Hi.
Up until today I had a perfectly working P3 adv.
THis morning when I decided to update the firmware to the newly realeased 1.8.8 it all went wrong.
First time I tried the update it went on for about 4-5 minutes, then stopped...
I tried redoing the update severeal times (I think 10 times by now.), all with different combinations of SD cards, remote on/off. and lots of other combinations.
The P3 is all dead now. If I turn it on it beeps two short beeps, pause then two shot beeps..and this goes on, the wing LEDS dont flash. BB--BB--BB--BB
If I open the GO app it says that firmware is up to date which i doubt looking at the log file, but it also cant display battery level anymore. Says "cant connect to flightbattery".
The motors wont start either.

Any help appreciated?

The logs look like this...
Packet: P3S_FW_V01.08.0080.bin
Result: Failed.
Reboot the aircraft and try to upgrade the firmware again.

Sorry to hear that. I'm searching for a solution because I as well am experiencing almost the same exact problem. Working perfectly before I attempted this update. I've never had this problem in the past with any of the other firmware updates only this "P3S_FW_V01.08.0080". Good luck and if and when I find the solution for my problem I'll be sure to come back and let you know.

    Cheers, Greg

Thank you Greg, havent found a solution yet, but I'll post here for sure if I do!!

If you have any other flying app installed on your mobile device...ie. Litchi..etc. uninstall them.  Reboot the mobile app, RC then aircraft. If you haven't upgraded the DJI go app to 2.7.2 start with that upgrade first. What are the latest upgrade versions show in the go app for go app, RC and aircraft?

I had problems with the upgrade. After I uninstalled the Litchi app from my mobile device, I was able to complete the upgrade.
