Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under performing creative labour prerequisite, belong to the scope of protection of the invention.
The method of disclosed check system file integrality is based on mobile terminal, and mobile terminal is preferably the mobile device such as mobile phone or panel computer.As shown in Figure 1, the upgrade method of the system file of mobile terminal, the method comprises:
S101: mobile terminal receives AKU and pushes, and points out customer upgrade information;
S102: user determines whether carry out system upgrade according to upgrade information;
S103: if so, then mobile terminal downloads AKU;
S104: the system reboot of mobile terminal also switches to Recovery pattern and upgrades;
S105: system file is upgraded according to AKU.
Wherein, Recovery pattern is engineering mode, and in this mode, user can brush into new Android system file, or backs up system file or upgrade, or factory reset.
When system file is upgraded, the integrality of mobile terminal start-up check system file, as shown in Figure 2, the method for the check system file integrality that the present embodiment discloses comprises:
S201: the integrality of start-up check system file;
S202: the detection table reading original system file, and according to detection table look-up system file;
S203: if be checked through system file to be upgraded and detection table is inconsistent, then system file is imperfect, and the content inconsistent with original system file that show system files.
In S201, when system file is upgraded, the integrality of mobile terminal start-up check system file.Namely all can the integrality of start-up check system file in any one step in S101-S103.
In S202, detection table comprises size and the modification time of the All Files of original system file.Wherein, original system file is the system file that mobile terminal is arranged when dispatching from the factory, and look-up table is arranged in original system file.
Wherein, comprise according to detecting table look-up system file: whether the size of each file of this file of detection system is consistent with the size of the file detecting table correspondence;
If not, show inconsistent at system file to be upgraded and detection, enter S203;
If so, then whether the modification time of the file that the modification time of each file of detection system file is corresponding with detecting table is consistent;
If not, then system file to be upgraded is shown inconsistent with detection, enters S203.
In S203, if be checked through system file to be upgraded and detection table is inconsistent, system file stops upgrading, and to be showed system files the content inconsistent with original system file by the display screen of mobile terminal.
