yes, I do, I will present the results later

could you send me by email  pahtet2001@mail.ru as soon as possible to change the firmware so I really need my drone longer flies

tcchow.g.m Posted at 2015-7-10 17:42
so do u have any result yet?

I would like to present you the conclusions that I have so far and information of what in my case has changed as far as stability of the bird’s flight on different firmwares is concerned.
You probably know that the complete firmware includes different parts regarding certain modules in P3 (camera, radio, barometer, vps etc.). In the newest firmware version, DJI doesn’t always do update for all the modules. The software of some modules is the same as in the 1.18 version.
Personally, I had big changes in the flight stability  after the update to the 1.2.8 version, also having VPS switched off.  I was wondering why some people had the same problems I had and so many people didn’t have any at all.
I have done about 20 tests of downgrade and upgrade firmware in different order (only in the bird).
- Downgrade from the 1.2.8 version to 1.1.9 and then 1.1.8 through deleting parts of the software by using the bin service file.
- Update from the state after having deleted the parts of software as well as from firmware 1.18 to 1.1.9 and to 1.2.8.
I never had any problems with the security of flight using the software 1.1.8 and 1.1.9.
However, after some update from firmware 1.1.9 to 1.2.8 the flight sometimes completed without any problems and sometimes some issues occurred.
There were no problems at all when the bird was programmed to the 1.2.8 version just after clearing the previous software.

Many years ago, I was playing around with programming of the memory Eprom with bin files. I remember that the process didn’t always go correctly and that’s why in the past, in the end there was always done a comparative test checking if all the eprom sectors were saved properly (not only by checksum).
I don’t know if such test is being done after the update of the software DJI.

I have an impression that such test wasn’t done and maybe that’s why the result after update is not identical in all the users, and the correct programming happens always only in the clear version but not always with update. Maybe with the update sometimes something unchanged from the old firmware remains in some eprom sector. I know, many “maybe”.
In my case, I can use now the newest firmware 1.2.8 which I inserted after clearing the previous version – no issues so far. Of course I have done relatively few tests to be sure 100% about my conclusions.  However, at the moment, I am flying safely  on the newest firmware 1.2.8.

I would like you to pay attention to the fact that I’m not a professional programmer but I’m just doing it as hobby and I’m aware of the fact that I may not know something. Also, English isn’t my mother tongue so despite it, I hope that my explanation is clear to all of you.
Maybe someone here deals with the programming of the eprom memory and could help me to solve some doubts.

P.S. All the tests I did with 1.2.0 Pilot app because I hadn’t noticed any differences with the Pilot 1.1.1.

Do you know, it will work with Inspire 1?

Do not rely on the fact that you will send a fact file. I think robrogkr ordinary cheater and nothing he does not. He is constantly on the forum and nobody answers. The rest of the people who write that they have sent the file also deceive us. And it's all wrote the same scammer under different nicknames.

Thanx for XXXX Michael :-)

And I think that this log is the same deception. If it were not so robrogkr all I would give this file. So it is no one responded to requests for file and only now decided to write a few words. And where would he take such a file? the company DJI his statement regarded as cheating. All he is asked to give the file, and he just gave it to my favorites and the other users do not respond to their requests neither yes nor no.

Drop box it!!!!!

I was about to ignore this reply written in such form, but ok, I am going to write a few words to clarify it.

Each person who turned to me in order to receive the file, was sent a friend request. I wanted to give a bit more explanation on the topic to make sure that each person that was going to test this file would be aware of what such person was going to do.

These are my rules. I know that sooner or later there will be a person who will not be fair and as a result, the file will become generally available. But this is not going to be my fault. I'll see only, which way this file defeated, because each file has a different number.

Now, some words to you - exsellent402 :
I know that this is not your fault that you are expressing yourself in such way. I know your big and beautiful country with a lot of great person, I have been there three times and I have many friends there.
I also know that unfortunately there a lot of people think that each person is a liar and is trying to hide something. However, I can assure you that the world outside Russia is different, so chillout, turn off the TV with local news and you are going to see the reality :-) .
I sent you a friend request ( other friends can see it as well), you didn’t turn to me in a private message so I don’t understand your grievance.

PS. For all ppl who want to test the file. Please PM me on this. Please discuss here on the results of the tests only. Thanx.

Many THANKS to robrogkr for sending his file and downgrading my phantom to 1.1.9 !!!!!  Im ready to fly again after 1 month sitting and just looking my phantom. Thanks again .

P.S   I m a real person and not another account  of robrogkr like someone said.


THANKS BRO

I have a browser error when sending a personal message. I see that you have added me as a friend, but nonetheless ignored my request for a file. Other people gave you the file, and I inekotorym others not. As it is unfair. All phantoms and everyone wants to fly normally. If you have the opportunity - you can give this file to all who really need it. I understand you do not give me the file.

Robrogkr. I have a lot of problems with P3A and can not use P3A .. 20 days
could you send me the file to my mail?  
dangtrungyb@gmail.com
Pls
thanks ... pls

I try and successful... thanks RR very much (y)
tomorrow I will fly test too and will report back to you.
Again Thanks Bro (y) !!!

It was stated that not all of the components get updated during an upgrade. And some owners are not seeing any issues with their birds once the update is complete ... luckily I am one of those.
When I upgraded mine - I broke it. I interrupted the update process accidentally and had to take extra steps to get it back functional. I wonder if the P3 executes another routine when this happens and reloads the update completely or differently?

Would be interesting to hear how many of the users that boned the first update have issues after getting the bird back up and running.

Just some random thoughts.
