Earlier today we told you the PwnDevTeam released a new Jailbreaking tool called Ac1dSn0w. This Jailbreaking tool Ac1dSn0w 1.0 beta can Jailbreak the iPod Touch 4G, iPad (first-generation), iPhone 4 and iPhone 3GS. As this is a new Jailbreaking tool we are going to be providing a how to guide on using Ac1dSn0w to Jailbreak your iPhone 4/iPhone 3GS tethered or semi-tethered running iOS 5.0/iOS 5.0.1 with Ac1dSn0w 1.0 beta.

1. Restoring Iphone In Dfu Mode

How To Jailbreak With Ac1dSn0w

1. Windows: Once your iPhone 4 is in pwned DFU mode, simply start iTunes and shift-click the restore button. Select the signed IPSW and it should work. OS X: Once your iPhone 4 is in pwned DFU mode, simply start iTunes and alt-click the restore button. Select the signed IPSW and it should work. Note: This step cannot be performed in VMWare.
2. So running Limera1n for example on an iPhone 4 in DFU mode loads a hacked iBoot bootrom in place which is just called Pwned DFU mode which disables regular iBoots desire to check for downgraded and such so that you can downgrade (with blobs), downgrade to tethered iOS versions jailbroken or not jailbroken without blobs (this is a fairly recent discovery), use custom IPSW files to restore from, etc.
3. According to him, Apple has already patched the bug on the newer devices last year, such as iPhone XS, iPhone XR, and iPhone XS MAX, so this works only on older devices like iPhone X, iPhone 7, and o son. In this video, I will show you to use the exploit to put the device in PWNED DFU MODE for a CFW Restore or for a Tethered Jailbreak.
4. By now ur ipod should be in pwned dfu mode and tiny umbrella should be running, now open itunes and hold shift restore and find the where u downloaded or put apples 4.3.5 ipsw then click it and itunes should ask u that u want to restore to 4.3.5 click yes and the process should run smoothly without any errors and ur ipod should turn back to.

Step 1: The first thing you will need to do is download Ac1dSn0w 1.0 beta from the iJailbreak Downloads Section.

Step 2: When Ac1dSn0w has downloaded you will need to launch the Jailbreaking application by double clicking it.

After Ac1dSn0w is running you will notice a fairly straightforward interface presented to you with 6 available options:

Simple DFU mode is a status devised and sanctioned by Apple and is easily attained using a combination of buttons on your iPhone. Pwned DFU mode is different in that you have arrived in the DFU mode status by using the Limera1n exploit and not by using the authorised button approach above. Effectively you have taken control of the DFU state.

• Jailbreak: Pressing this button will begin the Jailbreaking process.
• Tethered Boot: Pressing this button will simply allow you to re-boot your tethered iPhone into a usable Jailbroken state.
• Pwned DFU: Pressing this button will force your iPhone into Pwned DFU mode. In this mode your iOS Device is able to be exploited by various Jailbreaking programs.
• Exit Recovery: Pressing this button will reboot your iPhone that is trapped in an endless Recovery Mode cycle.
• Show Console: Clicking this option will bring up a new window that shows information about your iPhone, as well as Jailbreak status information.
• Show Assistant: Clicking this option will bring up DFU mode instructions.

Step 3: The first thing you will need to do to prepare for Jailbreaking your iPhone is plugging it into your computer. Do this now, and ensure iTunes is closed and your iPhone is powered off.

Note: To ensure your iPhone is being recognized by Ac1dSn0w you can click the Show Console option.

Step 4: After your iPhone is plugged into your computer and it is powered off, click the Show Assistant Button and follow the instructions to put your iPhone into DFU mode.

Step 5: When your iPhone is in DFU mode you need to press the Jailbreak Button and Ac1dSn0w will begin Jailbreaking your iPhone.

Step 6: Once Ac1dSn0w is finished Jailbreaking your iPhone you will need to boot tethered. To do this put your iPhone back into DFU mode by pressing this show assistant option, and then once in DFU mode press the Tethered Boot button.

Optional: SemiTethered Jailbreak – Though you have now Jailbroken your iPhone tethered on iOS 5 or iOS 5.0.1, you can actually SemiTether your iPhone. SemiTethering your iPhone basically means that you will be able to still use it if it ever loses power (with limited functionality). In order to SemiTether your iPhone you will need to add the following repository through Cydia:

Then search for the SemiTether Cydia package, install and reboot your iPhone (yes, you will need to boot tethered again). If you are looking for a more detailed guide.
