Thread: downgrading 3GS from 5.0.1 to 4.3.3

  1. #1
    Default downgrading 3GS from 5.0.1 to 4.3.3
    i have 3gs old bootrom which i updated to 5.0.1 using snowbreeze, kept the baseband so i'll be able to use ultrasnow, and i did all worked fine
    but since moving to IOS5 iphone is very slow so i wanna downgrade to IOS 4.3.3 - i have SHSH blobs saved

    my questions is how do i downgrade it without changing the baseband?

    Hi there.

    Normally, if you are downgrading to 4.3.3 there should be no baseband issues.

    But what you can do is download the 4.3.3 ipsw and make a custom ipsw through snowbreeze or redsn0w and then use that to downgrade.

    I am surprised that the 3gs with ios 5.0.1 is slow, most people report that it is actually faster.

    Have you loaded winterboard? (if you, that might be the reason why, winterboard in ios 5 is a bit heavy for 3gs)
