How can I chek the IOS revision loaded? I know I could print it off with prinf (iosrevision); or something like that. And use an if something == revnumber ?

Would this work? and if not how would I?

(Excuse fail typing)

You know you don't have to call IOS_ReloadIOS() to be able to see the revision of an IOS ;-)

So, you're basically trying to see how to printf() the revision of any IOS?

Basicly... I want this:

You load IOS (I need it to load IOS35) (Complete)
Check revision (Complete)
Print revision (Complete)
Compare it to whatever revision I put (Stuck D:)

Here is an example ! (Not real code lol)
if (revision = 2910);
{
// This
}

Something similar to this would be perfect. Unfortunately I can't get it right.

since you are checking the version and revision AFTER you load the ios, you can just say

IOS_ReloadIOS(35);
printf("IOS: %d (v%d)",IOS_GetVersion(), IOS_GetRevision());

you only need to use the signed blobs and ES calls if you want to check a IOS version and what not BEFORE you load it.
