LG Tribute HD LS676 ZV3 Stock ROM / Firmware Unbrick Guide

To boot your LS676 in download mode.

Turn off the phone
Connect USB Cable to phone
Press the volume up key.
Keep it pressed, and connect the other end of USB cable to the computer.

Now your phone must be in download mode. It would read “Firmware Update”.

Now run the LGUP program. It’ll show the connected phone model and its current firmware version. In my case, it’s showing LS676 ZV3, even though I’ve already updated the phone to ZV4.

Click on 3 dot icon below “File Path” to browse for the downloaded TOT firmware file.

Select the “LS676ZV3” tot file and open it in LGUP.

You can see the firmware file is now showing up in “File Path”. We’re now ready for flashing.

Click on “Start” to begin the process. Don’t unplug the cable till the process gets completed.

The phone will reboot on its own when the flashing gets completed.

It’s recommended to perform a factory reset after the flashing is done.

  1. Hello,
    I wonder, why I am always getting an error “Error: 0xD, Image file corrupted.” at 4%?
    No matter what the tot file. I have tot files for almost all versions, up to zv9, non of them work with the same error.
    Please help.

  2. I downgrade my lg ls676 zv8 to zv3 tot software mistakenly and now the phone does turn on but give connecting sound on pc but phone is blank. please is there a way out

  3. i get the same thing: Error: 0xD, not support diagEnable for laf mode. how can i fix this damn thing. any help is appreciated. thank you very much.

  4. Hi, I’ve updated to v5 by accident. LGUP sees the device as v3. When I try downgrading to v3, it stops at 4% and says something about unsupported diag. I have the MSL and already selected diagnostic enable.
