Need to go back to 2.1 EPE54B build

Im using cyanogen 6 RC2 and tried also RC1 and have major battery draining issues ive tried everything
At this point anyone know how I go back to the stock 2.1 EPE54B build (ATT 3G bands)?
Thanks for any assistance

your phone is rooted so all you need to do is look for a 2.1 Rom from your phone forum and then flash that Rom. This should take you back to 2.1
Also if you did a nandroid backup before you upgraded to 2.2 then you can boot into recovery and do a nanadroid restore to take you back to 2.1.
If you do not have a nanadroid back up then that is why we always advise to do a nanadroid backup before flashing any Roms....

I use titanium is that ok? Also do I need to flash the radio back to the older one or can I keep the froyo one?
EPE54B update zip should be ok from here right? Also if I do need to flash back the radio can I also use the files from here?

Ok titanium is ok, but before you flash back to 2.1 I would recommend a nandroid. A nandroid back up would restore your entire system/os just,in case u need to restore your system.
About the radio: you do not need to flash back the radio, this is not required.
Now you can use any of the stock 2.1 rom of your choice from this post http://forum.xda-developers.com/showthread.php?t=744605
What I would have not ks this:
1.Titanium back up
2. Nandriod back
3.wipe data, factory reset, etc
4. Flash 2.1 rom
Reboot and u are back to 2.1 stock
Remember do not flash back the radio

Sorry for all the questions but I know with CM you need to also install google add ons for the market and maps and such. Is that also the case with this? Or since they are stock they automatically come with it?

NP. Anything that's stock will be included in the rom. It may not be the latest version but you will have an option to update once you lunch the market.
Also u,are doing a titanium backup so anything that's missing you can get back. Once you flash back u,can,check,to see if you have those apps, if u don't then just install and run titanium backup. You can run a restore operation to get all missing apps +data.

Thanks. Too bad I can't find the manual stock 2.2 in order to install it and try. On 2.1 I would get the Ota update request but it would fail saying invalid signature. Think it's cause of my recovery image.

Went to CM V5.0.8 and havnt had an issue since so there is a bug somewhere in 6 since a few other people are having similar issues as well

[GUIDE]Updating to 4.22.651.2 OTA WITHOUT flashing a new ROM or wiping your Phone

This assumes you:
- Have the latest FROYO OTA installed 3.70.651.1
- Have some experience working with flashing things in recovery
- Have NOT deleted/uninstalled ANYTHING in /system
- Have defrosted any bloat you froze with Bloat Freezer or Ti Backup Pro
- Have S-OFF (Used Unrevoked Forever or a version of Unrevoked3 that includes Forever)
OK now let us get to it.
1. Go ahead and download the OTA like normal on your phone, but DO NOT install it.
2. Using a file manager copy the OTA zip file from /cache to /sdcard
3. Using Rom Manager, flash Amon RA Recovery 2.3 (Down at the bottom)
4. In Rom Manager, click the Reboot into Recovery button.
5. Select apply zip from SD Card and flash the OTA zip file that you put in /sdcard
--10 Minutes later.....you now have the UNROOTED OTA installed just as if you installed it normally--
6. Download the 2.6.0.1 ClockWorkMod Recovery zip from here and place it in the root of your SD card
7. Under settings > applications > disable FastBoot (re-enable this when you are done with the whole process)
8. Power off and reboot holding Volume down. The bootloader will scan and then will and ask you to press Volume up to install. Reboot.
9. Delete the PC36IMG.zip file from your SD card and place the attachment below in the root of the SD card.
10. Power off and reboot holding Volume down and then select recovery to start CWM recovery.
11. Choose apply zip from sd card. Choose select zip on sd card. You will see the SU file on the list, flash it to root your phone. Reboot.
You should now be rooted and can upgrade the recovery now to whatever style and version you want!
Enjoy! Please click the THANKS button if it worked for you!

Very cool!!

Great info ..hey if I follow these steps and skip the last part will my phone be stock / uprooted and good to go.for a trade in or repair? I've been trying to figure out the best way to unrest when.e3d comes out

I never updated to 3.70. I'm assuming I can do that the same way, root again, download the gingerbread, and root again?
I'm thinking it might just be easier to flash the rooted ROM and radios, but I'm not sure what's best.

if you have amon ra recovery (and a stock rom), you can simply download and click install.
I clicked install, amonra booted up, detected and ran update, click reboot, then the stock recovery will be active and updates the radios, once back in to sense, you can reinstall amonra or clockwork, then SU
worked for me.
http://forum.xda-developers.com/showthread.php?t=1109230

im curious why the title says "WITHOUT flashing a new ROM" yet you are clearly flashing the rom in amon ra. sorry just got to nit pick

what happens if you have deleted some system apps. Such as nova and blockbuster. I saved the APKS on the SD card however but I did delete them?

Well I wouldn't want to try it unless your prepared to do a full ruu reset if it fails.
the OTA is like a patcher, it deletes unneeded files, adds new files, and updates existing files... if its not completely stock it may (or may not) cause an error which the updater can't handle, and then you may be left with a half upgraded system.
if you nandroid *before* downloading the ota, you should always be able to go back, assuming you have perm soff from unrevoked forever.

it should run whether you have removed files or not. if it tries to delete a file that does not exist the script will just skip it. op i think you have bit of confusion going on though. you were only able to reattain root because you are s-off from unrevoked forever. if you are not s-off and do your method, which is no different then just excepting the ota and letting it do its thing btw, you will loose root until this new ota is cracked. just fwi, there was no "magic" from you flashing manually, the same script is ran and the same files are moved and patches are made regardless.

cant I reinstall the apps and put the apks in their original system folder?

Lol OK so which one is it? Can n just accept the ota and run? I'm rooted on stock rom, but I deleted nova and blockbuster from the system? I know I will loose root which I got by using unrevoked 3, but I just want to know if I can do it without bricking the phone. Ty

shouldn't be any worry about bricking but make 100% sure you are s-off from unrevoked forever and you should be able to re-root pretty much how the op outlined.

im currently running cm7. if i go back to a rooted stock froyo rom, will this work???

confused. I just don't understand why you wouldn't download the rooted version of the ROM from here on XDA and just flash it like a normal rom. Maybe I'm overtired and missing the point.
To me, its like this. If you're rooted, and want an OTA update, just wait for the devs at XDA to go through it and root it, and make it available for download. Then just download it and flash it. You get the same exact update that way, as if you took the OTA from sprint. Except this way you don't risk losing root, and your good to go.
If you're not rooted and your phone is stock, accept OTA like normal.
I don't understand why all this extra stuff needs to be done, and add more to the confusion. If your rooted, updating to the latest is simple. Download it and flash it in recovery.

Do a full wipe and flash like any other rom you've ever flashed before. You'll then be on the latest and greatest . (you'll probably be going right back to CM)
EDIT: and to the OP, sorry that I don't agree with you. I just find it more confusing that way, and I guess that whatever the point of doing it that way is, is sailing miles above my head.

That link I supplied a couple posts up is a completely 100% stock and rooted version of the OTA update.
This is from the first paragraph of the first post of that thread.
"Stock 4.22.651.2 ROM, rooted and ready for your flashing pleasures. This is a completely stock ROM that has had nothing done to it outside of rooting & deodexing, it's not even zip aligned yet (sorry DrMacinyasha)
As always make sure your wipe your dalvik and create a nandroid before flashing."

thanks for your insight. only thing I am confused on at this point is why there are kernels listed to flash from May just below it? wouldnt the htc stock kernel from the ota be in this rom already? seems like alot of folks are looking for newer kernels to flash after flashing xhaus rom. Any insight would be great. thanks again!

I was a little curious about why those kernels were linked there too. I honestly haven't really kept up with thread, because I don't have an interest in flashing the update to begin with. I noticed those kernels are from May 4th, so it doesn't seem like they'd be the most current one. Without reading that thread, I first would've presumed that the kernel that comes with the rom would be the one to use. So, you've read through the thread and you're seeing that people are having trouble with the kernel that the rom comes with?? I'll take a gander over in the thread in a few minutes and see what I make out of it.

Well I f'd up and installed the latest update straight from sprint, instead of waiting for the rooted version to come out. I guess I thought I would find something exciting, but now I would realize it was kind of worthless and want to go back to a different rom like miui or vaelpak. I am s-off with unrevoked. Is there some combination of the steps listed I can use to back out of this?
Let me take a guess...did this update my radios and hboot to a version that would be incompatible with these roms?

unroot confirmation

hey all, currently have a g2x rooted with cm7, and i've been looking to unroot;
just to make sure i dont do anything stupid, i wanna run this through with you guys:
first i would flash the stock 2.3.3 ota rom for g2x
then use the http://forum.xda-developers.com/showthread.php?t=1056847 (one click nv flasher) to get back to lg stock recovery by clicking 'flash stock recovery' (do i need to dl anything extra for this?)
then im done, correct? if i boot up, ill get all the stock rom and apps and bloatware and etc back right?
thanks!
edit: how do i know which version of clockwork mod i have installed? im not sure if i did the external sd support or not...

You've gone back to a stock ROM, you've gone back to the stock recovery, but you haven't actually unrooted.
Whichever method you used to root, you should be able to use that same method to unroot.
UPDATE:
I was originally under the assumption that your 2.3.3. ROM was rooted. If it is stock you should be fine.

sorry for bump, but i read in tga_gunmans post that ppl should flash a rooted 2.3.3 rom and use superoneclick to unroot...would my method work too?

No your way would not work because the stock OTA by xboarder is rooted. Do what tga_gunman said. Flash the rom, use my unroot zip in CWM (deletes root files) and then flash the stock recovery. Busybox will still be on the phone but nobody should be looking for that.
Unroot zip: http://www.mediafire.com/?2vr7cmgg7qcdn14

Easiest way to confirm if your not rooted would be to install Superuser from the market. It'll tell you if the phone's not rooted.

There is an app on the market called Root Checker which is free. It will tell you if you are rooted or not.

A little extra help for me?

Thanks for your help jboxer. Forgive my noob-like understanding of rooting/unrooting terminology. Hopefully you'll be able to understand what I did.
Last night I went ahead with the unrooting process on my G2X which was running Gingerbread & CM7 following this youtube video (can't post link due to noobiness: watch?v=ryGIv8KQVIE), the order that this guy goes in is:
1. Wiping all cache/user data/formatting in CWM recovery
2. Restore to a barebones stock data in CWM recovery
3. Flash to go back to Stock using OneClickRecovery
4. SuperOneClick to unroot phone
What I ended up doing was restoring my phone to the backup that I created on my sd card when first rooting my phone rather than download that zip file in the video description which is a completely fresh start.
However, whenever I flashed to go back to stock using OneClickRecovery, it gave me that total barebones fresh start where I had to completely set up my Android from the first start screen and I lost my backup. Also, when I go to unroot the phone with that zip file, I don't know how to 'install from zip' after I've lost CWM Recovery menu. So, I flashed back to CWM so I could recover my backup from my SD Card again and install the 'unroot.zip' that you linked and it ran alright and I restarted, but I still had 'SuperUser' in my App drawer telling me that I was still rooted.
I ended up calling it good last night after spending two hours on it. I left my phone rooted, with CWM recovery still on my phone, but I at least I had my backup Gingerbread image with no CM7 mod. So, my phone is functional, but I would like to complete this process of unrooting completely.
Could you perhaps give a little guidance and clarity to what I'm missing or not understanding? I'd love to unroot/flash back to stock recovery/remove all evidence of rooting AND keep my recovered backup that I have before I even started rooting my phone.
Thank you so much for all your help, everybody.

[Q] ¿Help getting back to stock rom?

Hello guys
First of all, I'm new in here, so I don't know much stuff.
I recently got my transformer and wanted to check out the Android Revolution HD rom. Before flashing it, I made a backup using CWM.
I tried the rom (before installing it, yes, I did the superwipe thing) but didn't like it because the gps issues. I wanted to go back to stock and did again a superwipe and then made a restore from the backup.
When I rebooted my tablet, the configuration screen came up and started freezing and rebooting. I tried re-flashing the backup but it kept going on with the crashing and rebooting stuff.
I've been searching far and wide on how to go back to stock and I have found just the nvflash but my serial starts with B70 so I know I can't use it.
I decided to reflash Android HD Revolution because it's the only way the tablet will work, but I would love to go back to stock so I can use the gps properly.
So, Is there any way I can go back to stock? If this means something, I live in South America, so I assume I need a WW thing or whatever that means
Thanks in advance for your help

There's a flashable rooted stock ROM here

Thank you vyer much, I had seen that thread but since it said the following:
This will not work unless you have:
1. clockworkmod
2. STOCK firmware (root is fine)
3. the US or WW firmware
4. The appropriate prerequisite firmware (e.g. the latest firmware before this update)

Would you mind helping me understand the rules for flashing this version please? Right now I'm running Android Revolution HD 2.3.0

Reboot into CWM recovery
Clear data and flash ROM. You can use Titanium backup to save apps and data if you don't want to lose anything.

In my understanding that is not a (complete) ROM but just an OTA update for a stock rom. Cannot be used to replace another ROM.

That's the same thing I understood from the ROM flashing rules.
I guess there's no stock rom that I can flash? It can't be (or can it?)

OK this is the link that has the full ROM. CWM flash-able.

Baseballfanz, I've already tried that one, but it didn't work. Thanks though.
Neidlinger, thank you very much for pointing me in the right direction! If I ever find another GPS problem (since I haven't found one since I reflashed Android Revolution) I will use this tutorial.

[Q] Restore backup to get ICS OTA Update?

Before I go wiping my device again in anticipation of getting the OTA ICS update...
I made a backup of my device when I was on the original Honeycomb build after rooting. I then switched to the Prime ROM. I'm assuming that I can just restore my Honeycomb update, get Root Keeper and install the OTA update. Am I correct, or is there something that will stop me from doing this?
Edit: Also, when restoring a backup using CWM, does it automatically wipe the device before restoring, or does that need to be done manually?

I believe you also need to restore the original recovery. The last time I tried to flash an upgrade on my rooted stock image using CWM, it rebooted after downloading and rejected the (non-stock) recovery. I'm guessing the ICS update will require a reboot into the stock recovery as well.

Indeed, no OTA update when original recovery is not installed.

I looked around a bit and saw how to unroot and restore to stock recovery... is there an easy way to just restore stock recovery? My plan was to restore my stock backup (to get off revolver) and then can go from CWM -> Stock, I just wasn't sure how to do the last part without undoing everything and fully returning to stock/no root.

It's also very possible that Root Keeper will not work since this is a new firmware form the ground up.

OTA Rootkeeper do not work if the system partition is formatted. Which is not the until now. Also people reported OTA rootkeeper worked to get root back after ICS update.
Otherwise use vipermod option 1 to root on ICS.

I just did exactly this. I had a nandroid backup of my original stock honeycomb so I restored the backup (I had some problems with the kernel after restoring from Revolver with some OC kernel, but flashing "plain" Revolver and then restoring the stock rom from the backup did the trick).
After that I made sure that everything is OK - I checked that I'm on the correct pieces of the software, in particular the kernel. All looked fine so I pulled OTA update, but before applying it I had to restore stock recovery. For this I used the stock recovery linked in this thread: http://forum.xda-developers.com/showthread.php?t=1154947 Just downloaded it, placed it on my SD card, rebooted into CWM recovery and flashed it (pleas note - I only downloaded this single file, not needed to download any other files mentioned n the above thread since I already been on rooted stock rom).
After booting the TF again, I made sure that my root is backed up with Supercurio's Root Keeper, then I applied the OTA and after a few minutes I was happy user of ICSed Transformer.
Please note that what worked in my case may not work in yours though. So be careful, think twice, and keep in mind that it's your decision - your risk (and if something goes wrong - your brick )
BTW, all applications, data, etc. are still in place. Root was restored via Root Keeper. Then I downloaded some updates of applications and so far I'm fine.
