    Default Huge problems upgrading to iOS4, Might Brick iPhone, Please Help
    Hi everyone,

    I have a 32GB 3Gs running 3.1.2 (old bootrom, jailbroken with pwnage tool like 4 months ago) and wanted to upgrade to iOS4 last night. I built the ipsw in pwnage tool, and put the phone into dfu mode. I got the 1600 error, and kept trying to alt+restore, but the error kept coming up. I then put the phone in recovery mode, and tried alt+restoring, but I started getting the 1611 error. I tried for several hours last night to make it work, but that error kept coming back.

    I read through the forums that one way that I could try getting it to work would be by restarting my computer and putting it into DFU at the same time. Everything actually seemed to work, the process would finally go for longer than a minute. The problem is that the process is still running, and it has been since midnight. Since then it has still been like 1 mm away from being fully restored. All iTunes says is "Restoring iPhone Software" with the bar almost full as well.

    I need your help, I'm extremely afraid of bricking my iphone. What can I do?

    Thanks MMi

    I just got home, and it still in the same position as before. iTunes claims it's still restoring the phone. This can't be possible, as it's been 16 hours already. Any suggestions? I don't want to brick my phone...

    There's still no reply from someone experienced, and I haven't been in this situation so I can't really give you advice.

    In any case, as far as I can remember, if anything goes wrong with the restore/update process, you can most probably try doing it again without bricking the phone, but as I said, there are no guarantees for this.

    P.S. I searched around forums, and the problem may be happening due to some app installed on your computer or phone - check if you have "Wifi Sync" installed, and if so, uninstall it. If that also doesn't help, try reinstalling iTunes so you clear it's download cache (chances are yesterday a lot of people were trying to download iOS4, so you may have downloaded a corrupt copy due to a lack of server bandwidth).

    I finally fixed it btw. Thanks for your help. I ended up doing a bunch of stuff. Firstly, I deleted everything iTunes related on my laptop, then restarted, switched usb ports, built a new ipsw with pwnage tool, and finally restored. Thanks again

    You messed up in the first place. If you are going from jailbroken 3.1.2 to jailbroken 4.0 you don't use DFU... Pwnage tool specifically tells you to use /recovery/ if you are already pwned... this allows it to upload the JB payload first.. then it reboots back into recovery mode.. then you option+click restore to the custom IPSW.
