Today I finally made it work.
I am not sure what was the problem. I tend to agree with Golom about sys.txt but I am not sure.
I copied the original folder.
Then added my content, Frontzosd ux, data.zip
Deleted the _sys.zip ux
Made a mix of original sys.tx and frontzosd sys.txt
@Golom
If you want I can send you my folder
EDIT:
Before, I had use_external_files_dir=0 with comment, now not, so it could be that as Frontzosd said
