Yes I did. Doing again
how to get back my sd to normal for windoS afterward ? I want to try my 256gb. Took so much time on my 400 maybe something is wrong. How long is that supposed to take ?(gapps)
Hmm yeah that would be worth a try, card-speed plays a big role here and if the flashing took you already 20 minutes chances are you couldn't have used Android satisfactory with that card anyway. Flashing took around 5 minutes with my 32gb card and Android is still somewhat choppy on it.
Oh and yeah I had big trouble getting my SD back to Windows-readability too with Windows itself. I ended up using macOS on my Macbook which managed to get it back to a normal state in a breeze. I assume Linux would make it just as easy, Windows is very limited with these operations.
