i get through the jb process fine but when i try to reboot just tethered it looks like its working then just hangs at uploading kernal and the pineapple on the ipad and it just sits there then eventully reboots and cydia doesnt work so idk what im doing wrong must have tried it 15 to 20 times!!! any help is awesome thank you

Hi..what is the meaning of ..."You will only be able to perform a tethered jailbreak at this time. This means you will need Redsn0w's assistance to boot into your jailbroken device. If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.

It means that anytime the device is powered off (hold the power button down and slide to shut off), you will need Red Snow to get it running again. If you're not comfortable with this, don't do it and wait for a non tethered version someday

I get stuck on the "Uploading ramdisk" portion of the JB. My iPad shows "Downloading Jailbreak Data..." but stays like that for a long time. I've tried multiple times running RedSn0w as an administrator and in XP SP3 compatibility mode to no avail. Not sure what I'm doing wrong, but I guess I'll soon try another computer. Any ideas?
Chris
Chris - December 13, 2010 at 11:02pm
Well, I just tried for the last time using XP SP3 compatibilty AND "run as administrator" from my Windows 7 PC. Looks like it worked PERFECTLY. I can't wait to unleash the power of this device!

I also had the same problem. I am on Win 7/64. I tried everything, including run as admin, doing it form the admin account, I even tried it on my WIndows XP 32 partition. IT never worked. I finally stumbled on a thread that said it had somethign to do with processor affinity settings on MP or Multi-Core systems. I started redsn0w, then opened Task Manager. FInd the redsn0w process and right click, go to Affinity and uncheck Processor 0. If you get access denied, make sure you are admin and that you have show processes from all users checked. Once the affinity setting is changed, then go back to redsn0w and keep going as instructed. Worked the first time after dozens if not scores of tries previously for me.

I also encountered the same problem on my Windows 7, but I tried running it as administrator and it got through. But my cydia is unable to start.

I jail broke the iPad, installed few apps throughout installous and Cydia, was very happy, then Cydia had few updates, I did, next it went to reboot, and never came back to life, stayed on the apple logo for the whole day, a tried rebooting manually over 10 times and still same luck...hook it up to iTunes and it won't detect iPad, tried few times .. Battery dies, recharged it and took it to the apple store,, the guy there hooked it to a special software to restore the iPad, without iTunes detect. Glad to have back and but not jail broken yet, waiting maybe for a fix... Apple store guy didn't ask too much questions.. I told him after I installed the the version of the 4.2.1, this crash happened.. Service, free..

Hi I was able to JB Ipad on latest FW and run Cydia, and install all required packages for it, but my problem is that after I install SBsettings I'm asked to Reboot Device but when it reboot it gets stock on the Apple logo. Anyone else having the same problem or know how to resolve it? Thanks
Eddie
Eddie - December 4, 2010 at 3:35am
After I jail broke the iPad , installed few apps, then sbsettings, and reboot. IPad wouldn't come back, had the apple logo all night, the batteries died out . Next they recharged it with still apple logo on.. Problem, it wouldn't even detect the iTunes so I would restore... Had to take it back to apple store,, the genius bar, hooked it up to his laptop and had to do something special because it wouldn't detect itunes at the store too.. Finally the iPad started to restore by itself throughout the laptop but with no iTunes on or detected... Thankfully, iPad is up but haven't jail broke again, still waiting for fixes....
Paul
Paul - December 4, 2010 at 8:19am
Hi In my case what I did after the new jailbreak is when Cydia asked to Reboot don't click on the Reboot but do Switch Off on the ipad, after hoocked it to laptop, open Resn0w, selected the "Jut Boot tethered right now" and was able to start the ipad. All working ok since them. What the probably did in the shop to manage to get the laptop to detect it was start the Ipad in DFU mode.

TheCoose - December 28, 2010 at 3:00pm
Um, this is a tethered JB. if you reboot the iPad, you need to have it hooked up to and resteart using the redsnow and the ispw. if you don't know what i'm talking about, you are best of to wait until a non-tethered JB is released.

Update 1 : Windows 7 or Vista users often need to use XP or 98 compatibility modes when launching redsn0w (right-click)

do the last step under "Important Note:" run redsnow again and check the box "just boot tethered right now" and go from there

Cydia does not work after jailbreaking.
Bryan
Bryan - November 24, 2010 at 1:44am
Same for me, i tried booting back but redsn0w just stops working.
jipad
jipad - November 24, 2010 at 1:57am
i don't know the reason too, i have to try do it many time even restore the firmware and do the jailbreak from stretch but the cydia still does not work... may be because the cydia does not work that's why i don't need to jailbreak again after rebooting my ipad.
jipad
jipad - November 24, 2010 at 2:56am
i got it working now. you need to re-jailbreak again but select the "Just boot tethered right now"
