If you’re a developer, and you have an iPhone 4, 3GS, or iPod touch 4th generation running iOS 6 beta, then step inside as we showcase how to jailbreak with this development version of RedSn0w.

Note: This is aimed at developers only. Again, this will not install Cydia on your device, will not hacktivate, and it’s suggested that unlockers who want to preserve the baseband, stay away. This only works with iPhone 4, 3GS, and iPod touch 4th gen. No A5 Devices. This is a tethered jailbreak.

Step 1: Download and open RedSn0w 0.9.13dev1.

Step 2: Click Extras > Select IPSW, and point to your iOS 6 firmware file for your device.
Step 3: Click back and Click jailbreak. Place your device into DFU mode, and the jailbreak should begin. RedSn0w will prompt you to Install SSH. Make sure that option is checked, and click Next. the jailbreak will proceed until completion.
Step 4: Once on your Home screen, go back to RedSn0w and click Extras > Just boot. This will perform a tethered boot. You will need to place your device into DFU mode again to proceed.
Step 5: Once the tethered boot is completed, your device will go back to your Home screen. Congratulations, your device is now jailbroken. You can now use SSH, or another iPhone file navigation utility to browse the default file structure. This may allow you to install apps and tweaks manually if need be. Again, this is for advanced users only, as no GUI interface is there to help you through this process.

What that means, you will be able to cook your custom firmware from Redsn0w directly which was the major advantage of PwnageTool and Sn0wbreeze. Both PwnageTool (for Mac) and Sn0wbreeze (for Windows) are being used mainly by who rely on unlock for their iPhones as they can preserve the unlockable baseband so they can unlock their iPhones with ultrasn0w. Now Redsn0w new feature will kill the both PwnageTool and Sn0wbreeze for ever, as Redsn0w is always available for both Mac and Windows. The only case that the Dev-team will upgrade PwnageTool is only in case of untethered jailbreaks.

Thanks Dev-team about your continuous hard work and improvements. This is really awesome.

iOS 5 (Official) can be jailbroken (tethered)

• This will not work with iPad 2, nor the iPhone 4S.
• This is a tethered jailbreak, meaning that it will require you to connect the phone to a computer running Redsn0w whenever you power up the phone.
• As has been the case before, by pursuing the tethered route, if and when an untethered jailbreak does surface, the chances are you’ll have to restore in order to utilize it.

The iPhone Dev-Team has released RedSn0w 0.9.8b4 for developers to jailbreak iOS 5 Beta 4. Remember this is a tethered jailbreak.

In conjunction with iOS5 beta4 being released to iOS developers, redsn0w 0.9.8b4 is now available for jailbreak app developers. Remember, its a tethered jailbreak right now so youll need to use redsn0w to boot into a jailbroken state at each power cycle.




NOTE: It appears that by design, the OTA update that became available starting with iOS 5 beta4 will *not* be automatically applied to jailbroken devices. Thats a relief to those who dont want to lose their jailbreak via OTA pushes. If youre jailbroken, youll need to use the standard iTunes method to get to iOS 5 beta4.

You can download the new version of RedSn0w from here: Windows, Mac.

If you hit a 1604, 1603, 1602, 1601, 1600 error while trying to restore your iPhone with a custom iOS 5.0.1 firmware file created using Redsn0w then there is now a way to bypass the error.iH8sn0w, developer of Sn0wbreeze has released a new version of iREB tool after almost 10 months, which is compatible with iOS 5.0.1.


iREB is a tool that will put your iOS device into a pwned state so that you can upload custom firmware to it.In addition to the iOS 5.0.1 support, iREB r5 includes a number of fixes and improvements:

• Much smaller file size (390kb).
• Fixed USB 3.0 issues.
• iREBs speed for the iPhone 2G/iPhone 3G/iPod Touch 1G has
• increased significantly!
• Fixed rare DFU detection issues.
• Updated limera1n/steaks4uce payload to not hook "cmd_go"
• on 4.x images (nothing severe, but useless here).

iREB is currently available for only Windows. You can download iREB r5 using this link.
We havent tried it out yet, but if youre looking for a step-by-step guide, you can checkout below to get an idea on how to use it.
====How To Fix 1604, 1603, 1602, 1601, 1600 Error While Restoring Custom iOS 4.2.1 IPSW Firmware File Using iREBIf you hit a 1604, 1603, 1602, 1601, 1600 error while trying to restore your iPhone with a custom iOS 4.2.1 firmware file created using Sn0wbreeze 2.2 for Windows or PwnageTool 4.2 for Mac then there is a way to bypass the error.iH8sn0w, developer of Sn0wbreeze has released a new version of iREB tool, which is compatible with iOS 4.2.1.

iREB is a tool that will put your device into a pwned state so that you can upload custom firmware to it.iREB RC3 supports the following iOS devices:

• iPhone 2G, iPhone 3G, iPhone 3G[S] (old & new bootrom), iPhone 4
• iPod Touch 2G (MB & MC), iPod Touch 3G, iPod Touch 4G
• iPad
• Apple TV 2

iREB is currently available only for Windows users.Before we start please note that that jailbreaking your iOS device may void its warranty and hence proceed with caution and at your own risk.You can follow these simple step-by-step guide to bypass the 1604, 1603, 1602, 1601, 1600 errors:

• Download the latest version of iREB from iH8sn0w
• Start iTunes (iREB needs iTunes 10 or above, it’s a good idea to use the latest version of iTunes – iTunes 10.1.2 as of now)
• Put your iOS device in DFU mode by following these steps:
  • iPhone/iPad/iPod Touch
    • Connect your iPhone/iPad/iPod Touch to your computer
    • Turn it off
    • Hold power and home together for 10 seconds (exactly).
    • Release power but keep holding home until the computers beeps as a USB device is recognized
    • A few seconds later iTunes should detect your iOS device
  • Apple TV 2
    • Connect your Apple TV 2 with your Computer via microUSB
    • Now reboot your Apple TV by holding down Menu + Down buttons together for around 6 seconds
    • After reboot, immediately hold Menu + Play until you see the message in iTunes saying that Apple TV in recovery mode is detected
• Now close iTunes and launch the iREB tool that you had downloaded earlier
• Click on the relevant device from the iREB screen and wait for few seconds until you get a white or red screen on your iOS device
  
• Now start iTunes again and select your iOS device from the left hand side side bar
• While on the iTunes window, hold the Shift key and click on the Restore button. (This is a VERY IMPORTANT STEP as just clicking the ‘Restore’ button without the ‘Shift’ button will result in restoring your iPhone with the latest firmware, by holding down the ‘Shift’ button, allows you choose the custom iOS 4.2.1 firmware file created using PwnageTool or Sn0wbreeze)
• Navigate and select the custom iOS 4.2.1 IPSW file to restore your iOS device with it

You should now be able to successfully restore your iOS device with the pre-jailbroken iOS 4.2.1 firmware file without hitting the 1604, 1603, 1602, 1601, 1600 error.

The iPhone Dev Team quietly released RedSn0w 0.9.13dev2 to address issues with SSH and app crashes that some users were experiencing.

The developer versions of RedSn0w are for developers wishing to jailbreak their iOS 6 beta installations. Since this version of RedSn0w does not install Cydia, SSH access is imperative, hence the fix for the users experiencing difficulties.
Per the Dev Team’s Blog:

Update #1: The “dev2” version should fix the various SSH problems and crashes with apps that some have been seeing.

Head over to our downloads page to download this latest version of RedSn0w. To learn how to jailbreak your iOS 6 beta installation, check out our iOS 6 beta 2 jailbreak tutorial.

Please note, that RedSn0w 0.9.13dev2 was not released with the intent to allow you to use the latest iOS 6 beta 2 release from Apple. For this reason, you will still need to point back to previous firmware as outlined in our iOS 6 beta 2 jailbreak tutorial.

The iPhone Dev-Team has announced RedSn0w 0.9.15b1 which brings numerous new features including the ability to restore to older firmware not being signed by Apple.


New Features:

● restore from any 5.x iOS to any other (up, down or the same) 5.x iOS on all devices as long as you have the correct blobs (see more below)
● Cydia now included in the tethered 6.0 jailbreak on A4 devices
● automatically "Just Boot" tethered when qualifying A4 device connects in DFU mode
untethered 6.0 jailbreak on old-bootrom 3GS
● untethered 6.0 hactivation on any 3GS or iPhone4
● directly restore pre-A5 devices to earlier firmware - no more complicated 15-step how-tos with stitching, iTunes errors, and "hosts file" concerns
● fetch new signed blobs for any IPSW (present or future - no redsn0w update required) using Extras->SHSH Blobs->New
● block the BB update for any 3GS or iPhone4 restore (past, present, or future - no redsn0w update required) using Extras->Even More->Restore
● deactivate any iPhone, useful for testing your "official" unlock status through iTunes. (Please only deactivate your own iPhone!)
● activation status shown on "Even more" page
● significantly more (very nerdy) info returned by "Identify" button when device is in Normal mode
● tethered jailbreak of ATV2 supported (but the only thing available for it is the SSH2 custom bundle available here - no Cydia yet. Must use "Select IPSW" for tethered boot of ATV2 for now).
● auto-exit WTF mode for older devices with broken buttons
● any time a set of blobs is fetched remotely (from Apple or Cydia), redsn0w also saves them locally (and will check there first if you click "Local")
● for your future restoring convenience, you should also submit all of your past and present TinyUmbrella blobs to Cydia if you havent done so yet. Resubmitting is okay and wont cause conflicts.


iOS 5 to iOS 5 Restores for A5+ Devices

1. redsn0w now lets you restore an A5+ device from any iOS5 to any other iOS5 as long as you have correct 5.x blobs for the starting (current) and ending points of the restore

• APtickets eliminated "higher-version only" comparison of firmware restores (just like BBtickets did for the baseband)
• example restores supported by redsn0w if you have the correct blobs: 5.1.1-to-5.0.1, 5.0.1-to-5.1.1, 5.1.1-to-5.1.1, 5.0.1-to-5.0.1
• if you dont have the blobs locally, let redsn0w try to fetch them remotely (redsn0w always tries both Apple and Cydia). Any succesful remote fetch also saves a local copy too.

2. You DO NOT QUALIFY for iOS5-to-iOS5 restores if you got to your current 5.x via an OTA update

• the tickets saved by Cydia, redsn0w, and TinyUmbrella do not cover OTA update ramdisk images
• even if they did, its the "wrong kind" of ramdisk (youd need to start at that earlier pre-OTA FW)
• devices fresh from factory or refurb may fall in the "does not qualify" category (your results will vary)
• its okay if you previously got to 5.x via an OTA update, as long as your current 5.x was installed via a normal iTunes restore. All that matters is how you got to your current 5.x most recently
• redsn0w detects an OTA/normal-restore APticket mismatch very early, so if you dont know your status there should be no harm in trying. Any device in recovery mode after such a mismatch can boot normally again just by going back to "Even More" screen from the "Restore" screen (or use "Recovery Fix" if you quit redsn0w before doing that).

3. Unlike the A4 devices, redsn0w cant (usefully) prevent the baseband updates of A5+ iPhones and iPads.

• and so, redsn0w automatically flashes the currently signed baseband when it does A5+ restores, even if those basebands didnt come with the original firmware
• stay away from this if you have an unofficial unlock that isnt supported by the newest baseband
• ● the least-tested baseband update code in redsn0w is for iPad2,3 and iPad3,2. Please give any feedback on those iOS5 restores in the comments section below.

4. iPad2 owners (all three models) with saved 4.x blobs can use those instead, even from 6.x

• if you have both 4.x and 5.x iPad2 blobs, you can always get to 5.x via the 4.x blobs, even if youre currently on 6.x
• you cannot get to 5.x from 6.x without the 4.x blobs (but you may still qualify for the iOS5-to-iOS5 restore described above)
• if somehow you have 4.x blobs but no 5.x blobs, you can still go down to 4.x from 6.x
• this only applies to iPad2 owners (theyre the only A5+ devices that ever had a public 4.x FW)
• redsn0w still supports (but doesnt require) jailbreaking A5+ devices at 5.0.1 and 5.1.1. Just head back to the first page after re-restoring to 5.x. Its always much faster to jailbreak those FW versions with a freshly-restored device, before letting iTunes restore from a saved userland backup.

5. ultrasn0w isnt yet updated for 6.x

• by now you probably should be taking advantage of the extremely cheap IMEI-based unlocks of iPhones sold by established online retailers like http:://cutyoursim.com
• still, IMEI-based unlocks dont work in all cases. Well announce when ultrasn0w is ported up to 6.x
• redsn0w will still hactivate your 3GS or iPhone4 if you run it before the device is activated. Due to the current tethered 6.x JB status, redsn0w now hactivates 6.x without requiring subsequent tethered boots. If you accidentally hactivate with redsn0w, use the "Deactivate" checkbox available from the Jailbreak screen, not the normal one in "Even more"

6. As always, redsn0w lets you "Fetch" the SHSH blobs currently flashed onto your pre-A5 device

• use this if youre at 5.x or 4.x but without having saved your blobs when the window was open
• this is only useful when Apple is no longer signing the firmware, otherwise Cydia/redsn0w "New"/TinyUmbrella blobs are superior (but youre welcome to fetch your 6.0 blobs this way anyway)
• fetching blobs in this fashion will automatically forward them up to Cydia, as well as save a local copy

Occasionally issues like system registry instability, corruption of system files and slowing of system performance can lead to such problems. Hardware failure can be an acute cause as well.

In order to avoid this error and get the functionality back, it is advised that users run an anti-virus scan to eliminate the possibility of a virus; and hence the issue of corrupted files can be catered to. The QuickTime app should also be checked for corrupted files as well, since a simple reinstall would do the job for you.

A recommended procedure for such is to undo the compatibility mode for QuickTime. This should be done when Windows is being used as an operating system. The steps are as follows:

How to Fix iTunes Error 3191 iPhone 4 on iOS 5 / 5.0.1 :

1.In order to do this, go to “Program Files” in your Local Disk (C). A simple search would lead you to the QuickTime Player folder.

2.Upon reaching their, right click on the Player App. In the shortcut menu, you would find the option of “Properties”.

3.In the option of “Properties”, you would find the tab labeled as “Compatibility”. Simply unchecked the box that says “Run this program in compatibility mode for”.

4.After having done that, apply the modified setting and reboot the system. In this way, appropriate syncing can be achieved and the error can be avoided.

redsn0w 0.9.9b6 fixes Location Services issue for 3GS w/06.15. See #14 is.gd/6eek4Y to re-run it over existing iOS5 JB

Update #14: We’ve released version 0.9.9b6 of redsn0w, with both a functional fix and cosmetic fix for iOS5 jailbreakers. For iPhone3GS owners with the 06.15 baseband, this redsn0w eliminates the network crash you saw when using Location Services in iOS5 (in fact, you don’t even need to disable Location Services anymore during the initial setup). The cosmetic fix is to the visual countdown you see when going into DFU mode.

It’s okay to re-run this redsn0w over an existing device jailbroken at iOS5. Just choose “Jailbreak” again and de-select Cydia (in other words, all the checkboxes will be unchecked). If you are lucky enough to have an old-bootrom iPhone3GS, please pre-select the IPSW first (redsn0w can’t yet auto-detect the FW version of your old-bootrom 3GS if it’s already been jailbroken).
