IPad – Jailbroken iPad stuck at boot screen and looping

ipadjailbreak

I have a jailbroken iPad 1 with iOS 4.2.1

  • I replaced hosts file under /etc/ and resprang
  • the iPad stuck at blank screen
  • I restarted by pressing both power and home key
  • Now the iPad is stucking and looping at apple logo booting screen

Currently,

  • I can access the file system using iPhoneBrowser 1.9.3 and
  • iTunes 10.2.1 recognizes the iPad.
  • WIFI interface seems to be up but SSH is not up

Now, I have replaced the modified hosts with original file.

Still the screen never reached the lock screen. I doubt it is file system error and in this circumstances how can I check my iPad for file system error? Is there a way?

update 1

  • still stuck (have left it run out of battery)
  • WiFi is not up.

  • SpringBoard Crash log state that 

    Reason:          Watchdog timeout: 5 crashes, 732.836304s since last successful ping   
Thermal Level:   -1    
Thermal Sensors: failed to load sensor values

update 2

  • upgrade to 4.3.3
  • restore with back-up data
  • all are working fine now

Best Answer

The obvious answer is to re-install the OS and then ssh in to run fsck.

Have you looked into a program like PhoneView that will let you mount iOS device as an external drive and use Disk Utility (if you have a Mac) or fsck? The FAQ for PhoneView has a windows software recommendation that does about the same things if you prefer that OS on the desktop.

(edit: I don't know of any free alternatives that mount the file system)
