Got all password methods?

The question sounds silly, but since there's no longer a bootloader key for Huawei phones, I wanted to create it myself…

The code has 16 digits and only capital letters and numbers.

Is there a tool that generates all possible passwords for such things

Hi

Yes, there are such tools, one of these tools is https://github.com/...h/releases, for example. Your command would then look like this:

crunch 16 16 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ -o list.txt

But that's about 256 petabytes because of 7,958,661,109,946,400,884,391,936 possible passwords that you can't possibly save.
