One of my R4's that stopped hashing on one board has stopped hashing completely after trying to restore the original firmware. The hardware version listed under system overview says " Socket connect failed: Connection refused".
I have tried powering off several times, reboots, updating firmware, etc. No more hashing. There has to be an easy fix to this without sending to Hong Kong or letting sit in Denver for weeks on end. Any thoughts?
EDIT: unplugged the original board that did not hash and fired back up, the one remaining board is hashing again at 4th/s!
Exactly same fault here - I think we discovered common issue. Same thing happened to me And is it also always the top board (chain 8 on GUI) that fails? One of my b6's lost it 25hrs after getting it. One of these days got to send it off to CO for paid repair...

Well, this is an interesting find and I thought I'll share it with you. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) 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/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. ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) 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.

Anybody have any idea of what is up with this temp? Everything seems to be working fine, but that's just way out of range. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fwww.mrdave.com%2FUntitled1.jpg&t=665&c=mrMUDRaMnKcRzw) Thanks, Dave

Well my faulty R4 is now fixed and on the way back to my place. Fedex has it in Cologne (Germany) at the moment. No details about what was repaired though.
At least they fixed your R4. They sent back a broken R4 that would not hash. I resent it back for repair and now they said they can't replace it because they don't have any more R4 units. They want me to pay some BTC to get as a replacement a T9. It's faster but also louder. Terrible customer service.

Ya they won't budge. My only options are to have them send back a busted R4 or pay up and get a T9. I asked them to provide the cost and also to send me a unit that has been fully tested 100% good. I don't want to pay and then have them send a busted up T9.

It's an 11th/s T9 that they forced me to pay extra for, on top of the cost of shipping the whole R4 unit back instead of just the faulty board. They received the unit back on the 15th and I just received the extortion request today.

It's Bitmain. I opened a repair rocket through their website. They told me Denver was only for out of warranty repair.

I did this on my Batch 6 R4 with a bad board, hoping it would solve the problem. Alas, it did not. It did dump the auto tune firmware and is still hashing the same on the one board, but now I have manual control of the fan speed and frequency setting! Thanks for posting this Hagss!

No problem ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) . You have now the original non-autotune firmware, but you could have one faulty board because you are able to get only one board hashing.

You have now the original non-autotune firmware, but you could have one faulty board because you are able to get only one board hashing. Those batch 6's were super flakey. The board was dead an hour after I started it up. Never could get it to come back. I need to send it in for repair, just didn't want to lose the hash. And it was keeping my office warm. Since I'm in the US, I'll probably shoot it off to Bitmain Warranty in Colorado, now that the temps are starting to rise.

Another R4 acting up. The symptoms are that one board does not hash although all ASICs show 0. The difficulty autoset by my pool (slush) shows about half of a fully functional R4 and the power drawn by the bad board is only about 90 watts with temps in the 90s.
Tried hard and soft reboots and will run ok for about an hour (assigned difficulty goes from about 3k to 6k) and then acts up again and goes back down to 3k. Has anyone ever seen this problem and have any recommendations?

Repair finished, R4B4 is being sent back to Hoth... Fingers crossed all is good!
Well that didn't take long... R4 got back to the Hoth mine and after a few weeks has dropped a board (again) and is running at 1/2 speed. Lame. ![Angry](https://bitcointalk.org/Smileys/default/angry.gif)

Lame. ![Angry](https://bitcointalk.org/Smileys/default/angry.gif) I'll bet it is the top board that's out, right? My gimpy batch-6 I got had a board (top one) crap out after just 24hrs. Since I'll (eventually) have it fixed in CO just been happy with it running @4.7TH and only pulling 430w. Getting warm here so moved my R4 batch-4 from office to the break room. For a while it dinna wanna fire up the top board. Finally after it being warmed by the lower board, several hard boots later it is back up full 8.7TH. Had me scared there for a while... So far in both cases with the dead/nearly dead top board main diagnostic is that the lil' red LED that indicates Vcore supply is live is either just barely lit or not lit at all.

Had one R4 repaired in CO and they did a quick and good job. But, back then I was told to send the whole unit in since it had to be balanced. Now for this second R4 CO said I may be able to just send in the board that's acting up.
Has anyone just sent in an R4 board with success?
Removing S5, S7 boards a piece of cake but I never removed an R4 board. Is there a procedure somewhere showing how to remove R4 boards?

Looks to be pretty obvious: Power OFF of course.
Unplug the PCIe connectors to bad board. It's a PIA to squeeze the tabs on the connectors - needle-nose pliers is a great help.
Unplug data cable from board by squeezing the tab on the cable while rocking the connector back and forth to remove it. Look at front of miner and take out the screws holding the board supports.
Remove board.[

I'll just let it run at 1/2 speed for now. Just had the POS shipped back and forth to the Empire's apparently useless repair facility. Such suckitude it boggles the mind!
