[How To] Fix md5 mismatch nandroid restore

---

I figured I would post this fix here in case anyone else ran into this problem. This is assuming you did not change the folder names and let Clockworkmod create them. I haven't had it happen until today, but it's not a nice message to see when you are trying to do a restore.

Checking MD5 sums...
MD5 mismatch!

To fix this problem use the code below. Substitute the final folder name for the backup you need to fix.

adb shell
# cd /sdcard/clockworkmod/backup/2010-06-29.20.22.53
# rm nandroid.md5
# md5sum *img > nandroid.md5

When that finishes, re-run the restore and everything should be fine.

NOTE: As rpearl stated, there could be something really wrong with your nandroid, so use this tutorial as a learning experience and not a fix-all. In my case, everything was fine after restoring. However, that may not always be the case. Do this with caution.

I had a md5 mismatch and was freaking out. Turned out that the folder name for my backup couldn't have spaces in it...

This also works for anyone that wants a to make a 100% stock image but keep recovery.

just replace the boot.img and system.img with the ones from the RUU and recalc.

i just got this problem. do i need the "#" for each command?

Any idea what causes this? Is it just the folder name with spaces?

No the # simply means you are logged in as root or Su

If its showing $ then you may need to type /system/bin/Su

I believe or could be /system/lib/su I'm still pretty new to Linux / Android

Spaces aren't allowed but it could also be caused by corrupted data or sometimes even simply renaming the folder

Be warned: If the nandroid was legit broken, then this will restore it *anyways* and your system won't boot / will have weird errors / whatever was wrong with the nandroid will be wrong with your system now.

Obviously you can just restore a previous nandroid if that happens.

i did this and still cant fix the md5. making me to use the older backup

For n00bs could you elaborate on this post, i'm having the same problem.

"To fix this problem use the code below"

I know this is through cmd, but what needs to be where when i'm typing exactly that in (changing the folder name etc) what screen do I need to be on. If it was more detailed, and thank you so far because this is the only post on the net, it could be very useful!
