Hey need help downgrading firmware back to 3.12 from 3.14, I have been having major battery issues since firmware upgrade. I also have seen others trying to go back because of issues as well.  I have tried door, test, 125 but it always says password is wrong. I have submitted a ticket to dji but unless you own a P3 or inspire they do not respond.

Please help, I a almost ready to just buy a used p2v+ just for the old firmware. So sad

The downloads page for your model should have the previous version of the assistant.
On my V+ it does anyway.

You cannot downgrade the firmware. The Phantom Assistant will always give you the latest version.

You can get the previous version of the assistant with the version you want you will have to do a hard reset to load the previous version. Not for the faint of heart. There are YouTube video on hard reset and reloading the firmware. Not really recommended but durable.

Make sure you delete the original APP from your computer and download the right version of the APP you want from the download page for your version of Phantom before you do the hard reset..

Gerry, when you do this, will PT2 have the previous firmware with it or will it still need to check the DJI servers for the latest firmware? I'm asking because as Mike said, PT2 only shows the latest firmware, nothing to choose from. Cheers.

OK. I've tried downloading then installing 3.6 last week but it still showed FW 3.14 while connected to the internet. I'll try it again, sans internet. Cheers.

Fella's,

My bird is still on 3.12. Is there any way I can help? Can I somehow "download" my firmware? Just trying to help. I see this is a big issue on many boards.

that would be awesome if we can figure that out but we need someone that is good with the software side, not me.

I tried the hard reset, then running assistant 3.6 on a fresh PC (never seen dji on it before) hard reset super easy, used a jumper from a old hard drive worked great. when I connected to assistant without internet is says no updates. I was hoping that since it said that the firmware was 3.08 on the site that it was packaged with it. No luck. as soon as i connected to internet it downloaded 3.14 again. back to square one

Hi PB, I'm in the same boat as you are so I really want to see you succeed.

Question - without connecting to the Internet, PT2 version 3.6 says no update, but did it report any firmware version or it showed only dashes  -- -- -- -- --?

Hey folks,...just my .02....The DJI site appears to be  a "forced loader" for lack of a better explanation....and as soon as you connect to the Internet it will download the latest version regardless of what you think or want which really sucks as when you turn on your ie. iPhone and there is an update for the iPhone, it at least advises you that there is an upgrade and you have the option to update it or not....
For this reason, I disabled my internet on the laptop I use for the Phantom following my 3.12 upgrade and have not connected it to the Internet since or will not...I could give you the 3.12 on a Dropbox but it will require the Internet to download the firmware which will give you the 3.14...pretty sure the only way you will get 3.12 is to go back in time or to buy a bird with 3.12 in it!...anyone with a Delaurian please let me know!

I think if we can find 2.12 cached on someones computer we could at least trick the system, I don't care it it thinks I have 3.14 but loads 3.12

also it does download the new version but it doesn't force to to flash, that was me being dumb and not waiting

If you hard reset your Phantom you are basically erasing its brain! Then you need to reload the new Firmware...
As far as affecting the RC, I have not seen the video which is earlier on in this thread, I would watch that and see if he mentions it.
Thinking it through, if you are hard resetting your Phantom you are not doing anything to the RC in that procedure..just the Phantom though you may need to rebind them, not sure about the RC version and compatibility with the Phantoms version from that point forward..but the Phantom hard reset will not physically change anything on the RC.
