I saved my SHSH file when I was on 4.0.1 but when I load tiny unmbrella it shows 4.0.2 and will not load 4.0.1 in itunes. What do I do? phone stuck on apple screen.
When did you save your SHSH? What firmware you have on your phone is entirely irrelevant to what SHSH you get when you click "Make My Life Easier" or use TinyUmbrella to get your ECID "on-file." Instead, the determining factor is what what version of the firmware Apple is currently signing on the date you get "on-file." This is because the only source of valid SHSHs is Apple's server; they are not stored anywhere on your phone, nor is it possible to generate them without knowing Apple's private signing key. Once Apple stops signing a firmware version, it is no longer possible to save your SHSH for that version either in Cydia or using TinyUmbrella.
The following are the cut-off dates, followed by the version(s) you will have on-file if you get on-file
before each date:
Before 9 Sep 2009: 3.0, 3.1, 3.1.2, 3.1.3, 4.0, 4.0.1, 4.0.2
Before 8 Oct 2009: 3.1, 3.1.2, 3.1.3, 4.0, 4.0.1, 4.0.2
Before 2 Feb 2010: 3.1.2, 3.1.3, 4.0, 4.0.1, 4.0.2
Before 21 Jun 2010: 3.1.3, 4.0, 4.0.1, 4.0.2
Before 15 Jul 2010: 4.0, 4.0.1, 4.0.2
Before 19 Aug 2010: 4.0.1, 4.0.2
19 Aug 2010 and after: 4.0.2
Note: It can sometimes take several days after you click "Make My Life Easier" to work your way to the head of the queue, so it is possible that those who clicked "Make My Life Easier" in the days immediately before a cutoff will still not have that version on-file.
