New here, first post.
Was following bad guide from AI, now have zero signed secure boot keys, or at least a video OPROM issue so no POST. Laptop keyboard lights, as well as power indicator and brief flashing of drive light when there is a drive in. Should have researched better. See the UEFI info on the arch wiki, specifically the warning at the beginning of section 3.1 where it warns about this
: https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot Feeling pretty stupid lol.
Have a boardview file, think I have identified the chip, unclippable with ch341a (not soic8, i think it’s WSON 8). No jumper pads, no bios battery, have tried leaving battery unplugged from board overnight, holding power button for 40 seconds, etc. If there are somehow bios flashback keyboard shortcuts, I have not found them, nor do I know if they would make any difference because as far as I know bios updates skip platform keys I do not have a micro-soldering station.
I think I can get a shop to do it, but I want to make sure I have identified the correct chip and that I have a file that can fix this issue so that they can do it quickly and easily. Need secure boot off/keys cleared, hence possible nvram clear. Other option is a new board ($600-$1200) or buying a new laptop all of which I would like to avoid.
I am also aware that there are probes as an alternative to the soic8 clip, but i am a little wary of that option, please advise on what it would entail and if it as good idea if I were to go the route of purchasing something like this: https://ebay.us/m/n9R1ME
If I can get it done myself, I would much prefer.
If not, what is a fair price to have a shop attempt?
Attached is a picture of what I think is the bios flash. Can’t upload BV file on account of being new but if anyone wants it I am happy to send it some other way. Can also provide the stock bios for this laptop, but I have no way to dump the chip so I can’t provide the specific one on mine.
