Good morning. I have an Infinix hot 6 pro version of 3Gb Ram and 32Gb Rom but my problem with it is I can only use 4G on the SIM 1and the SIM 2 only brings 2G network even though it has option for 3 and 4G. When the Sun 2 is set to 3G or 4G it display no network except when it's in automatic mode and only shows 2G network only. How can you help or maybe provide me with stock rom to flash it
