Fast boot mode started, can't go to download mode

Hi Everyone
Sorry for my not so good English.
I have problem with my G3 and maybe someone can help? I instal root without problem, than I try to install Twrp recovery and after that I have that message ( [780] fast boot mode started) all the time, I try to do hard reset, click yes twice, but getting the same message, Is there any chance to unbrick that device when I can't go even to download mode?
Thank You very much for any suggestions

help!
help my G3 died the same thing happened!

same to me...

What model(s)? Youll need a pc, adb/fastboot, stock laf.img and boot.img for your device. Youll use adb commands to erase these img files and restore them with the new ones. Once you have adb running and recognizing your device with both files in same folder as adb you'll type adb erase laf [Enter] then adb flash laf laf.img [Enter] do the same steps for the boot.img. Next type adb reboot [Enter] you'll still be in fastboot but just pull the battery. Then replace battery and you should be able to enter download mode by inserting the usb and pressing vol +(i believe, it's been a while) and then kdz flash..

I can see a different screen for a split of a second but it's going back to Fastboot mode...

@SaharLevi
Here's the fix Quick and easy
need to have fastboot, I used ubuntu can install with sudo apt-get install android-tools-fastboot
info on fastboot
[TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer
also need recovery.img, I used the lastest twrp
In terminal
fastboot boot recovery.img
this will boot your phone with the img on your computer.
in recovery restore or install a good boot or kernel.
your phone should be good to go after that.
I had my phone fixed in about 5 min, I really should not play around with boot partition.
Also should be able to flash boot if you have a good one,
fastboot flash boot boot.img

Mine has too after installing the official Lollipop, any help? Lollipop was buggy for me so I'd like to unbrick my Oppo.
So plug in phone AFTER booting into Fastboot mode (power+volume up) then open a command window by pushing shift and right clicking anywhere that the platform-tools folder is and then type fastboot devices and hit enter and then type fastboot oem unlock and hit enter and then fastboot flash recovery recovery.img or whatever the name of your rcovery is then just power+volume down and boot into the recovery. It helped me!

LG G3 Bricked / No ADB / No download mode / No recovery

Hi,
Since the rom ( http://forum.xda-developers.com/lg-g3/development/rom-resurrection-remix-lp-v5-5-5-t3198675 ) of my phone crashed. After reboot, the phone is blocked on LG logo. Now, i can't enter in recovery mode (or in the download mode) and when I start my phone, it's fixed on the LG for 5 to 10 minutes, and after that it goes to a terminal (started fastboot mode).
I have read several tutorials to use fastboot to flash the recovery to reinstall a rom, but i have a error when i tried to erase or flash the recovery partition.
I look on my phone, and this error appear : "failed to send erase grp start address".
what can i do to fix this error ?
Thanks.

up please

Use the "boot" command instead of "flash" and it should boot up into recovery or downloadmode, depending on which file you use

I tried but i am stucked on teamwin logo.
Which file do i use for download mode ?

Hard to tell, there are some laf.img files floating around on xda and google or even better, extract the laf.img from the stock kdz depending on your android version (for instance you flashed 6.0 you pick the 30b kdz and extract it with the firmware extraction tool)
I would suggest you to and try to use the boot command with them..
Be carefull, do not use the flash command until you found one that boots into downloadmode properly or you can loose your fastboot mode aswell
From then on you should be able to boot into the downloadmode and flash a new firmware via the lg flashtool

I need help please. What can i do to re install a rom ?

Does your PC recognise the port.?
I found tutorial under bender_007 signature. People seemed happy with tool.
http://www.androidbrick.com/unbrick-recover-your-dead-lg-g3-g2-all-variants/
Doesn't hurt to read and ask some questions.

no i can't connect my phone with port. I think, i nned to correct the error with fastboot. (remote : failed to erase partition)

Can you elaborate, how exactly your phone crashed, it is very unlikely that it will mess all the partitions just by crashing the rom?

The rom crushed twice, and now i can not access to recovery to install a new rom. I only have access to the fastboot command. Adb not working.
I tried to boot on recovery.img, but it's not working.
Thank for your help.
Regards,

Help please ?

Today i can connected to my phone with ADB when i tape this fastboot command : fastboot boot ./recovery.img.
I can too go into my phone as root with adb command : adb shell.
i tried to push flash_image on my phone and use it, but it donesn't work.
how can i flash my phone with adb command ?

fastboot flash splashscreen splashscreen.img
fastboot flash ifwi ifwifilename
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash fastboot droidboot.img
fastboot reboot bootloader
now use volume button to find recovery mode option. click power button to enter recovery. you will enter recovery
( note: if you see an error screen with android logo. at that screen click and hold power button and then click volume plus and release power button you will enter recovery)

Dude, you just should flashing original/stock boot.img and recovery.img. And your phone already fixed.

Jus flash vbmeta and than flash twrp again . It will work fine and you won't get erro

Flash vbmeta

where did you got the file?

I have the same problem. Also cant flash vbmeta because the phone cant go into fastboot/recovery mode. It seems the only option is to flash it in edl mode and haven't found a tool that can do that

You have to flash the boot.img via adb to boot into Fastboot or Recovery.
