Thread: HELP PLEASE! Need to restore 3GS (3.1) without updating

    Default HELP PLEASE! Need to restore 3GS (3.1) without updating
    Hey everyone,

    I need some help. I'm selling my iphone 3GS and the key to the sale is that my phone is still running firmware 3.1 (7C144), so it's unlockable.

    I'm selling my phone in a few hours. I just backed it up, and then went to restore it, and it says it will automatically update to the newest firmware. If that happens, my sale is dead.

    How how how do i restore my 3GS back to factory settings, but still keep the 3.1 firmware intact?

    Is it easier/less risky to manually delete everything from the phone and then sell it?

    Thanks so much in advance! I really appreciate the help here..

    Best,

    GB

    Restore to 3.1.3 , and put in your official sim card, let it activate.
    Run Spirit jailbreak if you want to jailbreak it.

    but i thought that there aren't good jailbreaks for 3.1.3 yet? The person buying my phone will want to jailbreak it, and that's why it's apparently important not to update it. You're saying if i update from 3.1 to 3.1.3 it's still jailbreakable and unlockable for use in another country? That's the reason the person wants to buy it from me.

    If so, how do i restore to 3.1.3 if it's never even been installed?

    If you are selling your Iphone as 3.1 and not jailbroken nor unlock, then just do a reset under settings and manually delete everything.

    Download 3.1.3 ipsw from here iClarified - iPhone - Where To Download iPhone Firmware Files From
    Do a shifr + restore to 3.1.3
    Insert your official sim card
    Run Spirit jailbreak from Spirit
    Open up Cydia
    Install Ultrasn0w.
    You are then jailbroken at 3.1.3 and unlocked.

    ah! ok. That makes sense. That will remove everything in the same way a restore would and it'll be clean and clear and ready to sell?

    Thanks so much for you help i really appreciate it.
