How to revert to stock rom? - AT&T LG Optimus G

Hi, I have a rooted LGOG with 4.1.2 and I need to revert to stock as I am going to return the phone for another due a dead pixel that has popped up. I've seen some files but they're not in .zip format to flash over recovery. Are there any .zip stock roms?

There's a stock ROM in the development section. I can't remember which but its by SnowLepardJB or TheCubed.

You need to factory reset in recovery and flash stock using lgnpst.

1. Does all stock roms have the same recovery?
2. If so how can I pull a stock recovery and push it over a stock Rom with cwm...
(replace cwm with stock recovery) in order to be able to get otas

In the tar you download from sammobile.com, there is a file called recovery.img. This is the recovery. Just be sure to download the rom suitable for your device. Then you have 2 options:
Put the img in a .tar and flash with odin
OR
Download this file www.mediafire.com/?w45j8i0fcj0wck0, which originates from this thread: forum.xda-developers.com/showthread.php?t=1171089&highlight=lorddeff07.
Replace the img with your own and flash with cwm.
I have used it to flash pershoot's recovery to my 7500 and it worked. I don't know whether it will work for stock, or wifi only version, but I see no reason why it shouldn't.
Please report back as to what you tried and if it worked.

Why don't you just wait a day or so for one of our awesome devs to post a rooted OTA after it drops, and then you can just flash it.
But I think the answer to your question is "PDA"...

I feel you m8... But you know as soon as Sammy drops the ICS update the great devs on XDA will pop open the OTA, root it, tweaked it and debloat it. And that will be done most likely in a few hours of the update. And remember if you do the OTA, you most likely will lose root until the devs setup some new root files.
Just saying...

Yeah I know can always flash back via odin an old hc rom re- root re- cwm /wipe factory reset and flash cm9 xD
Just Wish pershoot had a kernel control app to get proper and full control of the tab as I have it in my gnex with cm9 and frankos kernel app

I'm assuming you don't already have clockwork recovery on your phone? If not go here http://forum.xda-developers.com/showthread.php?t=849028 and flash clockwork mod recovery with the update.zip in section B) in the guide. Once you have that taken care of you simply go pick a rom from the development section and follow the instructions which are usually factory data reset, wipe cache and wipe dalvik cache from recovery menu then install zip from sd card. Some ROMs recommend flashing a gingerbread ROM before flashing an ICS or JB ROM. If you want a completely working phone I would recommend one of fishman or moped ryders 2.2 ROMS, ICS has the EU bug and bad gps, and JB is still in beta builds I believe. Just remember you can always upgrade by flashing with no problems but if you ever want to down grade you must Odin to stock 2.1 then go from there.

Look at my signature for a guide on how to install ICS ROMs. You'll need to look at it on your PC though and not the phone app.

I don't think he can see or SIG on xda premium, but anyway flash a froyo GB or ICS rom then flash the jellybean ROM.
Sent from my Jellied out Vibrant sandwich.
Check out the Hellybean nightlies Here and here and the Devil Kernel for ICS here and Jelly Bean here for the Galaxy S and variants.
Or you could use Odin to flash a gingerbread bootloader then flash jellybean right then.

[Q] Chaos/Hell opened up... should I unroot?

I opened up the gates of hell. First installed international MJ9 ROMs. Then erased my internal after backing up EFS to the internal... derp.
Now I don't have IMEI info. it's NULL.
I am growing tired of reading non-Verizon-GNII topics not helping much to solve this issue.
And for some reason my phone is keep spamming "FACTORY MODE ON"
I wonder if I unroot my phone and upgrade it to OTA 4.4.2 it will fix everything.
Any ideas?
What should I do to go back to stock 4.3 or 4.4.2?
P.S: Got out of Factory Mode.
I would try to odin back to factory for what ever you had prior to this. Don't take the ota or you'll be stuck there. . And if you weren't already on 4.3 don't go it either. Totally different hell if you do, one with locked bootloader and no root access...

I had alliances Rom 4.3 before all this happened.. What do you mean by Odin back to factory?
In the android development section for the vzw note 2 there's a sticky on returning to stock. Follow the path for flashing 4.3 factory image in odin

Ah nice thank you!
Is this actually unrooting my phone? I mean will this lock my bootloader and prevent me from installing custom roms in the future?
Thanks so much for your advise.
Yes it will. That's why u wanna flash whatever u had before. If you had 4.3, flash 4.3. If you had an older image flash it. The thread has everything you need. If you can do 4.1 then you can unlock the bootloader again. If you flash 4.3 you can root but not unlock. If you flash 4.4 you are bone stock no root possibly forever

Sweet... I just installed rooted stock 4.3 by beanstown106 and everything's back to normal.
All thanks to you vlx600d.
I know I asked you this once before but I just want to double check:
- I am able to flash 4.4.2 ROM from my 4.3 ROM without a problem?
- Can I flash 4.3 back from 4.4.2 ROMs?
Thanks so much!
For anyone with my kind of problem, try installing Official Rooted Stock 4.3 and flash the modem via Odin per the instruction in the link.

You should be fine to flash 4.4.2 and revert back as well
Glad to hear your back up and running.

Extract it from any stock ROM you have, or search for that in general section. It was posted in a thread.
