Thanks for this helpful link.
I've tried both, but nothing helped.
Maybe Anna Luo from the avalon miner support can help me

What I guess is that the program itself is corrupted after you downgraded it to a lower version try to reflash it again with the same firmware or I guess the firmware that you flash is corrupted try to redownload the file and reflash it again.
If it still doesn't work try to revert it back to what it was before or reflash it to the latest version. Maybe the older version have bugs to pie chart so upgrading it to the latest version should fix this issue.
