Fix Nandroid MD5 Mismatch Woes

Creating a Nandroid backup is very highly recommended for any Android user looking to root and modify his or her phone. For the unfamiliar, Nandroid saves an image of every partition on your device to your SD card. When in trouble, you can simply restore a Nandroid backup in your custom recovery. Nandroids can thus solve numerous problems such as bad ROM flashes and bootloops, provided that you have a recent backup. So, what happens if a Nandroid backup you made, but never touched, reports an incorrect MD5 checksum signature? Panic, of course, but there may be a simple solution.

XDA Senior Member ihtfp69 writes about a simple hack that allows one to bypass the MD5 checksum error, and thus restore from a “corrupted” backup. The method itself is very simple. Users only need to have the Android SDK installed for ADB access. Then, it’s a couple of quick ADB commands and your Nandroid backup is usable again. Of course, this is not a method for everyone. Says ihtfp69:

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.

Removing the MD5 checksum on a truly corrupt backup can be hazardous to your phone. After all, we’ve written about the importance of checking MD5 checksums in the past. It is therefore advisable to only use this method if it’s a Nandroid if you know it is a valid backup because restoring a bad backup is like flashing a bad ROM. While the short guide was originally written for the HTC Droid Incredible, it should be compatible with any device running ClockworkMod Recovery.

PSA: You Can Optimize Your Note 4’s Recents Menu & RAM

The Note 4 never had the fastest Recents Menu, and despite its 3GB of RAM, its app-holding capabilities only got worse on Lollipop. The infamous RAM bug that plagued the S6 is indeed an annoyance on the Note 4's 5.0.X ROMs. Rumors of an update to fix all of this were confirmed with the first reports of the 5.1.1 update for the Russian Note 4, which seemingly improved the Recents Menu and RAM management. But it'll be a long time...
