[Q] Stuck in a boot loop after using ASUS unlock tool - Asus Transformer TF700

Hi guys,
I had a stock tf700, running ICS (4.1.1) and I followed the really good guide by sdbags on how to unlock/root.
I rooted it with no problems, and used the ASUS unlock tool which seemed to work (it says that my device in unlocked), but now I am stuck in a boot loop
It fully boots up and can stay working for about 30 seconds to a minute and then it just reboots.
I can get access to the bootloader but I have no idea what I'm doing. I haven't installed TWRP yet either.
I'm sceptical of just hitting "wipe data" as I hear I could brick it for good.
Any help would be greatly appreciated....I'm really at a loss!!

I've seen this behavior when the kernel was newer than the bootloader and incompatible - but if you haven't installed anything yet this is unlikely to be the reason for your problems. You can try to enable USB debugging, run "adb pull /proc/last_kmsg" and see if that file contains any interesting information about the reboot.
If you want to wipe data, you can choose RCK from the bootloader menu - if it loads the stock recovery (Android mascot with red triangle), you know that the recovery is good and you should be safe to run "wipe data". I have only seen the stock recovery once and that was almost 2 years ago, but if you press the Power button in the recovery, you may even get a menu from which you can wipe directly from the recovery (use power and volume keys to navigate).

Thanks for the advice. I chose RCK from the bootloader menu but it just boots normally....no Android mascot. Am I doing something wrong there?excuse my complete newbness)
Is there a big risk in running "wipe data"? If I haven't installed any custom ROMs or flashed anything yet, is the risk of a brick slightly reduced?

There's not much one can do wrong here - turn on tablet and hold volume-down until the bootloader menu appears, then hit volume-up to confirm "RCK", that should boot the recovery. If it starts the regular OS instead, something is wrong.

I wouldn't risk it if you can't even get to recovery manually ("wipe data" uses the recovery to wipe - if the recovery doesn't work, it's a hard brick).
Try installing TWRP via fastboot.

Thanks for the advice. I took a couple of days break but I'm back trying to fix it.
I tried RCK and it just boots to a dead android man with the triangle error.

Also, I tried flashing TWRP via fastboot but after entering the flash recovery command, I keep getting an error message after entering saying "Too many links". Do you have any idea why that may be? I'm flashing TWRP 2.6.3.2

Asus TF700T Tablet fix
Try this, it worked for me....and the standard disclaimer: I am not responsible if you misunderstand instructions I give here, if my instructions are wrong, if you forget to charge the battery and the tablet dies halfway through a flash or if your house goes up in flames. YOU DO THIS AT YOUR OWN RISK
Ok, so I think that I may have lost power during an upgrade (can’t think of any other reason for it!!) and ended up soft bricking my Asus TF700T tablet and recovery attempts would just lead to the dead Android with a red triangle with an exclamation point in the middle. My warranty having expired with Asus and any attempt for their assistance proved fruitless.
Well I researched and tried absolutely everything out there – (Hard Reset, installing TWRP, used a tool called Motochopper and flashing a custom ROM, downloaded and renaming .zip files, putting it onto a Micro SDcard is formatted Fat32, Scotts Tf700t Recovery etc.etc. etc.)
I even took it to the local shops and paid to have one of the Mobile Technician pop-up stores take a look at it, then a friendly techno geek………all with the same suggestions most likely a motherboard/hard drive problem.
My Asus TF700T tablet eventually ended up with just the plain white ASUS logo in the middle of the screen, some small print in the top left corner followed by the dreaded words “Unrecoverable Bootloader Error (0x00000000)”.
During all of my research I was led to believe that if you can still get to the recovery screen, where you see the 4 icons, all is not lost so I persisted.
Here is the instructions that I followed that restored my TF700T:
Download and install ADB, Fastboot and the required drivers - Download and run this cool little tool which has it all packed into one: [TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.1 - xda-developers (don't forget to hit the Thanks button)
NOTE: at the moment Fastboot seems to have issues with Windows 8
This awesome tool installs the ADB and Fastboot.exe to a folder on your C:\ drive (look for a file titled “adb”) as well as the corresponding drivers. This takes about 15 seconds to install following the prompts.
I installed the device drivers - if you have already tried to connect the tablet to your PC and it's recognised as a portable device you should be ok. If not, download the Asus Sync Utility from their support/downloads site and install it.
Download the latest firmware from Asus (Always make sure that you download the correct SKU version -WW, US etc.) and extract the zip twice so you access the blob file (a blob is a collection of binary data stored as a single entity) – copy and paste this blob file into the previously mentioned “adb” folder on your C:\ drive.
Reset the device with a paperclip/needle (about 2 cm down of the SDcard slot)
Power down the tablet and disconnect it from the keyboard dock.
Connect it to your computer via the original USB cable.
Push and hold the Volume Down key (left side of the rocker) and the Power key until you feel the tablet vibrate twice. Let go when you see the tiny script. Read it and it tells you that your tablet is now in Fastboot mode and you will see three or 4 icons (depending on the bootloader version). Select the USB icon to get into the Fastboot mode.
Your PC should acknowledge that a USB device has been connected (an audible indication) Don’t panic if the device does not appear under “My Computer” (as mine did not either – Fastboot will still communicate with it), you can go into Control Panel/Hardware and Sound/ Device Manager and you may see “Fastboot” icon, expand this and the device will be represented again by the “Fastboot” icon. Right click, select “Properties”, Driver tab and then select “Update Driver” and allow it to search automatically and update from the internet. This should then update and change to Asus icons. You now can be certain that you have the current device drivers.
In Windows Explorer navigate to the folder that contains your adb.exe and fastboot.exe
Win 7 press Shift + right click and select "Open command window here".
In the resulting command prompt screen type the following codes (those in bold):
C:\adb\ (or whatever the path to your fastboot folder is..)
fastboot devices (If that command returns a string of numbers and letters, you are good as gold. If it returns: "No devices found", fastboot is not working - yet - and you have to troubleshoot)
Followed by each in turn of the below, selecting Yes as required and allowing each to complete the process:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
The resulting screen should look something like this below – NOTE, I did make a couple of typos while I was attempting this which returned some multiple choice garble if this happens recheck you input instructions:
E:\asus>fastboot erase system

finished. total time: 0.020s
E:\asus>
I disconnected and rebooted My Asus TF700T and I now have a fully functioning Tablet with a stock ROM.
It has been reported that after completing this you may have some issues getting back get into recovery, hitting RCK and getting the dreaded dead Android (with a red triangle with an exclamation point in the middle). I have not attempted this but have been led to believe that flashing TWRP 2.7.0.1 via Fastboot works.
All acknowledgement and appreciation for this method should go to Buster99, a Senior Member of XDA Developers

Unrecoverable bootloader error but not Bricked!

So I unlocked my tf300t and flashed cwm to recovery.
Everything seemed to go fine.
When I would go into cwm it was not able to mount or access any other part of my tab. I figured ok erase/format the recovery partition and try TWRP. So I booted to the bootloader, using fastboot I erased recovery but now whenever I go to flash a new recovery my bootloader either freezes or I get an Unrecoverable bootloader error 0x00000000 (not sure if thats the right amount of zeros but there are no other digits in the error code.) I can access fastboot and adb but it doesn't seem like I can flash using fastboot and I just don't feel comfortable trying with adb. Also I can access fastboot only from the bootloader screen and adb only after I boot into my current rom (stock 4.2.1)
I guess my questions are this:
How can I format my recovery or flash a new recovery?
Were the mount issues I originally encountered going to be solved with a new recovery?
Please help!
Have you tried installing stock rom (from Asus support page) using Fastboot? It should also put stock recovery in your tablet.
Not sure if it is going to work, but it's worth trying though.
1st this is not for the dev section. You should ask questions in the Q&A section.
Go to Asus and dl the latest Stock. Unzipp it 2 times. You should have a blob file now in the extracted folder. put this blob in your fastboot folder.
Open cmd and type:
fastboot -i 0x0B05 flash staging blob
let it run. It seems that nothing is happening for about 5 Minutes. The whole thing can take up to 20 Minutes, so just stay calm and wait till its finished.
Now you should be back to full Stock with Stock recovery.

I had this problem too. But on 4.2.1 you can push file blob, and then it's can't run because stock recovery dead.
Were you able to fix the stock recovery issue?

No, I was not. I also have the unrecoverable bootloader error but I have a working device. I downloaded the latest firmware, followed the steps through fastboot and the same thing keeps happening where as soon as you try to enter a command through fastboot the green box stops flashing over rck and even though the cmd prompt window tells you something is going on nothing happens on the tablet end. It freezes. hard reboot and you end up back with a normal working device, no changes and a corrupt bootloader.

I was having this problem earlier - a new bootloader came out when they went to 4.2, but most of the instructions online don't reflect this. You need an updated recovery image, which usually has the name recovery-jb.img instead of recovery.img. When you're searching make sure the instructions mention 4.2 and jelly bean.
However, I've only managed to get one step further - have now get into clockworkmod recovery, but as with the OP I then couldn't mount anything inside CWM. I tried another instruction set which involved unzipping the ROM and using adb to push over the .blob. This hasn't worked and I have now got a pretty much bricked device - it either bootloops on the asus splash screen, or loads into CWM.
I've found that even when youre in CWM you can type "adb reboot-bootloader" into the terminal, which forces the RCK/android/wipe data page and fastbook to appear. I've also tried to download the latest stock firmware from ASUS, unzipped it to get the stock .blob out and into my fastboot directory, then run "fastboot -i 0x0B05 flash staging blob" in the terminal, as per mikaole's suggestion. This takes a while to push over the 80mb .blob, but after it says it's staged it says "done" then nothing happens and it's still bricked. hmm.
No one's figured this out? I tried flashing the blob file and my system won't boot at all
My solution
I have the same on my TF300t and A700 - but it seems i just managed to get my TF300t back
i tried all fastboot (reflashing recovery, boot, system etc) no dice - especially since writing system was done after 3 secs all the time.
Here how i restored my TF300T JB
download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
(the folowing i did at least 10 times already but didn't erase misc)
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob) ((also this was the first time i saw the loading bar while flashing)*
fastboot -i 0x0B05 reboot
* it also took a lot longer as it should:

Did your tablet seem to freeze after flashing via fastboot? When I push blob, the console shows that it wrote, but then fastboot on the tablet freezes & I have to manually reboot, putting me right back to the drawing board.

Until now my device freezes. Fastboot seem to work but nothing happens. :banghead:

nope. do you use the original cable on usb 2.0 and connected to your pc not a usb hub? should work. if not try a diffrent pc - sometimes usb chipsets make problems.

[Q] A700 unable to boot into recovery after flashing cm10.1

Hi there,
thanks to this forum I was able to flash several HTC phones sucessfully, but today I got perfectly stranded.
The original android version (jelly bean) of the Acer A700 was 4.1.1.
The plan was to get root access and put on CyanogenMod cm-10.1.0-RC5-a700.zip
Here is what I did:
- unlock the booloader (fastboot oem unlock)
- getting root access using easyroot.bat
I checked root access via "rootchecker" and everything appeared to be fine.
- Installing ClockWorkMod Recovery
- Under "recovery" I selected the A700 and also flashed the touch version of CWM
I opened up CWM and selected "reboot into recovery"
The A700 did was it was told and I got the usual CWM menue and could see the
desired cm-10.1.0-RC5 on my SD card
So far I was impressed how simple everything went and carried on flashing the CM10.1.
Before I did so I made a backup of the actual ROM on my SD card, then I selected
"wipe cache" an started the flashing process from the SD card.
Everything went fine and after a short time the rotating CyanogenMod Logo appeared.
However, the logo keeps on spinning an nothing else happens any more (20+ minutes)
I powered off the device and tried it again with the same result.
I also tried to press [power] + [vol -] to boot into recovery.
Letting go the [power] button and keeping the [vol-] button pressed after the device
vibrates for the first time brings up only "bootloader version JB365b3d3 (unlock mode)"
but the second line "loading recovery kernel image" does not appear anymore
In other words pressing the keys will show no difference to a normal start procedure.
When I connect the A400 with my PC and type in "adb devices" I get its number but the comment "offline"
In short, I have no idea what I could have done wrong nor how to access the device again
Is there someone out who can help me? - Thanks a lot in advance!
Comming from stock ROM, You must do Factory Reset / Wipe ALL to boot properly CM 10.1
About ADB, you must upgrade your Android SDK/ADB tools to the latest version, ADB changed a little with Android 4.2.2
With adb working, you can launch
adb reboot recovery
It should work, then make factory reset, and try to boot
Thanks a lot for the very fats response ... to be honest I thought, questions like mine are unlikely to be answered (oh no, not another dung-head who bricked his device)
However, I downloaded the latest adb version (dated 2013-05-22) and tried it again, but without success.
I can apply [pwr] + [vol-] ... [lock] to bring it into fastboot download mode.
At least the A700 shows the following lines:
Bootloader: Version JB-652b3d3 (unlock mode)
Bootloader: Version JB-652b3d3 (unlock mode) Starting Fastboot USB download protocol
Having achies this I tried to re-flash the initilally installed but now missing CWM

Having done this I expected the CWM to be again on the A700, but when I start with [pwr] + [vol-] the A700 still does not boot into recovery.
Again I get this:
Bootloader: Version JB-652b3d3 (unlock mode)
followed by the nevern ending spinning CM10.1 logo ...
Without the adb running I'm pretty hopeless ... does a factory reset change anything at this stage?
You can try
fastboot boot root/recovery-clockwork-touch-6.0.2.3-a700.img
to go in recovery
and then in CWM
wipe all/factory reset
flash CM 10.1 again
flash gapps
reboot
We are ariborne, Sir!
Ereasing all partitions and flashing CWM again did the trick

[Q] Cannot Reboot Recovery

I am running CM10.1, and wanted to upgrade to the new nightlies, Upon trying to get into recovery, I cannot use goo manager to installed recovery nor reboot to recovery. I did then try to push TWRP to my device using fastboot, that did not seem to work as any time i rebooted to recovery it would do a normal reboot. I can access fastboot, however when I volume up on "RCK" the following error comes up
Key driver not found..Booting OS
Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.14.4-20130329" A03
Starting Fastboot USB Download protocol
Booting Recovery kernel image
Booting Failed
Unrecoverable bootloader error (0x00000000).
I do not know if I have everything loaded into my PC correct, drivers, etc. Anyone who can help would be greatly appreciated.
As i am now I can run CM 10.1 just fine, booting and everything, I just cannot get into recovery to upgrade or change roms.

I don't know if this method will work on CM. You can give it a shot and report back.
1. Download the Asus firmware from Asus website and extract it once because there is anotherr zip in it.
2. Copy the second zip file to your root directory on your internal sd and reboot
3. If it works, you should see the notification on the lower right corner and click on it. You just follow the instruction to put your device back to the factory bootloader.
Before you use this method, you need to move all your stuff to your computer as a back up because it will wipe everything that you have on your device..
There is another method that you could try if it does not work.. Good luck..:fingers-crossed:
I tried to download the US Firmware from the ASUS site, put it on the root of the internal, then rebooted. Did not see any notification
What is this other method you speak of....
This isn't a huge deal, if I'm stuck on a RC of CM 10.1 I can deal with it. I just like to be up to date and like to reconfigure my tablets and phones from time to time.
On a side note, isn't rom/recovery etc tasks with this tablet very difficult when compared to other tablets/phones?

Did you unzip it once? You need to have a different firmware version than the one on your system... I will find the other method and link for you..
Thanks Man. I appreciate the help!

I am still looking for the link. I forgot what it is called... I will post the link here when I find it..
LetMeKnow, Thanks for the update.
Myp hone is a Droid Razr HD, and I know with that phone its possible through the bootloader to flash stock firmwear, is this possible at all with the Transformer tf700t? It would be great to have a simple tool to aid us in getting back to stock to start from square one!

By reading your post again, let me summarize it here. You know how to use fastboot, can't boot to your custom recovery (TWRP), want to flash stock recovery to fix your problem, and have try a few methods to put the stock back but it did not work. You still can get to your bootloader menu. Can you try to use this command to see if you can access to your custom recovery: fastboot boot-recovery
Good luck and get back to you on the link...
this is what came up in command prompt....

I then did try below. but when I went to reboot, it just stayed in fastboot, so that leads me to believe there is some error there, either my bootloader is screwy or something related. I appreciate your help. At this point if anything can get me back to stock as bought, I dont care if its older versions of the firmware/bootloader/stock recovery, I'll take it from there.

I have not seen that before, so I don't know what to say...
When I did fastboot TWRP recovery, I used blob file instead of img file. Do you want to download the blob file and try again?
Edit: What version of TWRP did you fastboot? V2.6.3.0 is larger than our partition on the tf700. Therefore, you can not use it..
The .IMG was cwm recovery. I tried that after trying twrp most recent version. 2.6.3.1 I think.
Sent from my XT926 using xda app-developers app
On a side note, when i fastboot the TWRP file to my device, the green blinking box stopped around "RCK" after that when i type in fastboot reboot to reboot the system, nothing happens. any thoughts?
At this point in time, if there is a way to force stock recovery through fastboot or the stock firmware as well, i'd like to give that a try.

If fastboot doesn't work for you but you have a rooted Android, you can try installing a recovery using the dd method:
Code:
cd wherever/you/downloaded/twrp
su
dd if=openrecovery-twrp-2.6.3.1-tf700t.blob of=/dev/block/mmcblk0p4
then reboot - the bootloader should flash your new recovery with a blue progress bar and reboot again. On the second reboot, hold down volume-down to get to the bootloader menu and try entering RCK again.

You mean the expected output? Something similar to:
Code:
15836+1 records in
15836+1 records out
8108136 bytes (8.1 MB) copied, 0.152395 s, 53.2 MB/s
(the above is from my PC - the TF700 is slower)
Or do you mean where you enter those commands? Either via your PC in an adb shell (in this case you must first transfer the file to the TF700 with adb push or other means), or directly on your tablet with a terminal app under Android (I recommend the one from jackpal, search the Play Store)
I was able to get the same output, however when I rebooted after running the last dd code, it did not do anything, just rebooted as normal.

[Q] HELP! Bricked ASUS TF300T

I have an Asus TF300T paperweight!
I started out to root my tablet and load CWM. I unlocked it, install TWRP v2.2.2.2 as I read in a blog with instructions on how to root this tablet. I loaded a CWM ROM, can't remember not which. It didn't load correctly, and kept rebooting. I got into the screen that gives the following four options:
1. RCK
2. Android icon
3. USB icon
4. Wipe data icon
Of course, thinking I would start over and try again, selected Wipe Data. Stupid, I know.
Now, my tablet only boots into TWRP. It won't mount anything; of course, since I Wiped Data, there is nothing to mount. I have tried and searched, to no avail. I can see the tablet in Device Manager, and managed to load the Naked Universal Drivers. Now it shows up in Device Manager as Asus Eee Pad Slider ADB Interface. I can issue the command - adb reboot - and it will reboot, but I can't get it to do anything else meaningful with my meager experience.
Any help would be greatly appreciated. I would like to get this working and give it to my son, as I have already purchased a replacement for myself.
Thank you.

Stop.
Find buster's post and thank him.
And make sure you keep twrp up to date. You have an extremely old versioin which is why you bricked.
I have the same on my TF300t and A700 - but it seems i just managed to get my TF300t back
i tried all fastboot (reflashing recovery, boot, system etc) no dice - especially since writing system was done after 3 secs all the time.
Here how i restored my TF300T JB
download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
(the folowing i did at least 10 times already but didn't erase misc)
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob) ((also this was the first time i saw the loading bar while flashing)*
fastboot -i 0x0B05 reboot
* it also took a lot longer as it should:

hope i could help you out!

[Q] Stuck in TWRP (Bricked?)

Hi Guys,
Yesterday I installed the new TWRP 2.7.1.0. and that is when the problems started. Everytime when i loaded TWRP my screen got messed up and i got a split screen (At that time my ROM worked). So I tried to get back to a older TWRP, after a couple of tries i finally installed 2.4.4.0. But then I couldn't acces my internal memory nor my sdcard through TWRP(The ROM still worked fine). So i tried CWM, other TWRP's, still the same issue. To keep the story short, I eventually pressed on the WIPE button in Recovery ... And now I am stuck in TWRP. I can't load any zip files.. Is there any hope?
Tab: TF300T
A small update. After some trial and error i got my rom running again and i can also get in to recovery (Power button + volume down). Now I have erased the old TWRP with "fastboot erase recovery". But now I can't install a new recovery? I tried flashing a recovery and I am getting the messages "sending recovery ok", "writin recovery ok". But i don't see the loading bar on the tab...
I feel lonely here hehe.:laugh:
I resolved the issue and got my tablet running again, with the following steps:
Download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
http://support.asus.com/download.aspx?SLanguage=en&m=ASUS+Transformer+Pad+TF300T&os=8
Install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
If the PC doesn't recognize your tab, then try installing the universal naked drivers:
