Upgrade HTCmyTouch 4G Slide to AOSP Android 4.0.3 ICS Via ICSex Custom ROM


Published onFebruary 29, 2012

The HTCmyTouch 4G Slide is one of the few phones from T-Mobile’s arsenal that is getting the spotlight lately with the introduction of an AOSP Android 4.0.4 Ice Cream Sandwich build for the device. XDA Developer member rajzzz has recently released an enticing new brew of a custom Ice Cream Sandwich ROM called ICSex 0.2 for the HTCmyTouch 4G Slide.

Currently the ROM is still in its beta stage so expect a couple of bugs or so at this point. Since this ROM is based purely on AOSP, expect to have a “Sense-less” UI that pretty much resembles the original Ice Cream Sandwich that Google intended to be.

Speaking of “Sense-less,” the new ROM promises to give all the Ice Cream Sandwich goodness minus the bloatware and crapware that are normally present when installing stock ROM from OEM.

If you wish to try out the new AOSP Ice Cream Sandwich build, then continue reading to learn how you can install it on your HTCmyTouch 4G slide.
