RE my post #53, the youtube member removed the video because it wasn't 100%, There are other videos like it though. The idea is, you boot up the RE, wait until it boots, then boot up the AC, wait until it boots, then connect manually to your mobile device Phantom Wifi, then load the flight app, and it might bring you FPV.
This worked for my + for a while, but then it stopped working.
@Mark The Droner, thanks for summarizing the "quick fixes" and "sure fixes" for the people on this thread. Also, thanks for referencing the little tutorial that I put together - credit where credit is due, the real geniuses were Gaucho, andrew_by, and rmhome on the PhantomPilots.com "lightbridge firmware PROBLEM (and solution) - firmware version not found by dji assistant tool" thread.
Below is a little more background and a few more tips that I've put together over the years. I hope this helps P2VP fans get back in the air one way or another!
What about heat? Heat never helps! But it's not the root cause. It probably increases the rate of volatile memory corruption, but even a cool module, sitting on the shelf, corrupts over time - as we see from the myriad hobbyists who turn it on after shelving it for 6 months only to find FPV isn't working.
Now you have telemetry (because the top board in the wifi module still works and transmits wifi signal to the range extender), but the FPV doesn't work because the Davinci video processing chip on the lower board stops doing its job and freezes during its boot-up sequence.
What are your options (as of March 2019):- Buy a working module ($100 to $200 on eBay) that is working for now, but has a non-zero chance of failing in the future
- If you live in the USA and you've never opened or modified your drone, try your luck at DJI's P2 Care Plan - maybe after filling out the survey and jumping through all the hoops you'll get your drone fixed for FREE!
- Get a newer drone that is less likely to go blind: Mavic Pro, P3 Standard, Phantom 4, etc. (note that some P3Pro do go blind for similar reasons to the P2VP issue)
- Reflash the NAND yourself, using the tutorial I've put together - this requires about $30 of equipment and a steady soldering hand. Be careful not to damage the test pads on the board or repair will become impossible for you or anyone you send the board to!
- Have someone else repair your board for you (~$80) - I am in the USA and do the repairs (contact me here), in the UK/Europ the https://www.youtube.com/channel/UCSzKC4DjDV7zS7FuRm5t8JA has a tutorial on the fix and does great work, or try one of the handful of people offering the service on eBay (my handle on eBay is okstuv)
Oh, and one more tip. For those of you with no telemery and no fpv: your problem is Binding, not necessarily a bad module. Unfortunately, binding the module to the range extender is trickier than it used to be. You see many modern cell phones are not completely compatible with the binding feature in the DJI Vision app. I've put together this tips and tricks page to help people bind their range extenders properly - even examples of what a bad bind looks like and what a good one looks like. Enjoy!
Good luck and happy flying!
