Has anyone successfully unlocked bands on the Chinese 1+2?

I mistakenly bought a Chinese 1+2, as a result I don't get LTE or HSPA+, and barely have any HSPA service in Canada. I've read guides for the OnePlus one but they seem device specific. Has anyone successfully unlocked either HSPA+ or LTE bands for north America on a Chinese model?

Rooting does not work (Custom Recovery CWM installed successfully)

Hey there.
I unlocked the bootloader and installed CWM.
But I fail at rooting the device. Each and every superuser.zip or SuperSU*.zip failed - the app is always installed (via CWM recovery) but the manager app claims that the binary does not exist after rebooting.

I tried SuperSU 2.74 beta (latest, https://download.chainfire.eu/supersu) and 1.80 among others.
Kingo Roots fails in the apk variant and keeps stuck in "installing drivers" when using the windows version.

I've been trying to root the device for about 10 hours now - any ideas?

Android is 4.1.1 stock

I dont want to use a custom rom, as from what I read they are not very "mature", but rather unstable.

you can use this app from the play store to install custom roms without a custom recovery
