Default [Q] Help! Quick Charge 2.0

I hope someone can help me out with this. I was made aware back in March that the HTC One M8 supported something called 'Quick Charge 2.0'. According to Qualcomm, all smartphones with Snapdragon 800 and 801 processors (to include phones like the Xperia Z2, GS5 and HTC One M8) supported Quick Charge 2.0 by default.

I bought the only official Quick Charge 2.0 charger available which is the NTT Docomo AC Adapter 05, imported from Japan. I just received it in the mail today and am testing it out on my phone, and it is not charging at Qualcomm's advertised Quick Charge 2.0 speeds, only at the regular speed. I don't know what to do to fix this. Can anyone help me out?

If your phone is completely stock, then it might require a kernel update (from HTC) to support QC2. It's also possible that, for some reason, the specific charger you got won't work with this phone. No one here is going to be able to help much for a charging standard that doesn't exist in the region yet.

Received confirmation from HTC that QC 2.0 has been disabled on the US handsets. An OTA update is supposed to be released to support it, someday. For now I'm gonna try a kernel that supports fast charging to see if that works. According to qualcomm all 2.0 spec chargers should work with all 2.0 spec phones, there's shouldn't be any chargers that work with some phones and not with others. So we'll see.

It seems I was premature. After some more testing it appears that quick charge IS working and the problem was the battery stats not being reported correctly. Phone just charged from 24% to 46% in about 10 minutes! That's a vast improvement over the Quick Charge 1.0 speed. Gonna charge/discharge a few more times in order to get some correct readings.
