    Hey,
    I have a Droid 2 that I can't seem to get the OS flashed back onto it. at first it gave the 'batt Low' msg then I got a charger and then 'batt ok ok to program'
    I have tried in RsdLite and ubuntu sbf_flash to get every relevant .sbf file to work and so far have gotten nothing except back at the bootloader. I also tried loading the sbf's onto the sd card and it gives me a 'signature verification failed' here are the sbfs i have tried:

    <<VRZ_A955_2.3.20_1FF_01.sbf>> the only one that appears to flash correctly yet fails and gives a 'failed to swutch to BP passthrough mode' or similar error.

    <<SHADO_X6_2.3.13_SYSTEM-ONLY.sbf>> Fails, gives critcal error FEBE 0047

    <<DROID2_X6_2.2.20_SHADOW_BP_C_01.09.05P_P2_USERBLD_SECURE.sbf>>
    gives:
    ERR: A5,70,70,00,1F
    MEM_MAP BLANK
    SERVICE REQ'D

    any thoughts, suggestions?

    :welcome:

    I don't know much about the A955 Droid 2, but I do know that loading the .sbf files to your sdcard is pointless. And not only that, but the second two are NOT for your phone model. So to sum up, as you already should know from your post, if the .sbf file is not for your phone model and your phone model only do NOT try to use it. Unless you just want to potentially turn your phone into a paperweight.



    Sorry I had no real solution for you and good luck

    with a full battery use the sbf from here:

    TBH & MyDroidWorld Present: Droid 2 (2.3.20) Triple Threat

    and follow this video...ignore the part about the patch and just follow the steps after booting into the bootloader which is power on + physical up button.






    I know the video shows a droid x but the device is the same and the steps are the same except you will use a different file and how you get into the bootloader.

    Afterwards when it tell you to wipe you do so by powering on and hold x and hit the search button on the physical keyboard.

    When powering the device on hold the 'x' key and wait for the ! android symbol , then hit the magnifying glass search key and it will take you to the recovery console. I am droid exactly what is presented in that video but when i goto 'wipe data/factory reset' i doesn't load anything.....goes to the 'reboot system' option......and then back to the 'OK to Program' :(

    Yeah, I got them mixed up.

    This is the error message Rsdlite is giving me when I flash <VRZ_A955_2.3.20_1FF_01.sbf>.

    Can anyone make sense of this? I'm thinking at this point the unit has an issue with the logicboard that won't allow the rom to load. I would love it if someone could suggest something more.

    Did you ever get this to work? I've SBF'd about 20 times previously but I'm getting the same set of errors this time. :icon_evil: I'll check back if I get it working. Curious to know if someone else already figured it out, though.

    To sum it up:

    -SBF file is correct one from TBH
    -RSD Lite 4.8 on Windows 7 (not the issue - fails from command line with admin rights, as well)
    -flash fails immediately

    I am assuming that my board has a bad NVRAM, and the flashing doesn't stick due to this. Are you sure you have the updated drivers installed and the .ini patch? look at the error log and see what it says.

    Got mine working again this afternoon. First tried flashing bootloader sbf...that downgraded the bootloader version. Still no joy, but new errors. Then had to uninstall all moto drivers, motoconnect, motorola devices from device manager, and rsdlite. Reinstalled drivers and rsdlite and then it worked. Yay!

    Hope this helps someone else someday but my issue might have been a one-off flukey thing.

    Actually, uninstalling and reinstalling the drivers are a troubleshooting thing for RSD Lite. Normally, though, RSD Lite just won't install anything rather than erroring out. :) Glad you got it working!

    ya, i agree...I think the key for me was reflashing the older bootloader.dancedroid

    The RSD lite issue was secondary to that.

    Milestone A853 stuck in bootloader 2c.6c

    I am having simular issues.

    Wifes battery died, she turned it on went to bootloader.. i cut a usb put it on the terminals to charge.

    Phone had CM6, with CW Recovery.

    I cannot get out of the bootloader, could not get into recovery either. I used RSD to install SPRecovery, that worked fine, so i went into spr and tried to do a nandroid restore, it fails, tried to install a rom says E: no tar data er something.

    So I downloaded VZW_A855_FRG01B_QSC6085BP_C_01.43.01P_SW_UPDATE_01.sbf
    gets to 99% then Fails: Error switching phone to BP Pass through mode.

    I am downloading Droid-2.1-Flash.sbf from XDA..im going to try that.

    Please Help! My wife is blaming me cuz i rooted her phone and put CyanogenMod on it. It has been running perfectly fine since CM6.1.1 stable release.

    I couldn't get it to switch to BP Pass through mode to save my life on any Windows 7 computer. This is what I did that finally got through that:
    Windows XP 32bit
    Motorola 4.7.1 drivers
    RSD Lite 4.9
    Droid 2 SBF file

    Basically make sure you do it on a Windows XP with the proper 32 or 64-bit Motorola drivers installed, and the newest versions of software/drivers installed.
    Got through it fine... although it said passed, the phone still wouldn't make it past the bootloader for me. But, you may have better luck than me beyond that.

    I thought mine was bricked, tried everything above, nothing worked. Finally in a desparate effort booted to recovery mode, reset to factory. I lost my settings and some apps, but it wasn't a brick.

    I got force-fed Gingerbread by Verizon last weekend, It worked great most of the day (EXCEPT for wireless tether) until the battery died. As soon as I installed the spare battery, it started bootlooping on me. I researched it and it appears that I did the same things you have tried. I tried countless SBF files, all either failed or said they were successful but the bootloop continued. After about 5 hours of this, I found a blog that said there was an issue going from a rooted Froyo directly to Gingerbread OTA and suggested that the only way to recover from this was to restore the phone to factory settings, then install Gingerbread and my apps, then root the Gingerbread install. I booted to recovery mode, restored the phone to factory, let Google recover (Most of) my apps and contacts, then upgraded to Gingerbread without issue. I waited 24 hours to ensure I had no other lingering issues, rooted the Gingerbread install and then my root apps. I'm not sure what phone you have but this was the only way out that I could find, I hope it helps you.

    These are the steps to boot your Droid 2 phone into Recovery Mode should you need to.

    Perform a hard reset on your Verizon Motorola Droid 2 if you wish to wipe all the data from the device.
    [h=3]From device startup[/h]1. Turn the Droid 2 off. If it’s frozen and you cannot turn it off, pull and replace the battery.
    2. Open the keyboard and press the X key while pressing and holding Power. The device will power on. Keep holding the X button downuntil a white triangle with yellow exclamation mark appears.
    3. Press the Search key on the keyboard (magnifying glass).
    4. Use the Volume Up and Volume Down buttons on the side of the phone to select the Wipe data factory reset option. Use the Camera key to confirm it.
    5. Tap wipe data/factory reset then tap OK.
    6. Highlight reboot system now is highlighted then tap OK.

    Here is the link to where I found the instructions to Hard Reset the phone:

    Droid 2: Hard Reset | Technipages

    There are similar links on the bottom for other phones, if you do not have a Droid 2.

    Good Luck.

    You must SBF, especially after installing a GB ROM on a Froyo kernel.
