SimCard not detected after flashing any rom

[tnkiller3]

I am using desire 320 and used to flash many roms normally without any problems
then one day after i rebooted my phone when i was on cm13 rom (took off the battery and changed my sd card) the Sim card isnt detected.. i thought the problem from my sim and i tried it on other phones and it seems to be working so i tried to go back to stock rom to check and i found my sim is working fine
and from that day... whatever the rom i flash, the sim is not detected at all
tried different lollilops and marshmellow roms and the same problem kept happening to me
even the roms that they used to work fine a month ago now dont detect my sim (while everything is fine on stock rom)
I know this is really strange but if anyone have any idea how to fix that he can share it with us because i am kinda stuck like this in my stock rom... :/
(maybe there is some files i can backup from stock rom before flashing?)

Make sure u r flashing the correct ROM for your device model, don't forget to flash the correct bootloader for lollipop, marshmalow before flashing the rom of choice

And backup ur EFS before flashing the ROMs, there are plenty of tools on play store that does that
