We may have QC2.0

[ImjuzCY]

I've always wondering why no one have came out with a way to enable Quick Charge 2.0 despite our phone is on the supported list. I Googled it, and found out that the Sony Xperia Z2 international version have the same situation as us. Sony didn't enable it on the International Version, but xda devs found some way to enable it. I'm no pro on these, as I'm not a dev, so I will leave a link here so that other devs will have a look and at least see some hope on QC2.0 in SD version of Redmi Note 3.

This was somewhat discussed before: [Snapdragon] Quick Charge 2.0 hardware is built-in but not enabled

Your link has some interesting information which could be useful. However, they already had a japanese firmware with QC2.0 support. They only needed to port it to other ROMs.
Neither the chinese and global firmware for RN3 has such support. But FWIW, the /system/bin contains the HVDCP module, which is further proof of possible QC2.0 hardware existing.
