ASUS has been called many things, and it has even been described as quick and efficient when it came to updating its tablets, but the Transformer Pad Infinity TF700T tablet is the exception to that so-called rule.By our reckoning, and that of many other people, ASUS should have already updated the tablet to the Android 4.2.1 operating system.
Sadly, this hasn't occurred yet, and we have no way of knowing when, if ever, the company will carry out this task.
Not all is lost though. While ASUS's own development lab has been doing other things, a group of software developers from XDA have put together a custom Android 4.2.1 ROM.
Details about the custom update can be found here, and the full list of instructions, risks and drawbacks is available here.
And so we've reached the first pitfall. Since this is an unofficial upgrade package, it has a bunch of bugs, and it doesn't even get all hardware features to work fully.
For example, the GPS and the camera do not work, even though the update comes from the official Android Open Source Project code base.
The audio code had to be written from scratch too, although at least this aspect works properly.
Needless to say, most people should steer clear of this release, unless they have someone in their entourage who knows enough to try their hand at manual updates.
In fact, people shouldn't even think about applying this ROM unless they were successful in rooting their tablets.
Needless to say, installing this Android 4.2.1 release will void the product warranty and could very well render it totally unusable if a step is missed or botched.
For those who want to know exactly what works after installing the Android release, this is the list: 1. OpenGL graphics, Bluetooth/Bluetooth Audio, Sound, screen rotation, Wi-Fi and the SD card slot.
