Here's your Unlocked BIOS, hope it works fine.

Hello. I tried your file but it flashes 3 yellow 6 white.

A small update regarding my situation.
I had found in topic need bios dump dell latitude 5420 cpu 11th this posting.
Someone else mentioned that the file "try 2nd outimage" worked for that person, so I have used it also.

And I can confirm, the file worked like a charme. Kudo's to qayyum786

[diamon]

If the file is still corrupt, is there a solution ?

I have read the bios chip again with 6Mhz.

The first time was wanted to read the chip, I pressed the Auto button. I noticed it was starting to erasing, I removed the USB cable

I had used the https://github.com/chromebreakerdev/DellBIOSTools script, but it gives me an error, that the Intel signature not found.
Think i perhaps know why, wanted to read the bios file with my EZP2019 programmer and pushed the wrong button 😣 (AUTO > auto recognize the chip brand and size).

Corrupt backup, slow the programmer speed to 6Mhz and try again.

post merged..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..
