Apple introduced activation lock in iOS 7 back in WWDC 2013. Which some
people thought that it was a great thing. Some like it but some don't.
whatever anybody say about them but in my opinion they are hero, who defeated apples foolproof security.
When i come to know about it, many Questions came into my mind that if
someone forgets his password or id what will he do.. or if any body buy
an iDevice in such country where apple is not available. what will
he/she do.
Same thing happened with me. i own an iphone 5 since iOS 6, but i bought
it from some one else, i used it on iOS7, till iOS 7.0.6, But when i
updated it on iOS 7.1 it get stucked. when i called Apple they refused
to help me.
I was about to throw my iPhone in a trash. but after some months i came to know about DoulCi.net.
About DoulCi
It is a group of fantastic hackers. who succeeded to Bypass iCloud
activation lock, by creating a fake apple server, and communicating with
the device to bypass.
there method is still in beta form but really effective. DoulciTeam contain two persons known as AquaXetine & MerrukTechnolog. you can follow them on twitter for more updates.
It is still in working progress. carrier do not work and have some boot
loop issues but will be fixed. There server is not always working as it
is still beta, but they often do a beta test. and i my self bypassed my
iPhone 5 with this method.
