Can I install Google Edition Android on an HTC One X+? Recently, the HTC One Google Edition has been released which has Google Android 4.2.2. I'm currently using an HTC One X+ and I want to install Google's Android on my mobile. 
I've found some links on how to install vanilla Android on the HTC One:


Redmond Pie
XDA


I'm willing to install that on my mobile. Can I do that, and if so, are there any cons to doing that?

Is it possible to install vanilla Android on my phone so that every time the Android is updated, I get the updates directly from Google?
A ROM for the HTC One won't work on the HTC One X+. Despite the name similarity, they're completely different phones, with different hardware inside. (The HTC One X+ has a Tegra 3 SoC, while the HTC One has a Snapdragon.)

If you want to install a "stock Android" ROM on this phone, you'll have to find one first, and as there isn't a Google Play Edition for the One X+, this is very unlikely to exist. You might be best with a custom ROM that doesn't have many customizations. Generally, custom ROMs don't update over the air: you need to reflash whenever you want to upgrade to the latest version.
