Im not.so luky like you. My.ps3 have low 5.8 signal from one of two bird leg dipole.

I am boosted.. Kinakailangan ang Pagtiyak sa Seguridad

Does anyone have problems out of new firmware update??

Many people have no issues and love them and there's also a handful of people like me where FW made them practically useless.

frenky600 · May 6, 2017

When i bought my second hand p3s i spent a lot of time to learn about short 40mt range on 5.8 rc signal. My friend gave me a field meter from 1 to 10ghz. After many test i know that the power on bird side was on first leg dipole 15dbm and 2dbm on second leg the rc was perfect at 17 dbm. Afert changing cable and antennas on bird nothing goes better. This problem affect also the signal strenght on bird rotation.

I keep getting a strong interference signal and after like 400 feet says lost signal I have the ARGyek wifi & signal range extender kit with 3 flat panels and 3 Omnis long antennas and worked great got at least 4 times range but since firmware update all missed up I could possibly have a wire come off or loose but before I break it open again just wondering if anyone else has this problem

5000ft = 1500m. is very big distance with stock config.

Hello, my name is Juanma and I am new to the forum, I have a P3S, the problem I have is that the video signal I miss very much
Very close, I'm trying to follow the steps to download the firmware but I can not go from 1.7.9, since when I try to continue with 1.7.9 with the debug I get on the screen of the app that is 1.8.1 to update . I'm pretty desperate because having this dron and not being able to push it away more than 50 meters because losing the signal is frustrating, I tried with the station of another partner that has it with amplifiers and I still have the same problem, this friend of mine has in his dron Firmware 1.5.7 and today has taken it to his to 6 kms and without a problem. Thank you and I hope your help.

Revised P3s Debug downgrade
How to...
Never skip a version
Always run the firmware first (pass or fail)
then run that same firmware again with the Debug file also...
Then format the card and run the next lower Firmware
then again with the Debug file and so on..
If you get sensor errors follow the steps below to fix them..
If you have v1.08.10 with a +
Then start here
v1.08.10 -> v1.08.10 + Debug
v1.08.10 -> v1.07.9
v1.07.9 -> v1.07.9 + Debug
(v1.07.9 -> v1.7.94 If you get "Sensor Error" if not skip this step...) I am waiting for clear info on the next step from here for further downgrade..
v1.05.7 -> v1.05.7 + Debug
v1.05.7 -> V1.5.75 If you get "Sensor Error" if not skip this step...) I am waiting for clear info on the next step from here for further downgrade..
and So on.. Here is a list..
v1.0.14
v1.0.17
v1.0.2
v1.01.3
v1.02.4
v1.03.5
v1.04.6
v1.05.7
v1.5.75
v1.06.8
v1.07.8
v1.07.9
v1.7.94
v1.08.10
There are new and older Firmware Versions not listed...
Anyone Know them?
Without exact firmware numbers
Links are hard to find..
1.7.94 link
P3C_FW_V01.07.0094.bin
1.5.57 link
P3C_FW_V01.05.0075.bin
The rest listed are here

after v1.05.7 to V1.5.75 Firmware bin file is corrupted, download it again from the DJI offical website.

I installed 1.2.4 FW but had compass errors over and over and then all of a sudden, somehow, the calibration took. So no more compass error but now the controller won't link. I pressed the reset link button on the AC for a few seconds, then turned the wheel on RC to the left and toggled S2 3 times. I could see they both turn green for a second, and at the same time the app shows a green signal for only a second, then it's back to red and unlinked. What the mother FK!! Gonna throw this thing in the **** garbage lol. I have now been trying to relink RC to AC for half hour....no luck. Ugh!!!

Some news for your downgrade test? After reading many post seems the problem for many bird still upgrade from1.2.4
I don't want to believe our bird was fried due to update.

Use this method.. (If the gimbal light is blinking green and red) it is working

NEVER stop a F/W process!!! wait for 1 -3 minutes after the light goes solid red or green... (debug does weird things) If you use my method the app will say it is done.. I would debug 1.5.7..

KennethMcNutt · May 20, 2017

This many be the Fix for the Compass errors in 1.5.7 for some...
Remember Downgrade to 1.5.7 and then Debug 1.5.7 the update to 1.574..
Possible update to 1.5.75 after...
P3C_FW_V01.05.0074.bin

Could someone please tell me where the debug file is located and whether or not I actually need to use it? I have tried putting the next lower firmware on my sd card, but it does not transfer to the a/c. I am assuming I need to debug... please correct me if I am wrong

Well, my how to is in the first few posts.. http://www.phantompilots.com/thread...med-working-update-sensor-error-fixed.108575/
Papa Tita has helped me with this video also.. Thanks, Papa!

ARGtek followed suit... Thanks, Nelson!

This is mine... Please read my full description

Ok, so lots of people appear to have successfully downgrade FW from 1.8.n down to 1.5.n Of those, how many actually saw an improvement. Everything I read was that no one seem to get (back) an improved range. If thats true then why bother???

This is a very good question!!!
The answer is...
For me... I wanted everyone to be able to find out for themselves..

But there are other reasons that people do it also

Jake_The_Snake · May 29, 2017

I saw some improvement with my P3S in distance and the RC signal reliability

Benke Smith · May 29, 2017

So to clear some confusion, please confirm this is the right order (assuming you start from 1.8.10):

1.8.10 => 1.8.10 + DEBUG
1.8.10 => 1.7.90
1.7.90 => 1.7.90 + DEBUG
1.7.90 => 1.7.94
1.7.94 => 1.6.80
1.6.80 => 1.6.80 + DEBUG
1.6.80 => 1.5.70
1.5.70 => 1.5.70 + DEBUG
1.5.70 => 1.5.74
1.5.74 => 1.5.75

I did all the above until 1.5.70 + DEBUG, but then tried 1.5.75 (did not know about 1.5.74 at that time).
Tomorrow I will try to do 1.5.70 => 1.5.74 and then 1.5.74 => 1.5.75, and will post the results here.
