Downgrade the LG Optimus 3D to Gingerbread
Leaks can be both good and bad. They give users and developers to a chance to check out what OEMs have in store for their devices. However, they can be fraught with danger, like the dreaded Atrix 2 ICS leak of 2012. Sometimes, it’s difficult to downgrade to a more stable previous release. This happened to the LG Optimus 3D, and there is now a fix.
XDA Senior Member berni987654321 released a method that helps get users safely back to Gingerbread. When flashing to ICS, it changes a few of the partitions and makes it difficult to flash back to Gingerbread. Here’s berni98765431’s explanation on how it was fixed:
Half a hour I read xbsals post the one whiches phones don’t boot
after flashing the gb bootloaders would need a special bin which nobody has
because nobody made a backup. But then I remembered my post in samnos thread about downgrading from wrong flashed ics leaks with my first 4 partitions attached.
The method involves downloading the partitions and flashing them. After that, it’s a matter of fixing the IMEI. Once that’s done, it’s possible to downgrade the device back to a stable Gingerbread ROM.
