Did wget succeed?

Try doing wget line again and make sure it downloads the file.

Check where you are and what files you have:

pwd
ls -al

When I tried to follow the directions below to update my S4, when I enter "chmod +x cgminer" I get "chmod: cgminer: No such file or directory.
What do I need to do to correct this so I can finish with the update?
Thanks in advance for all the help!

And test it properly to make sure that it works with every pool.....

Great!  Now that we can get them here in one piece, let's get the firmware updated so it can work without having to apply fixes to it every time it has to reboot.

We have drawn on the delivery experiences of AntMiner S2, design the S4 with less hash blades and adjust the space structure in each box to bring a light and portable model, enhancing the stability of the machine. What’s more, we improve the packaging type and materials to minimize the damage during transportation. And now S4’s package is successfully tested by the methods meeting the regulations of ISTA 1A & ISTA 3A. The entire outer packaging is good enough and S4 is still working normally after critical testing. ISTA® test pass plays an important role in ensuring the safety and stability of the AntMiner S4 in delivery process. 

In addition, the power supply issue of AntMiner S4 has been solved properly. The replacement PSUs we announced early are almost processed and we will be focusing on issuing the compensation to the effected customers this week.

We really appreciate every customer’s great support on BITMAIN. We do always have the time listening and humbly accepting your suggestion on the miners and other products of BITMAIN. And will spare no effort to design the miner that benefits all the bitcoin players!

Sounds about right, the latest firmware definitely had a small hash rate bump in it.

Interestingly, when using the old S4 firmware WITH CK's fix and queue 0 i was still getting hash rates in about 1920-1930 on my P2Pool node.

When I updated the S4 firmware (20141016), placed the queue 0 setting in and used CK's fixed cgminer, I'm now in the 1970-1990 range with my P2Pool node.

Just thought I'll let you all know

agreed

apparently it was just a coincidence that the first few times I ran ck's firmware that it powered off after 5 hours or so; it was likely due to weather that may have caused the electricity to go out. I have now been running t successfully for 24 hrs straight without issues. I also see 0 as my 5s avg but it's mo big deal bc it's obvious what your actual, real average is in the next column, certainly not a huge issue at the moment...

I pointed out in an earlier post that with CK's fix, the 5s average shows zero.  I propose we leave this as is until Bitmain fixes their firmware so that it's an easy tell that the machine has rebooted and is not using CK's fix.

Just my thoughts.

Running perfect here using CK's tweaked firmware. My 2 s4's have been going 24x7 for the past 2 weeks with zero issues.

Any fault lights lit by the plug on the psu? Using the right power cord that has at least 16ga wire in it? 14ga would be ideal. Per my UPS the s4 pulls 12.6A with 120v feed. A 'normal' cord is 18ga and definitely not a good idea as they are only rated to 8 amps and aside from getting rather warm will also produce a large voltage drop between the wall and the psu...

Is anyone else experiencing an issue using ck's s4 firmware where the S4 powers off after approximately 5 hours? I'm not even sure that the issue is a result of ck's firmware, but as i mentioned earlier in this thread I mine exclusively in the eligius pool, so if I want to achieve a hashrate > or = 2 th/s, it is necessary for me to use his firmware which seems to work excellently with Vardiff pools that don't let you set minimum worker difficulty...

Edit: I guess a better question might be- has anyone had a similar issue with their S4 powering off after approximately 4.5-5 hours (regardless of firmware)? If you have, what firmware are you using?
Is anyone using ck's s4 firmware for their S4 and has been able to run 24/7 without any issues?

Not so cheap, but there are some listed on Amazon.com...  (Voltage Regulator)

Don't the S3's draw 355W? You should be able to fit 3 on one of these little guys?

Did anyone try to change the fans to reduce their noise? I have some Arctic F12 PWM Fans but unfortunately heir plug does not fit to the controller board. Are there any recommended fans?

That's a nice little unit at a nice price, but I'd need quite a few of them!  1200 watts is enough for two (but not quote 3) Antminer S-3's, but not quite enough for an S4...

NOTE TO THE PUBLIC, ESPECIALLY THOSE CONSIDERING DOING BUSINESS WITH BITMAIN: Please disregard this post, at least until BITMAIN sees it and realizes how foolish they are for not just compensating me, knowing full well I don't have any problem with posting the TRUTH! The following post essentially be ignored, 80% of it was copy/pasted straight from a member of the BITMAIN team in order for me to "turn this into a positive experience" (which, as a customer, is not my responsibility, but when you are dealing with BITMAIN, you are pretty much forced to do whatever they say if you actually want to have a chance of being made whole for whatever reason (and christ, there are dozens) that they owe you compensation. Of all of the names who I listed in this post, I never even was in CONTACT with ANY of them except for 2 or 3, maximum. Like I said, this was a copy/paste job by me from a BITMAIN employee who really did help me out, but apparently has since abandoned me, and the following was what he wanted me to say. I even made edits at his request. This is the end of my disclaimer.
Anything below this line is the "original" post I made.


BITMAIN- Thank you so much! I owe you and the entire BITMAIN staff an apology for being so quick to hop on these forums and say that you guys were screwing me over. Thanks to BitmainWarranty, I was able to get in touch with the Bitmain North American team who arranged for me to send my unit to Denver and I received a replacement unit this morning. So far, it is hashing wonderfully! My faith has been restored in BITMAIN and I once again can say without a doubt that they are the BEST ASIC manufacturers on the globe!!

I am providing this update because I want everyone to know that the BITMAIN team are dedicated to making sure that their customers are satisfied.


 If I have learned anything from this, If I or ANYONE ever has any issues with a BITMAIN unit and lives in North America (or anywhere on the globe, for that matter, as I understand that the North American team can offer parts replacement with a fee, and the same applied to the expired warranty item, if the parts replacement is needed), call 1-844-248-6246 (844-BITMAIN) !!! Your problem will be solved much faster than if you were to contact the regular BITMAIN support email address. They will process everything for you very quickly, and obviously will have faster shipping times, as they have a location in Denver where you can send your unit (even if you aren't sure what is broken). Their address is 3700 Quebec St #100239, Denver, Colorado 80216. As long as there is a printed original purchase order page with full information, a brief letter describing what is wrong with it and the original unit will be diagnosed and if its defective, the replacement/refurbished/repaired unit will be send back to the customers in just a few days!!!

I want to personally thank the tech guys in Denver for taking care of the the logistical aspects of my SPEEDY RMA.
Thank you James, Billy, Andrea, Faty, Z, Ken, and all others who work so hard to keep BITMAIN customers satisfied!!! I  also would like to thank Tim in China, manager of international sales, who was also of great assistance. And I would not be able to forgive myself if I did not mention Yoshi.

All BITMAIN North American customers need to be aware of the North American staff! I know I am beginning to sound redundant, but things would have gone SO MUCH smoother if I had contacted them from the get-go. I just want anyone who might have an issue in the future to be aware of these wonderful resources.

Right now, I am hashing over 2 TH/s with my Antminer S4, so I can indeed say that this miner does live up to its advertised hash rate. And I haven't even played with the frequency yet!!! Do not hesitate to buy an S4!

Despite the frustration that I experienced, this has been a wonderful learning experience and I look forward to doing more business with BITMAIN in the future, especially now that I know there is a team in Colorado just waiting to help anyone who has issues. I hope that I have not harmed the reputation of BITMAIN as a result of anything I said in anger. I am actually ashamed of myself for getting so rude with the staff, particularly now that they have shown me that they are willing to go so far to assist customers, but they are so professional that they took care of me despite the fact that my responses were sometimes pretty nasty. I just can't say how pleased I am, so I am going to end it here and try to find the firmware that will let me mine on eligius, but right now, BTCGuild is just fine!!! :-)

THANK YOU for the update … All I ever wanted was to know what to expect …. Setting out a time line like this and communication is the KEY to doing good business .

See https://bitcointalksearch.org/topic/m.9207574. I believe you need to contact your reseller [and get your reseller to email Bitmain as per the link].

If I bought a "S4 batch 2 with a defective PSU" from a reseller and you guys already shipped me the PSU replacement, what information do you need for me to get my compensation?
