I bought my 83 year old mother an iPad 1.5 years ago and it has never left her house. It was purchased brand new from Harvey Norman, a large retail chain in Australia. It was NOT purchased online, was purchased in-store. Only she has ever used it (and myself to set it up for her).
Recently she had a problem with iMessage so I did a backup, updated the iOS and did a factory reset.
On restarting the unit, the Activation Screen says the unit is now locked to 5*****@qq.com. This is an email address I have NEVER used, it certainly was
not an email address I used to setup the iPad originally and now the iPad is a brick. Apple online customer service was of no help other than "you must
enter the Apple ID that is linked to the hardware ... or contact the owner of the current Apple ID to have it released." As this is impossible to do because the whole ID is not shown (masked by asterisks) it is encumbant of Apple to resolve the issue.
My belief is either one of 2 things...
1. this qq.com is a Chinese company (truth) and they manufacture knock off Apple products using the same Serial Number Scheme, so when they register an Apple product on iTunes, their account takes over the "ownership" of the device.
2. it's maybe possible that an app that was downloaded from the AppStore was acting like a Trojan to deliver serial number info to qq.com and was used to hijack the device.
Either way, Apple's product/database has been compromised and Apple need to get onto this ASAP.
It is interesting to see that so many people have had the same issue with the same domain name as the Apple ID (ie ******.qq.com) and APPLE IS DOING NOTHING ABOUT IT.
