The phone is on 2.3.4 version 4.5.629 and the bootloader is D0.11. I am looking to root and unlock this bootloader. I have read that I can downgrade using sbf to achieve a bootloader unlock and then I read other posts saying that is not possible. Also, root is apparently available through framaroot but when I use it, it says rooted and then SuperSU just constantly force closes. Not sure what to do, could someone point me in the correct direction?
