How to do an untethered 4.3.3/4.2.8 jailbreak with Redsn0w 0.9.6rc19 [Tutorial]
This is a tutorial on how to use the new version of Redsn0w 0.9.6rc18 to run an untethered jailbreak on all iDevices running 4.3.3/4.2.8 firmware EXCEPT for the iPad2. This tutorial is for both Mac and PC.
Step 1: Restore or update(we recommend clean restore) your firmware to 4.3.3(GSM) or 4.2.8(CDMA) you can use the firmware file you downloaded by clicking shift+restore instead of downloading it from the Apple server.
Step 2: Start Redsn0w 0.9.6rc19 and point it to the 4.3.3/4.2.8 firmware you downloaded
Step 3: After you've selected the firmware and Redsn0w says "firmware verified" click next and you will see a progress bar as Redsn0w prepares the firmware with the jailbreak data. If successful you will be brought to the options screen where you should select "Install Cydia" and "Allow boot animation" if you want to enable custom bootlogos.
Step 4: After you've checked the boxes "Install Cydia" and "Allow boot animation" click next which will bring you to a screen that will prepare you to enter DFU mode. Please power off your device and connect it(if not already) at this time.
Step 5: At this time, Redsn0w will walk you through the DFU mode process if you don't know how to do it already. If you are having issues with timing, you might want to check out our DFU mode video tutorial which will help you get the timing down.
Step 6: Congratulations you've made it to the end! As soon as Redsn0w detects your device in DFU mode you can just sit back and relax while it does it's thing! As soon as it is complete, you will be jailbroken and untethered on 4.3.3/4.2.8! If you have any feedback or questions please feel free to post below. Thanks!
How to fix the stuck at uploading ramdisk issue
Some of our users have reported an issue with Redsn0w that it will get stuck during the "uploading ramdisk" portion of the process. The fix for this is very simple. Go to where Redsn0w is stored and right-click it and select "properties" under the compatibility tab change the compatibility mode to "Windows XP Service Pack 2" and check the box that says "run as administrator." After you have done those 2 things hit apply and then re-open Redsn0w and try the jailbreak process again. It should go through without a hitch!
