Bricked my P775TM1?

Hello there,

i think I made a big mistake..

I was trying to update my bios using the official clevo update https://my.hidrive.com/share/yze8mg-wf8#$/BIOS and EC Firmware/CLEVO/P_Series/P7xx_Series/P7xxTMx/P7xxTM1(G)

 

ec worked fine but the bios flashing gave me an error - rom id not matching. So after a lot of google research I decided to edit the flashme.nsh with a /x command that would tell the Afuefi to not check for rom id. After that I was able to flash the bios, with the information that it would be a forced update and it is recommended to not continue.. well smart me decided to do it anyways. I was so smart thinking well if it fails I just reset cmos and I’m back to normal… not realizing cmos would be the new version then.. 

 

end of story I have a black screen now, pc starts, fans spinning but black screen. Tried everything, with/without cmos battery, ram, graphics card. Nothing happens… it starts and after 30 seconds goes into a loop of restarting over and over.

 

i can take some roasts but would be nice if some expert could also give me 1-2 tips (if there is anything to try left).. thanks!

Hardware programmer. You are just out of other options. You have to flash the original bios on the bios chip directly with programmer.

Yes, I already ordered one. Should arrive within the next 3 days. Is there anything I can do now?

 

oh I read it wrong.. only option I see..

 

weird part is that the clevo support told me that the bios version was the right one

I have to agree with him there!
That with the programmer you must also consider certain things. But just try it out!

Is on the way.. I only have to find the old working bios version then.

 

FN + B (recovery mode) doesn’t work? Also it has 2 bios chips, isn’t one suppose to be the backup bios for such cases?

It doesn't have two bios chips. It might have a recovery BIOS flashing available though, but I am not sure. Try looking for some BIOS related stuff in the service manual. Perhaps there is some info regarding this.
