Update HTC One X to Android 4.2.2 Jelly Bean via CyanogenMod 10.1 M3 ROM
HTC One X is among the lucky few Android devices to receive the latest custom build of Jelly Bean firmware - Android 4.2.2 - via CyanogenMod 10.1 M3 ROM. The M3 version of the popular custom ROM belongs to the M-series, which releases once every month with new features (unlike the nightly build with beta updates).
As XDA Senior Member Mustavalkosta notes, the latest CM10.1 M3 ROM features its kernel based on Synergye's KangBang kernel that brings a few tweaks optimised for the ROM's performance. There is still no word on the official release of the latest Android 4.2.2 Jelly Bean firmware from HTC. So, those who cannot wait for the official release can download and install the latest CyanogenMod custom ROM using this guide.
Key Points to Note
- CyanogenMod 10.1 M3 ROM and the instructions given in this guide are applicable for the HTC One X model only. Verify the device's model number by navigating to Settings > About Phone.
- Backup important data and settings on the phone by using one of the recommended custom recovery tools such as ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup.
- Make sure correct USB drivers are installed for the phone on computer (download HTC One X USB drivers).
- Verify the device has at least 80 per cent battery charge to prevent unexpected device shutdown (due to battery drain) during firmware installation.
- Enable USB Debugging mode on the phone by navigating to Settings > Developer Options (if device is running Android 4.0 or later) or go to Settings > Applications > Development (if running Android 2.3 or earlier). If the phone is running Android 4.2, 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 seven times to unlock or reveal the hidden Developer Options under Settings. Now, select the checkbox to enable USB Debugging mode under Settings > Developer Options.
- Ensure that the device is factory unlocked (not locked to a specific carrier) and rooted with CWM recovery installed on it.
- If the device is stuck at bootingor 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 at least five minutes before working on it.
