Common problems and Frequently Asked Questions
JungleFlasher tells me “Cant install portio32/64.sys driver”
If you are running any OS other than XP x86, then you must run the
program as Administrator, see here for explanation how!
JungleFlasher tells me “No Com ports found during enumeration”
The LiteOn DG-16D2S 74850c Drive requires the utilization of an RS232
Serial Adapter to obtain the DVD Drives key (Unless you are using a Probe
3/PMT). Unless you are doing one of these drives, simply ignore it and
proceed.
If you no longer use COM ports (With PMT there is no need) then you can
stop Jungleflasher from Enumerating COM ports by setting DoCom (in
registry – see advanced user functions) to the value 0
When using X360USB Pro – the drive reboots when trying to dump the drive or
JungleFlasher seems to Lag OR I get erroneous issues
Try changing the USB cable you are connecting the device with / failing that
try another USB Port.
