DELL Inspiron 5551 bios

[Bassem]

I have DELL Inspiron 5551 problems with bios,
1- Bios won't save changes from dos or by downgrade or update exe bios file
2- can't use any USB bootable now
3- F12 becomes uefi with legacy oprom security off, and can't chance from it and can't read any device as before, also no efi boot always not found.

Operation system was Ubuntu before I find problem to change it by USB as always , then I used DVD writer and tried, Ubuntu 14.04 , 16.4, 17.04, 17.10 , removed all and installed Fedora 27 , windows Microsoft 8.1 pro with all drivers from dell site with bios file, windows 10
deleted all my hard disk and no any change
Also removed CMOS , Hard disk and battery just ac power , and ac power with battery
the same problem can't change boot options from f2 or f12

I tried to extract files from 5451_A03.exe but no bin , rom or hex files, and I tried to use commands port to make files but no thing happen and I can't find any bin or rom

It's the last way to try it as I think, but if any one can help to fix this problem so thank you
and I need help to extract bin , rom and hex files to try to flash Bios from dos
