monkey_duster

I hope it will be applicable to an iPhone 4 with a 2.10.04 BB. thank you dev team for all the efforts!

iPhoneHacks

Dev Team hasn't provided any update on the unlock for iPhone 4 baseband other than saying it will need more efforts. We will keep you posted if we have any news on that front.

davidj

thanks so much DEV...for the new 3gs comers, after the new solution come out, can we jailbreak and unlock the 3GS with IOS 4.1 and BB 5.14.02 with this new solution without upgrading the new BB and downgrade back to 5.15.xx?

Looking forward to this. I miss my GPS. Great work!

I'm trying to unlock my iPhone 3GS (old bootrom) and it keeps going into dfu mode. I've tried redsn0w and I've tried booting it *tethered* but it still won't boot and stays in recovery mode. I've been trying to use the pwngetool also but it does not give me the option to fetch the iPad 3.2.2 firmware so I can unlock. IDK what the problem is and it won't even let me restore to an official firmware bundle (it's running iOS 4.2.1/4.2). What can I do. I've been up all night pulling my hair out here!

I'm having trouble with Facebook. My wife keeps getting Facebook notifications if foreign languages. (German, Japanese, Russian, and Spanish so far.)

Yes please! Downgrade would be of great help. Even it is not possible to unlock.

ok mk

I'm assuming that you have the proper ipsw downloaded for your iPhone? Maybe double check first.When I did it to my 3GS i actually did it in different steps using redsn0w 2 separate times. Try to Flash the iPad BB first, then install Cydia separately. If you're using pwnage tool, make sure that you downloaded the newest version. They released a special Unlock Edition just for the 6.15 BB unlock, but you must also download the iPad 3.2.2 FW ipsw if you are using Pwnage tool.Hope that helps.

why i cant update to 4.2.1 after i JB and flash the bb 6.15 on my 3g? help!!

Gee

Sounds good but I'm not having any issues right now with GPS. Currently have 3GS OS 4.1, BB 6.15 unlocked on T-Mobile and all is good. Would probably look at downgrading only if there were an issue. I had my original SIM card from ATT from a while ago and that activated it so I'm not having any GPS or battery issues.

Thanks DEV team, you're the BEST of the BEST.

HEY

Gee, how did you do it? I am scared of upgrade to 6.15 and have multiple problems. I have 3gs, 4.1, 5.14.02. Its JB with snowbreeze already have cydia.Was using ATT now Im trying to get T-mobile.thanks in advance...

Gee

I just followed the instructions and believe me, I'm new to this whole thing. I downloaded the 4.1 and 4.2 and ipad ipsw's like they said and then I ran redsn0w. When prompted I pointed to the 4.1 ipsw because I wanted to keep my untethered jailbreak if possible and it went through just fine. Then loaded the ultrasn0w unlock and it was ready to go. I used my old ATT SIM to activate it and then I put the T-Mobile SIM in and it works fine. GPS and battery are not an issue as I believe it's only an issue with 4.2 and anyone who didn't activate with SIM card. Like I said, I'm new to this and I did it so follow the directions and you should be fine. Make sure to use the utilities to backup your phone just in case.

sdguy

I still have GPS after unlocking my 3GS (old bootrom) on bb06.15 buy it is usually 2 to 3 miles off. If the downgrade keeps my phone unlocked, would love to downgrade. Otherwise, love a fix to the GPS issue. Good luck guys. You always do great work.

HEY

Gee, Im sorry but I am already on 4.1. Should i proceed with the IPSW ipad download then run redsn0w?

Munaf

i dont understand one thing if the dev team have not retested their new baseband then why they release i meam why the **** they are creating a big scene that they got a solution for iphone unlock.dev team first find the right unlock thats 5.15.01 and then do party

Gee

I was also on (and still am) on 4.1 but you need to download that as well as the iPad ipsw. Part of running the redsn0w it will ask you for your ipsw of the OS YOU ARE ON NOW and that's where you need to point to the 4.1 ipsw. then a little later during the install it will ask you where the iPad ipsw is so you need both before you move forward. I think that first step is the important one to stay on 4.1 and have the untethered jailbreak. if you (or anyone else) accidentally points to the 4.2 ipsw you'll end up on 4.2 where you don't want to be. Just make sure you have both the 4.1 and ipad ipsw and you should be all set.

HEY

Thanks man, I will let you know how'd it go. Hopefully it works for me.

try Ireb!

u cant do a update after using 6 15

Ray

I HAVE CREATED A METHOD FOR UNLOCKING ANY BASEBAND ON ANY iOS FIRMWARE EMAIL ME @ poppin3000@yahoo.com for intructions

cshankar

its possible that your iphone baseband upgraded to 6.15 but since you are restoring to 4.2.1 itunes will not let it restore. I suggest that you try downgrading to 4.1 ipsw and then use iRecovery or iReb to kick out of recovery. If it works, then pl do not upgrade to 4.2.1. I had the same problem and downgrading to 4.1 ipsw and using iReb solved my issue. Took me 2 days to figure this out though.

Hello Guys, I am having a problem here with my Iphone 3gs on IOS 4.1 and FW 5.14.02. serial # indicate that i have a old bootrom, but when i ran redsn0w during the process it prompted and said that i have a new one even though i had selected that i have a old one by checking the serial # in my device. 4th # is a 3 follow by a 1. Anyone?

Why is there so much attention to the 3G and 3GS? Why dont they bother about the 4?
