Samsung Galaxy Note 3 Firmware update help!!!!
Hey guys

I am completely new to forums and even more so to updating my firmware. Im trying to update my Galaxy Note 3 from Android 4.3 to Lollipop 5.0. I cant seem to do this and now I cant get into my phone. I have tried putting the original 4.3 back on by downloading the files and also cant seem to do that. This is the error I get when i try download the firmware onto my phone.

When I initially started the process I followed step by step instructions. I have gone through as many forums as i can but cant seem to get my phone sorted. Please can someone help me?

5.0 Lollipop
