How to Jailbreak iOS 5.0.1 Untethered on iPhone with redsn0w 0.9.10b3


The following is an updated tutorial to assist you in achieving an untethered iOS 5.0.1 jailbreak for your iPhone, iPad, and iPod touch using redsn0w 0.9.10b3. The untethered jailbreak is currently for non-A5 devices only (will not work with iPhone 4S or iPad 2).

Warning: do not proceed if you’re unsure about what you’re doing. Follow the guide at your own risk.

Should I use PwnageTool or redsn0w to jailbreak?

PwnageTool enables you to create a custom IPSW to update to iOS 5.0.1 in iTunes, so you can preserve your baseband. This is important if you use ultrasn0w to unlock your phone.

The latest version of redsn0w now includes options for creating a custom IPSW in the ‘Extras’ menu. If redsn0w doesn’t work, try PwnageTool to jailbreak instead.

This guide will help you jailbreak your iOS device on a Mac

Before we begin: sync/backup your data via iCloud or in iTunes.

Step 1: Download redsn0w 0.9.10b3 and save it to your desktop.

Step 2: If you’re not on iOS 5.0.1, restore or update to the latest iOS in iTunes. If you’re already on iOS 5.0.1, skip this step.

Step 3: Launch redsn0w and click ‘Jailbreak’:

Step 4: Turn off your device and ensure it is plugged into your Mac. You are preparing to enter ‘DFU mode’ in the next step so redsn0w can jailbreak your device:

Step 5: Follow the instructions for DFU mode, as it counts down the seconds for you.

If you fail, start the process again.

Step 6: If successful entering DFU mode, you’ll see this screen as redsn0w prepares jailbreak data for your iPhone:

Once you see the screen below, ensure Cydia is ticked off, and click ‘Next’:

Step 7: redsn0w will now work its magic and jailbreak your iPhone. You’ll see a black screen with lots of tiny white text on your iPhone. Just let it complete.

If you see the pineapple everything is going as planned:

Step 8. When complete, you should see Cydia on your Homescreen. Voila!

If you run into iBooks not loading, follow these steps on how to fix it.

Let me know how this tutorial works for you!

    I jailbroke my iPhone 4 on 5.01 using version b2 of redsn0w. It’s working fine. Do I need to redo the process using b3?

    I’m hoping someone can answer this question.
    I jailbroke my device with the new Redsnow tool without updating to 5.01
    Jailbroke on 5.0 and the jailbreak is tethered. I now find that I cannot update to 5.0.1 through the over the air update.

    Have I totally screwed up or will an update through the computer and iTunes solve my problem to update to 5.0.1?

  • Update through iTunes to 5.0.1 then jailbreak untethered with redsn0w.

  • Nick

    Still no 4s or ipad2 right?

  • Correct. Pod2g working on the A5 jailbreak as we speak.

  • Ecua3000

    Thank you. I was worried that using the wrong jailbreak tool would have ruined my official update options.

    I have an iPod touch 4, jailbroken by jailbreakme. I’d really like to upgrade to ios 5.0.1 and jailbreak again, but what are the measures I need to take beforehand? I really don’t want to lose everything I’ve acquired during my jailbreak including the Cydia apps and their settings. How do I save them and how do I restore them after jailbreaking?

    I’ve tried googling before asking this question, but there’s a lot of varied information about past jailbreaks and I would really love a straightforward, comprehensive guide, if it’s out there somewhere. Maybe I’m using the wrong search terms.

    I would appreciate any help! Thanks!

    I’ve jailbroken my iPhone 4 using redsn0w. Everything worked fine, but when I try to install anything on cydia it won’t download. The download will just stay on the black screen and not do anything. Any suggestions?

  • I would restore and re-jailbreak with redsn0w. Sometimes these things fix themselves after another restore. Worth a shot.

  • Anon

    Doesn’t work for me either.  I get errors.

  • Rolando

    I already made the jail braking and it works perfectly, but i still have a game console, because i cannot use it like phone.
     If someone of you know how to do it, please, share with many people that are waiting for.

  • Your baseband does not have an unlock yet. Only 01.59.00 baseband can be unlocked with ultrasn0w.

  • Online business has seen a tremendous growth in the recent years. More and more people are attracted towards business online. Online business can fetch you lots of money as they are well paid. If done in a proper way. There are numerous online businesses available but to be successful you have to do business in a proper way or you would be a loser at the end. My one of friend is doing work at internet and last month his account is credited with 8000 USD. Just go here for more details?
