Important Note: Although, we have taken the ROM link from a very reliable developer(XDA-Forum), yet go for this upgrade at your own risk as neither this site nor the author would be responsible for any problem in upgradation. However, this happens rarely. Also you would lose warranty of the hardware(if any).

The upgradation Process has been divided into two parts:

  • Pre-Upgardation.
  • Final Upgradation.

Please follow all the steps given below in the order they are given and donot skip any step in between.


Follow these steps with a little care. If you have any problem, feel free to ask-

  1. First of all check the phone version. It should be HTC One S only (Check at Settings> About Phone). Do not upgrade if you have some other version.
  2. We advice you to take a backup of your existing ROM by using Nandroid Backup and Restore App from XDA.
  3. You can also take backup of some important data such as SMS, Contacts etc.
  4. Make sure that your One S is at-least 85% charges. If it isn’t, we advice you charge your phone first.
  5. Next, disable all the anti-virus on your Device. Also uninstall all the Kies from your computer.
  6. Now enable USB Debugging on your cellphone (Option available at Settings > Applications > Development > USB debugging ).
