Procedure to Update HTC One with Jellybean 4.2.2 Android OS:
- Download the Jellybean 4.2.2 MIUI v5.0 Android Custom ROM Firmware Package from here to your computer. Once downloaded, connect your device to the computer with the help of original USB cable and place the zip file in your device.
- Turn off your HTC One smartphone so that it can be entered in the Recovery Mode via Boot loader mode.
- The Boot loader mode in HTC One X can be entered by pressing Volume UP Key + OK button, and holding both simultaneously press the Power Button. If the phone boots in the normal mode then you need to try again to enter into the boot loader mode.
- Up next in the boot loader mode, you need to select “recovery” so as to enter into the recovery mode. In recovery mode, select Wipe data/factory reset and Wipe Cache partition for clearing all the cache data present in the device.
- In recovery mode, select “install zip from sd card” > “choose zip from sd card” and then choose the Android revolution HD firmware package which you have placed in the device. Once the file is selected, it will take around 4 -5 minutes for applying the update.
