P4Pro firmware issues

I have tried getting the NFZ patch to work with firmware 01.05.0600, but the drone refuses to ignore the NFZ.  I have gotten an email from NLDronez saying that the startup order is important, that it needs to go Remote>Drone>App.  Browsing the forums, I saw that it is recommended to go Drone>Remote>App.  Which one is correct?  I downgraded to 1.02.0203, and it works with that firmware, but I eventually had the limp gimbal issue and it freaked me out.  I tried to re-flash 1.02.0203, but it didn't fix it.  I had to flash 1.05.0600, then go back down to 1.02.0203.  Does 01.02.0304 fix the gimbal issue?  Lastly, even when running 1.05.0600, none of my DJI Custom Unlocks will import to the bird.  Is this because of an inherent difference in the NLD firmware?

The device must be in airplane mode.
Follow the order, turn on remote then drone and last launch NLD app.

Hi

I have the same problem, please guide me more fully. Thanks

Hi. Is there anyone who can tell me what I should do next? I tried to install the firmware for my Phantom 4. It got 95% done and it sat there for about an hour so I restarted my computer and tried again. Now it's telling me that it's failing to upgrade no matter which firmware I select...what should I do now?
