[chl3b]

Hi Hope this question was not asked before. For some reason app doesnt want synchronise with camera BFUS it is connected to Wi-Fi I can see view in onvifier and VIA VLC but IT doesnt wants to match with cloud, in settings page is enabled yi cloud. Any suggestions? I have also one other dam bricked IFUS cam completely nothing happening just LED is Amber and that is IT. I read some treads about how to unbrick but I am almost numb in this case, thinking to edit fw from the working if this is possible as is BFUS and IFUS or is any dumped backup firmware.
Status.json file displays

"name":"yi-hack-mstar",

"home_version":"4.5.0.0C_201910080934",
"model_suffix":"y203c",

Never seen this problem.
Try to reset the cam with the button and remove it from the app.
Then repeat the wizard to add the cam in the app.

About the other cam bricked, is it a MStar? If yes, I can send you a couple of file to try the restore procedure.
But I need to know the model or the fw version (I mean Yi firmware).
