[TF300TG] For all who had received a brick after updating on the last firmware

[aLkRicha]

For all, who have a brick.

To solve the problem, you should do next:

1. Download the original file of firmware.
2. Get out from the archives the BLOB file.
3. Put it in the directory with adb and fastboot.

Next, there are few solutions to the problem.

The first way:
1. Boot into recovery or bootloader (if you can)
2. If you can't boot into bootloader, boot in it with command

adb reboot bootloader

3. Now you should install firmware. When you are in BOOTLOADER you can do this command

fastboot -i 0x0b05 flash staging blob

Now, even after command line say @ok, DON'T reboot your tablet. You must wait until you see progressbar on the screen and in will be 100%.
4. Next you shoul flash recovery. DOWNLOAD Flash it with command

fastboot -i 0x0b05 flash recovery twrp.blob

after that you will see msgs like "sending..." and "writing.." wait about 10 minutes after last msg. And reboot your tablet in bootloader with VOLUME DOWN + POWER
5. See in recovery if partitions are mounted and have or not zero sized internal memory.

Thats all. GL. Maby write smth else in this thread.

do you mean 100% written within the progress bar ?, cuz all i have is a filled progressbar with nothing within it , i've been waiting for about 10 mins , how long does it usually take ?

if you have fully filled progressbag - that's i mean 100%
it's good and ok
do next steps.

This should really be in the general section. Still a good find though.

i also haven't USB icon. It's normal, go to the next steps.

still bootlooping , same thing as yesterday , twrp recovery is working , all the partition and data are there , tried restoring my Nand backup ,again ! , bootlooping.
everything was working fine before , except for some of the sensors, (only affected some games like temple run 2 ) , so i said "hey , i have some free time , let's revert back to stock to see if i can get those sensors back on, WHAT COULD GO WRONG ! " , and here i am, wasted a day and a half trying to fix it , and now i'm really tempted to buy a sledgehammer. anyways thanks for your help : ) , you've been more helpful than others.

Fastboot protocol will start automatically when you connect your TF300 to your pc through usb cable when in bootloader :good: its the property of 4.2 bootloader

so.. if all your partitions are working now, why you don't flash rom from recovery. and did you do HARD formating of all partitions??

That's right!

i did try that , tried flashing cm 10.1 , tried restoring my previous Nandbackup , nothing , with those custom roms , the tab doesnt go beyond the boot screen (with nividia logo) , with the official firmware it goes beyond that to the silver asus logo and the rotating circle

and what is after roating sircle? Try to do all points from the 1st post.

 

[ningen90]

nothing , it's been stuck on this screen for more than half an hour , i did all the steps exactly like the first post(which i already did yesterday , but i did it again anyway ). btw on the boot screen , in the upper left corner , it says "keydriver is not found , booting os " what does it mean ?

khm... try this:
go in recovery, run adb. paste

adb shell

next, if this command is successful paste

dd if=/dev/zero of=/dev/block/mmcblk0p4 bs=100 count=1

and

dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=16 count=1

and go on 1st post. if it's good it is good if not.. go to the recovery and download in in your adb folder. Perform 4 and 5 or 6 points, and perform 1st post

i'm not sure why , but apparently it's related to root , whenever i tried to reboot from recovery ,it would ask me if i want to install superSU but i always chose to not install it , this try i decided to install it , and Viola ! , it booted

thank you very much ! , (though the commands and executable didn't exactly work. adb isn't properly installed, so it's on my end ) but nonetheless , thanks , i probably wouldn't have done it if i weren't on this thread , btw , will be safe to flash a custom rom now ? , the last 2 days were excruciating , so i just want to be sure. are custom roms compatible with the new bootloader ? , i now this probably should be asked in the specific rom thread , but hey ! , it never hurts to ask

I dont know. I try to flash DEODEX rom, but it isnt started.. custom roms i dont try to flash. So, i decidet to stay on the original firmware with root.
