Iam on 1.4 firmware so if I put 1.3 on my sd card and put it in the phantom will it just downgrade my firmware ?. I seem to recall the text file saying your firmware on the phantom is newer then the one on the sd card. So it would not downgrade.
Cheers.. So you went back to 1.3 on the bird to upgrade battery then back to 1.4, I have a new battery that needs the 1.3 firmware so it looks like I need to go back to 1.3 on the bird to update the new battery then go back to 1.4. What a mess about just to update a battery.Kind of weird for me. Wife bought me a new battery the other day. I know the new firmware did not have any battery upgrade, so I put the 1.3 on the card. Installed new battery, turned on phantom. Took 20mins to upgrade. but it downgraded. So, after going 1.4 back on the sd card, it took a few mins and it upgraded.
