bad business practice from STRONGU with how this rolled out

[fccs]

These were the biggest piece of junk miners I ever bought.  2 of them I noticed are completely dead now.  Won't even start to try hashing.

Hello guys

First of all, sorry for my bad English. Well I have a problem with my stu-6. Yesterday it was mining normally, I turned it off for a few minutes and when I turned it on again (without touching and changing anything) it stopped working.
Now none of the 4 blue leds light, only the two yellow lights of the ethernet cable (and neither of them blinks, just light). The fans do work but as I say none of the 4 blue lights and no hash at all.

Someone could help me please? Thank you

[Crippt]

Thanks for your answer Bren77 but how can I conect with the miner to upgrade the firmware with no blue leds light and the ethernet lights lighting but fixed?

[Crippt]

Please, some help...

Hello everybody! Can anyone sell me a working hash board on the Strong U6?

[DaReaLDeviL]

Same thing here... Miner just died and no more lights on it - just the lan leds are blinking .

Out of nowhere all stoped. Any solution for this?

It only works in cold rooms. If temperature of the room ups to 25 celsius it burns,  sooner or later..

I see some ads on google and they advertise these miners has a hash rate of 660 GH/s are these fake numbers ?
If you check on the StrongU website i see there is only 1 model with 420GH/s

Seen there are still people having issues with the strongu bins..

I guess one of the most common failures ist the freq stopping at 170 and no hashing at all.

1.) Dismantle the whole creature and gently check if the tiny capacitors on the hashboard are still properly soldered onto the board. (470 yF/ 16V)
If not replace them with equal ones with wirelegs. It's a pain to preheat and solder the original ones with the shortlegs..

2.) Fire up the bin, wait 10 min. Get the Antminer D5 firmware and flash it. Yes right! the antminer Firmware. An Error Message will occour, but at least the old buggy shit will be wiped.

3.) Let it run for 10 min and get the strongu U2 firmware (SIA). Flash it and let it run for 10 min and then use the original firmware. Flash it.

Now it should find both boards again and start hashing. It will take a couple of minutes to reach the max.

Another problem are the fans. To run them more silent the Antminer fans are a good choice. (Nidec Ultra Flow, 1.63A) but make shure both are new. If one of the original fans start to die the miner will go crazy.. (resulting in the software to kill itself?)
On the control board there's a 3 pin connector next to the 4 pin fan connectors. The black wire of the fan plugs should be on the same side as with the 3 pin plug. In case the replacement fan wires are interchanged use a plier and pull off the plastic socket und turn it 180. (or solder the end of a dead fan in the correct order onto the new and most likley to short cabeled new fan)

Anyway.. don't forget to reset the stratums with your own credentials and keep hashing.
