About Brush:
1. Clear Data
When we brush other ROM card when the general need to double clear (wipe), that is clear and all system data (contacts, SMS, call records, etc.), installed programs and data:
Clear Data -> sliding restore factory settings
Very small part of ROM may need to manually remove / system partition, so need to choose the Advanced Operations (see below, white is not recommended)
Note that the red line which must not choose two! One is the built-in sd card, one is external sd card, if formatted on what is gone!
2. Brush
Choose to restart the system after the main interface, select the Brush Pack installed, find the files you need to install sliding confirm, etc. Brush completion
Note that the red line is the best kept empty not to vote (crossed is selected)! Otherwise it could only brush official ROM or ROM I did, the other person might not bother to make the package or not to ROM package signatures!
About Silent Star Toolbox:
This is my personal development from the toolbox, currently offers six functions:
1. Get ROOT privileges
Use SuperSU 2.46 version to ROOT the phone, and the card brush SuperSU exactly the same effect, the current stable version SuperSU 2.46, it is not using the latest version of other unstable software can not be used on some ROOT privileges, you can try to empty the software data, Upgrading the software, or if not, it may be the program itself is not fully adapted to Android 5.0 system, you need to wait for them to update!
2. Remove ROOT privileges
This function is based on the brush into the script I wrote it myself, can be completely removed Option 1 ROOT privileges acquired, it can easily OTA (if your ROOT permissions are obtained using other methods, this feature does not ensure that the system can be restored to their original file! )
3. Backup wifi password
For copying a record of all the files you've landed wifi password to the built-sd card root directory (the file named wpa_supplicant.conf)
4. Clear battery information
If your cell phone battery power appears unstable, you can try to use this option
5. Official Recovery
Recovery for restoring the official version, only supports phone after merging partitions
6. About
Display some information about this Recovery of
Official OTA:
This Recovery is now officially supported individual first edition of the official OTA upgrade, now requires the system files of OTA Android 5.0 upgrade (/ system partition) file none to change, if you delete or turn over any documents, you can only re- card brush brush official full card package.
OTA ROOT privileges before the upgrade must be removed (try using my toolbox), installed over Xposed or delete files through the system of re-brush the official card of the complete card brush package.
Also use this word and Recovery backup does not back up the baseband files, it can also lead to OTA upgrade after the restore failed!
Recovery can show some of the reasons for this failure of OTA, press the middle of the key to display relevant, then what can be returned
This figure is due to a file does not match the OTA upgrade due to failure (/system/bin/install-recovery.sh), the specific need to see the front of the red lines of analysis, I am here it is because the permission is not removed due to ROOT
