Tetheredboot does not work with iPhone 4 Verizon about iphone-dataprotection HOT 5 CLOSED

I committed a fix in the repository, can you test it and report 
success/failures ? thanks

Thanks for the quick fix. The initial issue seems to be fixed but now I'm 
running into a new issue :

As you can see, it fails to upload the ramdisk then exits. Any suggestions? 

Thanks

OS: OSX 10.6.7

Forgot to mention, I made a new ramdisk manually doing the following :
Note: I used the following IPSW/Ramdisk
IPSW="iPhone3,3_4.2.7_8E303_Restore.ipsw"
RAMDISK="038-0974-004.dmg"

1. img3fs /tmp/img3 038-0974-004.dmg -iv 8d612fbab555c8e8f548898b0e6d3cb0 -key 
9ca594fef56655a7ad4dc1312dc4a499851d832c2eeb86f5a9ebfabe08ccedb6
2. hdiutil attach /tmp/img3/DATA.dmg
3. rm -rf /Volumes/ramdisk/usr/local/standalone/firmware/*
4. tar -C /Volumes/ramdisk/ -xP <  ssh.tar.gz
5. cp ramdisk_tools/restored_external /Volumes/ramdisk/usr/local/bin
6. cp ramdisk_tools/bruteforce ramdisk_tools/data_partition 
ramdisk_tools/dump_data_partition.sh /Volumes/ramdisk/var/root
7. hdiutil eject /Volumes/ramdisk
8. umount /tmp/img3

If I use the build_ramdisk.sh script, img3fs fails with the following error:

TAG: TYPE OFFSET 14 data_length:4
TAG: DATA OFFSET 34 data_length:ed5000
TAG: SEPO OFFSET ed5040 data_length:4
TAG: KBAG OFFSET ed505c data_length:38
Wrong length for key parameter, got 0, aesType is 100

Got everything working=) Recompiled tetheredboot on windows using MinGW and was 
able to ssh into device without issue. The upload issue was probably caused by 
using OSX in a VM :/

Thanks again

Great ! yes using a VM will sometimes create issues with usb. Btw, the ramdisk 
should work even if the ipsw used for building does not match the device (as 
long as it is for an armv7 device).
