As far as i remember (been a while since i last did a benq) you can just connect up and load up jungle flasher, the only issue i can remember is getting it into vendor mode (ie being able to read / write to it) but that depends on what chipset you have in your pc, i would say connect it up , start jungle flasher and follow the steps in the jungleflasher manual, if you come across any issues or it doesn't go exactly like it says in the manual then update on here with any issues you are having
