Something nastier is coming for the S17 family, meaning people who upgrade their firmware won't be able to replace it unless a chip is de-soldered and a new one soldered back in (replaced) on the controller.

Sounds like BM is resorting to using a WORM (Write Once Read Many) programmable memory chip to foil the 3rd party folks.

That not only sucks for tweakers but I'd think will also make it impossible to upgrade even using BM's latest firmware as it is released...
Crap like this is why I refuse to use BM gear any more.

You can use a procedure involving the T9+ image and a micro sd card, while the guide to do it was moved into some zip file, its still in the Bitmain support page (for now). Its nearly identical to testing Braiins OS: Just flash the sd, move jumper jp4. Boot the sd card and wait (blindly) some minutes for the T9+ firmware to be flashed into nand, leds flash signaling completion. Then restart and browse the miner's page, you can now upgrade to the S9 2018 firmware and stay there. It won't hash until you do install the S9 firmware...

Something nastier is coming for the S17 family, meaning people who upgrade their firmware won't be able to replace it unless a chip is de-soldered and a new one soldered back in (replaced) on the controller.

In other news, Braiins OS for the S17 should be (hopefully) coming in July.

So ... you'd be best to just do the simple BM downgrade to a non-SSH lockout version, then install braiins

A 2019 firmware of Bitmain doesn't permit you to downgrade to an earlier version, you are forced to remove the signature check to load any other firmware than a 2019 firmware of Bitmain.
And I never installed the Asicseer firmware, I just removed the signature check with their installer. You can do this without installing firmware.

...
In the end the solution was quite simple and it even is much easier than installing Braiins from SD-card.
First I used ASICseer to remove the signature check, and immediately after this I used the Braiins OS+ Web Package to upgrade to Braiins from the web interface.

No need to flash older Bitmain firmware first, and no need to take the miner apart and move a jumper back and forth.

Well the Asicseer install does a LOT more, than instead, just installing an old BM firmware that doesn't have the SSH lockout.
Ass firmware also, as is obvious, violates the cgminer license.
It also tracks your miner back to them (and installs various other software also ...)

So ... you'd be best to just do the simple BM downgrade to a non-SSH lockout version, then install braiins
... and stay away from the Ass firmware since that could be problematic.

P.S. as usual the mod here merits a post that suggests (temporarily) using a firmware that violates the cgminer license ...

[NEW RELEASE] Braiins OS+ 20.06 Release & Roadmap Update

We’ve just released Braiins OS+ 20.06. Here’s some of what’s new:
• Saved autotuning settings (previously available only with the nightly build)
• Run custom commands in batch with BOS Toolbox
• Auto-upgrade
• Dynamic Power Scaling
• Support for Stratum V1 passwords and yiimp-based pools (e.g. prohashing)
• IP report button now works correctly

You can find more details on the release here: https://braiins.com/news/development-update-braiins-os-20-06

With this release, we will now shift our full focus to supporting more hardware, starting with the S17 and T17 models. In other words, this is the last major release specifically for S9s. We anticipate a beta version Braiins OS S17 and T17 support within the next month, with full autotuning Braiins OS+ support coming in a subsequent release.

Wanted to see what everyone thought was the best settings for S9 13.5. I have it hooked to a Antminer 1600W PSU via 220v. Have autotune running with the PSU power set at 1440w. Currently pulls between 13 and 14.3 TH/s some times dips a little lower for a bit. Board temp is around 70c and Chip temp is around 87c.

That's no better than factory stock firmware. Are you mining with AsicBoost ? That's the only thing I would think that would be the cause. Some pools have different URL's for AB. With AB On, you would, with stock Bitmain firmware, be drawing only around 1250 watts, at the normal 13.5 hash rate. With AB on and 1440 watts you should be at least 15 Th/S, with factory firmware. I know with other 3rd party firmware I got a tad over 17 Th/s at 1550 watts

i assume you had the jumper correct and you could boot the sdcard.

Even with the SD-card in the right orientation and the jumper in the correct position the controller boards without the U6 chip do not boot from SD-card.

Thanks for the Firmware, Seems to be running pretty good. I have it installed in a s9. I have a question though. With auto-tuning turned on, Is there a way to adjust the fan speed/profile without needing to re-run the entire tuning process again using the web ui?

With the halving well behind us and with summer coming I decided it was time to install Braiins OS+ on all my S9's for some more efficient mining.
All my S9's are running the March 2019 firmware from Bitmain that crippled SSH, so I had to use a SD-card to install Braiins.
But about 25% of my S9's are missing the U6 chip behind the SD-card slot, and these machines won't boot from SD.

What is the best way to install Braiins on machines in this situation?

I think you will be forced to use the serial port hack, this is very advanced i think there are only a couple of topics that talk about it. I think you can force flash an older bitmain firmware with ssh access and then move from that.

Good luck if you decide to try it, post back your results!

'The right to privacy matters'

i did a few boards with the style sdcard holder.

it is the upside down version of my one on the video.

so you indicate you know to flip the sdcard.

i notice the pins on the four jumpers are set to boot from nand not from sdcard.

i assume you had the jumper correct
and you could boot the sdcard.
i assume you then moved jumper back to boot from nand and then found out it never loaded.

please confirm.

My controller board looks like this:

The orientation of the SD-card is not the problem.

edit for clarity. This interests me please give me a minute

Here is a video

Those are interesting results. You should give more chance to the autotuner, with a very low powerlimit it should outperform your manual settings. The only problem is the time it takes until it decides its "stable" (can take several hours, less with a lower powerlimit)

Also, the settings from the autotune are only saved if you use the nightly version, which you need to enable via ssh with the command bos nightly_feeds on

This only works in the miner you have installed into nand, until they release a new SD image.

I took this screen shot
note sd card
note jumper is moved
note I marked off the chip you say is missing.

I Think you may have an issue.
Does the card fit in correctly?
Is the slot like the slot in my video?
Note I say in the video sometimes you must flip the card.
As the slot was flipped.
That is an easy fix.

but if that is not your issue I think you may not be able to fix them.

Everyone is asking this lol. All i know so far:

They claim to have it working with an S17, but nothing has been released yet. It is their main goal for the next (non nightly) release. Nightly is for late bug fixes, requires installing into NAND and is enabled via ssh with the command: bos nightly_feeds on.

I have no idea if the other models are close or different enough from the S17 to require separate images, or more testing/changes before getting support.

The other day, when nicehash was paying really high was on the sha265 account not the sha256asicboost, soo there is a point here, there is something bad, a bug or something that not let the Braiins software connect to the sha256 servers.

That btcv2? craze also spread to the sha256asicboost rentals as well...

I have used it with Nicehash just fine, it works. This is the URI i used:

stratum+tcp://sha256asicboost.usa.nicehash.com:3368#xnsub

Its simply the asicboost port. I haven't tried non asicboost, but see no point when asicboost works just fine.

yep it works with asicboost

And that is good enough for me.

I do like the april edition of it.

Do you have any idea when it comes out for

nice hash has always been flakey.

Now that I am building modded 2 board s9's with braiins designs to run quiet and on 120 volts.

A lot of people want to run them on nicehash and on solo.ckpool

I sold pairs of them and one will be point to solo one will be pointed to nicehash

they are space heaters first. miners second.

I set them at 8.05 volts and freq 300

I swap out the fans which makes gear quiet and caps top speed at

8.4 volts and freq 450

fans are set to 50%. which is 1600-1700

and you have a 350-360 watt space heater.
