LG Optimus L9 / Optimus 4G
Locked Bootloader for P769
Unfortunately, LG has decided to lock the bootloader and the only way to obtain the token is using UNLOCKABLE firmware which voids the warranty.
Easy enough? Nope....the official LG unlock method does not work on certain models shipped with Jelly Bean 4.1.2. Many users say it is hit or miss....that it takes several attepts. Others say that if too many failed attempts occur, the efuse gets blown making the device perma-locked.
Ultimately, it's your choice. If you enjoy a good challenge, by all means go for it. Honestly, I already tried several times and after thinking about it....I'm satisfied with being rooted and using Pimp my Rom to apply all the necessary tweaks.
