Hi guys, In terms of post count I may be a newbie but I would like to think that in practice I am certainly not a newbie at the phone hacking game! However, I have a query I hope you can all help with ... I have an iPhone4 running 4.2.1 and have my shsh blobs backed up both locally and on cydia's servers as I want to be able to restore to 4.2.1 when Apple release later versions and are no longer signing the software. To simulate doing this I have entered the hostname entry as below and am trying to install a custom 4.2.1 ipsw using the shift / restore option in Windows: 188.8.131.52 gs.apple.com Every time, my restore fails with error: 1013 and the phone remains in recovery mode. I have read this is normal when restoring a custom ipsw and that you should use a tool such as tiny umbrella to exit recovery mode and the phone will boot but as this is no longer working on 4.2.1 this is not an option. Am I right in thinking that currently there is no way to restore a custom 4.2.1 ipsw whilst pointing to cydia's servers and bypassing apple's own or is there something I am not doing that I should be? I know I can restore 4.2.1 through iTunes using Apple's own server currently but I want to be sure I can do so when they stop signing the software, hence this test. Thanks!
