First person to fix my iPhone that's stuck in a boot loop gets 0.1BTC

[cheesylard]

It's a 16GB iPhone 4S running iOS 6.0.0. I want to preserve the jailbreak, so any advice that has anything to do with restoring it to factory settings will be ignored.

Syslog is here: http://pastebin.com/raw.php?i=LxswTx6k

List of currently installed packages is here: http://pastebin.com/raw.php?i=PjxUrvc7

As you can see by the syslog, the phone is only on for about 2 minutes before turning off and back on again. This started happening when I uninstalled a couple packages

Let me know if you need anything else.

I already tried ilex r.a.t, by the way.

I'm pretty sure that's caused by these:

If you can open the iphone files system in iPhone Explorer, delete the following:

root-Applications-MobileMail.app-MailEnhancer_ToggleUnread.png & MailEnhancer_ToggleUnread@2x.png (delete xxx.png files)

root-Library-MobileSubstrate-DynamicLibraries-MailEnhancer.dylib & MailEnhancer.plist (delete xxx.dylib and xxx.plist files)

root-Library-MobileSubstrate-PreferenceBundles-MailEnhancer.bundle (delete the whole folder 'MailEnhancer.bundle)

root-Library-MobileSubstrate-PreferenceLoader-Preferences-MailEnhancer.plist (delete xxx.plist file)

try that, it seems Springboard is causing the issue (from my limited iOS knowledge)

None of those are in my filesystem.

Well apparently your system is looking for Springboard & it's not installed, which seems to be the issue (guess you removed something too much?)

I want to preserve the jailbreak.

[Welsh]

Plug your Iphone into your computer, launch up Itunes. Then cancel sync, wait to see if it automatically boots otherwise enter recovery mode, you could also enter DFU mode.


I have had this problem no ends of times after jailbreaking and this always sorts it out.

Grip iPhone tight. Launch onto concrete. Buy android.

Fixed.

Should be able to put it in dfu mode and restore the the firmware that was on there before jailbreaking. After you restore the firmware jailbreak again. Also you could just put it in dfu mode and rerun the jailbreak. Also check for  updated jailbreak software.

This updates to 6.1.3, which is not jailbreakable.

I would, but there's more money in iOS development so I put up with it. Honestly when you get it working right, jailbroken iOS > Android

And how's that working out for you?

[rethaw]

Do you have SHSH blobs for any other software versions?

EDIT: I've had some success using iFaith to get the signed blobs off the device, but it seems like you aren't going to be able to do that from your description.

When it's booting up, simultaneously keep the Volume Up button pressed and you should be able to see your Lock screen again. Launch Cydia and scroll to the top of the list in the Changes tab, update Mobile Substrate.
