Unlock iPhone 3.1.3 Baseband 05.11.07 with BlackSn0w

Unlock iPhone 3.1.3 Baseband 05.11.07 with BlackSn0w

If you’ve updated your iPhone to OS 3.1.3 using custom firmware created with PwnageTool or Sn0wbreeze, you would probably know that even after preserving Baseband at 05.11.07 it’s not unlockable with BlackSn0w. BlackSn0w which is meant to unlock iPhone Baseband 05.11.07 (true for OS 3.1.2) but it cannot unlock iPhone 3GS and 3G on baseband 05.11.07 of when you’re running iPhone OS 3.1.3.

Update: UltraSn0w 0.93 is Out Now! It can unlock all basebands for iPhone 3GS and 3G. (Check the Updates at the bottom)

BlackSn0w is unable to unlock baseband 05.11.07 on firmware 3.1.3 because it locates a function to patch by searching the binary for reference to string “SIM is not supported” but in iPhone OS 3.1.3, the same function now uses the string “Verified”. Since the location to patch is determined by instruction search&replace, the patch itself still works in 3.1.3 after changing the string and its length in Blacksn0w binary.

To unlock iPhone 3GS and 3G running iPhone OS 3.1.3 Baseband 05.11.07 with BlackSn0w, simply follow the step by step instructions listed below.

Update:
This patch is now available in Cydia as BlackSn0w RC2 to unlock iPhone 3.1.3 Baseband 05.11.07:

do you have any idea how to get rid of emergency slide because i am stuck in the emergency slide (in home screen usb connected with itunes and there is lock sign above it) it happens after i restore my iphone with itunes. my iphone is 3gs with 3.1.3(7E18) with baseband 05.12.01.

iPhoneHeat March 22, 2010, 3:59 pm

Use f0recast to knoiw your device and the jailbreak tool.. and then use that tool to jailbreak it

Rohit March 22, 2010, 9:47 am

I tried the following steps and compleetd sucessfully without any freeze , but in my Iphone 3G there is no change and it still remains locked . BTW post says baseband 05.11.07 , does 3.1.3 have baseband 05.11.07 ? . Mine is 3.1.3 and baseband 05.12.01

iPhoneHeat March 22, 2010, 4:02 pm

baseband remains preserved if you update to 3.1.3 using a custom firmware.. that’s the best way to go for latest firmware if you depend on unlock..
now that you update directly using official firmware, your baseband is also updated to 05.12.01 which is NOT unlockable ATM. Sorry..

CGA March 22, 2010, 10:03 am

@vesh

you have to (h)activate your iphone first which ever method you use is up to you

vesh March 23, 2010, 8:20 am

smith's report March 27, 2010, 9:57 am

Major Problem.

Before reading this post I followed steps on iclarified to JB 3.13. I did so. Everything is working great until I follow the unlock steps on another site.

it says go to Cydia and add the source for Blacksn0w. Then install blacksn0w and it will be unlocked.

Now my phone is attempting to load but keeps rebooting after 1 minute or so with the boot logo. Can anyone help? Thanks.

smith's report March 27, 2010, 10:02 am

Nevermind. Google found me the answer. Thanks though.

I JAILBREAKED MY IPHONE 3G 2.2 with baseband 2.28 to OS 3.1.3 using snowbreeze. after this i tried to unlock it with blacksnow. after blacksnow was installed using cydia and rebooted, the iphone won’t start. it only shows the snowbreeze icon and nothing happens. i’ve tried the hard reset or boot thing using the power and home buttons combination but still not working. can some please help me???

iPhoneHeat April 26, 2010, 9:13 pm

you’re @ older baseband which BlackSn0w doesn’t support..
try YellowSn0w the older unlock solution..

quanpoko August 18, 2010, 11:22 am

Hi I have got the same problem using snowbreeze to upgrade my iphone to firmware 3.1.3 but with my baseband 2.28. Now, i cannot find a way to unlock it. I used ultrasn0w, blacksn0w…I heard yellowsn0w gonna work. But I cannot find the current source of it. I tried apt9.yellowsn0w.com and apt9.iha…something. but neither one worked…
Can anybody help??? thanks a lot

You need YellowSn0w to unlock baseband 2.28..
UltraSn0w unlocks baseband 04.26.08 which came with iPhone OS 3.0 stock

EMENEMS June 21, 2010, 8:36 pm

Thnxx for your co-operation, i really appreciate.
