Hello. I am new to the forum, from Argentina . I have a problem and hope someone can help me. I have a Samsung GT- i9150 Mega 5.8 . I bought it in January 2014 Everything was going well until I happened to install two apps to customize . Xposed and unicon . After overcome the intimidating poster brick , try installing the xposed and could not. From that moment I saw that the wifi was no longer the same. Is connected and disconnected . But figuring insisted and managed to install xposed and I customized the Mega unicon without installing a custom rom or launcher . And from there the wifi did not connect more . I changed my rom , I did hard reset , and was connected only got a few hours a day and no more luggage . The swich is always looking to activate wifi but fails . I took it to a technician and he said you have to change the plate but I resist because the phone goes swimmingly at all , the only thing it does not have wifi. Lei Xposed out there that make changes that are not removed to make flash a new rom , so I tried Xposed Disabler from recovery and had no good result. So far I 've come . I bought a portable wifi tp link but I could not install the drivers for you to read . If anyone can help me thank you from now on.
