[Dejan Manic]

Hi i wanted to install the new update on my phone and after it turned my phone off to install i saw 2 gears, they were on for like an hour and i got frustrated and pulled out my battery and got it back in and now i only see a black screen after the nokia logo, thats means i halted the installation but i dont know how to fix it now both hard and soft resets are not working and nokia suite tells me lumia 620 is not supported

I'm not sure, but it seems like you have to take your phone back to Nokia
