Hi All

If you are a mac user like me there was no program to downgrade your bricked P4 (I had to borrow a PC laptop), well I just found this on youtube i have downloaded it run the program but not flashed my P4 firmware as i've already done it, but it looks good in case of future problems.

It's a possible solution but :
- Do you know the creator of this program? Are you sure that the owner doesn't inject additional code in the firmware upload process?
- As you said, it can brick your P4,
- Can break warranty,
- If your drone crashed and cause injuries to someone of to structure, your insurance (if they analyse your drone, of course) can say : you play, you loose! And you pay cash.

So the risk is high, we must wait the FW or try other "official" solutions.  I know !  ;-)

D U M L d o r e is a better alternative to downgrading. Google without spaces.

Mine was out or warranty had it over a year, and was completely unflyable after the update. It was more liable to crash and hurt someone after the update it flipped itself upside down and crashed into bushes for no reason in sport mode, so had nothing to lose downgrading, but now have my P4 flying like it did before the upgrade. So a safer drone and DJI more liable to put dodgy code in than drone enthusiasts who are trying to help other drone users

I don't understand the philosophy of DJI with this kind of issue, 2 months without any informations/news, it's not correct at all. So we took the necessary solutions to leave the grounded situation. So if we choose an official solution or third-party solution, it's the same for me, we want all to solve this issue.  So blaming DJI continuously without doing anything, it's like viewing a person hit by a heart attack without doing the necessary actions.  ;-)

Yep...same here. Flys like it did before the update. I would still like to be on a current version though so hopefully DJI will help us out.

It's DJI's responsibility. They NEED to fix this.

Yes it's correct. I have installed the last FW several times, each times I had different behaviours!
So Now, I have no error messages and I'll want to test deeper my P4. Due to weather condition and KP Index (8), I cannot test probably this w-e.  I want to be fixed. So I think that at the end of September, we will have a fix.

Susan,

There are hundreds of people who can't fly the p4 who is basically bricked by dji through faulty firmware. I make a bed the good admins here have already a list with the complainers  just for the case to block them.
Why you do not send this  what you have to those people. Off course it will be in the risk of dji and not of the client by law, because all firmware must be made for save use.
I guess after all the weeks dji let the clients wait without an official sorry, the new firmware should be done soon.
I gave my case already to a law firm to deal with.
