The Asus Transformer TF300T Jelly Bean firmware fully works on the TF700 device also. It requires only few additional steps. In this tablet almost all features are working except for changing the screen brightness, though that can be accomplished with third-party apps. Also, the DPI is set to 160 and changing it in build.prop seems to do nothing at the moment.

The XDA forum member MysticMgcn has written the detailed instruction guides for rooted and unrooted devices with locked or unlocked bootloaders and stock or custom recoveries. You will lose root and bootloader unlock by installing the ROM. However, the bootloader can easily be unlocked and the device can be rooted after the update using the instructions provided.

Follow the given below instructions to download and install the ROM in Asus Transformer TF700.

WARNING: We and even the developer won’t be held responsible for any damage that takes place to your device while following these steps. So, root your device at your own risk.

Method 1: Locked/Unlocked Bootloader with Stock Recovery and/or Root:

1. Initially, you need to power off your tablet.
