Would it possible post a copy of the RCS file for RC zipped, as need a copy. As I couldn't recover my RC I only recovered my drone.

Can u tell hiw to fix. 4k
I try and stuck. And try to solder on wifi and not loading. When solder the wifi. U connect all cable or just power to make it on.
Plzz help
Sent from my SM-N9005 using PhantomPilots mobile app
Can you please reupload the rcS file, it said there is no file to download.
Thank you
Hi, Bro.
Thanks to you, my rc works (have a vacation in Bali, I'll buy you a coffee
). I tried to recover the drone and I deleted ^M already, but the drone still cannot bind with rc. I also tried to bound the drone with the new rc, cannot bind. Any clue?I cannot download it. Would you please or anybody else re-upload the file? Really appreciate that.
Thank you
I connected power and gimbal. The sensor panel was to fiddly to connect so i did not connect it. As it appears you dont have to connect it.
Hi all,, i think i bricked my drone.. RC is working fine, connecting and i can move the gimbal. but no wifi connection and i can not FTP/Telnet on drone. RC is fine.. Any solutions ??
I did try to upgrade on 1.6.8 but it beeps continuesly after starting to upgrade its like Deeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee....... all the time.
Tryed waiting about 1 hour,, and also tryed 1.5.7 force downgrade,, and same.. Formated sd card, tryed another,, nothing works..

I came across funny problem while fixing bricked bird, I connected to bird and pressed ESC to cancel autoboot. Ran setenv and bootm, the bird normally completed boot process, enabling wifi and connected to RC. By this time DJI GO recognized my P3S, video came back, and the system was back to normal.
However, I turned off and turned on bird's power, then I let it complete boot process automatically, but it came across the error "/etc/init.d/rcS Not found" then it locked in loop "/dev/ttyS0 not found" and it got back to the state before the fix has done.
It is interesting, because /etc/init.d/rcS is intact, I overwritten normal bird's file on it, no carriage return (^M), file is on mode 775 and is executable. Moreover, when I boot it manually with bootm command, it normally brings wifi up and shows telnet prompt. I don't know the difference of those two boot methods, but I have no idea now. Please advise me if you know about it.
Thank you.

I did range mod from Phantom 3 Standard range mod , let's do it together... and now my drone's RC doesn't create Wi-Fi access point. This topic is for those unfortunates who've done the same and don't know how to fix it. So please share your situation and ideas.
I used mac, filezilla and vim to change files. I defenitely forgot to do "chmod +x" which is thought to be crucial.
Today I brought my drone to the official repair service here in Moscow and I'm waiting now for their diagnosis, it should take up to 5 days thay said. It seemed that they have no special instruments for reuploading healthy firmware to RC and drone using service connectors or smth, but who knows..
UPDATE:
With common effort, the way to recover has been discovered. Basically, all you need is to connect to TX, RX, GND pins of Wi-Fi module board with UART TTL adapter and open serial console(see pictures here I bricked my p3s with ftp range mod - let's fix it together and here I bricked my p3s with ftp range mod - let's fix it together). Then you should prevent u-boot from loading linux kernel by pressing ESC key and type to u-boot console the next commands(thanks ElMalo):

And then
ar7240> bootm 0x9f420000
This will allow you to boot backup copy of system. After that you'll be able to mount main root filesystem:
mkdir /tmp/flash
And then mount it:
mount -t jffs2 mtd3 /tmp/flash
Then you can go to /tmp/flash/etc/init.d folder and repair the rcS.
In order to recover drone you should repeat all the steps but connect UART to gimbal's board. Here are the pictures of pins you need to connect with your UART adapter.
Thanks everyone who participated in the research!
Hi,
Thanks to everyone here, I can recover the wifi signal both rc and phantom. But sadly I still can't bind rc with phantom. My question, are the rcS file both in the rc and the drone the same? Or maybe there are a slightly differences between them? I just re write the content of all the rcS files (rcS, rcS_ap, rcS_aphand, rcS_cli) in the phantom same with rc. Would you please or anyone here upload the original rcS files from the phantom? I've got the original rcS files of the rc from Killabear.
Thank you very much

If you had read the earlier pages in this thread, you would have seen the command that restores a working copy of the rcS file from the device itself. Read back a bit and I'm sure you'll find it
You have to change UART TTL adapter to another one. That is only way.
I got my RC and quad fixed today. Here is how it went down in putty window:
