I tried to search on Google but you can only find PCB temp for this unit.
Also tried to search for the BM1397 datasheet but no one share it yet.

I think the Asic chip max temp for the 17 series is usually around 110c-135c.

My suggestion is better run it in auto mode instead of running it in manual mode because if you set it near the max temp you just likely frying your chips to death.
And it is always better to keep them cool.

PVT_T0 it is a list of the temperature of 0 hashboard meaning it should be the first hashboard but thats not the only way to identify which hashboard is bad check the HASHS on the logs sample this one HASHS[ 1 0 0 ] if it shows the same as this then the first hashboard is bad.

Why not share all of your logs? It doesn't have any API of your miner so it is safe if you share the whole logs instead.

Another thing is the troubleshooting is available on Canaan support under this link below and then go to the manual then download the troubleshooting pdf file.

The image diagram is free its publicly posted there but when I trying to download the docx or the repair guide from Whatsminer M3 it ask for MHC payment check the screenshot below.

Are you sure? He is active here recently it would be better make a separate thread about devtome because this thread is for Gekkoscience.

Or bring your concern to their official thread here

Ok I just PM him for you and expect for response through PM.

The raspberry pi only use to run the software the USB stick miner we talking about is Compact F it is an ASIC miner in USB stick that support SHA256 meaning you can still mine Bitcoin using this USB miner.

Actually, about solving a block I heard the news who mine solo with this miner and luckily mine a 6.5BTC on ckpool minus 2% fees.

Are you sure you are selling them? Do you own those guides?
Most of the guides and docs can be downloaded for free from their support.

And also you can download them free from https://www.zeusbtc.com/ASIC-Miner-Repair/

DCA only works if you know that the price will rise again soon true traders do not use this strategy they mostly do stop-loss to cut losses and without analysis, you will never know when to buy the dip.

Due to recent news about Binance and Coinbase, there are many investors pulled out their investments from exchanges. So there is still a possibility that the price may decrease more if you don't use stop-loss you may lose more.

Unless you believe the issue on both Binance and Coinbase will solve early then DCA will work and if you can wait for long to hold while buying the dip.

Trustwallet has some bugs like this issue even the transaction is confirmed. It's a well-known issue.

Would you mind to try to connect to another internet or use VPN and maybe there is something in your current internet blocking trustwallet to connect online.

If it didn't work like the above said you can import your wallet to Electrum.

Take note that lightning is still experimental which is why most of exchanges do not support it yet like Binance but there is news that they are going to support it but only for small transactions.

So I think yes due to current network congestion having a lightning channel can save you more fees than using Mainnet.

There's a guide here that you can follow if you want to run a compact F USB miner check this one below to get some idea.

One compact F is not enough to make a quick buck I think 10 or more with a hub will make you $1+ weekly.

Even if you withdraw it to Electrum you will still pay fees. Opening channels on Electrum still need to pay fees.

If you want to withdraw with low fees the only option you can pay low fees is by using BNB smartchain but Electrum doesn't support it.

I already check Binance fees on withdrawal they currently ask for around $5 for both mainnet and Ethereum chain.

There are many issues according to your logs not only overheating it also has problems connecting to the pool due to high netfail and bootby also like the above said the middle hashboard is abnormal or it might have connection problems you can try to clean terminals and replug them first but if it didn't work you'll need to replace it.

If you want to solo mine why not use https://solo.ckpool.org/ so that you don't need to host and wait to download almost 500gb blockchain?
I never heard someone succeed in mine solo with their own node unless you run your own pool.

If you want an open-source pool then you can check this one https://github.com/tpruvot/yiimp
So that you have your own stratum mining pool and I'm sure it will work to mine solo.

If you talking about ETH then you should make another thread to the altcoin section to get the right response.

And I think there is no app yet for ETH that can make offline transaction but they do have a web version that you can also with your phone check this link here

Nunchuk requires an email and there is no way to make a wallet on this app without the email. So what's the point of collecting our email? Maybe because of their cloud service but it is still not safe to keep our private keys to any online storage.

I also check their PlayStore reviews most of the reviews look biased and fake the only real reviews there are those that give 1 star.

Never seen any exchanges yet that they shoulder stuck transactions while depositing on their exchange. They only make transactions once you already trade your deposit coins from their exchange and before you can trade the deposit amount it requires 1 to 3 confirmations before you can trade the deposit amount.

Can you tell us what exchange you use where they transfer and do CPFP from your deposit address to their own wallet?
I usually see all my exchange deposit address it only transfer once you already use it to any of their services.

I never heard that there is a custom firmware for this unit I also tried to search but I can't find any.

If your purpose in finding custom firmware is to overclock this unit you can try the procedure here below

About the pool where you mine you are mining on Solo pool meaning you are the only one who mining if you are lucky and found a block it would take years to solve the block with your current hashrate.

Another thing is that if you switch to another pool with a fixed payment then you will get a negative profit due to electricity unless you have a free power source.

I think it would be better if you try to flash the unit first because sometimes this kind of issue can be fixed by flashing or updating it to the latest firmware or try SD card flashing.

If it didn't work then we are sure that is a hardware issue based on your logs the 3rd hashboard only detects a few ASIC chips so if you want to continue mining you need to remove the 3rd hashboard.

Or like other newbies did to fix this kind of issue without the BGA hot-air tool they put this broken hashboard into the oven for 15 minutes.

There is no problem to use xPub to import it to Trezor Suite Lite about security risks since it's a public key your wallet is still secured but sharing xPub have privacy risk because they can monitor all of your wallet addresses and transactions.

If you are planning to make some transactions with Trezor Suite Lite on mobile make sure that your phone is not compromised because there is a possibility if there is someone can monitor and control your phone without your consent they can make a transaction while your Trezor connected on the same device. However, since their lite version for mobile is only made for monitoring your wallet only use it to monitor your wallet addresses and transactions.

And take note this app is new and currently does not have open-source yet so we do not know how safe the app is.

That's a weird issue without the kernel logs it's like we're guessing what's wrong with your unit but if flashing it solves your case then that's fine. Sometimes unsuccessful flashing may cause some issues I always try 2 to 3 times flashing them before deciding if it's a hardware issue.

What firmware did you flash it again the latest one?
Why not try their TF card firmware?
