Install Asus Transformer TF300 Jelly Bean Firmware on Transformer Infinity TF700
Last month, we brought you the news of Jelly Bean rolling out to the Asus Transformer TF300T. In response, there was a loud outcry from users of Transformer Infinity for not getting Jelly Bean on their higher-end device before or with the more budget-friendly TF300. Guess what? The TF300 Jelly Bean firmware fully works on the TF700 as well.
Almost all the features are working except for changing 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.
Installing the TF300 firmware to the TF700 requires you to perform a few additional steps. However, they are simple enough for anyone to follow—no hacking required. XDA Forum Member MysticMgcn has written detailed installation 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.
You can download the ROM and install it using the instructions provided at the forum thread.
