I will tell you the problems about Baikal miners.
Actually, there is no any problem on Baikal miners but I see some problems.
Well if you have any similiar problem, there is no any solution. The Baikal maybe find a solution.
**********************************************
I didnt see any problem on the Baikal Mini miners.
I didnt see any problem on the Baikal Cube Miners.
There is only one problem of Baikal A2000 Giant+ Miners.
**********************************************
Baikal A2000 Giant+ has two board.
I have received the miner. One of the boards has a strange problem after one week.
It shows 12 chips instead of 24 chips.
No blue and no green light. Only red light is on.
And no submitted shares and I dont see it on the pool.
By the way, I see this problem only on a miner. There is no any other Baikal miner with this problem.

I tried to find solution but no any solution.
So, I have requested its firmware from Baikal. And I did everything correctly.
But there was a problem.

Baikal sent me 4 mcu, I have changed the mcu at two times.
The same problem. Nothing do to be done.
There is no solution.
If you have the same problem, just send your miner to Baikal.
I think, they will find a solution.
We cannot find a solution by ourselves.
EDIT
I sent the board to Baikal. I paid 55 USD for the shipping.
Baikal repaired the board for free. I paid 55 USD for the shipping.
Total cost: 110 USDBaikal didnt request money for the repair. it s so good.
If you have this trouble, just send the board to the Baikal.
If your miner is in the warranty period, you will not pay for the repair.
