I'm trying to update the firmware on one of my 3dr radios and it works fine on one however on the other it just says "Upload failed SYNC lost". I'm running the 3DRRadio Config 0.8.
Any ideas? As it's the copter side radio i've got it connected using a ftdi friend from adafruit

Fixed it - turns out it was related to another issue I was having, http://diydrones.com/forum/topics/upload-succeeded-but-verify-faile...
The problem was I had a 4G USB dongle connected to my laptop with an a powered extension cable, i'm guessing it must have been causing issues on the USB ports because as soon as i disconnected that i was able to connect fine and also I had no dramas updating the firmware on the 3dr radio.
Tried it with a 5V TTL logic levels and i still get the same result.
Does anyone know of a way to get it out of bootloader mode so I can at least use it with the old firmware or is it completely bricked now?
Just realised i have a 3.3v ttl ftdi cable, what are the logic levels of the 3dr radio?
I can't even see the settings it's configured for as when i press Load settings it comes back with "failed to enter command mode".
Maybe i have a dodgy radio?
