Default [Q] TWRP help on 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:

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.

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 .

Thanks for your help...
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 .
