a brick occurs when the person flashing has no clue of what hes doing and basically ruins the dvd drive. most often occurring when the flasher thinks he as obtained the orig.bin and erases the fw off the drive but never did actually obtain the orig.bin. so he is now left with a 400 dollar paper weight.
so if a person flashes drive with say c4evas 1.4 firmware on a hitachi drive 59 , and it goes smoothly(was and now drive both have same key, )
no problems during flashing....
then maybe if a drive isn't working after said procedure, (open tray message)
drive isn't necesarily bricked, could be a laser problem?
i guess it could be a laser problem, but if it didnt have this problem before, then idk, bc flashing the drive wont change the laser. that could be caused by crappy media, but if your getting the message with originals, then idk what you did wrong.
