    Phantom 4 Pro V2.0 crashed mid-flight

    Thanks for the addition! I will store this hint for further analysis of logs. I like these tools very much!

    Phantom 4 Pro V2.0 crashed mid-flight

    Went even further and found another flight with this battery on the same day 16 november 2022. The log shows that after the drone takes off the voltage drops to 12V almost instantly. I plotted the height graph too and it shows rapid descent (maybe a crash too). Then the drone reports the...

    Phantom 4 Pro V2.0 crashed mid-flight

    Moved forward with the analysis of the logs. I checked 10 logs before the flight and only one flight with the same battery was on 16 november 2022. I think it was just a motor test as the flight data is very short (50s), no GPS, Ultrasonic sensor height 0, and the capacity percent remained 63%...

    Phantom 4 Pro V2.0 crashed mid-flight

    Do you see in the log if that happened? Is there an official info about this somewhere? Definitely interesting theory.

    Phantom 4 Pro V2.0 crashed mid-flight

    Thanks for the comments, yes, I was not the pilot. I also think that taking off with 40% battery calls for catastrophy. However it would be strange that the drone lost power mid-air but dropped with its battery still in place and turned on. Maybe some power fluctuation that restarted the FC? In...

    Phantom 4 Pro V2.0 crashed mid-flight

    Yes, that would be strange for me too. But as you can see the end of the log is missing. I am unsure how much time is missing from the end...

    Phantom 4 Pro V2.0 crashed mid-flight

    Thenk you @Meta4 for your assistance! I don't have the txt log yet (I suppose I should get it from the RC, I will try tomorrow). In the meantime I uploaded the DAT to Wetransfer and here is the link for it: FLY188.DAT I found this strange graph in CsvView: PPMSned and PPMRecv graph is moving...

    Phantom 4 Pro V2.0 crashed mid-flight

    Actually I couldn't attach the DAT file as it was too big. SO I exported a csv, I hope it will fit. Tell me if it doesn't containg everything needed.

    Phantom 4 Pro V2.0 crashed mid-flight

    Hello Everyone, I am trying to find out the exact cause of a sudden fall mid-flight. This was not my drone. I repair drones since 2016 (1000+ repaired drone) and I have some experience in analyzing log files with csvview and airdata but I think I can learn more. I cannot find any clue in the...

    No image transmission signal - P3P

    So after many tries I think I am stuck. I replaced the OFDM module 2 times with known good modules - no solution. I replaced the OFDM - GIMBAL ribbon cable with another one - no solution. I even replaced the camera module and the gimbal flex module - no solution. GetFPGAstatus err...

    No image transmission signal - P3P

    I reflashed the NAND with the primary kernel image, you can see my log here. However still the same error occurs when I start the drone. https://pastebin.pl/view/c22fb2ea Any other ideas? I still cannot access USB to reflash everything from there.

    No image transmission signal - P3P

    Thank you @quaddamage, I missed that! I will take a second shot about it today and I will report back on my progress! Thanks!

    No image transmission signal - P3P

    Hi Everyone! I need a good piece of advice, let me explain. I am new to this forum but I am not new to this scene. (I am repairing drones since 2016, I repaired more than 1000 drones successfully.) I also repaired several P3P gimbal boards with fw extraction and reflashing before these tools...
