The recovery log would be useful

With TWRP booted

adb pull /cache/recovery/log

adb pull /cache/recovery/last_log

Also you could get some bootloader information with nvflash. You could use NabiLab2015 in US mode. Click expert.

Boot the Nabi to bootloader screen and select forced recovery. Screen will be black. If you look in device manager you will need APX interface installed. If not you will need to install it. The driver and shortcut to device manager should be available in Nabilab screen, and you may have to deal with Windows driver enforcement if you are on 64bit.

You can only perform one action at a time. So boot the Nabi to force recovery and "Get partition table". See how many partitions you have. Power off the Nabi and go in to forced recovery again. Now pick the bricksafe for 18 or 19(whichever you found out from "Get partitions". Avoid the urge to flash bootloader in that screen hahaha.

Now on main Nabilab screen you have "manual file" click that and go to nvflash folder and get the Nabinvflashbackup.zip. That file and the TWRP logs will give me a better understanding hopefully.

EDIT: See attached picture. I just installed UK 2.3.2 on US Nabi2 with the US KK bootloader. I used TWRP 2.8.5 for Jellybean.
[Fuhu Nabi 2] Aytul:
I think we have some success! I wasnt able to do install the rom (link to 2.2 & bootloader). The SD card was being picked but when in restore, the file I added wasn't showing. I copied that to the device and ran the recovery that way. I then installed the bootloader, wiped the cache and bingo it has loaded!

Now lol, I have tried this on the second device, but the restore option isn't showing me any of the TWRP backup folders (SD or the folder copied to internal memory)..any ideas?
[Fuhu Nabi 2] aicjofs:
Usually that is the because TWRP switched the way it gets the serial number to name a backup folder.

So you have the path on external_sdcard as

TWRP/BACKUPS/XXXXX/SOMEFOLDER where XXXXX is the serial number. TWRP only looks in the folder XXXX that it believes is the serial number for the device. This is so you can move the SD card around to different devices and not be restoring the wrong backup to a different device.

This is why I recommend just making a backup of "boot" partition before you start. That way you know what TWRP thinks the serial number is. So I make a backup of just boot and then look on SDcard. Whatever path it created for XXXX, that's where I make a folder, and in that folder put in the system.win, addon.win, boot.win.

So if you are sure the file is on the SDcard but not showing in TWRP that is usually the cause. There other thing that can happen is the info isn't up to date if you are hotswapping the SDcard. Make sure when you are insert or removing the SDcard to go to the mount tab in TWRP and click the box to mount or unmount. Sometimes just toggling the checkbox will refresh it, but it general you should be using that tab to cleanly mount or unmount.
[Fuhu Nabi 2] Aytul:
I tried the mount / unmount with no joy but the backup of boot worked :o). I hit a stumbling block as it wasnt loading again so I am re-installing the UK stock software..I'll let you know if this finally works for both!! One last thing, the 1 device I am now running is running out of space. How do I remove TWRP? I don't have the stockunrooted file
[Fuhu Nabi 2] aicjofs:
TWRP removal won't save you any space it's on it's own partition, nor will remove anything on system. Inspect your internal SD card. You must have large files there, or app data is filling up. The data partition is where all the space you can free up is.
[Fuhu Nabi 2] Aytul:
When I looked into the storage it shows over 1.7 gb for TWRP under Misc

Update: I deleted the TWRP folder through TWRP itself, not sure how it got there but the folder was showing in the wrong place.

Still having issues with the 2nd device, I may need to send you the log files shortly. I don't have the drivers installed and am on 64bit..any advice please?
[Fuhu Nabi 2] ehscoto:
When I go into Device Manager what should I see to determine if the fastboot driver is installed?
[Fuhu Nabi 2] aicjofs:
Oh, gotcha. The TWRP backup folder. Yes it's safe to delete if you have everything you want out of the folder and on your computer.

Drivers for APX or something else? Google Windows driver signature enforcement

Depends on which driver you are using. Usually it's under Android Phone and will say "fastboot interface" or "bootloader interface" If it's not installed usually you see yellow exclamation point by "other devices"
[Fuhu Nabi 2] aicjofs:
Nice work, getting around driver signature enforcement is a nightmare.

Well I don't see anything in the logs that is a smoking gun. It looks like you have data completely wiped, and it seems like system and addon files are there.

Examining bootloader 04_EBT.img it looks like it is still US 3013 bootloader. This may answer our question if it can be downgraded by normal means. However I was able to load 2.3.2 on my US Nabi with the 3013bootloader and it boots fine to the UK ROM. I'm not sure that is an issue or not. We could use nvflash to put it back to the UK version I guess but I'm not sure if that's going to do anything.
[Fuhu Nabi 2] Aytul:
Ok, I guess we could give it a go? I'm not sure about the boot loader on my other device but following the same steps, it worked fine. The only time I had the hanging logo was after I loaded the UK install and before the bootloadet changes
[Fuhu Nabi 2] aicjofs:
Which backup did you restore on the second tablet? Both are the same backup right?

I'm going to upload what worked on my US tablet here for you to try. Will take about 30 min. Of course by that logic the US version of Kitkat should have worked for you...
[Fuhu Nabi 2] Aytul:
I went from UK to US without issue, and back again on the one tablet. But for some reason this tablet doesn't want to play ball. Let me know next steps when you're ready please
[Fuhu Nabi 2] ehscoto:
Ok, I was able to last night get the TWRP working again on the Nabi and was also able to update to a later version of TWRP. So another question I have is that I have another Nabi that is working, can I back up the files from that Nabi and place them in the backup folder in the serial number associated on the external SD card and then insert the SD card in the Nabi that I am trying to get working, and restore those files to get the Nabi working again?
[Fuhu Nabi 2] aicjofs:
Oops. I thought I posted the link. It's the same as before www.nabtabhacks.com/downloads/232UKstock.zip

Yes, that will work it most circumstances. You need to get boot, system, and addon backups, and restore them.
[Fuhu Nabi 2] Aytul:
Is this different to the previous UK Stock file you provided before? (Post no.43)? As this is what I have been restoring to on both devices
[Fuhu Nabi 2] aicjofs:
Yes it's different. I just used same url.
[Fuhu Nabi 2] Aytul:
I'm sure you've heard it before but you are a genius :) it only went and worked! Currently staring at the initialization screen..I can't imagine it not working from this point. Thank you very much for your help

What was the difference between the files?

PS. the wifi is now working on it too! how did that happen?!

PPS. the wifi has stopped working again..that must be a hardware issue? I was in the middle of downloading content when it just went off
[Fuhu Nabi 2] aicjofs:
The difference was making a backup of the working one here. It has the SElinux ext4 info. Shouldn't be a difference with the files themselves unless some how the other backup was corrupt somehow.

How long was the wifi working? Can the wifi be turned back on? Does it have a mac address when you check?
[Fuhu Nabi 2] Aytul:
It was working straightaway for about ten minutes, it suddenly just stopped so I restarted the device. It lets me toggle from Off to On but stays at 'wifi is turning on' but no MAC or IP address
[Fuhu Nabi 2] aicjofs:
Did you try deleting wpa_supplicant?

http://xdaforums.com/showpost.php?p=46212787&postcount=4

Shouldn't have happened at all but this would be quicker then a factory reset again.
[Fuhu Nabi 2] Aytul:
Yes, it didn't change anything still not working
[Fuhu Nabi 2] aicjofs:
Copy the one from other Nabi, or factory reset :/

This is worth the read too, especially the logcat to see if you have a parsing error, or whatever.

http://xdaforums.com/showpost.php?p=48542174&postcount=2
[Fuhu Nabi 2] Aytul:
I copied the file from the working device but with no joy. I've seen the other suggested post and will run through this late on today. Can you provide a little guidance on how to access the directories for entering command lines etc please?
[Fuhu Nabi 2] aicjofs:
In NabiLab2015 the "manual file" button opens windows explorer to the location of adb.exe and 2 adbwinxxx.dll's, you can copy those 3 files to a location of your choosing or use them where they are at. Right click while holding the shift button on the keyboard and click "open command window here". Obviously you have to have ADB setup on the Nabi in settings.

adb logcat -v long > Nabi.log

Then you can view the Nabi.log file.

There are some good Google store apps for example

https://play.google.com/store/apps/details?id=com.tortel.syslog&hl=en

https://play.google.com/store/apps/details?id=rs.pedjaapps.alogcatroot.app&hl=en

but without wifi you would have to download them on other tablet and sideload them.
[Fuhu Nabi 2] Aytul:
Hi, I managed to run the log but didnt really understand how to use the apps you've linked? I have them on the device but the aLogcat ROOT app shows a blank screen and the other app says to send the logs via email or skype (which I can't do without wifi). I tried running the cat command from command line but kept getting permission denied errors?

I have attached the screenshots for the log ran via your command line
[Fuhu Nabi 2] redriddick:
Hi Guys,

I have a question.I have a Nabi2 that is stock.A friend of mine borrowed it and now when I turn it on the andoid bot is lying down with the red triangle.

I have tried the recovery kernal and wiped the data but it is still the same.

My question is can I unbrick it?

It is not recognised in windows and the nabilab is not detecting it either???

WOuld appreciatre some help on this.

Regards,

Redriddick
[Fuhu Nabi 2] n3wt:
The good news is...there's a 99+% chance that you can unbrick it. The bad news...there really isn't any except that I'm not the one who can help you (probably). I can tell you that we need all the info you can give us so that someone can help you...like were you on the latest stock update? If not, which one? Can you get anyinfo from your friend about what happened? any and all of that kind of thing can/will help.
[Fuhu Nabi 2] redriddick:
Thnaks for the reply.I have just talked to him and he either does not know what he did or he is not telling me.

I am in Ireland if that helps and purchased it last christmas but I dont remember what stock update was on there.

Thanks again for the help.
[Fuhu Nabi 2] ehscoto:
Ok, so I have tried to use the back information from the Nabi that is currently working to the one that is not, and still I can not get past the logo screen. I have read a few post regarding the boot manager as well as the using Nabi PC Suite, which I can't find. So basically I have the latest TWRP and am able to flash the zip files, but none of the available files or any of the forum post seem to get me past the logo screen. I am at a complete lost and getting a lot of pressure from my wife to take it in to Best Buy to see if they can fix, so I am hoping someone can point me in another direction or give me another direction to search the forum. Any help is appreciated. Thanks.
[Fuhu Nabi 2] aicjofs:
Sorry I was on a weeks vacation. Make any progress with this? Try copying the wifi supplicant from the good tablet and setting permissions?

So is this a UK version or US version tablet?
[Fuhu Nabi 2] Aytul:
Nor phlegm, I hope you had a nice time :) Currently no, the copy of the file made no difference at all. I tried the logs (screenshots on my last post) but no progress currently
[Fuhu Nabi 2] redriddick:
Thanks its a UK one.

I cant get the pc to recognise it either.I have downloaded nabilab full and installed the drivers from there.I can get to the stock recovery ie fastboot and that menu.I also did a factory hard reset and nothing helped.
[Fuhu Nabi 2] aicjofs:
I saw the logcat. Not sure what's going on with it. Make backup of data, factory reset, and see if it works and how long, you could always go back to the tablet as it is now by restoring your data backup.

None of the automated tools really work with the UK version. You can swap UK files in to place of the US ones and get the tools to work. There is this which is the manual way also : http://xdaforums.com/showpost.php?p=50431606&postcount=98

im getting a blank screen when my kids nabi starts up

I feel really stupid for doing this because im not a pro when it comes to electronics, tablets, computers or whatever but I im not computer illiterate so I gave it a go and my luck I screwed something up. ok last night I rooted my kids tablet with kingroot app and then I removed the unwanted pre-installed apps to give my kid some more internal space for more games/apps. that she would enjoy instead of all the crap already on it. well I must have uninstalled something important because now when it reboots all I get is a blank screen. I think I might of uninstalled nabi mode on accident and now I have no way of getting back into parent mode from the nabi mode screen but im not sure. so anyways I did a hard factory reset and still the same thing happens. like I said I feel really retarded for even trying to attempt this now but now I know not to mess with any of this again I guess. can anyone help me get her nabi back to normal or at least functioning properly? thanks.. and yes this time I will just buy a bigger sd card like I should have in the beginning please don't judge me lol.
[Fuhu Nabi 2] aicjofs:
You will have to reinstall boot, system and addon to get it back would be my guess.

Use this procedure

http://xdaforums.com/showpost.php?p=51037177&postcount=21

but substitute 2311 with 3013 file below(2311 was two downloads, 3013 is just one download to get all the files)

https://drive.google.com/file/d/0B08qqrSbn4djOFQ1a0cwQjVEV2M/view?usp=sharing

skip doing the bootloader stuff I quote below or you will make problems worse

Can only boot to TWRP.

I wanted to debloat my kids nabi2 nick us version and something went wrong and I've lost the backup twrp made and anything I flash or restore with only gives me the nabi boot logo and thats it. It was completely updated to current when I started this journey. Any ideas?
[Fuhu Nabi 2] aicjofs:
This is what I have, untested as I don't have a Nick Nabi. Like the procedure a post above yours, but substitute 2311 with 305N file below(2311 was two downloads, 305N is just one download to get all the files), extract the win files out of the zip and restore. Factory reset my be necessary afterwards too but only do that if it doesn't boot after the restore because you will lose data, saves, etc

3.0.5 Nick Version ROM

EDIT: Oh yeah you were the one that tried converting the Nick to Orig, sorry I just saw your other posts didn't mean to leave you hanging. You may still have your backup that you made. Different versions of TWRP change the serial number. Did you put it on an external SD or on the internal? Use the file manager that is in TWRP advance settings and look in TWRP/BACKUPS and see if there are more then one serial number.

Data2SD Nabi 2 Disney

Edit: I haven't posted really anything on XDA so for some reason its not letting me quote the post correctly. Sorry in advance.

I have a Nabi 2 Disney I bought for my son a few years ago. I just recently came across this post and decided to give it a try. I should first note that I am familiar with how to root and flash roms on phones but very little background in adb shell and the android OS Structure. So I took the easy way and used the New_boot.img from this and its successive posts. Everything worked great. I was able to boot into the Nabi Disney OS, and it showed the Data partition as being on the Memory card. However I had no Wifi. So I read more through these posts. Tried deleting, rebooting and replacing the config file and still no Wifi. I was able to flip the switch but it would not search for or see any Wifi access. So I did some research and was able to find that the Nabi 2 Disney has a different Partition Layout than the Nabi 2 Original. So then I thought maybe it was a kernal issue and decided to extract the boot.img file and manually do it myself by following these posts and other guides to edit a boot.img. I got as far as trying to rebuild the Boot.img file after going through many programs that will make it easy for me in windows since I do not know Linux. Unfortunately when I unpacked the boot.img, the Command String was blank. So when I tried to rebuild the boot.img file, it failed because there was nothing to put in the command string. My limited knowledge of this stuff has caused a few weeks of pulled hair. So I'm asking the Nabi XDA Community please for Help. If you can either provide me with the correct edited boot.img or shed some light on my problem I'd gladly appreciate it Thank You. It's a Rooted Nabi 2 Disney with the latest update and TWRP.
[Fuhu Nabi 2] aicjofs:
Yes it's likely the kernel differences. None of the Nabi's have a kernel command line. It's passed from the bootloader so it will be blank.

On windows I would use this to work with the boot image: http://boot-repacker.blogspot.com/p/blog-page.html

Use the same directions from the post you quoted

except

-Download and install the program I linked above

-Skip step 2

-In step 5. Using the boot recovery packer select the boot image, and select unpack. Hit OK when it's done (Leave the program open!!) Now look in the location on your computer where you put the boot.img. There will be a folder called boot.img-unpacked. Open that folder. Now you will see a folder called boot.img-ramdisk. Open that folder and find the fstab.mt799 and make the edits described. Note: Its good to use a program like Notepad++ where you can use Unix line endings when editing the ramdisk(http://techtips-it.blogspot.com/2011/04/can-i-convert-file-format-in-notepad.html

-In step 6 go back to the boot recovery packer program and click on pack. Now there will be a new file called bootxxxx.img this is your edited boot image. Change that file name to new_boot.img (so it will work in step 8)

Optional step: If it works upload it and share with the community ;)

Nabi 2 Disney Data2SD Success!!!

Thank you for your suggestions. It worked. It definitely was the different kernal format.

Here is the Nabi2Disney version 304 boot image

drive.google.com/file/d/0BzFM8_iFDNt6dFBIVHhoQTJoNXc/view?usp=sharing

Ugh stupid Noob post blocking. I can't attach a file or submit a link. Hopefully you can copy and paste that.

So in my case I do not have a sd card reader on my computer so I formatted the sd card for ext4 through the Tablet using an app called AParted which can Format and re Partion any partition to any format through Android. Once Formatted, I was able to use the NabiLab GUI 2015 to Install stock to the SD card and then I Fastbooted the New_Boot image. Once it Rebooted, it booted right into the stock boot completely fresh from the SD Card With Wifi. Once it finished installing and updating the Nabi Apps, I installed Titanium Backup and copied over the backup files and was able to completely restore all of my sons favorite games and more thanks to the 32GB sd card I installed. I am choosing to ignore the Internal 4GB (2GB usable) original Data partiition instead of reformatting it since it is useless anyway. It'll make things less confusing (Out of sight, Out of Mind). I hope this helps anyone else with similar issues. and Thanks to the Original poster ashahin1 and the added guidance by aicjofs.

Nabi 2 With Android 4.4.2 KitKat & Blue Morpho OS

Last year, Fuhu Inc. realeased the Android 4.4.2/Blue Morpho OS This is what it looks like:

If you had the stock os, you moght have seen this too. Currently, this is the latest stock OS, and it may get a Lollipop update in a few months. I'm asking, will this work on KitKat, or will I have to restore to 4.0/4.2? Thanks for your help. :)

Are you asking will Nabilab work for this? If so, then no it will not work. The closest tool that will work is NabiLab GUI 2015. Installer in my sig.
[Fuhu Nabi 2] Midland Rob:
Hi.

Noob here with a question...

Am I able to reinstall he Nabi 2 OS? (I am such a noob I don't fully understand the acronyms you are all using here).

My son's Nabi 2 is paired with my windows 10 pc via Nabi Sync and I have managed to 'brick' it. If that is the term for it now does not work.

I hard boot it and get ''Unfortunately, Nabi setup has stopped.'', and I can do no more with it.

If someone is able to walk me through in baby steps and plain English, or post a link to said steps, what I can do to rectify this I would be very grateful. As would my 6 year old son...

Thanks in advance.

Rob.

PS, prior to this I believe the OS was 4.4.2 kitkat.
[Fuhu Nabi 2] aicjofs:
If you haven't modded the tablet in any way and were just using it and then the issue came out of no where then its not likely you need to reinstall OS(Operating System or aka ROM). The quickest way would probably be a factory reset but that will cause you to lose everything(picture/game saves/etc) currently on the tablet. If you wanted to try getting your hands dirty you might be a able to install a custom recovery(TWRP) and maybe delete some cache/data from the Nabi setup app and fix it.
[Fuhu Nabi 2] dawn14320:

[Nexus 9 Q&A, Help & Troubleshooting] Asaggynoodle:
Funny you posted this...

I've not had problems with it charging or connecting to a computer.

Although, I've had problems getting the damn thing to charge while I'm using it.

Even with it plugged into a 2.1A charger it usually keeps the same charge or even drops 1-2% while playing a game or whatever.

If I keep it at idle or in sleep it charges no problem. Not sure what the problem Is, I mean if it's inputting 2.1A which is limited by the Kernel to 900mA (Why that is-- is stupid).

I'm assuming that the device uses somewhere at the ~1.2A under full load.
