Hello , my brother gave me an almost new unlocked Verizon s5 . Is it possible to use this device with Sprint ? I'd like to root it and install a Sprint custom rom if this can be done . I run custom roms on my LG and other Samsung S3's and S4's but they were already Sprint devices . Can anyone throw a little advice on this ? I'v googled a lot and found lots of threads about running Verizon roms on a Sprint s5 but not the other way around . Thanks much ..
