    I am currently on an iPhone 4 (not verizon) on 4.3.2. I have all my SHSH's saved, and I want to go back to 4.2.1.

    Can someone give me a quick step by step guide.. here's what I tried, but it failed..

    1) turn iphone off
    2) put in DFU
    3) open tiny umbrella, iphone isn't recognized since it's in DFU, so i just hit "start tss server"
    4) open itunes, shift+click and selected the 4.2.1 image. I keep getting error 1601.

    what am i doing wrong?
