Owners of the HTC Rezound, a new Ice Cream Sandwich treat has been made available to you today. We know that an official update to Android 4.0.3 is in the works for this device, but if you want to get a taste of something close to that final build ahead of time, this is your chance. The source is calling it “official” yet a “release candidate” so they are clearly a bit confused as to which it is. What we know is that it is a full ROM, so this will almost undoubtedly wipe your entire phone. Approach with caution.
This will bring you to software build 3.13.605.7, Android 4.0.3, and Sense 3.6. It also has new radios.
Instructions:*Your bootloader needs to be locked. If you unlocked using the HTCDev tool, this won’t work.1. Download the file from above and rename to PH98IMG.zip.
2. Place the file on the root of your SD card and power off your device.
3. Reboot to bootloader by pressing Volume Down and Power.
4. Once in the bootloader, the process will start automatically with on-screen instructions.
5. Enjoy ICS.
