    Can you confirm whether this was an official Samsung/Sammobile firmware that you flashed?

    Can you install this app and post:
    Product Code
    Original CSC code
    Active CSC code
    PDA version
    CSC version
    Baseband version
    Android version
    Mobile operator

    The original CSC code is for China.
    It looks like you have tried to convert a Chinese phone (probably an SM-A3000) using A310F firmware.
    This is why the phone has lost its IMEI.

    Re-flash the original firmware and you may be able to recover your IMEI.

    This is my guess at the original firmware.
    What does the phone model say in Settings and Download mode?

    Having an original CSC code of CHN (China) when China does not have the SM-A310F is what is puzzling me.
    Something is not right.

    Use SmartSwitch to re-install your original but latest firmware:

    Ok, that adds to the mystery.
    The Firmware on SmartSwitch is shown as OLE (XXX)
    XXX is not a samsung csc code, and we know from post #3 that you have Germany Vodafone firmware.
    By the way, this firmware is not up to date as you can see here:

    I am very unsure about this phone.
    I believe that it has been modified - you can check this in the INFO app by using the menu top left.
    Look at
    Refurbishment check
    IMEI and S/N check

    There is a new FRP bypass from Root Junky.
    Hit the internet today.
    If you have the FRP problem try it.
