[Huawei Ascend P6, Mate] @roKiLL:
Yes, I've with the same situation. My girlfriend got the same unit, the seller as a lyer and don't like the return of the phone. It's sold how as P6 with K3V2oem1. Firstly, sorry for my english. I can't train it, and I'm better reading than writing..:(

First, after doing anything make a full backup. The CPU how says in other messages is a MT6589.

Download the MT Droid Tools 2.5.3 (Click here)

The Drivers for MT65xx. Mega Drivers MT65xx Pack & Installer. The better drivers what i found are that.

Download Mobileuncle Tools (Download here) APK

Download latest Framaroot (Click here)

Remember, we don't have Google Play and we can't install apps. We need all the files what i've mentioned above. Go to Security and mark the Unknown Sources. Later, activate the USB Debugging. Click around 10 time in Compilation Number at About Phone, and activate Debugging Options.

Put the APK downloaden; Framaroot, and install MobileUncle Tools; in SD card o Internal Storage and Install It.

Install the drivers, for full working, and download the MT Droid Tools. Extract in a Folder without spaces. How C:\ or D:\... if the OS as winXP install at root directory. If it as Vista/7/8 you can extract in Desktop, or Download Folder. Remember, the path never contains a space. The OS linux and the software that works with linux architecture do some failures with I/O (Error on read the path adress for the spaces). Ok, before that, let's go.

Open the MT Droid Tools. When it connect to Phone, show a message how this "ATTENTION! Imitation Hardware or firmware in the kernel does not match phone!" (In Spanish "ATENCIÓN! Imitacion de Hardware en el kernel o firmware no se corresponde con teléfono! "). Ta-Da! This phone is a Fake! Full Replica. Ok. Now the lower rectangle, wait 10 seconds, and it's filled in yellow. Click at ROOT. Now, click at "Root, Backup, Recovery". And click "Backup". If it shows a message showing "The sd card not inserted", else click Yes to Continue. It ask for pack the backup, click at "No". We need now the Recovery file. Wait some minutes, about 10. When it's terminate, click at "select boot.img file" and click at button "Recovery and Boot". Caution with this. Go with that procedures. First select the boot.img in the backup directory and it's shows a message asking if it make the CWM Recovery Automatic. Click Yes. The 2nd an 3rd step ask if it install at the phone. Always click at NO. OK? If you click at yes I don't responsive. And I don't know what happens. Ok. The file Is created. Put it into the Internal Storage.

Open the Mobileuncle Tools and select "Change Recovery". The first value is the located in the Internal Storage. Click Accept, and if it ask reboot in Recovery, Accept.

Now, in CWM recovery. select "Mounts and Storage", and mount all. (Data, System, Cache and very important, sdcard).

Open MT Droid Tools, and again. Backup. But now, the message showing the issue with the backup from nvram and system, don't show it. And click Yes when it asks for compress the Backup

After all these steps. Congratulations, You got a Full backup from this device.

Now, got to install the Google Apps.

Put the Gapps.zip in the sdcard and install it with the CWM Recovery. Download Here

Ta-Da! Full working phone. At now. Search for MTXX devices or MT6589T CPU's.

Sorry. I forget that i'm trying to make a better custom firmware removing the Chinese apps, putting Go Launcher as Default and with some apps very useful.

I need some firmwares for debugging. I see a lot of bugs and i'm going crazy searching for that in frameworks.
