Jungle Flasher doesn't work with windows x64, which is all I have...
I think a few of the reasons you're not getting a ton of help here is that a) this is a "Newbie Chat" question posted in "Technical DVD-ROM and Modified DVD Firmware Forum" and you haven't taken the initiative to actually try anything. If you look around there is a ton of videos and tutorials and forum posts about dumping/flashing liteons with iPrep.
In short and to do this without definitions or JF to r/w:
1) Prepare your iPrep USB stick without any firmware at all (or use an older 838 firmware as a placeholder) selected and click "create bootable"
2) Boot off your USB stick and just go through the steps for reading the Liteon but DO NOT erase/flash it. This will save several files to your USB stick including the key. I recommend doing this several times to make sure you have a real key and googling your key to make sure its legit
3) Boot back into Windows and, using Jungleflasher, spoof your LO83DUM.bin as source to the new target firmware. Save that CFW to your USB stick as LO83CFW.bin (or something like that I forget).
4) Boot back into your USB stick and flash using that newly spoofed firmware using:
flit 1234567 12345 w
The lowercase w means "just write". This should erase and write the new firmware.
Good luck.
