I have a very similar problem with

Xiaomi Mijia Air Quality Tester | Xiaomi Mijia Air Detector | Air quality detector​

the latest ROM 3.5.7_0094 has some problems. And after it was updated on the device, it always freezes and could not connect to MiHome. The full reset could not help with this problem and i do not have any idea how to restore some previouse rom
Does anyone have an idea where to find a proper ROM and flash the device?
