guilardi, can I flash the V20O ROM from Europe on P970H? Is the .bin or .fls files ONLY the baseband? My idea is flash the system more recent, the V20O makes the video call from GTalk...
I lived in Campinas from 2009 to 2010, and I miss this city... I worked in The Army, located on Anhanguera.... I'm in Rio now, I'm carioca, but I want peace... Crazy life in Rio... many missions...rs
thanks!

Does not work

Please help me with my LGP970. The above method doesn't not work at all. Any other way to save my phone? D: I flashed with different kind of F/W from Singapore Service and none of them work too. ( Including the one provided in the post above )

    SmartFlash Tool completly erases device memory during flashing.
    Phone will make Factory Reset at first boot after flashing!
    You can upgrade and downgrade. You can downgrade from V20N too!

    This also will remove phone lock if you forget unlock code or pattern. (phone lock, NOT simlock or network lock...)

    This method doesn't need internet connection. :)
    If you want to flash an LG P970H download correct ROM from link below.

    With this solution you can unbrick LG Optimus Black P970.
    It fixes bootloop, "ERROR LG Security Team", and BSOD - blue screen with green writings (untested).

    Only requirement is ability to enter in to S/W Update mode and not broken hardware.

    Tested on: Windows 7 Ultimate x86, x64 and Windows XP Pro SP3.
    ---------------------------------------------------------------------------------------------------------------

    Downloads:
    - SmartFlash Tool (mirror) [password: radkor@XDA]
    - stock ROM V10A EEU XXX with .bin & .fls. [CRC MD5: d880b8834400575b5827bafbf29a745e] - DepositFiles, FileServe, WUpload.

    Other bin/fls ROMs are HERE. (All these links are working again!)


    You need to install LG Mobile drivers. They are located HERE. [CRC MD5: e4614071e72c0292d3a8238908b5c7ba]

    1. Unpack SFT.rar that contains SmartFlash Tool program.

    2. Unpack, preffered C: drive, firmware pack BIN_LGP970AT-00-V10a-EEU-XXX-MAY-09-2011_0.zip
    Inside there will be 2 files: LGP970AT-00-V10a-EEU-XXX-MAY-09-2011+0_AP.bin i LGP970AT-00-V10a-EEU-XXX-MAY-09-2011+0_CP.fls.

    3. Run B_SmartFlashTool_Extern.exe

    4. Choose:
    1) ROM copy D/L bookmark
    2) in Select mode choose Normal mode
    3) choose CP file: LGP970AT-00-V10a-EEU-XXX-MAY-09-2011+0_CP.fls
    4) choose AP file: LGP970AT-00-V10a-EEU-XXX-MAY-09-2011+0_AP.bin
    *) connect phone in S/W Update mode with battery in it (on the phone that is switched off, plug in USB cable WHILE HOLDING Vol+ button)
    5) choose COM port.
    6) choose LGE Mobile USB Serial Port in Communication Driver
    7) click Start and wait till end.
    It takes about 3 mins to flash.

    After successfully flashing, phone will reboot and make Factory Reset.
    And that's all! :)


    Settings:

    Flashing:

    Finished:

    Now your phone should be unbricked and working.


    I will not take any responsibility if something goes wrong when you trying this solution. For me and many others it worked well.

    To add, it is a fast flasher compared to RDTT. :)
    Exactly! It takes only 3 minutes to flash. :)
