Are you sure that you were following the instructions of firmware After 2019 and not the other one?

I know there are two ways to run Braiins, one is by flashing it on the control board and another is by booting from the Sdcard after changing its jumper settings by switching JP4 jumper position, in both cases, you will need to move that jumper, the only difference is that you would keep it changed (to the right side) if you want the miner to boot from the Sdcard.

If you need further help with Braiins you should contact Artemis3, I think he has the most experience in that firmware among us, if things still don't work, try Vnish.

Also, since you are running the latest firmware which is more securely locked than others, it might not be easy at all.

An update even though my account on my netbook was an administrator account you have to force the etcher software to run as administrator before it will flash the SD card.    Windows go figure...

In any case I now have an SD card that has been flashed with the bootable file.  I'm currently at work I will not be anywhere near the machine for another 7 hours.  I will probably play with it tomorrow morning After coffee.

Welp.  That didn't work.  I moved the single jumper as indicated (annoying to get to)  I had to take the fan off the front and slide that aluminum housing forward to get that control board out.  Replaced everything, inserted the flashed sd card and the machine simply says fault, and I get nothing from it.

Tried a few times.   Zero access. Fault light steady.    Removed sd card pulled the cowl again moved jumper back to original position reassembled and it seems to be functioning like normal.   Its possible that the flashed sd card wasn't flashed correctly I have zero knowledge on how to check that.

I am looking in to that software version of updating.

There is a good chance that the Sdcard you using is bad, I am sure almost everyone has experienced such a thing before, some of those Sdcard simply won't work on the S9 flash.

Also, there is a chance that you might be doing something wrong, my advice would be this.

Use the stock recovery files, download from this link https://service.bitmain.com/support/download?product=Flashing%20SD%20card%20with%20image

Make sure you use this version (t9+ -SD Tools.zip), do not under any circumstances use the S9 version which was published a few weeks ago, also to be on the safe side I would use the stock recovery files but download them from elsewhere such as from here https://vnish.ru/en/firmware/antminer-s9.html or ask one of the trusted members here to send it to you, just in case the publish date for the t9 files on Bitmain's website is incorrect, you simply want to avoid anything new form bitmain because that will make things even worse.

Follow this guide to flash the miner: https://support.bitmain.com/hc/en-us/articles/360019493654-S9-series-S9-S9i-S9j-S9-Hydro-Control-Board-Program-Recovery

If that does not work, try a different Sdcard.

That was an annoying chore lol.   Who would have thought I would have to resort to command prompt to force a partition on to an SD card.  Windows was completely refusing to partition the SD card larger then 16MB so no files would fit on it.

The miner has been returned to factory.  With that T9 version. Will attempt a remote upgrade to brains after lunch.

Stuff like that happens all the time.

There are 2 versions of BraiinOS, one is free and the other one has dev fees, the latter comes with more features like auto-tune which you might not need, so I would stick to the free version and start with the lowest frequency and increase it one step at a time, you will need a Watmetter or amp clamp of some type to measure the power consumption, you don't want to push past 1000w to be on the safe side.

ok. so next problem that ive run in to.


when using the cmd and typing in.  bos-plus-toolbox-am1-s9 install 192.168.2.14.....

it goes ok  password.   entered.   installing files  at the end it says  failed.  unsupported miner version Antminer t9+ 

ok guessing the flash to original thats supposed to be the same as the t9.   isnt. 

does this mean i use one of those old flash files from bitmain for the s9 instead?

There is no need to do that.

Anyway, your current problem is related to installing BraiinOS, I suggest you ask this question here, alternatively, use Vnish (AwesomeMiner or Asic.to), those are easy to deal with, you can flash them from the webpage itself but they both have dev fees.

Hi, I see that you have a lot of trouble flashing your S9 ... I also see that you have the 2018 version installed above, which shouldn't be a problem for an update ...

I propose to you, my thread, which consists simply in making an update, then installing my patch, and you will thus have control of the tension and the frequency ... all without SD card ...

let me know if you are interested (update links), this is all completely free and risk free, and it will not block your miner.

again id like to thank all the people that helped me on this.  My s9 test/learning unit is up and running with the Braiins OS  now i have to learn that.

And after some testing and alot more reading yes i Did have to install some s9 firmware from 2017 on top of the return to t9+ before the braiins installation was able to recognize what it was dealing with.

now i have to learn yet more new software and figure out how to get all 3 boards running at some sort of low rate and a much lower fan speed.  theres no way that the person i will be sucking power off of will tolerate that fan at that volume.

[mikeywith]

I am glad you got your miner up and running, now for the fan noise part, you can manually set a fixed speed, usually, anything below 40% is "ok", the stock fans are noisy as hell compared to other fans, there are other methods proposed by thierry4wd and phill for noise reduction ( search the forum you will find them).

In order to reduce the fan speed without toasting your miner, you will need to reduce the voltage and the frequency, I suggest you start with a frequency of 475 and 8.0V, this should (at least according to taserz whom I trust) give you 10th at 750 watts, the miner will run pretty cool and if the room temperature isn't bad, I think you might get away with 30% fan speed.

I adjusted its settings prior to going to bed last night.  Results are 10 and 1/2 TH running on three boards. Fan speed 38% I let it adjust those speeds on its own. 

I was unable to tell the unit to run at 475 and adjust its voltage. It did not seem to matter what I put into those for adjustment, the unit ignored those settings.  But changing its power setting was a different story, limiting it to 800 w it automatically on its own brought the speed down to about 473 and it's running at 7.94 volts.  Again I don't seem to have any control over those settings except for the wattage limitation.  Temperature is hovering between 60 and 80° c.  And the fan will ramp itself up and down to adjust temperature.  Each board was being limited to 241 watts.

But the most important thing of all for what this unit is going to be doing is it's almost down to a large PC fan sound.  It's quite tolerable to be in the room with it.
