Hey guys, i need your help. I decided to install Windows 10 TP today, but i was really disappointed. It started to lag, buttons were not working correctly. So i read a guide how to go back to WP8.1;) I connected my phone to PC, after downloading I've got an error at 11-12%:( It was booting into a strange looking red screen with NOKIA sign on it:rolleyes:(i guess it's called UEFI mode) After few errors i connected my phone to another usb port, and it wasn't even booting:crying: Phone is just bricked(it was charged up to 100%). Is the phone completely dead or it's still a chance:angel: Please help me, i am android nerd and... WIndows Phone noob:p
