The topic says it all, is there a way to verify the integrity of the nandroid backups we make? Sometimes after doing nandroid backup and I have to come back to restore it, i find out that the backup is corrupt or faulty and the nandroid backup wont work. Either it will hang in the restoring process where the little dots "..." keep going or it says cant restore or something
I think with Clockworkmod recovery will give you an MD5 sum for every back up, not a 100% sure tho.

Can anyone confirm? Is there a way to verify if we're using amon's 1701?
A MD5 sum is only going to help provide integrity that the FILE contents haven't changed since you did the MD5 hash of the backup...this doesn't actually verify that the backup will restore properly.
I too wondered this same thing as i've had backups that wouldn't restore.

You can always try to restore the nandroid before doing anything else. I guess the catch may be that if it does fail, who knows what state your phone might be in. What about backing up twice and comparing the md5sum?
You probably have a bad sd card.
I go back and forth between cm6 and 2.1, and I have messed something up. I was going from cm6 to 2.1, wiped my data and cache, and went to restore, but accidentally hit backup instead. My phone acted like it was backing something up, and when it was finished I wiped again and tried to restore my 2.1 nandroid. It said there is an md5 mismatch. Restored my cm6, which worked fine, then wiped again and tried to restore my 2.1 nandroid and got the same mismatch message. Could it be because I did a backup after I wiped, or could there be another reason? That nandroid worked great until now. Many thanks in advance.

Did you change the name of the folder in which the Nandroid backup was stored? If so, revert it and try.
If not, you could generate the md5 and try restoring, but I would not recommend doing that.
Ok so i had an issue with flashing a theme so i had to restore my nandroid backup. The backup took quite a long time (i backed this up about a week ago). Now when im tried to restore, everything was going fine but now its stuck at this:
ClockworkMod Recovery v2.5.1.3 - Voodoo lagfix
Checking MD5 sums...
Restoring system...
Restoring data...
databases
It's been stuck there for a loooooong time.. Anyone know whats up?
Hey guys,
I used odin to get boot it back up and then I used ClockworkMod to restore backed up data....
After phone said 'restore complete,' I let the phone reboot, but the phone will not reboot
at&t screen pops up and then black out then pops up again then into android recovery mode.
Any ideas?
Could you please provide a little more information about how you got to where you are? (e.g. what rom/kernel/modem/theme you were flashing, what ODIN you used, what version of CWM, etc.) Anything you provide will be helpful in troubleshooting.
Well I had cognitive 4.5.3 installed and I tried restoring using clockmod recovery
the restore wasn't successful and the phone would stay black screened after Galaxy S logo screen
So I turned on odin3 and put my phone on download mode then hit start on odin3
that successfully restored the phone to froyo 2.2 without any of my data
so I tried using clockmod recovery once again to restore the backup
and then... that's where I am
The phone won't boot. It will just go into recovery mode
Here's the message I got after trying to restore once again
--------------------------------
ClockworkMod Recovery v2.5.1.2

When did you make that nandroid backup? If you made it while on stock, you'll have to go back to stock first, then run the restore command. If on cognition, you'll need to be on the version you were on when you made the backup and restore there.
Here's the link I found on how to return to stock rom

I've done the first part - before the master reset and then tried restoring the backup and that is how I got to where I am right now.
Do I need to factory reset as well?
If I do factory reset, won't that erase the backup file?
Thanks. I really appreciate your help

To answer your question, doing the master clear will erase EVERYTHING stored in the phone's internal memory. Don't do that step now, as you should be able to get out of where you are without doing that.
I think where your problem occurred is that at some point you made a nandroid backup in CWM, and by trying to restore that on stock, it's freaking out. If you can remember what ROM setup you had on your phone when you made the backup, you could try to get back to that setup to use the restore option in CWM.
Before doing any of the things you're doing now, had you made a backup in Titanium Backup?
I do have backup made with Titanium Backup.
apps data and everything that I could backup with Titanium Backup
Will restoring what I had backed up with Titanium Backup and then restoring the system using CWM work?
I am currently at 2.2 Froyo, which was the rom I was using when backing up using CWM
You've flashed 2.2 stock? If so just flash the rom you previously had with cwm then let it boot. After it boots reboot into cwm then perform a restore in cwm. If that doesnt work nand backup might not be good and you will just have to flash stock again and just rub tibu and leave it at that.
**Thing about NAND backups is that you have to use the same system when you restore (i.e. you nand backup usng cognition then you flash another rom when you nand restore its not going to boot).
Thanks guys for the suggestions!
My phone has been saved!
hi,
I did a nandroid backup of my phone when it was stock, just rooted. And i tried to restore it yesterday but not sucessfully. It says "md5 dissmiss" or something like that.
It worked before, just after i had made it.
can i fix it somehow?
