Cannot activate after changing IC data and Audio

Good Morning,

I cannot activate the phone after changing the IC, I changed IC audio and IC data and other parts in the phone but I finished, I reset the phone so I can restore the backup but I couldn’t activate it

I tried force restart, activate with different WiFi, different SIM cards but nothing working.

And iTunes gives me black screen, I used other softwares to restore the backup but when I boot I always get the same message “ Couldn’t Activate iPhone”

P.S : the IMEI and serial number are correct on iTunes

Any ideas ?

Thank you

If you mean you changed the nand ic unless you copied the codes from the original nand then that could be the issue
