Hello!

So I wanted to make a bootable kali usb drive so i used the last image from the kali website and used etcher to make one.
I used it to boot on kali once to see if everything was working and it was. Then I wanted to make a LUKS encrypted persistence on my usb drive, so I followed all the step on the kali's website.
After that I tried to boot again but using the encrypted persistence: it detect my partition sdb3, i type my passphrase in qwerty despite i'm used to azerty. And then i'm stuck on the same frame with no input but still the message "please enter your passphrase..." i waited some times(almost 40minutes) and nothing happened. I tried to boot again on my own linux distro to wipe all the drive and try again without using etcher this time to try again. But for some reason the usb drive is now in read only and i can't do anything with it. (Read-only file system) Already tried severals things but can't find how to solve this problems without burning it with an incinerator.
