Microsoft Surface laptop 4 UEFI password

[volinakis]

I tried again

compare readings, when you have 2 identical it means you have a good backup. The size is due to chipset, if programmer detected as being 256Mb will always generate a 33.554.432 bytes file. If you use HxD see tab "Analyse" and you have there "Compare"

Thank you! I'm using a WSON8 chip probe pin adaptor. I did 3 readings and the file come always with the same size.

Can be the issue with the adaptor?

First of all, I'm new to this, so please forgive any mistakes I may make.

I have a Surface Laptop 4 that's blocked with DFCI.

darn it. unfortunately, neither of those worked. computer still has the exact same behaviour. i guess a bricked Surface machine is unfixable. thanks anyway, hoaca388. i will keep investigating the issue though. would love to see this computer working some day

[hoaca388]

Could anyone be able to provide me with a working bios? Windows logo for 10 seconds. Can't get past that. Is the laptop bricked? Anyone can help?

Thank you brother

[hoaca388]

Can someone please remove the admin password completely and allow full access to bios? I just need it once then I can hex edit for any others I get. I would be very grateful thank you.
