CM6 back to stock 2.2 (rooted) - EVO 4G Q&A, Help & Troubleshooting

I apologize if this has already been answered, but I wasn't able to find an answer on the forums.
I was successful at flashing the CM6 stable ROM to my EVO 4g, but in order to do so I had to downgrade my bootloader to .76. I would like to restore my stock ROM using my nandroid backup, but it fails to load the boot image. Apparently this is because of a version mismatch?
Does anyone have the stock PC36IMG.zip file that I can download so I can restore the stock ROM?
Thanks!

Not sure if you really want the stock rom with all your settings back, or just want to go back to sense UI, but if it's the latter, here's the rooted stock rom to flash:

I would like to get the stock rom with all my settings/apps back, but I suppose I could try your link as a fallback if it's not possible.

Revert back to 1.47.651.1 from 3.26.651.1

I (prematurely) update to the leaked version of the Android 2.2 release. I would like to revert back to 1.47.651.1 so I can install Cyanogen 6 Mod. I am fairly new to working with Android ROMs, but I have tried several things.
1.32.651.1 and .6 RUU's do not work. I get "ERROR [140]: Bootloader Version Error".
1.47.651.1's RUU, refuses to see the phone getting "ERROR [171]: USB Connection Error".
I tried multiple "update.zip" files to no avail. I constantly get "signature verification failed" when I try and revert back to these files (renamed as update.zip):
Supersonic_1.32.651.6_rooted.zip
Supersonic_1.32.651.1_rooted.zip
Evo-Froyo-2.2-Rooted-Stock-Odexed-netarchy-signed.zip
I've also tried PC36IMG.zip and receive a "Main Version Older. Update Failed" error.
Is there any way to revert back to 1.47/1.32.xx or am I stuck on this half-baked version of Android?
quite sure there is no root method for the ota update at the moment.
should have read the post saying to wait for root.
last but not least WRONG SECTION POST THIS IN Q AND A
ROFL 100th one today prob
This belongs in Q&A but...
Did you use the rooted or unrooted OTA update?
If you flashed the rooted version you're screwed until someone roots it.
If you flashed the unrooted version, just reboot into recovery and restore the nandroid I'm certain you made before flashing an updated ROM.
Here's another thread about this problem (also in Development)
Once on 2.2, no root...
If you flashed a rooted version of the latest leak I don't think you should have any problems...
I has Fresh 3.0b2 on my phone (based off of newest OTA, but rooted of course) and I just re-flashed the latest CM6 nightly

Just a heads up, for the sake of confusion. I think you got the rooted and unrooted mixed up....
If you flashed the rooted version, you should be able to restore. If you flashed the UNrooted version, you have to wait for a Root method to be found.
Why flash why are you not doing a nandroid when you flash bell cw ask u and then it restores it just the way it was u know like using ghost on a pc

except that nandroid or not, you flash the UNROOTED OTA you are screwed for now. your nandroid will be there, but it won't be doing much for you if we can't root the new OTA.
Sorry about the wrong section; I was reading under development and I didn't think to switch.
Now just out of plain curiosity, how come the stock RUU will not work? I understand it is a different bootloader version, but doesn't it just install over it?

It doesnt work because HTC is not ****ing retarded. If they allowed it to work, what would be the point of them fixing the exploits that allow root?
The last two OTAs have come with bootloaders that have a concept of a minimum version requirement. It's a method to avoid downgrading. Despite the old OTA being "stock" or "official" or whatever you want to call it, it's a lower version than the minimum your current bootloader requires, meaning it would be a downgrade.
Sorry man, you're gonna have to sit tight while some nice dev bails you out.
Thanks for explaining. I don't mind waiting, I under stood the risks. Only thing is that I didn't quite understand how this part of it worked. Thanks for the explanation.

I'd like to know that as well.
Permission denied when running flash_image through adb.
Does not seem to work on 2.2 FroYo OTA
So if you flashed a rooted rom you can just revert with a NAND backup. Are there any other ways to revert back to a previous version?
Also lets say you go from the currently 2.2 roms back to 1.47, can you then turn around and revert to stock?

If you are rooted, you can do whatever. You can find a zip file of the original rom and just flash it from recovery. I'm not sure if it is possible to downgrade your radios when (I've never tried), but it probably is.

The stock 2.2 rom removes the custom recovery, so you cant use nandroid to revert.

This is why you use the rooted ones posted on XDA.

Stock Rom

Well Im having problems with my current rom and i would like to go back to the stock rom. Now I went here http://forum.xda-developers.com/showthread.php?t=685835 and tried the .exe and the zip but none of them work. Im currently using MIUI V 12.3 final. Since that thread is more than 6 months old there has to be some other ways. This is killing me any help would be great.
Do you want to keep root? If not, just run one of the recent ruu's.
If you do want to keep root, just download the sprint lovers rom, and follow the instructions in the thread. It's that simple.
Does anybody use nandroid anymore?
Always nandroid the stock rom after its rooted and has a custom recovery.

i actually had 3 or 4 back ups of the original rooted stock but when i went to restore of them they werent there. I either deleted by accident or something else happens. i always back up my roms.
which ruu should i use? preferably to unroot

Now, this is a simple question, but I'm not going to flame. If you want to UNroot then this is what you want (this is the most current 3.70.651.1 software)

How do I back up my stock recovery?

US Cellular has been promising Froyo for the CDMA Desire since October, and I'm tired of waiting so I'm going to root it and flash a Froyo ROM myself. I read through the unrEVOked documentation, and it mentions that if I want to install official updates in the future I need to restore the recovery image, but it doesn't tell me how to get it. How do I pull the stock recovery image from my phone so that I can flash it back on should I need to?
You can't actually backup a whole rom without rooting first. You need the custom recovery to do a nandroid backup which will back up the whole rom. If anything does go wrong or you need to reinstall then you can just use an RUU to do it. US Cellular doesn't have an RUU yet but you can use other CDMA RUU's.
So am I to understand that there is no way to back up the stock recovery, as I would have to overwrite the existing recovery just to do backups in the first place?
Yep, root access is needed to back the whole ROM up
To be honest, it's better with root anyway and a lot better when you install a custom rom.... from my experience anyway.

Thanks alot. Just what i wanted
Actually i have just thought about this and it does not include the zip. So this will not do the job.
Stock modules are in the stock nandroid (or ruu) these stock boot.img files fit the stock HTC modules. Modules are restored when a stock nandroid backup is restored
The stock 3.20.401 from Mike's thread is fully stock only in a custom rom install way. Only thing after the rom install that is not stock is the recovery.
So basically ive got to restore a Nandroid backup to do this?
Actually im guessing what you really want, you ask for the latest stock kernel. What's your goal with that ?
A custom rom has in 99% a tweaked kernel. A nandroid backup has stock modules + boot.img
So maybe you can point out what your goal is and i can give you the answer to that
Currently i am on Stock rom which is rooted. I basically want the phone in shape ready to receive any OTA that might come out in the near future. Im keeping root with the voodoo rootkeeper.
Ah oke and you flashed a custom kernel on it ?
Yeah i flashed the Tegra 4 one. Gotta say really good kernel, slightly disliked what it did to the screen though.
The easiest way to go back to full stock (modules + kernel) is indeed to restore the stock nandroid. Then its all stock, flash the stock recovery and you are also able to update official ota's (like upcoming sense 5)
Okay thanks a lot for that. Can't wait for that Sense 5 beauty, tried it on the One and certainly an improvement on the very good Sense 4.
Well i used an old Nandroid i had 3.14 software, factory reset, dalvik, then restored the nandroid. The Nandroid restored well except i was left with the kernel. Good thing is though the OTA still works as there is an update to 3.20
Ahhhh false alarm sorry. Me not thinking straight. -_-
The boot.img doesn't flash its self :L
Lol....solved ?
Yeah everything is good now thanks
Good :thumbup:
CASE CLOSED !

[Q] Unroot and get AT&T S3 back to stock

I rooted my phone then used CWM RomManager to make a backup image of the rooted stock rom. Then put KitKat on the phone. Since then I have restored the Rooted stock Rom. Now every time the phone boots I get the Upgrading Android message and the phone is kind of buggy. I am having trouble finding instructions anywhere on how to get it back to complete stock. If someone could point me in the right direction I would appreciate it.
Thanks
What stock AT&T rom were you running when you created the backup?
Oh I guess I should have mentioned that huh.. it was 4.3
Have you tried flashing the 4.3 update.zip file you can find in the developers forum here: http://forum.xda-developers.com/showthread.php?t=2387423.
I feel like you ought to be able to copy the 4.3 zip file to your SD Card and flash via recovery and it should work, although I haven't tried it so I can't be sure.
