Preserve iOS 6 baseband - Create iOS 6 Custom IPSW Firmware

Click on the Extras and then on Custom IPSW option, select the required iOS 6 IPSW and let RedSn0w make the custom firmware.

The new re-store features allow third gen iPad and iPhone 4S users to re-store to any version of iOS 5.x although Apple is not signing the software. You will just need the SHSH blobs for your iOS 5.x. The downgrade can only be done if you updated your device using iTunes and will not work if the upgrade has been done OTA (Over The Air). iPad 2 users will be able to downgrade if they have blobs from 4.x and 5.x saved. The A4 based iPhone 4, 3GS and 4th-gen iPod touch users can downgrade to an older firmware for untethered jailbreak provided that they have SHSH blobs saved for the firmware they want to downgrade to.

There are still no iOS 6 untethered jailbreak although the Dev teams are working hard on the issue. Stayed tuned for more unlock & jailbreak updates and feel free to comment. As soon as any new update concerning jailbreaks come out, we will let you know ASAP.

What if your phone factory unlock do you still have to preserve your baseband?


I tried to jailbraik on Iphone 4 but during the process it freezes and redsnow shows erorr and stops. It seems the iOS 6 is harder to crack. Also, during the process of jailbraiking the process loads lot of memory!! Did anyone tried it yet?


No, Factory Unlocked iPhones can be updated without preserving your baseband.

Question: I’ve recently pursched a new iPhone 4S from ebay, sadly to my dismay the phone is password protected & has a clean “esn” according to Verizon. The iPhone 4S is password protected, and the password is unkown rendering it useless to me (I’ve tried DFU on my itunes account yet the owner “Eddie’s A Ipod” cannot be rebooted), is there any jailbreaking software or other party software that will allow me to restart the phone? The phone itself has IOS 6.0 : (


Update: you can jailbreak iOS 6.1 using Evasi0n Jailbreak on iPhone 5, 4S, 4 and all other Apple devices. Our full iOS 6.1 jailbreaking guide can be found here.

Dhave Barsalote

help guys, 'cuz whenever i updated my iphone 4 ios 6.0 to ios 6.1 as it says in my software updates it always says in the nearest end that Update Is Failed. My Iphone is already a Jailbroken. I wan't to update it because my current ios version right now is not compatible with the carrier network that i've been using. And i've heard that 6.1 fixes those Bugs.
