        you can revive it back using known good bios yet there is some problem such as slow perforamnce camera not working keyboard backlight not working.. so unlocking the orig file is the best move.. and next time make atleast 3backup(click read and save not copy paste) before erasing the chip

              Rules: Always read two times and compare with hxd to exclude other problems and time. When the two files are identical, only then go to the next step!

                                        Dell Latitude 5400 Chromebook UEFI bios
                                        by jhanra
                                        Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                                        so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                                        in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...
