    Hi all,

    As i had my Iphone 3gs with new bootrom jailbroken on 3.1.2 with blackran thered JB, i used the spirit JB to get it unthered, but got messed up.

    I was not able to restore as i did not save my SHSH blobs.
    I checked up the web for a proper solution, none existed.

    so the only thing left was to try out the to upgared to IOS4 and JB as i was on 3.1.2 i took a chance.

    The steps are decribed below

    Damm lucky as i was on 3.1.2, i was able to install the custom IOS4 firmware and also boot it, did a carrier unlock. it wall works perfecly well.

    Have some good patience and read the steps carefully.

    so any guys out there messed up with blackran and spirit on 3.1.2, this is your chance.

    all the best.

    on my jailbroken IOS4 , iphone 3gs with new bootrom
