I think I may have finally fixed this (though I don't really know the cause). If you have the issue, please try the following: Download the latest ROM Manager off the Market: 126.96.36.199 currently. Start the application. Flash Legacy Recovery. Choose 188.8.131.52. This is the recovery with the fix, it is a test recovery, so it isn't flashed by default. Try a backup Then test a restore of that backup! Please let me know if this fixes the missing md5 problem. Been trying to track down this bug for a while!
