    Hello Friends,

    This is my first post here, i have found these forums to be extremely informational and helpful.

    I Have a Jail-broken iPhone 5 Running 6.1

    Everything was fine, until this morning. I woke up and saw that there was no carrier signal, so i rebooted the device. This is when it all started.

    My iPhone went in to a boot loop and it started flashing the apple logo over and over again. I was able to enter the recovery mode (connected to PC while keeping the home button pressed) and the iTunes logo appeared. Tunes displayed a message that the phone needs to be restored and it started downloading the latest firmware (6.1.3). I knew i will loose the jailbreak but i wanted to get my phone up and running so i went with it. Once the file was downloaded, it started the restore process, verified it with apple and once the phone rebooted it gave me an unknown error 21.

    I googled about it and most of the results pointed towards putting the device into DFU mode.

    Now in the DFU mode, i have encountered 2 different scenarios.

    A. If I enter the DFU mode from the recovery screen (the iPhone is displaying iTunes Logo) iTunes start the recovery process, validates everything and during the process the iPhone reboots, the recovery screen(iTunes logo) comes and I get the error 21.

    B. If i enter the DFU mode from the apple loop, iTunes start the restore process, the iPhone reboots. after the reboot, the phone goes back to the apple logo loop and the iTunes displays that it is validating the restore for a long time and then give me the 1602 error.

    I also read somewhere that the Error has some thing to do with Tiny umbrella. I have modified the setting in tiny umbrella and modified the hosts fine but nothing seems to be working.

    As a last resort i shifted to a different computer(i have never used any iPhone with it) installed the latest iTunes but i get the same results. Then i read somewhere that disconnecting and reconnecting the battery also fixes it. I am not keen to do that i have no experience with hardware and i am not sure i will be able to do it.

    Please help me, this is my first iPhone and i have spent all my day looking for a solution but i cant seem to fine one.

    If i cant fix it and have to give it in for repairs, will Apple find it that my phone was jail-broken. If yes, they might not fix it or charge me a fortune to fix it.

    Thanks in advance,

    Shamps.

    Are you entering into DFU mode properly? The screen should be completely black; it shouldn't be showing an iTunes logo. When in DFU mode, iTunes will say it has detected your phone into recovery mode but your screen will be black. If it's not black, you did not enter DFU mode

    Yes, I enter the DFU mode correctly. The screen is totally blank and itunes detect an iphone in recovery mode. I am 100 % sure about this.

    Then there are 2 results as i mentioned in the OP depending from where i enter the DFU mode.

    Hey Mate.

    If you dont mind telling me, what did you do to finally get around it? I tried 100 of times today on 2 different computers but no avail.

    You were also stuck in the apple logo boot loop?

    Any tips will be greatly appreciated.

    Cheers!!

    Any apple store around your area, why don't you take it in and replace it, very likely the refurblish one still have v6.1.2 on it and you can JB it.

    I dont mind giving it in for repair. Since it is not booting up and i am jailbroken, will apple find out that i have jail broken. I cant do anything about it atm and i will have to hand it in like it is.


    I need to absolutely sure that they will not know about it being jailbroken before giving it in. Any insight on this?

    Cheers!!

    They restore the phone the same way we do here, DFU mode or recovery mode, and I don't think they will bother to get it fix, they will just hand you a refurblish one.

    I hope it is the case. I think i will try again on a 3rd computer tomorrow at a friend's place.

    You just kept trying and trying and it went through? Did you change anything? Any tips might save me giving it in for repairs.

    I will try tomorrow again.

    Any inputs from other users.

    Is it certain that since the phone is not booting up, apple service will not find about it being jailbroken. I am asking again because i dont want to regret it later.

    Cheers!!

    I just tried. I tried powering it up holding the volume up button. It just keeps going into the recovery mode(iTunes logo). Have tried 6-7 times but it just simply wont boot.

    What to do?

    Cheers!!

    Error 21 is indicating the phone not in DFU.

    To properly go in to DFU:
    Connect USB
    Hold home and power until phone turns off
    Keep holding both for another 3 seconds
    Now release power while holding home for another 10 seconds.
    Phone should bevin DFU now

    I am able to put the phone in DFU mode, i am sure because the screen is totally black and itunes detect a phone in recovery mode. I follow the above steps exactly as you mentioned.

    Now as I mentioned in the OP, two things happen depending on from where I enter the DFU mode.

    If.i activate the DFU mode from the apple logo boot loop. Itunes detect it, it starts the restore process and after validation, during the restore, the iphone reboots. After rebooting, the iphone again goes into the apple logo loop and after a while a get Error 1602.

    if I activate the DFU mode frome the recovery screen (itunes logo), the iphone goes into DFU mode, itunes detect a phone in recovery mode. Then the restore process starts and after validation and usual stuff, the iphone reboots. After rebooting, the recovery screen appears and i get error 21.

    It seems that during the restore process, the iphone reboots back to the state from which it entered the DFU mode and the restore process in interrupted.

    Since i can put the phone into 2 states only, either the apple logo boot or the recovery screen, i dnot know what else to do.

    Cheers!!

    Did you ever change your host file so it points to Cydia, because that is the 1602 error.

    I did modify the hosts file on my laptop, i deleted the 2 entries regarding apple server because i read somewhere that these entries are there because of tiny umbrella and these are causing the error21.

    But on my PC i never installed tiny umbrella and it was the first time i connected my iphone. InfAct I installed itunes for the first time on it todays so J am 100 % sure that the hosts file on my PC is untouched. Still i get these same errors on the PC as well as my laptop.

    Cheers!!

    You can try typing gs.apple.com in your browser, it should take you to an Apple placeholder page.

    Error 21 is not in DFU mode
    1602 is usually a hist problem

    I just typed gs.apple.com into my browser on my laptop and it took me to a placeholder page.

    Does that mean anything.

    As I said earlier, the error depends on the state from which the DFU mode is actiavated.

    Apple boot loop - DFU - Restore - Error 1602
    Recovery screen - DFU - Restore - Error 21

    I appreciate your help and the your time, Any ideas what to do next??

    cheers!!

    Yeah, i have tried everything mentioned here.

    Any other ideas?

    The only thing i have on my mind is to try restoring on my friends PC tomorrow. He has never used itunes ir owned an iphone. So i am hoping that it might make a difference.

    BTW, if nothing works and I give in my iphone to apple for repairs, can they find out if it was jailbroken? I am sure if it was to boot it would have by now and restoring will wipe all traces of JB. I just want ti be sure before i hand it in.

    Cheers!!

    If it won't boot they can't see, if it still under warranty you get an exchange.

    Its just 2 months old. It just simply wont boot. Not even in safe mode. I am sure there is no other alternative way to boot it ( i am hoping not).

    I think i dont have any other option than to give it in. Thanks for your help mate. Highly appreciated. Do mention if simething is left to be tried.

    Cheers!!
