You sent 100k sat and received only 50k sat in your b wallet?

It shouldn't be 50k sat unless you mean you sent 50k sat and all of your balance is 100k sat and all of them were sent to your address b and the random address. The above posts are right it could be your change address because the Bitcoin core wallet change address is enabled by default. So every time you made a transaction it will generate a new change address. it's your change address where you receive change of your BTC.

Sample you buy a candy worth of $50 and you only have the whole $100 you pay the seller with $100 and receive a $50. The difference is it generates another address where the change amount was sent to that address.  

If you don't want to use change feature on Bitcoin core you can change it on bitcoin.conf by adding this line below

It's a clone version of s19 and I search a bit and it's only posted on the bdlcyber website and Reddit with deleted posts which is suspicious.

Do you have this unit? Or else it is a fake miner without a physical machine?

I don't know about the control board but in the hashboard they mostly use code editor to know the hashboard serial number or you can use it to replace the serial number.

Code editor is only support Antminer dashboard and this is what it looks like below.

Mostly what I heard here on the forum they use 555 timers to make a fake fan signal. There are some fan simulators but if you know 555 timers it would be enough to give a fake fan signal for this unit.

Read this thread below to get idea about 555timer

What exchange do your coins come from? Let's see maybe there is an issue between that exchange and Coinbase.
Are you in the UK right now?
You are living in a very strict AML law since you transferred a very big amount of coins it will take too long to verify if you didn't submit what they ask.

What I think is to try to submit what they ask you said their email is in your junk why not try to submit what they ask even if it's late?
Use the contact email they provide from your email to submit what they ask.

Do you still have the seed phrase from Blockchain?
If the seed phrase backup is your wallet from blockchain you did the right thing importing it to Electrum should show your wallet by enabling BIP39 and using the right derivation path.

I suggest you read this one on how to import blockchain seed phrase to Electrum wallet from this link below

- https://blog.blockonomics.co/how-to-restore-blockchain-com-wallet-into-electrum-f593ec79ab3d

Take note of the addresses you have from the Blockchain wallet if it is a legacy or segwit wallet because they have different derivation paths.

Where did you get a replacement wire? It will melt if you are using very thin wire or cables.
I'm a bit confused do you have stocks of hashboard as a replacement?

What exactly second mode are you talking about?

A mostly short circuit is the reason why wire and cables are melting without a multitester we do not know if the hashboard is shorted or not.

If I were you hire a professional Hashboard technician to repair your hashboard you can check this https://www.zeusbtc.com/ASIC-Miner-Repair/

You can also get an idea of how to repair hashboard at the bottom of that page.

Actually, that log is related to configuration since the model of his unit is t17e it will show you 0x 7777777 but if you have different t17 series then you can have a different one.

Just like this for s17+


So it's normal if you are referring to this.

Actually, Bitcoin doesn't need a bank you can have a wallet that you can use as a bank that is decentralized no one control it except you, unlike banks that are actually centralized and monitored by the government.
Another thing is Bitcoin can be exchanged without banks there are many exchanges right now to exchange Bitcoin into FIAT. Or you can sell Bitcoin on P2P sites.

I search a bit and I think there are some banks that support Bitcoin not globally only a few countries that support Bitcoin.

And I think the reason why they do not support Bitcoin is that they don't want all people to know about Bitcoin. Banks are business that needs people's money to save on their banks and use them to give a loan to someone and profit. And I don't like their very small interest per annum.

So are you talking about the transaction fee or the withdrawal fee?
You can imports them in Cointracking manually if you don't see the deduction of fees in your Bitcoin from the Binance wallet to the Cake Defi wallet.

I think it would be better if you read the Cointracking guide from this link below on how to manually add withdrawal and deposit fees.

What exactly modification do you plan to do with the T17 unit?
Are you planning to replace the fan?

Or do you plan to modify the firmware of this unit to force the fan speed to full speed?
Are you going to replace the fan with lesser noise?

There is no problem replacing the fan just make sure it's compatible with your unit and make sure the wire from your new fan is matched and it is in the right direction before you attach it to your unit.

This unit is not the same as the old model of Avalon where you can able to flash or upgrade the PMU there other might be issues why the PSU fans running fast.
You might be bought a defective PSU or it maybe there is something in your unit that cause this problem like short circuit or PSU compatibility issue.

What is your current outlet voltage?
Can you copy the API logs and post them here maybe we can see the problem under your logs.

Chain 1 got some error at the first run but it works for a while. Unlike chain 3 stop working causes a low hash rate.

Would you mind trying to run them one by one or only chain 3 if it can run stable and know if the PSU is not giving enough power?

Also, try to clean up all PSU terminals and swap all cables to another hashboard then check for changes.

You don't need to download anything if you are using Windows 10 you can use IE 11 since the error shows that internet explorer or above will work.

If all suggestion anove do not work then try this browser below.

- https://www.waterfox.net/
I mostly use this tool to use in SEObook plugins.

I hope next time you need to learn how to explore a bit finding the SD card firmware.

Anyway, Im going to give you a direct link for SD card firmware that you can download from this link below

- https://file12.bitmain.com/shop-product-s3/firmware/024b413e-807e-4fcd-afe5-b1804289b265/2021/05/31/11/AntminerS9SE300M%E5%8D%A1%E5%88%B7%E5%AE%9A%E9%A2%910730.rar

I just put them in naked URL so that you know it was directly from Bitmain page.

Ok then try the firmware from this link below

- https://bitcointalk.org/index.php?topic=5253966.0

Make sure to contact the author first if someone already tested it without any issue. The thread is related to s9k but according to the author the firmware works on s9se and I do not know if LPM will work on s9se but you can try.

Is that Love core Aisen a1 miner?

Actually, there is no official support for this unit here or website but I will try to help you find a solution to your problem.

Would you mind posting the whole logs make sure it is the whole logs and put them into the insert code tag a # button you can find them when you edit your post above or if you have limited character use pastebin.com and paste the logs there and paste the URL here

For now the only thing that I could suggest is to try to flash it you can download the firmware from their old link below

- https://pan.baidu.com/s/19lVmLi85rNEzgKoVImAaQg

extraction code: n7h3

Much better read the SEC about this if you want to make this project legal check this link below

- https://www.sec.gov/ICO

It's not easy to make them legal you need to be familiar with regulatory requirements and follow SEC regulations.
And I think about your question I think you will need an official paper or white paper about your project because they will review what you are planning about your project.

Have you tried all my suggestion above? If not do them first and update here.

But it looks like your hashboard is overheating?
Can you try to adjust the fan speed to higher or maximum to test if the issue is over temp.

Check this guide below on how to find the hidden fan control.
- https://bitcointalk.org/index.php?topic=5202112.0

Also, try the low power mode, and let's hope it will run normally.

Look at your ECHU it shows abnormal mostly a sign of overheating and these negative values on a few chips are also a sign that the chip is overheating.

Would you mind to try force your miner to normal mode? According to your logs, it's running in performance mode.

Or try to adjust the fan speed of your miner because it's running at a low speed around 31% increasing the fan speed might help to avoid this issue.
