Please I need help to unlock BIOS update file with expired signature Dell Inspiron 15R SE 7520 bios A14.exe
QCL01A14.zip (3.2 MB)

105

Didn’t know a signature can expire… Or you mean expired digital sertificate?

106

Both, I would like to solve!

107

You have a security certificate from Dell? These are not publically available.

Also, solve what? What’s the issue?
If this is a modding request, I’m not the right person to help. I was only interested if you have difficulties with “A14.exe”, otherwise, why would you mention signature.
