hold volume up and connect to pc -- download mode starts up?
if not -> connect to pc and see what happens -> also open up device manager if you´re on windows machine.

i did succeed, thanks to these!

If you are using Vista, it won't work. You have to do the update using a Windows XP computer.

First a few questions.
What OS is running on the laptop?
Does the computer recognize the device in download mode?
If yes, what does the device manager say that it is, under the "PORT (COM & LPT)"?

My G3 D855 won't boot

I'm rooted and have made a have few changes to my phone in general, but now it won't start up. It gets past the LG logo but then gets stuck at a black screen with the LED's cycling colours.
I've tried to factory reset it but it still gets stuck at the black screen. How do I fix this?
I has this a few days ago.
To fix it you will need LG mobile drivers and LG PC Suite installed.
Power off your G3. Then start it in download mode by holding the volume down button and connect a USB cable to your phone. The screen should show download mode. Connect your phone to your computer and start LG PC Suite. Don't worry if PC Suite doesn't recognise your G3. Go to the mobile device menu and select restore upgrade errors. PC Suite should download the latest firmware and install it. You will be back to a factory reset but your G3 will be working again ☺

I tried to fix the update errors but it said this update is not supported by Mac OS. I don't have a windows PC to use so what can I do now?
I don't have a Mac so not sure if this will work but search the G3 forums for advice on flashing a .kdz firmware directly to your phone. Make sure you find a .kdz that matches your G3 variant i.e. 16 or 32gb. Sorry but don't know if there is a Mac tool to do this. Good luck.

Thanks, Ill check that link out.
I'm finally on a PC and went into download mode but now my phones stuck at 0% doing a firmware update. It says don't disconnect the USB until the process is complete but I think I'm going to have to
When I did click fix software errors it said there were no errors to fix but I don't think I have all the drivers installed yet.
When I try go to download mode it keeps taking me to the firmware update screen and stays at 0%. Also the drivers aren't fully installing on this computer for some reason.

Install the LG united mobile driver first then LG PC Suite. Might be useful to reboot the Windows machine after that. Try having PC Suite running when you connect your G3. PC Suite might nag you about being unable to connect to your G3. Just cancel that and select restore upgrade errors. PC Suite should download the latest firmware before it flashes it to your phone. Check that your G3 is in download mode before you connect it to the Windows machine.
I'm assuming you've checked obvious things like turning off any firewall software that might block outgoing connections...

There are drivers and PC Suite for Mac on the LG website. That was all I needed to recover my G3 on my PC. I would try installing the unified drivers and PC Suite again. Start up PC Suite. Put your G3 in download mode and connect it to your Mac.
If that doesn't work and the unified drivers and PC Suite won't install on your friends Windows machine then I would run chkdsk and the system file checker.

I've got the drivers and PC suite for mac but anytime I try to 'fix update errors' a message comes up saying 'cannot run updating. Check device status and retry'. Then when I update the suite to the latest version, the 'fix update errors' option disappears from the menu. Ok I'll try those out on my friends PC when I have the chance.

how?
1. I've installed LG Bridge with all USB drivers.
2. Powered off G4 connected to PC by usb cable, it turned on automaticly.
3. LG Bridge can recognise phone when it has bootloop, it has not to be full powered on.
4. I've tried to update phone, but not successfully. It said that phone is up to date.
5. So i took troubleshooting option( not sure how it is called in english version of LG Bridge but you will find it)
6. LG Bridge have installed Marshmallow again, even without any data loss.
7. Phone is alive again after more than hour of updating (!)
8. Be happy
Will try on my h815 tomorrow morning when I get in from work

i think you are lucky, because you are in poland, where is official mm
Unfortunetly, rest of the world LG Bridge trying to install only LL.
So what? if you have LL and bootloop you can try this method also. It will re-flash 5.1

This didn't work for me. LG Bridge just says the phone has to be in MTP mode to accept connection or something. And then says it's not connected. Any clues?

Well. LGUP seems to have done the trick! Thanks for that info. It seems LG Bridge couldn't connect because the MTP driver failed to install with the phone. All other drivers installed correctly though.

Try volume up+connect phone to PC. If it isn't detected try charging it for 30 minutes and then the same thing. If that doesn't work try a different USB cable and/or different USB port on your PC.

That sounds exactly like the situation I had. Your motherboard is probably fried. Get it to your service center. Especially if you have the warranty.

I was in the same situation. For me sometimes I got port 9008 and sometimes USB device not recognized. However every time I got a Sahara Fail. Keep trying to flash the s288 row with different cables/ports. That's all I can think of.

he just said he heated on the memory chips or something like that .. apparently the flashing problem was my win 10 device . because once the phone show 9008 com on flashing software the flash process went ok on his win 7 device
There's another thing that I would like to add. When the flashing fails and phone becomes dead(seems dead), it is not in a powered off state i.e. it actually is in a dormant state in some occasions. That is, it doesn't respond to any actions performed like plugging to pc, plugging charger e.t.c.
For older phones with a removable battery, we could simply remove the battery and turn the phone off completely before trying to flash again.
But since newer phones like our Vibe P1 doesn't have a removable battery, we need to switch the phone off manually.
There is a method for that given in this link.
