I ended up getting a replacement phone from Best Buy and I ended up flashing a older version of twrp before trying the latest 2.7.0. I did a few backups just to have a stock rom to return to if all failed. Somehow after I tried flashing the new mk4 roms, I lost my 4g LTE in the process of flashing different ROMS and none of my back ups for twrp would work so I ended flashing Philz recovery and then Digiblur just to get my phone working again.
I ended up requesting another replacement so I can have my 4g LTE again. My question is. Is it possible to wipe a 4g LTE key when rooting and also is Philz the way I should of went when I rooted to make a stock backup if everything fails? Anything I should make sure to back up in particular to make sure I dont wipe nothing important. I just want to be extra careful this time around.
The phone was already updated to MK4 when I received it. Any help is appreciated!
