I know I sound like a total noob for the title alone, but I think this is something more complicated than you may have probably thought. My father gave me a ring, but my phone was locked back then. Now, I tried to answer the call but the screen was black and blank but my back and menu keys were lighting up. But I had to "cancel the call", but I wanted to know the time back then, so I proceeded to try and unlock the phone but to no avail. So, I had to try and take out the battery since my phone probably had crashed or something. Now, upon rebooting I'm now faced with a bootloop problem. I tried reflashing my rom, formatting /system and also flashing my previous Kitkat roms but still to no avail. Now, I do hope a kind soul can help me with this problem... please?
