Have problem with Dell 1546 BIOS update...

[diretouch]

The idea is removing password.

With one way of official dell site it says "the version is same"

Second official way - please put battery

With Rom downloaded from internet and manual update with program it says "corrupted ROM"

With file which i get from windows temp folder you will see the video... -> https://drive.google.com/open?id=1hnZS6W...1uEbfP3LZj
