Key Points to Note

  • The CyanogenMod 10.1 M2 ROM and the instructions provided in this guide are meant for the HTC One S model only. Do not attempt this guide on any other device, as it may cause irreparable hardware damage to the device.
  • Download and Install the correct USB drivers for the HTC One S on computer.
  • Ensure that USB Debugging mode is enabled on the phone by navigating to Settings > Developer Options (if the device is running Android 4.0 or later) or go to Settings > Applications > Development (if the phone is running Android 2.3 or earlier). Otherwise, if the device is running the latest Android 4.2 firmware, then do the following steps:
    • Go to Settings > About Phone
    • Scroll down to the bottom of the screen and select Build Number
    • Tap the Build Number for seven times so that the hidden Developer Options is unlocked under Settings. Now, select the checkbox to enable USB Debugging mode under Settings > Developer Options.
  • Backup important data and settings on the phone to avoid unexpected data loss during ROM installation.
  • Make sure that the phone has at least 80 percent battery charge to prevent unexpected device shutdown (due to battery drain) while installing the firmware.
  • Verify that the device is rooted with ClockworkMod (CWM) Recovery installed on it.
  • If the device is stuck at booting or experiencing boot loop issues, then perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
  • Allow the newly installed ROM to stabilise for five minutes (after first boot) before working on it.
