How do I upgrade to Android Lollipop?
There are various methods to upgrade your Phone to lollipop. If were a little more specific about your phone model and and android version running on it. I would have suggested a little more direct approach with helpful links. But, try these steps for a Android 5.0 Upgrade:First search for the official update of lollipop for your phone. If you are using moto G,X, or sony Z or nexus, LG. Official updates are already available or in last Phases of development.If the official update is not available and you like tinkering then i suggest you go for custom ROMs as for most of the Phones custom ROMs are available with few bugs. But, if you like to play safe (then you should probably wait ) as flashing a custom ROM voids your phones warranty and many time your phone ends up bricked except for a few manufacturers which allows rooting and flashing of custom ROMs like oneplus and Yureka.If you really want 5.0 then Firstly find the custom ROMs for your device. You can go for cyanogenmod but CM12 stable version is yet to com or MIUI and there a lot of custom ROMs you can find it on XDA developers site.Then you have to root your phone and flash CWM(Clockwork recovery Mode) or TWRP(Team Win Recovery Project) which can be done by downloading the files in .zip format and flashing it either via official recovery mode or by ODINAfter flashing the CWM/TWRP. Place the custom rom also in .zip format in the device and start it in custom recovery mode (by pressing the volume down and power button simultaneously, it can vary depending on the device and manufacturer) then flash the rom.But, before doing all this make sure you back-up all your important files contacts and sms's as while flashing everything will be deleted. WARNING : Please read all the things carefully before flashing and a little knowledge of rooting will come in handy, read it on the link below .
