1st check bt&wifi address from ipad by connect it to 3u and read full info
2nd get orignal mac address for ipad by data backup from old ic or use gsx

If you changed the sn then you won't be able to activate in IOS 11, if you have a backup for IOS 10 then restore that version.

IOS 11 now compares the processor ID with the sn, some how it looks like they been keeping that information but never used it because is a violation to the security of your device since that is what is being used to encrypt data.

I wonder how a refurbished iphone / ipad gets a memory change or CPU replaced? some one has access to edit or inventory the new info.

Edit: in theory you should be able to upgrade memory if you use the same SN on your original memory chip.
