Downgrading firmware on P3P from 1.10.9 to 1.7.6

Hello friends.
I went to lower and lower firmware (P3P) but after uploading 1.7 of 1.8 there are problems. Gimbal does not react, the message about the problem with the firmware makes it impossible to do anything. I had to go back to 1.8. Some solution ? Regards

and do you have gimbal problems with FW 1.8?
if not, why do you want to downgrade?
And why everyone here wants to lower the version to 1.7 ?
(There is no problem in version 1.8) Regards
this thread is quite old and some of the information is not true anymoreAnd why everyone here wants to lower the version to 1.7 ?
if you want to mod the flight parameters of your AC, there is no need to downgrade
for a few months now with dji-firmware-tools you can modify any Phantom's FW
and what did you want to use after downgrading to 1.7.60?
it's still the same tools, except the fact that one year ago it was called phantom-firmware-tools and now it's dji-firmware-tools
AFAIK there is no FCC mod for Phantoms, 32 channel hack only
removing altitude limit is possible of course
There is no FCC mod for Phantom 3 Pro/Adv. There is a hack for Ph3 Std for a long time, and there are app modifications to enable FCC for Ph4s. Though for whether the hacks really work - I only seen Ph3 Std tested with power meter.
Changing P3P from CE to FCC. Is it possible?
This thread is about downgrading.
Also, figuring out the software by yourself is more educational.
You need to extract firmware, edit flyc_param_infos and update them within flight controller module. Then flash that to your drone.
Try searching for retroroms dji wiki for details. Also there's nolimitdronez which lets you pay for having such things done automatically.
I won't mind if the thread will be cleaned of these unrelated posts.
Hello, my example China, I can't find the firmware of remote control 1.5.8. Who can send it to me, thank you. My mailbox is [email protected]
I can't stand the fact of dji crippling 'my property' even more with every supposed 'better/newer firmware', and while nothing wrong with my AC nor RC, I had a new droid device and couldn't immediately find my saved copy of the older app so installed the new. OF COURSE then, and only after then, the newer app gave me the new firmware required message. I refused to do it, BUT, afterwards trying to fly without updating, I was getting ESC error and couldn't power up the motors app or not. After reading this Entire Thread First, I got my drone back to Great and Even Better!
Even after all of this time, and even though there's also now the newer(cool way to do to, but not for any lamers that can't/don't want to study/read whole threads and directions) of downgrading the firmware's, I'd like to shout out a Super Kudos to the original poster of this thread for his method does indeed still work just fine as I downgraded to 1.7 easily, as well, like he, I hit the bump in from 1.8 to 1.7, though flashed 1.8 back and again 1.7 and Whalla! Success! Later this week, I will edit a flyc_param_infos, re-pack/compile it to the .bin, flash and test my pro out again this weekend with my 8 batteries. Thanks again to the original poster and others of whom led me to find the answers!

What I mention is very similar, Newer because a lot of it is recently Updated(files) And, COOL because also allows learning of personally modifying parameters directly to the firmware and then popping in the bin on the SD card and flashing.
It's first mentioned about on Page 1 of this thread by the original author, phantom-firmware-tools github project page. There is also another page by maybe the same author of the project link?, that lists his actual downgrade of FW steps, and then explains the phantom-firmware git page files and steps to modify some things(a LOT of things), at http://dji.retroroms.info/howto/modp3params. ''I didn't use the later to do my downgrades'', I used page 1 on this forum, RC v1.5, AC 1.7.
hi have the same problem constant beep at the end let it go for a half hour longer still constant beep gave up
Hey, I've been chatting to Steve via email but still cant solve my issue. He has provided me with the modded PMCAPPFw3.bin file but the hight restrictions didnt work on 1.11 fw. So, we're trying to downgrade to 1.10 fw. Sounds simple... right. Nah... two days later, still can't get it to work. I put a debug file on the sd with 1.10 and it went through the process for 25 min then the card says 'upgrading...' however the app says 1.10.90.
Hight still locked. Any ideas!? Thanks! Its a P3P btw.

Hey, did the log pass/fail text file say 'upgrading...' after you did this or did it say 'sucessfull'?
