CM7 B#55 Downgrade to Stock 2.2

All,
My G2 is having some hardware issues and I am having it replaced. I need to downgrade to Stock 2.2.
I have not been able to find a tutorial to complete this task. I have tried flashing the stock rom however the phone just freezes at the HTC logo...
any ideas how I can downgrade?

Did you flash an older version of CWM (pre 3.x) before flashing the 2.2 rom?

No. Ill do that first. Thanks for the reminder.

[Q] ROOT and factory reset

Hello
first, sorry for my bad english...
here is my trouble : i rooted my HTC desire with the unrevoked method, and it went well.
then, i have made a factory reset and applied the OTA update from 2.10 to 2.29 (OTA_Bravo_Froyo_HTC_WWE_2.29.405.2-2.10.405.2_R_P_release8gn61bgo3rswcw24.zip)
but now, when i'm trying to use an app that request the SuperUser rights, i don't get the pop up asking for this authorization... (i.e. titanium backup)
and i can't update the superuser app in the market...
i tried to re-root with unrevoked, but that didn't solve my trouble...
i need your help
thanks
Adrien

Never apply OTA updates on rooted phones.
You still have CWM recovery? If yes reflash your/a rom.
Otherwise use a ruu to unroot properly and reroot.

yes, i have still CWM recovery
i don't understand what you mean with /a rom ?
and, if i do this way, how to update from 2.10 to 2.29
thanks
Adrien

You can reflash the rom you already have or flash a new custom rom. The custom rom will most likely be the newest version.

[Q] Just a Question. . . (SOLVED)

Can I downgrade from the official T-Mobile US 2.2 (34.4.9) to the official 2.1 (6.36.0)?

no, you can not, there are 2 elements in the new bootloader that prevent downgrading

i think you need use restore other's backup

Yes you can by flashing the the sbf for 2.1

I need an answer. Can you, or can you not? Has anyone tried it and been successful?

I tried and been successful. The code group versions are 4 for cg31 and cg39.

Awesome Now I can flash with confidence!

It absolutely works!! I've done it more times than I can count... In fact you can downgrade back to 3.6.360 coming from any rom currently available to date.. Well I have never tried coming back from the new Arabic 2.2 Rom that just dropped (3.4.3-20) but I've flashed back from 3.4.3-11

I flashed successfully

[Q] Root without OTA

I'm currently on 2.3.3, and don't want to unlock the bootloader due to warranty, so I wanted to try the Gingerbreak option, but my carrier doesn't seem to do OTA updates (currently no 2.3.4, no 2.3.3 when I got the phone), so I'd be stuck on an old firmware. If I do unlock the bootloader, how do I get root while keeping the stock ROM? I don't want to lose the native emulator.

You dont loose the stock rom unlocking the bootloader. Just all your data. Furthermore the native emulator has nothing to do with the rom you use, each classic PS game comes with it's own emulator built into the .apk file.

So I could use the FreeXperia ROM and PSXperia will still work?
Also, how do I backup my current stock ROM? Root, and backup with that recovery mode app off the market?

Yes as far as i know, as long as you install some prerequisite apps like preinstalledservices.apk. You can play the classic PS games on cyanogenmod You cannot use nandroid backup (from recovery) without unlocking your bootloader. There are some backup apps on the market but they all require root too. That recovery mode app you talk about, you mean rom manager? well atm rom manager is not compatinle with any of the 2011 xperia devices

Oh, so we have to install and backup ROMs through ADB? Does the ClockworkMod recovery work?

Ok, so I was on 2.3.3, unlocked bootloader, everything was fine, then I flashed the play_modded.img using Fastboot as said in the "Root your Play" thread, it worked, but I booted the phone up to find that it's 2.3.2, old as hell, the UK version, won't recognise my New Zealand SIM, and everything is force closing. I reset to factory settings, still no SIM but most force closing was fixed. I noticed the MTP thing force closes though.
I'm now downloading the 2.3.3 UK ROM, but I want my original Vodafone 2.3.3 NZ/AUS ROM, then install Doomlords kernel for autoroot. SE PC Companion isn't showing an update option to restore to said ROM. ):
Edit: Installed the 2.3.3 UK ROM and Doomkernel and everything works fine! Thanks, AndroHero.

[Q] OTA updates on rooted phone

Just a quick one.
There is an ota update available for my wifes Wildfire S which has been rooted. If I go ahead with the update will my root 'stick' or will I need to flash it again? Its running a stock rom and running 2.3.2, the update is 2.3.5.

Root will probably go......try using OTA root keeper...that might work
And i've got a quick one too
THERE IS A Q AND A SECTION HERE

Tried the ota update but all I got was a picture of an explanation mark and a green android. I'll just manually update the stock rom from a zip. I use Android revolution HD for my OneX, is something similar available for the wildfire S? I can see plenty of other roms on here but I want one that is based on the HTC stock rom like Android revolution is.

Quick one. You'll need stock recovery.

Do you mean I need to take cwm recovery off and replace it with stock? Can't I just flash a new stock rom (and maybe a new boot.img) on to it?
