Moreover, the HTC One device where the new custom CM 10.2 ROM will be installed will be able to have a better battery life,  enhanced speeds and better performances, as well.
The best is that, this guide will provide you the official release of CM 10.2 and not a custom one. So, this custom system is coming directly from the Cyanogenmod team especially designed and optimized for the HTC One device.
Before to learn how to install the CyanogenMod 10.2 Android 4.3 Jelly Bean update on HTC One, you will first have to take care of the prerequisites that are required to be followed before to begin the installation process of the new system.
The HTC One device needs to be a rooted device. You need to root the device because a custom ROM firmware can be installed only if the system is unchained.
Important: when the root access is gained then the warranty of the HTC One device will be void.
So, knowing this, you need to be careful when performing the installation operation of the new CM 10.2 firmware to the HTC One device as you don’t want to damage your smartphone while the warranty is voided.
If you want to restore the warranty of the device, you’ll have to downgrade the device to stock Android Jelly Bean operating system or to update it with the latest Android 4.4 KitKat firmware.
Note: when the HTC One device is a rooted device you have manually install the official Android 4.4 KitKat on it.
After you gain the root access on the HTC One device, you have to flash a custom recovery image on it. As you probably know the HTC One device comes with a stock recovery image out of the box, but unfortunately this stock recovery cannot be used to install a custom ROM like CM 10.2 firmware.
So you have to flash the CWM recovery or any other custom recovery image in the device. We will use in this step by step instructional guide the CWM recovery. The CWM recovery image can also be obtained via Google Play and installed after the root access is gained.
Backup all your data stored into device’s internal memory, the installation of a custom ROM is a risky operation that’s why you have to be sure that your data are safe.
When the new CM 10.2 Android 4.3 firmware is installed a wipe operation is being required. So, your data, personal info, accounts, documents, images and everything else that is stored on the internal storage device’s memory will be corrupted or deleted.
So, knowing that our advice is that is very important to make a complete backup. For this,  you can save the current ROM by creating a full NANDROID backup.
During the flashing process a computer will be required, the HTC One device and the device’s official USB cable.
Ensure that the security tools such as antivirus, firewall, antimalware, which are installed on the computer and the device should be disabled or uninstalled.
Enable the USB debugging option on the HTC One device by following the next path: “menu -> settings -> developer options”
Make sure that the device’s battery has enough power left, the charge level should more than 65 %, because the flashing procedure will take a few minutes and if there isn’t enough power the device can take a forced power off in the middle of the process and this action can brick it.
