Hi Guys, I have successfully upgraded my 7D-501L with firmware
7D-503LV100R002C208B009.
It's an EMUI 3.0 KitKat 4.4.2 and I guese it's 320 dpi as I compare the text size earlier on 2.3 its visibly smaller.
1) I am using the dload zip file downloaded in this website:
http://forum.xda-developers.com/huawei-med...20-dpi-t2923307
2)Then the latest China Media Pad X1(7D-503L) B009 (EMUI3.0_Android4.4) dated 9th January from this website:
http://www.emui.com/plugin.php?id=hwdownlo...d=detail&mid=64
3)Unzip the dload zip file and replace the update.app file with the downloaded B009 update.app
4)So the dload copy to micro SD card as per usual into the tablet and begin the process.

I am still testing the tablet but do share with me too if you have this EMUI 3.0 in your tablet
