Anyone can confirm, is this firmware has "Cost saving" in messages app and Sony Entertainment Network and does this rom above shows NFC icon when NFC turned on?
I received it about an hour ago in Libya via PCC, Still downloading

@SteepedBarley, No no and no.
Mine does not have any of them.
soooo goood i install on mine z1 KSA work Like charm
Please and please upload it to another host!
Mega is so bad for Low connections speed because it can not be resumed!
Can anybody CONFIRM that those who had the sound issue earlier DON'T have it any longer with this new fix? I read somewhere that people are still experiencing sound cracking/ distortion for notifications.
Heating and battery draining... Solved?
The heating and draining issue concerning the initial 4.4.2 update was gone after one day and a couple of reboots. This rom does not have these issues. And as mentioned above works like a charm. Only strange thing is the fact that i cannot change the lockscreen background, anybody nows how to fix this?
Update is huge. There should be pause and resume option. I want speaker problem solved and i also want Kitkat to allow third party apps to edit external sd card. Whatever I'm still downloading its been an hour now
It shud ideally take you about 2.5 - 3 hrs on an average connection, don't worry :) the download is close to a 1GB.
