So here is my problem:

I wanted to update my iPad to iOS 6 but it makes error. Then I knew it was from the jailbreak, so I tried to format it from settings, but first it just freezed, then I turn it off then on again then I tried again, same freeze BUT THIS TIME, when I restarted my iPad and slide to unlock, it turned to safe mode. I respringed a lot of times but, same error. So I use safe mode at the moment but I can't use almost all tweaks or just cant modify any. So I know the answer will come with a PC but, I don't have PC at the moment and I remember that this happens in 5.1 and I was having PC but somehow I don't remember I fixed it without PC so please help.

Edit: Uninstalling tweaks and hacks makes no use.

Get TinyUmbrella, connect your iPad, untick "Set Host to Cydia". Download the iOS 6 IPSW for your iPad, put your iPad into DFU, go to iTunes, shift+click Restore, select the stock iOS 6 IPSW and wait.

First from where should I get tiny umbrella? Cydia? Safari? Second be a little illustrative if it means what I mean.

Unfortunately, if your iPad is jail broken, you must use iTunes and a PC (or Mac) to upgrade to iOS 6. You can't do the over-the-air (OTA) install with a jail broken iPad.

And - there is no other way. Sorry.

It's ok I just wana get out of safe mode some how so anyway?

To get the iPad out of Safe Mode, just reset it. To do:

Hold both the power and home buttons until the screen goes dark and the Apple logo then appears (the slide to unlock screen may or may not appear). Once the logo appears, release the buttons. After a time, your homescreen will appear. Please note that it may take some time for the Apple logo to appear or for your homescreen to appear (or both). This is normal. Eventually, the homescreen will appear.

That should bring it back to "normal."

Have you seen this tutorial? If followed exactly, it will result in a functional iPad running the current version of iOS. In this case, iOS 6.

Nice but I don't have PC, remember? So I can't do even a single thing without a PC. Man, I think this is it...

Having a jailbroken device without access to a PC is not the best idea in the world

You cannot ever update or restore a jailbroken iPad without access to a PC, just like you cannot jailbreak and iPad2 or iPad3 it in the first place without one. They are pretty essential.

Your best bet is to borrow someone else's PC for 30 minutes. All they need is the latest iTunes installed. Nothing else. You won't mess up their setup in any way if you follow the guide posted above.
