[Q] TWRP help on Nabi 2 - Fuhu Nabi 2

I have a Nabi 2 that was rooted almost a year ago to gain access to the Google Play store.
My needs have changed since then and I wanted to restore it to factory settings.
The original root was performed by a friend that I am no longer in contact with.
If I boot normally the Nabi is stuck here:

I have managed to get it to boot to TRWP by pressing the power and + keys. I see this:
View attachment 2661206
There are no images to "restore" under the restore tab. This is what I see:

I am hoping someone can provide me with a kernel file or some tips on how to restore the machine to it's 'out-of-the-box' configuration.
I want to donate this device to a young child and need to get it back into a kid friendly mode.
Any help really appreciated.

after you get it going make a back up and STORE the back up on the pc would be my suggestion .

I think if I understand correctly, I should be able to restore the factory image using the restore function of TWRP.
In my case there is no backup there for me to utilize.
I put some files on a 16Gb sd card to see if the restore function would see them but it still shows up blank.
I checked the box that says "mount SD card" but I do not see the files.
I am sure it it something I am doing wrong.
I have posted pictures of what I see.....just in case I am not describing it correctly.
Thanks!

see if you have a system folder
in twrp -under mount, put a check in system
then back out of mount
now click on Advanced/file manager/
Scroll down to Sytem - tap it to enter it .
IF you can see that its still in tact then try factory reset
Factory Reset is under the WIPE menu .

I found the folder SYSTEM and clicked on it.
I do not see any files on the right side and I only another folder called LOST+FOUND on the left side.
If I enter LOST+FOUND I also see no files on the right.
Can I copy the required files into the SYSTEM folder from a SD Card?

in Twrp restore you can pick just system to restore
just make sure that "SYSTEM' is the only thing with a checkmark

When you say use TWRP RESTORE you are talking about the button on the home screen labeled RESTORE right?
If I go into RESTORE as described above I have the option of using EXTERNAL SD or INTERNAL STORAGE.
No matter which I choose there is nothing showing up in the PACKAGE TO RESTORE area.
The last picture in my original post shows exactly what I see when I go into RESTORE.
It is like the a backup was never done or somehow got erased.
Any ideas?
Thanks Eric

what I was saying is that if you download something from the wiki like 1937 put that TWRP back up on your External SD card inside of the TWRP folder
then use the Restore function in TWTP.
it will show up along with data boot system etc.
you can just Restore system .
use your pc. place the back up on ext sd card .when finished place the external sdcard back in to nabi.
then boot in to twrp /use Restore and you should see it.(just checkmark system ) swipe to do the function
exit and reboot nabi

I am sorry I sound like such a tool. A lot of this stuff is very unfamiliar territory for me.
Here is where I at:
I downloaded 1937stock.zip
I placed a copy on the SD card and copied that to the SYSTEM folder.
Went into RESTORE and did not see anything pop up.
Then I unzipped the file and copied those individual files to the SYSTEM folder and the same result.
Then I looked at your post again and it said put it in the TWRP folder.
Where is the TWRP folder? Should it be in the root folder?
The only place I saw a TWRP folder is within another folder called SDCARD. That folder can be seen from the root folder. However the contents of that folder change depending on what mount options are selected.
I am a little confused here about mounting and the folders named EXTERNAL_SDCARD and SDCARD.
Can you enlighten me a little on the difference between these two?
Should the 1937stock.zip file remain zipped or do I have to break the files out individually when restoring them?
And finally where should the TWRP folder you mentioned be located?
Thanks!

Think of Twrp restore function as a windows restore point
think of internal sd as widows primary hard drive(main OS is here)
think of External sd as a windows hard drive 2
you do not want to copy anything to system. you want to let TWRP do it for you .
1st thing you want to do is Extract the zip to the pc desktop in its own folder
then take the folder from the desktop and place it on the External sd card
then place the EXT.sd card in to the nabi2
Boot nabi in to twrp
click on Restore
here is a example of how it should look on the External sd
/twrp/backup/FOLDER TO RESTORE HERE
if you look in restore you will see the option for twrp to look at internal or xternal sd card for the back up .

I did exactly as you spelled out above. Unzipped 1937stock and put the files in a folder on the SD card that looked like this /twrp/backup
I verified the contents of the SD card while in my PC. It had 9 files in it. 2 boot* files, 2 data* files, 3 recovery* files and 2 system* files.
I put the SD card in the Nabi, made sure SD card was mounted and again verified contents of EXTERNAL_SDCARD with File Manager.
The files were all visible with the File Manager.
When I go to RESTORE it still shows up blank. If I click either internal or external storage, it makes no difference.
It is almost though RESTORE is looking for the files in a completely different path.
The only options in the RESTORE function are the sort buttons on the bottom of the screen and the two radio buttons on the top for internal or external storage.
Can I move the folder from the SD card to internal storage?
Would it make a difference?
What is the default path TWRP uses if internal storage is selected?
Or is the box on RESTORE screen supposed to populate with a tree that I can navigate to a specific folder?
For me it is just plain blank no matter what I press.
Similar to the picture in my first post.
Your instructions seem pretty straight forward. I double checked my steps but no dice.
Any ideas?
Thanks

lets try this
check an make sure that the External SD card is formatted in fat32
you can use the pc to do this
now place the External SDcard back in to the nabi
boot in to Twrp and choose the BACKUP function make sure that it is going make the backup to the external s card.
(the goal is to see if twrp is working)
IF this works then you should see a new TWRP folder on the external SD card
now go back in to RESTORE to see if you can see the back up you just made to your External sd card.
ps: yes you can move the TWRP folder to the internal sdcard if you wanted
Twrp will work from both Sdcards

Ok you are 'da' man....good plan of attack.
I formatted the card, fat 32, just to be sure.
Put card in Nabi booted and mounted SD Card
Ran backup and it did create files on the card.
It also created a timestamped folder
I assume you want me to replace all those files with the file from the stock zip package correct?
I did replace all the files in that backup folder with the files from the stock package in preparation.
I do not want to proceed until you let me know if I can pull that trigger.
I am only committing the SYSTEM files?
Do I leave DATA & BOOT unchecked?
Does this process remove TWRP and make it completely stock? That was my goal.
If I do get back to stock will I then be able to participate with the regular OTA updates that I read will bring the Google Play store on the device natively?
Thanks for your continued and rather quick responses! :highfive:

1st I would want you to keep a copy of that back up you just made on your pc <just incase we need something from it in the future>
Also keep it on the SDCARD
on your pc find that TWRP folder you just made
and add the folder you first tried to it
Example TWRP/BACKUP/BACK UP UP I MADE
TWRP/BACKUP/The one I downloaded
put card back in nabi boot to twrp
go in Restore and look for "the one I diownloaded" folder
uncheck all except system
swipe for the function to work
then it should ask you to REboot
Fingers crossed GOOD luck ..lol
Edit We will want it to update by its self
As of now you have a ICS(ice cream sandwich version of android) Currently we are up to jellybean 4.1.1
the tricky part for me was going from ICS to JB because I had missing Files that it wanted to update
also the Boot and Recovery is Diffent between the 2.

Dude your killing me....I did what you said above and rebooted and BOOM!
IT WORKS AGAIN!
It went through the OUT OF THE BOX setup. Yes!!!......BUT there is one big problem.
It will not see my wifi card.
If I try to turn on wifi via the nabi control panel it just stays off. The on screen switch appears to work but if I navigate to another screen and then back the switch is marked OFF again. No AP's show up in the access list.
Do I have to install a patch?
I noticed that TWRP is still installed.
And Thank you a million times over for getting me to this point!

before We mess with the wifi - some things to try
Are you broadcasting SSID? Wifi protected set up ?
Un power your router wait 1 minute then Repower it.
If that's not it then
Reboot in to TWRP
go in to wipe
only wipe*
cache and dalvik cache -* Nothing Else *.
Reboot nabi

No success. I have a number of AP's beside my own in this area that I can usually see.
I even turned on the hotspot on my phone and placed it very close and it could not pick that up either.
The on screen wifi switch behavior is still the same.
Did the two cache wipe things as well and no luck.
Should I have chosen a different stock***.zip? I see the Wiki has about 10 different flavors under the STOCK section.

Sorry man, no dice
It is doing the same thing. When you go to switch the radio on, a dialogue box come up that says "Please wait while loading", with a round swirly thing spinning. It looks like it is trying to initialize something but when the dialogue box closes I don't see AP's. Funny thing is the bluetooth radio switch stays on while the wifi switch will not.

ok Reboot to TWRP
go to mount
choose data - then back out
go in to Advanced/filemanager
then click on data then misc
then go to wifi
on the right you will see wpa_supplicant.config
tap it
on next screen choose Rename File
on next screen type .bak
so it looks like this
wpa_supplicant.config.bak
hit enter on the screen keyboard
next screen
Swipe to confirm
Reboot the nabi .
check to see if wifi works
