According to the latest reports we received from our readers, Huawei is finally pushing out official Android 4.4 update for people in some European countries such as Hungary,Romania and Czech Republic. This new B510 update seems to be the same one pushed to registered beta testers in Germany not too long ago. There is speculation and rumors going on that Huawei rushed and outed the beta firmware as official one, but knowing Huawei’s numbering scheme B510 still could be the final official one intended for release in Europe. 
Here are some details about this official firmware
Compatible Model – Ascend P6-U06
Firmware version – B510
Android version – 4.4.2 KitKat
Emotion UI version – EMUI 2.3
Kernel version – 3.0.8-00787
Size – 775MB
Region – Europe
English language is included
We won’t go through describing the changelog here because you guys have probably know the changes by now because of the leaked and official Chinese firmwares. Basically this update brings the new EMUI 2.3 user interface and few new software additions to the camera and power saving features.

Again we still don’t know why Huawei pushed B510 firmware as a beta one to Germany and  as a official one to others. The download file below is obtained from the official B510 release and not the B510 German beta release. So if future proves that both B510 aren’t the same you can be rest assured that we have provided you the official release.
Make sure that you are running B132 firmware before installing this new B510 release. This B510 was pushed to the users running official B132 firmware http://huaweinews.com/2014/03/ascend-p6-b132-firmware/ and early adopters of B510 reported us that B510 won’t install correctly as the previous leaked KitKat firmwares unless you are running B132 prior installing B510.
