hi guys, I have. P3 pro and was advised to update the firmware. I did this without any issue on the quad, followed instructions on the controller. Placed card reader in USB slot, powered up and waited for the red light to turn blue.. It never did, it was just solid red and then after about five mins, the controller has switched off. I haven't taken the card reader out or switched the controller back on... ny ideas on what I should do? I hope I haven't cocked up the controller which willneed to be sent back now...! Any help appreciated..! Thanks very much in advance..
