Hello, on my Phantom I got an error message (IMU calibration needed). So I calibrated the IMU. Then I took it out for a flight. But I had to wait for a while because it said "Aircraft Warming Up". Then finally I could start, first in Atti Mode (because no GPS next to my house), then later it...

It looks like there are multiple layers of security going on. They are using efuses and disable debuging after the factory mode is switched off. Currently the biggest change is to somehow modify the file start_dji_system.sh Here they start a FTP server which we can possibly use to overwrite...

If its not designed into the firmware by dji, then forget it. No way. Probably they use a different fpga and entirely differnt hardware. The Phantom 4 is still very fragmented hardware with many boards, so I guess they went ahead integrating things more and more. Easier to roll your own firmware...

If any of you is in IT (embedded systems, binary analysis,...) it would probably be helpful to have a look at my thread about reverse engineering the firmware. I already found multiple single weakest spots, where one breakthrough will compromise the whole security chain. check...

Can anyone here find something useful? Where is the handler for the four telnet ports? And for the serial interface?

Guys, I dont want to do this all alone. Are any computer scientists here? Dont you also want a shell into your Phantom? How awesome would that be. Does anyone know anything? I had a little time yesterday. Used binwalk to descramble the latest P4 software update that is hidden in the DJI...

I found an Serial interface on the board of the P4. Does anyone know the baud rate, stop bits and things?

Does anyone know anything about those telnet ports? Or some secret FTP account? Maybe some other direct acces to the linus file system. Any infos about those internal SD cards? Or hardeare serial ports? Does anyone know something about the encryption used? Cant be that hard after all. I...

Didnt work for me. I tried this some time ago when I saw this on Youtube. Does it work for you? Did you try?

I don't think so. - The bird can be flown without connecting a smartphone. - There are also other apps using the sdk like Litchi. - The sdk reference on DJIs website doesn't mention such a feature. - In some other place I red that the Drones GPS location on startup is used. - Even if its set by...

Hi, I got a phantom 4 broken off ebay and repaired it (broken voltage reg). I have been flying which is fun, but its annoying, that the link breaks down after 1000m-2500m and that I cant go higher than 500m (I live in the alps and want to go up mountains, always relatively close to ground, but...
