    Hello,

    I followed your instructions all the way through but I ran into a problem at step 9 entering the password in Cygwin.
    I tried 'alpine' 3 times with the following result:

    $ ssh root@localhost -p 22
    root@localhost's password:
    Permission denied, please try again.
    root@localhost's password:
    Permission denied, please try again.
    root@localhost's password:
    Permission denied (publickey,password,keyboard-interactive)

    I didn't know what I might have done wrong, then I noticed I didn't have the cmd-window open anymore. I opened one and re-did step 7 & 8. Now, if I try step 9 again I get the following warning message:

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ Warning: Remote Host Identification has changed! @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    It is possible that someone is doing something nasty!
    Someone could be eavesdropping on you right now (man-in-the-middle attack)!
    It is also possible that a host key has just been changed.
    etc.

    What exactly am I supposed to do now?

    Thanks for your help in advance,
    Nubs

    The SSH client that gets installed is based on the IPSW file you used. I missed that step and could not log in. Make sure you use an IPSW custom file 4.2.1 ipsw created by PwnageTool or Sn0wbreeze...

    I had the same problem and put back my phone in DFU mode and ran theteredboot again with a Sn0wbreeze ipsw... and it worked...

    It worked. I transfered the file from the wrong ISPW file that was not pwned...

    Note: If you do not want to used Cygwin. Use putty to connect to 127.0.0.1 and mount the file system. I then used WinSCP to connect to 127.0.0.1 to transfer the files. Make sure you do not save the password in your connection because you will get a connection refused. WinSCP need to connect and get the SSH key before it sends a password...

    Is there a way to check what caused the constant reboot of the unit to fix the problem ? It's great that I could recover the files but would be better if I could prevent the faulty program or mobile substrate addon to load and recover my phone!

    Thanks for the great tutorial!

    Please, I need help!
    I can't get the file named "038-0049-002.dmg.ssh" because of a problem with Ramdisk Builder.exe:
    When I type the key and the IV values in the program, they are both valid, but the program crashes if I launch the process with a restore ramdisk from a powned .ipsw file (created by snowbreeze);
    Instead, if I launch the process with a restore ramdisk from an original .ipsw file, the program is only able to create a file named "038-0049-002.dmg.dec", but no trace of the file I need ("038-0049-002.dmg.ssh").
    What I have to do in order to get the file I need?
    Thank you so much for the help!

    Thanks for this very helpful tutorial.

    I have proceed until the final step where I try to mount /usr filesystem using fsck_hfs /dev/disk0s2s1

    However, fsck_hfs complains about an "Invalid index key" and tries to fix it but it cannot. Here is the output (it fails after 3 attempts):
    Code:
    -sh-4.0# fsck_hfs  /dev/disk0s2s1
    ** /dev/rdisk0s2s1

    Is this possible on a 3G phone yet? With iOs 4.2.1? When I do the iRecovery one, I get "error receiving status!"

    2. this time extracted 4 files from custom IOS 4.2.1.
    and uploaded ibss from IOS 4.2.1 while rest of the files remained from IOS 5.0.1.
    this time the itunnel uploaded teh 3 fiiles successfully....
    but when i tried itunnel --iport 22 --lport 2222

    The files should be zero in size. I think there's supposed to be more than rdisk0 though.
