The Verizon and AT&T variants of the LG G2 have been Loki hacked which means that they are now capable of running Team Win Recovery Project. We still aren't able to do this on the HTC One or the latest GS4 update. Loki does not mean that your bootloader is unlocked, however this works just as if the bootloader were unlocked. With this hack you can flash Roms and Kernels. Downloads are available for the Verizon, AT&T, Tmobile, and Korean Telcom variants. Check out the source link for the download links.
