nothing is done in dos for hitachi you are being fed incorrect info.
hitachi flash only done in windows no dos flashing lol
if you are getting open tray errors and discs wont read perhaps you have fuxored your laser?
replace the laser and if you still get errors then replace the whole drive if you have orig.bin and key etc.
I doubt it's the laser, though. The drive only stopped reading discs right after the failed flashing attempt in Firmware Toolbox. I believe I picked the wrong option when I tried to flash....I believe I chose Direct Drive Flash >>> Flash Keys.
Also of note - when I put a disc in after putting the drive into mode B, the drive appears to spin for just a second and then stop.
well if that was the case then you have changed your drive key, nothing else, the drive would still play dvd movies just not games.
also the symptom of dead laser is the disc only spinning for a second
when you insert a disc the motor spins and the laser checks for a disc if it gets reflection it knows there is a disc and if there is no reflection it stops the motor as there is no disc
still wanna bet the laser is ok?
youd be surprised how delicate the lasers are especially when the drive they are in is moved around outside of the console.
but hey keep your head up ur ass and not take any help thats your decision.
