Hi! A few days ago my phone discharged completely. I let it charge for a while and when it turned back on it entered a Test Mode screen. No matter what I did it wouldn't exit that screen. I eventually managed to enter into recovery and did a factory reset. All well until the wi-fi connection screen: it would show me the wireless connections available, I can click on them and enter the password, but when I try to connect it would just show me saved on any connection and not connect at all. Sometimes it displays network connection error. I even reinstalled 3 versions of ZUI but all in vain. Same issue. I tried advanced options like wps connection and static ip, but with no luck. (Btw, my 4G connection works perfect) Could it be a board issue? Any help would be much appreciated.
