I installed the OTA HTL22 stock 4.4.2 update with Sense 5.5 two days ago. Meh. Can't say I notice huge changes. Apart from the fact that AU has overwritten the Google emoji (morons - HTC told me that was a directive from AU to make sure that all other phones could see them properly. But it has broken them in Hangouts. Come on - this is Japan, and you screw with emoji, you gotta expect a backlash!!), and some other weirdness, I can't say I notice much. Battery life seems worse, not better, TBH.
I am regretting it now, as I'd love to root it and fix some stuff up as a result. But with a 1.57 bootloader, the whole downgrade stuff gives me the willies.
Anyone rooted after the latest OTA update? (and if so, can you point a semi-noob in the right direction? I don't want a custom ROM, just the unlock and root). Cheers
