Redns0w 0.9.10b3 Released to Fix MobileSubstrate Based Jailbreak Apps Issues

The iPhone Dev-Team has released yet another update for the RedSn0w 0.9.10b3, the untethered iOS 5.0.1 jailbreak. Redns0w 0.9.10b3 fixes issues with MobileSubstrate based jailbreak apps, reported by many users who used RedSn0w 0.9.10b2 which was pushed to fix the launchctl error.

iPhone Dev team has posted the following details about the Redns0w 0.9.10b3 on their blog:

The b3 version of redsn0w fixes a problem where re-running redsn0w over an existing jailbreak would cause MobileSubstrate-based apps to stop running until MS was installed again. Now you can re-run the redsn0w jailbreak step without worrying about that (but still remember to de-select the “Install Cydia” option if it’s already installed).

Dev-Team has also added a tip:

TIP: If auto-detection fails and redsn0w tells you no identifying data was found, you can always pre-select the appropriate 5.0.1 IPSW using “Extras->Select IPSW”.

Redns0w 0.9.10b3 and iOS 5.0.1 dwnload links alogn with the detailed RedSn0w guide are available below…

Update: Download RedSn0w 0.9.10b5

Update 2: Download RedSn0w 0.9.10b5c

You need to run task manager (CTL-ALT-DEL) then kill any iTunes products AND TuneUpUtilities then re-run the RedSn0w. The TuneUpUtilites was the culprit in my case.

people who are having error while uploading first stage, boot your iphone to recovery mode first then boot to dfu mode from there.

DJYT January 13, 2012, 1:12 am

Same Here on Windows iphone 3gs, just restore to 5.0.1 and when the iphone goes into dfu i get the error at “uploading first stage”, any help?

MiniTux February 3, 2012, 2:11 am

HELP!!! Stuck in recovery mode!!!

Attempted DFU Mode and after the status bar was complete on the “Uploading First Stage” step, I get an error that reads: redsn0w.exe has encountered a problem and needs to close. Then it crashes. When I attempt again, it either does the same thing, or redsn0w says “USB communication error”. Yes, I have tried different USB ports and No, I’m not using any sort of hub. I have also tried manually selecting the ISPW before I began the Jailbreak.

Redsn0w 0.9.10b5
iPhone 4
iOS 5.0.1
Windows XP

If you need any other information, just let me know and I’ll be happy to provide.
