Charge battery to about 75%. Disconnect cable from anything. Make sure the phone is turned off and full computer installed drivers for your devices. Press both volume keys at the same time (Press Volume - and Volume +). Connect cable with Computer. On screen of phone will be display logo: DOWNLOAD MODE. done.
Run Flash Tool or KDZ Tool, then flash file ROM do you want. Good luck!
Power + volume down will get you the LG factory reset.
Thanks for your help !
the problem has been solved
bye and thanks
hello geeks,
I really need serious help. First the setup I have is as follows
1. I have LG G3 D855 but its european or Hong Kong or Taiwan version I don't know. I bought it in India. I updated it to android 5.0 Lollipop. Everything is fine till now.
2. Then I rooted my phone. This step was also fine. No problem.
3. Then I tried to download camera mod v2.0 to get some extra camera features like 60fps. In this step I got problems. I downloaded the media_profile.xml and copied it to /system/etc. But I made a mistake that I did not change its permission and rebooted the phone.
I am troubleshooting from a windows 8.1 PC. I downloaded the LG USB driver.
Due to this my phone stop at initial LG,Life is Good Screen. I tried different methods in internet.
1. I tired to access the device file file through adb. But the adb does not list the device.
2. I tried to use fastboot mode, but still fastboot does not list device when in the boot screen.
3. I pressed down pwr + volume down button and release after screen come up and then press again. I was asked to erase user data. I said yes and it erased the data. But still the same symptom when I reboot. Stuck at initial screen.
4. I tried to use LG PC Suite. But it does not even detect phone through the USB and there is no repair button.
5. I tried to enter downloading mode. This one is strange. I pressed down the vol up and then connected USB. But sometimes only it enters downloading mode and sometimes not. May be once in 10 times it enters downloading mode and 9 times it goes to initial boot LG screen.
I am not sure whats going on. Can anybody help me to figure it out ? Please help.
Thats because your not doing it properly
Research a guide on how to enter download mode and after that you can use flashtool to wipe your system and reinstall the original lg firmware

FIRST install the DRIVER from this thread: http://forum.xda-developers.com/showthread.php?t=2785089
See in the part 2015 with TOT files...
(if any other drivers are present, uninstall them and do a clean install)
You need to get in Download mode to be able to fix it without having to open the phone.
1. Unplug phone from pc and power off
2. Remove back cover and remove the battery
3. Plug the micro-usb cable into the phone
4. Press and HOLD the VOLUME DOWN (make sure you press it from the edge, far from the powerbutton)
5. Put the battery - Dont let go of Volume Down yet.
6. Connect the micro-usb cable to the pc - Dont let go of volume down yet
7. Wait for the pc to recognize it, and the download mode appears on the phone, now you can let go of volume down
Repeat again, first time might not work.

PS, quote me because i might not see and answer then. good luck

You're still soft bricked, just force your device into download mode and use LG Flash Tool to return back to stock and start again.

Thank you for the respond. Mind if you share me on how to force my device into download mode?
I have tried the power + volume keys combination but nothing happened, back and stop at lg logo
Before i flash the twrp, i tried the LG Flash Tool, but i wont recognize the phone, something like usb connection issue

If I remember correctly (please check threads here, it's been a long time since I've used this device, so memories are fading), download mode is activated when you press Volume Up (or both of volume buttons) and insert USB cable. I know that E98x has some strange button sequences, like rebooting to recovery is a two step operation (Volume Up + Power until navbar blinks, then power button twice, that's the only way mine wanted to boot into recovery), so please check around.
As far as USB connection issues, don't use USB3+ ports and if you're on Windows 8.1+ and later, run with Administrator privileges. I never experienced that one (used LGFlashTools from inside VirtualBox running Win XP for all my needs, I'm not a Windows user), so can't really help much but forums are full with explanations how.
