I was using EMui for a long time, but suddenly my WIFI seems to be broken. It disconnected from my WIFI all the time while it did see the network.
So I decided to installed MIUI... I think i did something wrong because MIUI is extremly laggy and is simply not working. Apps continuesly fail. and once I get into the lockscreen I can't get it unlocked any more. The screen remains black. I did flash MIUI again but It remained a problem. Any Idea what I could have done wrong? I installed the 5.5.29 version. I'm now downloading the 5.5.27 version hoping this will work better.
any suggestions are welcome.
UPDATE: I think the newest TWRP casued the problems. I'm know running 5.5.27

However my networking issue is not fixed. It sometimes connect to a WIFI network and than is unable to connect to the internet and soon loses connection with the network again. While it still sees the network... I think my wifi is broken somehow. But I have no clue what it could be. It always work just fine, but started to behave like this a couple of weeks ago.
