Early last month, HTC announced the list of HTC phones slated for upgrading to Android 4.0 Ice Cream Sandwich (ICS) some time before March ends.  The HTC Evo 4G isn’t on the list.  Will it be getting official ICS from HTC?  We’re not sure.  Can you get ICS for your HTC Evo 4G unofficially? You bet!

RootzWiki developer deck has created a custom ROM of ICS for the HTC Evo 4G.  Despite being an old phone (released in 2010), the Evo 4G does have enough muscle for ICS.

Deck’s AOSP-based custom ROM is still under active development and almost all functions work, although some bugs or force closes may be experienced.  As of last checking, the developer has listed the following broken features: camera preview, gallery editing, and WiMAX.

If you want to have your first bite of Ice Cream Sandwich, read and follow our step-by-step guide on how to flash deck’s ICS ROM on your HTC EVO 4G.

Requirements

  • Download Deck’s ICS ROM here (ics-deck-evo-alpha7.zip, 101.46 MB)

  • Pump up your battery to at least 60% to make your device last throughout the entire procedure.
