You can follow this thread http://forum.xda-developers.com/showthread.php?t=2179126 to go back either to ICS or JB. I personally favour returing back to ICS and make an update as soon as KDZ flash is finished with Offical LG update. It will erase all your data on internel memory.
Happy Flashing.

[Q] unbricked lg thrill

okay so i unbricked mt thrill using : [TUTORIAL] Flash BIN rom, Unbrick, Update - Optimus 3d (Service Flash software)
and it worked like a charm , i was wondering if any one out there had a att thrill back up from the states hiding somewhere ???
Lg doesnt even support this phone there is no official backup method for it

well, if you unbricked the phone, why not just flash Thriller, as is the one closest to stock, without all the bloatware from at&t?
okay thanks , now for another noob question. if i had a p925 and unbricked it using p920 , what roms would i use from now on, thrill or optimus ?

Both. They're mostly interchangeable. Did the restore process flash the p920 baseband as well? If so then you will have lost the ability to get 4g regardless of rom.

i have the original stock Thrill rom available if you want it
please post for others
is there no way to extract the baseband from the lg source or a non baseband modified thrill?

i have the nandroid back up from my original firmware but it has some personal stuff so let me restore to that backup and wipe the data to make another backup.. sounds confusing but just give me a couple of hours + upload time lol

There's a return to stock thread in the dev section with a stock rom download.

But what about stock LG Thrill baseband?

Asking for how-to install rogers 2.3.5 on lg thrill with stock 2.2.2

I have an unlocked lg thrill running stock 2.2.2
Can anyone provide a guide on how to install the rogers 2.3.5?
Do i have to root my phone first?
Thanks a lot

Rogers 2.3.5 doesn't have root. Just so you know, but no.
You don't have to root your phone.
A HOW-TO is in the Optimus 3D section.
Installing any ROM from LG Flash Tool will erase all data.
Last but not least, if you really need help, I can do it for you over TeamViewer.

you dont need root to install it. just use the lg flash tool method

Bootloander??

Hi everyone!if someone knows for sure please tell me..If the ics update for o2x have locked bootloander we can't play with custom kernel...etc..ok?in that case we will have to flash 2.3 firmware again to have unlockend bootloander and flash a custom ics or jb rom with the working drivers?
Sorry for my English!!!!
Sent from my Optimus 2X using xda premium
yes. that's right.
There isn't still an official ICS Update for O2x... However, yes you should return on 2.3 or I think we'll unlock bootloader without problem with a Toolkit like Nexus One etc.
Yes i read right now on general ics discussion.thanks anyway

Use LGFlash Tool, be sure that you select the V10x ".dll" and that you delete the V20a .dz from the program.
Could you be more clear please.explain me the steps..if possible...
