Thanks Screamankit for your reply.

Just to be sure I understand correctly, I have an AT&T (purchased directly from them) so I'll use an UNACTIVATED firmware?

I tried it but got an error message.

Hi guys,

I've just upgraded using the method from a jb 3.0 but i've lost all of the apps/**********/ etc that I had downloaded before. Is there a way to get them back!?

I did back it up as all my messages/contacts are up to date

cheers

I just did the upgrade and everything went fine except one thing. I have no cell service now. It doesn't even know my phone number. When I go into settings and then phone, my number shows as "Unknown"

Did it erase my SIM card?

EDIT: Nevermind. I got it working. I just didn't do the unlock. Didn't think it was necessary. I ran ultrasn0w and now everything is copacetic. Thanks for the great tutorial!

that isn't so bad becouse i can use my app,ipod and so...and use other phone for calls...but if u know some safe way to unlock it completly let me know...anyway thank you a loooot for responds..i am very grateful

ur welcome karabaja... now since ur able to access phone features did you check your baseband cause if its 4.x.x you can install ultrasn0w and get it unlocked and if its 5.x.x you can even try to downgrade the baseband by using fuzzyband ie if you have bootloader 5.8 or lower which will allow you to unlock.

Did you get the 16xx error.

solution:-

1.make sure you are not doing the CFW restore with the iphone in DFU mode coz that will trigger these errors.try doing it with your phone in normal working condition.I would recommend you to do it without any sim card inserted.Try using your main usb port which is usually at the back to avoid these errors.

If the above step does not work then try the second option.

2.if you want you can even try the ACTIVATED one as is wont affect you in any ways.

[karabaja]

yes,i can access,and i checked it...and i have 5.9 bootloader so fuzzyband cannot access it
so i'll have to wait for some1 to unlock it?
btw my friend downgraded it to 3.1

Dont worry stannie65 itunes dint restore your jailbroken apps from the backup as your appsync modification got deleted from cydia with the jailbreak.

steps-
1.install appsync 3.1
2.on the right hand side in itunes right click on your iphone and select restore from backup.
3.select the backup copy that you had made before the jailbreak.
4.your apps will get synced with itunes just like old times.

@karabaja

sorry to hear that karabaja but dont worry cheer up as the devteam is free now after the 3.1.2 jailbreak and they have started to focus on unlocking the new 5.x.x baseband...so its just a temporary problem...use your iphone thinking its an iTouch

lemme know if you want any help in the future.

this means you downloaded a custom firmware 3.1.2 which was not ACTIVATED... now the only way to activate the phone is by inserting the official sim card with which your iphone was purchased ie AT&T or Rogers.
After inserting the official sim your iphone will be registered within a few seconds after that you will be able to access your iphone features so go to cydia install ultrasn0w and then it will get unlocked.

Tried an activated FW. I still get the 1604 error.

SCREAMANKIT I so hope that you can help me. I'm having a similar issue. I downloaded and installed the nonActivated 3.1.2 firmware and installed it on my 2g. I have a 3GS AT&T account with a fully activated 3G sim and my thoughts were I could swap the genuine ATT sim between the two phones. Well the 2g is stuck at the slide for emergency screen, but my carrier has a full set of bars and showing AT&T. When I connect to itunes of course it wants to activate an already activated sim on a non activated iphone and promps me to set up a regular iphone data plan as oppose to the 3G plan. So I've tried using ireb to allow me to install the ACTIVATED 3.1.2 firmware on my 2G without any luck. I continue to get the 1601 error and itunes continues to pop up and check the iphone. Any help with freeing my 2G would be greatly appreciated. I'm holding off on installing the custume 3.1.2 on my 3GS untill I can get things working smoothly on the 2G.

Thank you,

The 2G phone is a previously JB and Unlocked using RedSnow on 3.1. And when trying to restore to the activated FW itunes gets stuck at "preparing the iphone for restore scree..." and then I get the 1601 error. NOw the phone is stuck on the black screen without powering on of kicking out of DFU mode. I still think I'm confused on the difference bw DFU and recovery mode, it seems to be used so interchangeable among all the sites and post.

UPDATE...

got my hands on iReb 3.1.2....allowed me to do a restore. I really did want to keep the push notification feature, but I suppose I can live without it as long as the phone works...thanks to those that made the custome FW.


SAME QUESTION AS POSTED BELOW. I'M PRETTY SURE FOR MY 3GS WITH AT&T CONTRACT I JUST USE THE UNACTIVATED CUSTOM FW. MY QUESTION IS WILL IT AUTO-ACTIVATE OR DO HAVE TO GO THE THE ITUNES PROCESS AND SPECIFY MY DATA PLAN ALL OVER AGAIN.

[gadjet0]

Can someone confirm before I do the wrong thing.
I have a contract Iphone 3G with 3.0 on O2 unlocked with ultrasnow.

I think I should download unactivated custom firmware 3.1.2, Shift restore from Itunes and then use ultrasnow agaqin to unlock.

Does that sound right?

Thanks for any help.

[SuperrSkillz]

im trying to jailbreak my iphone 3g on 3.1.2
i downloaded the 3.1.2 custome firmware,
i put it in the correct folder.
i restarted i tunes but it didnt ask to be updated
but i thought well maybe it didnt ask because it already is on 3.1.2
so then i left shift and clicked restore
selected the custom firmware and it said preparring for restore
but on my iphone it shows the picture to connect to itunes

was i supposed to enter my iphone into DFU mode?
or what did i do wrong?
please help
thanks

hi screamankit!
seems like a lot of people have been getting a lot of help/advice from you. cheers to that!

my question is this: what's the worst thing that can happen should i fail to follow the steps you've laid out?
i have a 3 gs with 3.1(7c144). i'm almost certain that i'll fcuk up a couple of times before i get what i want and i'm afraid i might render my phone useless.

thanks in advance!

[Halo_2]

i try load the custom firmware but getting error 1600
