    I've been reading around in the forums here for a few weeks now and finally decided to join. I have a A955 D2 and been wanting to upgrade it. I've been wanting to try CM7 but I can't figure out the SBF (system boot file). I don't want to brick it but I can't seem to find any real guides on how to perform a SBF flash or when you need to do a Full or partial SBF flash? I know a SBF can brick your device if you put a new on over a old sbf? or something like that? Not sure I have a hard time understanding it.
    I've also been looking for info about using these other roms on other networks then just Verizon? For instance I want to have my phone flashed over to prepaid Cricket or something else of that sort. Will I still be able to use my phone with them? I don't have my phone on Verizon atm I'm using it on another local prepaid carrier with unlimited phone, text, +2.5GB data for $35. Its considerably cheaper then Verizon's plan for me at least. "Please excuse my improper formatting and grammar."

    Phone Info:
    A955 D2
    Sys ver. Verizon.2.3.20.A955.Verizon.en.US
    Android Ver. 2.2 (Froyo)
    Kernal: 2.6.32.9



    Thanks in advance for any replies!

    P.S. Any reference guides for some of the terminology would be great if someone has a link to a threat I'm able to Google most of it but lots of it leads me back to these forums w/o much a definitive answer.

    You don't need to sbf to load cm7. You need to root the phone, get rom manager premium from market and you load cm7 nightlies from there. Do some research on this before diving in. There are other ways to do this too. I find this to be the easiest for beginners. PM me if you need help

    You'll need:

    Latest CM7 nightly: http://www.revnumbers.info/
    Z
    4Root (Market)
    Droid2 Bootstrapper (Market, I think, but if not google for the download)

    Download latest nightly to your SD card.
    Install Z4Root and root phone.
    Install Droid2 Bootstrapper and install and launch Clockwork Recovery.
    Wipe data/cache
    Wipe Dalvik cache (Under Advanced menu in Recovery)
    Wipe Battery Stats (Under Advanced menu in Recovery)
    Select Install zip from SD card.
    Browse to CM7 zip and select it.
    Reboot, activate phone if necessary, allow apps to restore, set up email accounts, etc.
    Install ROM Manager - use ROM Manager to launch Clockwork Recovery once you have CM7 installed.
    Uninstall Droid2 Bootstrapper - not compatible w/CM7.
    Calibrate battery using Battery Calibration app from market (do this any time you move to a new ROM)

    You're using the Install ZIP from SD card option, right?

    Try the toggle signature verification option and then try to install it again.

    same error though it gets farther. I'm going to try downloading the 2011-8-08 release its the last one with a noted change on the change log.


    Thanks btw for helping me troubleshoot this!

    Making sure you're in clockwork recovery - you did this, right?

    Install "Droid 2 Recovery Bootstrap".

    Run the Bootstrap app. Press the "Bootstrap Recovery" button and accept any Superuser alerts that pop up.

    Then, press the "Reboot Recovery" button.

    Then when in Clockwork recovery the menus should all be in green...

    When disabled, toggle signature verification will say: "Signature Check: Disabled"

    and the other thing to do is check the MD5 sum to make sure you have a clean download. Google MD5 check if you don't have an app to do that.

    Yup, seems the 8-15 release didn't work. I installed the 8-8 one but now my home key doesn't work. I have to spam the back button to get out of apps/menus. lol seems I can't win for loosing here almost.

    Bizarre luck you're having...try the last nightly before the one that failed assuming you haven't thrown your phone into the wall yet.

    It is my luck lol. I did run the hash check on all the first 2 I downloaded with a download manager didn't work. I disabled my accelerator and they started passing MD5 just downloaded insane slow. I'll try another install as soon as this last download finishes. 14.7KB/s Vrrooommm~ putting several zips on the SD card this time so I can make sure ones good.

    One other question the Bootstrapper app has two Clear Cache options one is Clear Cache/Factory reset and the other is Wipe Cache Partition. I did them both last time to be safe but if I can avoid the total reset Its always nice

    When moving to a new ROM the first time (e.g., CM7 to MIUI, or from stock to CM7), always wipe data/cache.

    When updating within the same ROM (CM7 nightly to next nightly), just wipe cache/Dalvik cache (Dalvik is in Advanced menu).

    If you start experiencing issues after loading a number of nightlies you might need to wipe data again at some point...but I'd wait until things start going wrong before doing that.

    Good luck...I'm downloading the most recently nightly now and it is indeed S-l-o-w....

    I just restored a CM7 nandroid and installed the 8/15 nightly w/out issue, so the most recently nightly is fine (at least it installs)..going to boot up now and see if it runs. Been on MIUI for a while, going to see what's been going on with CM7 lately.

    Oh, forgot, you should also calibrate your battery using the free Battery Calibration app from the market whenever you go to a new ROM.

    Sigh, this is getting annoying now. I can't even get 8-8 to load. Maybe its my version of Clockwork recovery, not sure though seems odd. Clockwork v2.5.0.8 and 4zroot 1.30

    MIUI another rom that can be loaded w/o a SBF flash? or with the same flash tools as CM7? I might give it a shot also. CM7 is def better then the stock verizon OS. Much faster and touch screen is more responsive so far that I've noticed.
