    Trying to recover data off my Iphone 3GS to MAC VM and I tried using this guide, however, I um unable to run DD as I cannot get the filesystem to unmount or mount as read only and I keep getting 'Resourse Busy' error. Please see my logs here:

    localhost:~ root# df -kh

    I downloaded umount from somewhere and scp'd it to Iphone:

    MacAdmin$ scp ~/Desktop/Iphone\ FW/umount [email protected]:/sbin/
    [email protected]'s password:
    umount 100% 15KB 14.6KB/s 00:00

    localhost:~ root# umount -f /private/var
    Killed
    localhost:~ root# mount -o ro /private/var
    mount_hfs: Resource busy

    Sorry - wrong post

    I'm not sure why people claim the bs=1M option will fix your problem -- that has nothing to do with what you're experiencing.

    The device is /dev/rdisk0, not /dev/disk0.

    Default Linux
    Any idea how to do this on Linux?

    So far my img is being created just fine.

    I don't have access to a Mac, but I have Ubuntu Linux access.

    @atomic hooligan
    First of all I'd like to point out that you rock! you're the man! your tutorial is the most professional tutorial on the web.
    So, thank you very much!

    @saintx7
    'setgid : invalid argument' error means that you haven't configured your mkgroup on the ssh server side (unix? mac? win?). If the groups haven't been created on the server side, the client connection will fail after authenticating successfully, with the error message: setgid: Invalid argument.
    Cygwin(Windows)/Unix ssh server - Run the command mkgroup -l > /etc/group
    Then it should work.

    @jasonchb
    There are some topics found on the web, but I believe that in order to save time, just do it the other way around... from MobileTerminal on the iPhone ssh into your computer.

    For All Windows Users
    The following method worked for me like a charm!
    I have a 3G iPhone with 3.1.3 installed, and I wanted to retrieve files from before I updated the iPhone.

    I installed cygwin with openssh and ddrecover packages on my Windows XP:
    - Download and install setup.exe from Cygwin Installation
    - Select the openssh and ddrecover packages in the installation (you can use the search box to find them).
    - Run cygwin and enter the following commands:
    Code:
    mkgroup -l > /etc/mkgroup
    mkpasswd -l > /etc/passwd
    ssh-host-config -y
    net start sshd
    - Keep cygwin open.
    - After performing the steps to jailbreak the iPhone and install openssh and MobileTerminal enter the following command on the iPhone as root (use 'su' command to login as root):
    Code:
    dd if=/dev/disk0 | ssh <yourXPusername>@<yourXPIPaddress> 'dd of=iPhone-dump.img'
    - You will not see any progress bar, but you can check the file size on the PC as it grows. It took me 9 hours to transfer my 16GB image file.
    - The file will be located in cygwin's installation folder under home/<yourXPusername>/
    - Mount the file with:
    1. OSFmount - Free
    2. MountImage - Trial
    - Use PhotoRec or other software to recover files from the mounted image.
    - For PhotoRec - choose Apple partition map as the partition table format. You can also choose the file types to search.

    Good Luck! :-)

    Default Recovering deleted texts and other info on iphones
    I am a licensed private investigator and I can recover deleted text messages, call logs, photos, video and other deleted information off of an iphone. You can either send the phone to my lab or you can purchase a kit that allows you to do it at home. For a free consultation ask for Tom 8 6 6 6 4 0 1 0 1 0.

    Any news for iphone4?
    I need help for my photo and video

    Hi your explaination for doing this with a PC is great, I had jailbroken my iphone 4 and everytime I try to run Cydia(or Safari) it opens quick and closes? Also when I installed on my PC (Windowas 7)cygwin and installed openssh and ddrecover, then try and run the commands it keeps telling me to go to the help, so I enter the code for the help menu and also has errors?

    Please help.

    Thanks,

    Ok i read this but i'm still not sure. So i voice recorded this one funny thing my friends and I did. Well it was 16 minutes long. I wanted to trim it so i did like right where the funny part was. And like before i did the trim before so I knew it will divide them into 2 different voice memos but instead it got rid of the part that i wanted. SO i was soooo upset.

    DO you know how i could get the other part of the memo back?? (the voice memo that i want not the one i don't want)
    Please help... Thanks!

    Unhappy help
    so after i write the "dd iif=/dev/disk0|ssh ((username)@ipaddress) dd of=iphone-dump.img" i put in my password then says " 0 bytes transferred in 0.020694 secs (0 bytes/sec)" i can see the "iPhone-dump.img" file on my computer but it too says zero bytes. why is this doing that?

    Default iNewb!
    Hi, I know I am late but it happened to me a year ago and I have been searching for a long time. I believe your guide is very helpful, with the outstanding replies from other users. I on the other hand am not able to have a chance at trying to resolve my issue in relation to this thread and similar to everyone's problem. As I am reading all the of replies and comments, I am happy that everyone is involved and helpful.

    *Cutting to the Chase*

    I have an iPhone 3GS OS 4.0.1 and a Windows 7 computer. I completely do not understand how to utilize this guide in my favor as it is too complex from my understanding. I have Terminal on my iPhone 3GS and I tried installing OpenSSH through Cydia and it will not let me as I am getting the following message, "Wasn't able to locate file for the com.dba-tech.common package. This might mean you need to manually fix this package." I really don't understand what that means. It will not even let me remove and reinstall. As for my computer I installed Cygwin but I do not understand how to use it. I do indeed have important information on my iPhone that some files, photos, and voice recordings were accidentally deleted and not backed up that I am trying to retrieve.

    I know I am a newb but I do really need help with this and understanding it and explained to me in Layman's Term. If someone or anyone can give me detailed step by step instructions, that would be wondrous. Thank you in advance.

    Help, I used wondershare dr phone to try to recover deleted files and it gets to 99% and didn't want to finish. I'm on a jailbroken iphone 5 on 6.1.2 and accidentally deleted 20 photos/vids yesterday and they aren't in my backup.

    I tried EaseUS MobiSaver 3.1 and it finished but doesn't show any deleted pictures. I shows all the photos from the last 3 months, but when you click "show deleted" it doesn't have any.

    What's I'm wondering is, if I try the photorec, would this work better? or if EaseUS doesn't see them, nothing will?

    I know this is a older post but does anyone know how to do this through USB? I can do it with cygwin on a android phone and I can connect to the phone usb with putty so why cant I pull this phone image through the USB port instead of it taking hours to pull over wifi? There has to be a way. Anyone?
