[Xiaomi Redmi Note 3 Questions & Answers] jaozze:
Hello!

I just received the phone today, everything was OK. I charged until 99% and tried to unlock it with my fingerprint (that was working well 30 min before) and i couldn't unlock the phone. So i went to 'Settings' and delete the fingerprint, and now i can't even enter into lock screen & fingerprint menu. I wipe all data, and flash again the official ROM (the same that had the mobile phone), and nothing solve it. When i try to enter in lock screen menu, the menu opens and goes back again into settings menu and dont let me change even my pattern. Some suggestion?

Here a screenshot of "settings":

Here some fragment of logcat where i try to open te settings->lockscreen->lockscreen & fingerprint

I've tried both of the official roms, clean flash, wipe factory, and gives me no fix. I've open the case and remove de FP ribbon for the fingerprint connector from the motherboard to check the fingerprint sensor and same issue.

Any idea how to proceed? test it? access in some "safe mode"?

i really dont care a lot about the fingerprint but the security settings are important (Set some password or pattern)

I've buyed on aliexpress and warranty process is painful an expensive as i have to pay the shipment back and i had to pay VAT for it.

Thanks!
