Toshiba Qosmio X505-Q860 BIOS update Invalid Opcode

[M1Lou]

I was attempting to update the BIOS for my Toshiba Qosmio X505-Q860. I upgraded the processor to the i7-920XM and installed 16gb ofG. Skill RAM, then was having an issue where it would randomly crash after a few minutes in windows 10 or opening a program. I've read that it can happen when the processor attempts to tubo boost with the voltage locked for an i5-430m. I have the Toshiba BIOS version 2.90 and the same setup as the person in this thread here. https://www.bios-mods.com/forum/Thread-R...d-bios-mod

I followed the BIOS update guide on this site using the PH1614 program on a USB DOS boot drive. I also tried Ahmed's guide here and still no dice. https://www.bios-mods.com/forum/Thread-H...GINAL-BIOS I renamed the wph file to Bios.wph for ease of use. I am not sure if that might be the problem? I am receiving an Invalid Opcode at 0013 0000 0296 0000 0000 0000 0000 0000 0100 0000 0000 7F00 00. I thought I bricked my system, but was able to pull the CMOS battery and restart as it was dead and even hitting the power button did nothing. The second time I tried it had no issues restarting. What am I doing wrong?

I messed around a bit to attempt to figure out what is going on. I tried winphlash as a last resort. It also won't update the bios. It says Image verification failed, Error code 142, required device of platform function is not present.

I solved the problem. I followed Ahmed's instructions in this thread using Phlash17 with this command: ph161700 /x /FORCE /O /C /S bios.wph. It flashed without issue and I now have the custom Bios working perfectly!
