Downgrade from 2.3.3 to 2.2.2 - T-Mobile LG G2x

Assuming that I am running a rooted 2.3.3, is it possible to flash 2.2.2? If so, how would I do that? Sorry for the noob question in advance..

This should do it for you:
[ROM] NANDROID Restore Stock Rooted Froyo 2.22 LG-P999-V10f (5-16-2011)
I don't think there's any way right now to downgrade the baseband, but everything else should go back to stock.

Thanks! I successfully flashed 2.3.3 rooted after installing cwm via nvflash. Do you know of any issues that may be caused by running 2.2.2 with newer baseband? My reason for wanting to downgrade is that 2.3.3 broke compatibility with orblive, and I can't get any other music/video streaming app to run as well.

I got an system update message this to update to 2.3.4, firstly will this update work? Will it restore my phone to stock? What are my dangers but accepting and applying this update being that my phone is rooted?
You will be able to download it but you won't be able to flash it. For ota updates, you need to be completely stock.

How to Restore G2x to Factory Stock Rom on 2.3.3 Update

Hey guys,
I recently updated my G2x to the 2.3.3 GB update via KDZ software update and successfully installed 2.3.3 but I need to return the phone back to TMO and I didnt backup the stock rom. Can anyone provide me with a 2.3.3 STOCK [UNROOTED] Gingerbread rom file that I can flash? Thank you.
PS: If I have another G2x and updated the phone to 2.3.3 update via LG updater, then root it. Can I use clockwork recovery on the new phone to back up the ROM and install it on the other phone that is ALREADY rooted to return it to UNROOT?
PLEASE HELP ONLY HAVE 5 DAYS LEFT TO RETURN TO TMO...

Upgrading from Froyo to v2.3.4; Already Have Root

I have the T-Mobile myTouch 4G with the stock ROM running Android 2.2.1. I have root and S-ON. If I upgrade via the OTA update to 2.3.4, will I retain root? If not, is it easy to restore root from 2.3.4 or will I have to perform some funky exploit?
You WILL lose root. Grab the rooted version from the Dev section to retain root.

yes, you will lose root if you update via OTA. so you should flash the rooted version. saves you a TON of trouble. if you DO choose to update via OTA however, then you'd have to follow the downgrade procedure to revert back to 2.2.1.
Thanks, folks. I think I'll just freeze the updater, heh. I can't be this bothered especially if I'm not getting the latest version of Sense.
Where i found the rooted 2.3.4 ver.?
you can get the rooted (OR UNrooted) version here

[Q] Updating rooted/s-off device for CM9

Hey,
I'm a little confused right now, and just want some clarification on a few things since I know if I do this wrong, my phone might get bricked in the process.
Right now I'm running stock HTC Sense 3.0 (went to my stock backup from my last ROM) rooted and s-off, with ClockworkMod Recovery
HBOOT 1.17
My end goal is to end up with a device where I can flash CM9, and have it work properly. And I believe I need the android 4.0/sense 3.6 update. Which I cannot get since I got my phone s-off
From what I understand I need to flash the stock recovery to be able to install the ICS OTA update, so my device will actually run CM9.
Where I am stuck here is what file do I need, and do I flash it just like a ROM?
Any help would be hugely appreciated!
Thank you
You need to update the firmware to run any ICS ROM.
Once you update the firmware you can flash CM9 like any other ROM.

If you flash a JB ROM you won't have to flash your bootloader again, if that's what you're trying to say. But if you want stock JB, you have to unroot your device.
