I ordered some new Block Erupter Blades off Amazon. One of them came without any firmware.
Having worked with PICs for some time, this was easy to verify.
I also tried to copy the code from a working unit but read protect is enabled.
The seller has not responded to any of my requests to return the blade.
I know it’s not much but I will offer a 0.1BTC tip to anyone who can provide firmware to get this hashing.
