Just don't turn it off. Let it go to sleep mode when not using and keep it on charger over night.

I've done the jailbreak twice and each time I get a white cydia app that won't open and safari that will not work either. Please Help! Thanks.

When you say you did the jailbreak twice, did you first run it saying to install Cydia and the 2nd time to Tether Only? If you did it this way then the white icon should be the normal brown Cydia icon and it should load fine. If this fixes your problem then in the future if your iPad reboots itself then you only need to run the Tether Only option to reactivate the jailbreak.

I've jailbroken many an iDevice over the last few years. For some reason my iPad will not shut off so I can run Redsn0w. After holding the power button on top and swiping the "slide to power off" button my iPad immediately reboots itself and does not stay off. I am baffled - any advice would be appreciated.

dont worry about ipad, run redsnow, choose boot tethered now, follow instructions, it will work. try to countdown seconds yourself, just to be correct.

you have to transfer purchases from ipad or they will be removed, find it on your own.

why does the 3G connection not work after jailbreak? is there an unlock neccessary?? please help! :(

Thanks. Works. But Tethered Reboot is a big problem longer term. The instructions didn't really make it 100% clear that EVERY time you reboot the iPad you have to now Jailbreak it after following the above. But like I said, thanks, I appreciate the efforts very much and hope a breakthrough from this tethered reboot pans out.

My 3G network was unable to detect after I had switch off my airplane mode and I had to boot to Tethered mode to get the network back. Can anyone help? Thanks

So what happens to all the apps i bought from iTunes if i JB my iPad? will all be lost? and i will have to pay for the Business apps that i really need and use daily. Or are you supposed to JB as soon as you get the iPad before buying needed apps?

criminal record - December 4, 2010 at 1:37pm
you still have them, no worries.

Following these directions, along with the ones in the comments, I am able to jb, but as soon as I try to sync all my cracked apps after installous, I get stuck at the apple logo, and then I have to do a full restore. This jailbreak is not the best.

when stuck at the apple logo, simply use redsnow again and boot tethered!

Need help! I just did step by step but the iPad freeze just before the white bar gets the final point, I tried this 4 times and the result is the same. And iTunes does not send any message. Any idea on what is going on?
dyohanan
dyohanan - November 29, 2010 at 10:26am
I just connect my other iPad and start working for the stuck iPad, so this issue is fixed, now the problem is that safari and cydia do not work at all. I saw many comments with the same problem, any idea?
dyohanan
dyohanan - November 29, 2010 at 10:34am
Me again, I just run redsnow again and told it to just reboot tethered and safari and cydia start working again, so every time we do a software installation that needs to reboot we need to reboot it again with redsnow.

sparcus - November 29, 2010 at 4:04am
works! thanks a lot!

terry - November 26, 2010 at 12:21am
Hi Folks: I read elsewhere the problem is currently Cydia, which does not work currently. When installed it affects other apps SUCH AS SAFARI. I'm going to try the jailbreak again without Cydia and see if Safari works. Hope this helps until Cydia gets updated. Happy Thanks,

guizmo - November 26, 2010 at 1:34pm
Hey guys the next step is very important to solve the issues with Safari and no Cydia. Run the RedSnOw again but only using "Just boot tethered right now"
Sparky
Sparky - November 27, 2010 at 1:10pm
The tutorial is missing a few steps at the end. You will see a white Cydia icon. You need to redo the first few steps but select BOOT TETHERED first.
patty
patty - November 28, 2010 at 11:17am
to make cydia work, you need to go through redsn0w again and check the box for Just boot tethered right now from the options window and click Next.
timmy
timmy - November 25, 2010 at 1:28pm
same thing here, neither cydia nor safari works. followed directions twice, same outcome. feedback please?

Had the same Cydia problem. As well, Safari does not work. Appears briefly then disappears.

someone - November 24, 2010 at 1:58am
redo jailbreak with an option "just reboot tethered right now" then everything works
carlos
carlos - November 25, 2010 at 11:36pm
Yes I re-did the same with the thetering option and it worked cydia icon and safari now!!, greetings from El Salvador

i have tried but after jailbreaking my ipad, the cydia does not work. the icon of cydia is just white.
Aric
Aric - November 24, 2010 at 11:37am
Same problem here. I fixed it by turning the iPad of, running Redsnow with 'just boot tethered right now' ticked. Only problem is now iTunes doesn't recognise the iPad and I can't sync anything across.

Jeffrey26 - November 24, 2010 at 12:32pm
I had the same problem. If you go back to redsn0w and run it again but without to check the cydia install option you will found the new logo on start up and cydia will then work.
