Thanks to all who encourage me try.
Yes I had tried but its was a bit slow in compare to 8.1. And obviously it should right now. After spending two days with 10 build I rolled back to 8.1 via windows recovery tool. And successfully installed the 8.1 in my Lumia 525.
but what I am missing now in my phone is CORTANA, APP FOLDER IN HOME SCREEN and many little things. and then I tried to update phone. But its giving me an error > 80072ee7 . What does it mean and how to solve this ? I m sure that My phone is not up to date with Lumia s official latest software for Lumia 525. Any help regarding this?
