The Google Nexus 4 is a very popular phone. A powerful CPU, combined with 2 GB of RAM and a relatively low price at launch made it an ideal choice of many XDA community members, myself included. Despite being a great device, and one which is still extremely popular, the Nexus 4 has some issues with LTE. As it never officially featured LTE connectivity, you need to do some tweaking to enable it, as ever since radio 0.48, LTE has been disabled.
Luckily, the community managed to find a solution by creating a hybrid of newest radios with 0.33, which was the last radio with LTE capabilities. Those hybrids were created by XDA Senior Member morrislee. They previously needed to be flashed with the PC, which increased difficulty and hassle for many. Luckily, this is all in the past, as XDA Senior Member bpear96 created an application to flash your desired radio with just one click. With this application, you can do three things: flash a stock modem starting from version 0.24 up to 0.98, flash an LTE Hybrid Modem, and enable/disable LTE support in your build.prop. If you plan to flash your modem with this application, you naturally have to make sure that your device is rooted. That’s pretty much the only requirement.
To try out this app you should visit the original thread. So if you’ve got a Nexus 4, make your way there and enjoy super fast LTE connectivity._________
