[Q] Help! LG FlashTool is not working for me. topic

I am trying to flash an older version of the G3 firmware using the LG FlashTool. The first time around it failed and no my phone is stuck on the troubleshoot screen. That's the only place it boots to. Each time i try to flash, it randomly stops and tells me it can't communicate with my phone. I downloaded all files for my variant and i installed all the needed extensions and apps. Can someone please help me with what might be wrong? It would be greatly appreciated. Thank you!
