[attachment=23184]Hi
I have a HP OMEN 15-dc0850nd that is stuck on black screen when turned on power button light up fan ruining and caps lock blinks 5 times(slow)+3 times(fast) according to HP website "This condition indicates the embedded controller cannot reach the BIOS within the established time limit."
I'm going to flash the bios using an CH341A(waiting for it to arrive) and I have some questions
There is two chip on the motherboard
GigaDevice - 25B127DSIG I think this one has the bios since its a 16M size
GigaDevice - 25Q80CSIG This one is 8M in size
First question about the bios I downloaded the file from HP its sp127587.exe which create C:\SWSetup\sp127587\BIOS_Update.EXE
Running the exe file give option to extract to usb or a directory both result in 2 files 084DA.sig(1 KB) and 084DA.bin(16,384 KB)
Do i need to modify the bin file before flashing or just backup the one from the chip and flash?
Second question is about the chip it seem most tools don't have this chip and clicking on detect will suggest 2 or 3 different chip
From the research I did some people had success using W25Q128BV or GD25Q128C is it fine selecting a different chip suggested by the software?
Last question what's the best tool/version to use AsProgrammer, CH341a Programmer..?
Thanks
PS: The bios on the laptop is the same attached
