Factory Reset, Update: It fixed my altitude problems!

AsiaFlyer · Jun 19, 2016

My P4 has the altitude problem really bad, tired of waiting for a FW fix.

Has anyone done a factory reset successfully? I don't have much faith in DJI and don't want to end up with a brick.

There is no way to do a "factory reset".

Yes there is Mike, in the latest version of DJI assistant

Full reset (factory reset)

Why not give it a shot then, Phil? Per the thread you linked, it sounds like DJI support is saying you won't hurt anything by doing it.

Worried it has not been tested enough and will brick my P4, don't have much faith in DJI at the moment

A factory reset wouldn't "brick" your phantom. The terminology of "brick" or "bricking" comes from when you update a firmware and it fails to properly load/install it.

A reset would reset all the settings but there is no reason why it would cause issues. But ensure you calibrate all sensors, IMU, compass, collision avoidance, VPS, etc afterwards.

Let's hope so, going to try it now, will report back

Make sure you calibrate the vision sensors.

How did you go?

I did it a few times several minutes ago and am charging now for a flight. We will see how it goes.

It worked!!

I did a factory reset in DJI Assistant, my P4 is like a different craft, within seconds of taking off I could tell it was much more stable.

Not once has DJI support or any of their forum support guys ever suggested doing a factory reset to fix it.

(Still not great flying over my swimming pool but that's to be expected with the VPS on)

Have just completed another sensor calibration and if that doesn't fix the yoyo issue I will try that as well as my P4 yoyo's very badly! Up to 10 metres and makes getting usable video very difficult.

Exaxtly the problem I had, tried all other fixes (multiple sensor calibrations, IMU calibrations, lowerered my gains), this is the only one that worked

Did you calibrate the sensors as per the video I sent? How did it go? easy? hard?

Done it lot's of times previously trying to fix the altitude problem, with the updated version of DJI assistant it is very easy

When you did the factory reset, did you have to re-activate and name your aircraft again?

no i didn't

Didn't work for me unfortunately.
Returned my P4 for repair yesterday.
I expect I'll get it back by Christmas next year or when the P5 is released. Not a happy camper right now.
