I finally managed to get it.. without any firmware update etc.
and sounds really stupid..sorry quite banana (dunno what ching chong the dafang talking about)
1. Install t mihome
2. login and select mainland china
3. click add device and selected the Dafang
4. press the setup button at the bottom of camera till got some voice
5. press the button I hear the voice n proceed.
6. scan the qr code and got voice (dunno say what)
7. this part important... when u hear voice, dun click u hear the voice succesful... wait for 2 mins then click that green button (I saw this on one of the YouTube comments)
8. success!

what was my error is I pressed that 'hear voice successful' immediately after I scan the qr code and the voice comes out. then it will run, at 67% something says successful..then 80% become 'password error voice'

i wonder can record from phone right? i dunno where is it saved in my phone...can only snapshot..but cant find the video...is it because i didnt insert memory card?
