Hi all,
obviously my first post it's a problem solving request

I've an american iphone 2G 8GB jailbroken&unlocked with redsnow to OS 3.0.

Missclicking I've updated it to 3.1 via iTunes (Yes, I know I'm a noob ).

Anyway I re-jailbroke it but "phone part" doesn't work.

I know that is a baseband upgrade issue: I tried to downgrade it but fuzzyband doesn't work (it stops on modem querying) and if I try to check my bootloader I've the result Unknown or none (using terminal).

At the end now I've a pretty Ipod touch

Someone can help me?

Thanks

PS: sorry for my bad english but I'm not native speaker

baseband is not the probem on 2G
just downgrade it from 3.1 to 3.0 and re-jailbreak&unlock

if you want upgrade the FW you must upgrade it with pwn tool 3.1/higer
and it wil be unlock it too

I jailbroke to 3.1 on pc with iTunes 9.0 + custom firmware but it doesn't work.

I tried to downgrade to 3.0 ( iTunes 8.2 firmware restore + redsnow 8.0 jailb&unlock) but it doesn't work.

Any suggestion other than that?

unlocking on iphone 2G is done by using bootneuter.
If you are using custom firmware then you must select unlocking and the same if you using redsnow.

Or you can search for bootneuter in cydia.
Note: bootneuter is ONLY for iphone 2G (first generation). Be careful not to interrupt while it is running. make sure power save is set to never before using it.

Ok I downloaded and started bootneuter.

Version 3.9 was already installed so I installed version 4.6.

Now my Iphone is stuck on determining current setting (after succesfull flash).

What I've to do?

Edit: also my Wifi works but in settings it shows no wi fi connected......

Ok I decided to give a try to downgrading to 1.1.4 to flash my baseband again.

I installed iTunes 7.7 in order to downgrade to 2.xx firmware.

Than I plug my phone, put it in DFU but no restore button appear and I cannot go on.
iTunes recognize my tel but if I click on left menu icon it doesn't show summary page.

What's the problem?

i had an similar problem with the restore button in itunes 7.5 / 7.7 versions.
i used itunes 8.2 to downgrade to 1.1.4

Thanks for the reply, I'm not alone

I'll try but probably I will face error 16xx.

to solve the 16xx error:

- try another (direct) usb port
- reinstall itunes (if you´re on windows use a tool like registry mechanic after
uninstall then install new
- try the recovery mode instead of dfu mode

Ok,
I tried to follow this guide to downgrade to 1.1.4:

MacCiti | iRevolution

Instead of using ziphone (last point) I updated to 3.0 with iTunes 8.2 and then jailbroke with redsnow.

When bootneuter start to work it says that my bootloaders 3.9 and 4.6 are already installed and it will only flash my baseband.

After this my iphone doesn't work (phone part).

Any suggestion?
