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!

Would I be able to update TWRP within TWRP using a 2.4.4.0 zip file?

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.

Crossing my fingers... I will try what you mentioned and no, I don't have NVFLASH. Something that I have been meaning to do for a few weeks now too. Thanks for the help I will update when I get a chance to try.

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 am able to adb reboot bootloader, and it brings me to fastboot!
I successfully executed the steps you gave me but I didn't get the android screen with the blue line... it went back to TWRP 2.2.2.1. Can I fastboot the new version of TWRP?

Tried one more time with no success... Please let me know if I have any other options since I can get to fastboot via ADB.
I think the reason I am running into this mess is because I didn't download the JB update from ASUS and move the system.blob file according to Urkel fresh start

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.
Have a look at this thread. http://forum.xda-developers.com/showthread.php?t=2179874

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?

I doubt it will but he can try.
No luck flashing the .img file instead. This is the worst
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.

Hello,
I decided tyo go ahead and try to flash CM10 on my phone and when I did it got stuck at the HTC boot screen upon reboot.
I followed all the detailed instructions and this still happened to me. I figured that I could go ahead and apply the stock rom back just like in other cases of a soft-brick. However, this time upon updating it gave me the "Main version is older! error Press Power to reboot" when installing the stock RUU. Seeing as hansoons tool has a fix for that I apply it and it gives me now "Hboot version is older Press Power to reboot." This is now where I am stuck at. My phone is S-ON and I cannot find a way to turn S-OFF without actually booting into the actual OS. Is there a way and a different route I could take to un-brick my phone? Thanks.

are you using 43xt recovery? if not you need to use it since your s=on
and to get it to boot, use his tool to put that recovery on. and then reflash the cm10 rom. then it should work.
i believe that when you flashed it the kernel didnt boot.

I had this same problem yesterday and corrected it by doing the following you need to put the phone into fastboot mode hold down power + power down once bootloader comes up click power again plug your USB in go into CMD (If On windows) CD to C drive then cd to the folder you put the files in below and run fastboot flash boot boot.img. The boot.img is going to be the boot.img from the rom you are using. This worked for me yesterday. When installing a rom make sure you clear Dalvik Cache,Cache & Wipe Data Factory Reset as well as formating your SD Card. Then toggle USB and copy the ROM over I would use 4EXT it is the best recovery out there.
Code:
https://dl.dropbox.com/u/102426750/XDA%20Dev/HTC%20Amaze.zip
Put these files in a folder in the root of your C drive. Once you cd into that folder with these files run the commands above

Isn't 4EXT like... the *COUGH*BEST RECOVERY FOR HTC DEVICES*COUGH*
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

Hmm that is it weird. It does look like gapps is still installed .As gapps removes gallery2.apk and why it's failing, I don't understand if it's stock how that is happening. Use these updates yet? http://forum.xda-developers.com/wiki/Fuhu_nabi_2
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
-You will need the APX driver as well.
-The nvflash package

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.
I have S-off, Unlocked Bootloader, and my EVO is rooted. I have HBOOT 2.09
I tried to install Vanir so I flashed the Gapps 4.4 in TWRP which seemed to work, then I tried to flash Vanir after and got an error.
Now no matter what I do I boot right into recovery and can't seem to figure my way out. Clearly I'm in over my head so if someone could just help me get back to stock at least I would really appreciate it. Thanks
Did you install the proper twrp for kitkat.. if so just try flashing the Rom first then let it boot up and sit for a minute.. then boot back into recovery and flash gapps this works for me..
Sent from my EVO using Tapatalk
It's 2.6.3 twrp, and whenever I tried to install the ROM it gave me an error message.

Even though you use TWRP 2.6.3.0, it has to be a modded one that allows SELinux support.
Click Me -Flash the Recovery in the OP of this thread
If you have a working fastboot and adb environment on your computer you can flash it by going to to fastboot USB in the bootloader of your phone, and make sure your phone is connected to your PC properly.
Place the .img file in your adb and fastboot folder and then open a command prompt from that location.
then type fastboot flash recovery "recoveryfilename.img" and ofcourse replace recoveryfilename with the actual filename.
after that reboot into recovery and try reflashing Vanir.
This is the method I use to flash recoveries, its fairly simple and fast in my opinion.
Hope this helps.

Ah ok. Glad you got everything sorted out.
Good deal.
Sometimes an RUU is all you have left. A powerful option no doubt.
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:
http://forum.xda-developers.com/showpost.php?p=48987089&postcount=2088
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.
Hello,
I just purchased this phone knowing that it has this problem and I am trying to fix it but I do not know much about the original firmware or anything except of the following:
SKU: 6233A, MFG: 2014/05/30, HW: R1.6
I need to restore the Firmware and preferably be able to use the Dock Station (reason I bought it).
I also like to use it with T-Mobile and do not know if these phones are locket to ATT or not.
I am not a developer but have good technical knowledge.
Any advice will be appreciated.
Thank you
Mike

Hopefully you can enter in to fastboot mode.
Try to reflash this ATT_userdebug rom from TWRP recovery, and then restore this backup.
1. Turn on the fastboot mode(vol up + power), plug in the cable to PC, open CMD, Boot in to twrp(fastboot boot recoveryyouchoose.img) and use "adb push filename.zip /sdcard"
2. install .zip then reboot
3. boot up, then boot back to TWRP recovery, make a backup.
4. boot up, copy the downloaded backup, boot back to recovery
5. restore it.
hope it works

To find out, you have to put your phone into fastboot.
To do that power down your phone, then hold volume up and power button at the same time. There, the asus logo will pop up like normal and hang on that screen to show that you are in fastboot mode.
Open up command prompt and verify your device is connected, by typing in fastboot devices.
If it shows up good then all you have to do is type in fastboot oem device-info.
If it says device unlocked: true that means your BL is unlocked.
If its not, you have to download crowlock from the cm12 thread and flash it.
It works better with cwm but since you are stuck its worth a shot to flash it under old twrp.
Then check the BL status again, if its good great.
You could restore your device from some backups posted or if you could find a boot.img from the stock image, you could use the new version of twrp to flash the boot image under image flashing.
This is the adb/fastboot driver I use http://forum.xda-developers.com/showthread.php?t=2588979
Justatechie you are only one who help. i appreciate it. god bless you!
i've done it. unlocked already. i watched bootloop so i wiped everything. what rom to install?
del
Nice to hear that.
Well it depends if you want to install one or you want to keep it stock.
For keeping it stock unfortunately you must restore from backups posted.
If its custom well Cm is a good way, just the dock does not work, but it will work hopefully soon when the developer receives it soon.

Dont worry about the asus_toon, it will turn back into padfone x when you are finally able to restore to the at&t factory rom
What is very strange,is that you cannot wipe certain things, I guess It may be due to a tampered bootloader. (something must have tripped it up)
My bootloader is unlocked but not tampered.
But the reason why it says ASUS_T00N is because you installed cm or miui and it changed build prop and the partitions. (all of quarx roms are built from the pfs source but work on the pfx too) its not a big deal don't worry.
Have you tried any other recoveries, perhaps the older version of twrp Here
Try booting them through fastboot using the fastboot boot filename.img (of the recovery file that should be located inside a folder containg fastboot/adb files)
See if they can wipe cache data(no media) and system. Remember, booting from fastboot is just temporary
Then try flashing a rom, doesnt matter what it has to be but it should work after its done. Maybe flash without gapps, it could sometimes cause a random problem and besides you can always install it later.
I never had to use fastboot to wipe cache either because well I could do that in recovery, plus its safer
