Downgarde iPhone 4 2.10.04 to 01.59.00 May be Soon !

As most of you know, that iPhone Dev-team is working on two important tasks, untethered jailbreak for iOS 4.2.1 on all iDevices and iPhone 4 baseband 2.10.04 unlock. MuscleNerd has replied via his twitter to someone who asked him about the capability of downgrading iPhone 4, Let's check out how MuscleNerd replied him.

mfaizulislam asking: for Baseband downgrade , can it be applied to iPh4 ?
MuscleNerd replying: conceptually, yep probably. But new i4 unlock must precede that because otherwise, nothing to downgrade from 01.59 to

So, the dev-team is working now on downgrading iPhone 4 baseband 2.10.04 to 01.59.00 which is unlockable using ultrasn0w, but it should be known, that it has not been confirmed the success of this idea so far.

Downgrade 6.15.00 to 5.14.02 / 5.13.04 iOS 4.2.1 After Ultrasn0w 1.2 Soon

Here's a bit of good news for who suffered from the new unlockable baseband 6.15.00 on iPhone 3GS and 3G, most of the unlockers who unlocked their devices with ultrasn0w 1.2 can't restore to any stock firmware above 4.1, it only can be restored to a custom firmware, moreover, ultrasn0w 1.2 caused a loss of GPS. Let's check out the new progress regarding downgrade 6.15.00 baseband.

Lezanz: what about GPS issue? Any progress?
Musclenerd: sorry still collecting data on that. But also working on a bb downgrade (!) method for those with unlockable bb

MuscleNerd: has just confirmed that he is working on a new method to downgrade baseband 6.15.00 to lower versions, which will be unlockable and to fix the GPS issue. Till now we didn't catch more details, but of course will let you know once we catch more, stay tuned.

Downgrade iOS 4.2.1 to iOS 4.1 !

It was possible that you have the curiosity to experiment iOS 4.2.1 GM new features which was released yesterday to iPhone 4, 3GS, 3G, iPod touch 4G, 3G, 2G and iPad, if you still didn't, you can download and jailbreak it now from here. You will note that Cydia still have some issues, the matter which make jailbreak pointless for many.


Moreover the new iOS 4.2.1 GM build has a new baseband version which puts a lot of doubts around the upcoming unlock. Therefore I prepared the downgrade guide from iOS 4.2.1 GM to iOS 4.1, 4.0.2, 4.0.1 or lower.

STEP 1: Download iOS 4.1 or older firmwares for iPhone or iPod Touch.

STEP 2: Put your iPhone in DFU Mode by following this steps,

• Connect your iPhone to your computer.
• Turn iPhone off.
• Start iTunes
• Hold Power and Home buttons together for 10 seconds or so.
• Release Power button but keep holding the Home button until your computer recognizes a new USB device.
• iTunes will now recognize your iPad.

STEP 3: If you are on iPhone 3G or iPod touch 2G (non-MC model) bypass this step. This step is about adding Saurik’s Server address to your system hosts file. This trick make iTunes thinks it is talking to Apple, while it is talking to Cydia while the restoring process.

• Locate "C:\Windows\System32\drivers\etc\" for Windows and "/etc/" directory for Mac, then locate “hosts” file andOpen it in Notepad (for Windows) or TextEdit (for Mac OS X) and add this at the bottom of the file.

At last it will be like that, then save it

STEP 4: Now, You will have to restore your iDevice to iOS 4.1, 4.0.2 or 4.0.1  by clicking on the iPhone icon on the left sidebar of iTunes then hold left “alt” button on Mac (“Shift” button on Windows) on the keyboard and then click on “Restore” then release the alt button, Now Select the iOS 4.1, 4.0.2 or 4.0.1 ipsw file you have already downloaded in Step 1 and let iTunes do some automated Steps.

STEP 5: You will need to exit recovery mode, so download TinyUmbrella (Windows / Mac). Run it and the click on “Exit Recovery” button. Your device will now restart normally.

Now you got back to iOS 4.1, 4.0.2 or 4.0.1 and you can jailbreak your iPhone using our guide posted here.

Yes, you read it write! Now you can downgrade the annoying new iOS 4.0.2 to iOS 4.0.1 or iOS 4, without having your SHSH blobs saved. YES! without SHSH blobs. The tip was sent to us by one of our readers who wishes to remain anonymous, I tried the method on iPhone 3GS and it worked without having your SHSH. Here's how..

Steps :
Step 1: Download the iOS 4.0.1 from here, download iTunes from here.
Step 2: 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 be able to extract.
Step 3: Open buildmanifest.plist file from the extracted files using Notepad (for Windows) or TextEdit (for Mac OS X) Search and replace all – 8A306 with 8A400. Do the same with restore.plist file and save both of them.
Step 4: Now download iOS 4.0.2 and extract it using Winrar or Winzip.
Step 5: Drag all files extracted files from iOS 4.0.1 and replace them with all files of iOS 4.0.2.
Step 6: Delete all ".dmg" files that end with 002 leaving files that end with 001. Then zip the new customized firmware and change it to ".ipsw" file, for example "downgrade.ipsw".
Step 7: This step is option, it helps you to ensure you get an SHSH file request for the future, but should not be necessary to just restore 4.0.1

• Locate "C:\Windows\System32\drivers\etc\" for Windows and "/etc/" directory for Mac, then locate “hosts” file and Open it in Notepad (for Windows) or TextEdit (for Mac OS X) then add this line at the bottom of the file and save it.

• iTunes will now recognize your iPad.

Step 10: Almost done, you will have to restore your iPhone to the firmware you have customized and saved in the above steps by Clicking on iPhone icon that appears in the left of iTunes then hold left “alt” button or “Shift” button on Windows from the keyboard and click on “Restore” then release the alt button. You will be promoted by a window to select the firmware, select your firmware file "downgrade.ipsw" you have made in the previous steps.

Step 11: After series of processes, iTunes will restore your device to the required firmware.

[Thanks Behzad for uploading the files]

Update 5: Well, here's a quick explain why it don't work for all. Users who reported of this method being working for them had at some point in past saved their SHSH files on Cydia, we can't say this method is fake, but it's pretty not working for people who don't have SHSH files on Cydia. Notcom explains on his blog..

There is much discussion on many blogs about a potential means of downgrading iOS 4.0.2 to 4.0.1 by simply changing a couple values in the buildmanifest.plist and copying all of the images from 4.0.1 into 4.0.2 and then deleting the files ending with 002. Following all of this, perform a DFU restore and somehow you will be on 4.0.1.
There is a perfectly logical explanation for all of this and I will lay out exactly what is happening and explain why it is working for the folks that are the lucky ones.
Let me get this out first.

• This is not a miracle, at least not in the sense you all hope for
• SHSHs are STILL required for any iPhone 4, iPhone 3GS, iPad, iPod Touch 3G, and iPod Touch 2G (MC Model)
• There is NO way around this… unfortunately this method included.

Let me start by explaining something very important. The buildmanifest is used by iTunes to build much of the TSS request that is used to obtain your SHSH for any given firmware revision. Unfortunately, the BuildNumber has no part to play in the request for SHSH. All that you ended up doing in following these directions is request 4.0.1 SHSH blobs.THAT IS ALL. Since every single one of you that got this to work changed your hosts file to point to Cydia, Cydia responded to the TSS request with an SHSH blob that was ALREADY "on-file". There was no magic. There was no miracle, apart from the lucky break that your device had been put on Cydia’s SHSH request list at some time in the distant past.
That’s it in a nutshell folks. There was no amazing technique for bypassing Apple’s TSS. There was no amazing exploit that exists in DFU mode allowing for 4.0.2 -> 4.0.1 downgrading. It’s simple; Cydia had your SHSH because at sometime in the past either:

• Someone saved your SHSH with that device using TinyUmbrella and the default options
• Someone restored that device with Cydia in the hosts pointing to gs.apple.com
• Someone jailbroke the device and pressed ‘Make my life easier’

iPhone 3Gs 4.0 downgraded to 3.1.3 Successfully Jailbreak & Unlocked

This thread is for those who where having problem with their iphone 3gs updated to iOS 4.0 heres a better solution

even you were in iOs 4.0 you could still downgrade it to FW 3.1.3 after you've manage to downgrade it you can now unlock it


May be you upgrading to iOS 4 and been slowed down your device and that you want to go back to iPhone 3.1.3 / 3.1.2. Or if you are one of those iPhone 3GS (new bootrom) or iPod touch 3G / 2G (MC model) user who has upgraded to iOS 4 only to find out that you cant jailbreak it can follow the instructions posted below to downgrade iOS 4.0 to (formerly iPhone 3.1.3 or 3.1.2).

Simply Follow these Steps :

Step 1: Download the old iPhone OS 3.1.3, iPhone OS 3.1.2 ipsw firmware files.

Step 2: Put your device into DFU mode (not recovery mode).

• Connect your iPhone to your computer.
• Turn iPhone off.
• Start iTunes.
• Hold Power and Home buttons together for 10 seconds or so.
• Release Power button but keep holding the Home button until your computer recognizes a new USB device.
• iTunes will now recognize your iPhone.

Note:  

Your iPhone screen at this time should be blank (black in color), if not, then you are most likely in Recovery Mode, not DFU mode.

Step 3 is for iPhone 3GS users only. 

Note :
If you are on iPhone 3G or iPod touch 2G (non-MC model), skip Step 3 and continue from Step 4)

Step 3: This step is applicable to iPhone 3GS, iPod touch 3G and iPod touch 2G (MC model) which have their SHSH blobs (ECID SHSH) saved on Cydia for the firmware you downgrading on.

If you don’t have your SHSH files saved, you cannot downgrade the mentioned devices.

So what we will do is to trick iTunes into thinking that it is watching Apple servers, while in real, we are going to change the address to Saurik’s server.

Step 4:
Navigate to C:\Windows\System32\drivers\etc\ and locate “hosts” file.

Step 5:

Mac users can get to “/etc/” directory by going through “Go –> Go to Folder” from Finder.

 Step 6:

• Open this “hosts” file in Notepad (for Windows) or TextEdit (for Mac OS X) and add this

74.208.105.171 gs.apple.com

line as shown in the screenshot below:

NOTE :

for Windows 7 and Vista: Start “Notepad” with Administrator privileges by right clicking on “Notepad” app, and click on “Run as Administrator“ option.

Step 7:
You will now have to restore your iPhone or iPod touch to the firmware you downloaded in Step 1.

Click on your phone icon from the sidebar in iTunes.
Now press and hold left “alt” (option) button on Mac (Left “Shift” button on Windows) on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release this button.

This will make iTunes prompt you to select the location for your downloaded firmware file. Select that ipsw file and click on “Open”.

Step 8:
Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs firmware on your iPhone or iPod touch. Your iPhone screen at this point will be showing a progress bar indicating installation progress. Now at some point, iTunes will throw 1011, 1013 or 1015 Errors see our posted here how to fix them. This is normal, just ignore this error as the firmware has already been successfully installed on the device.

Step 9:

 Now you will need to exit your device from Recovery Mode. To do this, download a program called RecBoot (Windows / Mac) or  RecBoot (Windows) - RecBoot (Mac). or our RecBoot  Guide Posted Here
Run it and the click on “Exit Recovery Mode” button.
Your device will now restart normally.

Full Guide : Downgrade iOS 4 iPhone 3GS, 3G and iPod touch to iPhone 3.1.3 / 3.1.2 ( video )

May be you upgrading to iOS 4 and been slowed down your device and that you want to go back to iPhone 3.1.3 / 3.1.2. Or if you are one of those iPhone 3GS (new bootrom) or iPod touch 3G / 2G (MC model) user who has upgraded to iOS 4 only to find out that you cant jailbreak it can follow the instructions posted below to downgrade iOS 4.0 to (formerly iPhone 3.1.3 or 3.1.2).

Step 1: Download the old iPhone OS 3.1.3, iPhone OS 3.1.2 ipsw firmware files.

Step 2: Put your device into DFU mode (not recovery mode).

• Connect your iPhone to your computer.
• Turn iPhone off.
• Start iTunes.
• Hold Power and Home buttons together for 10 seconds or so.
• Release Power button but keep holding the Home button until your computer recognizes a new USB device.
• iTunes will now recognize your iPhone.

Note:  

Your iPhone screen at this time should be blank (black in color), if not, then you are most likely in Recovery Mode, not DFU mode.

Step 3 is for iPhone 3GS users only. 

Note :
If you are on iPhone 3G or iPod touch 2G (non-MC model), skip Step 3 and continue from Step 4)

Step 3: This step is applicable to iPhone 3GS, iPod touch 3G and iPod touch 2G (MC model) which have their SHSH blobs (ECID SHSH) saved on Cydia for the firmware you downgrading on.

If you don’t have your SHSH files saved, you cannot downgrade the mentioned devices.

So what we will do is to trick iTunes into thinking that it is watching Apple servers, while in real, we are going to change the address to Saurik’s server.

Step 4:
Navigate to C:\Windows\System32\drivers\etc\ and locate “hosts” file.

Step 5:

Mac users can get to “/etc/” directory by going through “Go –> Go to Folder” from Finder.

 Step 6:

• Open this “hosts” file in Notepad (for Windows) or TextEdit (for Mac OS X) and add this

74.208.105.171 gs.apple.com

line as shown in the screenshot below:

NOTE :

for Windows 7 and Vista: Start “Notepad” with Administrator privileges by right clicking on “Notepad” app, and click on “Run as Administrator“ option.

Step 7:
You will now have to restore your iPhone or iPod touch to the firmware you downloaded in Step 1.

Click on your phone icon from the sidebar in iTunes.
Now press and hold left “alt” (option) button on Mac (Left “Shift” button on Windows) on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release this button.

This will make iTunes prompt you to select the location for your downloaded firmware file. Select that ipsw file and click on “Open”.

Step 8:
Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs firmware on your iPhone or iPod touch. Your iPhone screen at this point will be showing a progress bar indicating installation progress. Now at some point, iTunes will throw 1011, 1013 or 1015 Errors see our posted here how to fix them. This is normal, just ignore this error as the firmware has already been successfully installed on the device.

Step 9:

 Now you will need to exit your device from Recovery Mode. To do this, download a program called RecBoot (Windows / Mac) or  RecBoot (Windows) - RecBoot (Mac). or our RecBoot  Guide Posted Here
Run it and the click on “Exit Recovery Mode” button.
Your device will now restart normally.
