Update lollipop firmware without downgrade to KK?

[rrdna]

Is there a faster way to update the firmware without flashing KK, rooting and then reflashing the prerooted new firmware? Is this possible without loss of data?

Yes, just flash a lollipop FTF using flashtool.

If you want to keep root, just install recovery and flash a pre-rooted lollipop zip.


If you are currently not rooted and want root after update then you need to downgrade, root, install recovery and flash a pre-rooted lollipop zip
