Hi, I updated my firmware after I noticed a notification in the app about firmware V2.7.47 is available. Everything went correct until the screen with upgraded components appeared on my remote controller. Device asked for rebooting RC and aircraft. I did it, on the screen appeared powering up and then connecting but from this time the RC has never connected with aircraft (but it still can send a video from camera to my app). My app still shows a new firmware is available to install but download button doesn't work because it informs "Aircraft low battery can not be upgraded" even if all my batteries are fully charged.
I've tried hundred times to pair RC and aircraft as well as reinstalling a firmware manually with SDcard (according to manual and Autel videos, step by step). Nothing works. I even tried to use downgrade my firmware but manual installing doesn't even begins (in all cases).
I also repeated everything with downgraded app to V1.2.11 but still no effects (originally I had the latest version).
Interestingly, that booting sound signal completely gone (sound known from booting aircraft /3 seconds on battery button/).
I'll be glad for help. I'm completely stuck.
