[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

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

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

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

Even so if his MM would somehow be rooted it was still kdz flashed so it contains

[Help] How to Downgrade F500l Nougat 7.0.1 to Lollipop 5.1

Right now I am using Nougat v30b in my LG G4. I want to downgrade my phone to lollipop to root it. But I can't downgrade F500L using LGUP. The anti-rollback version is 0.
Whenever I tried to flash v11d (Lollipop firmware) TOT file using LGUP it gave me an error code = 0x2000, invalid command response and stuck at 23% (LGUP Step showing: System) and if i change the dll file I get same error at 11% (LGUP Step showing: PrimaryGPT)
I have tried uppercut, usb 2.0 and changed cable but the problem remains same.
I don't know why it is giving an error, maybe due to wrong .dll file or may be due to some other reasons.
If I tried to flash v30b (the version I am using right now) using LGUP then it didn't give any error and the flashing gets successful.
I tried LG FLASH TOOL but it stuck on 9% giving DoDownload Error!!!
Please help me to downgrade my phone to lollipop.
If you know anything which may help, Plz let me know.

I think you can´t directly flash a Lolli Rom. First you have to flash the latest mm, than you can try to flash Lolli. Maybe you need to flash after the latest the first mm Rom.

Afer this I tried to flash that kdz file using LGUP. Now one thing happened is that the flashing tool stuck at 37% (stuck when flashing system files)
I have also extracted the .dz file and tried to flash it but this time also it stuck at 37%

It's important for you to find the similar Rom for your Model. For h815 int it's named.

Same here on stock nougat 30b f500l we cant downgrade if the anti roll back version of the rom we are flashing is not the same in nougat anti rollback version

[H930] New Pie build V30q with Sep 1, 2019 security patch is here!

Running this build since last weekend and is fire.
I can confirm performance(like RAM management) and smoothness are improved, the overlaping notifications is fixed as well and even LG's terrible gesture navigation implementation seems refined (I recommend using FluidNG to have back gestures as a complement). Battery is fine tho
Please don't try using OTA if you're rooted.
If you are already on PIE V30B rooted IS EASIER to Backup you data, Restore the provided TWRP v30q BACKUP, then RESTORE your data and root . Latest stock version and all your data intact.

Is indian jio volte working on twrp method?

Just a reminder: You cannot use a OTA file if TWRP is installed, the bootloader can be unlocked, but you must have stock recovery for this to work. Refurbishing V30b is advisable.

Hey thanks for the procedure.
can you please make a system dump? It'll be useful for los16 with pie blob development?

Congrats to the five V30 users who will get this update.

Can I flash .kdz file with "Upgrade" (NOT Refurbish) option without losing any data? Cause I can't begin an update (the FOTA EASY UPGRADE shows for few seconds and disappearing with no results). Of course I'm working with V30b-EUR-XX version.

error comes out "windows cannot find WPDAPI.exe make sure you typed the name correctly, and try again" and press ok then new error comes out "0x2000, fail. mtp is not running." I can't update, please help me.

This is for people who want to run leaked, beta -- possibly buggy -- firmware. Yes, some people want that. If your wish to experiment, then that's fine as long as you realize it's not necessary to get this update...
When it's ready LG will release it officially and there will be full image KDZ available in the KDZ thread, as well as TWRP flashable zip made by an XDA Dev.

Buggy or not. I'm already using 30b. I have a chance to do it and I want to. Don't write me if you won't help me.

I provided a TWRP system backup, I believe it already does de trick right?

Can I flash .kdz file with "Upgrade" (NOT Refurbish) option without losing any data? Cause I can't begin an update (the FOTA EASY UPGRADE shows for few seconds and disappearing with no results). Of course I'm working with V30b-EUR-XX version.

You can flash H930v30b via upgrade, yes. Then send the OTA via LGUP.
Are you rooted?

WPDAPI.exe is a file provided in LGUP zip in OP, you have to patch the files in LGUP directory for this to work.

1) I'll write what I want in reply to anyone I want. It's not just for you, it's cautionary tale for anyone. Just make sure you know the risks.
2) EU H930 V30b has long been official. There's a full image KDZ and XDA Dev made TWRP flashable zip in MY KDZ thread -- so your statement makes no sense.
So what if you're running official publicly released firmware? What you're now trying to install is not officially public release firmware (yet, and no absolute guarantees it will be).

I used V30b by KDZ install and it was as buggy as the v30b OTA that I had used for a while too.
This V30q it's a huge improvement over the old version and I can say it with sure, because I have tested all these.
BTW, it's not beta anymore(is in internal test phase), they are just delaying the release with bussiness bureaucracy.

Please don't try using OTA if you're rooted.
If you are already on PIE V30B rooted you have to Backup you data, Restore the provided TWRP v30q BACKUP, then RESTORE your data and root. Latest version and all your data intact.
