plz how can i solve this

try to flash it with modem file only from combination rom with the same Security level "U3" then Patch Certificate and then flash it with 4 file official rom it should be work

p.s : if android 7 you should downgrade to 6.0.1

Try Downgrade 5.1 then write modem file good luck....

when i write modem comb file "COMBINATION_OXA_FA60_J710FXXU3AQD1" after no baseband and there is not 5.1.1 rev3 then cant downgrade on 5.1.1 and im not sure that probleme is modem
