    Here is the story. I had an app to organize photos but it was making my phone misbehave so i uninstalled it. I went into my files and deleted the file for that app considering i wasn't going to get it again but as i deleted the file i noticed it was taking too long to delete and then the next day when i was looking for a photo i seen my photos where wiped out (completely gone) until i seen app that claim to get them back but they all say my phone needs to be rooted.

    re's
    Just attempted (3 times) to use the link on page 1 of this thread after burning it as in iso to a cd...
    First off after the pc reboots on the cd it checks the pc's system and asks what sound card I want to configure... no biggie I just hit enter, it then checks and see's the phone runs the start up script asks which phone... I select option 1 (droid 2/r2r2)... it mounts (I guess) and has me go to bootloader... it then "erases data" and I wait and wait as it installs... after about 10 minutes of watching the percentage count up it says it will reboot the phone then continue with the rooting process... the phone reboots... but the program just sits there smiling at me as if it is still waiting for the phone to do something.
    I've attempted to rebot the phone a couple of times thinking the program "just didn't see the phone rebooting" or something but nothing ever happens... I finally use the ctrl-alt-del to get the pc out of just sitting there (after removing the cd)... I am using windows 7 but that shouldn't really matter since it's booting off the cd anyway.

    you know there is three different iso files in op
    sound like you downloaded the Droid2_D2G_DX_DX2-RootCD-2012.iso yes?
    to android os (it booted normally), or back to bootloader?
    program sticks, try toggling usb debugging
    or reboot phone manually

    Actually your correct... I did d/l the global version this time... BUT what I had been using (to my credit) orginally was the correct version 213megs big I believe).. when using that version it would boot off the cd as before... asking the sound card question but doesn't ask which phone I have... I believe the options were flash sbf, root phone, or shutdown... those 3 options.
    The program would run, have me go to bootloader, erase/install (the waiting percentage thingy)... reboot the phone (twice) have me go and wipe cache, restart phone and still no root.
    At the end of the rooting process it does show errors that I files can't be re-written or are hidden... I don't know how to do a screenshot while outside of windows runningI take it that this program(cd) could be run windowed so I can do the screenshots to sow the errors...?

    the Droid2_D2G_DX_DX2-RootCD-2012.iso is a muti device root program, just choose your device it works fine
    still no super user app?
    you may have to use the SBF option first

    your checking usb debugging (settings/apps/development)
    and selecting charge only usb mode?

    also have you used MD5 & SHA-1 Checksum Utility: verify the hash checksum to ensure the file integrity is correct with the matching file
    I added md5 hashs to op

    This is the iso that just hangs after the phone reboots and doesn't do anything after the phone reboots the first time.

    I have the su app from a prior rooting (before the last update ota from verzion... running it shows busybox, ES File Explorer, Superuser, and Titanium Backup
    running Titanium Backup gives an error that rooting is needed to work and a red fail for being a rooted device.

    usb debugging is selected as in for the phone not to go to sleep... I attempted both a charge only and as per the instructions in PC mode... if I remember... in pc mode the program acted the same as when I used the multi device program and never seen the device after it rebooted (but I may be mistaken since I've attempted this a couple dozen times now).


    I have not tried this... since I really don't know where to locate/determine where to find hash sizes at.

    just because titanium doesn't work, doesn't mean your not rooted
    try updating superuser binaries
    open superuser/settings preferences/ general/Su binary tap to update
    it will say current version already installed click updated anyways
    or it will say new version available click update
    if supersuser can update you are rooted

    or check superuser log and allow titanium, , sometimes the popup doesn't work right first time, and times out
