Solving remote: Writing 'system_b' FAILED (remote: 'No such file or directory')

[XyzarGD]

I followed the instructions and everything worked fine, my bootslot is A so i deleted b, worked fine. then i did .\fastboot flash system system.img and first it told me FAILED (remote: 'Not enough space to resize partition'), i looked up a video on youtube and the guy said you have to delete your actual bootslot. I did that, now it says FAILED (remote: 'No such file or directory'). I also tried the second newest build, it resulted in the same issue.

Did you decompress the image you downloaded? Instead of .img.xz, it should end in .img.

I have the same exact issue.
