iPad HELP ran evasion for three days random crash. stuck in boot loop.

try booting up in safe mode by holding vol up + power. And if you restore your device, you will lose you jb btw.

 

as said by the previous user, while it is booting up, holding the volume up key. If you are able to gain access to your phone, go into cydia and uninstall this new keyboard you installed

 

hold the home and power button until your device shuts off. afterwards, press the power button and hold the volume up button at the same time. once you see the apple logo, let go of the power button but continue holding the volume up button until it gets to your lock screen. If it's been 1-2 minutes at the apple logo while holding the volume up button, that's way too long

are you still stuck at the apple logo?

edit: btw, what idevice are you on?

 

Do you happen to remember when you installed that keyboard, did it require you to install MobileSubstrate? Or did you already have MobileSubstrate installed?

 

that's strange, you should be able to boot up in safe mode if it's a winterboard theme

btw, winterboard causes a respring, not a reboot so how did you get to that apple logo in the first place?

 

if trying to boot up in safe mode by holding that volume up key does not work, then your only resort would be to restore

if you are ready to give up the jailbreak, then you can restore by putting your ipad into DFU mode

 

if you are stuck at the apple logo, i don't think you can restore from a backup because itunes won't recognize it in a usable state. it'll just say that it has detected your device in recovery mode.

restoring from a backup will not force an update

edit: this might help you remove the passcode: http://www.ifans.com/forums/threads/lost-password-how-to-reset-with-ssh.245764/

use iFunBox to connect to your ipad file system (SSH is not an option since you need to be connected to the wifi network to use that)

you could try googling before you actually perform the steps to remove the passcode just to make sure it is the right steps

 

I don't think restoring from backup will allow you to get to springboard

Btw, I checked our black keyboard and it said "NOT COMPATIBLE WITH IOS5" in the description and if you look at the release date, it was in the year 2011 which meant that it was meant for iOS 4

Next time, be careful with what you install. Disabling mobile substrate should have done the job by means since themes using winterboard rely on mobile substrate. Really strange it did not

It's a shame you weren't able to get your jailbreak back

Maybe holding the power and home button to reboot could mimic rebooting?

Edit: just noticed you restored . I think the next jailbreak will come out in 9-12 months if iOS 7 is released in the summer
