i use old mi fit mod for unlock nfc menu first, after that it require an chinese id card photo. I got photos from google and print it. Final, scan photos in mi fit
No need to use that Mod version. I got access to the NFC menu in my Mi Band 4 following these steps:
- Signed up with a new account at xiaomi.com using my laptop.
- Chose China Mainland as a region (大陆地区).
- Unpaired and logged out from Mi Fit app.
- Logged out my Mi account in my phone.
- Logged in with my chinese account.
- Open Mi Fit
- Logged in with the chinese account.
- 'Create access card' menu is accesible now!
BUT, can't create any access card or Mi blank card because the app asks for a Chinese ID Card!!
