Hi guys,
I have a technical question and i wish to get a pure technical answer. Why is it that when you restore a Nandroid backup, the restored version is not rooted. Isn't the backup done on a rooted version? Thanks.

If you backup a rooted rom, then restore the nandroid it will be rooted
well not according to the Australian Stock Rom Thread posted by Kazuroka

The ROM they are discussing in that thread is not rooted, certainly when I restore my nandroid backup, currently running cm7, I still have root

It is possible to generate nandroid backups of unrooted ROMs, just not all that common. For example if you have previously applied ENG HBOOT, you could flash custom recovery from fastboot without actually re-rooting the ROM. The resulting nandroid backup will not have root.

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.

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.

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.
Hi, I have stupidly flashed a ROM without backing up the stock ROM. I am hoping someone could forward me to the correct Stock o2 rom or point me to a stock nandroid backup. I cannot find other posts hosting the Stock o2 ROM or any backups (sorry)
Thank you very much, it was a lesson well learned

The best way to do that is by following torxx tutorial from this thread in section If you DON'T have custom rom or Nandroid backup on internal SD card
Hope this help

Hey,
Xperia M dual user here. Recently got the update to 4.3 Jelly Bean. I updated and of course lost the root. Now, I took a backup TA when I was rooted in 4.2.2. I am going to install CWM and try some custom roms. So can I still use the same BackupTA or do I have to create a new one after I upgraded to 4.3?
Thanks!

If you have taken a backup in 4.2.2 then restore it in 4.2.2 only to relock the bootloader and then upgrade to 4.3. Then take backup of ta again then do whatever you to do with your mobile.

Just for clarification, so I can only relock my bootloader in 4.2.2 because I took my BackupTA on 4.2.2. I will not be able to relock my bootloader in 4.3 with the BackupTA took in 4.2.2. Did I get it right?
Also, the problem is 4.3 doesn't have any rooting method without unlocking bootloader. I have to take a backupTA before unlocking for which I need root. So kind of in a catch 22 situation here.

Well that's what I had read somewhere. Not sure where exactly. Its always preferable to restore TA Backup on the same version which it was backed up.

You are wrong mate. There is a working method to root 4.3 without unlocking Bootloader but that requires you to be in 4.2.2 + Fully rooted + locked Bootloader + Access to Windows PC along with USB Cables and Drivers.
Search In Android Development Section. The current version for the mod is v1.2
Although not recommended, you can restore your TA backup in any firmware version. Sometimes when you restore a backup taken in an old firmware version you get a bootloop that can be easily fixed by flashing the stock kernel again with FlashTool...
I'm saying that because I did something similar: before developing Nicki Root, I took a TA backup in rooted 4.2.2, unlocked bootloader, flashed 4.3 and rooted it by using CWM and then I restored TA backup I took in 4.2.2 and everything worked fine. I already did this procedure at least 5 times and it worked all of them, the only attempt I got a bootloop was after restoring TA backup while running a custom kernel, fixed by flashing stock kernel again
Another tip: create a TA backup with bootloader already unlocked too, if you ever need to unlock it again you can simply restore that backup, without needing to use fastboot and without wiping data partition

Hey that's a great idea! The phone will not reset at all.
You can restore your TA backup in any firmware as long as it is stock rom

Ah, I see. Thanks a lot guys!
You can restore it in any stock rom with stock kernel. I have restore ta 4.1 to 4.3 many times without problems

If this backup really doesn't have root, then yes I believe that would technically unroot it as far as the OS is concerned. You would still have a custom recovery unless you restored that to stock. May I ask why you were doing this?
