jailbreak iphone 4 4.2 ios – Redsn0w Jailbreak
Few moment ago we broke the news about the release of redsn0w 0.9.6b4 to jailbreak iOS 4.2.1 on iPhone 4, 3GS, 3G, iPod touch 4G, 3G and iPad with working Cydia and MobileSubstrate, as we told you earlier that redsn0w 0.9.6b4 is based on GeoHot’s limera1n bootrom exploit.
The bad new is that right now, the redsn0w 0.9.6b4 is a tethered or semi-tethered jailbreak for some devices (i.e. you will lose your jailbreak every time you reboot your iDevice, so you have to follow the following steps every reboot to have a jailbroken device )
Untethered Devices:
- iPhone 3GS (old bootrom)
- iPhone 3
- iPod touch 2G (Non-MC Model)
Tethered Devices:
- iPhone 3GS (new bootrom)
- iPhone 4
- iPad
- iPod touch 2G (MC Model)
- iPod touch 3G
- iPod touch 4G
NOTE: Those of you who rely on a carrier unlock stay away from Redsn0w and iOS 4.2.1.
GUIDE:
STEP 1: Download redsn0w 0.9.6b4, iOS 4.2.1 for your device(download links at the end).
STEP 2: Update to 4.2.1 firmware using the IPSW file you just downloaded via iTunes 10.1.
STEP 3: Launch Redsn0w 0.9.6b4, and browse for iOS 4.2.1 firmware final version
STEP 4: Select “Install Cydia” and click on “Next“
STEP 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.
STEP 6: At this stage you will need to put your iPhone in DFU mode by holding “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.
STEP 7: You will Get a Jailbroken Device on the latest iOS 4.2.1 as soon as the process ends.
STEP 8: This step is only for these devices iPhone 4, 3GS (New Bootrom), iPod touch 4G, 3G, 2G, iPad. While this is tethered jailbreak and whenever you want to do anything related to jailbreak like SSH your device, or running Cydia, you must first run your device in the so called “jailbroken state” on every reboot by using “Just boot tethered right now” option.

this is great works for me on ipad cheers guys
Am trying to Jailbreak 4.2.1, and after DFU mode, phone shows an icon “Downloading Jailbreak Data..” and Redsn0w program screen says “Uploading ramdisk” Does this procedure take 15-20 minutes, or is the system hanging. (I ran Redsn0w as an administrator).
After about 10 minutes of waiting, the green charging battery appeared, since the phone was hooked up to the laptop. I then powered down the phone, rebooted, but I don’t see the Cydia icon anywhere on the phone’s desktop, so how do I know if the jailbreak worked? (where will the Cydia icon appear?)
The software developers of RedSn0w should modify the code to respond better during this period, since only web pages mention a time delay.
Ehm. Doesnt work for 2g mc ipod touch!!
Ehm. Doesnt work for 2g mc ipod touch!!
u guys really need to update your guides…
For the “white apple icon” problem or problems occurring after you first see the Cydia icon, any time your Iphone asks you to reboot you need to simply power it down. Then, hook it up to your pc again and go through the redsnow commands, and then select “just reboot tethered right now” and let it reboot and you will be fine. The key is that any time Cydia or Wifi says “reboot” you need to go back to your pc and do a “tethered” reboot. Future software will provide untethered reboots, but not at present.
