Recently, many iOS users complained that there is an annoying unknown error 3503 in iTunes, which stop them from restoring and updating. In fact, Apple isn’t made a full explanation of iTunes error code 3503 yet.
On 3uTools, the error is “Unable to request SHSH”. And on iTunes, it is an unknown error (3503). After we tested and researched, our developer team find out that this issue may be caused by Apple server. As a result, users can not restore their iDevices using iTunes or earlier versions of 3uTools.
3u Team try our best to solve this issue as soon as possible. And finally, we released a new version of 3uTools, V2.16 to fix this.
