I've a stock Lite-On dvd drive (74850) and i wont dump a full stock firmware with MRA hack before flashing.
But i've a problem to send the drive in vendor mode (0x72 status). With the switch in OFF position the drive is recognized good by jungleflasher, but in ON position (22 ohm resistor to ground) i receive 0x80 status ever.
I followed the official Jungleflasher guide: Power on the drive in OFF mode (properties ok), power off the drive and switch to ON mode, click Intro, then yes and power on the drive: 0x80
I tryed with 20, 18, 15 ohm resistor also, but 0x80 ever.
All soldering and cuts are good, i tested its with a multimeter.
Before to attempt the MRA hack, i successfully obtained dummy.bin with the RS232 probe.
What's wrong? Which is the cause of the 0x80 status?
