Uninstall official lollipop Samsung Galaxy s5 Yesterday, I installed android Lollipop on my Samsung Galaxy s5. It was an offical update, since I dont like to flash my device, because it is a work mobile. 

However, this offical lollipop release from Samsung keeps crashing. It crashes while the screen is off and I want the turn it on again. The indicator LED flashes and the device reboots. This doesn´t happen every time, but it does happen extremely often. So my phone is unworkable. 

I cleaned the cache partition of the device but this did not help. So to remedy this problem, I want to uninstall lollipop and revert back to Kitkat. However, when I do a factory reset, it will only whipe my personal data, not the update.  

What should I do?
Yes, you can, with Odin! Done it couple of times, but unfortunately it will start to download the Lollipop update again and will continue to keep asking you to install it. :(
