Hello all. Long time user but have never posted.
I recently bought 6 A4+ from alibaba. I knew it was a risk but I got them at a good price. I got videos of the miners hashing at 630+ for each one before shipping. I am using 220 volt power supplies each being 1000 watts or more. The first thing I did was update the firmware on each machine. I immediately noticed that hash boards were missing on the overview page of some of the miners. I did not check the hash boards before updating firmware. Some miners had hash boards present that eventually went away. I went from 4 hash boards initially being down to now 8. I've tried using previous bin files to change firmware on miners which brought back 2 hash boards. Now I am down 6 boards. Two of the miners only accept swu files so I cannot go backwards on the firmware on those miners. Does anyone have a previous swu firmware file to try?
I am hoping to get advice from you guys for a process to go through to diagnose these hash boards to see if they are actually dead or if they can be revived. My supplier has video proof that they worked before shipping and is offering to send me more hash boards for free. I want to keep this guy's trust though so I want to try everything I can before taking him up on this offer. Any help would be appreciated.

I have a very similar problem but with a A4+ LTC master. How did u flash the bin Firmware? My A4+ has an alternative control board that doesn´t have a TF card slot and the web interface only accept SWU files.
If you get the firmware please let me know, i been looking around for a while now
I have 2 of the LTC masters I suppose. I ordered 6 A4+ and 4 of them are the normal web interface and use .bin firmware updates but two of them have very different web interfaces and only accept .swu files for firmware updates. The web interface for the LTC master is cleaner and you can tell it is more modern but I cannot find older firmwares to try to get the hash boards to be recognized. I may end up connecting the hashboards and fans from the LTC master into one of my A4+ control boards. My supplier is sending me 6 hashboards to replace the ones that are not working. I was able to get two of them to come back online by flashing the A4+ to an older firmware.
On one of the LTC masters, it shows 4 hash boards and only one is hashing. The other 3 say "alive" next to them but have no hashrate. I don't know what to do with that but will try connecting them to an A4+ with an older firmware to see what happens.
