Hi Tazers,
I tried to flash fix-650M firmware ("Antminer-S9-all-201705031838-650M-user-Update2UBI-NF.tar/gz") to my S9 (which has the default auto-freq Nov 2017 firmware), and I got this "Invalid Upgrade version" messages.
The S9 rebooted itself and it still has the default auto-freq version. So the flash failed.
Could you kindly advise what should I do to flash the fix-650M ?
Thank you very much.
have you solved this problem? i have several S9 13.5T (auto-freq Nov 2017) that report 100+C chip temp on this bmminer880, want to try it with fix-650M firmware.
