) in terminal " setting ",
Terminal can show the type for the user data that can retain to user, and then user is to type (such as Fig. 3 of the user data of appearance
It is shown) it is selected；
User is needed the directory information of data type retained to be retained in label subregion by terminal；
Wherein, label subregion is for the diag subregions of storing directory information or cache subregions；
Also, if label subregion is stored in cache subregions, then increases in cache/recovery/command files
Information reserve.dir fields；For enter recovery patterns after, will be in cache/recovery/command
The catalogue that reserve.dir fields are specified is as target directory.
Terminal determines that user needs the corresponding catalogue of data type preserved, terminal, which will mark, to be believed according to the selection of user
Breath is saved in the subregion without file system, such as diag subregions；
If label information is saved in diag subregions by terminal, during starting diag subregions, label letter is got
Cease and be filled into/proc/cmdline files in, judge whether to enter recovery patterns when restarting for terminal.
Also, all positions of diag subregions are there are default value, if being not written into new value, then what is got is silent
Recognize value, and do not include file system in diag subregions.
Since whether terminal belongs to containing label information the early stage rank of starting procedure in startup stage judge mark subregion
Section, if label information is saved to the subregion with file system, then this stage can not normally carry, reading, can lead
Terminal is caused to cause to judge by accident, so label information to be stored in the diag subregions without file system.
User can be needed the directory information of data type retained to be stored in diag subregions or cache subregions by terminal
In cache/recovery/command files in；
If target information is stored in cache subregions, can rapidly be performed to enter terminal after recovery patterns
Corresponding processing, then increase the information reserve.dir fields in cache/recovery/command files；
After entering recovery patterns as a result, terminal is by the information in cache/recovery/command files
The catalogue that reserve.dir fields are specified is as target directory.
For example, the data type that user wants to retain is related people and picture, then terminal is by the corresponding catalogue of contact person
Directory information and the directory information of the corresponding catalogue of picture are stored in label subregion.
After the completion of above-mentioned steps, terminal can also set the label information of decryption and carry needs, the mark in subregion is marked
Note information function is the data type that terminal judges user's preservation whether in need after restart, if not provided, just according to existing
Mode factory reset, if so, then according to the scheme factory reset of the embodiment of the present invention.
There are many modes of label information that setting of embodiment of the present invention decryption and carry need, different set-up modes,
The mode that terminal judges after restarting is also different, is introduced separately below.
Mode one, the mark mode using 1 and 0, such as the label information that can be needed 1 as decryption and carry, 0 makees
Not need to the label information of decryption and carry needs, such terminal is needed to read in label subregion after restarting on judgement symbol position
Numerical value be 1 or 0, if 1 label information for determining that decryption and carry need, if 0, it is determined that do not decrypt
The label information needed with carry.
Mode two using label and by the way of not marking, i.e., if user needs the data type preserved, is divided in label
The label information that setting decryption and carry need in area, if user does not need to preserve any data type, not in label point
Any information, such terminal is set to need the label letter for whether having decryption and carry needs in judge mark subregion after restarting in area
Breath, if there is, it is determined that there is the label information of decryption and carry needs, if it is not, determining without decryption and carry needs
Label information.
After label information is set up, it is into recovery patterns that terminal, which can set booting reason, and is opened again
It is dynamic.
After terminal restarting, terminal will determine whether to enter recovery patterns according to booting reason, if not
It needs to enter recovery patterns, then terminal will directly boot up action；
If necessary to enter recovery patterns, the label for whether having decryption and carry needs in terminal judge mark subregion
Information；
If there is label information, terminal reads carry information and encryption information.
If without label information, terminal is operated according to the scheme of prior art factory reset, needs logarithm
It is formatted according to subregion.
For example, during terminal restarts, terminal parsing/proc/cmdline files, according to/proc/
Label information in cmdline files obtains current booting the reason is that in order to enter Recovery patterns and determine parsing the
One RC files or the 3rd RC files.
In force, solution confidential information and carry information can be placed in the first RC files by the embodiment of the present invention, so eventually
End needs to load the solution confidential information in the first RC files of the first RC file acquisitions when needing to read solution confidential information and carry information
With carry information.
First RC files of the embodiment of the present invention and the 3rd RC used using the factory reset scheme of the prior art
File is different, is a new RC file；
Since factory reset scheme and the OTA upgrading of the prior art are required for loading same RC files, in order not to
Influence the factory reset scheme of the prior art and OTA upgradings；
The embodiment of the present invention defines a new RC file, such as init.recovery.rc, and confidential information is solved for storing
With carry information；
2nd RC files can be Init.rc, for storing the information of normal boot-strap；
3rd RC files can be Init.rc, for storing the information of prior art factory reset scheme.
Due to that could realize carry after only data partition is decrypted, so terminal is determining that decryption and carry need to
After the label information wanted, data subregion is decrypted using the solution confidential information read in the first RC files, later to profit
The carry information read in the first RC files carries out carry to the data partition after decryption.
After data partition carry is completed, terminal enters Recovery patterns.
Here enter after Recovery patterns due to having had determined label information before, it is possible to directly read label
Directory information in subregion.
Due to being provided with the label information of decryption and carry needs before terminal in subregion is marked, so the present invention is implemented
Whether example enters Recovery patterns in terminal can also label information in judge mark subregion again, specific judgment mode with
Judgment mode presented hereinbefore is identical, it is possibility to have two kinds of judgment modes, details are not described herein.
If without label information, operation can be directly formatted to data partition.
If the first RC files are init.recovery.rc files, the 3rd RC files are init.rc files, then terminal exists
Whether there is label information in judge mark subregion again after into Recovery patterns, if containing label information, then terminal
Parse init.recovery.rc files；If label information is not contained, then terminal parses init.rc files.
Optionally, terminal described will mark the catalogue stored in subregion to believe after the directory information in reading label subregion
Corresponding catalogue is ceased as target directory.
For example, user needs to retain contact person and pictorial information, then the directory information stored in label subregion just includes
The directory information of the corresponding catalogue of contact person and the directory information of the corresponding catalogue of contact person, terminal is by the two directory informations pair
The catalogue answered is as target directory.
If terminal stores directory information into cache/recovery/command files, terminal is needing to read
During directory information, directory information can be read from cache/recovery/command files.
Optionally, terminal retains all data under target directory, deletes other catalogues.
Such as terminal enter Recovery patterns after, according in cache/recovery/command files
Recovery.type information, which is determined, specifically enters whether Recovery patterns need to preserve user data；
If terminal stores directory information into cache/recovery/command files, and cache/
Contain reserve.dir in recovery/command files；
So terminal reads reserve.dir from cache/recovery/command files first, then, terminal from
The directory listing for needing to preserve is read in reserve.dir.
Specifically, terminal when performing delete operation, judge catalogue that current directory and reserve.dir preserve whether one
It causes, if unanimously, then retain；Otherwise it deletes.
For example, reserve.dir=path 1；path 2；path 3；
Terminal judges whether contain path 1 in current directory when performing delete operation；path 2；path 3；If
Have, then preserve, otherwise, delete.
After retaining target directory and deleting other catalogues or formatting system subregion, terminal can change booting reason
For normal boot-strap, then terminal restarting.
Factory reset or OTA (Over the air technology, under space are carried out after user in order to prevent
Load technology) upgrading, after other catalogues are deleted, terminal also needs to delete the label information marked in subregion or in advance
If information replaces the label information.
Different here according to the mode of label information setting, processing mode is also different：
If the 1st, using aforesaid way one, i.e., using 1 and 0 mark mode, then terminal replace the mark with presupposed information
Remember information, for example 1 is decryption and the label information of carry needs, then presupposed information is exactly 0；
If subregion that is, using label and by the way of not marking, then the 2, is marked described in terminal deletion using aforesaid way two
In the label information.
It is normal boot-strap in terminal modifications booting reason, then after terminal restarting, can also judges the reason that is switched on.
After determining booting reason for normal boot-strap, according to the carry information carry data read from the 2nd RC files
Subregion；
The terminal creates the database each applied in the data partition, and is the silent of each application configuration manufacture
Recognize parameter value.
Wherein, default parameters is mainly the database default value defined in software, for example, default ring tone, acquiescence suspend mode when
Between, the screen intensity etc. of acquiescence；
Default parameters is mainly used for：Each application can all read data when startup from database, so as to really
Recognize the action of execution, the effect of display etc.；It is operated by factory reset, software is determined when the data of database are restored to manufacture
The default value of justice, that is, reached state when dispatching from the factory.
As shown in figure 4, introduce a kind of entire flow figure of method for restoring setting provided in an embodiment of the present invention：
Step 400, terminal select user to need the data type pair retained after the instruction of factory reset is received
The directory information answered is retained in label subregion；
Step 401, terminal set solution confidential information and the label information of carry information in subregion is marked；
Step 402, terminal setting booting reason are into Recovery patterns, and are restarted；
Step 403, terminal judge whether booting reason is into Recovery patterns, if performing step 404；Otherwise
Jump out this flow；
Whether there is label information in step 404, terminal judge mark subregion, if so, then performing step 405；Otherwise, it holds
Row step 407；
Data subregion is decrypted in the solution confidential information of step 405, terminal in the label subregion read；
The carry information of step 406, terminal in the label subregion read hangs the data partition after decryption
It carries；
Step 407, terminal enter Recovery patterns；
Whether contain label information in step 408, terminal judge mark subregion, if so, then performing step 409；Otherwise,
Perform step 412；
Step 409, terminal will mark the corresponding catalogue of directory information stored in subregion as target directory；
Step 410, terminal retain target directory, and delete other catalogues；
Label information in step 411, terminal deletion label subregion, and perform step 413；
Step 412, terminal deletion all customer data, formatting system subregion；
Step 413, terminal modifications booting reason are normal boot-strap, and restart；
Step 414, terminal judge whether booting reason is normal boot-strap, if it is, performing step 415；Otherwise it jumps out
This flow；
Step 415, terminal are according to the carry information carry data partition read in the 2nd RC files；
Step 416, terminal create the database each applied in data partition, and are the silent of each application configuration manufacture
Recognize parameter value.
Wherein, since step 404 and step 408 are all whether to contain label information in judge mark subregion, specific real
Shi Zhong can only carry out step 404, can also only carry out step 408, and two steps all employ in this flow.
