Activation Lock Status Checker Removed
As it turns out, the Activation Lock website was a vital part of a bypass hack used to unlock devices bricked by Activation Lock, perhaps hinting at why Apple shelved it.
The process is demonstrated in the video below. By changing one or two characters of an invalid serial number, hackers are able to generate a valid serial number, using the Activation Lock tool for verification purposes to make sure it’s functional. That valid number, which belongs to a legitimate device owner, can then be used to unlock a previously non-functional iPhone or iPad.
The Activation Lock scheme that steals valid serial numbers from existing iOS users potentially explains a mysterious Apple ID bug that’s been plaguing iPhone owners for months.
