From various sources i have confirmed that if you update your firmware from Bitmain to any version from 2019, you will lose SSH access. This is the same thing they tried with the S15. We have this confirmed from one of the users. These are clearly evil intensions as they are taking away functionality from the user
they added the signing as on S15, which itself is good if it wouldn't lock people out Hopefully someone will find ways to overcome this, but its clear Bitmain is becoming very hostile to their customers. Beware to not upgrade any Antminer's firmware beyond 2018.
Known methods to overcome this: Remotely via software (closed source): Physically using: |

I'm not sure why you say 'hostile'
Truck loads of people bought T1s that locked you out of both ssh and even direct API access.
The key wasn't released until a LONG time after the T1 existed.
I think you'll find that not too many people care and those that do just want to run hack firmware that is, basically, a waste of time, and bad for the miner and owner.
The only valid reason IMO for wanting access is to fix the API access, but you can get around that also by changing the software to use what is available.
If your miner needs rebooting via the API every few hours, then there's something wrong with the miner.

braiins software is pretty good. once it is installed.
But I have 22-25 s9's and only 2 are using braiins. I just did not bother switching out the other s9's>
I use bitmain's 9.5 th setting and their 13.5 th setting depends if s9 lets me use the 13.5 I have a few that like to run on the 9.5th setting.
As for braiins I do 10.05 th and 815 watts the 2 machines run pretty good on that.
I won't do the 2019 firmware since it locks the s9's down and I don't see what is better Ie does the 2019
do 10 th and 750 watts
does it do 13th and 1100 watts
If it did I would use the 2019 firmware.
Meaning if I lock my gear down I want to gain something for it.

It has 2 settings, as far as I know, from people who commented about it.
One for AB and another for lower frequency.
Not sure if you can use the lower freq without the AB setting (though wouldn't make any sense to do that), but both together end up with better results in the J/H arena at a lower hash rate.
i.e. anyone considering throwing them away, may still get use out of them with both settings on.

SSH is also very handy for issuing "poweroff". Since S9s have no indicator function, powering off a miner via SSH allows you to locate it, or a batch of "its", simply by looking for the S9s that do not have a blinking green light. |

When you have a networked machine with a full-OS controller, you get access. There is no good reason to lock someone out of his own hardware.
It's bad enough that they had full voltage control as far back as the second-version S7 without ever making it open. And building ASICBoost into the S9 from the start then waiting two years to make it open. And then speed-locked autotune firmwares, and the perpetual violation of open-source licensing on everything they've ever shipped out. And let's not get started on selling dust-filled machines as new, allegations of charging for old hardware while mining on new to steal further profits from cloud-mining contracts, and the various BitCH fork and pump and trade-war fiascos. When you already demonstrably can't trust a manufacturer, giving them a pass while working to remove transparency and user control even further is unacceptable.
Maybe it won't affect most folks directly. But the precedent should still cheese us off.

Furthermore this is removing features originally present when bought. Was this even written in the upgrade notes? No, it wasn't. This is disrespectful to their customer base to say the least.  "Enhance security" = You won't be allowed SSH access into your Asic miner anymore. If they respected their customers, it should have been optional, with an option exposed in the web ui to disable it. |

Yep they've been doing this for 5 or 6 years, (even I've posted about these issues on many occasions over the last 5-6 years) and over those years Bitmain have grown larger and most people on the forum have bought their miners, and DIRECTLY helped Bitmain do what they have done. Actually I find it pretty hypocritical of these people complaining about this one particular change Bitmain has made, but they've bought Bitmain miners with ALL the other issues well known and have DIRECTLY helped Bitmain do this. Oh well. |

So i already did this, only two of my three hashboards show status? Am i eff’d? I am also running 2 bitmain 1600W psu’s to run my antminer and it is on low power enhanced. It seems like it’s the only setting it works on. Somebody help!

2 x 1600 is a lot of overkill. Did you have 2 of them plugged into 1 board or did you have 1 running 2 boards and the other doing 1? The danger of running on 2 psu's is 2 fold. 1) If the one running the controller goes offline the fans stop spinning. The hash board that still has power now has no cooling. 2) If you plug 2 separate psu's into one board you are now feeding in 12V from 2 separate 12V rails With that being said. You can always try to revert to an older firmware: https://support.bitmain.com/hc/en-us/articles/360019493654-S9-series-S9-S9i-S9j-S9-Hydro-Control-Board-Program-RecoveryStandard disclaimer: If you are not sure what you are doing don't do it. If you mess it up and brick your miner don't yell at me. You are doing this at your own risk. Now that the lawyer talk is done. I have not installed the new firmware but I have had it with some of the older ones where 1 board would drop out and going from firmware to firmware would fix it eventually. -Dave |

The good news is that there is going to be a method to boot Braiins OS from an sd card, and then while that is running, flash the controller's NAND storage from it so you could then take out the card move the jumper back and keep running Braiins OS. THEN, you could use the bOS to factory procedure to go back to an older factory release. A bit convoluted, but a solution none the less. While its technically possible to do it right now, it is undocumented so please wait for future bOS releases that will document and expose this new install method in their UI. Here are some tidbits, but please don't try it yet by yourself, you don't want a brick! For the time being, there is a workaround. We DO have a utility call bos2bos.py. It is intended for development purposes. However, it is able to remotely flash a machine that is running bOS SD card to a NAND version.
We will include this anti-evil feature into April/May update So be patient that once again the free open source community is bringing out a solution. |

The problem is I have the new fimware and cannot upgrade. Therefore, i tried to ssh. That wouldn’t happen. Server denied. Then i tried to get into the configure file where they had everything commented. I attempted to edit it but still to no avail. Looks like i still have a lot to learn in linux. Btw, i will need another hashboard. I burn through these things like hot cakes. I had PSU 1 running Hashboard 1 and Control Board and PSU 2 running Hashboard 2 and 3.

I have tried to flash the firmware with the MicroSD in the antminer. It is still running off the March 2019 firmware. I also moved the jpr 4 to the right position so Idk what else to try. There is also no SD kit compatible with the S9 so I tried the Z9+ toolkit.

Right at 100 miners reverted to original firmware via sdhc card at this point. Its slow going, with 2 of us working, we can do about 5 an hour. 19 more to do this week and we are done.

I don't really like that information offsite so I'll paste it here: S9 series (S9, S9i, S9j, S9 Hydro) Control Board Program RecoveryThis method applies to the following situations: - The miner is power-off in the upgrading process.
- The miner cannot start (cannot find IP).
- The miner can only use the default factory workers.
Tools required: - The MicroSD card recommended capacity of less than 16GB. Larger capacity MicroSD cards are not recommended as they are very susceptible to errors.
- A computer running Windows XP or later
- Card reader
Software required:We use the same image as T9+. Download Link: https://service.bitmain.com/support/downloadOn the left sidebar click "Flashing SD Card With Image>>Tools and Instructions to Image SD Card. Scroll up to the page and find t9+-SD Tools.zip. Load t9+-SD Tools.zip to your computer in a convenient file location.  Flashing Instructions : - Remove control board from miner assembly.
- Know your control board model and enable it to flash using the SD card. (See three types of control boards explanation below)
- Insert MicroSD card into computer and format to FAT32.
- Unzip the downloaded t9+-SD Tools.zip and copy the contents to the MicroSD card.
- Insert the MicroSD card into the card slot on the control board
- Power on the control board. Allow at least 90 seconds for the files to load automatically. When loaded, the red and green indicator lights on the control board will blink.
- Power on the control board and access the miner interface. Go to the Upgrade page and Uncheck “Keep Settings”. Flash the firmware and run the miner for 20 minutes.
Note that there are three types of control boards and each of them requires a different way to enable flashing.1. One complete board such as model CRT0401, CRT0402. To enable it to flash using SD card, you need to shift the JP4 jumper to the right as shown below. After flashing completed, power off the control board and shift the JP4 jumper back to the original position.  2. Double boards such as model CRT0302. To enable it to flash using SD card, you need to shortcircuit the AB as shown in the picture below.  3. Boards without SD card slot such as model CRT0301 It doesn't support SD card flashing.  Possible solutions to solve the flashing failure1. Reformat the TF and make sure you've copied the correct firmware. 2. Press the TF softly to ensure it's well attached. 3. Dust and clean the TF. 4. Try with another good known TF. Note: TF card = MicroSD card. This was coined in China to avoid paying Sandisk... BTW: Moving the JP4 jumper is the same method you can use to boot Braiins OS without flashing it into NAND (ie. for safely testing it). |

Hi, Unfortunately there is another type of board. I tried boot from SD several times but immediately after I switch jumper 4 to boot from SD position I got both leds green + red constantly on and nothing happen. After some google investigation I found that my board is missing some chip close to slot as you can see in images :-( I ordered CP2102 UART to USB ( https://www.aliexpress.com/item/1859102520.html) and hope that I will be able enable SSH on secure firmware or boot from tftp to remove secure firmware from my board. Image 1 - Antminer S9 control board Ctr_C41 Vers: 1.20 As you can see there is some sticker with some chinese + TF Card https://pasteboard.co/InjoGnE.pngImage 2 - detail of missing chip .. https://pasteboard.co/InjppJn.pngWill add more information after converter arrive. Thanks and regards, MK
Hi, I prepared guide how to enable ssh on secure firmware via serial console for those without functional SD card slot. I will also add steps how to unbrick antminer without sd card slot. https://docs.google.com/document/d/e/2PACX-1vSu6XGV4Q40TerRPccB7xxTf2sKNkp1Bkwkdz4ILhIaa9qaT-NvZWtFrIBiwpRsG3NRlzvwQkbKyvsv/pubThanks and regards, MK |
