cannot unlock my iphone 3G // Baseband 05.12.01

[aldorande]

Hi,

I have downloaded and installed Blackra1n RC1, and that doesn't work: that just display some empty dashes instead of bars for the Network.

this is my current config

Firmware 3.1.2 (7D11)
Modem Firmware (baseband) 05.12.01
iTunes 9.1 on Mac OS 10.6.3

Is there any other software that could fix it? how do I get it on my iPhone?

Or do I have to do some complex manipulation with downgrading the firmware? what are they exactly?

Thanks a lot.

There isnt an unlock tool for baseband 05.12.01.
Your phone must have been updated to 3.1.3 FW which installs a new Baseband. Even when you downgrade FW, the baseband will not change back.

FYI, blackra1n would have only JB your phone, not unlocked it, so not sure why that didn't work.

If you still want a JailBreak, maybe try blackra1n RC3 or redsn0w, whatever its latest version is.

hi pixelated,

thanks for your answers.

my iPhone has just been jailbroken using Pwnage Tool 3.1.5. Blackra1n was not working: it tells my iPhone is jailbroken but kept displaying the screens Connect to iTunes / Emergency Calls (which probably wouldn't work, would they?).

Now my iPhone is working except the Phone feature. I need to unlock my phone. Are you sure there is no way?

well, if your 3G was one of the first made there is a VERY SMALL chance you will have a bootloader for which there is a baseband downgrade.
Heres an iClarified Tutorial on the how to, but don't get your hopes up.

To be clear, if Fuzzyband does not allow you to downgrade your baseband, there is no way for you to unlock your phone.

 

[aldorande]

Fuzzyband Downgrader 1.0 says it's Not supported. It shows Bootloader Version and Baseband version being 0.00.

However, it's just written in red bellow :
This software cannot be used ton iPhoneOS 3.0; You must downgrade to 2.2.1 or lower.

What does this mean?

 

[aldorande]

any ideas?

 

[thelatinist]

You cannot unlock your phone. Sorry.

Not possible at the moment.
Sorry.

 

[aldorande]

and now?
isn't RedSn0w able to do it?

I have the same config as before except that I have iTunes 9.2. (10.6.4)

Yes, if you're on 4.0 just run redsnow to JB it.
And then install ultrasnow from cydia to unlock it.
Or if you want you can stay on 3.1.2 and just install ultrasnow from cydia.

thanks that worked with Ultrasn0w: I can phone from Meteor provider now
