Hi, I did the update here - http://forum.xda-developers.com/showpost.php?p=50341726&postcount=85
And removed twrp. Obviously with my lack of knowledge I
made a mistake. Now I have stock recovery and the nabi freezes on the boot logo.
Any chance someone could help with getting it booting again or getting twrp back on.

If Jellybean is installed, then I think this is what you need to install TWRP for JB onto the Nabi:

Once TWRP is on, your options for recovery are much wider.

Did you do everything else in thread or just that post? i.e. Did you update the bootloader too? http://forum.xda-developers.com/showpost.php?p=50356162&postcount=91
You will need TWRP one way or another. Use the ICS version if you didn't update the bootloader, and JB if you did.
Thanks for the help guys. I didn't realises until after that I needed to update the bootloader too, I'm guessing that's where my troubles start.
Just going to have a look at your links now, I know I could get twrp back on when it doest boot.
Thanks again.
Tried nabilab for ics and jb and both are no longer detecting my nabi.
When the nabi tries to boot the circle around the logo isnt even moving.
Still stuck with the Nabi, if anyone could help I'd really appreciate it. All I can do with it at the moment is boot to stock recovery.

So you installed the 2.2 ROM, but didn't update the bootloader. You have the stock recovery on it right now.
Can you get TWRP back on it?
Can you get into fastboot mode by pressing power and vol down?

Edited -
Yes put 2.2 on it but didn't update the boot loader. Tried to get twrp back on using nabilab buts the tablets no longer being detected .
Yes, I only have stock recovery. When I select fastboot protocol, I then get bootloader, continue, reboot-bootloader, reboot and power off.

OK now you need to put TWRP back on it with fastboot when it's in that state.
Look in the TWRP thread, I'm mobile right now, but basically you need to open a command prompt where fastboot is located and then
fastboot flash recovery recovery.img
Thanks so much for getting me out of this mess. Twrp is back on so I should be ok now with a bit of trial and error.

I rooted and had a custom firmware then I flashed stock firmware which I think was a mistake. Now I can't boot into android or recovery only fast boot. When I try to reboot into recovery it show a picture of an android with his stomach open and a red triangle with a "!" in it. I thought that the recovery image might be corrupt or something. Does anyone know how I might install a recovery image or how i might fix this through adb since that's all I'v got. I have the jellybean bootloader.

Hi All,
Long time lurker and I appreciate all the work everyone does here. It makes owning an android device a great amount of fun...but as you can see by the title of the thread, a great amount of stress as well :laugh:
My device is unlocked and I've used CWM and recenlty noticed that along one of my flashes TWRP 2.4 installed over CWM. All is well because I was meaning to switch over and try this recovery out. Smooth, fast, I like. But I recently installed CM 10.1 using the october version with the JB bootloader because I did not have it. Everything was nice, but I wanted to update CM 10.1 to a more recent UNOFFICIAL build so I flased the 3/20 version on my device. Everything was smooth but the WiFi dropped all the time so I decided to wait out a more stable "official" version of CM 10.1. Take note that I have(had) TWRP 2.4. Now I wanted to stick with JB 4.2.X so I decided to flash Energy's 3/21 build but this hung up on the ASUS screen... So I decided to reflash the rom but first installing the JB bootloader and partitions zip. Still no luck and while exiting TWRP, I noticed that it stated that my device isn't rooted and would I like to root? So I swiped and did it but it seems that the JB bootloader and partitions zip file erased everything on my device, Roms, GAPPS, SU, backups...gone.
The next thing I did was execute Urkels fresh root and fresh start and that seemed to go through all the steps with no issue. When I went back into recovery I noticed that I now have TWRP 2.2.2.1 with a JB bootloader... so what ever I did downgraded TWRP? Ok... Now I wanted to play it safe and stick to the October version of CM 10.1 with the JB bootloader but while flashing the rom (ext SDCARD) i receive an error. I decided to re-execute Urkels fresh root and fresh start and now all my device does is boot into TWRP 2.2.2.1. I can't use fastboot even with holding the power button and vol down.
At this point I feel lost and defeated, I can't use external SD anymore and I can only mount the system. So I decided to see if ADB works. ADB works great in recovery and am able to send files to the device. I sent a ROM to see if I can install but it fails because it can't mount the cache and this is where I am now. Lost... confused and desperate for help :crying: I'll make sure XDA gets a nice donation if anyone can help me out!
What works -
boot to TWRP 2.2.2.1 (thats all)
ADB in recovery
What doesn't-
No rom installed
No backup
No fastboot
My troubleshooting
Again ANY help is appreciated!
Mike

This is happening because you are now on 4.2.1 bootloader with an old TWRP which is not compatible with the new bootloader.
When you say you cannot access fast boot do you mean the usb icon is missing? If you do that is part of the new bootloader. As soon as you get to where the icons are you are automatically in fast boot unless you select one of the icons.
I'm out at the moment but if you reply letting me know that you can get to the icons I will post a file when I get back and some instructions to downgrade you to old bootloader and compatible TWRP.

I figured my TWRP version might have been the culprit...
When I restart and hold the vol down button it normally would activate fastboot, now it goes directly to TWRP, no icons whatso ever. Before I would get the recovery icon, a usb (I think) and an option to wipe data. I can't get to that screen anymore. Is there a command in adb that will allow me to restart to fastboot from recovery? I myself am at work too so I will test anything I can in 3 - 4 hours. Thanks for taking the time to respond! :good:
So basically I won't be able to put TWRP 2.4.4.0 within my current version of TWRP?

The version of TWRP you have will not mount the partitions you need to flash anything. You either need to downgrade the bootloader so that version of TWRP will work or get the version of TWRP back on there that was edited to work with the new 4.2.1 bootloader.
When you installed that partition.zip from energy rom it installed the new bootloader and the compatible twrp the same time. To go back he also has a zip that will restore old bootloader and old twrp. This is what you should have done.
What I am worried about now is the fact that you cannot even get to fastboot from the buttons.
Try adb reboot bootloader.
If that lets you in then download this .. http://flumpster.lolcakes.com/android/blob and place it in your fastboot directory.
Now type.
fastboot -i 0x0B05 flash staging blob
wait for it to fully flash and then type
fastboot -i 0x0B05 reboot
Give it about 20 seconds, if it doesn't restart then you will have to hold the power button down for 10 seconds to force a restart.
When it restarts it should now start to fill the blue line on the Asus screen which will flash the old bootloader and compatible TWRP. If it does this then great, just wait until it has finished and it should put you back into twrp where you will be able to install a rom off your external SD.
If it does not do the blue line then we have bigger probs and I hope you have nvflash backup files.

You cannot do the nvflash process now. You could only do it while on ICS and there is no way back to ICS without having nvflash backups.

I was worried about this. I have seen loads of people with the same problem you have over on the tf300 forums.
They can access fastboot thru adb reboot fastboot and it appears to send the file over ok but then it doesn't work.
When you mentioned you couldn't get to fastboot by holding button combo it looked like the same prob as them.

So I probably need to send it to ASUS or wait for a solution? That is for the TF300 would I be able to use any steps for that device with mine?
Also,
I purchased this in January 2012 from best buy, any possibility I can go through them to have this issue fixed?

Flumpster thanks a bunch for all of your help. I ended up sending in the tablet, as expected they had to replace the motherboard.:
They quoted me this origionally:
Parts: $165
Labor: $65
Shipping $10
TOTAL $240!!!
I called and complained until my eyes popped out of my head and they ended up replacing the motherboad and shipped it back to me for $150. Now I think I'm going to sell this thing with the dock and buy a Nexus 10. Again, thanks for your help.
Another note... It will probably be a pain to unlock and root this thing again after the RMA im assuming. No more ASUS.
I wanted to upgrade my Nabi with the latest OTA. I had TWRP 2.2.2.1. I used it to revert to an old backup. After the restore, I tried to apply the OTA updates. After it rebooted and started the install I got an "!" Android logo.
I power cycled and I was able to boot back in. I noticed I still had the Play Store app (which will not work, error about connecting to services) and suspect the "stockunrooted" restore I used may not have been completely "stock". I did lose root and TWRP though.
I tried to reinstall TWRP again, but it appears that Fastboot no longer works since the restore. The tablet just hangs on the Nabi logo indefinitely. When I press Vol - & + with PWR, and select Recovery Mode, I just get another "!" Android logo (is this stock recovery?).
ADB works, it sees the tablet and I'm able to push, access shell etc.
I used motochopper to root the Nabi again. I tried installing flash_image to manually flash a new TWRP recovery.img, but running the command I get an error about "error scanning partitions".
I'm not sure what else I can do to get Fastboot working or a recovery system installed again. OTA upgrade will not apply, and I'm stuck on 1.9.37 at this point.
Does anyone have a suggestion how I can get Fastboot fixed and the Nabi back to "normal" / upgradeable.
Thanks for your help

That is usually a sign that various Google services are removed from the system partition. So in that case it is returned to stock, but there is still information of the Play install on the data partition.

Usually when it hangs at the Nabi logo it means you don't have the USB cable plugged in or that the fastboot driver is not installed.(Check device manager and see if fastboot driver is installed/no exclimation point). If that's not the issue then it's the bootloader which I have only seen one person have that issue. Depending on which OTA's you have ran there was an update to a Jellybean bootloader so it's possible. That can be fixed with nvflash or placing the bootloader blob in the staging partition.
Also you can always get recovery back without fastboot in Android by dd'ing the recovery over.
For example if the recovery image is on the internal SD
dd if=/data/media/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS

OTA is trying to install 2.1.27
You were correct about the fastboot driver issue. I was using Windows 8.1 and it it wasn't working properly. I switched to Ubuntu and now have no problems.
I was able to flash TWRP 2.3.3 and tried another restore to stock. Did OTA again, but still get the "!" Android shortly after it reboots and starts installing. I can't seem to get rid of gapps either. Play Store is still installed. I've tried wiping /data/media, cache's etc and it still remains.
I'm not sure why the OTA upgrade keeps failing. Do you think it's due to the gapps still being on the device?
Any other ideas on how I can get the OTAs to work?
Update:
I booted up stock recovery and tried the update from cache

This thread died out....I hate to bump it back to the top...But I have a NABI2-NV7A that I rooted along time ago....and i booted it up and was gonna do some upgrades and everything went kaboom!!
I have TWRP 2.2.2.1 installed.
I can get into TWRP but not fast-boot mode
I'm on a laptop with windows 10 installed...I don't think it's driver related....as i can send commands via adb while TWRP is up....and the NABI responds to those commands
But i never get past the logo screen....and I'm not sure what to to do with NVflash.
I'm experienced...but rooted this thing and installed GAPPS like 2 years ago and the kids dug this thing up and the play store wouldn't work any longer....i read about the OTA....so i was trying to go back to stock and get those OTA's.
Any suggestions or advice?? Anyone...hello....bueller....bueller

Have you tried using "adb reboot-bootloader"
There are some things to try before breaking out nvflash. The easiest would be to flash the boot loader and a new TWRP in one recovery session.
Boot twrp2.2.21, Install KK boot loader zip and then install TWRP KK287 zip
Then restore the 3.0.13 ROM
Files and directions here

I did try ADB REBOOT-BOOTLOADER all that happens is the NABI2 restarts and sits at the logo screen.
I'm able to push via ADB, so I will download the suggested files and take your advice. I'll report back. And, thanks for the reply.
Update...
I was able to push all of the needed files and I verified I pushed them completely by using "adb push -p xxxxxx /sdcard"
I then rebooted back into TWRP
I flashed KK3013bootloader.zip, then flashed twrp-recovery-NV7AUS-287.zip
Rebooted and I can't get back into TWRP. And, now I can't establish a connection for adb commands.
Any advice? tips...pointers? Could this truly be my first bricked device??

Nah Nabi2 is practically impossible to brick.
So do you get the command list in the top left when you press the vol and power buttons? i.e the selection continue, fastboot, recovery kernel, forced recovery? or when you select recovery kernel it just doesn't boot TWRP?
I wont type a lot of stuff until I get you answer but if we need to go the nvflash route this is some good reading. You will need to get in to APX mode, install the driver and issue some commands.

Might be some work, but we should be able to get the device back, I'll let you know which is the best way after I see your reply.
Yup, no boot options. And, I can't get back into TWRP. I hold power button to shut it down. Then vol+ power and typically I'd get the boot options, but nothing, just the logo. Then hold power button to shut down. Continue...repeat...
I appreciate you sticking in for the long haul on this.

Damn. It IS going to be a long haul, but you will know the tablet well when its done. I don't have the tablet to test anymore, so I have to work from memory(and that's been a long time)
Well the bad news is this is going to require opening the tablet. See this post http://forum.xda-developers.com/showpost.php?p=46694284&postcount=1701
You are going to have to short those pins to get it in to APX mode and use nvflash

Damn. It IS going to be a long haul, but you will know the tablet well when its done. I don't have the tablet to test anymore, so I have to work from memory(and that's been a long time)
Well the bad news is this is going to require opening the tablet. See this post http://forum.xda-developers.com/showpost.php?p=46694284&postcount=1701
You are going to have to short those pins to get it in to APX mode and use nvflash

Get the nvflash package from the Nabi General Info thread I linked above
Unzip in to a directory of your choosing and open a command prompt in that folder
The Nabi will be broken open and connected by USB to computer
So once you get those pins shorted and press the power button the screen should come on and be completely black(you can tell the backlight is on though)
Check in device manager for a new device(it will be auto detected or you will have to manually install APX driver)
Once the driver is installed you can issue nvflash commands
nvflash --bl bootloader.bin --download 4 bootloader.bin
Before pressing enter for the below command get ready to press and hold the vol+ key.
nvflash --resume --go
Right on. I'll dig into this in the morning

@aicjofs, I still haven't begun breaking the Nabi down. I'm working from home today and should be able to squeeze the disassemble in sometime today.
I scanned through the comments you've left since finding out I wasn't able to get to the boot menu...I'll post back once I get it torn apart.
Hi All,
I have a HTC ONE X+ on O2 UK, it has HBOOT 1.72, S-ON, Radio-3.1204.171.33
I tried being clever and Rooted the phone following hasoon2000 instructions. It was so simple and worked so well i got cocky.
Successfully rooted and installed TWRP 2.6 recovery, used the phone for the whole of 5 minutes before deciding if that was so easy i may as well try flashing a ROM....
I tried CM11 snapshot 15/09/2014, it failed so i restored my back up and all was fine. On the CM wiki i read this bit ..
This device, if unlocked with HTCDev Unlock, must have its kernel flashed via fastboot. Extract boot.img from the CyanogenMod .zip package and flash it from the bootloader with: fastboot flash boot boot.img

So i did that, and now i am stuck in boot loop of the HTC quietly Brilliant screen.
I can get into recovery restore my backup but i am still stuck in a boot loop. I assume i need a boot.img with certain information to allow it to go any further. I tried the
RUU RUU_ENRC2B_U_JB_45_O2_UK_1.14.206.13_Radio_3.1204.167.31_release_289474_signed

but assume the problem is my HBOOT and Radio are more up to date. (Shows error on screen saying incompatible)
My ideal would be to have a working CM11 Snapshot or CM10.2 on the device, i would settle for stock and back to 4.2.2 and working.
Any help would be great.
Cheers

it tells you to use clockworkmod recovery and not twrp. atm you can't use twrp for kitkat based roms
hold power button until phone turns off. then turn on holding VOL-DOWN to enter bootloader.
now you can flash cwm recovery and boot.img extracted rom.zip
You can only flash a new kernel by booting in the bootloader.... Therefore, whenever you switch rom you'll have to flash kernel compatible to that particular rom.
So, enter bootloader, connect your phone and use command "fastboot flash boot <kernel path>"

Seemingly it was as simple as not being able to use twrp with the latest CM11. Thanks so much, happily on 4.4.4 now.
The thread was from 2012 and the twrp site seemed to indicate otherwise, but soon as i switched recovery it was sorted.
Cheers!

Fixing TWRP is on my list of things to do...by the looks of it I need to get to it sooner rather than later
Hi, I oem unlocked my Nexus 9, installed TWRP and SuperSU, but I think I missed a step before I can go to custom ROMs and all. I've looked for instructions but I'm just getting confused. I firstly cannot reboot into TWRP unless I fastboot boot recovery from my PC every time. If I don't do that, it just boots into the Flounder PVT Ship white screen with Fastboot USB in red and below that HBOOT, REBOOT, REBOOT FASTBOOT, and POWER DOWN.
What step am I missing in this process? Do I need some sort of custom image or what am I doing wrong?
Thanks,
Chris
Hello,
It can get a bit confusing sometimes and people generally expect you to just know lol.
You've not missed a step. Getting into recovery is irritating lol. For as long as I've had it if booted into recovery from the power menu lol xD.
Reboot the Google Nexus 9 by holding the Power and the Volume Down buttons at the same time and wait until the tablet display shows a Google splash screen before releasing the buttons.
If you get a android with an exclamation mark then you've made a boo boo. Dw, even us pros muck up ;]
Go back to your fastboot. Flash twrp like you do. But this time once you've flashed it type
Code:
fastboot boot recovery twrp.img
That should boot your device into recovery after flashing it.
There it should be stuck on there nicely of it takes a while Dw. That's just the fun of owning a N9 lol. That should Do it .
Happy Flashing.
Give us a Thanka if I helped

If you installed TWRP using
Code:
fastboot flash recovery twrp.img
The only ways I know to get into recovery are to reboot to recovery from the Power menu of your ROM
OR
Boot to fastboot, select HBOOT, then select Recovery. If TWRP is installed as your recovery this will boot TWRP. If it goes to the dead droid screen then you need to install TWRP properly, using the fastboot flash command above.
I can't get my nexus 9 to run twrp as well.
I go to fastboo, select Hboot, then I get the android with exclamation, volume up and power brings up the original android recovery menu, not twrp. I've unlocked the bootloader, wiped everything and tried again, no luck. Always the same result

Are you using the newest TWRP? 3.1.0.0? It's not working for me either, can't boot to recovery. Use 3.0.2.2 or whatever the last version was
I used the 3.1.0.0
the trick was, after installing it, reboot straight back into recovery, so it doesn't get overwritten
