I had a number of requests for tutorial Nook Touch describing how to restore a rooted nook Touch to its factory default state. I’ll describe a number of methods to be used based on the gravity of the issue. If the Nook Touch still works well, you might need the quick procedure. If it is bricked, you probably need to take the more drastic measures including a complete firmware re-flash. Let’s proceed!
Note: this article, at least for the firmware re-flash part requires you to be familiar with this procedure. If you rooted your device, you probably are. However, a quick read into our initial How to root Nook Touch article might help.
Restore Nook Touch Method 1: interrupt the booting process 8 times
Step 1: Power off the Nook Touch.
Step 2: Power it on again.Step 3: Long press the power button as soon as your Nook Touch starts booting (and you see the starting message) to stop it forcibly. If it doesn’t want to start anymore, try Home + Power buttons pressed simultaneously (a kind of forced reset)
Step 4: Go to step 2 again and repeat the whole sequence 8 times.
Step 1: Power off your Nook Touch
Step 2: Power it up again. When the boot message appears, push and hold down for several (5) seconds the left and right page buttons on the bottom. The Nook Touch will then display a message asking you to perform a system wipe. If you still want to do it, click Home two times. The whole step might take up to several minutes.
Restore Nook Touch Method three: Flashing the initial firmware
This is the most effective way to restore your Nook Touch, the only problem is that it requires you to be pro-active. That means you need to backup it before you start playing with it so you have a clean firmware backup. You can use the backup method described here. Make sure, as the original article suggests that your back-up file resulted is 1958739968 bytes long.
Once you have a backup of your own firmware, you can use the same process as when you root it to restore the firmware back on your Nook Touch using Win32DiskImager for Windows. You’ll also need the MiniTool partition Wizard to erase all the Nook Touch partitions prior of using the Win32DiskImager.
Method 4: In case everything else fails. Wait until B&N issues a firmware update which will override your rooted Nook Touch. This will of course work only if your Nook Touch is still usable.
