Can I fix 3gs jailbreak via sn0wbreeze upgrade

[justinbloom]

I recently jailbroke my 3GS phone using blackra1n. My firmware was 3.1.2. After the jailbreak I installed cydia and unlocked my phone. Then I tried to start cydia but it crashed on the first try. I was connected to AT&T via 3G and not wifi. I think this might have caused the crash. I never got it to load and rock doesn't work either. All of the fixes I have seen require using SSH which I can't install without cydia.

I tried reinstalling 3.1.2 planning to rejailbreak and iTunes won't allow it. I then tried to install 4.02 and an error occured.

What I want to try at this point is to install a custom 4.2.1 firmware created using sn0wbreeze with cydia and ssh already installed. I am afraid to jump the gun because I don't want to mess things up more. Should this work? Can I install the custom firmware since my phone is jailbroken? Is it ok if it preserves my baseband at 5.11.07? Will my phone stay unlocked?

Thanks so much... Justin

Just in case anybody has this same question, I used sn0wbreeze and would recommend it to anyone! It did an amazing job! My phone is much more stable now than it was after blackra1n. Everything is now working as it should. Cydia comes up just fine. I also have open ssh installed now too, though I haven't tested it yet. It also fixed a problem I was having with my wifi. I am also excited to have a v4 firmware now.

I am not sure if I needed to do the blackra1n jailbreak first. Maybe somebody can explain this to me. I know sn0wbreeze installed a custom firmware, but I don't know if it does the jailbreak also, or if it it only works on a phone that is already jailbroken.

I am also impressed that sn0wbreeze was able to preserve my baseband at 5.11.07. I previously unlocked my phone using blackra1n. I am assuming that my unlock was preserved, though I have not tested this either.

If I am making false statements, I apologize. I am new at this. All I know for sure is that after using sn0wbreeze I have a working jailbroken phone with 4.1.2 firmware and 5.11.07 baseband and everything is working amazingly well.

Thanks to ih8tsn0w!

Well. I'm glad you got everything working out for you

What sn0wbreeze's job is to create that custom firmware which will let you preserve that baseband (of course you knew that since you took that route), but the blackra1n jailbreak prior to that doesn't matter much, because if you used the DFU instructions embedded into sn0wbreeze, it would put your phone into a pwned state, which would accept the custom firmware.

As for it doing the jailbreak, it does the jailbreak only if you want it to. sn0wbreeze was recently given the feature of "Baseband Preservation Mode", which makes you a custom firmware which removes the baseband update bit of the firmware, but it also doesn't jailbreak the phone. So it's like having a stock firmware without the updated baseband, intended i'm assuming if someone wanted to jailbreak with a different program (i.e. limera1n/greenpois0n)

am i missing something?

why are you unlocking your phone when your carrier is AT&T?
