Thanks for the good wishes. I appreciate them.

I did not find the specific Computer Hardware section on Economy>Marketplace. I actually believe a moderator moved the thread already because it says Computer hardware at the end when checking the thread today. I sent one moderator a PM just in case, to double check.

I have taken a couple more photos with a sheet of paper, my username and the date; accordingly added to the OP.

Have 13x new Avalon Miner 741 @ 7.3 TH/s (1150W) in hand. The price of this offer is per unit, if bought one by one; otherwise a better price per unit can be discussed upon agreement with the buyer.

Each box contains the following items:

- AvalonMiner 741 - 1 piece
- AvalonMiner USB Converter 3 (AUC3) - 1 piece
- Micro USB Cable - 1 piece
- AUC3 I2C 5PIN Cable - 1 piece

I also possess 7x DPS-2400AB A PSU DPS-2400AB 2400w Platinum 94% 208v-240v. Each power supply can power up to 2 of these machines, therefore with 7 you can plug 14 machines to the grid and have some wattage left on one of the power supplies. If interested in the PSU along with the mining units, the bundle price can be potentially cheaper than buying a separate unit. Can find more informationg regarding this custom-made PSU here - https://bitcointalk.org/index.php?topic=1804048.0

They're in IL. USA. Can do cash, Cash App or crypto. They can be shipped domestically anywhere.

Hey there. I have an Antminer S9 13.5 TH/s. Recently we saw this famous Socket error, no connection. The miner was not working at all. We decided to look up on the Internet feasible solutions within our scope; found this YouTube video (https://www.youtube.com/watch?v=Dz2e76uixnI) that takes you through the upgrading process. In addition, tells you what files and what process you may follow. As in, we used such tool, fix upgrade and S9 all firmware update file. The problem being, it seems the update passes, yet we don't see any changes within the setup as the Bitmain manual states. (Attaching specific screenshots for better understanding.) The first chip does not have any temperature value, therefore we think it's dead. (?)

Used files:

- s9_fix_upgrade.tar
- Antminer-S9-all-201611290613-autofreq-user.tar

What do you think we should do at this point? We turned off the machine as the temperatures were heating up so much. Didn't want to mess it up. (More, huh.)

I noticed there's a newer firmware on Bitmain's website that * Update to UBI file system to fix the upgrade failure issue on some S9, yet warns you:

* Attention: do not use this fw on old S9 miners with fixed frequency. If miner works all right, the upgrade process with this fw is not recommended. Suggest : use BitmainMinerTool in Antminer toolkit to upgrade

Do you think we should follow the same process but this time with this newer tools? I'd highly appreciate if you give us some feedback. Thank you!
