Yes, that is exactly what happens. The salvaged wallet file doubles in size for some reason, and when loaded thru the core it says its corrupted.
Do you still have the original drive? Do you mind creating a new clone drive again and repeat the procedure to recover the wallet.dat file? This time make sure to use other software to recover them and other tools to create a new clone copy of your disks like Acronis, ghost, or Clonezilla. I suggest burn a Hiren's BootCD or BartPE. It has many tools to use to clone and recover deleted files. |

Why don't you start editing your thread? Why keep consecutive posting? It's prohibited. You likely keep bumping your thread. Anyway, try to flash it back to stock firmware since you said that you already had experienced it before and solved your case after reverting it to stock firmware. If you had problem contacting Braiins support I'd suggest try to contact them on this thread below - https://bitcointalk.org/index.php?topic=5412808.0 |

If it's auto-tuning, then your miner is pushing the miner to consume more power to produce more hash rate. So it means it's overclocking, but the problem is if you are still using the stock s9 PSU, it can't provide enough power, which can lead to some issues like your issue.
So better manually set the power depending on what PSU you are using.

This is interesting. So I got the middle board identified as the error. the log is below.
I did do a hard reset this morning, and was still having the issue. I did it again after identifying the board and now now it works.
Error log with just the middle board running:
~snip~
What do you mean it works? Is the issue solved after a hard reset? Is all the hash board running? Or did you just run only two hash boards and remove the middle board? If the middle hash board is the culprit having over temp issue there might be one ASIC chip with a loose heatsink it needs to reattach but the problem you will need test fixture to test which chip is overheating. Anyway, if you want to repair it with your own there is a guide that you can follow but I'm sure it needs some repairing tools. Check this link below - https://www.zeusbtc.com/manuals/Antminer-S19-Hash-Board-Repair-Guide.asp |

I could't see which hashboard detect over temp would you mind to try to run the miner with one hashboard? I mean test them one by one disconnect the two hashboard power and data cable and test again to find what hashboard is broken.
Also, try to hard reset the unit by holding the IP report button for 5 seconds or more then release then test it again and check for changes.

The image shows a few software on your PC that use runtime broker, why not disable or uninstall those apps? If you can't able to remove the runtime broker try to disable it check the guide from this link below. - https://thegeekpage.com/how-to-disable-runtime-broker-to-fix-high-cpu-usage-on-windows-10/In addition, install Kaspersky and try to restrict/put runtime broker and other software to the blocked list. It also helps you to protect your PC from any malware and viruses. |

Did you tried to check the hashboard physically it should have something a name under ASIC chip like a100, a101, a102, and etc... And then from the logs start counting it to the right after that compare it to the count and the ASIC chip name.
This is how it works on other Avalon model so maybe a1246 is the same.

How hot the miner is it? Would you mind to post the API logs here maybe we can find the issue under your logs?
Setting the fan speed through the FMS tool is not permanent it will restore automatically to old settings after restart/reboot.
Sometimes the issue is hardware the temp sensor can't able to sense the temp from your hashboard. My suggestion is to try to replug all cables in your hashboard and also don't forget to check all terminals if there is rust or corrosion clean them then plug all cables in.
Another suggestion is you can also try aging it can calibrate all your hashboard which sometimes can fix issues related to temp sensing issues.

The price of miners these are pretty cheap from Bitmain and Canaan units. Why would you wait or predict the exact time to buy miners? Today is the best time to buy units from Canaan 1126 pro is around 400 to 500 which is cheap for 60 to 68th/s.
If today is not profitable to mine you can also hold these units until the price of Bitcoin gradually rises again.
So the best time to buy miners is when the price of their units drops a lot or is very cheap just like the units from Canaan.

stratum_subscribe timed out is most likely error from ccminer.
This is not the right place to ask this I'd suggest you to bring this issue to altcoin mining if your are mining with GPU/CPU.

Based on your image it looks like it's an airgap vault from airgap.it I'm also using that wallet. You need two devices to make your wallet safe you can also install it both on the same device the airgap wallet and the vault but it would be useless because the purpose of this wallet is to use it as an Airgap wallet.
The best thing about this wallet you can use metamask as your watch-only wallet and use only Airgap vault to sign a transaction.
The only downside is that they only support a few coins if you are looking for an air gap wallet that support many coins and token then a ledger or Trezor is your best option.

reading the whole tweet makes me think this is not a hack but it is stealing in disguise of a hack, they said the affected wallet was a cold wallet but a hacker was able to get the funds through a software. Doesn't make any sense and they dont keep it in a multi-sig wallet.
This is imppssible if someone could hack a cold wallet without internet connection. That is why they call it cold wallet or storage the device or PC should never connected to the internet. I guess this is another inside job just like what happen on other exchanges like in Poloniex or the same issue like in NiceHash. |

UTXO means unspent transaction output blockchair.com should have this data if you want to download them you can check this link below. - https://gz.blockchair.com/bitcoin/outputs/This is monthly seperated compared to loycev download links but you can use download manager like IDM to grab them all and download then extract them using winrar on the same folder. |

Do note that disconnecting storage option is only applicable on non-ARM MacBooks, M1/M2 MacBook storage is built-in into the board.
The logic board of these units is more likely the same as tablet or old android phone where the storage/drive are soldered on the board. But still the storage disk or IC can be still able replace but there is a big risk.
I'm going a bit off-topic here, but do Electrum and Core even work on the M1/2 macs? Considering that you can't salvage the hard disk if your logic board dies.
Since m1/m2 are macbooks Electrum and bitcoin core should work. If ever logic board dies you can still able to desolder the drive out from the logic board and move it to known working logic board but its pretty risky based on other people that I heard from tech forums. |

The reason why it's not yet in TradingView is due to liquidity I can't even find any pair for "MEX".
If your purpose is to use tradingview for analyzing the Coin or token then the exchange you use has its own tool just switch it to an advanced trading chart you can also switch it to the tradingview screen.
Don't access the MEXC exchange through the mobile version their trading tools will be vanished.

If you don't have a backup seed your last hope is to find the wallet file but if it's a tails OS I don't think you can still recover it using file recovery. Anyway, if it's not Tails OS then try to check these folders below Home folder > View > show hidden files > .var/app/org.electrum.electrum/.electrum/wallets.
Or
cd ~/.electrum/wallets Let's hope the wallet file still there. |

I am not sure whether its firmware issue or power supply issue as power supply is normal. Thanks.
I can't say if it's a firmware issue but it is more likely a PSU issue. Can you still access the WebGUI or dashboard? If you can still access through the miner's IP would you mind checking the API logs or any logs that contain your miner's activity logs? Maybe we can find the issue under that logs? Post the logs here don't forget to put it inside the code tag a # button you can find it while editing your post. Also, I would like you to try is to hard reset the miner by holding the IP or reset button for 15 to 20 seconds then release. Set up the miner again then test. |
