    Hi, i recently jailbroken my ipad 4.2.1 using redsn0w. However, when I went out today, it ran out of battery, so i charged it when i reached home.

    It is now stuck with the apple logo, and won't boot up. I know i must use redsn0w to boot it, but i can't off the ipad for it to enter DFU mode. I tried using the home/lock button 10 sec, but it resets the ipad rather than turning it off.

    Can anyone please help get my ipad back up and running please?

    Thanks.

    Have you plugged it into the computer and used redsnow to boot it?

    While I didn't have it happen due to a battery drain, I did accidently boot my jb iPad and was stuck in the same place.

    I tried everything and was nearly ready to do a complete restore when I finally got it.

    I'm not sure what I did but I think it was this:

    I got the iPad to turn off.... soon as I plugged it in it came back on. But right at that moment I began the Redsn0w reboot procedure.

    Again, not sure exactly the sequence I used but you can do it... try and try again. You should NOT have to restore.

    Good luck!

    I had the same problem.
    You don't have to turn your iPad off. I tried that several times too.
    All you need to do is link it to your PC and follow the instructions of redsn0w. Just ignore the warning that you should turn it off.
    Your iPad will turn in DFU mode and redsn0w will succesfully boot it.
    Hope this helps.

    If you can't turn it off, just plug it in.

    Boot Tethered

    then just hold power+home for about 15 seconds.

    release power and hold home till the process is finished.

    Cydia works fine. It was down last night but that was Cydia's servers... couldn't access it on my iPhone either.

    Most Cydia apps are 4.2.1-friendly now too.

    Here's my prob. Once I run redsnow it's starts the JB and as it's loading the ramdisk a window pops up and says redsnow.exe has stopped working. Im running vista. I've deleted redsnow a few times thinking the file was corrupt and thats not it they all do the samething. Tried downloading it on IE and Safari and that didnt work. I've checked to see if ituneshelper was running and that wasn't it. So I'm stuck I have no clue why this isn't working any help would be highly appreciated.

    You need to run redsn0w in XP Compatibility mode when using Vista or Windows 7, otherwise it crashes...

    thanks Dannyboy 85 it worked for me. all others should follow the same.
    one advice for guys with 4.2.1 version......our greatest mistake was to upgrade to 4.2.1 from 4.1. lets give up jailbreaking till the unteathered jailbreak becomes available.

    There was no 4.1 for iPad. So it's either 4.2.1 or 3.2.2. .

    I honestly don't see the big deal with the iPad having a tethered jb right now. I have had it for weeks now... it has never needed a spontaneous reboot nor do has my iPad's battery every run down completely.

    Moreover, the tethered nature has nothing to do with the issue of needing to run redsn0w in compatibility mode.
