@Sweet_Kitten not yeat, I think the set vars didn't work...

Yes, but I’m sure that I didn’t make a mistake. 0x17 and 0x6D1 are set to 0. Did you reboot the system after setting variables?

Yes, same way that always i did: Run 1 Set Vars and reboot. Run 2 flash and gave me this error…

I generated again the files, take a look if there is something wrong:

I was trying to undervolt the system using unlocked bios since i recently repasted my helios 300
But now it is not booting. It boots but no display and after a min reboots.
I think i set the undervolt too high
Pressing power button for 15sec also does not reset it.
I do not have any experience with flashing chips
Also i do have a cloud backup of the unlocked and locked bios(i think) but dont know how to start
Any help is apperciated

It’s a straightforward process. You need 16 MByte file on your computer and an SPI prog. Then you connect SPI prog with chip and write its memory with the file.

Can you provide the location of the bios chip?
Is it same for all ph315-52 system?

It’s same.

I can’t provide the location since I don’t have a motherboard of ph315-52.
