These are instructions on how to upgrade your iPhone 4 or iPhone 3GS firmware without updating the baseband.

Step One
Create a folder on your desktop called Pwnage

Download the latest version of RedSn0w from here and place it in the Pwnage folder. Likewise, download the firmware you would like to upgrade to from here and place it in the Pwnage folder.

Extract the RedSn0w zip file by double clicking it.

Click Extras from the RedSn0w menu.

Step Four
Click Even More from the Extras menu.

Step Five
Click the Restore button from the Even More menu.

Step Six
Click the IPSW button.

Choose the firmware you would like to update to from the dialog box that appears and click the Open button.

Step Seven
You will be asked if you would like to Prevent baseband update. Click the Yes button.

Step Eight
You will be told that Pwned DFU mode is required. Click the OK button.

Step Nine
Connect your iPhone to the computer, turn it off, and click Next

Step Ten
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here.

Hold down both the Home button and the Power button for 10 seconds.

Release the Power button and continue holding the Home button until RedSn0w detects the device.

Step Eleven
Your device will be detected once in DFU mode and exploited with Limera1n.

Redsn0w will then prepare a restore image.

Step Twelve
Redsn0w will now restore the device to the new firmware.

Step Thirteen
RedSn0w will tell you when the restore has been completed successfully.

can I use this method with my iPad 2 , I am running 6.1.3 ???

Great news guys! If you iPhone is locked by AT&T and you bought it 2 years ago it can be Factory Unlocked now! Just contact AT&T from the following link: https://www.att.com/deviceunlock/client/en_US/termsAndCondition I did it and it is free and fast! Forget about Ultrasnow/Gevey and preserving your baseband, this is the real jailbreak, haha! iclarified should post this info in every post!

iPhone 3GS on 3.1.3 baseband 5.12.10 tried this & it asks for shsh. My cydia crashed months ago so I deleted it and don't know how to reinstall it to see my shsh or get them or whatever I'm supposed to do. Ive been in safe mode for 2 months but everything seems to work. I just want to go to 4.3.2 or 5.0 because most apps require it. Any help would be enormously appreciated.

I am trying to upgrade to 6.1.3 from an iPhone 4 on 5.0.1 with BB 01.59.00 and got Unexpected Error 2831. I tried fixing it holding Home Button through all the process, I didn't get the error but Redsnow never finished and I got stucked on Recovery Mode (itunes logo). Any ideas how to fix it?

009 - May 19, 2013 at 2:49am

I also got "Couldn't restore" "Unexpected error (2831)" and my phone came back on just the way it was before I began. I'll keep scoping this out to see if there's a fix. I will also try using firmware 6.0 instead of 6.1.3 and see how that goes. I'm running iPhone 3GS 4.2.1 Modem Firmware 5.13.04. Thanx

When i finished this process i ended up with the 'connect to itunes logo"

jeibi - October 31, 2012 at 4:31am

if you are using IPHONE 4 running at 5.0.1 at 4.11.08 baseband and you followed these steps ACCURATELY, you have no problems after. Did every step and now I have a preserved baseband running at IOS 6 :) Thanks bud! Your steps were AWESOME! KUDOS!

Hamza - November 6, 2012 at 10:32pm

Hello, i have an iphone IOS 4.3.2 Baseband 4.10.01 (Factory Unlocked using gevey sim) . and how can i update it to IOS 6 without upgrading my Baseband? and If i successfuly Updated it to ios 6 and preserved my baseband, can i still unlock it with my gevey sim?

thefakeburrito - October 30, 2012 at 4:48pm

If you got an iPhone 4 or 3GS, you can follow this guide step by step, it's pretty easy. I don't think there'll be a problem if you update multiple firmwares at once (since you are in 4.3.2). Update here to iOS 6, then jailbreak it (you can find another guide here in iClarified).

yaku - November 4, 2012 at 3:28am

hey.. did you update using this method? and your gevey sim still worked?

jb - October 28, 2012 at 4:29pm

after getting it into DFU mode, its asking me for shsh blobs, local or remote, i clicked remote and it couldnt find them and i dont have any local ones, what do i do? im an iphone 4 on 4.3.5 with 4.10.01 trying to upgrade to 5.1.1

jj - December 18, 2012 at 4:51am

Having the same problem here. I'm on a 3GS, iOS 4.1, 04.26.08 firmware. If I try to use any higher iOS ipsw, it asks for SHSH blobs that I don't have and it can't find remotely.

jj - December 27, 2012 at 9:18am

The same to my. It ask me to use local/remote Blobs to restore. UGRRR

JJ - December 27, 2012 at 5:02pm

What finally worked for me was finding a list of what iOSes redsn0w could remotely find blobs for, THEN downloading the right ipsw and successfully getting remote blobs for it. I ended up on 5.0.1.

pedro - December 30, 2012 at 7:23pm

had same problem the only thing that work was to create a custom firmware with snowbreeze on windows.

steve - October 18, 2012 at 11:14am

thefakeburrito - October 16, 2012 at 4:15am

It worked pretty cool to me, I have an iPhone 4 (GSM) and I use the gevey sim: everything fine, but, it didn't install cydia any ideas..? please?

thefakeburrito - October 16, 2012 at 4:34am

Well, uh, I think this tutorial is about "How to Upgrade Your iPhone 4, 3GS Without Updating the Baseband" and not jailbreaking it... correct me if I'm wrong, but, mmm, yes

yaku - November 4, 2012 at 3:30am

vipul1614 - October 15, 2012 at 12:14pm

i juz update my iphone 3gs without updating the baseband i.e 5.13.4.........after restore and jailbreak there is no carrier section in settings....cydia is working fine...i also install ultraslow 1.2.7 but still no service.....help me ?? wat to do ?

Victor - October 15, 2012 at 5:26pm

Ultrasn0w isnt yet updated for 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

sompopo - October 16, 2012 at 3:04am

open cydia and look for a program call tetherme install it problem fix

mark - October 14, 2012 at 11:29am
