Guys, I am getting the same issues, but after a lot of testing the current situation is this:
P4 Firmware version 01.02.0602
RC Firmware 1.8.0
App Version 4.0.3 (Go4)
Ok, what happened.
1. About 5 or 6 weeks ago, Firmware upgrade to version 01.02.0602, appeared to stall part way through, left it to finish, battery then flashed the centre two lights (updating battery firmware), that battery has been dodgy ever since.
It shows "Battery damaged" shortly after take off, and no longer displays battery info. If landed and rebooted sometimes its ok again, but cannot be trusted. I have two other batteries all of which came in a kit on Christmas eve so just 2 months old. Those other batteries are so far absolutely fine. Had a couple of minor glitches but otherwise has been flown 4 to 6 times a week for a good 5 weeks.
2. Recently a prompt showing firmware update popped up, let it do it's usual update and then getting a disconnect intermittently ever since.
On boot up currently the P4 takes about 5 to 10 mins to finish several fan spin ups with the SD/Connection light flashing either green or "red red, green green"
The Go 4 app will show that my quad is a P3 Pro until the final fan spin up which then runs constantly, and if it actually finishes the SD/Connection light turns constant green. (doesn't always finish and needs a couple more power cycles)
If I then restart Go4 it will connect, not always and doesn't always give the video signal. If I don't use my tab or phone and just the RC to connect and try a basic flight, it will not connect to the RC unless the SD/Conn light has turned constant green. And with the P4 doing this fan spin up and down for 5 to 10 mins that indicates to me a FIRMWARE issue.
3. Intermittantly I get "No SD Card" error, "Latest Firmware Abnormal" and "Aircraft Encoder Error (0x800020)"
4. After loads of testing over this weekend, I have discounted SD cards as an issue by using several different cards including one from a fully functional P4.
I have also confirmed EXACTLY the same errors appeared when using a Samsung TAB S2 8 (Noting other posts stating could be a usb com port issue requiring a setting tweak in developer mode), well, as I said, EXACTLY the same issues on my LG G5, and a pals Ipad Mini 4 that he uses with his P4
5. Today I tried recalibrating the IMU's, on finishing and resulting reboot, the Go4 app connected very quickly so something happened to the positive, then a prompt appeared that firmware was not consistent and the little slider button appeared, I slid it to the right to accept and the blue flashing banner to the left showed "Updating Phantom 4 01.02.0602"....well hang on a minute that's what it already is!!!???.......so let that finish, and restarted, all good and fully functional...........until the next restart.
6. Now it wants to do the firmware update again, and will not connect...so exactly the same.
7. Have already "restored to factory defaults" using the Assistant 2", and also note there is no longer an option to roll back to a previous firmware version, the only one listed is "..0602"
So currently have a "bricked" P4 and 1 out of 3 batteries in an unstrustworthy condition.
My thoughts from an IT perspective is that either there is some dodgy code in the firmware, or my quad and maybe others out there have a fried or otherwise compromised firmware chip.
Last weekend I was flying a rescue mission within 3 meters forward and behind in a reveen 60 meters below take off point off a cliff and over the sea.......this weekend it wont even get out of the house!!! |
