HELP with BRICKED DELL BIOS EDIT

[coatman]

DELL BIOS MOD REQUEST:

Hi, Sorry not sure if is the right forum but here goes...

I bricked my laptop while trying a basic reinstall of Windows 10, my USB device didn't appear in the UEFI Boot Menu so I selected to try the Legacy Boot Option, the USB drive appeared I selected it, it loaded but said it couldn't find a bootable image, I pressed the option to reboot and from then it has been bricked, I think I'm stuck somewhere between POST and the BIOS due to boot guard/secure boot or similiar, it powers up for a while (10 sec) then the fan revs up and it shuts down. I can enter the BIOS recovery by pressing ESC and CTRL while plugging in the AC adapter, it reads a Bootable USB stick but I get nothing onscreen, i think the boot guard is blocking the drivers.

I purchased a CH341A Flash Programmer with SOP8 Test Clip and have extracted the BIOS from both my bricked XPS 9550 and another operational XPS 9550 I have borrowed using Flashrom on a Raspberry Pi, these BIN files are in the same directory as the RW Everything Report below. I thought it would be best to reflash the bricked XPS bios chip with the image extracted from the operational XPS bios chip, but after reading about all the Device Id's etc, I'm not sure how simple that is or if the normal SLIC process would be sufficient.

I'm very well out of my depth in this regard, I have been doing a lot of reading but I'm still not feeling confident with what I have to do exactly, so if someone could help out it would be most appreciated.
