How to Upgrade Your iPhone 4, 3GS Without Updating the Baseband (Mac)
Comments

Is there a way to use this method with a broken Home button? Thank you.

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?

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"

Can I use this method to upgrade my 3gs from iOS 4.1 to 6.x ? My iphone is running still BB 5.13.04 and I think I have to keep this BB to stay unlocked ?! I have iphone 3gs new bootrom, AT&T unlocked and jailbreaked via redsn0w running iOS 4.1 Thanks !

i have an iphone 4 and i follow the instruction but i am stuck in DFU mode, can someone help?!!

I know how to get out of the DFU mode, I just need to know why the update is not working....

iPhone 4 with baseband 03.10.01 with gevey sim unlock.. will this work?

will this method work for the iphone 4s?

does anyone know If I have iphone 4, baseband 01.59.00 would i still persevere my baseband if i follow these instructions correctly?

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!

I have iphone 4, baseband 01.59.00 would i still persevere my baseband if i follow these instructions correctly?

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?

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).

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

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

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.

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

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.

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

on mac this process is working great

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?

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

did your gevey sim still worked?

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 ?

Ultrasn0w isn’t 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”

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

anyoane tested this ?

whats the point in this? just pay $4 to get it factory unlocked

dude stfu an unlock for an iphone 4 is between 50$ and 200$ have anyone tried this on an iphone 4 ?
