Hi , I recently bought a Verizon S4 that came with a Baseband Version of I545VRUFNG6. Although I know that only Baseband Version VRUAMDK has an exploit which allows for unocking the system and placing a custom bootloader on it, I must ask: are there any options for this phone on this specific baseband? Are there any ROMS or a way to use FlashFire to get an Android version higher than 4.4.2? Or is there any way of downgrading the bootloader to VRUAMDK. I've read that downgrading to 4.3 is not possible. Just curious. Thanks!
