Yes, it's recommended to buy directly from the manufacturer or authorized distributor you will most likely scam if you deal to unknown resellers.

you can also try to contact this man offordscott he is the one that I know trusted selling miner.
Or try to check this website https://www.zeusbtc.com/Used-ASIC-Miner/

Did you replug the cables and the issue occur?

would you mind to try running one hashboard with a known working cable so that we can check if it just a cable issue if not then try to upgrade your firmware to the latest version. Sometimes it can fix this problem by upgrading it to the latest firmware also, check the miner hashboard physically, and maybe a few of the heatsink is loose.

I think it will not work because the S9se have different control board if your purpose is to unlock it try to flash it with a k5 image recovery through an SD card.
Check them here https://service.bitmain.com/support/download?product=Flashing%20SD%20card%20with%20image

Then you can start flashing it with different OS like HiveOS or Awesomeminer.

Are you sure that your Raspi has an internet connection? try to reattach the cable if it is connected through the ethernet cable.

Also, try to replace the pool server or other servers I suggest try this pool below

- https://solo.ckpool.org/


I still do not work bring your issue on their official thread here https://bitcointalk.org/index.php?topic=5053833.0
Then ask for help.

I suggest do a firmware upgrade first before you do anything else about hardware.

If the upgrade doesn't work try flashing it through the SD card and if it still does not work then go try to replug all cables including the PSU metal(reattached the metal) and maybe there is a connection problem between them and replug the ribbon cable and clean other terminals with thinner or isopropyl alcohol.

How did you end up using this exchange?
This is what happens to those people who are eagerly want to exchange coins or tokens.

I hope next time do some research first or ask here if the exchange is legit or not to avoid scam. The ranking and trust score on Coingecko is useless you must ask or do research before you decide to deposit.

Try to use incognito mode when accessing and configuring your miner.

Also, try to manually type the pool server then save it. If it doesn't work you might have a miner with locked firmware.

Based on rankings BUSD is a much higher volume than DAI and the bad thing about DAI is you will pay a high gas fee compared to BUSD.
Also, BUSD has more liquidity than DAI.

So for me, I choose BUSD but the only problem is yes it's centralized, unlike DAI. As of now, I don't see any issue with using BUSD unless you want to hold them for a long time but if you are planning to hold it for a long time then DAI would be the best but take note of gas fees in the future and stable coins are not good to hold for long term or as a store of value, unlike other coins.

Why not read the sticky thread instead to know which wallets are closed source and open source?

You can find the sticky thread under this section or go directly here https://bitcointalk.org/index.php?topic=1631151.0

Take note most of the wallets are closed and only a few wallets are open source like Bitcoin Core, Electrum, and Wasabi wallet.

Double-check your Bitcoin core Armory won't work if you running Bitcoin core at pruned mode you can find it under settings and uncheck the prune or you can edit bitcoin.conf and add prune=0 if you don't have bitcoin.conf you can create and add that line.

Also check the troubleshooting guide here below for Armory wallet

Would you mind to try to reset the unit to factory default?
To reset the miner to factory default look for "func" button and hold it for 5 to 15 seconds then release then check it again.

If still doesn't work and you can still access the unit through the browser try to copy the Cgminer API logs and paste it here make sure you use Code Tag to make your post clean or paste the logs in pastebin.com and paste the link here.

Never heard that someone can make s9se to add more hashboard in one controller maybe you can only succeed if you have a custom or modded firmware but I can't find any modded firmware yet unless someone here can provide it for you.

Try to contact this man thierry4wd
he is always looking for a tester from his custom firmware and maybe he can help you mod the s9se firmware.

Also, check the Coinbase card they do support Canada.

And I think Binance also offers the same thing you can check this link below.

What exactly is the unit model of your ASIC machine?

There are ASIC miners that only mine at 200v to 240v less or more than that could damage any components in your miner mostly PSU due to overheating.
I suggest you try to use software to auto-shutdown the miner like awesomeminer to reduce the risk or to avoid burnt PSU or hashboard.

Be careful on using any mining app for Android they are mostly stealing data from your device and most of the mining apps on mobile are partnered with Honeygain and peer2profit.
Those sites are apps where you can earn by sharing bandwidth this is not safe because they sell the bandwidth to other people and it is possible they can remotely access your device or use your bandwidth for illegal activities and be arrested by authorities.

If you actually want to mine Bitcoin or other coins then you should buy an ASIC machine or build a miner to mine Bitcoin/altcoins.
I suggest you read this thread below

Since you are Jr.member you should be aware of the search button(Magnifying glass) that you can find in the upper right of this screen?

Here are some of the threads that you can find if you research a bit the same as your topic as a newbie.

I know how hard to explain it to other people who don't know about Bitcoin I have experience telling some of my friends before but they told me that Bitcoin is a scam even I have already withdrawn Bitcoin many times before except on scam Bitcoin cloud mining and investment site.

It seems the source where he downloaded the Electrum is not from the official website I found 4.1.5-2 in Github user Archlinux

Here's are the sources

---

@2647s

It's not recommended to download Electrum from other sources you should only download Electrum on their official website electrum.org

We already have guides on how to verify Electrum you can check these links below.

- How to verify Electrum signature video guide
- How to check if your Electrum Wallet is legit before using it. (For Linux)
- How to verify your Electrum [Windows, Linux, Mac]

It's a bit outdated so you need to replace the links with the latest version before you verify.

I don't see any difference between the old s9 hashboard compared to your hashboard.

You might be just purchased a used miner with a recon(repaired) hashboard.


Those parts are the most common issue like a shorted so possible that part in your hashboard disconnects all connections and replaces a new small board to bypass power or to fix the shorted part.

I tried to search but there is no modified firmware that you can use to overclock the miner.

However, I found Hiveos they have special firmware that you can use to flash your miner with built-in HiveOS client.

You can find it here https://github.com/minershive/hiveos-asic
