The 12-word seed phrase from trustwallet is BIP39 which means you can able to import it to other wallets that support BIP39 like Electrum.
But the problem trust wallet supports multiple cryptocurrencies so you can only recover Bitcoin unless other crypto wallets support BIP39.

Pretty bad you have 19 missing characters from your WIF key it takes years decades before you can able to recover it and there is no maximum number of missing characters that you can recover 1 to 3 missing characters can be easily recoverable but above 3 it takes a few months or years.

Why not try to recover it there is an easy tool to use for recovering base58 encoded strings such as WIF keys.

This is not a complete logs I guess and I think you already reach the character limit.  I suggest use pastebin.com to paste the whole logs of your miner and share the URL here.

Have you tried to do the basic guide from Bitmain? Try to follow the guide below if it didn't work it might temp sensor issue.  I also one you to try run miner only one hashboard and test them one by one and then post the changes here.

Actually, there is still another way to install the latest version of Mycelium by faking your current version to the latest version. But it's a bit risky because you will need to jailbroken your phone with cydia and install mycelium .ipa outside appstore. Just like android if you install malware your data is risky.
For those who don't know you can jailbreak new or old IOS version using ch3ckrain.

I agree there is no bad and good suggestion but in the basics of repairing units, you should always start with software before hardware.

And only if he has BGA hot air to reflow those ASIC chips but I think hair blower would also work to melt a bit cold solder joint but not for long term.

There are few of them here in my area at first they said they would help people to make money fast and invest related to Bitcoin but in the end, after you pay the entrance fee you can now join their seminar and the seminar is almost related to trading and nothing else. It is almost all basic trading and a guide on having a Bitcoin wallet which the guide can easily find on the internet.

The only thing that I noticed is that why would they say fast without telling people that trading is risky or Bitcoin is risky?
I don't agree with most of what they said about Bitcoin without warning people about the risk.

And another thing is there is some seminar that leads you to crypto investment with instant profit which is a scam but still people believe they will make money by investing in such a scheme. Many ignorant people don't know anything about crypto yet and mostly are senior people who end up investing with a big amount and believe they will make a big money instantly.

Your issue seems related to ASIC chips your miner's hashboard might have a defective/broken one that leads your miner to stop mining.

Would you mind to try to flash your miner through an SD card and upgrade it to the latest version do this first before you follow the suggestion above(Sometimes touching any hardware could cause another issue or might get worst).

If you don't know how to flash it through SD Card you can follow this "17 series TF card flashing guide"

There's no safest exchange all of them are risky if you are planning to hold coins for a long period of time.  
Why would you transfer your coins from a hardware wallet which is way more secured and have full control of your wallet?

That's pretty bad practice if you don't want to lose in a bear market when coins are dropping then it is better to use virtual Bitcoin on PayPal for safety but the only problem is Bitcoin/other cryptos on Paypal can't be able to transfer to another wallet. However, the advantage is that you can able to exchange your Crypto back to fiat instantly. Since Paypal is a big finance company and it was here for many years Paypal is safe but the problem you don't actually holding a real Crypto.

I believe this is because of your iPhone IOS version because the apple AppStore won't allow you to download the latest version of the Mycelium since your ios version is not compatible with their latest one. It only allows you to install the last Compatible version with your current IOS version.

Updating your IOS and updating the mycelium again should fix this issue however if you are using iPhone 6 below they no longer have any updates their last version is IOS 12.5.5. iPhone 6s and above support the latest IOS version which is iOS 15.6.

So it's because of version compatibility version.
I have a suggestion mycelium is pretty problematic I'd like to suggest switching to another wallet like edge which is way better than the mycelium wallet.

If you are using the Nicehash Bitcoin address you don't have full control of your wallet same as Coinbase. As the above said it is not safe to use those wallets because they are online wallets, unlike non-custodial wallets.

If you want a secured one I suggest you check Electrum so that you have full control of your wallet you can follow the guide here [GUIDE] How to Safely Download and Verify Electrum [Guide]

The best thing is that it also has an EMV chip for data protection or antitheft and most what I like are these 3

- No annual fee
- No foreign transaction fees
- No exchange fees to acquire your rewards.

It seems that I like to have this card to avoid fees.


I don't think it is only for the US according to them Gemini master card is available in 60+ countries worldwide I'm not sure I can't find it on the credit card page that they only support the US. But it seems they also offer it to other countries if you are qualified because of this button below



I tried to registered today the only problem I'm stuck at the home address where the next button is grayed out.

Actually, the forum is the only best source of learning if you just know how to search you can find them.

Anyway, there are lots of sources like the other posts above but if you are looking for a big source to learn about blockchain and Bitcoin including crypto I have two links.
Check these two links below I'm sure you can also learn how to build your own blockchain or if you don't plan to be a developer there are some courses there that will help you understand how Bitcoin works and also other Crypto.

Well it is a trial and error if you don't know what exactly the firmware installed before you can start flashing it with the 2nd one which is this ANTMINER-S19-release-202111161922.bmu
If you have some issue experience then repeat the procedure flash it again with recovery and then flash it with the first one "ANTMINER-S19-merge-release-20211216091201-8IN1.bmu"
Then test it again.

That's the only problem it seems he doesn't have Bitcoin address stake there or even other threads.
Most of his posted addresses are ETH unless if he can prove that he owns this address: 0x0B4B0867f86a16002Fe5a4Db770B3EE35FAfD86A
Which is posted around 2018.

If you already have the BTC address from your wallet then you can check the balance to any block explorer like blockchair.com but if not yet there is another option opening armory without syncing the database which is the offline version. Check below as a reference



Click the offline one and then open your wallet and look for your addresses. Check them one by one in Blockchair.com to check the balances.

Have you tried to check if the Armory wallet is actually pointing to the right path for your Bitcoin core and blocks?

If not then try my suggestion below just leave the database blank but don't forget to manually put the path for your Bitcoin core/bitcoind

I think you can only fix it if you have your own full node or ElectrumX server where you can able to edit the minimum relay fee because most of the nodes or servers listed on Electrum only have a relay fee of 1 sat/vbyte lower than that I think no server offers lower than the current minimum fee but you can try to find server under "green circle" change your server and try to send.
Or your last hope is to have an ElectrumX server where you can able to edit the minimum relay fee.

There is someone here on the forum who created a thread about his wallet all funds are automatically sent to another wallet every time he deposits any amount.
Which I think is related to this maybe the one who created a thread recently is a victim of this scheme.
Here's the thread I'm talking about https://bitcointalk.org/index.php?topic=5406545.0

Hackers might be using other user's accounts and spread them and later use a node with a bot script to automatically send all funds received from that wallet.
The only way to counter this is that also make a node and run a bot to automatically send it to your own wallet must be faster than the hacker's bot but the problem is I can't find a script on Github. I have a link before but it was deleted.

Currently, there is no other SD card firmware for s19 they only have one image even on BraiinsOS, ASIC.to, and Awesomeminer they do have SD card firmware but it won't flash directly to the nand.

How about flashing it two times?

And what exactly is the issue you currently experience?

If the firmware from Bitmain does no solve your case you can use other firmware available from what I mentioned above it won't flash to nand but it will boot directly from your SD card. So you need to keep the SD card plugged.

Or try to contact Bitmain and maybe they do have another SD card image that can totally clear the Nand program.

Currently, no one yet sharing a repair manual for this unit.
If you want to learn how to repair them maybe this link below will give you some idea of how to repair the A1246 hashboard.

Why not discuss here what exactly your miner issue is?
