Thank you so much for posting this!
Being a HOX+ (US) AT&T 4G LTE owner and devotee, I am truly inspired to attempt this mod.
Will I need to convert power from US to UK?
I will make sure to share pics if it turns out successfully.
A STANDARD MicroUSB ADAPTER WILL NOT WORK because it will not get enough power. You need something that outputs 9V and 1.67A or the phone can't keep up w/ the charge. The perfect adapter to purchase would be the one for the HTC flyer. I can verify that it works perfectly w/ the dock and US power. Here's a link to one on ebay.
So this worked on the the US version of the HOX+ on the European dock? I've been searching for a dock with pin charging for a while. Your method looks very simple. From what I gather, the pins only move over (down) the phone for the US version vs Euro version but are in the same orientation? Also a slight padding to go along the long edge in the dock to orient?
