LMG820UM Problems - LG G8 Questions & Answers

I have the LG G8 from Verizon. About a year ago I was trying to root it and got so frustrated with it that I ended up deleting all the partitions on. So bad that all it can do is go into edl mode. Well today I downloaded the chinese kdz tools and I've used it to extract I think dz to dz. I don't know what to do with the G82010g_00_VZW_US_0918_img file it made. Please somebody help me get my phone back to working.

So, bad situation, as you know. Follow this link to a windows based kdz extractor tool.
Hopefully that will extract your vzw kdz. If so, flash abl, boot, laf and dtbo partitions to both slots using edl. That should give you download mode so you can use lgup to refurbish the vzw kdz.
I've never had to do this, so not sure what the result will be. Since you deleted all partitions, I don't know if they will be 'rebuilt' completely, with imei etc. But at this point, you've nothing to lose.
good luck

you said you deleted all partitions didn't you? How did you do that? It was edl mode and qfil wasn't it? As that's what's in guides section to root device.
that's what you use. Except this time, don't make the same mistake. This time, follow the guide to and flash partitions.
there are no other ways.

Yea but they were already there in the partition manager

You don't need the H810 KDZ... All you need is the modified VS986 IMG and a few commands.

Did you follow this thread? http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
I did this step by step. The only files you download/need are the VZW LG drivers, the LGG4_Root zip (using send_command and adb files in that zip), and the 11A VS986 IMG file.

I followed the directions so never got that error, I'm not sure what your best course of action is. I highly doubt you'd want to flash the KDZ for a different model, you'd probably brick your device or cause major issues if it works.

well the reason I got that error is because I used the h810c and my phone is the h810e. So Im going to have to wait until the h810e kdz is out.

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

KDZ Upgrading enquiry!

Hey! So I am a noob in Lg G4 developing and stuff!
So heres the question, I don't have rooted system or unlocked bootloader, so if I were to Upgrade my G4 H815 from 10D to 20B , what files will I have to flash, like I am downloading the system file , do I also have to flash the modem bootloader Boot , or is the system file enough ?
I am using lg Up to upgrade, so I have no idea what am I doing
All you need in the right kdz file you want to flash and LGUP software on your windows computer.
Thats it...
Good luck.

Question Bricked my OP 9 Pro TMB

Hi XDA Community,
I soft-bricked my phone, it gets stuck on fastboot even after flashing my backup. The only thing I didn't backup is my userdata partition. Does anyone have the T-mobile firmware so I can unbrick?
Thanks
MSM doesn't exist for T-Mobile yet. Did you try fastboot -w to erase all userdata?
Yes, nothing so far. However someone out there can probably dump their tmb firmware and I can use fastboot flash.
I fixed it!
Looks like the vm-bootsys file was responsible, so flashed that and good to go!
Nvm, now stuck on wiping
EDIT: It's doing the same thing again
Unfortunately, TMO MSM doesn't exist currently, and full OTAs are not available, so there is no good way to extract /system, /system_ext, /vendor, /product, and /odm from super. It sounds like you backed up everything though, so what happens if you just flash everything back?
Hey I might be able to help you dude? I pulled my tmo firmware as back up. I mean I pulled every partition and made a flashall.bat if I knew how to put it on a site or share with my drive it's 20gb.

I extracted all that even vbmeta_vendor all partitions. If you can tell me how to send it to you I will let u look over everything and I can see if it will help ppl. I used it to get my 9 pro unbricked. I got the convert to us OnePlus os in. I just can't update yet.
Yes I would very much appreciate it. @craznazn I will convert to EU as a last resort, that's what I was actually attempting in the first place! Thanks!
You can zip it using something like 7-zip and put it on anonfile, they have 20GB limit but compression makes the folder size smaller. Thanks a ton!
Or you could use gofile, unlimited storage space.

Did you get this backed up online yet by chance?
I want to flash Global myself but waiting till there is at least something to attempt to flash to fix if it breaks.
I flashed EU, am A-OK apart from maybe downgrade to L3, still working that out.
Also, you can back it up yourself using Partitions backup and restore on the Play Store. Just make sure you are rooted, otherwise it won't work.

What partitions did you backup using that app and were you able to successfully restore using that app as well? Does the BL remain unlocked after restore?

He's running an experimental MSM conversion I built, it's not public yet. It does not touch the BL unlock. The process is not stable and it's not ready for public use.
That, and it's no longer the TMO ROM, and there is no good way back w/o an official LE2127 MSM
I am gonna try to write a guide my first one if I am not breaking any rules. Anyone can tweak or down it? But like I say messing with android is trail and error. I am gonna put the. Rom I pulled and used to unbrick while y'all are waiting on the msm. To me. This is just an easy fast fix so look out for it on the guides.
I backed up everything except for userdata. Make sure you manually dd the super partition to a super.img, otherwise it stays a tar. That's the mistake I made. I'm sure I can convert it but prob not worth the hassle.

Did you root your phone? If you did, you can use Qfil to restore your stock boot img (if you made a backup). If you didn't, you'd have to get someone to send you their boot image. I would have sent mine, but I cross flashed from Sprint to Open US. I doubt mine would work for you.
Why can't you cross flash?

You should clear modem and some other files stated in that post. Then you select all partitions in LGUP except one file also stated in the post. (I can't remember the name of the file)

yea i cleared the files mentioned in that post. and also cleared modem. Any kdz i flash, the first message i get is: this phone is permanently locked. it can not be unlocked. before this i tried some guy's backup from TWRP of his lg g8 sprint. i got lots of errors popping up when it booted. i think that's where my sim whatever got messed up.
From my research, i think a file called fsg has something to do with sim working. Also my IMEI is 0. any suggestions would be highly appreciated.
