Why not start using Electrum for Android phones instead? It's easy to use compared to mycelium the only difference is mycelium supports other altcoins but Electrum only supports Bitcoin.
Since you have a PC then you can choose which one you want to make your cold storage the mobile phone or the PC?

Take note make sure any of these devices should be disconnected or never connect to the internet. Cold storage should not have any connection data to the internet and only a QR code or USB flash drive is your way to transfer raw unsigned/signed transactions.

This is not the right place to fool around you maybe try it on another forum.
Based on your image it generates only one address with one seed phrase.
The seed phrase contains a huge amount of public keys and private keys, not just one.

I suggest you start on flashing or boot it with Braiins OS before you try PSU but there is a big possibility that the replacement control board could defective.

Do you have any extra miners for testing it would be easy to troubleshoot if you have an extra s9 miner?

Or check the test points of your hashboards to make sure your hashboards are fine you can follow this guide below to troubleshoot the hashboards

- https://www.zeusbtc.com/manuals/Antminer-S9-Hash-Board-Repair-Guide.asp

This unit looks like an Aisen A1 miner usually to this unit if it has a bad fan it won't hash so maybe the fan you replace is not compatible.

Would you mind to check the wires of the old fan and maybe the position for signals for both speed and PWM signal is not in the right position. So try to replug the pins in the right position.
Just like on the s9 miner have 4 pins yellow and blue must be in the right position before you plug them into the miner.

Why not strip the wire instead and cut the two lines the data+(green wire) and the data-(White wire) then two negative(Black) and positive(Red) should remain then use heat shrink to cover it back. If you need the cable for other things to transfer data make sure it's not related to your wallet or any important data then you can strip it again and connect those two cut lines.

Or buy an adapter like this below then put a tape on the two pins in the middle

Any grease spray might be work but I think the bearing should be replaced if grease does not work then your last hope is to replace the bearing the only problem it looks like it's hard to remove the metal under that fan motor. It seems that you need a puller to be able to remove the metal part on the motor.

If you have a motorcycle tool you can may be able to pull that metal part the tool looks like this one below

If you want to spend your BTC from your paper backup you can use Electrum on your phone but like the above said it's risky if you import a private key into a device that you usually use for online activity.
You need an extra phone or PC if you want to make a safe transaction because one of your devices must be offline and never connect it to the internet and one is a watch-only wallet where you can able to make unsign raw transactions.

I think he means on the first question he talking about other wallets?
If I'm right then other wallets like Electrum can be used as a cold storage wallet with no internet or any online connection or without hardware wallets.

If you are going to spend BTC from your cold storage you will need to make a raw transaction from the watch-only wallet you can install Electrum in android and import your master public key or use coinb.in to make a raw transaction then sign it with your cold storage wallet then transfer it back to your watch-only wallet and then broadcast. It's simple as that.

Try to flash your miner with SD card and lets hope that its just a software issue.
You can follow this guide below

- https://support.bitmain.com/hc/en-us/articles/360019493654-S9-series-S9-S9i-S9j-S9-Hydro-Control-Board-Program-Recovery

Then upgrade your unit with autotune firmware from bitmain.

If the issue the same then I suggest boot your miner with Braiins OS you can check their thread from this link below.
It can bypass the temp issue or ignore that error.
- https://bitcointalk.org/index.php?topic=5036844.0

Based on the logs below read temp error it means that your control board can't detect any temp signal from your hashboard.


One of your hash boards might have a broken temp sensor or ribbon wires that are not plugged properly.

Try to re-plug all of your ribbon wires then check it again through logs or if it's hashing.

If still do not work then you can bypass this issue by flashing your unit with modded firmware like asic.to firmware or Braiins OS.

It's not a problem if you mess up if you already have a backup seed phrase you can anytime recover your wallet with your seed backup.

But if you have important files that you want to save why not transfer them into an external hard disk if you don't have HDD then a USB drive?

Windows 10 would be enough since all new Electrum are running fine.

Why not use other exchanges like Kucoin exchange based on their terms they do allow you to trade without KYC verification.
So you can also able to trade on their P2P exchange.

The only problem is that they only have a few listed sellers on their P2P unlike Binance on their .com domain but still worth as your other option to trade P2P.

If it's clean straightforward firmware without extra fees why don't you just use the firmware available from the Bitmain download page?

The only problem is they do not have an open-source but they are trusted because they are the ones who manufacture Antminer. So it should be trusted.

Or do you have other reasons why you are looking for open-source?

Based on your logs it could be a PIC flash corrupted or fried PIC chip.

What I would like you to try is to run hashboard one by one you can follow this guide "Antminer test one by one"

Check the logs again and update here for changes.

The other thing that I noticed from your logs is that PCB temp has an abnormal status so there is a big possibility that your hashboard is overheating it could be short capacitors or dead sensor.

I think you were confused about the chips why not play first with a small amount of around 0.002 and try to split them or one of the chips like 0.001 to donate it increases your anonymity.

Then hit withdraw you should see a private key and you need it to import it to Electrum wallet and send it anywhere you like.


If you can't still don't know how to or understand how it works I suggest you read this https://bitcointalk.org/index.php?topic=5256899.0

It is the same as other people experienced on Windows 7(and me as well) that they can't able to use a higher version than 3.3.8.

If the Bitmover suggestion does not work your last hope is to upgrade your OS to Windows 10 which have better security, feature, and support than Windows 8.1(it will end support next year) and all new version of Electrum should be working as I tested them.

Can you tell us the reason why you don't want to upgrade it to Windows 10 since they already suggested it many times from old replies here? System requirements?
If it is just for the files then upgrading does not delete old files it should be still there on your hard drive after an upgrade.

If you read the posted link above it was posted 2 years ago so it means there is a possibility that miner are sold out and that time the price of Bitcoin is around $9k compared on the price today so it possible the prices are changed.
However try to contact him and maybe he can able to give you some other source with cheaper price than $439 you can maybe get them for around $150 or around $200

According to this calculator https://www.mycryptobuddy.com/BitcoinMiningCalculator
You can reach the ROI after 1yr and 9 months. If you can get cheaper used or 2nd hand ASIC miner you can get ROI fast.

Use this tool to find the ASIC miner below then set it to 0 power cost just sort them with the algo and profitability.

- https://www.asicminervalue.com/

Or try to contact offordscott for a used miner at a cheaper price. He sells an Antminer s9 before for $85 each which is way cheaper than your source.

Why not just remove the one hashboard from your miner if your miner is running at 3000w removing one hashboard will drop to 2000w?
Or you can try to run the miner at low power mode I don't know how much wattage will drop but I guess it will be around 2kw.

If you are using Braiins OS it has an option under miner>configuration>autotuning where you can able to limit the power consumption you can set it to 2000w if you want to run it with that power.

Weird you have miner type Antminer X17 did you flash your control board with a different miner? Or a different source than Bitmain?

I suggest you try to flash your miner with SD card firmware from Bitmain here https://shop.bitmain.com/support/download

After you flash it with an SD card upgrade it to the latest version available on the Bitmain download page above. Then test it again.

The other errors under this "no SN got, please write SN to /nvdata/sn" might because of mismatch serial number like the above said you need a code editor to fix this issue.
