Device gets stuck in a boot cycle following the marshmallow release.
I'm not familiar with programming, but I downloaded the Android 6.0, marshmallow update on my Nexus 5 and it's stuck during the boot animation with the four balls. Others on forums suggested clearing the cache, but that didn't fix the issue. The only other option I know of is resetting the device to its factory settings, without losing any data.
Do you have a modified operating system installed on your device?
Well, at least it's not completely bricked. You may have to re-flash (or factory reset) your phone, you will lose your data, unless there is a way to pull it out with odin mode or smth, I'm not knowledgeable on phone software that much, don't know what you should look for. That's what I did when upgrading from stock to CyanogenMod, got stuck re-flashed and tried another way. When upgrading phones, ALWAYS backup desirable data, such things happen often with phones, because phones are very sensitive compared to PC's, their architectures vary wildly and even minor mistakes can leave you either bricked or with data loss.
