Bitcoin Forum

After some of the more recent updates, Bitmain© has decided to lock us miners out of our own hardware. We have released instructions to restore SSH to allow us to take back our miners and modify them as we deem fit. Along with the ability to flash custom firmware that we will be releasing soon along with others the community makes!




1. Download SSH Unlock Tool (https://asic.to/ssh-unlock/)
2. Edit Settings to matches your network setup. The screengrab below would scan all machines in the last octet of 192.168.1.0-255


3. Click the unlock button for the machine types you are unlocking.
4. WAIT 2-3 Minutes for the machines to reboot from unlocking.
5. Press Remove Signature
6. Congrats you now have ssh root:admin and signature check removed!
Tip: For bulk flashing firmware use BTCTOOL- Download and flash our firmware. (https://asic.to/antminer-s17-t17-optimized-firmware/)

Please visit our site and stay tuned for some awesome releases coming this coming week!

is it applicable to S9K?

If you are running an S9, S9i, S9j, S9k, S9se with May 2019 firmware or older. You can remove signature check using this file: https://asic.to//files/Firmware/S9/signature.zip and unlock ssh.

nice.

i have some t17e new.

i would love 💕 to unlock the t17e.

and back it off it currently does 53th and 3356 watts.

i would prefer it to do 3000 watts not 3356 watts.

i have  16x s17 pro. would love to explore a setting that goes to

35th and 1050 watts on the most efficient end.

i have 2x t17e
i have 1x t17
i have 1x t17+
i have 1x s17

and a mix of 26-27 s9 s9i s9k

i want to explore underclock on all this gear.

basically if 1/2  ing really hurts mining i want to be ready now to underclock all this gear.

Well you're in luck! This works with all S17 and T17 models. (for the unlock and signature check removal)

Ahh I see. Do you want to half it now or half it once the halving comes when you will really need that extra efficiency?

The + is still a work in progress for the 17 series. For the non + models should have it posted by the end of the week or start of next week.

For the S9 firmware in rocketship thread will work on S9 and S9i. You can use BTC Tool to mass flash them. But I would first flash one. Lower the settings and get around 70w/th or less if you can. Then you can flash all the others and there is a setting to scan for other S9's and mass deploy the settings you fine-tuned to the rest of them. For instructions check out this: https://asic.to/documentation/ it will detail pretty much every step involved for the S9. It will also be similar for the 17 series when ready. But 70w/th is def doable with S9. With 17 series I have not even played with downclocks yet but I plan on it once my next machine lands but it should be promising.

If you don't have a computer at the that location Phil you should setup like a raspberry pi with a vpn client running on it. That way you can always just vpn and play with them. (also could then TV into you and help if you needed it)

Update for you all! I decided to make a little tool in vb and also added support for Antminer S15. All you have to do now is fill in the text field as you would previously and then press save. Then click whichever miner you are trying to unlock. After that is done wait a few minutes and then press Remove Signature. Hover ENG flash or RUS flag for instructions.

8 False positives because it is a dropper.... AKA drops all the files it needs from it's resources to your local appdata into a folder like this: C:\Users\Owner\AppData\Local\SSH_Unlock_asic.to_Taserz\ You can see it's just the batch files along with curl, winscp, and the files we are using to remove the signature.

Let me know if it has any bug as I have only tested it with 1 machine but it is pretty straight forward none the less.

SWEET , Love the work !! im glad i found this page ,

going to be deploying a bunch of gear and want to try to do the same

in braiins it has cron tabs and i have edited that through winscp

to curtail very low to no draw during peak hours when i get charged the most per kwh

and back to optimal/full settings during off peak at a lower kwh rate.

are there any examples of file edits ect for the s9/i  and s17pro's

Thanks
Freemine

Update :

when does the s17pro firmware go live ? do you have any testing results ect,

is there the ability to buy the firmware ? instead of dev fee ? for s9/17

Should be live tomorrow. Only dev fee as the risk of someone sharing one without is extremely high.

mine has fw from July 2019, where to get May'19 fw?

If that signature file did not work for you.

Flash using sd card: https://asic.to/files/Firmware/Stock/SD-S9.zip

ps. Just updated the program a little bit. Made it smaller and some translation fixes. Along with pausing the replace script.

I will add more to it later and simplify it a bit more as testing showed some people are bad at instructions xD

where is the download link s17pro ?

The S17/S17e/S17Pro/T17 firmware will be out within the next few days.

Sir, it is really a good news!
I have some questions to ask.
1, It miner only unlock the ssh and the signature functions? not firmware update?
2, It no need to flash the firmware by SD card? Just use the network is ok?

Correct algcool. The new firmware should be out today. Keep checking this section on the forum! We were having issues with autotune that should now be fixed.

If it doesnot need the flash SD card, it is really a good news!!!!!!!!!!!!!!!

That is correct! The added benefit is now I have released a free firmware for the T17 and S17: https://bitcointalk.org/index.php?topic=5208500.0

Does unlock work on T17e?

I believe it does. If it does not let me know and I can add support for it. The latest firmware on S17 might require downgrade before flash.

How do I donwgrade from "Antminer-S17Pro-user-OM-201911051518-sig_4536.tar.gz" to "Antminer-S17Pro-user-MD-201905241708-sig.tar.gz"?

Since Asic.to ssh unlock and signature removal are not working for newest update.

If you jump into the discussion on telegram: https://t.me/AsicTo we have the sd card image to downgrade the S17.

EDIT: Both S17 and T17 can be downloaded here: https://asic.to/download/s17-and-t17-sd-card-image-to-downgrade/

anything updated with the no sd card version? Sir!

What do you mean I don't understand. If you are on the latest firmware you need SD card to downgrade to use tool.

We need to unlock the SSH function, we "must" use the SD card to flash the firmware in the Miner? Can we not use the SD card so that we can also unlock the SSH function?

You need to use the SD card to downgrade if you are on the latest firmware it must be done using any tool. Once downgraded or on earlier firmware the tool can be used to unlock it.

Just created a video showing the unlocking process: https://www.youtube.com/watch?v=q9i_5KYl4Xw

Help
I don't find firmware for Antminer S15 anywhere, I only find S17

Following! trying to unlock SSH in my antminer S9SE, where can i find the downgrade image file ?

https://service.bitmain.com/support/download?product=Antminer%20S9%20SE

Just write to Bitmain support and they will send it to you by email

Hi - Can this software unlock a T15? Thanks!

Yes

FYI : nothing is working on a S17 with this fw version : Thu Dec 5 15:54:50 CST 2019

SD card flash is the only way on those to unlock it. You got to downgrade her :(

for SSH Unlock on s9j-i is add dev-fee on device or not  is it free use i need only change bminer config for fan power

link for Unlock SD images.zip for s17+ from website keeps resetting and does not finish downloading. please advise

http://asic.to/files/SD%20images/SD_S17%2B.rar

I tried your file in this link for flash my asic (t17+) with SD card but after flash my asic didn't wotk correctly . I can't login to my asic config ip!!!
 whats the problem?!!!! :(

https://asic.to/ssh-unlock/

Did you first do the SD card flesh with MPtest firmware and then flash T17+ firmware for that machine via "upgrade" on your miner's ip?

try root root or root admin

Hi, do you know if beyond unlocking if there are any alternate firmware options for the T15? I might try using this tool on it, what's the main purpose of this to be able to overclock and/or undervolt them? I saw your one reply to this thread over here too but looks like it died out: https://bitcointalk.org/index.php?topic=5201015.0

Thanks,
Dan

This thread is very confusing. It seems to purport that there is a "SSH Unlock & Signature Check Removal Tool" available for download, located on asic.to's site at https://asic.to/ssh-unlock/.

That page does exist, however while it talks about ssh unlocking, there is no link for an unlock tool download whatsoever! Simply a download link for a SD Flash drive image file to upgrade to asic.to?

So lets get the facts straight here and put up correct info or update us on what has changed.

My reading of this thread, and after watching the posted video, leads me to believe that the unlock tool is a windows program you run once you have your miner configured to support it.

Where do you get this tool from?

Noted on that very website you just linked:


Bitmain locked newer units and those are no longer able to be unlocked with the program asic.to was providing so they removed it altogether to avoid confusion. Title of this thread hasn't been changed at all afaik.

Just do the SD card flash if you want to change firmware or unlock SSH.

Yeah SD flash is the best way to do it. We are not going to release the other means of unlocking the 17 series remotely at this time.

this is also possible, you just need to re-install dropbear: D

Yes that is the public way.
