avrdude: verification error, first mismatch at byte 0x0178
0x3d != 0x3c
avrdude: verification error; content mismatch

I'm trying to program a custom built pcb called Bitponics (kickstarter project that flopped after launch) with an ATMEGA2560V-8AU chip. It has FTDI Pins and ICSP header. It was suggested on the Arduino forum to use Nick Gammon's bootloader on it since I couldn't get anything uploaded, so I used my Uno to upload the new bootloader but now I'm getting this verification error. What should I try next? Thanks for your help!
