[Fuhu Nabi 2] aicjofs:
9. Recovering Bricked Devices

​

In this section we will go over recovery from non booting devices. I would classify non booting as one of three situations.

1) Tablet is being used normally and one day it has crashed or when restarted sits at the bootamination(spinning Nabi logo, Dreamworks characters)

If you haven't been doing anything but using the tablet normally then the most likely culprit is that some file is corrupt on the data partition. While there are ways to replace just that file if you suspect which one it is the simple solution is to try and wipe the data partition and start fresh. There are two ways to accomplish this:

a) Use the stock recovery if you haven't installed TWRP or haven't unlocked the bootloader. Boot the stock recovery using "recovery" in Section 3 above. Press both vol+ and vol - and the same time and you should get a menu where you can select to factory reset. This wipes ALL data from the tablet. When complete try to boot the tablet.

b) Use TWRP recovery from section 7 above. TWRP will give you some flexibility in that you can back up the data partition before you wipe it(in case the issue wasn't actually the data partition you can restore the data back), and TWRP will not delete "internal storage" if you do a factory reset.

-Boot TWRP

-<optional> Backup data partition to EXTERNAL sdcard(be safe and back up to external card not internal)

-<optional> While connected to computer backup the remaining files on the "internal sd" with windows explorer(Device should show up as an MTP device on later TWRP versions)

-Select Wipe tab and factory reset

2) You have installed a mod, installed a root application that has made a system modification, installed a zip file, or were just playing around swiping and wiping things in TWRP. Sometimes this will appear the same as above with a bootloop and boot animation that goes on forever.

a) Download the ROM for your device in section 10

b) Boot to TWRP (see above for instructions)

c) Do a backup of just the boot partition in TWRP.

- Click Backup tab

- Just check "boot" and nothing else.

- Swipe to Backup

d) Eject the external SD from the tablet and place in the computer

- Note: You should unmount the card from the mount tab in TWRP before ejecting it. (Uncheck the box next to external SD)

e) Connect the SD card to you computer

f) On the SD card navigate to the folder TWRP/BACKUPS/XXXX. XXX is a serial number unique to your Nabi.

g) Make a new folder and call in whatever you want. So it should now look like TWRP/BACKUPS/XXX/yourfolder

h) Unzip the ROM file you downloaded in to the "yourfolder" you created above. The files should look like ext4.system.win, emmc.boot.win, ext.addon.win, etc. Inside the the "yourfolder" directory.

i) Download the bootloader zip for your device from section 10

j) Copy it to the external SD in a location you will remember. This will be for the bootloader update.

k) Eject the SD card from your computer (safely eject it)

l) Install SD card in Nabi

- After inserted in tablet go to TWRP mount tab and check the box to mount the SD card

m) Go to restore tab, and find the backup under the "yourfolder" you made and unzipped the files to.

n) You should be able to select boot, system, and addon and skip the others.

o) If everything restores then go to TWRP install tab, find the bootloader.zip you downloaded and install it.

p) Reboot
