    Default HELP iphone 3gs restoring
    Ok guys heres the deal. I have an iphone 3gs running on 4.0.1 jailbroken by jailbreakme.com and unlocked by ultrasn0w. I want to just restore it back to 4.0.1 and i went on cydia to save my shsh blobs. The only problem is that cydia is saving the shsh blobs of 4.1 and I never had 4.1 on this phone. I tried using tinyumbrella but it is having the same issues also. I just want to do a full restore for 4.0.1 for my iphone. Should i use a custom firmware to update to 4.1? or is there an update to 4.1 i can do and preserve my baseband for unlocking? I NEED HELP GUYS!!! thanks again. X

    I had almost the similar situation which you have. I have 3GS with old bootrom, had 4.0.1 JB using jailbreakme. Then I was playing around after 4.1 one was out and I bricked it, so I had to upgrade to 4.1 to make it up and running. Waited for 2 weeks to get GreenPoison but it was not out, so I downgraded back to 4.0.1, then followed the steps on this to use custom firmware with Snowbreeze to get on 4.1

    Just make sure that you follow each step very carefully and take full backup before starting anything.
    I have my 3GS running perfectly on 4.1 JB

    I believe with the custom firmware upgrade you preserve your baseband but I have never unlocked my phone so I wont be the best person to answer this. Make sure that you get some guidance before proceeding because thats something very important to you

    I have 5.14.02 since I had upgraded to 4.1 official firmware once but I have old bootrom 3GS. Use f0recast to check your compatibility

    I have assessed the details of your iphone and this is what i conclude :
    You cannot use custom firmware and you cannot restore to 4.0.1. In other words, you cannot do any restore, if your iphone crashes, then you can only restore to 4.1 and you will lose your jailbreak and unlock too.

    If you don't believe me, you can ask another expert for another opinion.

    After the install, i will guide you on custom firmware.

    and don't install any other cydia stuffs to avoid crashes.
