Bitmain.com: Three Ways to Restore Factory Settings (R4/S9/T9)
https://enforum.bitmain.com/bbs/topics/3957I used the last option in the list, IP Reporter button restore.
Usage: Please power off the miner, then hold down the IP Reporter and don’t release it. At the same time, please power on the miner.
Releasing the IP Reporter after 5 seconds, the machine will automatically restore factory settings.
My miner restored with firmware Aug. 9 2016 and autotune settings were gone.
I am now suddenly able to control frequency and custom fan settings.
