how can I install this test fw? I have installed stable, and international version MX4. When i try install this or downgrade to 4.0.4 i get fw corrupted

Downgrade to 4.5.6 I,then to 4.0.4 I and clear data+factory reset. When you finish put A and enjoy!

As I can see, you are with international device, so go ahead. -> 4.5.6 -> 4.0.4 -> ;)

Thanks for fast replay, everything works fine ;)

one more question, when I turn browser - Google Chrome, my notification bar becomes black. Is any way to fix this?

The same is with me. Maybe you can try with other version of google hrome…

Is there any positive reason to change my stable version with this beta? Please, test it and share, as soon as it possible.

Are notifications working now ? … it’s absolutely crazy that the problem is still not fixed

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
