    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

    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

    Rooted and Band-Unlocked

    Well, I not only got my phone rooted, but it is now band-unlocked so I can use USA GSM services, such as AT&T and T-Mobile. At first, I just rooted the phone. Yet, I wanted it band-unlocked, too. So I searched and got the help I needed. Details can be viewed in this discussion: Band Unlocking on D2G Sys 4.5.629 with Android 2.3.4 ? - Droid 2 / R2D2 / Milestone 2 / Droid 2 Global - RootzWiki

    I flashed the ROM back to Froyo, using RSDLite, then used BEH's Recovery & Root CD. After that, I installed Droid 2 Bootstrapper, and used that to install TBH's Unlock.zip. Thoroughly read the referenced links in the discussion thread link above. The information is invaluably helpful.

    NOTE: If you want to do this whole procedure and band-unlock your D2G, you must first SIM-unlock it by getting an unlock code from Motorola, Verizon, or a third party source (there are many on the internet).

    If the photos are on your SD card then all you need is a card reader and any of the free SD Card recovery programs. Recuva from here should work just fine: 6 Data Recovery Tools for SD Cards, USB Drives and More | PCWorld
