what happens is that I was bored that the verizon version only had android 4.4.2 decided to unlock bootloader and do s-off with a box called xtc-2 clip which was the only method I found to do the procedure and to exchange between different roms and with all android 7 I have the same problem I do not recognize the simreally? are you using latest build?
it should be good to support all variants.
excuse the bad English I use a translator
