Most of the concept & content if this thread is inspired by this thread, so a huge thanks to @Mnt-XDA.
INTRO / CONCEPT
Most of us know that we can flash custom roms or can root device only after UNLOCKING the bootloader from fastboot mode.
If you relock your bootloader, you will need to do a full backup-and-restore whenever you decide to unlock it again.
This mod will allow you to unlock the bootloader without wiping the userdata as oppose to fastboot oem unlock command.
================================================== ==========================
Note:
Many users having trouble to UNLOCK their device for the FIRST TIME by using this script.
Let me clarify few things for this mod.
The main purpose of this script is not UNLOCK Bootloader without wiping data.
It's main purpose is to reset tamper bit, which can not be done by any other way.
UNLOCK Bootloader without wiping data -- is another outcome of this MOD.
If you have not unlocked your device before (atleast for 1 time) by using command "fastboot -i 0x1ebf oem unlock", then the script might not work for you.
In case your device is locked and you want to install this script from custom recovery like TWRP,
it will be possible only if, you can boot temporarily using command -- fastboot -i 0x1ebf boot <custom_recovery.img>.
If this command failed, you will not be able to run the unlocker script and hence device will not be unlocked without wiping data. For me, it isn't working.
In which condition the device can be booted to custom recovery by using command -- fastboot -i 0x1ebf boot <custom_recovery.img>, is still not very clear.
Before running the command , check your device status "fastboot -i 0x1ebf oem device-info"
and report your error with the following points
1) Did you unlock your device before by any means? (or by fastboot -i 0x1ebf oem unlock) ?
2) What is the recovery already installed in your device?
3) What is the status of your device ? "fastboot -i 0x1ebf oem device-info"
4) What error message you got when tried to run command: fastboot -i 0x1ebf boot <custom_recovery.img>.
5) Steps you tried.
There are 4 possibilities of the the value set of the 2 bits (unlock bit & tamper bit)
1) Unlock Bit - FALSE , Tamper Bit - FALSE
2) Unlock Bit - FALSE , Tamper Bit - TRUE
3) Unlock Bit - TRUE, Tamper Bit - FALSE
4) Unlock Bit - TRUE, Tamper Bit - TRUE
After getting proper error report from you , we can give confirmation about, in which of the above state,
fastboot -i 0x1ebf boot <custom_recovery.img> will work and hence installing the unlocker script/mod/zip can help you to
UNLOCK your Bootloader without wiping DATA.
Kindly report your issues as I mentioned above...
Thanks
