[Q] Cannon update on rooted phone

Hello guys! I have rooted optimus g, official firmware, unlocked bootloader. I tried update to the new
kitkat update, but after the download,when installing,an error coming up. Then the phone restarts
and a messaga that i cannot update because the phone may be rooted appears.
I unistall root via superuser settings but the problem still exists. So is there any way to update
to official kitkat? If not, if i flash official 4.1 can i update official? Will i lose my archivers,
contacts,apps e.t.c on my phone?

A assume you installed custom recovery so official update can't execute with it. Just flash KDZ.

Thats right, i have cwm. If i flash kdz,will i lose cwm until root again? And should i flash kitkat or 4.1 kdz first?

Connon update I thought you've used Cannon camera update fo OG camera lol
Try flashing Kitkat 20b using Flash tool 2014.

[Q] Secure Booting Error! Cause: boot certification verify

Hi,
My phone specs:
LG G3-D855
Android-version 5.0
V20E
Today I rooted my phone with this guide:
http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
Everything went well and got my phone rooted. After that I tried to install TRWP, except I missed a line in that guide and got the error above.
"I saw a lot of questions of G3 users about how to install Twrp after the root, so I will explain briefly:
For now, if you are on stock lollipop you can't just flash Twrp via flashify etc like the old days in KitKat,"
So I did use Flashify to flash TWRP and got the error and I'm unable to go into recovery mode.
Looked up on google on what I can do to fix this problem and found this:
http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/
In this guide they say I can download the LG G3 Stock Factory Firmware. Looked for my version and they listed:
Android 4.4.2 V10E LG G3 Stock Firmware D855 European 16GB
Except when I look into my phone and look at the version it says V20h-E, would that be a problem when I use the V10E?
Or is there another way to fix this problem?

@Midway6
only one method I think : http://forum.xda-developers.com/showthread.php?t=2785089
When you flash on Lollipop a twrp without dowgrade aboot and laf and no bump boot , your G3 is blocked.
First you root your G3 : http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
Then you use Autorec , the apk from @bender_007 : https://play.google.com/store/apps/details?id=b007.autorecd855

Does that mean I can use the V10E with my V20H to go back to stock?
Nevermind I found the V20H in the Lollipop V5.0 folder. I'll use this one
http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/Lollipop+5.0/D855/
Gonna try the link you gave me. I'll report back when I tried it.

you can apply the 20H kdz yes, then you root and use autorec.

I did that method so far so good. Waiting for Android to finish those upgrades and I'll root again.
So first I'll use that one click root method and after that I use Autorec application to install the recovery?

Yes exactly.
Before autorec, this method worked well but since bender_007 develop autorec for the G3 I recommend it

Thanks a lot! You saved my night
So now I can flash new roms and stuff and if something brakes again I can use this method to restore my phone.

I'm getting a error while flashing.
Checking for MD5 file...
Skipping MD5 check: No md5 file found
Error flashing zip '/external_sd/.........zip'
Updating partition details...
done...
Failed.
I've never heard of a MD5 while flashing a rom.
How can I fix this problem? Is it necessary for flashing?

I never check md5 on twrp because I have always this error message. So flash the Rom without md5.
Before backup the Rom stock with twrp

You can flash the kdz (stock file) for the update you have available by using LG Flash Tool 2014 (do a Normal flash).
The instructions and tools required for flashing a KDZ file are in this thread
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
The steps are roughly:
1. Find and download the correct KDZ file for your phone by following this link (replacing IMEI at the end with your IMEI)
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
2. Flash the KDZ using LG Flash Tool 2014
3. Once finished flashing and the phone has rebooted, re-install TWRP and flash root
Cheers.

Thanks I'll give it a try

False information shared by @Ernesto0023.
Following this guide will get you a secure boot error when attempting to boot into recovery. Even so following this guide is impossible because root is required and OP has no root on his kdz flashed MM.
My recommended solution would be reverting back to kitkat via kdz. If unfamiliar with the method follow this guide: http://forum.xda-developers.com/showthread.php?t=2785089
After reverting use the guide from post above: http://forum.xda-developers.com/lg-g3/orig-development/recovery-twrp-touch-recovery-2-8-2-0-t2966129
to flash TWRP.
Then fell free to flash whatever you want in TWRP. If stock lollipop ROM is you what you desire, download zip from here: http://forum.xda-developers.com/lg-g3/development/stock-t2961073
if stock MM is what you wish for download zips from here:

You can't install it because you don't have root and it is not for MM availible yet

But with root and installing over ADB should work, or not?
I mean root isn't a Big Deal on the G3
Edit: Sorry, now i recognized its the unrooted official MM - maybe to much partying yesterday

Yeah
Even so if his MM would somehow be rooted it was still kdz flashed so it contains
MM bootloader. That equals BUMP not working.
Hope you had fun.

Happy New Year to everyone here!

My phone doesnt want to downgrade. I stuck at download mode. I put my kdz file to lg flash tool and start it. After starting, lg mobile support comes and analyses phone. After that it says Upgrade stopped due to an error. I flashed mm yesterday! Phone opens normally everything works. No problem on recovery too (stock one). But i cant downgrade to lollipop! Please help!

How did you try to get into download mode? Twrp can boot into download mode and also did you try the manual method to get into download mode?
Also how did you you flash the kdz because technically when you flash a kdz it should wipe twrp recovery and return you to stock recovery.

Internal storage is empty and the download mode don't go, I flashed the same firmware for unroot the phone but don't go. I've tried doing this http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 and the phone goes.
