J330F Enable diag port


If I dial *#0808# on phone, nothing shows up.
I need to enable diag port to perform 'read codes via server' operation.
I have reflashed phone with original Product code firmware but still not working.
Any idea please...

I do not want to root phone as it may trip knox

If still not ok, then do Wipe from recovery as well

Flashing different region or different product code version into phone may result in reading wrong codes or not at all.
Can anybody help with lower version of the same region product code for my phone? I will appreciate. Thanks
