Redsn0w 0.9.15b2 iOS 6 Tethered Jailbreak Released

iOS 6 Tethered Jailbreak Released - Redsn0w 0.9.15b2 For iPhone, iPod And iPad

It has been a while since we had iOS 6 on our devices and waiting desperately to jailbreak the device and get Cydia working on them to install various tweaks and to theme up the device. iPhone Dev-Team has released redsn0w that can provide a tethered jailbreak for iPhone 3GS and iPhone 4. The jailbreak works is only for A4 devices and should not be tried on A5 devices like iPhone4S and beyond. This version of redsn0w also bring a relief for those iPad 3 users who have been waiting for restore option on iOS 5.1.1. Redsn0w now allows A5 devices to re-restore their devices back to iOS 5.1.1 on the condition that the device is still on iOS 5.1.1 and that the shsh blobs are saved for that device. The following are the features of redsn0w 0.9.15b2
  • 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-to’s 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 haven’t done so yet. Resubmitting is okay and won’t cause conflicts.
More Features

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 don’t 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, it’s the “wrong kind” of ramdisk (you’d 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)
  • It’s 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 don’t 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 can’t (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 didn’t come with the original firmware
  • Stay away from this if you have an unofficial unlock that isn’t 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 you’re 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 (they’re the only A5+ devices that ever had a public 4.x FW)
  • Redsn0w still supports (but doesn’t 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. It’s always much faster to jailbreak those FW versions with a freshly-restored device, before letting iTunes restore from a saved userland backup.

5. ultrasn0w isn’t 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
  • Still, IMEI-based unlocks don’t work in all cases. We’ll 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 you’re 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 you’re 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

New Redsn0w 0.9.14b2 iPhone 3GS 6.15 Baseband Downgrade Released

Redsn0w 0.9.14b2 Updated To Fix iPhone3GS 6.15 Baseband Downgrade - Download Now


The iPhone Dev-Team has just announced Redsn0w 0.9.14b2 which is an update to the existing version of redsn0w that allows users to downgrade the iPad 6.15 baseband. Following the issues with various iPhone3GS users, musclenerd has looked into it and finally released an update to the Redsn0w. The new Redsn0w should fix all downgrade issues and will also help users with broken iPhone buttons to enter DFU mode without having to follow the button instructions.

The iPhone Dev-Team has also provided the revised steps to successfully downgrade iPhone3GS 6.15 baseband. It goes like this:
  1. Connect your iPhone in normal mode, then click “Jailbreak” after redsn0w identifies its model and BB version (you needn’t pre-select the IPSW anymore).
  2. Choose the “Downgrade from iPad baseband” option (you needn’t worry about de-selecting Cydia anymore).
  3. Do a controlled “slide to power off” shutdown of your phone and proceed through the normal DFU ramdisk steps.
IMP : iPhone3GS which were manufactured in early 2011 are not compatible. They have a NOR chip that cannot be upgraded to 6.15 and trying to flash the iPad baseband will brick your device.


This version of Redsn0w is much relieving for those iPhone users who have their buttons broken and cannot enter the DFU mode following the general instructions. To enter DFU mode on a broken iPhone:
  1. Launch Redsn0w
  2. Go to   Extras->Even More>DFU IPSW 
  3. Select the ipsw that is currently been signed for your device or for which you have shsh blobs saved.
  4. Redsn0w will create a ENTER_DFU IPSW that you can install with iTunes and once the installation is complete you'll enter into DFU mode.

Updated Redsn0w iPhone3GS 6.15 Baseband Downgrade Tool To Release Today - Musclenerd

Updated Redsn0w iPhone3GS 6.15 Baseband Downgrade Tool To Release Today - Musclenerd


New Redsn0w Announced : Download

A week ago, Musclenerd from the iPhone Dev-Team confirmed that there is a third kind of flash NOR that caused problems for some iPhone 3GS users when trying to downgrade the iPad 6.15 baseband. This resulted in redsn0w showing that baseband downgrade was successful but when the iPad reboots after baseband downgrade attempt, the baseband was unchanged. After quite a  lot of research musclenerd via twitter confirmed that an update to redsn0w will be released to fix all the errors. He also confirmed that changing the payload would fix the issue.

Today Musclenerd announced over twitter that an updated version of Redsn0w iPhone 3GS baseband downgrade tool would be released. This updated version of redsn0w will work on those devices which were unable to downgrade the 6.15 baseband. However, musclenerd has also confirmed that this version of redsn0w will not support those devices which could not initially get 6.15 baseband ( newer devices ). He mentioned that the revised payload seems to work fine on the devices that were unable to downgrade earlier.

Here is what he said:


Musclenerd claims to have found a way to change the IMEI of the iPhone3GS. According to him that was the reason causing iPhone users to have no signal because of no reason and the only plausible reason was IMEI. Changing that would apparently fix the signal issue. Also, IMEI changing is considered as illegal in many countries and is punishable by law. The iPhone Dev-Team will not and never release any tool that allows unethical behavior and beaks any laws. When asked if the IMEI changing tool would be released, musclenerd simply mentioned that it is illegal in many countries to change the IMEA and that it would be a bad idea to release such a tool.

iOS6 Beta2 Released - Redsn0w Updated To Jailbreak iOS6 Beta2

iOS6 Beta2 Released - Redsn0w Updated To Jailbreak iOS6 Beta2
Apple has pushed an update to iOS6 Beta by releasing the next version, beta2. If you are an Apple developer, you can log into your Apple developer account and then access the iOS page to download and install iOS6 on your iDevice. iOS6 fixes some known bugs and there are certain compatibility patches. There has been no significant change in iOS6 beta 2 compared to beta 1.

Having said that, iPhone Dev-Team has announced an update to Redsn0w to jailbreak iOS6 Beta 2 along with a bug fix that caused SSH problems and crashes with apps that users have been reporting. If you are a developer or if you already have access to iOS6 and would like to jailbreak your device, you can download and use redsn0w 0.9.13dev2 which is the most recent update. Jailbreaking instructions are quite similar and if you are unaware of how to jailbreak then you should probably stop reading this post and should never install iOS6 beta on your device because you might be risking your device.  If you are wondering how to jailbreak iOS6 beta2, all you have to do is to point redsn0w to iOS6 beta 1 and this will help you get a tethered jailbreak. REM : This version of redsn0w is a tethered jailbreak which means every time your device restarts, you will not be able to return to the lockscreen and will get stuck on the Apple boot logo until you connect your device to redsn0w and run tethered boot.

iOS6 brings many new features to iPhone and iPad and the most amazing feature of iOS6 is that it will have 3D TomTom maps instead of Google maps, we have already seen the preview of 3D maps during Apple's world wide developer conference (WWDC2012) that was held during June 11-15 inviting developers around the word to share the future of Apple. Another major improvement was seen in Siri, which has now become smarter, and wiser. Siri can now talk about sports and with the help of various mergers and partnership, Siri will also show the movie reviews and will rate the restaurants based on their service. During the launch, it was mentioned that iOS6 has over 200 new features that are interactive and will enhance the user experience as Apple always wanted.

Musclenerd Talks About iPhone3GS 6.15 Baseband Downgrade Failure

Musclenerd Talks About iPhone3GS 6.15 Baseband Downgrade Failure


Update : Happy 4th July - Updated Redsn0w To Fix Errors Releasing Today

Earlier this week, the iPhone Dev-Team announced the release of updated Redsn0w that allowed iPhone3GS and iPhone3G users to downgrade their baseband from that of iPad's 6.15.00 to 5.13.04 allowing them to unlock their device using ultrasn0w and getting back the GPS for iPhone3GS users. Redsn0w worked for some but many users faced difficulties in downgrading the baseband. Even after the process completes the baseband for a majority of people was still 6.15 which indicates that Redsn0w actually din't downgrade the baseband to 5.13.04.

Many troubleshooting methods were discussed but eventually there wasn't any optimum solution available to downgrade the 6.15 baseband. Senior members of iPhone Dev-Team even suggested of performing a fresh restore and then reflashing of 6.15 baseband and then attempt to downgrade. This did not help either.

Musclenerd Confirms Redsnow Update

Musclenerd today announced on twitter that he has discovered the reason for baseband downgrade failure in many iPhone3GS. According to him, the reason for failure of baseband downgrade is because of variation in NOR chip which can be changed to handle the differences between the NOR chips. There are altogether 3 types of NOR. Two are very similar and the third one is entirely different which was left out in the Redsn0w. Lastly Musclenerd clearly mentioned that he needs a loaner iPhone3GS which he'll be getting by Thursday and once the testing is done, a redsn0w update will be pushed that will allow all iPhone3GS users to downgrade their baseband without any errors. Hopefully by the end of next week every iPhone with 6.15 baseband will be successfully downgraded.



To Wrap Up
  • Reason for baseband downgrade failure was variation in the NOR chips
  • There are 3 different models of iPhone3GS with different Nor chips.
  • Two of them are similar but the third one is entirely different, probably the one left out in Redsn0w
  • Musclenerd confirmed an update to Redsn0w next week after Thursday.

Q) How do I check if my iPhone is supported or not
A) If redsn0w 0.9.14b1 din't work on your device, its better to wait until next week for redsn0w update

Q) Will the updated redsn0w support all iPhone3GS models ?
A) Hopefully, yes. After reading RCE of Apple's 3GS flashers for a while, musclernerd observed that there are not 2 but 3 NOR chips.

Q) What is this NOR chip ??
A) NOR flash memory is used to store configuration data in iPhone.

How To Downgrade iPhone3GS 6.15 Baseband Using Redsn0w

redsn0wbbdowngradeThe iPhone Dev-Team as promised has released an updated version of redsn0w that will allow iPhone3GS and iPhone3G users to downgrade their device's iPad baseband 6.15 which was performed in order to unlock the devices. This however casued certain unexpected issues like battery drainage and loss of GPS in iPhone3GS. It was mandatory to flash iPad's 6.15 baseband on iPhone3G and 3GS as that was the only unlockable baseband that could be unlocked using iPhone Dev-Team's Ultrasn0w unlock. Musclenerd made an announcement earlier that a tool will be released in future that would allow the possibility of downgrading iPhone3GS and 3G basebands to an unlock-able version.

Having said that, today the iPhone Dev-Team proudly announced the release of updated Redsn0w that allows the users to downgrade their basebands. Since playing with basebands is not cool, we decided to prepare an easy to follow instructions guide to downgrade 6.15 baseband.

Update 1 : Musclenerd Confirms iPhone3GS 6.15 Baseband Downgrade - Redsn0w To Be Updated Soon

Update 2 : Happy Independence Day - New Updated Redsn0w Releasing Today

Steps To Downgrade iPhone3GS & 3G 6.15 Baseband

Step 1 : Download the latest version of Redsn0w and the current firmware of your device

Step 2 : Extract the contents of the Redsn0w archive that you just downloaded.

Step 3 : Connect your iPhone3GS or 3G and Launch Redsn0w.
(Windows7 users should select the option of running as administrator by right clicking on redsn0w application and then selecting the option - Run as administrator)

Step 4 : In the redsn0w, go to extras menu


Step 5 : From the extras menu, select 'Select IPSW' option


Step 6 : Navigate to the folder where you download the current firmware of your device and select the firmware and click open.

Step 7 : Click Ok to confirm the firmware selection

Put your device into DFU mode

Step 9 : Now go back to the main menu and select the option 'Jailbreak'

Step 10 : The jailbreak process will begin and then Redsn0w will show more options where you need to select 'Downgrade From iPad Baseband' and then click next.

Step 11 : Put your device into DFU mode
  • Power off the device completely
  • Hold power button for 3 seconds
  • without releasing the power button, press and hold home button for 10 seconds.
  • Now release the power button and continue holding the home button .

Redsn0w will use limera1n to exploit your device to enter into pwndfu mode. Once done, continue with the steps. Redsn0w will now start processing your device's build


Step 12 : Redsn0w will now inform you that the rest of the process will happen in your device.

Step 13 : Your device should show some scrolling text and then you should be able to see the pineapple logo indicating 'Flashing Baseband (don't interrupt). Its serious, don't unplug or do anything stupid or you'll never be able to use your device again.


Step 14 : Once done, your iPhone will reboot and you should have 5.13.04 baseband.
