I'm trying to use your walkthrough guide but I encountered few issues.
I have an iPhone 4 using iOS 4.3.3 firmware but I am using iOS 4.2.1 Restore Ramdisk (038-0032-002.dmg) file ('cause RamdiskRebuilder doesn't work with iOS 4.3.3 Restore Ramdisk file).
I have to use 6a and 6b. But 6b stops at : "[INFO] Kernelcache kernelcache.release.n90 loaded".
I have to "terminate" it with CTRL+C and then launch the "itunnel_mux --lport 22" command.
Then using Cygwin I try to ssh the device and mount the filesystems but I can't see anything. When typing "ls", the command is not found???
I don't just get it! What is wrong?
Thanks in advance if you could answer me.

Looks like you're in . If you can't mount the filesystem most commands will be unavailable.
I would fix the Ctrl-C issue. Indicates something isn't working right. Anything after that point is suspect.
Note: If tetheredboot (step 6) works, steps 6a and 6b are not used.
Note2: If tetheredboot fails, power off the phone and start over.

Thank you very much Mes for your reply.
Ok! I have to explain myself a bit more. When I use tetheredboot (step 6) only, everything works fine but the device's screen stays white and doesn't show the "snowbreeze apple" and I hear the noise of the device pluging out...
Otherwise when using steps 6a and 6b I managed to have the "snowbreeze apple" but step 6b hangs at the end so I have to "terminate" it with CTRL+C. Then I can start an SSH session "normally".
I keep on trying to use step 6 only (by powering off the device and starting over and over) but in the end I only get the white screen and I am not able to start an SSH session.
So I'll try to stick with the 6a and 6b steps but I think you're right I am not able to mount the filesystems...
I was thinking about something else... is it a problem that I use an iPhone 4 with iOS 4.3.3 and trying to ssh with the Ramdisk of iOS 4.2.1?
I read on other different topics that with xpwntool under Win 7 it is possible to decrypt the Restore Ramdisk put-in the content of the ssh.tar archive and rebuild the Ramdisk.
But I didn't find where to download a xpwntool version which works under Win 7 and I don't know how to decrypt/rebuild the Ramdisk with these tools.
Ok! Thanks again Mes for your reply.
I'll try to figure out a bit by myself but I am not confident in any progress.
And if anyone could explain me different things about xpwntool (or have a link to another topic) under Win 7 I would be really grateful.

Once ssh is working, all ssh connection options should work.

Thanks again Mes for your reply!
I've got news! Really good news : IT'S WORKING!!! somehow...
Actually I am using the ssh program Tunnelier which has a terminal interface and an Explorer GUI. So it is really userfriendly for those who are struggling with Cygwin.
At first sight mounting filesystems wasn't working but... all I had to do was refreshing the explorer in the mnt2 folder "et voilą !" everything showed up.
So thank you very much Mes for everything (I am saving all my data, photos, calendar, address book, text messages... right now) it's a relief that I can have access to these files.
And good luck to those who are struggling recovering their precious data.

So I downloaded the software, created a custom ipsw and extracted the required files.
Unfortunately when trying to create the SSH build with 018-6051-014.dmg the app "RamdiskBuilder" crashes.

This is strange: it should work with whatever version under iOS 4.3...
Ok! I'll give it a shot.
Otherwise you can try to unpack - copy ssh.tar - repack the dmg file with xpwntool.
If you need a walktrough I can write it for you!
I downloaded the ipsw for 3GS jailbroke it extracted the dmg file but no luck RamdiskRebuilder crashes.

I'm runngin Win7 x64 but that shouldn't be the problem as I was able to create the v4.1 SSH without any issues.
Any help would be appreciated.
A side note, I noticed that inside the ipsw the kernelcache.release.n88 file wasn't available but there was a kernelcache.release.s5l8920x.

Ok I made it! I downloaded a custom firmware (from a 2shared site, if you need a link MP me) for iPhone 3GS iOS 3.1.2 and RamdiskRebuilder worked flawlessly. So I've got the 018-6051-014.dmg.ssh file.
Since I don't own an iPhone 3GS but only an iPhone 4, I can't go further to help you.

A ramdisk should be built for each version. Sharing may be possible between minor versions (4.0, 4.0.1) but it's risky. Be safe, create a ramdisk.

Right click on the 'directory' that contains tetheredboot and select "open command window here"
.... or ....
Start/Run/cmd .... and change directory to the tetheredboot directory
@krod13. Good, a power button. Note: This thread is for experienced users.

No problem. Good luck

Mes, the tetherboot.exe and other programs are on my usb(D). Can it still be done?

No problem as long as 'everything' is in the same directory.
