Thanks.. it worked for me.. just applied it step by step. .:)
My Ray has official 4.0.4 and It’s a T-mobile (Hungary) branded phone. Can I apply this method?
The rooting and CWM process works, but getting bootlocker unlocked is the key. This process is tested on phones which aren’t locked to any carrier. I would ask you to not use this tutorial as a safeguard.
hello! i have a few questions. is it reversible or it is pernament (i mean unlocking the loader)? is this working on branded phones(i have a ST18i from tmobile)? if this method unlocks bootloader will i lose DRM files and warrantee (i guess i will)? finally i don’t wanna ICS on my phone the only thing i want to unlock the loader in order to install MIUI or Cyanogen ROMs. is it possible after this?
