However, for beginners, you need to root your Transformer TF300T tablet and install a custom recovery. Please Google that up if you are unsure.

Just To Remember:

  • This Android 4.1.2 CM10 Jelly Bean is only for Asus Transformer TF300T and I am not sure if it will work on the other variants of the tablet on other carriers.
  • Make sure you have ClockworkMod recovery installed.
  • Make a Nandroid backup of your previous phone set up before proceeding – for just in case anything goes wrong.

Step 5 – Now to get in the Bootloader Mode. Turn ON the tablet while pressing and holding the Volume Down and Power buttons.

Step 6 – Follow the navigation instructions on the screen.

Step 7 – In ClockworkMod recovery, wipe data first. Then scroll down to “flash zip from SD card” and press the Power button to select it.

Step 8 – Press the Power button again and select “choose zip from sdcard”.

Step 9 –Now using your volume keys, navigate to ROM zip and select it using the Power button. Confirm the installation on the next screen and the installation procedure should start now.

NOTE: Perform this same step again for the Google Apps zip file as well.

Step 10 – After the installation completes, go to “+++++Go Back” and reboot the phone by selecting “reboot system now” from the recovery menu. The phone will boot now and it might take about 5 minutes to boot on your first time. So, please wait.
