Hi geeks, i got a Samsung Galaxy note 5, it's originally from sprint but it's unlocked. This device runs the last Android 5.1.1 update. When i tried to update it ota from system update, the files size was about 1.4gb which made me know I'm updating to marshmallow from lollipop (the build number later confirmed this). So after the update finished downloading, it gave me an error, invalid file bla bla bla and it didn't install.

Now i have located one of the latest 6.1 stock firmware file for my Samsung note 5 build version (sm n920p), if you have flashed a stock firmware on your Samsung device, please share your experience and how to.

And another question i have is if i flash marshmallow to it, will my device relock and i won't be able to use my mtn sim on it? Thanks
