luckily, I did not have to unplug bad HU or board to continue to mine. Seller let me know there is firmware to allow to mine on good boards. since I was able to get machine to mine, I would not commit to trying to update firmware. My version is below. I did out of frustration do a factory reset and that was a nightmare for me. I had a hard time getting my pool back into system but it ended up being a stupid mistake on my part. looking into the manual thats on mfr site, I can say, I would not want to update firmware, afraid to make a mistake and ruin machine. good luck! I have since given seller info and waiting for them to ship me a HU.

Firmware Version21022601_4ec6bb0_5f74eef

mfr said parts to seller next week. I love the miner, wish they sent spare parts with batch's. runs a sweet 56-66t on 2hu. normal mode.

i cannot say it was anyones fault that the chip shortage or issue, my March batch came out 85th instead of 90, and the deal was accept or cancel. that was brutal ontop of premium cost.
 

I wont or should take back that they passed the buck. I'm a newb and maybe need to understand how things work. looks like the customer has to talk to mfr avalon to get log read and then instruct blokforge to support. I was on here in panic since I hadn't heard back from avalon at the time. I went all in on the machine and when it went down my anxiety took over.  I have since realized that there were truck loads in many batches sent out and there are just a few of us talkin bout issues and they are communicating with me and look to support. agree with the comment that I could still be waiting for a machine...

HagssFin,
I greatly appreciated your help. I was educated by you on the log and had the forethought or afterthought to send it as a reply to my initial email. I wont throw names around as I am at their mercy, lol. The fella at Avalon replied and agreed that I need a hash board. And to work with blokforge supplier to fullfill this need. so I am happy to report that they are supporting the customer. I would think that if the market wasn't as strong at the time that you would have gotten one to review? maybe not as they have Voskcon review video already on their page, next to the manual in support page. I like blokforge but was a bit dissapointed that during my chat to resolve issue I wasnt assured that it will be taken care of. To him it was standard reply, but to me the machine I spent a handfull of bitcoin on was huge to me.  When it broke my lil world fell apart, kinda.

I lost a board, red hash2 on root menu and the H3 temp reads 32degrees f. I see the center board light is out so I removed it but chickened out on removing heat sink screws, don't know if there is anything I could do if I did find something....emailed and wtg response from Canaan.
