Hi all,
I've flashed CWM 6.0.2.3 instead of TWRP 2.5 to recovery partition after having unlocked the ASUS JB 4.2 bootloader using ASUS unlock tool V8. After that ASUS JB 4.2 was running well but not with root access AND i did the big mistake to use the wipe function in the bootloader ... since then i'm stuck in a boot loop with access only to CWM but i can't mount anything (internal or external sdcard) ! The good news is that i have still adb access under recovery => i run 'sudo adb reboot-bootloader' to access the bootloader menu which also provides me fastboot access ... the problem is than when i run 'sudo fastboot -w' in order to perform a wipe, the linux command hangs the tf300t after having erased and formatted the userdata partition (first one in the wipe process) !!!
Also, flashing system or recovery using fastboot works but i don't have the blue progress bar during the operation and the 'sudo fastboot reboot' command hangs the device ... for example if i run 'sudo fastboot flash recovery twrp.blob (i use the 42 version not JB or ICS one) i have a successfull output BUT fastboot is unable to reboot my device and when rebooted after pressing the power button for 8 secs i am back in CWM 6.0.2.3
I've noticed this output when booting the tablet to the bootloader menu : 'key driver not found booting os' and i've no clue about the meaning of this message => it seems that if i successfully flash TWRP this message will disappear ...
Any help would be greatly appreciated,
Have a nice day
I've exactly the same problem!
I tried to:
fastboot -i 0x0b05 flash system blob
fastboot says ok, but I can't reboot by:
fastboot -i 0x0b05 reboot
fastboot says ok, but nothing happend.
On reboot the pad show the CWM interface.
I tried this:
Reboot the pad. When the pad activates the usb port, I tried: adb reboot-bootloader
Then the bootloader interface is shown.
A cold boot does not work.
I need HELP

Hi, posting just to let you know that i had to make a RMA for my device which was still under warranty => Asus fixed it free of charge
Best regards

I can't think of any particular posts, but I've seen this scenario around in these forums before. Have a search around.
Hi I have been reading a ton in the forums trying to figure out how to fix my tf300t. A few days ago I updated to the newest CM 10.1 nightly and when it restarted it was stuck at the Asus screen. So I have been able to hold vol down button and get to a screen that says
RCK Android [usb symbol] and Wipe Data
I have fastboot access and thought I would try to fix the problem myself by following instructions on another thread
"pyovue - If you have ADB access then unbricking it should be easy as you can push and edit any file on the system with it as well as fastboot? Or can ADB & Fastboot not mount (not just the sdcard) anything? If you don't care what happens to your tablet MB, then try this....
fastboot -i 0x0b05 erase system
fastboot -i 0x0b05 erase recovery
Then reboot (this should rid you of your bootloop to recovery and nothing should start)
Then download the stock ASUS Rom (from ASUS, look under Firmware)
Then try sending it with fastboot -i 0x0b05 flash system blob (you will have to extract two zips from the firmware files until you get to a file called "blob" then put it in your fastboot)
I almost guarantee if you have fastboot/adb working there is ALWAYS a way to fix it... only a hardbrick is impossible to fix.
"
I get cannot load 'blob' so I tried
fastboot -i 0x0B05 flash recovery recovery.img
seeing as I already had the recovery.img from when I first unlocked, rooted, and put cm 10.1 on it
please help I have no idea what to do and thank you in advance <3

What's the question again? If you have fastboot, you can always flash the system blob from your PC. Or you can push the rom (zip) to your internal storage, turn it off and on again. If you select rck on official recovery, it should look for the zip file on its own and proceed to flash it. If you have custom recovery, get to it and flash the same zip file. Make sure you have the right recovery for the rom though. Good luck.

Get back to bootloader (3 icons) and then try this command on your computer:
fastboot devices
if it will detect anything then you can try erease procedure by @Buster99 :
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
then after clean memory flash fresh official JB downloaded from asus website (unzip file untill you will have file called "blob")
fastboot -i 0x0b05 flash system path_to_blob
example:
fastboot -i 0x0b05 flash system c:\android\blob
this would take like 5 minutes, then:
fastboot -i 0x0b05 reboot
and you should be back on stock
I had slightly different issue - TWRP flash failed and I had only android booting - even after manually flashing recovery again via fastboot
this clean swipe got me going again - upgraded to 5.1.1 and set it up again

I'm having the exact same issue.
I can occasionally get into the bootloader, but when I try to get into TWRP it will show the logo page and will immediately restarts.
Following the link you sent, I tried the adb devices prompt, but it showed up blank. Do I need to be in TWRP for adb to work? When I try to get into TWRP it just restarts.
Not sure what my options are when the only screen I can get into is the fastboot.

If you can get into fastboot yours is a very different situation. But let me answer your questions first.
The linked method works if you have adb access in TWRP - however briely. Even if TWRP loops you should have adb access at some point (open Device Manager and watch for changes).
If TWRP is just bootlooping very quickly you may be out of luck but I have seen cases where a little window of adb access and careful timing of the commands let people push the file to internal and insmod it. But that depends on the nature of the bootloop, the skill of the user and persistence.
Now, if you have fastboot access you don't need any of that. In fastboot you have a pretty powerful tool to wipe and format partitions, flash the Asus blob if all fails, but you quite a few options....
If you can get "only occasionally" into the bootloader I would not wait much longer but perform a full wipe of the major partitions and flash the Asus system blob, returning the tablet to stock basically and giving you a fresh start.
We call it a @Buster99
Download the latest Asus firmware from here: https://www.asus.com/support/Download/28/1/0/11/fq2B3oq64av1O95u/8/
Extract it twice and copy the blob into your fastboot directory.
Issue these commands in fastboot one by one:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system blob
fastboot -i 0x0B05 reboot
Good luck!
Thanks Berndblb. I downloaded the Asus firmware and was able to get the blob file.
But I'm fine with totally starting over and trying Buster99, but I'm still unable to get the ADB to see the device.
I've gone through the beginners guide to root and flashing a custom rom again, but I still can't see the device when I type in "fastboot devices".
If you have any advice or a guide on what I need to do get where I can use ADB to erase everything and start over again.
i cant do anything the tablet starts - shows asus logo-go to TWRP logo screen - restarts (all in 32 seconds). Any other sugestion? if i dismantle the tablet ? or anithing else?
Thank You

Either you do not have the correct driver installed or your usb cable is not original but a cheap "charge only" knockoff or try a different usb port or you are not open the cmd prompt from the fastboot directory or your usb port is busted.....
I don't know how to troubleshoot that from here....
Please search the TF700 forum or google "fastboot driver problems". That problem is so common, I really do not know what to add to advice that's out there a hundred times over....

You can always install a new r used mainboard, but that's the only reason to open it up....
Sorry man, if you do not have adb while the recovery is looping or starting up and you cannot get into fastboot, there's nothing you can do.....
Except for the really crazy and desperate "throw away reason" stuff of course. Like stuffing the tablet into the freezer in an airtight bag for 30 min, then try to boot it......
Thanks Berndblb, I was able to get through the Buster 99 instructions above.
Per the last step I would have expected the tablet to reboot, but that did not happen.
When I restarted it I got the following error when I tried to load Andriod "unrecoverable bootloader error".
I used the following file from the Asus website US_epaduser10_6_1_14_10_UpdateLauncher, based on the fact that my bootloader shows the tablet as "US_epad-10.6.1.14.10-20130801". Hopefully I used the right file for the blob file.
I've attached what I have from adb for the system flash blob and reboot. I tried to screen shoot it in a better format, but that didn't work.
Hopefully someone will be able to take a look and direct me in the right way to get this working again.

You used the correct file but I see a mistake in your command.
You put a space between the dash and the "i" in your command: fastboot - i 0x0B05 which is a command fastboot does not understand so it shows you the help file so to speak.
It is supposed to be fastboot -i 0x0B05.
See the difference?
Try it again and welcome to the world of the command line
A thousand thanks Berndblb. I was able to get it flashed and it back to the original firmware. Thought for a while, it was a total loss, so your advise was a big help.
On another note, I was having this issue with multiple custom roms, which leads me to believe it a hardware issue.
If I press on the screen too hard or lift it in a different angle, it will freeze up and try to reboot.
I was just able to get past the initial setup, but once I lifted the tablet up again, it did the same thing and froze.
I had basically been stuck, just using the tablet for strictly steaming purposes and leaving in on a table.
If anyone has had similar issues or has any insight let me know.
My wife is asking for a new Ipad if we can't get it to work properly, I'm still trying to convince her to stick with Android but this tablet isn't helping my case.

damn i feel so used
grats on getting it to work again.
in regard to the troubles you are still having: is it in the Keydock or without, also a possibility that the display has an issue with the digitizer and shortens out.
cheers
Buster
I typically use it without the dock. Haven't put it in the dock in a while. Yea I was thinking the same thing where maybe something is loose inside.
Short of changing out the whole digitizer, do you know of any trouble shooting I can do if I open it up? If it keeps doing this, the tablet itself isn't worth using often. I did have a gumdrop case on it most of the time. I've got a toddler, so wanted maximum protection for it. Maybe it overheated or something?
Check out some tear down videos on YouTube and iFixit, then open it up and check all connectors you can get your hands or tools on. It does sound as if you gave a connection shorting out.

I also got into a bootloop situation and was unable to connect via adb (adb usb gave me "error: device not found") but fastboot was ok. So I tried the @Buster99 rescue. Unfortunately it failed at the flash system blob step. It gave "FAILED (data transfer failure (unknown error))...".
It's been too long since I used adb and fastboot. Lately my TF700T had become erratic, unstable and experiencing sudden reboots so I wanted to format data and do clean re-install of KatshMallow #29. I also had discovered that the digitizer had developed a blind-spot, actually more of a whole blind column of about a quarter inch wide, giving me problems swiping a TWRP button to unlock the screen. So, I went to change TWRP's screen timeout setting (TWRP 2.8.4.0 Kang) to max when suddenly it rebooted into a system bootloop. Going to TWRP would go to bootloop again at the TWRP splash screen.
Alas, I must have forgotten to set the USB debug mode after the last flashing as I am now locked out of adb. That's how I got into this unfortunate situation.
Any ideas, short of replacing TF700T's mb? Looks like this is the end of a long journey with my TF700T! :crying:

Did you ever get it fixed? I'm in the same situation. Can't enter recovery or fastboot. Well, I entered fastboot once, chose recovery, now it boot loops straight to recovery. This sucks. Tablet worked fine for months.
If you can't boot into fastboot and you do not have adb access when in recovery, you're done. Nothing left to do.
You did not mention if you are unlocked. With a locked bootloader you can't do anything even if you have adb in recovery or if you could boot to fastboot. Sorry
It is unlocked and rooted. I see something showing up in Device Manager, only it says Google Nexus ADB interface. I can also enter the other mode with Power and Vol Up. This mode holds, however, not sure if I can do much from there.
Now I got TWRP screen stuck, so at least it's not looping. But adb commands don't produce any effect.

What do you mean? APX? No, that does not help you

With TWRP booted, do you see the adb recovery interface in device manager and what do you get with "adb devices"? Do you have the drivers installed?

This is the only thing I see in Device Manager: Google Nexus ADB interface. I installed the Universal Drivers.
When I type adb devices, I get nothing.
Well, this one time I got this:
adb devices
List of devices attached
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
So I saw that timduru posted the files for Nougatella 7.1 and couldn't wait to join the club. It has been a while since my TF700T has been upgraded. I had TWRP 2.8.4.0 so I wanted to upgrade to the latest version. Mistake #1!!!! I went to TWRP and got the img file put in on my sd card and installed in through the TWRP recovery. Now I get the RED unrecoverable bootloader error 0x000000. I can't get into the recovery but the tablet boots up into KatKiss without issue. I tried the TWRP app as well with no luck. I also can't get fastboot with adb fast boot working.
Windows 10 32bit
Asus Sync installed
Minimal ADB and Fastboot installed
USB debugging checked in settings
Any help would be appreciated.
Thank you.
My apologies I just saw that this is in the TF700 General Thread not the Help and Questions section. Moderator is this something I can move or do you need to do this? I did a quick search and nothing came up, but also having IE issues loading this site right now. Again thank you all!
It took a good 8 hours but I was finally able to get my tablet up and running. I took the advice of several posts and used their concepts to find the solution.
No ADB/Fastboot issue. I uninstalled all instances of ADB and all the drivers that referenced the device. I also removed Asus Sync.
Post by Accord281 [solved] Need Help: Can't get ADB to recognize device, there was a reference that people had good luck with the Google Driver. I installed Android Studio with SDK manager. I went in and then installed the Google Driver as well as the SDK manager for the stock ROM version (JB).
This still didn't work, so I reread the post and several other as well. I noticed that the recommendation was to set the USB connection to Picture not File. So I did this and ADB was working. Problem #1 checked off.
TWRP error was next. In the post by kansasboy001 Help Unrecoverable bootloader error. He posted a solution form "Buster" which worked spot on. See below.
This is the ONLY solution for this problem, worked great for me.
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:
C:\>fastboot -i 0x0B05 flash system c:\adb\TF300t\blob
erasing 'system'...
OKAY [ 1.695s]
sending 'system' (800935 KB)...
OKAY [133.121s]
writing 'system'...
OKAY [153.973s]
finished. total time: 288.789s
im now setting my tab up to get back to CM (which initially caused this sh1theap due to autoupdate error, same as my A700 got bricked )
hope i could help you out!
cheers

Finally I was able to flash TWRP 3.0.0 in ADB. I also followed the post from lj50036 [twrp 2.6.3.2] [read me]. This seems to still be an issue with TWRP and the TF700T. I followed the code and it took less than 10 mins to format data.
Thank you to timduru as well as I am enjoying your build as we speak.
