Question guys. I'm trying to restore a nandroid backup and keep getting the md5 checksum mismatch error. I have a few nandroids that work at the moment. I know this is a stupid question but I thought worth a try. If I replace the files from the nandroid backup that gets the md5 error and move all the files over to a nandroid thats working, is this possible? The only file I won't be replacing is the nandroid.md5 file. I've moved the boot, cache.ext4, data.ext4, system.ext4 files that I would like to restore. Thanks in advance guys!
Please close thread. Got it fixed!

Actually if you're trying to restore a backup and get that md5 mismatch error it usually means that there is characters in the backup's folder name that it won't recognize, try renaming the backup folder name with no spaces or hyphens, I usually only use letters and numbers with no spaces, try that and it should be ok at that point...
EDIT: Also I don't recommend moving the files into a working backup folder as the md5sum is generated for each specific backup and you could have problems if the md5sum doesn't match the files that they were created for...

I renamed the folder to abcdef123 and tried restoring the ICS backup (downloaded from a thread here) thru CWM but same result.. md5 mismatch.
I restore GB backup but it gets restored everytime.
Also i have checked the md5 checksum of each file thru a pc software.. and they are correct.. same as calculated by s/w
problem lies smwhere else..!?!?!?!?!?!???
does any1 knows some other location of ICS backup other that this http://forum.xda-developers.com/showthread.php?t=1888536

When I try to restore certain backups in CWR it says MD5 mismatch. Wat causes thus? It seems to be the name.
Note: I'm not altering the number sequence. Just adding to the end.
Is it cuz I use numbers or wat?

I had a few instances of this happening before and when I opened the .md5 file located in the nandroid backup folder and actually ran the md5sum myself I got a mismatch. I don't recommend changing the .md5 file to the correct md5sum.
To check it yourself, use terminal:
Code:
cd /sdcard/clockworkmod/backup/<path to nandroid>/
cat nandroid.md5
md5sum *.img
There you can see if there are discrepancies.
Awesome. This forum's become soooo essential to me. Tundra 4the help.

Im having the same issue. If i rename a backup in RM and then try to reflash it, I always get MD5 mismatch. So whats the solution?
yo, i found a solution that worked for me:
just rename the the folder to its original tittle fx. "2011-06-30.15.21.11"
and then try restore again !
MD5 checks the integrity of the entire file.....you change something (even the name of the folder) and the MD5 checksum will fail.....I never rename my nandroids, nor any .zips I flash....I've never downloaded anything from here that was named in such a way that I wouldn't know what it was....

I'm calling foul on this one. I have renamed my folders for over a year without issue. Only had one problem recently with updating to CM7 on DroidX (using new 2nd init recovery). As long as there are no spaces in the folder name it works fine.
Read somewhere before that not enough space on your sd card may cause MD5 errors. I always thought recovery might have to 'unpack' the files somewhere to restore and if there's not enough space then it would produce an error. I have not tested this out myself.
md5's are stored for each .img not for the entire folder. As someone else said, I've been renaming backups for about 18 months on devices. As long as you don't include spaces (if renamed with RM it should warn you of this) you're fine. Chars like "- . _" are fine just no spaces.
I've got 3 CWM backups on the internal memory of my Samsung SG2.
I tried to restore one and it failed on md5 mismatch/error (or something to that effect...) - tried the others - all returned the same error, yet when I'd actually backed them up, they all completed successfully.
The one thing I did to them all, was give them a more recognisable name, rather than just the date & time so I knew which ROM they were...so out of interest, I backed up my existing (new) Cognito ROM while still in CWM, then when it had finished the back up, immediately tried to restore the newly backed up ROM....and it worked! Is it failing on the others because I've renamed the CWM backup folder?? I'm sure I've done this in the past on my old HTC Desire, and had no problems
Also, is there a way to rescue the backups I've done by generating a new md5 checksum for the renamed backups...or are they toast now??
Thanks for any help...

Google and you will find:
# cd /sdcard/clockworkmod/backup/2010-06-29.20.22.53 (Which is your clockwork mod backup folder)
# rm nandroid.md5
# md5sum *img > nandroid.md5
Do this from a terminal emulator or from adb...
Thanks karendar...but I'm afraid I'm a bit crap at adb and that kinda stuff
I've downloaded an emulator off the market and when I fire it up, I got a $ prompt; found out how to get # prompt but when I put all that in, it gives the following error:-
"md5sum: can't open '*Img': No such file or directory"
When I looked inside the backup folder, there are a series of img files so is the wildcard * is to be put for each file in the back up folder? (I tried one of them - the boot.img file in there, this time there was no error brought up....but I also never got any 'success' confirmation or anything
Help
(BTW....whenever I type the letter 'i' - it changes into a capital 'I' all the time... What's that all about??)
**Bump** anyone??
Rename your backups and make sure there are no spaces in the names. Or keep them to a maximum of one space.
That way there will be no problem with md5 mismatch.
Considering your issue with md5sum: turn off autocorrection in your keyboard settings, and then make sure the command you are typing is
Code:
md5sum *.img
Note that as Android is Linux, capitalisation matters, and *Img will return no results at all.
Thanks dude, i had the same problem on my P500, and your tip helped a lot!
Especially since my phone was stuck in a bootloop and my recoverys wouldnt work... You learn something every day!

Went to install a backup made with CWM today. This is the first time I've done a restore on this phone. Went to restore and am getting an MD5 mismatch on all 3 of my backups!
I have not moved the files or changed their names. They are right where CWM put them.
I've had trouble with the newer versions of CWM in the past that use the TAR files instead of an image file.
I deleted the MD5 file and through terminal did a md5sum *.* > nandroid.md5 to create a new MD5 file but it doesn't work. Is the *.* a proper way to wildcard all files in the directory under linux? Is this the correct way to do it or is it just one of the files I should be doing the MD5 for?
Thanks for the help!
Mike
Can't believe no one has an answer for this.
I did answer my question about the proper syntax for the MD5, it's: md5sum * > nandroid.md5 in case anyone wants to know.
I did finally get my phone to restore. I removed the RAZR bootstrap and reinstalled it and bang, it installed just fine.

Can you say exactly how you did it? Would be quite interested to know.
I backed up my rom with Clockworkmod v6.0.1.4 and when I went to restore it, it said md5 mismatch checksum. I checked in the advance restore options and it shows the default restore format is .DUP instead of .TAR so it saved it in the .dup format. Now, when I went to check up on the folder on my SDCARD it never showed an md5 file because it never created one. I read all of the " 20-second md5 fix " posts and I created an md5 file and made them blank off of a YouTube video and I also installed RapidCRC to attain md5 checksums from the img files in the backup folder to add to the new nandroid md5 file and out in the backup root folder and I even tried the SDCARD root, but to no avail, they all failed and I still get the md5 mismatch error. I have attached pictures that show my folders and files. I need some help on restoring please!

Dude, you don't need another thread for this....
Can I restore data that I have backed up in CWM form my device to another?
As long as the model is same, yes. What device exactly?
I don't think so, even if they're the same. i've done it once and the cwm log says 'md5sum mismatch!'

If you insist on restoring the backup file do this simple trick on md5 mismatch: open the md5 file in your CWM backup folder, erase its contents. Leave the file empty (0 byte) then restore in peace
Keep in mind md5 mismatch means something changed in the backup file, doesn't matter which device it previously on. Do this on your own risk.
Note: CWM will skip verifying the backup if md5 file is empty.
