    Hello,

    I am happy to find this active forum. Here is my problem below, can someone please please help me URGENTLY:

    I have an iPhone 3GS and it has the software version of 3.1.2. I bought this 6+ months ago and then I used Blackra1n to jailbreak it and also unlock it. Everything went well and it did not give me a problem for a while until now.

    Now, all of a sudden the iPhone froze once while I was simply using it and when I held the home button and the top-right button, I restarted it (hoping it will take me back to the passcode entrance screen), but the iPhone gets stuck at the Apple logo and restarts over and over again (looping!). I cannot get passed the Apple logo. The Apple logo just stays there and then the loading circle appears and then after some minutes, it restarts again and does the same thing. It's very frustrating!

    Now I can go into Recovery Mode and restore it and update it to iOS 4 (which I planned to in the future), but I NEVER BACKED-UP my data!!!

    ***I really need to backup my data before I can do a Restore.***


    Can someone please help???????????

    Please reply ASAP. I am very frustrated as I cannot use it and the data in it is very important.


    Also see the following links. Should I do the procedures they are talking about to stop the restarting over and over again?

    I just want my phone to go back to the main screen after i input my passcode so that I can backup all my stuff and restore my iPhone to iOS4 and remove the jailbreak!

    Please Please help. Please reply and give me some sort of Advice.

    THANK YOU!!!!

    You are going to have to restore the phone, there's no way to get it to boot up without restoring via iTunes.

    I will need to get into DFU mode in order to install custom firmware correct? If so, which custom firmware version should I install (v3.1.2, which I had before?)

    Once I do that, will all my data remain on the iPhone? If so, then I will want to back it all up in iTunes and then put the latest iOS4 on it.

    I just need the data from my phone. Backing up is crucial..

    Thank you very much for the response and please answer the above questions.

    Also did you see the following links. Should I do the procedures they are talking about to stop the restarting over and over again?

    If you are in that loop you will have to put your phone in DFU mode. Then open up iTunes and restore your phone to whatever version you want. You will not be able to get any of the info from your phone it will be erased when you restore.

    As for the links I would try the second one's procedure, that sounds like it could work and you can recover all your info on your phone.

    Hello,

    I will try the 2nd link later today and hope it works. But lets say it doesn't then I can try the DFU mode and do a restore. But what firmware should I restore to??

    Also, I was able to get into Recovery mode, and when I held SHIFT and pressed Restore button in iTunes, I was able to select a firmware file from my PC. But this will only upgrade a firmware since it is in Recovery mode and NOT in DFU mode, right??

    Lastly, lets say loosing the data is the last resort and I have to do this, then what will I exactly loose? (Calendar events, contacts, etc..), but what about the APPS I purchased via the App Store that were NEVER backed up to iTunes. Will I have to buy them again or what???

    thanks!
