When I got my phone I immediately updated to Kitkat. I just like all my devices and apps updated to the newest, no matter how good or bad the new update is After I read that the battery life of Jellybean is incredibly better than the one from kitkat I decided that a downgrade would be a good thing.
I know that this question was already asked by rubez but I don't believe it is as easy as just flashing the jellybean ftf through flashtool. In some other threads people wrote that the phone can easily brake if you don't check the right options in flashtool. I'm very confused over all the different opinions the people had. Furtheron I want to stay rooted when downgrading, so this makes my dilemma more difficult.
So can (preferably) an expert tell me how to do downgrade to jellybean without loosing root?
Can I use the instructions from this thread although it's seems only to be for UPDATES?
Btw, what exactly do I lose if I downgrade to Jellybean?
Thanks in advance!
