Just finished hexediting and testing
Here are templates for Ixtreme 1.6 for 83V2 and 93450 liteon firmwares
what you need to do is place your keys/serials on it and will work for sure.
use Jungleflasher or Hexedit, whatever

Dont ask why you got banned if you play Online with this firmware, its 1.6

I Just have tested on 2 consoles so its your call
