[Transformer TF300T Q&A, Help & Troubleshooting] paura01:
If I am rebooting the tablet normally I am going to the ASUS splash screen and that's it.

If I am rebooting with Vol UP as above

If I am rebooting with Vol DOWN I am into fastboot but for each of the 3 choices I've got the famous red written error. I will try flash the ICS (does the IMG or BLOB file extension make any difference? At the end then, is it enough reboot the tablet with the power button only or there is any specific command to execute? Please not that either fastboot reboot and fastboot reboot-recovery would not produce any effect

[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
use the blob. and if its not working try the fastboot erase as mentioned in my earlier post and try to reflash stock rom.

Hi,

without fastboot there is not much that can be done sadly. only if you have an nvflash image of your device.

Could you tell a very very very easy process in order to get Nvflash IMG on my device? If my device could just get recognized in boot loader than I could go into fastboot, I have android 4.2 Asus stock firmware on it never been rooted or anything. When Ido Adb devices it ssays something along the lines of adb server out dated killing deamon or something like that so I am thinking it is the adb server how would I fix that also?

Stuck at erasing misc

Hi,

while using fastboot, it hangs ons erasing misc. This means I'm not able to flash the stock rom.

The tf300t bootloader isn't unlocked, the device wasn't rooted.

Anyone have a solution for this?

Tnx

D.
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
hmmmz without unlocked bootloader it will be a wee bit difficult to erase all partitions - hence the locked bootloader to prevent such things. if you still have fastboot/adb access you can still unlock the bootloader though - but bear in mind: your warranty will be voided.

the nvflash afaik has to come from your device. please check the nvflash thread for further information.

Cheers and thanks for this workaround.I can confirm this method working with CWM recovery stuck boot, too. I just unbricked a tf300tg half a hour ago and the little green robot is alive again.:good:
[Transformer TF300T Q&A, Help & Troubleshooting] lun7200:
Hello,

Thanks for this information. Unfortunately I can't give it a go because I am having trouble entering fastboot mode or adb. My TF201 has an unlocked JB Bootloader (asus method) but even though I presumed I flashed the correct TWRP (2.6) and my OCD made me double check it was for my bootloader but I am now stuck in a recovery loop. I cannot access the 3 icon menu and only the TWRP recovery. Since its not the correct recocery (as pointed out by another user in another thread) I cannot mount partitions or execute ADB Commands. I get the message error: insufficient permissions on my terminal. Is there anything im doing wrong? I tried to boot to fastboot using a method for the TF300 that included pushing the reset button with a needle with no success.

Thanks again!
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
did you try to flash stock via fastboot? should work with locked BL.

glad to hear :)

just reflash the proper recovery - as long as you dont format with the wrong recovery no harm should be done. try issuing adb reboot bootloader while in the wrong twrp - you should be taken into fastboot mode.

Thank you very much for this.

I had put my tablet aside for months checking the forum every now and then for a concrete solution. And yours worked flawlessly.

This should be wikified if it wasn't already. I'm adding it to my local personal wiki.

I don't know if there is a well-maintained wiki for Android and its devices. But I hope something like the Archwiki exists.

You quoted buster99's post - did you try his method? Those commands are all done in fastboot - but you don't know if you have fastboot access? I am confused....

Maybe you should post in detail what your situation is and what you tried....
[Transformer TF300T Q&A, Help & Troubleshooting] Exterminator77:
i am sorry i do have fastboot the problem i have is that i tried to update my twrp recovery from 2.4.4.0 to 2.6.3.0 and i think i got the wrong blob file also i did it with the terminal program with my tablet so all i am left is with the twrp recovery 2.6.3.0 which shows no data files or doesn't see my sd card also and no OS to go to maybe there is a way that i can force some files into the tablet it also saids waiting for device i have done alot of the commands that i have read here but no change maybe i am missing something it goes right into the twrp recovery and ask for a password i cancel but still the same deal not sure what to do at this point thanks for the help:(

Have you followed Buster99's commands. You have flashed an incompatible twrp - his method can recover from this but you need to be n the bootloader to do it. (not recovery)

[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
When it starts a new loop hold the Volume Down and Power buttons until the tablet vibrates twice or you see some tiny script and three icons. If you can get there you are in the bootloader menu and would have fastboot access. That would enable you to flash a recovery in fastboot.

Try and report

well i tried but no luck just goes right back to twrp recovery which i can not do nothing with also when i try to do anything with adb fastboot in windows it keeps saying waiting for device and stays there no change thanks again
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
beneath the volume rocker under the msdcard slot there is a tiny hole with the reset button.

use a pin/needle/smth pointy that fits and reset the tab while holding vol down.

otherwise, please provide a short video of what you are doing and the screen of the device. maybe that will get you help fastest.

[MENTION=4878287]_that[/MENTION] wrote this in another thread:

Quote: When the user chooses "wipe data" from the bootloader menu, the bootloader writes some information to the "misc" partition (mmcblk0p3) and starts the recovery. The recovery finds a command in the misc partition and formats (?) the data partition. When it is finished, it removes the command from the misc partition so that the bootloader can again boot Android. When it is interrupted in any way, after a reboot the bootloader will automatically enter the recovery directly.

The problem with this is if your recovery is broken or incompatible. I've read somewhere in this forum that the incompatibility is from enabling something called TF (Trusted Foundation) in the bootloader since JB, which requires a corresponding option in the (Android and recovery) kernel. If the kernel does not have this enabled, it cannot access the eMMC at all.

Now if your recovery cannot access the eMMC, you can't reset the information in the misc partition, and the bootloader will stubbornly try to boot the recovery to wipe data. The fact that not even the boot menu or fastboot works in this case makes this a hard brick. EndQuote

It seems something similar has happened to you and you are in this deadly cycle of booting straight into an incompatible recovery. I think the only way of recovering from this would be to find a way to wipe the misc partition.

This is way past my level of expertise unfortunately....
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
good explanation. but in the beginning when I had my trouble with my pad I had the boot loop. but I did manage through pushing reset and volume key to get to fastboot and once there you can erase misc then. honestly it took me in total about 3h+ of trying to get to fastboot.

BUT:

if you already have access to even the wrong recovery booting twrp has adb running and you can issue then adb reboot-bootloader which should get you to fastboot.

[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
If I understand his/her situation correctly the tablet boots into recovery but crashes immediately, boots again etc., so ADB access is probably out of the question.

I agree, getting into fastboot seem the only salvation.

When you did this, did you spend three hours trying to get into fastboot with the pinhole/Volume Down combo (which would indicate you have to hit them at just the right moment of the bootloop) or 3 hours trying all kinds of methods to get into fastboot?
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
3h fidling with the device. additional hours researching my prob. but yeah the goal was to get fastboot. and yeah it was annoying as fk since both my tabs had the same problem (cm 4.1 to 4.2 update error)

but if he/she has twrp without crashing/freezing adb should work. at least it's worth a shot.

Hi guys,

I've got exactly the same problem, the thing is that I can't acces to fastboot from my PC even though "starting Fastboot USB download protocol" is written on my tab. :(

I've got Asus sync drivers and SDK installed.

I think the NvFlash is useless since I don't have any backup.

Last thing, I don't use an official USB cable from Asus.Do you think it's possible this has an impact on Tablet recognition for the computer ?

Any more ideas ?

I really need my tablet, I'll go to a foreign country for 4 mouths, and I don't have a Laptop so for me, my Tf is essentiel.

[Transformer TF300T Q&A, Help & Troubleshooting] TeCKNeiC:
So I have tried BUSTER's instructions repeatedly. I do not know what is the problem with my tablet?! I am able to see my tablet on the host computer when entering command "fastboot devices" and I am able to use the "fastboot erase" command to delete some of the suggested partitions but when I attempt to use the command "fastboot erase userdata" I get a FAILED every single time. I think this is stopping me from then using "fastboot flash c:\blob" (rewriting this from memory so the exact command may be different than what I typed but at the time I copied the command exacly) because that also fails after i get the "ok" that it is being "flashed". After that "ok" is displayed and waiting extremely long while the cursor flashes on the host computer and the highlight around "RCK" stops blinking while it appears it is flashing but also FAILS after about 24786.01sec (usually a two hour wait) I get a "FAILED (Too Many Links)". What am I doing wrong, are my partitions fried or something? I see my tablet through fastboot so I feel that this can somehow be revived without have to send to the shysters at ASUS. Please advise, I miss my TF700 lol.

Seems like theres a lot of us still having the issue even after trying busters method..

now i see most of you are in the 4.2 (three option) bootloader whereas i used to have it now somehow im on the 4.1 (four options)

could this be my problem ive tried every method using windows xp, vista, 7, 8, ubuntu 12.04, ubuntu 13.10. installed naked drivers adb fastboot you name it.. i run all fastboot commands perfectly fine and when i get to flash blob it erases and sends but hangs on writing..ive tried the latest firmware the earliest firmware someone even had a blob from the original firmware that cant be downloaded from the asus website and still didnt work.... maybe theres a different partition needs to be wiped?!

this is killing me i want my tablet back soo bad!
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
some thoughts come to mind

1) did you use the asus cable?

2) did you use the 4.1 blob? go first with the last installed version and after its working update to latest.

3) what error do you get while flashing the blob?

4) were all erase commands prior to flashing successfull?

5) can you flash a custom recovery and boot into it?

-Buster
[Transformer TF300T Q&A, Help & Troubleshooting] schkeet:
1) yeah the original cable is all ive got its not broken in any way

2) i tried using the 4.1 blob i do notice there is a few WW editions missing from the website but theres US and JP versions...i live in toronto bought the tablet from best buy can i just use the US?

3/4) i follow all your erase commands which %99 work successfully... a couple times (ive tried this method countless times) ive hung on the erase recovery and the erase userdata where i get a message <waiting for device> after that i get no response from the tablet i can cancell the command but when i fastboot devices i get a bunch of ????????... other than that the erase commands always work and very quickly aside from the userdata usually takes around 20 seconds.

then i try to flash blob it says

erasing 'system'...

hangs here for about 10 min then says

OKAY [2.xxxs]

sending 'system'... <800927 kb>

i can leave it here for days with no change...a few times ive got a message i cant remember what it said but someone a few posts back had the same message.

5) Havent even tried to flash a custom recovery my screen was cracked and i have no touch to navigate the recovery which was why i loaded CWM arghhhhhhh!!!

By the way as soon as i select the usb icon when booting to fastboot the green highlighted area freezes at whatever shade of green it was at but fastboot starts and works seemingly fine...

thanks buster

edit i just somehow got this to work its been since october ive been pulling my hair out tried every method including this one probably 250 times and without changing a thing on the 250th try it just worked

wow i cant thank you enough buster guys having the same problem as me all i can say is use the right cord

i had a laptop running vista i loaded ubuntu 12.04 and instaled fastboot and adb and ran these commands it still didnt work till about the 15th try just stick with it and for refrence i used the earliest firmware available from the asus website

[Transformer TF300T Q&A, Help & Troubleshooting] f69m:
Not sure, which bootloaders you mean with v7 and v8. Check on the top-left of your boot loader screen for a version like 10.6.1.*, which should be the same as the version of the last Asus ROM you installed. For running KitKat ROMs, the version should be 10.6.1.27.5 or 10.6.1.27.1.

The easiest way to upgrade your boot loader is to install the latest Asus ROM via fastboot. Unzip the ROM twice and flash the blob.

[Transformer TF300T Q&A, Help & Troubleshooting] f69m:
Flashing from terminal is usually safe, though typos are dangerous of course.

And flashing the wrong recovery version is just as easy as via fastboot.

as long as you have fastboot all is reversible.

just erase recovery first then reflash the correct recovery.
