Need to modify the absolute address of file, System.map is the address table of a storage All Files, such as/system/
Build.prop 851944-851946, refer to be stored in as unit of 4K from the beginning the 851944th and 851945 the two
Block (not including 851946)；
Step S104: using the system mirror image of winhex tool open ext4 format, the system mirror image of modification is wherein
File content, original characters length cannot be changed, for example ro.build.display.id=Z831V1.0.0B24 is changed into
Ro.build.display.id=Z831V1.0.0B2* not can increase or extend new character, because of newly addition character meeting
Lead to problems such as data overflow to lose with end mark, will lead to after device upgrade cannot be switched on；
Step S105: it after generating new system mirror image, reuses img2simg order and is converted to ext4 format
This system mirror image is packaged as a new version by sparse format, only system between this version and version before
Mirror image is different；
Step S106: since there are A.zip, a and renamed as fota-target-files.zip is just copied；
Step S107: decompressing fota-target-files.zip and deletes the content of IMAGES file and the inside,
It is that will use bootimage, recoveryimage and the systemimage mirror image wherein generated without deleting, it is any
Modification will not come into force.
Step S108: the file for needing to modify below in modification fota-target-files catalogue, such as SYSTEM/
Build.prop file modifies external version number therein, pays attention to modification front and back file attribute must with before unanimously；
Step S109: the All Files being packaged inside fota-target-files catalogue pay attention to centainly needing in fota-
Zip-ry is used under target-files catalogue
Fota-target-files_new.zip./order, r therein refer to that subdirectories at different levels are effective, the meaning of y parameter
Refer to retain and original all be flexible coupling；
Step S110: calling following order under the root of android translation and compiling environment,
sudo./build/tools/releasetools/img_from_target_files
Fota-target-files_new.zip fota_img.zip has new life in newly-generated fota_img.zip
At system.img and system.map, copy out and replace corresponding mirror image in original version, to generate new mesh
Mark version；
Step S111: originally remaking upgrade package using binding foot, and allows Android device to upgrade this version, sees after upgrading
See whether achieve the desired results；
Step S112: if necessary to bigger upgrade package, can fill in the binary data of suitable capacity size thereto,
Then upgrade packet signature once to this again using signature script, allow Android device to go to upgrade this version, filled in escalation process
The data entered can't be written in Android device；
The upgrade package of particular size is first made according to above method, then a common external T card is inserted into movement
In terminal, then by MTP copy mode etc., this upgrade package is copied on this T card, upgrade package is renamed as
Update.zip, referring initially to the version number of lower equipment before upgrading.The mobile Android device for needing to upgrade can be by being arranged mould
