4. Press "Wipe" and check all options except "Internal storage" then press the checkmark to continue.
5. Press "(+)" once again and select "Flash Zip or OTA" and locate and select the ROM. Leave "Auto-mount" unchecked under the "Options" menu and press the checkmark to continue.

The screen will turn black then display the contents of your system before beginning the flash. FlashFire will pause for about 1 minute while flashing the "system" partition. Once complete your device will reboot and pause on the Samsung splash screen for about 5 - 7 minutes before completely rebooting. Done!
Tip: for blazing fast speed turn off animations from Developer Options and reboot!
Known Issues:
- Wifi may not function. To resolve the issue...power down (or pull battery) before entering "Download" Mode then Odin flash the modem from Post #2.
Notes:

Notes:
