iOS7 bruteforce support?

[GoogleCodeExporter]

Hello,

I have a iPhone 4 with iOS7 beta 3 installed.

I did the jailbreak using redsnow and boot up  with the patched iOS5 firmware 
so I can do the bruteforce.

I am able to access the device, copy everything over to my laptop.

However the bruteforce does not work.

I get stuck on the 

passcodeKeyboardComplexity : {'rangeMinimum': 0, 'value': 0, 'rangeMaximum': 2}
Trying all 4-digits passcodes...

and nothing happne.

On the iPhone log I can see
booted from secure root: give device keybag access to everyone
IOConnectCallMethod on AppleKeyStore selector 6 returned e00002c9
IOConnectCallMethod on AppleKeyStore selector 5 returned e00002bc

this patch should help, you'll need to rebuild the ramdisk.

The patch works :) Thanks so much,

I am able to bruteforce and recover the pin.

However the keychain-2.db seems empty now.

So when I try to decrypt it I get the following error

python python_scripts/keychain_tool.py -d 
edaa4fbd219282feed0d0a2e52514af65fbdd565/keychain-2.db

Should I create a new issue for that problem  as different ?

the error you have is caused by the sqlite WAL format, where the database is 
stored in 3 files instead of one. after that there is another error, the 
keychain format changed, the encrypted data is now encoded in ASN1 instead of 
binary plist. 
i created issue 115 to keep track of this, i currently cannot work on it but it 
will eventually be fixed.

@fridaythirteen77 use the ios 5 ipsw, even if the device runs ios 7.0.4.
http://appldnld.apple.com/iPhone4/041-8358.20111012.FFc34/iPhone3,1_5.0_9A334_Re
store.ipsw
also for the python error you need pycrypto
sudo ARCHFLAGS='-arch i386 -arch x86_64' easy_install pycrypto
(see https://code.google.com/p/iphone-dataprotection/wiki/README)
