It's not working. Error "can't disable wrtite protection"/ Any ideas?

Have You flashed from Pure Dos using an USB Stick ?
Error 28 is bypassable by prr.exe and It say Press ENTER key to continue
Then if all is gone well write PASSED !
If You got Error 28 again then Eeprom is Write Protected and You need
an HW SPI Programmer to rewrite Bios Mod !

tried flash from freedos with using rufus/
Error 280: Failed to disable write protection for the BIOS space/

even if i run prr.exe and flash.bat after it gives me an error.
prr2.exe is same for me with awesome text: can't disable write protection
p.s. may be you will need bios from dell website:http://rghost.ru/8JSN6LZqR

rly? it's very sad. I will face this error no matter of bios version, right?

may be older version of bios can be modded???

You have to try to Downgrade if You can and then redo the result file to see
Eeprom Status !
Problem is not to modify but to rewrite Bios Mod as I have done the mod but
your Eeprom is Write Protect !
