Robin Hoods Playground

i have a 8 serious and when i put a game in it it says open tray......can i restore the 8 serious original firmware back to it

and it seems like i dont have any firmware on this drive i have all the files for it so how can i put the original firmware on the drive using jf

i try playing a original game it says tray open

sounds like either a bad flsah or the key is wrong to me, open the dummy you pulled from the drive in jungle flasher and check the key is correct
