[Q] How to downgrade 2x back to 2.2.2 from 2.3

Hello, I dough I can do very much at this point then ask for help.
Yesterday I used LG KDZ tool to install update to my Wind Mobile LG Optimus x2 which is P999. With the help of KDZ I got the T-Mobile update to 2.3 on it and honestly I hate T-Mobile update it just sucks so much.
I did some reading around and try to flash the ROM and some how put on a backup that was also posted here on the forums of stock Wind Mobile LG Optimus ROM.
The problem is I never rooted it while it was at 2.2 and at 2.3, I can't root it with one click rooter it just does not work I gets to Step #7 and you get device rooted but its actually is not so I can't restore to the backup I download from XDA.
I honestly would like something similar to stock 2.2 that comes with WIND LG so if you can help out to either restore it to stock ROM or in some way move it from T-Mobile update back to 2.2 without the T-Mobile preloaded and other T-Mobile blobware crap that comes with it.

Hello!
Did you try this...

[Q] How to flash back to stock rom and unroot my P970?

Dear All brother
I just want to flash back to stock rom and unroot my P970 like initial status. Is there any tools or method to do so?

It's very simple, just follow the Tutorial: LG P970 (P970H) unbrick/flash using SmartFlash Tool and install whatever version of firmware you had initially, you can find V10 firmwares on the Firmwares LG P970, P970H thread.
If you want to get to the official V20 firmware, just upgrade your phone using the LG program (the one that came on the CD with your phone).
This way you'll have an "official ROM" on your phone and it won't be rooted either (it's just like it came "from factory").
Btw, you'll loose the root and the recovery functionality, but i think that's what you wanted in the first place
EDIT : replaced Samsung with LG, i was reading up on modifying my Samsung Spica and somehow mixed up the postings

back to stock 2.3.5 without KDZ files

Ok I am going to post this because it worked for me several times. If it works for you, great, if not, sorry......I am assuming zero responsibility for bricking your phone ….. So I was thinking there should be a simple way to go back to stock 2.3.5 using just the "LGMobile Support Tool" The problem is that it won’t let you run the update tool if it sees that the operating system version is correct (i.e. running any rom that is 20p based) so what I did was download an O3D rom and placed it on the phone (ThiaiZO3DV2.7.1GB to be exact) I used CWM to install the rom. What this accomplished was to change the OS version but not the baseband. When the rom was loaded and working I turned on debugging and then used the "LGMobile Support Tool">>>(the tool can be downloaded from the LG web site) it will now update the phone to stock 2.3.5 without giving you the message that says your phone is up to date. If you get stuck in a boot loop (as I did ) just pull the battery put it back in and boot into stock recovery using volume down , 3d button and power and just do all the wipes then reboot….I hope this helps someone

Ok,
just to be clear you were coming from the Optimus 3D baseband and rom and successfully flashed to the US Thrill baseband and rom using this method?
I just saw that gingerbread is finally out for the Thrill and thought i'd flash back if there was an easy way. (I have been running the Optimus 3d baseband and defualt rom for quite a while now)

Then there isn't much reason to switch to v20p if you are already on gingerbread unless you miss the at&t bloatware

But aren't I missing one of the bands (or frequencies) that at&t uses?
I have never had too many troubles in service but I do notice I almost always have less bars than other At&t users in the same locations

No I was on the Thrill ATT baseband ....... This is just to go back to stock if you are already on US baseband....Sorry I should have been more clear..... Say you were using a custom rom like "AcuraTeam_v.20P" which was made for the thrill, and you wanted to go back to stock 2.3.5 but you didnt have a clockwork mod backup of it on your phone. If you were to try using the "LGMobile Support Tool" it would tell you that your phone was already up to date and didnt need updated. So to get around this without having to use KDZ files to get back to stock 2.3.5 you would install the O3D rom which changes the version number of the operating system which tricks the "LGMobile Support Tool" into going ahead and reloading the phone with the latest ATT update.

I have 2.2 Froyo... Need help

Hello, I'd like to update my phone using Smartflash.
I have an official V20B rom which is rooted. I would like to install a new official rom but i'm completely lost when it comes to choosing the right version !
Where can I get the official V20S stock rom (which can be installed with smartflash)
Also, is there any official ICS rom ? (same, for smartflash), if so, is it fully stable ? Where can I get it ? (LG Mobile update says my phone is up to date... Huh)(I have read that you need to change the boot partition or something like that with ICS roms, is it valid for official ICS roms from LG too ?).
Do I have to unroot my phone before installing a new rom with Smartflash ?
Thanks.

1. Make sure that you have P990.
2. V20B should be a gingerbread.
3. If you read one post below yours, you could’ve find exactly what you ask official ICS for smartflash.
Cheers.

I actually have V10B sorry !
I will update via LG Tools with the kdz instead of smartflash. Is there anything to do specifically to keep my data in the phone or is it saved automatically in the LG Tools update process ?
Thanks

I think updating via LG Tool doesn't erase data on your phone... however I would strongly advise you to synchronize your contacts with gmail and backing up you apps with titanium backup in an external sd card.

Update via LG Tool didn't erase my data when I went from 2.2 to 2.3

Yes, flashing kdz do not wipe anything.

[Q] Backdating LG Optimus Black To 2.3.4

Recently i updated my LG Black to 4.0.4, using LG's Mobile support tool. After upgrading, i decided that i don't like ICS on the LG Black, and wish to go back to gingerbread. I've tried googling around, but cant find instructions on how to do it.
Does someone know of a method that doesn't use CWM Recovery.
Regards
Andrew

You'll a GB ROM image (factory).
I'm not sure what else.
I'm guessing that you'll:
- Need to unlock to bootloader
- Use a tool like smartflash to install the GB ROM
I'd read thoroughly through: http://forum.xda-developers.com/showthread.php?t=1111771
I'd do a search in this forum for "downgrade", "factory". I wish I could be of more help, but I've never personally downgraded a phone to factory.
