[Transformer TF300T Q&A, Help & Troubleshooting] monogwai:
Well, i tried.

Berndblb graciously provided me with the 10.6.1.14.10 firmware (for a TF700), but the zip file was corrupted. I scoured the web and found nothing (save for broken links to asus' support portal), but i did find a 10.6.1.14.8 firmware on some webpage, and gave it a try. Didn't work. Got this in response: <see attachment>

Now I see several posts where folks mention having had to do the process multiple times; usually it's that they'd missed 'fastboot erase misc' in the instructions. I didn't miss any commands. Is there still the possibility I need to try the same process over? We all know what Einstein had to say regarding not changing one's process, yet expecting a different result...

Update: took a gamble and flashed twrp recovery (was originally having twrp bootloop) and it took! Got in, formatted all partitions, and flashed katkiss nougatella. Now the tab works again. Whew! Long 3 months.

Thanks to xda for all the archived posts here, and [MENTION=4968172]berndblb[/MENTION], who personally took time to reply to my posts. Good lookin' out, folks!

You should be trying to flash a new RECOVERY, not system

[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
No, he's trying to do a buster99 by wiping all partitions and then flashing the Asus firmware blob. If you get an 'unrecoverable bootloader error' that's pretty much your only option. The commands are ok but something is off with his fastboot setup - no idea what though. Unfortunately fastboot error reports are so general, they are useless.

I would try it in Linux, that would at least exclude all the issues Windows has with fastboot/adb. Maybe set up an old PC with Linux Mint or try a dual boot alongside Windows. Or even better, ditch Windows for good and run Linux :victory:
[Transformer TF300T Q&A, Help & Troubleshooting] Nektopoli:
Wont flashing the Asus firmware take him back to the Asus recovery console also? - NP

Hi, i have install Ubuntu and try it again. And i think i have found the problem l. ADB can't see the device. Fastboot yes, command lsusb see the devices, but ADB not.
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
That is normal. ADB only works when the tablet is booted into Android or the recovery (if the recovery supports adb and TWRP does). You have access to neither at this point, so forget about adb at this point. Fastboot is your only option. What do you get when you run the fastboot flash system blob command now?
[Transformer TF300T Q&A, Help & Troubleshooting] lalisek:
On ubuntu do it nothing. Only send command a then the same error message like in Windows or only sending and after 20 minut no change. After unplug usb again the same error mesage and error in SendBuffer
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
That is too bad! I assume the blob file is in your current directory when you run the command? Post the terminal window

Try adding the path to the file and sudo:

sudo fastboot flash system /your_directory_path/blob

You'll have to enter your password after the command which does not display in terminal.
[Transformer TF300T Q&A, Help & Troubleshooting] lalisek:
I have try it like you write with sudo and path of blob. I have extrackt blob to folder with fastboot. Password was good. I will post the window tomorrow, i dont have time today. Thank you for answers and again sorry for my english.
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
Sorry to hear it. I'm all out of ideas at this point. Seems fastboot is working on the PC side, but something is broken on the tablet side. I think your only option left is to find a new or used motherboard if you think it is worth it..

Good luck.

I'm sorry, but this looks very strange. What is shown in your fastboot window after putting in "fastboot device"? Does your device appear correctly?

What Windows version do you have? As far as I can remember [MENTION=3127371]Buster99[/MENTION] gave in his post a signal that Windows 8 sometimes sucks for Fastboot stuff.
[Transformer TF300T Q&A, Help & Troubleshooting] proza:
It shows xxxx Device

I am using OS X.
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
I think in your case only helps "Try & Error" as method. First of all check your USB driver. Maybe Windows 10 sucks sometimes as well. After that use another USB port of your PC. Finally try ADB instead of fastboot protocol.

It may also be helpfull to read all posts from berndblb and NP in this thread about driver and fastboot stuff. Start with post #480 upwards. Go ahead!

Hello,

The above will work only if you are able to access the FastBoot commands, in most of the cases we are facing we have access only to the APX mode (Reset + Vol up) not FastBoot (Reset + Vol Down.).

Thanks for sharing your findings though, hopefully if any one was able to recover his TF300T or TF700T from APX mode to share his findings also...

I suggest you follow up on this Thread:

This saved my TAB!!!!. I followed the steps to the letter. I tried everything else before i tried your method i even tried reaching out to TWRP channel but that didn't help. This was awesome find. How did you find out these commands? i didn't even know you could manually type them in fastboot.

---------- Post added at 04:04 PM ---------- Previous post was at 03:13 PM ----------

so i can prevent this from happening again, does anybody know if you use this method to flash to stock ICS blob, will this restore the bootloader so i can use NVFLASH??? that is the $$$ question.

if not is there a way to erase the bootloader and restore it to ics, so we can use NVFLASH??

I thank you for your help, believe me is really appreciate! Please have a look at the pics even if they're a bit blurry, but as per my previous post, if I am powering up normally, the tablet get stuck at the ASUS splash screen and nothing else happen. If I am booting in fastboot for each of the 3 options (recovery, rom or wipe data) at the end I've got exactly as follow:

Key driver not found.. Booting OS

I am able to connect the tablet via fastboot via USB, so the PC can recognize ASUTEK fastboot, but I am not able to launch any command like adb reboot bootloader, or adb devices as the devices is not found

Please let me know if you need something more

cheers

EDIT: just called ASUS support, useless as normal. They said, based on the S/N provided, the device has been locked by them so the only way to restore the tablet is replacing the motherboard, cost for the operation about 250eur....I don't trust them as I don't think they understood what I meant as hard brick....
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
hehe ok - first thing: relax :)

got that on my tf300 as well - so can't be the problem here.

when in fastboot, adb command won't work. do you know if on the tf201 the PIT changed fom 4.0 to 4.1? with the 300 they changed the partitiontables so a diffren't recovery is needed (just checked with twrp - there are jb/ ICS images ( http://teamw.in/project/twrp2/93 ). So you have to check first which one applies to your device.

What kind of recovery were you trying to flash?

Yeah: when in fastboot mode please issue in your terminal: fastboot devices. do you see your tablet there?

if yes: fastboot flash recovery twrpfilefromwebsiteabove.img :)

please document the result (rightclick in terminal, -> mark then with leftclick mark all text and paste it here)

ASUS Support is stupid as a box of rocks (german and UK alike) so I'm not surprised thats not that different with yours.

BTW : what do they mean with: the device has been locked by them?

cheers

Buster
[Transformer TF300T Q&A, Help & Troubleshooting] paura01:
I really hope so :P

Not sure what you mean at the bold statement. My ROM was the AndroWook with 2.5.0 TWRP recovery.

Either BLOB & IMG 2.6.3.0 recovery file with no luck

no

if yes: fastboot flash recovery twrpfilefromwebsiteabove.img :)

please document the result (rightclick in terminal, -> mark then with leftclick mark all text and paste it here)

YES INDEED!

Not sure either, I think he was referring about to unlocking the device, consequently you lost your warranty, but as stated above can't talk to much to a stone...
