Hello brother, thanks for answering.
Right now it's fixed for me.
Changed my 256GB to an old 2TB Toshiba external HDD that I have
Watched your video about: running ps4linux without installing and then applied on my external hdd.
Then it worked first try (without even "resume-boot" command).
Things that I want to add about 256GB SanDisk that didn't work:
1- it did not want to show on my ubuntu virtual machine for some reason (tried a lot of troubleshoots).
2- it was shown on my internal ps4linux so I applied your video tutorial on it about: running ps4linux without installing. (same error as the photo above).
Appreciate your amazing work brother.
Thanks.
