    A simpler method is available now.

    I put together a CD to a simpler method, doesn't require bricking the phone and multiple flashes. It is the method MissionImprobable referenced, but packaged for the D2G, and shouldn't require a Data wipe, (though there is always the possibility of mishap)
    None of tools are mine, I just repackaged them to be more user friendly.
    They are at

    Droid 2 running A955 lockdown software

    I am dump when it comes to this rooting stuff. I have never done it. I have a droid 2 running 4.5.621.A955. I have some questions.

    First, where do i download all these tools like motorola drivers and RSDlite? Do i put them on my phone or my PC?
    Second, Where do i get this RootDroid2file? Where do i put it?
    Third, Where do i enter this adb comman?
    Fourth, If i am lucky enough to figure this thing out(which i doubt) what next? What version of software will be on my droid 2 now?

    I know nothing about ROM's and all that. Will i be able to still use my phone like normal once i have finished this process? Please help. I need somebody willing to walk me through this process literally STEP BY STEP!!!!!

    Thanks.

    Current Phone Model:
    Droid 4 (XT894)
    for basic SBF and RSD lite info read The DROID Wiki
    use pc, links are baked in text just click on name of file
    moto drivers USB and PC Charging Drivers - Motorola Mobility, Inc. USA
    abd in command prompt start/search cmd.exe

    easier to use iso img, don't need rsd, drivers or adb

    slitaz boot img, like ezSBF
    Droid2_D2G_DX_DX2-RootCD-2012.iso

    has options for D2, D2G, DX, and DX2
    burn to cd with imgburn, or for flash drive UNetBootin for Windows
    restart pc boot to drive you mounted img to, cd drive or usb drive
    some PCs will auto boot to slitaz, some you need to press F8 or esc and select drive
    just follow on screen instructions


    same version, rooting alone doesn't change that, rooting just gives you access to change system files/settings

    edit: added links

    links are baked in text just click on name of file

    Ok this is what i mean. I don't know how to download these files. To use this iso img thing do i have to download the unbooting for windows before i download the file to my flash drive? Plus, once i have done that you say to reboot my pc ok i can do that but what do you mean by i might have to hit f8 or esc to find the file? It will be on my flash drive can i not access it from there?

    Also, if i manage to get this right, how do i flash back to an eairler software version? What would that version be and where do i go to find it?

    yes you need that to correctly place image on flash drive
    iso boots pc to linux system, it's a live image meaning, no changes are made to pc, remove cd or flash disk and pc reboots normally
    once on 4.5.621 you can never go back to earlier versions

    edit: not all PCs support booting from flash drive, most newer PCs do

    Oh!!! I thought that was the purpose of rooting?? So even if i root the phone i can't replace 4.5.621 with anything else? I have certain apps that do not operate properly with this software version. Is there a chance i can find a droid 2 that has not been updated yet that i can root to avoid further updating?

    the purpose of rooting is to changing system files
    most people flash a custom rom like cm7

    what apps, are not working, most likely, someone has found a work around
    or they just work on cm7
    a change in the locked bootloader, is what is keeping, phone from being compatible with earlier system versions
    that can not be undone

    edit: flashing a rom doesn't change base system version, because of the locked bootloader

    you can find used D2s, on ebay, just ask seller what version is on phone

    You will need DROID 2 bootstrap, in order to access custom recovery
