Pangu Untether updated to fix overheating issues on 32-bit devices

If you’ve jailbroken your iPhone 5, iPod touch 5th gen, iPhone 4s, iPad 2, or any other 32-bit iOS device, then perhaps you’ve encountered the problem that this update fixes.

The launchd process would “spin” continuously burning CPU and battery, and in some cases, even making the device run extremely hot.

Head over Cydia now to find the Untether update. Once you install it, you’ll need to reboot your device.

Here is the full change log for the update:

Version 0.3 of this package fixes the issue where, on 32-bit devices (iPod 5, iPhone 4S/5, iPad 2, iPad Mini 1) a specific background process (launchd) would sometimes “spin”, burning CPU and battery, or even heating up.

Even if you’re running a 64-bit device or haven’t experienced issues on your 32-bit device, it’s still recommended that you update. Be sure to save any work before you update, because as stated, the update does require a reboot.

This package has been pulled by Saurik for the following reasons. Saurik on /r/jailbreak:

Some users on 64-bit devices are reporting mild to serious issues with this package. According to the Pangu team, they have changed almost nothing on 64-bit, and have not seen the issue themselves in their testing. We have pulled the package anyway, and the people at Pangu are working on doing a more detailed analysis of the issue.

After few hours package came back up

We’ve officially re-released Pangu 8.0-8.1 Untether update 0.3, which fixes the issue where, on 32-bit devices, launchd would sometimes “spin”, burning CPU and battery

For context, this is the update that we released about 10 hours ago and pulled because of reports of booting problems on a few devices. Please see the updated package description for how to avoid booting problems. If you follow these instructions, it should be safe to update this untether on all iOS 8 devices:

Note: before installing updates to this package (which will require a reboot), if, after the first time you ran Cydia on this device, you used the iTunes “restore from backup” feature (or otherwise used iTunes or iCloud to put old data back on your device), please now reinstall Cydia Installer (by going to that package and tapping Modify, Reinstall, and Confirm) to make sure your device can safely reboot with a passcode enabled.

The details about the contents of the untether update:

Version 0.3 of this package fixes the issue where, on 32-bit devices (iPod 5, iPhone 4S/5, iPad 2/3/4, iPad Mini 1) a specific background process (launchd) would sometimes “spin”, burning CPU and battery, or even heating up.

And a reminder about other potential types of booting problems:

Please also note that rebooting can surface other problems unrelated to the untether or Cydia. For example, having incompatible tweaks installed can cause problems upon rebooting.

You may have already installed this update earlier today. To check if you need this update, refresh Cydia and see if Cydia prompts you to install it.

(Much thanks to everyone who tested these instructions for this update to help determine that re-releasing this would be reasonable!)
