Already happened with me!!! I've followed your tutorial blindly and had to sweat a bit to recover my tablet.

Change it ASAP.

Best solution to unbrick/flash is to go into fastboot and use

fastboot -i 0x0B05 flash system blob
fastboot -i 0x0B05 flash system "name of the update"

Did you unpack the zip downloaded from Asus?

Then you didn't brick, bud. What exactly did it do? Why do you think it "bricked".

please keep your mouth shut off if you don't know what to say.
YOU CAN FLASH UPDATE FILE FROM ASUS WEBSITE WITH TWRP [B]AND THERE IS NOT BRICK IN HERE
******
here is what i just did to update my tab to 4.2.1
-was running cleanrom 3.4.4 with twrp 2.2.2.0
-downloaded twrp 2.4.4.0 and flashed it with fastboot
-download 4.2.1 update file from asus website=> unzip this file to get the real file ( apparently, asus just put the rom.zip file into a folder, then zip this folder again, kind a stupid here ^^)=> put it in my external micro sdcard
- boot into recovery=> flash the updated rom.

It wouldn't flash for me either. I used your method of flashing the blob, then followed the OP's directions for flashing TWRP using the fastboot/TWRP files he provided.

Re: [Tutorial] Rooting and installing a recovery on Android 4.2.1 (10.6.1.8+)
What i have done
I download the firmware from asus and renamed to xx_epad-user-10.6.1.8.zip
XX is the ww or US you must rename this in the directory what you extract
Example WW_epad-user-10.6.1.8.zip
US_epad-user-10.6.1.8.zip
Then put it in the root of your sd card or on your root on the tablet
Then you can update
And you can root follow this forum.
I am on 4.2.1 and rooted
Thank for all who have this made it
Thanks

I did flash my asus with the zip from asus web page with no issues, I used TWRP 2.4.3
I un-zipped the file (just one time and without change the name) and I placed the next zip file to my SD card root folder, then I made a full wipe and intall the zip file from SD card.
Right now my asus belong to my wife, my youngest son and I because I can create users.
I made a backup of my apps with the asus aplication and I could reinstall all them after the update.

Good to go for me. TWRP recovery and rooted. Nice write up man.

You might add in there something about the new bootloader booting directly to fastboot now, no need to select the usb icon. Also maybe mention to make sure that the drivers get installed properly once you are in fastboot. When I booted to fastboot it had to install some drivers, so I waited for those to finish before I ran the fastboot command.

Installed TB and about to uninstall some bloat. Can't wait for roms to get updated.

Thanks again man.

I don't understand what your bricks are. Maybe you didn't wipe your tablet as you should? I updated to 4.1 and 4.2 via recovery and never had a problem.

I updated the topic with more info

Could you tell us what you did exactly?

Hey guys,
for example if I want to do a clean 4.2, if I wipe EVERYTHING in TWRP and flash the 4.2 zip will it work? I always do this on 4.1 but not sure whether it will work on 4.2
