I OC'd my BTC 4012 (MT 1508E chipset) with the 4816IM firmware .HEX file and every thing worked well except that it wouldn't overburn any more.
It would continue TAO multisessions no problem but on a DAO96, 2/XA mode overburn it would first fail to fill the drives buffer just out of lead in hanging the whole system for about 15min and then give a "Power Calibration Error".
I know Power Calibration Errors can be media related but I have only changed the firmware not the media. Any clues? I've had to flash back to my original backup. I have heard other people (cmr2003x) talk of sucsess with this OC so it's got me stumped. : (
Now I was a little conserned that that 4816IM Firmware .HEX was smaller than my original 894KB vs 1077KB. Could this be a problem. I used mtkflash 1.55 ("mtkflash 2 w 482s.hex"), mtkwinflash, and the BTC Flasher and got the same result each time. I also tryed Nero 188.8.131.52 and 184.108.40.206 on 2 different OS's and still no joy. Can any one please help with this?
