Please don't shoot the messenger, here are the options I believe you have.
1. Purchase a replacement PCB board from another source in China or on the internet
2. Rig up a method to run each blade as a usb miner with a control board
3. Sell the pieces to someone on this board that may need the parts and recoup some of your coin.

If shipping broken units back is not working out, it might make more sense to see if there is a trusted member here who could do the repairs nearby (same country would be good). This is what was done with Drillbit boards that needed some repairs. Drillbit paid for the repairs in that case. I don't know if BTMine will offer to do this but it would go a long way in terms of building some trust back.
id prefer not to waste any more time with this junk and invalidate my paypal claim. the way btmine chooses to communicate also fills me with no confidence of this ever working out.
I don't know how everyone's came, but mine wasn't even repairable. One of the units was completely unsecured and had broken part of the PCB in shipping...So I can't just desolder and solder something back on.
Soo....what's the recourse for people who don't want to pay $400 to ship something back and then have it refused to be signed for?
