Can anyone tell me where to find the previous firmware for the P4P+ RC?
The AC is easy to do via Assistant 2 but RC needs to be done via the SD card and I am unable to find the firmware.
I did a test flight and some filming last night. The thing was dreadful, strong interference, weak signal, poor video. If these things aren't right that what other problems are there? It worries me that it will do something completely random and drop out of the sky at great expense or cause physical harm.

It is not a firmware update to the RC, that is a software update and can not be rolled back without re-installing the app. Unfortunately on the P4P+ you do not have that option.

I may be wrong about this and someone from DJI might correct me but I've yet to hear of anyone going back to an earlier version of the software on the P4P+. All the other P4P all you have to do is reinstall the ap on your tablet or phone but the device on the P4P+ does not allow you that option as far as I know.

A case of Plus standing for less then. Maybe they should have called it the Phantom 4 -
Thanks for the reply

Have you tried to reset the Remote Controller to factory default? If yes, how is it going?  If it is still the same , please PM me your email address and more details about this issue, I'll look into it.

I'm in the same boat. Any idea how to reset Remote Controller to factory default?

Yes. Just downgrade to previous version using assistant 2 for your AC then go into settings on your RC and you will find factory settings re set.
It works ok, better than the latest firmware but still far from perfect. I did a test flight tonight and felt safer like this.

I've reset mine to factory default and still the same issues (Just made another post). Strong Interference, Constant Wifi Warning messages when I don't even have a phone near it, etc. I have the exact same issues and a factory reset does not fix them. DJI needs to do something here and we need to let them know it's not just one or two of us.

Try setting transmission to 5.8. Do it in custom settings as leaving it in auto doesn't seem to work as it just reverts back to 2.4 and then keeps giving poor signal warnings. Yes DJI does need to know but do they care?

Thanks. I did the downgrade of AC and than factory reset of RC.  However the RC firmware is still v 1.2.0.0 and there is  no downgrade option for RC's firmware in RC's settings. I did few short test and it seems RC and AC can work together.

Do u have the maps worked perfectly at your country? Some ppl said only china.

Updated film of Phantom and my RC to latent. Maps where only China. Reset of RC turend out wel. Stil just lost of warnigs about interference but flying works wel to rangen over 1250m.

Yes, I tested my P4P+ and have maps for my country, Croatia, Europe and for the moment AC firmware is V1.03.0509 and RC is V.1.2.0.0.  For me it's not clear is this combo approved by DJI?

I downgraded my AC from V1.04.0602 to  V1.03.0509 and did factory default reset of RC because:

1. After upgrade with  V1.04.0602 I got a lot of strange warnings some of them were about Wi-Fi and 2.4Ghz,  
2. I got the warning to upgrade my no fly zone database. I tried to do this few times but without success, during upgrade some wrong IP address was reported despite I have been on internet and did all other upgrades without problems.   

So it seems the users of P4P+ can downgrade the AC firmware only and the users of P4P can do it on both AC and RC. I guess it should be fixed for P4P+ users.
In the mean time I have changed my user name from fans27f43bcd to mzmg. Has no idea why Estonia is reported as my country!? My country is Croatia.

This seems to be a link that was provided on a different Forum. It is a previous update for the P4P+ controller i.e-:GL300E.

Could be worth a try to achieve a downgrade.

Thanks a lot, hope I will be able to downgrade my RC too!

I tested AC firmware V1.03.0509 and RC  V.1.2.0.0 combo and it doesn't work for me (false warnings like: conflicting with 2.4GHz despite I set 5GHz only, all the time strong interference - fly with caution, firmware upgrade required etc). So as I got the download link  above I will try to downgrade my RC too. Hope the old firmware will fix the issues.

I tried. No success! After downgrade my RC with v1130 during power up I got the message on the screen: Unfortunately, DJI GO 4 has stopped. No way to start RC any more .

OMG I'm in Russian Federation now!

I resolved it. With the small buttons at the edge of the screen I got the system settings window and started factory reset including clearing all SD data. After that DJI GO 4 works well and downgrade (v1.1.3.0) step is done  for my RC . It seems I have all as before............. Uh

I had that conflict with 2.4 and turned out be be my wifi was on.  Swipe down and turn off your wifi.  Not needed.  That is where your conflict is.
