Hello,
It looks like my Antminer S4 is hacked by someone via SSH i think. I can log into the S4 via the webpage. I can see that it is mining but not at the pools i set. Miningrigrentals confirms this, it says there is no connection.
I already tried a factory reset, update firmware via webinterface, firmware on the SD card.
Nothing works,the static IP adres keeps in the S4, and i can't change it. Login via SSH is not possibele because the password is changed.
Need help, who knows what to do?

hi guys,
Bitmains last S4 firmware has a HUGE BUG.(or they do this in their knowledge for sell alot of S5) We cannot change voltage !!!
if you want to do downclock you must to use previus version.
initramfs.bin.SD-20150129.tar this version is Bad for voltage settings...

THIS IS CONFIRMED ON MY ALL S4'S. IF YOU WANT TO DO DOWNCLOCK DONT UPDATE THIS FIRMWARE.!!!
this firmware making fixed voltage 0,725 V. this is BAD FOR WATTAGE ! BUT FPGA CHAIN1 PROBLEM IS GONE
(for me doesnt matter, i fixed chain1 problem myself)
BITMAIN, WHY DID THIS? WE NEED CONFIGURABLE VOLTAGE AND WE PAID A LOT OF MONEY FOR THAT !!!
FIX THAT SHT !!
What was your solution for fixing the chain 1 issue?
I haven't tested lowering the voltage with this firmware yet, but hopefully bitmain will fix it if it is broken. The new firmware works MUCH better than the old one.
Turkish solution : seperate pic12F's J7 (chain1) connected tx signal from main tx signal and give tx signal from neighbor hashboard to j7 connected hashboard's pic12F.
then "islem tamam" (volaaa) all boards are same voltage.That all flew over my head LOL. Could you give more details for the simple folk like me?
yes 61... a bit too high but every customer have different deployment method. Looking at the running up time, at least the high end is stable or managed some how, so it's not crushing the unit.
For some reason my chain#1 on my units are the hottest not chain #4.
because chain1 is connected to J7 and fpga cannnot set your proper voltage value to J7 connected hashboard. chain1 is always working 0750V. i told a lot but no ones listen...
Hi,
i mining in f2pool for 2 weeks.
last night 2 of my S4s shows they find 10 blocks!
is this a glitch or real?
f2pool block page is not update, so i can't figured out it was me or not.

If the "bestshare" size is over 44,455,415,963, then you found at least one block.

Its S4... 
Yeah... probably means the fans are running way too fast causing a hotspot because the air can't circulate properly.

yes 61... a bit too high but every customer have different deployment method. Looking at the running up time, at least the high end is stable or managed some how, so it's not crushing the unit.
The highest is 61 and the lowest is 28. That's a bit weird.

@abracadabra,
Thanks! Sorry for the wait. Wish we could have gotten those to you a bit sooner. Darn weekend? Why do we have a weekend?!?!?
7 days work week baby! - YAY!!!! may be not...
Also, please check the fan speed and physically looking at the fan as well. Some fans seem to dry up the grease and spin slower. (Not many but a few, it seem to be happening)

Just wanted to says thanks to BitmainWarranty and Yoshi. I know sometimes all you hear about are complaints, so I figured I throw in a compliment. I requested replacement fans on Thursday and got them today.
Thanks guys! Much appreciated!

True that.
That said, the temps look funny.

then "islem tamam" (volaaa) all boards are same voltage.yes this firmware is good, but not very good, try this then you will understand simply:
read your freq (eg 200)
read your voltage (eg 0720)
read your wattage (eg 1350Watt) with meter
than change only voltage settings to "0650", reboot, now you are 200mhz 0650 V,
normally this config dont work properly but you will see almost same
you will say, this hashrate is impossible with this voltage only 0,650V (this works 175 mhz-1600Ghs)
than read wattmeter you will see 1350w again
VOLTAGE NOT SETTED.
@sloopy,
If you could, please send your shipping info and Order ID and a telephone number via that ticket. If you have already done so, please one more time with "sloopy" in it
If you have a spare PSU to power the unit, please DO so, as that will not void the warranty.
Thanks

I called BITMAIN support and spoke with a new guy. He sent me to the BITMAIN Zendesk to fill out a ticket.
Now I wait
I use the 2000 watt PSU as my replacements as well.
I try to be fair to BITMAIN and use all of their equipment on the units with warranty left, but you are probably right. Once I test it I should leave it until it is sold.

If you're editing cgminer.conf, you may find some of these other cgminer arguments interesting:
A few of those (--bitmain-homemode, --bitmain-fan, --bitmain-temp) could make nice options for cgminer.conf for people who don't want their fans to burn out. I'm also curious if --bitmain-auto works.
Code:
--bitmain-dev Set bitmain device (default: usb mode, other windows: COM1 or linux: /dev/bitmain-asic)
--bitmain-hwerror Set bitmain device detect hardware error
--bitmain-checkall Set bitmain check all
--bitmain-checkn2diff Set bitmain check not 2 pow diff
--bitmain-nobeeper Set bitmain beeper no ringing
--bitmain-notempoverctrl Set bitmain not stop runing when temprerature is over 80 degree Celsius
--bitmain-auto Adjust bitmain overclock frequency dynamically for best hashrate
--bitmain-homemode Set bitmain miner to home mode
--bitmain-cutoff Set bitmain overheat cut off temperature (default: 60)
--bitmain-fan Set fanspeed percentage for bitmain, single value or range (default: 20-100)
--bitmain-freq Set frequency
--bitmain-voltage Set voltage
--bitmain-options Set bitmain options baud:miners:asic:timeout:freq
--bitmain-temp Set bitmain target temperature (default: 50)
--bitmain-hwerror Set bitmain device detect hardware error
--bitmain-checkall Set bitmain check all
--bitmain-checkn2diff Set bitmain check not 2 pow diff
--bitmain-nobeeper Set bitmain beeper no ringing
--bitmain-notempoverctrl Set bitmain not stop runing when temprerature is over 80 degree Celsius
--bitmain-auto Adjust bitmain overclock frequency dynamically for best hashrate
--bitmain-homemode Set bitmain miner to home mode
--bitmain-cutoff
--bitmain-fan
--bitmain-freq
--bitmain-voltage
--bitmain-options
--bitmain-temp

--bitmain-homemode works
--bitmain-auto doesn't work
--bitmain-fan doesn't work
I'd say you've got some really bad luck, combined with poor quality control by the PSU manufacturer. I've resigned to running my S4s with different power supplies, and keeping the originals for when I resell the units used.
Here's a picture of 4 of them running off of Delta 2000w server PSUs, happy and stable as can be:
