Hi i recently bricked my ph315-52-78VL bios. I updated windows 10 and just nonchalantly ticked the optional update for my bios.. computer restarted and fans ran on high for 30 minutes. Bricked bios I have the chip attached to a Ch341a programmer after doing the battery power reset to no avail. I am in need of a working bios file to program the chip. Also it has always bugged me not being able to change ram voltages and timings is there a way to unlock the bios and hit two birds with one stone? Thank you in advance! ( @Sweet Kitten is it fine to post here?)

First, we will try to fix your bios. You say you have CH341A, upload chip data so I can download it.

Sometimes programmer cannot write properly if the chip is still soldered to the motherboard. How does the chip attached to your programmer?

I have desoldered it. I really dont like to use the clips and have it in a sop8 socket directly attached to the ch341a.

I am using AsProgrammer version 1.405 on windows 10 if that could be causing issues? Maybe a driver problem?

Hm. It becomes more complicated. I just took the BIOS dump from the working device, replaced the identification data in it with yours, and gave it. Maybe @Pythonic wants to prove himself?
