Bizarre problem after changing logic board
Ok do I had a mint condition iPhone 4 which had an activation lock . I changed the board for one in an old iPhone 4 I had which I knew the iCloud details
All went well the phone powered up , I disabled FMI and signed out if iCloud
I then erased all content and settings and to my horror was greeted with the activation lock screen bound still to the iCloud of the logic board I removed ?
How is this possible ? Is there another component aside from the logic board that stores the phones serial number etc ? I'm baffled and have never seen this before in countless others I have done
Any help greatly appreciated
