It’s been 19 days since ASUS released the much-anticipated Jelly Bean OTA update for the mid-range Transformer Pad TF300T. Transformer Prime (TF201) and Transformer Pad Infinity (TF700) users are still waiting for their promised updates, but it’s actually possible to get a taste of Jelly Bean right now on your stock, unrooted Infinity tablet.
Some very brave and daring users at XDA have learned that the official update for the TF300T can actually be installed on the Infinity: all you have to do is download the software package from the ASUS site, rename the file EP201_768_SDUPDATE, and place it in the root directory of your microSD card. It should then install automatically, although complete instructions can be found in the thread below.
So far, it looks like almost everything is working, with the exception of changing the tablet’s brightness settings. The resolution is also off a bit, since this firmware was not designed for a full HD tablet.
You should keep several things in mind before attempting this: if you are rooted, you will lose root. You will also lose your custom recovery. (You can easily get root back if your bootloader is unlocked, though – instructions can also be found in the thread below.) Finally, if you brick your device while attempting this – or you find it impossible to roll back to official firmware for the Infinity – you can’t blame us. After all, this wasn’t designed for the Infinity.
On the other hand, lots of people seem to have tried this and are having a blast playing around with it. I am planning on waiting for an official update (I’m getting impatient, by the way), but if you give this a try, be sure to let us know how it works out for you. And best of luck![xda-developers]
