[FIX] Stuck at Apple Boot Logo with Constant Reboot

This thread is a compilation and update of the following two threads linked below and is applicable to the version 2.1 firmware on the iPhone and iPod Touch 1G. This post does not include all of the aforementioned methods from previous threads, only the ones that have resulted in the more often achieved success. Additionally, as of version 2.2.X I have no longer been able to make these methods work with any reliable success though notably I've not had to resort to these for the most part anyway:

DUMMIES GUIDE: How To Fix An iPhod Stuck On Boot Logo W/O Restoring by The Joker

&

Kill Watchdog Process by P0150N0U5F15)-(


METHOD 1:

Developed by The Joker and those that posted in his thread, this can be done via WiFi or through using iPhone Browser (for Windows users only), or DiskAid (for Mac users)

Steps:

1. Turn iPod or iPhone off
2. Connect cable
3. Turn on iPod/iPhone
4. Listen for the connection sound
5. Attempt to SSH into your iPod/iPhone (may take several tries on WiFi and will depend on if it was activated before the boot logo issue began - otherwise use the iPhone Browser)
6. Go to /var/mobile/
7. Rename Applications to Applications2
8. Wait until your springboard pops up
9. Now rename Applications back and restart
10. Some apps may seem to be missing, but they're there. Just resync and check that the Applications Tab in iTunes has your apps all selected for upload - it will bring them back up on the Springboard after 'seemingly' reinstalling them.

PROBLEM: This method usually generates several extra megabytes of data. I haven't been able to figure out where, why, or how, but if you're like me and you've filled your iPod/iPhone to its memory's brim, this would be annoying. If you have the time and patience to, use METHOD 2.


METHOD 2:

This method was developed on the Hackint0sh forums, shown on these forums by P0150N0U5F15)-(, demonstrated on TUAW, and finally played with and modified by me some weeks ago to combine METHOD 1 with killing the watchdog process:

1. Turn iPod or iPhone off
2. Connect cable
3. Turn on iPod/iPhone
4. Listen for the connection sound
5. Attempt to SSH into your iPod/iPhone (may take several tries on WiFi and will depend on if it was activated before the boot logo issue began - otherwise use the iPhone Browser)
6. Go to /System/Library/SystemConfiguration/
7. Rename mobilewatchdog.bundle to mobilewatchdog.bundle2
8. Reboot your iPhone/iPod and wait until the Springboard shows (may take several minutes, and one reboot on its own power, just leave it alone, this method has not failed me)
9. Once at Springboard again, rename mobilewatchdog.bundle2 back to mobilewatchdog.bundle and reboot (otherwise it will restart on its own).
10. No apps will be missing, no additional memory will be lost in this method, all should return to normal.
