http://forum.xda-developers.com/showthread.php?t=2774949

No choice had to factory reset.. now its ok, its a good thing of this phone for having small internal storage =.=

geez, i'm updating my hp before i see the posts
crossing my fingers

I also got the media error and had to factory reset the phone. Heck, the phone can't even access my memory card! After the reset, all seems to be smooth for me so far. No more error.

Guys.. Pls give ur tips on updating this firmware and give some review on battery life, memory usage and etc..
a bit hesitate to update as i'm happy with 4.3 at the moment..

So far so good. No glitches for me. Battery seems normal for the moment but we will see at the end of the day. One thing I noticed, and liked, is that we have the screenshot function back at power button long press.

Google service drained 20% of my battery while i was sleeping . It's only 2-3hours . Any idea to fix it ?

Btw benchmark on antutu even decreased to 20821,initially jellybean was 21664

been using rooted stock 4.4.2 for about 2 weeks, done the troubleshooting on battery drain issue...so far so good! previously on 4.3, bluetooth connection not stable ( frequent disconnect when pairing with sbh52 ). with 4.4.2 bluetooth is rock solid !

here's some screenshot on battery statistic;

For those who already update to kit kat did you facing a problem to transfer the file from internal memory to sd card?.

I didn't face that problem .

facing that problem since 4.3, transfer half way "Memory has stopped" .

I still dont dare to update to KK

To root, I need to downgrade to 4.1.2 (factory reset), then use DooMLoRD's tool?
After that can update OTA to 4.4.2 while still keeping root?

Can I use the program VROOT to root my xperia ZR? Or just use above method?

Currently running on stock 4.3 formware 10.4.1.B.0.101 with locked bootloader.

Last time I managed to root my ZR using doomlord method. But when update thru OTA failed to update. So I update thu pcc which will lost your root. But some people manage to update thru OTA with root. Worth to try.

Anyone having wifi connection issue? After a factory reset its fine, but then after a couple updates on the application, not able to connect to wifi again...

No wifi connectivity problems for me. All is well after my firmware update & factory reset.
