Step 2: Update/Restore to iOS 4.2.1 using the IPSW file you just downloaded via iTunes 10.1.
Step 3: Start Redsn0w 0.9.6b4 and point it to iOS 4.2.1 firmware to proceed with the jailbreak.
redsn0w-0.9.6b4-6.pngredsn0w-0.9.6b4.png
Step 4: Now select "Install Cydia" and click "Next". Optionally (if available), you can also select any other option you like.
redsn0w-0.9.6b4-1.pngredsn0w-0.9.6b4-2.pngStep 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click "Next".

Please post the solution. Why is there no "software update" on my IPad 2?


There are two ways to upgrade the iOS version of your iPad

- or directly from within the device, but only since iOS 5, it is possible to upgrade the iOS version without the need to connect the iOS device to a computer (over-the-air update)
just go to: settings - general - software update
- so in your case try an update with a computer with iTunes installed:
- procedure with iTunes connected:
  • Connect your iOS device to your computer using an USB cable. Wait for iTunes to open and connect to your device.
  • Click on device button to the left of the iTunes Store button in the top right corner in iTunes.

How to unlock iPhone using PwnageTool or redsn0w + ultrasn0w combination


This will guide you on activating, jailbreaking and unlocking your iDevice & thus will be of 2 parts: Part 1 - Jailbreak with redsn0w; & Part 2 Unlocking with ultrasn0w.

Hardware compatibility:
  1. UNTETHERED JAILBREAK - iOS 4.2.1, 4.1, 4.0.2, 4.0.1 and 4.0
    • iPhone 3G
    • iPhone 3GS old bootrom
    • iPod touch 2G non-MC model kid_ant_5.png
  2. TETHERED JAILBREAK (?) - iOS 4.2.1 ONLY - you can use either greenpois0n or sn0wbreeze for untethered jailbreak, for these iDevices:
    • iPhone 3GS new bootrom
    • iPhone 4
    • iPod touch 2G MC model
    • iPod touch 3G
    • iPod touch 4G
    • iPad kid_ant_5.png
  3. UNLOCK - iOS 3.0 up to 4.2.1
    • iPhone 3G
    • iPhone 3GS old bootromkid_ant_5.png
  4. UNLOCK - iOS 3.0 up to 4.0.2 ONLY
    • iPhone 3GS new bootrom
    • iPhone 4
Not sure if your iPhone 3GS has old or new bootrom? CLICK HERE. Or if your iPod touch is MC or non-MC? CLICK HERE.

Compatible basebands (BB) for ultrasn0w 1.2.2:
  • 06.15.00 - iOS 3.2.2 from iPad (read further for details)
  • 05.13.04 / 01.59.00 - iOS 4.0.2, 4.0.1 & 4.0
  • 05.12.01 - iOS 3.1.3
  • 05.11.07 - iOS 3.1 & 3.1.2
  • 04.26.08 - iOS 3.0
Notice that BB 05.14.02 & 05.15.04 are NOT part of the list. You need to update these BB to 06.15.00 for ultrasn0w unlock to work. Read further for more info.

However, if your BB is 05.13.04 or lower, you can proceed with jailbreaking but make sure you DO NOT INSTALL THE IPAD BASEBAND.

WARNING: Read the following consequences of updating BB to 06.15.00:
  1. There is no way to come back down from 06.15, & there's no hiding the baseband version from Apple. You'll be voiding your warranty in a very obvious way. kid_ant_5.png
  2. If some future baseband comes out with a critical fix, you won't be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn't update to it if you wanted to keep your unlock anyway). kid_ant_5.png
  3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won't ever be able to restore to stock firmware (it will fail). You'll need to only restore to custom IPSWs (then again, if you're unlocker you should already be doing that).
DO NOT PROCEED if you don't agree.

What you need: NOTE: Download iPad's 3.2.2 IPSW ONLY if you'll use PwnageTool. Also, download ONLY the IPSW for your current iOS version. CLICK HERE if you have no idea what version is installed on your iDevice, especially if it's currently disabled.

For jailbreaking other iOS versions like 4.3.2, use other versions of redsn0w. CLICK HERE to see the list of all redsn0w versions.

Procedures:

PART 1 - JAILBREAKING with redsn0w (all iDevices):
  1. Connect your iDevice to the computer, run redsn0w & click Browse kid_ant_5.pngkid_ant_57.jpgkid_ant_5.png

  3. Wait until it say IPSW successfully identified. Click Next kid_ant_5.png
  4.

This will result to updating your BB to 06.15.00 which can be unlocked using ultrasn0w. kid_ant_5.pngAlso, if your BB is 05.13.04 or lower, this jailbreak will still work for your iPhone but make sure you DO NOT INSTALL THE IPAD BB! You don't need it! kid_ant_5.pngFor iPod touch users, the BB thing does not apply for you. so you have nothing to worry about.kid_ant_5.png

How to jailbreak using sn0wbreeze (snowbreeze) on all iDevices


This will guide you on updating, hactivating, jailbreaking and keeping your baseband ready for unlock by using sn0wbreeze 2.1

This jailbreak is great for iPhone users who's been waiting to update to iOS 4.1 but wants to keep their unlock to keep the phone functionality.

Because this jailbreak process involves updating your iDevice's iOS version, I recommend saving your iDevice's SHSH blobs NOW! CLICK HERE to learn how.


iDevices that are not listed above are not compatible with new iOS updates (from iOS 4.0 to the latest 4.1). DO NOT USE this jailbreak if you don't see your iDevice above!

Sn0wbreeze is currently for Windows only. Possibility of having a Mac version is uncertain.

These are the files that you need:
  1. sn0wbreeze 2.1
  2. Official 4.1 IPSW for your iDevice (select/click on your iDevice to download IPSW). If an Ad appears, just click SKIP THIS AD on the top left corner to continue on downloading:
The above list also represents all supported iDevices by sn0wbreeze.

Procedure:
  1. Run sn0wbreeze, click OK, click Close Credits and click Nextkid_ant_10.jpgkid_ant_24.jpgkid_ant_10.jpgkid_ant_25.jpgkid_ant_10.jpgkid_ant_26.jpgkid_ant_10.jpg

  4. sn0wbreeze identifies your iDevice base from the iPSW you selected. Once it's done, click Next kid_ant_10.jpgkid_ant_30.jpgkid_ant_10.jpgkid_ant_31.jpgkid_ant_10.jpg
  5. Select Expert Mode then click Next kid_ant_10.jpgkid_ant_32.jpgkid_ant_10.jpg
  6. Select General then click Next kid_ant_10.jpgkid_ant_33.jpgkid_ant_10.jpg
  7. Choose your preferences then click Next kid_ant_10.jpgkid_ant_34.jpgkid_ant_10.jpgBasically, the 3 options on the left are for iPhone 3G and iPod touch 2G users only because these features are already available (as a default) on newer iDevices such as the iPhone 4. kid_ant_10.jpgActivating is for iPhone users only. kid_ant_10.jpgLastly, SSH is something that let's you access the files and folders on your iDevice. You don't wanna mess with this if it's new to you.kid_ant_10.jpg
  8. Click Next again kid_ant_10.jpgkid_ant_35.jpgkid_ant_10.jpg
  9. Click Build IPSW then click Next kid_ant_10.jpgkid_ant_36.jpgkid_ant_10.jpg

The filename should contain the word "sn0wbreeze_" on it so there's no chance that you get it confused with the official IPSW from Apple. kid_ant_10.jpgWatch this video...kid_ant_10.jpgkid_ant_10.jpg
  11. Plug in/connect your iDevice to your PC (computer) kid_ant_10.jpg
  12. Turn your iDevice OFF and prepare to put it to DFU mode kid_ant_10.jpgkid_ant_40.jpgkid_ant_10.jpgYou can also opt to close sn0wbreeze and use iReb instead. Download iReb HERE.kid_ant_10.jpg
  13. Click on Start. kid_ant_10.jpg
  14. Press and hold POWER and HOME buttons for 10 seconds kid_ant_10.jpgkid_ant_41.jpgkid_ant_10.jpg

I mistakenly restored my iphone 3gs's ios to 6.1.3 but it does not work now how can i downgrade my iphone's ios to appropriate ios?


Just google the stand alone IPSW file. they highest you would be able to go is 4.2.1 Find the file, download it to your computer, then go into iTunes and right click on check for downloads on the summary page and it will let you specify which .ipsw file you want to use to downgrade the SW. If the device was jailbroken there is a chance the device may be bricked for good now just so you know. Good luck.

Downgrade iPhone 4, 3GS from iOS 4.0.2 to 4.0.1 Without SHSH Blobs Saved [Update...


Download iOS 4.0.1 ipsw from here.
Extract it with WinRAR or WinZip to a folder on the desktop. You may need to rename the firmware file from .ipsw to .zip to do this.
Open the buildmanifest.plist with the Notepad if you are on Windows, or TextWrangler if you are on Mac.
Search and replace all – 8A306 with 8A400. Save. Repeat the same with the file restore.plist.
Download iOS 4.0.2 ipsw from here and open this with WinRAR or WinZip.
Note: Do not extract it. Just open it and leave it open. You must use this exact file and not create a new one. If you have to create a new one for reasons like you are on OS X, then use zip command line not explorer or finder to make the zip. I will assume you are using the original file opened in WinRAR for the rest of this guide.
Take all the files from iOS 4.0.1 and drag them over to the iOS 4.0.2 zip archive that you have open.
Delete all the .dmg files that have 002 at the end, leaving only the 001 files left.
Save the archive, and rename it back to .ipsw if you changed the name to get WinRAR/WinZip to open it.
Put the device in DFU
Now simply open iTunes and restore the firmware you changed.
This is it, you should now be able to jailbreak and unlock your device on iOS 4.0.1 with JailbreakMe
