Wil give this a try and see how it works out for me. Thanks!
If there is someone with a desire for non-autotune settings, be brave and please report if you get same results as I had

I had a problem booting my Antminer R4 8.0 Th/s, batch 2, autotune-model.
So I went looking in here:
Bitmain.com: Three Ways to Restore Factory Settings (R4/S9/T9)
https://enforum.bitmain.com/bbs/topics/3957
I used the last option in the list, IP Reporter button restore.
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.
This was not my original problem, but I'm happy with it.
My original problem was that the miner jammed somehow in the booting process and didn't even show up in my router ip list.
