I ran it – and it appeared to work perfectly – however upon the device rebooting – it just sits on “searching” for the network and wont find anything

I’ve tried 2 different SIM cards which both work in other phones

Any ideas?

I searched through the internet the whole day yesterday, because I was stubid enough to update my new iphone 3G (jailbreaked an unlocked) with itunes. What happens is that the new update 3.1.2 also changes the baseband, which is so far not downgradeable anymore with most of the iphones. In principle the unlock works so that the iphone accepts the SIM card, but it will not find any network because of the baseband change. Everybody who did the same mistake like me can only use the jailbreaked iphone like a PDA/ipod and has to wait until the DEV team has some news….

If somebody has luck and an old bootloader version in his iphone, he can downgrade his baseband using the tool Cydia Fuzzyband. Just search for it in the Cydia tool and install it. It will also tell you if the baseband downgrade is possible or not, by looking at the bootloader version.

Hi All,

Simply because your IPHONE is running under 5.11 modem firmware, this cannot be unlocked at the moment the new Pwnage is for JB of FW 3.1 and above.

Lets wait for the dev team to release the unlock solution for this 5.11 Modem Firmware.

Hope this info did help.

Regards,
Mikee

3.1.2 cannot be unlocked yet. but you can jailbreak it. ultrasn0w works with lower baseband not with 5.xx.x. you guys have to wait. if it was jailbroken before you have to use pwnagetool to upgrade to 3.1.2 but if you have upgraded without pwnagetool thats it you gotta wait.

so the above instruction is a misinforming people. maybe a moron who cannot see whats going in the tech world.

Gustavo Leon Madrigal October 16, 2009 at 1:28 am -

actually, now, no one is working on the unlock of the 5.11, neither the Dev team, the chronic team, GeoHot or Snowbreeze, so we are stuck on an iphone without service
bobbyp October 17, 2009 at 12:13 am -

well Gustavo, the iphone was made for att… so you cant really blame ne one but your self
Omar October 18, 2009 at 6:50 pm -

That not work for me because I have the baseband 05.11.7 end
bootloader 05.09, I need help!!!

Hi

you can not unlock if you have upgrade with 3.1.2 before with standard Itunes upgrade. You have to use the customized firmware. If you have the 5.09 Bootloader you are a happy guy. Use a jailbraked 3.1.2 install Fuzzyband and downgrade the Baseband (just possibel with Booloader 5.09)

hey Christian………. i saw ur comments and how it is possible to downgrade 5.09 bootloader tell me then i will surely apply ur suggestions ……………….. i guess u are totally bluffing and fooling the viewers who are having problem……… do not do this kind of mistakes…………. coz there are so many people who are facing these problems …………….. do not make them fool bro………..

Diwakar,

Christian’s post is right on. I followed his instructions, downgraded my band using fuzzyband and was able to load 3.0, run redsnow, jailbreak and unlock my phone again… now working with t-mobile again.

I think most people in this forum can downgrade to a 4.x.x band using fuzzyband, def worth a try.

Hi All
I have bootloader 5.09 and fuzzyband is saying downgrading will only work with baseband bootloader 05.08 I think we all have to wait for dev team.
Jonny October 23, 2009 at 8:28 pm -

Hi,
I did update my 3G to the 3.1.2 and tried to jailbreak with blackra1n. I followed the steps and I saw the little man with the iphone. Now I get a cable with the itunes logo and it shows “No SIM card installed, Insert a valid Sim with no PIN lock to activate the phone” . So i´m stuck and i can´t even get to see the menu. I have also itunes 9 by the way. What can I do. I need help

PLZZ HEEEELP !!

Hi perlc,
Try hard reset your phone. Press Power+Home at the same time and hold until it restart.

tha supar unlock iphone good sar
mused January 16, 2010 at 2:22 am -

Do not use ultrasnow for 3GS with baseband 05.11.07. U will not be able to load network list. Run blackra1n instead. It will go to recovery mode every time u reboot. So u have to run blackra1n every time u reboot the phone. This isn’t a bug though, it’s a feature called tethered jailbreak which is enabled by upgrades Apple made to the bootrom and the fact ipt3 uses nand flash. That is the only available jailbreak for 3.1.2 baseband 05.11.07.
dante January 20, 2010 at 1:42 pm -

i encountered the same problem as well. Just unstall Ultra snow from the cydia menu and reboot the iphone and the problem will be solved…
