SFT does flash the unlocked bootloader once u flash Froyo or GB so no need and also no way to unlock our bootloader.

I have a LG Optimus Black that is stucked on LG Logo, I did this tutorial and it was flashed successfully, but.. it's still stucked on LG Logo. The 3 buttons below are flashing and I cannot even charge my phone (it stucks on LG Logo again). I got 2 LG P970H's bricked this way, I got them with Android 2.2 Froyo Stock ROM from VIVO (BRAZIL) and the problem happened one day when I was using my smartphone normally.

Please can someone help me with this?
...

Hi seems I got the same issue, did you get if fixed?

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: [email protected]]
- 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.
