I made a mistake by not taking a copy. Please help. But I uploaded a file to BIOS, but only test colors appear on the screen and the laptop shuts down. Please help. I will be grateful. Thank you

Thanks mate, its working fine with editable service tag. I have 4 or 5 more of these same board
and have been trying to copy the changes made to another bios file I and am about to test the 2nd one.
not holding out much hope the files was not a perfect match some data was a different place
and there was one mod I could not find in the second file. I may be back lol.

Thanks again mate.

Edit, the file you done never worked in the second board.

I put this file in my bios but it just shows the DELL service logo for a few seconds and then the machine shuts down and nothing else shows up after that

Xin chào lần nữa, tôi hy vọng ai đó có thể mở khóa 3 cái khác cho tôi.
Tôi đã tự mở khóa được 2 cái từ mẫu trong lần mở khóa trước nhưng 3 cái này không chỉ khác một chút.
một trong những lần thử của tôi đã xuất hiện ở chế độ chỉnh sửa nhưng vẫn được xem và 2 màn hình trống khác.

Thẻ dịch vụ thứ 4, 3BDPBS3
Thẻ dịch vụ thứ 5, 96DJKL3
Thẻ dịch vụ thứ 6, 1JGCHS3

Cảm ơn, hy vọng ai đó có thể giúp tôi.
