Unofficial builds of CyanogenMod 10.2 are available for HTC One.

Recognised XDA developer, codeworkx has shared CM10.2 custom builds for HTC One users. Besides, the developer has shared easy tutorials to install CM10.2 featuring Android 4.3.

HTC One users, who wish to update their devices to Android 4.3 using unofficial CM10.2 build, may follow our step-by-step guide.

IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Users are also advised to ensure that their devices meet following requirements.

Pre-requisites

1) Install USB Drivers for HTC One to transfer files between the Android device and computer.

2) Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there, navigate and click on Development option and check the USB Debugging Mode.]

3) As the tutorial is likely to wipe out all data of the phone, create a backup. If the device is having any custom recoveries such as ClockworkMod/TWRP already installed, then backup data using the recovery.

4) The HTC One should have above 80% of battery charge.

5) The phone should be rooted and have ClockworkMod (CWM) recovery installed. Click here for our guide to root and install CWM/TWRP recovery on HTC One.

6) The CyanogenMod 10.2 builds work only on HTC One M7 (GSM version). Installing this on any incorrect variant might brick the device.

7) After flashing the ROM if the device gets stuck on Booting animation or experience boot loop then perform wipe cache partition and wipe dalvik cache five more times and then reboot the device.

8) Users are advised to give five to 10 minutes to the ROM once the device boots up for the first time to settle everything for a better user experience.
