I'm having trouble updating my MFC firmware to 2.15 using Windows 7 on a laptop via MIDI-OX and USB->MIDI interface. I got "ERROR 10" (Flash Write Failed) several times and noticed it was happening at about the same place. I thought perhaps the Axe Fx was chattering at the thing and the comm interrupts were messing with the timing, so I undid the CAT5 connection and switched to the stand-alone power supply so there'd be no external interference. Same problem. So, I started reducing the size of the buffers and slowing down the packet delay, to no avail. At 82% (consistently), I get "ERROR 10". I'm down to 64 byte buffers with 192ms delay between and it still tilts.
I could try using the Axe FX as the interface, but everything seems to be working fine as it is until it gets to 82% complete, so I don't think the interface is the problem.
Anybody else encounter this, or have any advice?
