[Q] bricked my phone

hi...guysss.......i bricked my phone how can i put zip file in sd card......no system in my phone or sdcard also been empty

Make sure all power is off, then hold both up and down volume and connect a USB cable then restore from kdz. Your phone is just soft bricked.

I assume you are using the flash tool for KDZ. try differents usb ports on your pc.. go to device manager and go down to ports and make sure that you see this driver : LG mobile usb serial port there.

LGUP - NEW!!! - INSTALL KDZ - MM or LP - FACTORY RESET/UPGRADE

NEW software!!!!!...... LGUP WILL FLASH YOUR KDZ files
Download LGUP from here http://www.filedropper.com/g4 or here https://www.dropbox.com/s/d2dw48uqh4hku8m/G4.rar?dl=0 or here http://oceanhost.eu/eps4h4pmwphu/LGUP.zip.htm thank you hyelton for this link :good:
Install LGUP_8994_DLL_Ver_0_0_3_23 first and then LGUP_Install_Ver_1_14_3
Make sure you have downloaded the required KDZ file MM or LP
Start LGUP prog on your computer "make sure your phone is plugged in"
ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.
THANK YOU FOR THIS Killerdog:good: <~~~To Modify This File You Must Have Root!!
For me it's show in LGUP as unknow device.
reboot my phone, remove battery and anything else don't work.
I install LG Bridge to test, and nothing seem to work.
After make some test and search, i find some info modified by S3V3N into his rom (cust partition) that he have modify into this file:
/cust/OPEN_COM/cust_OPEN_EU.prop
Code:
ro.lge.swversion=[COLOR="Red"]some info[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]some info[/COLOR]
change to
Code:
ro.lge.swversion=[COLOR="Red"]H81510c[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]V10c[/COLOR]
restart my phone and woow it show correctly in LGUP and i can refurbish my phone.
TO UPGRADE TO MM from LP - make sure BIN file is ticked and in the File Path point it towards the MM KDZ you have downloaded. MAKE SURE YOU HAVE CLICKED UPGRADE! This will update you from LP to MM with out wiping any of your info. Press Start. Make cup of tea and be patient
TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
IMPORTANT!!!!!!! shut down LGUP!
Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient
TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Make cup of tea and be patient
If you are worried about losing your data after a full wipe, why not use the LG Bridge software to backup and restore.... it works fine!
YOU WILL LOSE ROOT!
There is no need to enter download mode! LGUP will do it for you.

INSTALL TWRP
Make sure you have ADB and Fastboot installed.
I always put TWRP.img in the ADB folder - so if I want to boot into TWRP with out installing it this is what I do:
make sure you open a command prompt in the ADB folder "VERY IMPORTANT" and type:
adb reboot bootloader <enter>
fastboot boot TWRP.img <whatever your TWRP image is called in your ADB folder><enter> dont forget the .img at the end
That will re-start your phone straight into TWRP - You can transfer files to and from your computer while in recovery.
If you want to install TWRP permanently, copy your TWRP image to your mobile "while you are in TWRP RECOVERY mode" then press install then select images then select recovery NOT BOOT then swipe to flash. This method does not install TWRP app on your phone, all you need is a reboot app from the play store that will re-boot you into recovery.

Not sure but I'll put that in the op cheers.

Do you need root so use this method to upgrade to marshmallow ?

H81520A_00.Kdz flashed (by upgrade option) succesfully. It takes 10-15 mins(longest part is "android upgrading" screen.), and i lost root access. By the way root access is not necessary for upgrade.

So since it wasn't clarified, I'll be the one to ask...
Will this work on a unit without root (which is yes according to the OP), and without a bootloader unlock, ie the Taiwan (TWN) variant of the H815.
I completely understand it's a complete wipe and root will not be retained.

I would also like to know about this..... will it work on a unit with a locked bootloader... TWN variant?

downloaded from a different mirror re flashed no problems

LG G4 flashing CM13 Fail

Hello everyone. So, yesterday I flashed the new CM13 on my h815 international. I have TWRP Installed but CM13 has overwritten my backup, so I don't have a backup to go to.
Current state; What should I do? The only thing i need is to get into ADB/TWRP because when I start my phone, it crashes instantly. And USB Debugging isn't on, I cant enable it because i only see "System -UI" has crashed. ADB won't find my phone, not on usb 3.0 or 2.0. I tried to get into TWRP with Hardware buttons, that also didn't work.
My phone is rooted and has a unlocked bootloader. What should I do? I can see my phone on my Windows PC when plugged in. Please help

EDIT: I WAS ABLE TO RESTORE EVERYTHING WITH A KDZ. THANKS GUYS

I tried the Tool and KDZ. It means "no connection to server"

Which version?

Which version of the KDZ are you trying to flash? And chances are that your device isn't being picked up because of the lack of USB debugging.

Is that a lollipop version of the KDZ? I get that but the flashtool uses adb tools to flash.

Put your phone into Download mode.
You should be able to flash a .kdz then.

I have CM13 and can't connect to LGUP

How can i connect to LGUP with CM13? Either LGUP or LG Bridge sees my phone. Windows have no trouble connecting to the phone...

I have twrp recovery.
