hi dear thanks for your information but
i test your first post auto updated file but when i upload this file in z9 mini has error for upload
whats the problem
What does the error say? What web browser?
Also you don't unpack the file you upload the package as it was downloaded. The file name should look like this:
Antminer-Z9-Mini-NAND-500M-201808311812-unlocked-Refresh.tar.gz
if it looks like anything else the your web browser may be unpacking it to the sub files. If this is the case disable un-compress files option in your browser. I use chrome and IE11
If you unpack the first gz file and try to upload the other it will give you an error.
I just downloaded it and was able to upload it to a batch 4 machine just fine.
