HTC Thunderbolt Gets Ice Cream Sandwich ROM [Download & Install]

HTC Thunderbolt ICSAndroid 4.0.3 ICS based ROM for the HTC Thunderbolt – still in the Alpha stage – was just recently released by RootzWiki forum member ProTekk. Being an Alpha 2, the one thing that is keeping this ROM from being used as a daily driver is the non functional radio. The camera is broken too, but that is something most enthusiasts can do without for a while for an ICS ROM. More on the ROM and how you can get it up and running on your Thunderbolt, after the break.

Stuff like, Market, Wi-Fi, Audio, Sensors, Capacitive keys, SU and SD Card are working on the ROM right now. So is the GPS, Bluetooth and headset.

This ROM is purely to play around with as per the developer and is not meant as a daily driver. So if you still wish to flash it on your phone just to get a feel of ICS, here’s how you can do that.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.

Requirements:

  • A rooted HTC Thunderbolt with ClockworkMod recovery installed. (If you don’t have it already, this ROM is not for you.)
  • Thunderbolt ICS Alpha 2.

Instructions:

  1. To begin, download the recovery form the link above and copy it to the root of your SD card.
  2. Now reboot into recovery and make a Nandroid backup.
  3. Choose install zip from sdcard and select the ROM.
  4. Once the file is flashed, repeat Step 3, but this time choose the Google Apps.
  5. That done, simply reboot the device.

That’s it, your device should now boot into the new ROM. For updates and queries, visit the forum thread at RootzWiki.
