Edit: Solved as a tethered JB via RedSn0w

Thanks for all the help!!

Hey guys,

quick question:

Got myself a 3GS (week 47, bootloader 05.11.07), locked to german T-Mobile.

When attempting to jb it with redsn0w, i sent it to recovery mode, it which its stuck now.

As itunes won't allow to downgrade back to 3.1.2 i was wondering if i could pwnage to 3.1.3 and have the bootloader unchanged, so i could go for blacksn0w after.


Would that be possible?
Are there alternatives?


Cheerio,

dP


Edit:

Just to clarify: Installed firmware is prior to 3.1.3.

Did you answer incorrectly in redsn0w regarding "late model device?" question? You should have answered yes. If you answered incorrectly to that, it is likely you can't use pwnagetool/custom ipsw to solve your problem.

You have a fundamental misunderstanding regarding the right terms. A quick lesson.

Baseband: the OS for the radio part of your phone (making calls, SMS, wifi etc) this is often updated with new iPhone OS releases. iPhone OS 3.1.2 came with baseband 05.11.07 and iPhone OS 3.1.3 comes with 05.12.01

Baseband cannot be downgraded on the 3GS, only upgraded.

Baseband Bootloader: the bootstrap for the baseband OS, it checks that the baseband is valid and then loads it, passing control over to the baseband OS once it is loaded. It is possible for this to be updated in a new iPhone release but it has not happened since the OS 1.0.x days. So nothing to worry about here.

Man, i really appreciate the time and efford you put in here for helping other users.

I am educating my self as we speak/type, but it doesn't seem to bring closer to my goal of unlockin that 3gs b*tch.

I used redsn0w, chose "YES" when it asked for new model and ended up in a loop that sent me to recovery mode.

By using blackrain on a Win7 machine i managed to break the loop. When i tried to start cydia, it started, closed itsself and then the icon dissapeared for good (among with some others like AppStore or Compass).


So i am stuck again now... redsn0w again?

I only live in Norway, not norwegian.

Do this to find your iBoot version and your ECID both are very useful to know.
I only want to know about the iBoot version - you need to know the ECID so you can backup your SHSH or see if there is anything on Cydia already for you.

PwnageTool 3.1.4 for Mac OS X

Did you restore in between using redsn0w and blackra1n?

What version of redsn0w and blackra1n did you use?

Okay man, i will try as you said.
Tbh, i was soooooo happy to get out of DFU again but i will go in again

iBoot-359.3.2

... as for the ECID and Cydia: Still no icon

Did NOT restore between RS & BR and used the latest versions of both out.

What passage would you suggest now?

Thanks again,

For redsn0w, I need the specific version 0.9.4 is the latest version but it is a beta version only intended for 2G iPod touches with model numbers beginning with MC. So "latest version" is not always so helpful.

My bad, sorry.

Meant the latest final i know of:

redsn0w-mac_0.9.2.

Did you get your ECID earlier when you checked the iBoot version?

Have you used the Firmware Umbrella to check if Cydia has a 3.1.2 SHSH for your ECID?

Yes, Umbrella states there is no ECID SHSH for my model on Saurik/Cydia



Edit: Though surprisingly i get an SHSH for my ECID when i choose 3.1.3 instead of 3.1.2.

That is because if cydia can't find a SHSH it passes the request through to Apple and apple is still signing 3.1.3

I am not sure what to recommend for you. You have a strange situation. You are running OS 3.1.2??? Not 3.1?
