Dell XPS 15 7590 BIOS unlock

[Markus1741]

Hi markus, the bios gives issue on reboots, I flashed the bios again, turned off auto recovery, used it on windows for couple of hours. it rebooted once perfectly fine, but on second reboot , the bios crashed and showed 3 orange 6 white led blinking. I read the bios again and am attaching it here.

Hello,
I had the same problem once with a Dell 5590.
I also recreated the BIOS with 3 and 6 flashing and then everything worked normally.
Days later the same 3 and 6 flashes again, I then discovered that the Gigadivece IC itself was defective.
Then I used a Winbond and everything was fine.
I would use a new chip or another chip for you.

Hi Markus , so its been 24 hours i have changed the chip and flashed the bios that you cleaned for me. There seems to be zero issues. I have disabled UEFI updates as a precaution. Thank you so much for all the help you offered.

Also for anyone else who's having bios auto-recovery issues, you should try replacing the bios chip.

I will keep using the laptop and if there are any issues, i ll post an update here.

Thank you so so much, Markus. You are awesome.
