How to Install Custom ROMs with Rootjoy

Step 1.
Download, unrar and install Rootjoy on a Windows PC if you haven't done it yet, then run it. You might need to disable your antivirus app for the period of the installation process, then set the Rootjoy folder as an exception.

Step 2.
Enable USB debugging on your phone and connect it to a USB port of your PC. - Don't use a USB hub.
For the first time you have to enable on your phone to be accessed by your PC. Check the screen of your device.
WARNING! Updating the ROM of your phone with Rootjoy will erase your user data. To get a perfectly stable system by this update, that's recommended to manually process a factory data reset before installing a new ROM.

Step 3.
Click on the 'Flash' button

You need a working internet connection.

Step 11.
Check the screen of your phone. The installation of your custom (or even stock) ROM is starting.
The progress bar can be stuck at 50% for a long time but don't be afraid, the installation process is running smoothly in the background. It can take for up the 10 minutes.
