It's fake on obviously add new says xda tutorial and that's nothing in this section on it or the other areas for our p7.
As above no cwm on p7 twm is what is used it seems, also he doesn't state model number remember there all imcompatible the roms as all the l10 people are unhappy that's no Dev emui 3 ROM or that device.
The kernel has only been recently released publicly for our devices and you will see any custom rom on this forum is a early test version.
The screenshot is edited KOT49H is the 4.4.2 build number lollipop uses something else and is a white background I'm running it on my nexus 10 right now.
Also emui 3.0 on 4.4 isn't out till next week.
I do hope huawei release a v5 lolipop rom but when or if they will announce it I don't know.
Allot of companies like to sell new devices than update them to the new versions.
These scams have been going round for years for many things not just android Roms where they take something and sightly edit it and put links behind a survey host.
