Following in the footsteps of One X, the mid-range variation of the HTC One Series, the One S, finally gets the CynogenMod 10 (CM10) based Jelly Bean upgrade. Thanks to the dedicated efforts of XDA senior member djsubtronic, the unofficial CM10 ROM based Jelly Bean update is now available to quench the thirst of Android fans with HTC One S device.

As The Android Soul notes, this CM10 version of Jelly Bean update is still under development and may not be fully functional or free from bugs and broken features. Custom features of CM10 are yet to be incorporated into the ROM to support full functionality of the device over Jelly Bean. However, users are welcome to test the software and help developers in further enhancing the software, besides finding bug-fixes.

For more clarity, here is the complete list of working and non-working features for the device.

Features Confirmed to Work

  • Recognises baseband
  • Hardware graphics enabled
  • Auto rotate enabled
  • Sounds on speaker supported
  • USB mass storage (strangely this works even though the phone itself cannot get into sd card)
  • LED flash (torch app)
  • GPS
  • Most apps

Features Not Working

  • Phone/network
  • Cannot seem to access sd card
  • Root access
  • Cannot turn on WiFi
  • Cannot turn on Bluetooth
  • Auto brightness
  • Headphones
  • Quite possibly everything else

Before you begin the installation steps for CM10 ROM, it must be noted that the guide works only for HTC One S and will not work for other devices.

IBTimes UK recommends you backup your applications and important data (bookmarks, contacts, SMS, internet settings etc) before performing the wipe procedure and do not forget to backup your APN settings, which can be restored later if your data connection fails after installing the ROM.

Here is the complete step-by-step procedure for installing CyanogenMod 10 ROM, courtesy of The Android Soul.
