iPad stuck at app,e logo

I hope someone can help. I have an iPad 3 running 5.1.1 untethered jailbreak. All has been fine.today installed mywi and then rebooted... Now I am stuck at apple logo. If I boot while holding the volume up key, the system boots. I did that and uninstalled mywi .. However I still can not get a normal boot. I was going to give up and do a restore but it want to restore to ios 6 and I can't do that because no jailbreak untethered yet. How Can I fix this. If volume up lets it boot,it must be a tweek became corrupted when mywi was installed. Any help would be appreciated.....
