Thread: Downgrade from 1.1.2 to 1.1.1 fails

    Default Downgrade from 1.1.2 to 1.1.1 fails
    Please help!

    I have a firmware 1.1.2 iPhone that I would like to downgrade to 1.1.1 to start the jailbreaking process.

    I'm using iTunes 7.5. Firmware 1.1.2 and 1.1.1 are on my harddrive.

    Here is what I do:

    1. Open iTunes and connect to iPhone
    2. Press power button and home button on the iPhone
    3. iTunes states that it has found an iPhone in recovery mode
    4. SHIFT+ RESTORE...choose 1.1.1
    5. Initiate downgrading
    6. Downgrading process finished. Error Message appears "Error 1015"

    I use jailbreak 1.1.2

    1. boot from recovery
    2. *3001#12345#* to check version
    3. It stats version "04.02.13_G"

    This means downgrading to 1.1.1 failed. How come????


    I have jailbroken many iPhones starting with this downgrade and it always worked.

    How come this time it doesn't?


    Please help!!

    I had this issues once before. The thing that fixed it was using a different computer (one that had never seen my iphone before). A reboot may work, although I never tried that. I had the SAME EXACT issues as you two are having, so hopefully my method works for you as well!

    I guess I should have read a little more in depth. I was stuck at the point where it would freeze up in the initiating downgrade step. So I have a few questions for you then. Is your phone OTB 1.1.2? have you ever upgraded to 1.1.3?

    I once prayed to God for an iPhone, but quickly found out He didn't work that way...so I stole an iPhone and prayed for His forgiveness.

    I finally got it to work. I don't know why, but all I had to do was to turn of my laptop that was connected to my WIFI as well (I am working on my PC).

    Sorry, I haven't upgraded to 1.1.3. I will do it once there is a jailbreak.

    Thanks all for your help!
