Obviously none of this matters if you can login and change settings.
I thought I read you were trying to reset the settings to defaults.
The 10-24-14 firmware had a bug where the reset button wouldn't work.

You may already know, but when you reset it there is an odd process, odd to me anyway. I am used to resets being performed while it is powered off, but of course I am speaking relative to moving a BIOS jumper on PC motherboards.
For one you have to do it at the right point during boot, or right as boot completes, and you have to hold that bugger down a good long while, which is a real pain when it is offset in the hole. I downloaded a bunch of stuff from the zendesk support site. Im pretty sure one of them was an S3 reset doc.
Yeah, it says 2 minutes after boot in their reset prochedure:
https://bitmain.zendesk.com/hc/en-us/articles/202648429-Reset-Prochedure
Their instructions leave out how long to hold the button down. It has been a while since I did it, but I remember reading to hold it down until it beeps. Like I said it was a long wait but finally it beeped, and reset.
Also, if upgrading I never keep my settings. That was a bomb scenario with one or more versions of the S3 firmware. IF you selected to retain your settings it would come back up and you would get a messed up screen when you went to the login page for the miner.


If you are running 10-24 fw or close to it, you won't get it to reset, at least no one else could that I ever read about. Many of us opted to send the boards in, and bitmain used the debug port on the control board. It is a USB to serial gizmo you can pick up all over the place, amazon has a ton of different ones. Then you have to use a program which will talk serially, correctly, there is a whole thread dedicated to the Jtag port aka debug port.
I wanted to do that project then, but was in so deep setting up my farm I couldn't take another project at that point.
There is a fantastic thread about this and the last post of instructions lays the entire process out perfectly.



I run 10-24 firmware on all of my S3s, but have been playing with Kano's version and plan to move a couple of my best S3+ performers to it. I am selling the rest so I will update to Bitmain stock so they have reset button functionality and it is factory firmware. I guess depending on the situation I may ask the person purchasing if they want Kano's version installed to keep them from reinventing the wheel if they aren't familiar with how to do so.

If you have an opportunity to use Sidehack's services for work, I would do so. I understand if shipping isn't cost effective, but you can't get much selling an S3 today either. Probably $75 bucks max. So if you can make btc with it, evaluate everything. Even if you can't mine $75.00 you may have a way to get close, and if I can keep the hardware and it only costs me a few bucks, meaning i'm not going to make much more selling it, then yeah I am going to sit on it, because of just in cases.

Just in case I can use a Gekko Science retro kit with it.
Just in case price soars and I can put everything back to work full steam ahead
Just in case I hit the lotto and I can put everything back to work immediately full steam ahead while I build my real mine Smiley

Now... I did try the 2-minute thing several times. Flipped the switch on, timed 2 minutes, then held down the button, waited and reset. Nothing beeped... I wonder if I hold it down for longer? Worth a shot...

@sidehack, if I get such a device, is this a really difficult task? Is it as simple as feeding it a firmware and it'll update as if through the OS? Any tutorials on how to do this? What I had heard was, that people re-installed the firmware on the SD card, which I'm assuming are in the large units in the beaglebone, or whatever they used. That seems simple enough. Is this much more difficult than that? My expertise in these things is admittedly non-existent at the moment. Thanks for your continued help!

Sloopy mentioned in this thread a week ago that there's a whole thread on how to do it. Might could try the search function.
