So my classmate (or wherever you say it in english) gave me her phone as she knows im a bit techie, and she said when she tried to upgrade from older win10mobile version to new the gears started spinning and it just kinda bricked. I tried to do hard reset, and it wouldnt even show the ! The phone is lumia 635, and i will post a pic of it if needed, but the screen shows a screen taken directly from the pc version as it says to try put a disc and do that and that... Hope you could understand me cause english is not my first language.
