3GS, 4.0, 4.0.x, downgrade, iPhone 3G S, iPhone 4, SHSH, TinyUmbrella »

[8 Sep 2010 | 4 Comments | ]

Apple just released iOS 4.1 update, not a super important update for 3GS users (unless you are into GameCenter!). iPhone 4 users can finally relax given that iOS 4.1 comes packaged with a fix for those nasty sensor issues.

Before you do any thing, please quit iTunes and do the following. TinyUmbrella is what you need to save your iPhone from Apple’s anti-jailbreak updates.
Download TinyUmbrella for your Mac/Windows/Linux.
Install/Launch TinyUmbrella and save SHSH blobs for iOS 4.0.2 for 3GS, iPhone 4 from Apple (or Cydia after the SHSH blob signing period by …

Apple released iTunes 8.2 just in time for a probable iPhone 3.0 release at WWDC ’09. While iTunes 8.2 adds support for iPhone 3.0 goodness, it strips iPhone off of all the Jailbreak excitement! If you upgrade to the latest version of iTunes, you will no longer be able to Jailbreak the iPhone nor use SSH over USB. Apple changed some protocols in MobileDevice framework which resulted in panic-mode amongst the jailbreak community! The added security implemented some serious checks on the device hardware/software (security epoch, chipid, security domain, production …

So, you are the curious type and upgraded to 2.0 though you had no intentions of signing an official contract? That has some serious outcomes wherein you have 3 options after the upgrade to 2.0 :
1) Sign a contract with the updated iPhone 2.0, you don’t want to do that do you?!
2) Jump ahead to Sleepers.net, the best one out there! Pay close attention to DFU mode! Error 20 can be frustrating at times!
3) Wait for iPhone Devs to release an offcial tool (pwnage) real soon!
This post is an attempt …

iPhone 1.1.4 upgrade hasn’t been a trouble-free update for many. There really is no good reason to update to 1.1.4 at this time, probably SDK might need it in the future. So, you accidentally upgraded to 1.1.4, now what? How do we get back to a much better firmware?
Download 1.1.3 / 1.1.2 firmwares from this link.
I have followed these steps on a 4.6 BL iPhone as well as 3.6 BL iPhone. If you have used IPSF like unlock before (Gunlokc/iJailbreak/ZiPhone), then you can still follow these steps.

1.1.3, downgrade, jailbreak »

[3 Feb 2008 | 7 Comments | ]

I upgraded an OTB 1.1.2 to 1.1.3 using Nate’s method. I found it to be a pretty not-so-complicated upgrade. Then I tried SummerBoard which made me think twice about using DevTeam’s jailbreak instead. SummerBoard posed so many issues with Nate’s 1.1.3 Jailbreak. So, following are the steps taken to downgrade a 1.1.3 Jailbroken (Nate) iPhone to 1.1.1 followed by an upgrade to 1.1.2 and then finally upgrading to 1.1.3 using DevTeam’s Jailbreak.
Files needed : 1.1.1, 1.1.2 firmware files.
Step 1 : Sync your iPhone to iTunes. Hold the home and …
