Download PwnageTool 4.2 – Untethered Jailbreak iOS 4.2.1 + Preserve iPhone Baseband

iPhone dev-Team has just released PwnageTool 4.2, the untethered jailbreak for iOS 4.2.1. You can download PwnageTool 4.2 jailbreak from the link below. PwnageTool 4.2 creates custom IPSW to jailbreak iPhone, iPad, iPod Touch and AppleTV 2G and also preserves iPhone baseband so that you may unlock with UltraSn0w.

Supported Devices:

  • iPhone3G

  • iPhone4
  • iPhone4-Verizon
  • iPod touch 3G
  • iPod touch 4G
  • iPad
  • AppleTV 2G

Note Supported: iPod Touch 2G

What’s in a name? Well in the case of an HFS volume name on iOS, an untether exploit — as the Chronic Dev Team revealed last week with an untether for the 4.2.1 jailbreak, which had previously been a tethered JB for most recent devices since 4.2.1’s release in November. With their permission, we’ve incorporated their 4.2.1 “feedface” untether into today’s PwnageTool 4.2. This means iPhone unlockers can safely restore to a custom iOS 4.2.1 pre-jailbroken IPSW and retain their current baseband and unlock. PwnageTool also supports all the other 4.2.1 devices other than iPod touch 2G:

* iPhone3G
* iPhone3GS
* iPhone4
* iPhone4-Verizon
* iPod touch 3G
* iPod touch 4G
* iPad
* AppleTV 2G

PwnageTool also includes two very recent improvements to the 4.2.1 JB: iBooks was just fixed by @comex and @pushfix last night so that it works as intended on DRMed books, and the wifi problem on AppleTV 2G was fixed by @nitotv, @DHowett, and @saurik. Both of these fixes will also be available in upcoming Cydia package updates, so if you’re already jailbroken you can wait for those updates rather than restore and jailbreak again.

The various components to the 4.2.1 untether (including a second exploit involving Mach-o headers) were worked out by 0naj, posixninja, and pod2g, and a nice writeup by 0naj is available on the wiki. The actual injection method uses geohot’s limerain exploit for most devices. And even though 4.3 is just around the corner, the exploit used has already been closed in the latest 4.3 betas, so it made sense for the 4.2.1 untether to be released when it was. It also appears that a security researcher named @i0n1c has a 4.3 untether ready for when Apple releases the final 4.3 FW, so it may not be a long wait at all with 4.3!

Did you update your firmware by preserve baseband ? If not then you wont be able to unlock your iphone because you baseband already update to 3.10.00. Only thing you can do now is wait, wait, and wait.

I just used Pwnage 4.2 to update my iPhone 3GS 4.1 BB 6.15.00 to 4.2.1 and everything worked like a charm.

I was a little nervous as I had BB 6.15.00 (the custom firmware one) but good thing is my BB was preserved + I got upgraded to 4.2.1

Everything worked out really smooth & without any hitches. Just like the previous Pwange tool.

Personally I think Pwange is the BEST way to upgrade and jailbreaks iphones. I tried redsnow in the past & it was very buggy and cumbersome in compare.

Thanks to everyone involved in creating the lives of iPhone unlockers so much easier. You Guyz Rock

I have used the Pwnage tool to jailbreak and activate the iphone 4 but when I try to restore the custom ipw in iTiunes 10.2.1 it says is not eligible for restoration. Any ideas why it is so, and why I can fix it?

ipad 3 vs ipad 2 July 15, 2012, 9:33 pm

My iPad 3 had very poor wifi reception too. It must be considered a software issue
with the iPad. The only thing I can think of doing is getting a modern router and try that.
