[Guide] Android 4.0 Ice Cream Sandwich Update for HTC Sensation XL

The Android 4.0 Ice Cream Sandwich update is finally rolling out for the HTC Sensation XL in Europe, bringing the “first ever 4.7-inch screen HTC device” up to the latest iteration of Android. Yes, it’s not Sense 4.0 but only Sense 3.6 as is the case for all pre-2012 HTC phones, but that’s a disappointment that probably doesn’t hurt much at this point. Other Android 4.0 features are included of course, such as better performance, enhanced data usage monitoring, an improved notification bar, and more.

The update has been made available for manual flashing by the ever helpful guys at the XDA community, and we’ve got a full guide that you can use to flash the update on your device, in case you don’t wish to wait for the update to hit your device over the air.

NOTE: The guide below is specially for those that have a custom recovery installed on their Sensation XL, as OTA updates do not work over custom recoveries. The process includes flashing back to a stock recovery, so read the whole procedure carefully.

Let’s take a look at how the Sensation XL can be updated to Android 4.0 Ice Cream Sandwich.

Compatibility

This guide is compatible only and only with the HTC Sensation XL. It’s not compatible with any other device and may render an incompatible device unusable. Check your device model in Settings » About phone.
