Restore is the “comfort food” of mod’ers!
If is much easier to “take a chance” and try modifying your Nook, if you know that you can return to your present setup if something goes wrong with the new stuff. That is what a Nandroid backup/restore does – take you back to exactly where you were when the backup was done.
Instructions for Restoring a backup on the Nook Tablet.
There are three possible scenarios for getting CWM to run on the Nook:
- Executed via external (bootable) SDCard
- Executed via internally installed version
- Executed via Cyanoboot (2nd boot) program
If you do not have CWM installed on the Nook’s internal memory (or, if you do not know), then you should use the External (bootable) SDCard version. (Instructions for creating it are here.) In this case, you should just insert the bootable card into the Nook’s SDCard slot and power the Nook on (press the power button briefly). When it boots into the Blue menu, skip to “Using CWM”.
If you have installed CWM to the internal memory of your Nook, execute the program by pressing the Nook (or home) button and the power button at the same time. Continue to hold both until the screen begins to display. At this point, skip to “Using CWM.”
If you have Cyanoboot installed (with CWM as the internal recovery), then execute the program by pressing the power button, then when prompted, hold the HOME button. When the Cyanoboot menu comes up, use the Home key to move down the list and find “Internal eMMC Recovery” then press the power button to select it.
- Let CWM boot completely (displays blue menu)
- Insert (or switch) SDCard in slot on Nook (the card must contain your backup files)
- On the CWM menu, select “backup and restore“
- Select “restore“
- Locate and select your backup from the files on the SDCard & press the Nook button to select it
- Answer “Yes” to the confirmation item.
- Wait until CWM returns to the blue menu.
- Remove the SDCard from the Nook
- Select “reboot system now“
That’s it! If there was no error reported, then you just restore your Nook’s internal memory to the same position it was when you did the backup. All the system info (Rom, settings, etc), applications, and internal user data were restored and the Nook is returned to exactly the same setup as when you made the backup.
