Dell Latitude 5520 Bios Password unlock

[SMDFlea]

hi Markus1741 I have read the bios file in situ with pogo sticks and taken off board and read same result every time, is there any thing available that will get me out of this situation, like a generic bios, the machine fires up 1 out of may be 50 -60 so seems to be bios related. Thanks

What model is your programmer and software version

If you have another programmer, such as a CH341A try making another backup with that, to rule out any problems with the T48. The file is definitely corrupt

Now I don't know if this is an alternative but it works.
David Griffith's minipro project for the T48 has been around for a long time
It's just Linux, but I tried it and it worked for me on a Dell 5501 with 8FC8.
Reading and writing at 480Mbps takes significantly longer than with the original software.
I don't know if you're familiar with Ubuntu.
