It is impossible to enable radios on a phone when they don't exist. Only the RM-820 variant has the AWS radios in the wireless modem. This is why you are able to possibly enable the respected radios with the AT&T model after flashing, due to them disabling the AWS radios for WCDMA/UMTS. On the European/international units, they use an entirely different LTE module to work with LTE networks outside the Americas (Russia for example uses the 2600MHz band for LTE, a frequency not present on the Americas' version). This incompatibility issue though, is good for power users, and LTE users everywhere. If your device was broadcasting all these different frequencies at once, the modem would simply drain your battery extremely fast. In the future, Qualcomm will release chipsets that will have all the frequencies needed on a single modem. The firmware would then optimize the LTE bands you need to use that operator's LTE network. Keep your hopes up and hope they release this within the next two years!
