Method 1

First try this!

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

Method 2 :

If Method 1 doesn't work try this way! Hard way - manually setting MD5 values!

Download this > MD5 Calculator

  • Manually go through all the files in the backup folder and calculate MD5 vals, Add them into nandroid.md5 file
