I am currently on rooted marshmallow and want to return back to kitkat. I was able to unlock my bootloader successfully then had flashed the magisk rooted MM stock rom. I'm having an issue with a Sim card error notification after awhile then my verizon service gets disrupted. The only way to get my service back is to re-flash the MM rom. Also the external sd card cant be formated as internal storage therefore i'm not able to do my regular backups in twrp. The system font size is too small as well! I've researched this problem for an entire day and asked about the MM rom issue in the following forum where I got the rom from and unlocked my bootloader.

I've tried to flash in odin the following file ALL_VZW_G900VVRU1ANCG_G900VVZW1ANCG_964333_REV00_user_low_ship_MULTI_CERT.tar file but it failed! When I was on kitkat it worked if I had to return to stock.

Right now I'm downloading VZW-G900VVRU1ANCG-20140410100641 file in hopes i'll be able to return back to kitkat. Is this not possible?
All help is greatly appreciated! Thanks!
