Tutorial: LG P970 (P970H) unbrick/flash using SmartFlash Tool

Arrow Tutorial: LG P970 (P970H) unbrick/flash using SmartFlash Tool

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.

  10. I had the "We can't communicate with specific port" and indeed putting the USB-cable in another USB-port did the trick for me :).
