please keep your mouth shut off if you don't know what to say.

YOU CAN FLASH UPDATE FILE FROM ASUS WEBSITE WITH TWRP 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.

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

Flash zip file from asus web site it really works!

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.

Re: [GUIDE] Update/Recovery/Root Android 4.2.1 on Unlocked Devices

You can. It is normal that it says that there is no operating system installed, because there isn't. When you flash the Asus firmware it will flash a blob file. That blob file contains the system and it will only install it once you reboot your tablet. Ignore that warning and reboot, don't be afraid ;) Once you do, a blue bar will appear bellow Asus logo, that's when it is actualy flashing the OS.

I will update the main thread with the info regarding ignoring that message.

Do you have the correct drivers for the device installed on your computer?

TF300T doesn't support 64GB cards by default. You will need a custom kernel for that. I think the one CleanROM uses has 64GB support, but I'm not sure since I don't have one of those.

The fastboot method works for us Linux users as well.

Setup:

Instead of downloading the fastboot files provided in the OP, I had to download the entire adb-bundle for Linux. I extracted it to my home folder (you can place it anywhere you want), opened a terminal and changed directories until I found the folder with the adb and fastboot executables (platform-tools on my machine). from there simply type the following to make sure adb is working:

./adb devices

If you get an error about libncurses.so.5 not being found, follow the directions here.​

If the above command returns something similar to this, then you may proceed

root@debian2:/home/kenny/adb/sdk/platform-tools# ./adb devices
List of devices attached
C9OKCT026709	device

Installing 4.2:

In your terminal on the computer, type:

./adb reboot bootloader

Use the volume down key to select the USB icon and then volume up to select it

Type

./fastboot -i 0x0B05 flash system blob

, hit enter and wait until it completes

Reboot your tablet:

./fastboot reboot

or hold the power button for 10 seconds if the command doesn't work

You should now have Android 4.2 installed

AWESOME guide! One thing I would add, though (I found this one out the hard way) is that if you have your files on a UHS-1 microSD and are using the TWRP method, TWRP will be able to see the files, but won't be able to move or install them, so you'll need to load any files you're installing (for instance, the update file or CROMI) to the internal storage or a slower microSD. The UHS-1 cards WILL work in the OS itself, just not in recovery.
