SM-G920P SuperIMEI repair problem….


I have been trying for a few days now to get this super imei to write to the phone with out any success. I have wiped the efs many times, factory reset, custom roms, downgrading as much as possible, everything i can think of. I have root, and wipe the efs, then i enable uart with echo 1 > /sys/class/sec/switch/uart_en. Then when it asks me to connect uart i dial *#0*# and it connects fine, writes the imei and then fails on the imei cert, heres a log of this if anyone could help, thank you.
