1. SGP321 with stock 10.5.A.0.230 Locked Bootloader(unlocking instruction here
) or do it from Flashtool
To relock Bootloader once done, repeat this step.
1. Download SuperSU
2. Download and extract the boot.img from CM11
3. Installed fastboot (part of the Android SDK
So in step 1 above, does the bootloader need to be unlocked? Or does this method work with locked bootloader? I'm sorry, the wording is a little awkward and I would like to know if I need to back up my TA keys prior to attempting this method.
