Harper86 and Cryptonica helped me out getting a backup of the A3 firmware. thanks for that guys! Cool

As others already found out as well: The A3 and D3 are very similar. I even found out that the software inside the controller chips on the hashing boards is exactly the same.
Out of curiosity I tried to run the A3 firmware on the D3 and the A3 firmware actually detects the ASIC chips and tries to start mining on the D3 hardware. Looking at the logging it's fine, but it doesn't accept the work as Bitmain did actually changed something on the ASIC chips I guess. I do think they used the D3 as a base and stripped out 10 of x11 algorithms.

For now the conclusion is that you can't convert the D3 to an A3.
It probably does need reprogramming of the ASIC chips on the hashing boards itself.

Blissz please help us out with the A3 FW image you already have. Me and Tssar have the same problem (2 out of 3 hash boards not showing up). I tried everything, PSU, cables, turn on/off boards one by one, Factory reset, nothing helps. Before I open a ticket with Bitmain, Id like to try reflashing the FW as a last resort. That way I succeeded in revitalizing a D3 with similar hash boards issues a few weeks ago! On Bitmains support page there is no trace of A3 reference, manuals or files Sad

Keep up the good work mate!

I had this similar issue with a S(, Unplugged the white controller cables, then plug them back in, on both ends, and the hash board that was not lit up, started to work.. Power off of course
