I can't return it to the seller, it's from Banggood.
The charger and charging cable are not the issue.
I have also tried putting it in the freezer for 2 days.
My MB3 is still dead, probably forever. :(
Well, the screen remains black even if I put it on the charger.
I guess, it's dead. :(
Still unbelievable how it could die from flashing official firmware.
Hi!
The 2.0.0.4 custom English Bold firmware was running on my Mi Band 3 with official Mi Fit from Play Store. Then I updated the Mi Fit app which upgraded the band's firmware to the official 2.2.0.14 firmware successfully. After that my band's screen has turned off and there is no life in it...
