apm 2.5 mavlink issues

hi all.

i have been using an apm2.5 running 3.2hexa firmware. i have tried uploading 3.15 on the board. it said firmware uploaded but not verified.

then when i am now trying to connect to mavlink, (it shows the arduinomega2560 and also comport10, by the way), it says no hearbeat packets received, nor am i able to upload new firmware as it says, "error message-no communication"

i have tried uninstalling the comport, changing its baud rate to 115200 but in vain.

any suggestions would be grealty appreciated
