I think if your wallet is set to pruned mode and you use -reindex it will only download the latest blockchain and delete old blockchain you recently downloaded.

I don't know what would be the outcome after you use the command above but better add prune=(N) at bitcoin.conf file so that it won't download the whole blockchain.

Can you post the whole debug.log here and don't forget to put it inside the "insert code tag" with icon #.

I think the reason why you get this error it's because you have corrupted blockchains.
I'd like to suggest is to try manually reindexing the wallet through the terminal.

Use this command below


Let see if it will work.

What do you plan why you are looking for these miners?
Do you have this miner and looking for a way to flash it?

This miner is not common and only a few people have this miner. Why not try to go on cheetah-miner.com it seems that is their official website.
Or if you are looking for the firmware to flash this miner they have a firmware here https://www.cheetah-miner.com/Pc/#/download

The broker you talking about is a company? Or just a person?

How did you know that he is SEC and FINRA active?

I never had any experience dealing with a Broker but it seems suspicious to me if he asks for a 15% commission before they send your ROI because he can just able to deduct the commission in your ROI.

How many times did you replace those chips?

Would you mind to tell us the exact model of the chip or the chip type? Maybe the ASIC chip you are trying to put on the s17+ hashboard has a compatibility issue?

I remember someone that blame me before he was invested a big amount in BTC and built a miner when the price reach the highest ATH last 2017 I think.

But the price keeps crashing after the new ATH, I thought that the price would increase more at that time but I'm wrong. That is why they blame me because they never earn a profit even just reach the return of investment and end up selling the miner and BTC at low prices.

So right now I never tell anyone or sometimes I tell but I always tell them to invest only that you can afford to lose.

If you know the exact model of the PSU you can try to search it on ZeusBTC use the link below and type the PSU model or just PSU.

I tried to search on Amazon and aliexpress I saw only a few of them but no trust ratings yet. So I think this would be hard if you are looking for a PSU for this unit.
Try to ask him for a PSU unit model and try to search on Google if you can find a site that sells it post it here and we will check if you can trust that site or not. Beware there are lots of phishing sites or scam sites that sell any mining-related products.

There are lots of news before about blockchain but we don't know how these people protect their own wallet on blockchain.
I have an account there and open it with my backup from blockchain.info to .com but my Bitcoin is there.

So, what I think is those people who lose Bitcoin on that wallet are being phished or it could be some hacker stole their Bitcoin because Bitcoins, before is not yet known by any Antivirus or maybe those who lost bitcoin have infected PC that it could possibly the reason why their Bitcoins are stolen.

Right now, I never use them again because that wallet is online and there is no guaranteed safe there are many things that could happen if your wallet is always online and hackers can do anything they want to brute force your blockchain wallet.

If you don't have Bitcoins before on Blockchain why bother? You can just switch to other wallets like ledger or trezor or Electrum.
But if you have Bitcoins before and now it's gone then why not try to report them to SEC if you have evidence that you can report?

What tools currently you are using to detect those faulty chips?

Have you tried to flash it first to known working hex file? If not try it first.

There is a guide on zeusBTC that might be able to help you check this link below.

Actually, I never trust anyone giving only a telegram group link and most of the scammers use that app.
So there is no guaranteed that your signal will work because most of any telegram groups are giving you false signals they just make a signal for their own benefits.

Sample like you tell them to make take a position today at this unknown coin might be shitcoin or anything coins that you can easily to manipulate.
You will tell them to buy at $1 as a sample but you already bought a large amount of that unknown coin after you give a signal those who follow you will buy that may help that coin to increase in value. After that, you have the opportunity to sell yours to make a profit before you tell or give a signal to your followers.

That's an easy manipulation, right?
And most of what I see they also use telegram to gather many people as you like for spamming or use them to sell the telegram group after you reach enough members in your group. This is very common which is why there are lots of people being scammed by following any untrusted group and people on telegram. Those scammers can able to run and no one care actually if you have been scammed because no one could track them.

The only thing that I notice are abnormal signals no hashboard and no fan on the logs on that image in your first post.

And Yeah it could be a PSU issue but would you try to tell him to reset the miner to factory default.

I got a guide from their documentation about this miner below


Then tell him to test it again.

If it does not solve the issue try to tell him to flash it again with the latest firmware and reconnect all fans hope this one will work.

They have but the problem is you can't sell neteller funds instead you will receive the payment through Neteller if you sold crypto on Binance p2p.
Look at the image below as my screenshot found it there on p2p payment settings.


That's the only option that I saw on their app but if you change your local FIAT to USD you have the option to find the Neteller sellers but the problem is the current rate is pretty high it's around $67k.

What I think is if he doesn't want to exchange the Neteller funds at that rate his best option is to buy USDT instead of bitcoin.
Look:


The best thing is it's zero fee.

I suggest try them all and test them one by one.

Post the kernel logs here and let us analyze them again for you.

We don't know actually what cause this issue but if you have an extra miner with the same model unit it would be easy to troubleshoot the issue.

What I think is the PSU is failing or not giving enough power to run all hashboard properly but it could be also the control board.
Can you check the miner physically if there is some button like IPreport button or reset button? I just want you to try to reset the control board by holding those buttons for 15 seconds and check the miner if it reset the miner to the factory settings and then tests it again.

Have you also tried to contact poolin and maybe it's just a firmware issue and poolin might send you a firmware that could fix this issue?

Why not use other tools or switch to other trackers instead for calculating your taxes?

I heard someone before with false tax calculations on that app. So maybe switching to other tools like cointracker might be able to help you.

Also, I suggest you check this thread "[Tutorial] Crypto taxes for beginners" for another options and guides to calculate your taxes.

Never heard about this miner before it seems that this miner has 4 hashboard and according to the logs there is a problem in the 4th hashbord that keeps showing that error.

Can you try to disconnect the 4th hashbord and try to run the miner without it?
Or try the remove the first hashboard. Let see if it will mine properly without that error.

If not, check the kernel logs again if there are changes on the logs.

If you always get those errors related to the wallet file format then the wallet.dat file might be corrupted.
You tried almost all possible tools to recover that wallet but I'd like to suggest that better to get help from a professional recovery service.

You can try to contact them here http://walletrecoveryservices.com/
Or go to their official thread here https://bitcointalk.org/index.php?topic=240779.0

How did you end up using this wallet?

It seems the pro version of Aladdin wallet is never mentioned here on the forum.
According to them, the email is enough to change device or password.
Look at the image


So I think you didn't understand what support told you, they said if you lose access to either email or phone number you will also lose your account. It means without the phone number you can still able to recover your account with your email or without email you can still be able to recover your wallet with your phone number.

Why not follow the above suggestion under device change or you can directly go to this domain below

Why not clean it and replace a new SD card slot you can find them on old phones or gadgets with SD card slot or buy SD card slot to any online shop, I couldn't recommend ZeusBTC because the minimum amount of orders is 10 and the price is around $1.39 each.
Here's the link if you still want to buy from them https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=1130

But if you want only 1 slot you can buy it on Amazon, eBay or aliexpress.

Or if you don't want to spend then you can try directly jumpering the sd card with loaded firmware already to the control board.

Also found this thread below and maybe it can also help to flash your s9 directly through RX, TX, and ground.

Usually for fan intake is on the front of the miner and the exhaust is in the back of the miner according to your error it's an exhaust fan. It gives you no RPM/speed signal.
A miner fan usually has 4 wires

black = ground,
red = Voltage input,
yellow = PWN controller,
blue = RPM/speed signal

So the blue wire might have no connection if you have a multimeter you can check the wire(Without this blue wire it always running at full speed). Resoldering or replacing the wire might solve your issue or completely replace the fan. If it doesn't solve your issue then the culprit is on your control board the socket might have been full of corrosion or rust replacing the fan socket or cleaning it with petrol or lacquer flo thinner might solve this issue.


The hashbord error is related to the chip and maybe it's a program issue on that chip. According to microbt error description logs you need to contact a technician for this error.
About what parts or which hashboard is the slot0 it should be on the left side(Hashbord) not the middle or the right side hashboard.
