I replied to another thread where someone had a similar issue - but in case that one gets lost - here is my story.
I received my new Mavic 2 Pro around the end of November 2018.
For the first 4 weeks I have had nothing but smooth flying and have had zero incidents or issues and have used utmost caution when handling/shipping/flying my new expensive toy.
Fast forward four weeks - Suddenly, upon turning on the AC and the Remote, the AC would show flickering yellow leds on the hind legs (indicating that it's trying to connect/connection failure). The remote would stay in a "connecting..." state. Both units were fully charged and had flown succesfully two days earlier. My phone (Galaxy S7) could succesfully connect to the RC, but the RC and AC (aircraft) just didn't connect anymore.
I figured for some reason perhaps the two became unlinked so i proceeded to try and "re-link" (re-bind) them.
Now i'm no stranger to quadcopters/controllers/receivers and flight controllers - I've built a dozen or so FPV racers with various receivers and flight controllers and have done my fair bit of troubleshooting - so binding a drone/receiver to a RC is relatively straightforward to me - and in this case the instructions were clear - get the RC in the binding state by either using the button sequence, or by using the app. This i could do using both methods - and the RC would start with it's constant beeping and show the appropriate "binding" text.
My problem, however, was this:
Whenever i pressed the little bind button on the AC, the red bind light (which is supposed to light up) did not do so. It's like I just couldn't get the AC to go into Link/Bind mode. I tried holding it in, tried pressing firmly, lightly, multiple times - nothing worked...
Eventually i resorted to various firmware upgrades / downgrades figuring that maybe something on the mavic's firmware could cause the craft to not enter bind mode. (I've had multiple successful flights using 01.00.0200 prior to the sudden connection problems between the AC and RC and i have never had to re-link the AC/RC since they arrived linked when I received them). I attempted the firmware upgrades/downgrades using the DJI Assistant App on my Windows 10 desktop - using the app wasn't an option anymore, since the RC and AC could not connect.
Just like in the thread above i struggled for hours to get the firmware installations to complete - and when i eventually did, i still had the no-binding-light and just-connecting issue as described above.
Eventually i returned to the retailer where i purchased the Mavic - a very reputable local high-end camera dealership who are also official DJI suppliers. The guy in the shop basically did exactly what i tried, but with no luck (could not bind and could not update firmware/downgrade firmware or reset to factory settings).
They sent it away to the regional head office - and i have been informed that they too have not been able to get the two units to bind - and that they are now shipping the Mavic/RC and Battery to DJI China.
Now I live on the other side of the world (Cape Town, South Africa), and sending something to China and back takes upwards of 6 weeks (and is really expensive even by international standards).
They also took the liberty to inform me that should DJI decide to charge me for any "repairs" that i would be provided with a quote - and if I decide to decline the quote, i would be liable for the expensive shipping. All this for a product that failed 28 days after purchase.
What makes everything even worse is that my wife and I have an upcoming trip to the Philippines - we leave around mid-March. I purchased the Mavic mostly with this trip in mind - giving me a few months to get used to it before traveling and using it around the islands.
I am extremely disappointed with my purchase - the lack in local technical expertise/really bad after-sales support and the reliability of the unit itself.
Also - around here things are a bit more expensive due to taxes and all kinds of other rediculous reasons - so I dropped the equivalent of $1800USD on what is now essentially a useless paperwieght on its way to China.
I am quite sure I will never purchase another DJI product again.
