I upgraded my wife's g2 to the official tmobile gingerbread release (used the pre rooted deodexed gingerbread rom) and need to return the phone to tmobile for an exchange. Before the upgrade to gingerbread I rooted and enabled permanent s-off.
1. Will I have any issues just flashing the stock tmobile 2.2 rom through clockwork recovery?
2. Once downgraded will I have to root again to go back and undo the permanent s-off
3. Is there a rooted stock rom available to flash? Want to be able to restore apps + settings while awaiting a replacement?
dig around the forums for an original PC10IMG.zip of the shipped rom and flash that through bootloader
Any issues using the rom in this thread. Looks like its a flashable .zip file.

Can I flash the above rom through the bootloader? Want to make sure I don't brick the phone before I do this.

Hi !
You can not downgrade at all because the install of an older PC10IMG.zip will give you a "main version too old" error.
Normally you solve this by using misc_version to change the main version string in the misc partition.
But to do this you need (temporary) root access.
All published temp-root methods (rage and it's derivatives like visionary, z4root, ... - psneuter - gingerbreak) have been patched in the official T-Mobile G2 Gingerbread release.
So enough background info for now - This firmware version is not rootable and can not be downgraded (for now).
Have fun - Guhl
Of course we will post and update if the situation changes
I have this gingerbread rom installed. Can anyone confirm that this version cannot be downgraded.
Flashable version of PC10IMG_Vision_Gingerbread_S_TMOUS_2.13.531.8 Leak, that football posted, and yes this is the final release.

Wait, you got a rooted version of it installed?
If yes, you can use misc_version to set the main version back to a lower or equal value of the rom you want to install and then install the PC10IMG.zip through hboot.

how i thought you need temproot for that
So I flashed the rooted gb rom above through clockwork. Will I brick my phone if I flash the stock rom I linked above through clockwork? Is it really this hard to go back to stock?
I think there is a lot of miscommunication going on here. I think the problem is that users are having a hard time differentiating between the unrootable leak and the rooted leak.
I'm having to send my g2 back also, I'm rooted, s-off'd, and using the rooted version of the tmob gb leak. ive got cwm installed too, should I be able to use the pc10img to completely wipe, set s-on and go back to 2.2?

Will I lose root by installing it? At the moment I have RA-Hero 1.6.2 and the rooted HTC 1.5 ROM
Yes, you must wait for someone who root it so don't update but you can flash some roms like VillainRoms or Cronos or Modaco which are based on the 2.1 update !

Unroot for official or install a copy from the dev threads

Short answer; no. You don't need to unroot to update OTA if you're running a stock build. The update will cause you to loose root though.
Just to clarify for the sake of caution, I installed the leaked 2.2 update. Can I install the official build OTA or do I need to read up on Odin and manually update it? Thanks.

From what I've read, in order to flash the ota you have to have the stock recovery, so your options are to odin the modem and flash one of the roms through cwm -or- odin the entire .tar and then run the one-click-root.

Thanks. But I can use the one-click-root to root my phone again, right?

you could and it will work but why go through the extra work ??
use odin to update the modem (very easy) then go grab the ACS DK28 ROM. it's already rooted for you and it can be flashed via Clockwork .. very easy to do IMO.
Can I flash the ROMs available in this forum and later if for any reason I didnt like any, can I flash the original Froyo on my HTC Wildfire?
restore it as it was shipped.

Of course you can. Nandroid backup or look for official FroYo modified without new hboot.
Because if you flash the new official Froyo (RUU) or OTA update, you won't be able to root it nor install any other ROM. Otherwise, you can install an older 2.1 RUU, which can be rooted then.
Ask me for more help if you need

As far as i have experienced with my wildfire,once u flash RUU froyo on your wildfire,u cannot flash back an Eclair RUU as the latest HBOOT wouldnt allow you to overwrite with a previous version.
If I am wrong ,please correct me.
I dont want to downgrade to 2.1 but get back 2.2 original

Yes, you can't downgrade with the official RUU, because of the new HBOOT. But there are now SAFE roms extracted from RUU, so is the RUU without new HBOOT, so can be rooted.

But now, which version you have? Official update 2.2.1? If you have updated by wifi when the phone showed "Update available", you can't do anything now, until the official Froyo can be rooted.
If that's not your case, explain in which situation are you right now.
Hi everyone,
I have a htc desire z and have it perm rooted and S-OFF.
Now i want to go back to stock with my Nandroid backup i've made before flashing other roms.
I can go back to my nadroid backup but then i want to update my stock rom with the update that came out some time ago. But for that you have to Unroot and S-On again... HOWWWWW CAN I DO THIS???
Which update do you want to apply to the stock ROM ? You don't have to unroot and S-ON to apply an OTA update, and currently all the known OTAs are rootable (you will lose root but keep S-OFF if you got it via gfree).

Well, i was trying to install the OTA update but it didn't work.
Couldn't install the update.
So i thought it was becouse the S-OFF...

If you have custom recovery (CWM) then I think the OTA won't work. But you can always just flash the stock recovery back on (e.g. via fastboot or flash_image) then you should be ok.
Or you can just flash the 1.72 ROM complete, though you will lose all your data/settings.
Sent from my HTC Desire Z
So... if i flash stock nandroid back.. and uninstall custom recovery what is ROM manager i guess, i can update stock with the OTA update?
Or how do i get rid of the cwm otherwise?
Sorry if i'm asking stupid questions thnxx for your help!

Yeah just flash the stock recovery back on via fastboot or flash_image, then you should be able to apply the OTA, assuming you haven't done other stuff that might break the update (e.g. removing stock apps).

Ok, i'm gonna try it now. First uninstall rom manager and then try then ota update.
But i'll loose my root you're saying... is it rootable again for now? Couse i understand that otherwise i can't flash another rom for a while...?

The 1.72 DZ OTA ? Yes, that is rootable via the psneuter method now, it's just you cannot use gfree to get S-OFF at 1.72, that's why a downgrade may be necessary for some (i.e. if you are at 1.72 and S-ON).

similar question here. I didn't made a backup for the stock recovery module. If so how can i restore the stock recovery? Are there any available on xda?
So I'm rooted on 2.3.3 with the official ota, I'm suffering without a. Oc kernel, is there a way I cam downgrade to like cm7 or 2.2 rom with a kernel? Thanks!
Rooted with the official OTA?

Or is it more like "was rooted before upgrading"?
Yeah my bad, I waited til they released a rom with the official upgrade, hope that makes sense
If your rooted and just running a rooted "official update" ROM then you can flash whatever you want. As long as you didn't accept the Gingerbread upgrade pushed out from Sprint and still have s-off your good to go.
