Bricked E975

Hi there folks
I rooted my LGOG with the motochopper method and it gave me a lovely rooted device.
Then i decided to install Rom Manager and grant it super user acces.
When i rebooted after the rom manager had downloaded the recovery files it got stuck at
"secure booting error!"
Cause : boot certification verify
My problem now is ive got all the tutorial files found in this http://forum.xda-developers.com/showthread.php?t=2010624 post, but the original firmware program doesn't connect to the lg servers with my model number and IMEI.
Could someone with an E975 help me with a stock kdz so i can save whats left of the brick, it can stil do download mode etc and switch off.
Thanks in advance

Here you GO
http://www.lg-phones.org/official-stock-lg-optimus-g-firmware-rom.html

Well, maybe you will not get errors next time if you UNLOCK THE BOOTLOADER.Only rooting is not enough. You need root to be able to use FREEGEE,to unlock the bootloader. Unlocking the bootloader with freegee will also flash CWM recovery or TWRP, depending on your choice.
See what happens when you don't document yourself properly before trying to do things?

All is fine now, i couldn't download the KDZ since i edited my host file when flashing the L9 two months back.
Im waiting on the freegee support now. cheers

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.

Thank You schafi03
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.

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

Hello downgrande wokrs?

Tot or Kdz?

I want to clean wipe my lg g3 and install stock firmware. The two methods I discovered was kdz method and tot method. Are these two methods the best or are there other ways I don't know about? What's the difference between these two methods and which should I use to wipe everything off my phone to make it as if it was new from the factory?

You should use kdz as there are no tot files for the latest firmwares.

After some reading(I may be wrong, if someone knows better, correct me.)
tot files requires a dll file to be flashed.
tot files are released for upgrades that can't be downgraded. This makes sense for me as all tot files are from KK, there are no LP and MM tot files.
I never used lg flash tool 2014, only LGUP with kdz files and it works without issues.

Sorry this is confusing. KK is a downgrade from LP and MM. What do you mean by "tot files are released for upgrades that can't be downgraded." LG flash tool is easier.

I mean there are tot files for the first KK update, you can't downgrade lower than that, because that is the first one. This is my thoughts, I may be completely wrong here [emoji3]

is there any available file of kdz nougat version? im looking forward to upgrade my lg g3 korean version i have already 6.0 as of now there is no issue or bug from it

Downgrading LG G4 F500L from Nougat to LP or MM

I want to unlock my LG 500L(I guess everyone wants that right ) which is updated to nougat.
I tried to downgrading using the F500l20u kdz from lg firmware using LGUP but it failed at 11%.
Replaced the .dll file , still no luck.
Tried to go back to LP using the tot but it failed giving the unknown command error.
So if anyone of you who want to support the unlocking of LG g4 F500L with nougat can give me suggestions on how to go back to MM in order to flash the USU.
Flashing back the Nougat kdz works fine though.

Pls provide the exact way:
You replaced the dll: which do you use? Share the link. How did you replaced it? Write the file path you used.
You tried to go back to LP: which one? Share the link.
If you used the right dll you need to flash a MM based ROM first afaik.
what lgup version do you use? Shown at the bottom when started. Should be 0.0.4.0
I would recommend to change the title to something better explaining what you need (downgrade a f500 from N to LP).

I used the LPUp with dll version 0.4.0
I download the LP tot from this thread:
https://forum.xda-developers.com/g4/general/tot-lg-g4-korean-f500l-tot-flash-files-t3294417
I downloaded the kdz of LP and MM from here
https://lg-firmwares.com/lg-f500l-firmwares/
I followed the LP up refurbish option.
I tried the .dz file extraction and installation using the LPUP, still it gives the command unknown at 11%.
I used the latest .dll file from this thread:
https://forum.xda-developers.com/g4/help/lg-g4-lastest-version-lgup-dll-file-t3586220

Anyone who know the way to downgrade?

You better had posted in help forum instead of here. Report your own thread (button beyond your post) and ask for thread move to help section... Just a suggestion..
Besides that:
Have you tried that https://forum.xda-developers.com/g4...rying-to-flash-kdz-lgup-t3666486/post73642302
Yea I know it's for the h815 but it's known that cross flashing between f500 and h815 is no problem an if that works well then you go UsU anyways
Ah and yes you have to hexedit the kdz to make it flash on yours.

LMG820UM Problems

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

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.
