hi
very helpfull, but i am a little stuck. my lg is stuck on the lg logo. used this method but problem is my laptop can not find the phone even sfter installing lg drivers. it shows LGE ANDROID MTP DEVICE NOT INSTALLED. Due to this problem the firmware updrade does not start. can you help with any suggestions.

My tool just keeps failing, I retry and then it tells me to Exit. Phones stays on the firmware update screen and nothing changes.

I did this yesterday and my phone is overheating and restarting like today it's better, what might be the problem

[faizaneast]

Can it work if I have the LG drivers preinstalled on my PC? Or do I need to install PC drivers only while my phone is connected to the PC in download mode? Thanks mate
