Flashing is the process of installing new firmware or low-level system software. Flash the new custom ROM over the original ROM that came with your phone.
Begin the process by opening the ROM Manager and clicking “Install ROM from SD Card”
The downloaded ROM should reflect in the list. If it doesn’t, ensure you’ve put it into the root folder of the SD card.

The flashing process takes up to 10 minutes and then another 20 minutes during the first boot. Please wait until the process is completely finished. Once the phone boots, you should find yourself in the new ROM.
