How about running the miner with Braiins OS through an SD card? I already posted the link above on how to do it?

You don't need to flash the unit you just need to boot your miner through an SD card. Braiins OS currently do not have SD card firmware that can flash the NAND but you can boot Braiins OS through an SD card.

well i almost got braiins os on it but its saying Unsupported miner NAND partitioning. So im not sure the work around on that. I looked around and i couldnt find anything. im starting to think i should just sell it on ebay and call it a day. I just dont want to give up yet.

It is a G29 and I was just trying to use ubuntu to install braiins os and i almost did it until it asked me for the password. I couldnt figure it out. I tried admin, dragonadmin, blacksheepwall, and dr4g0nhash. Any thoughts on that? mind you i have tried factory resetting it and all hard resets.

Would you mind checking the controller physically if the board name is G19 because there is some firmware out there where you can flash the controller through TF Card? It might fix this issue.

Or you can try to flash it with Braiins OS but make sure to look for the controller unit model so that you can flash it with the right firmware.
You can find old firmware for g19 and g29 here https://feeds.braiins-os.org/

Then the guide on how to boot BraiinsOS through an SD

unfortunately I have tried all of that already, im pretty certain after troubleshooting that the control boards is dead. I heard installing braiins os might fix it. Any idea on that? thats my next step. But im not to familiar with command lines and ssh. Control boards are very hard to find as well.

I'm not so familiar with dragonmint logs but based on the logs it seems there is a connection problem between the controller and hashboards.

What I would like you to try is to replug all cable PSU and data cable between the controller and all hashboard.

If it didn't fix your issue try to run the miner without two hashboard I'd like you to test hashboard one by one and maybe one of the hashboard is broken.

Could anyone help me to narrow down what is going on with my dragonmint T1, i will attach the logs. but it seems all 3 boards wont work for some reason. I thought it was the psu at first so i bought a brand new one and thats not the case. I also updated firmware. (im not using brains os) i tried resetting with a few different methods as well. I think i narrowed it down to the following line but im not sure what it means. So if someone could point me in the right direction that would be awesome, so i can get this thing back up asap. Id hate to think all 3 boards died at once. So could it just be the controller?





here is the log that loops:
