Hi, I am new to the whole root/custom recovery scene so don't really know what I'm doing, so I tried to use Flashify to flash TWRP on to my international LG G3 running 5.0 (rooted). Unfortunately, when booting into recovery I got a small message in the corner saying Secure booting error! Cause: boot certification verify, before my phone screen went black and my led started flashing blue and red. Holding down the vol - button seemed to fix it and the phone still boots fine, but it does this every time I try to boot into recovery. I just want to play around with custom ROMs and TWRP
Anyone got a fix for this, or know what is going on (bearing in mind that I am a complete noob with this stuff)?
Thanks in advance

I believe you need to use imageprep.

Are you sure it'll be safe, given my current situation? I was led to believe it was an error that I'd only be able to fix with a factory reset.

I have used this method and had no issues. The reason you can't flash it with flashify is because it only works on KitKat for lg g3. People using lollipop has to use image prep method. There should be two tutorials,one for going back to kitkat and one for alowing you to flash it while on lollipop.

OK, just had a read of the Imageprep post and this all seems completely beyond me. Is there an alternative method, or if not, could someone simplify what I'd need to do with Imageprep to get TWRP working on 5.0?

I have a E988 indian version which is stuck at boot with the "secure booting error cause : Boot certification verify",
I can get only into download mode and no recovery or can not boot into OS,
Earlier when i was in the situation i could get into download mode and use LG support tool to flash stock, But now i am getting battery low error..
My question is "Is there any way to recharge the phone if stuck at secure booting error or in download mode ?"
I tried offline KDZ flashing also but there also i was getting battery low error.
Thanks
If you can get to recovery. Mine charges while in recovery.

Try a factory reset by holding power and volume down at the same time. Press power button to confirm reset. If you do this, sometimes it will reboot you in to recovery, if not try it again and this time manually enter recovery.

I hate that stupid low battery message. It's so dumb that they do not allow you to continue at your own risk. I have also had this problem going from AOSP back to stock. The only safe way to do it is using LG Flash tools first, then flash one of those stock zipped roms. Now it is too late for that. Do they sell your handset in the country you live in? If so, they can fix it in store in most cases. For me, they don't sell this phone in my country, I was just lucky enough to be able to continually try to factory reset and then my phone randomly booted in to recovery (don't know why or how, it just did). After that, I flashed lockified TWRP and CM11 again.

Hey, My G Pro is on Miui and everything works fine on it. I can enter recovery mode and all that. But, I want to revert back to stock and this low battery error keeps popping upon during offline flashing. I have seen your method for bypassing it, but I have not found a solution. Is there anything else I can possibly do? Thanks!

This is what I did by accident
The problem, as I see it, is once you root your phone and put the custom recovery on it, CWM or TWRP, it overwrites your factory recovery. I tried using a 10k flashable zip I have to get my phone back to stock. BUT once I tried to get the OTA update to 10P, as another member here pointed out, My phone boot looped. So my question is, is there a way to remove the custom recovery and restore the stock recovery WITHOUT having to go through the PITA process of using flash tools? If there is a way it would save people countless hours fixing their phones just to get an update.
I know many of you don't see this as an issue because your whole point IS flashing new Roms. But from everything I have seen of this phone it's more trouble than it's worth. This phone is so very picky it's ridiculous. I just wnna get the damn 4.4 update, have it rooted to remove bloat, and call it a day. But to answer the OP question, you always have the option of buying a battery station online and charging your battery that way.
Fixed low battery error
My friend managed to fix the low battery error. He tested the method on my phone and during flashing the error did not show up. Will be creating a new thread which fixes the low battery warning soon. Stay tuned !
Sent from my LG-E988 using xda app-developers app
Nice work. And that thread will definitely help allot of others with that issue.
TL;DR
Aside from all the technical stuff, and since the g pro has a removable battery(thank god for that) there are several chargers that you can use which charge the battery outside of your phone. Here where i live (honduras) I have seen quite a few and had one myself(used it to charge spare batteries).
This morning my LG V500 offered a software update. I started the update process without thinking. When the tablet restarted to install the update I saw the LG logo and then was greeted with the following message on the screen:
Secure booting Error!
Cause : Device Unlock!, so Boot Success!!!
...after which I end up at the TWRP screen.
This happens every time I restart the tablet.
Before the update, I had Android 4.2.2 installed with kernel v3.4.0. I had installed TWRP v2.6.3.1 to root my phone. I have NO custom ROMs installed.
I'd prefer not to restart from scratch, but I guess that I can do a Factory Reset, Advanced Wipe or Format Data from TWRP to restore functionality to my tablet.
Any ideas on how I can avoid losing all my customizations?

What all have you tried?
A simple shut down and re-start possibly could fix it. Just a guess, but worth a try. You should update to TWRP's latest also.
same problem here
Same problem as original poster, just I was on 2.7.0.0 TWRP. Upgraded to 2.7.0.1 - same problem.
Restored from previous TWRP backup - same problem. Installed custom ROM - SAME PROBLEM!
Out of options at this point. HELP!

Ever since I rooted I've had that. In fact if you watch Ytube's video about rooting an LG G Tab, you will see guy say "Don't know what that is - but all works.
Now on a transformer101 I didn't see that.
But frankly, so what? You don't go to recovery that much -- that is the only time it shows.

I did a recovery with the LG tools. All my data was backed up so it wasn't a huge deal for me. I can't even remember why I rooted my GPad in the first place.

I Hope you worked things out, but your problem possibly could be that some Roms have a built-in recovery option - by that, I mean instead of just rebooting, they will boot into recovery. You might ck. that to see if it is enabled. This "SlimKat" ROM has the feature.
Good luck!

Cal-123, thanks, I was restoring backup done with TWRP - same problem (rebooting to TWRP screen, not to system). Still don't know root cause, but problem was resolved by flashing stock KK update by using B2CApp. Obviously root is gone, so back to reading forum
At least can play Deer Hunter again

Hi,
I want to flash my device to Android 4.4.4 Stock Android(Who likes this annoying LG Bloatware?).
When i wanted to get into Recovery Mode using TWRP the LG Logo pops up and in the top-right corner stands:
"secure booting error cause boot certification verify".
I tried everything i know to get into recovery mode, but nothing helped.
Go through the "first time" recovery manual installation procedure found in the CWM thread for the v500. I'm assuming you have a v500.
I have this problem too. Lg gpad 8.3 vk 810

Thanks a million, after hours trying every single method I found across the Web, this was the only thing that managed to get TWRP 2.8 on my v50020d 4.4.2.
It would be interesting though for us to let us know what exactly is that, because I found many people with the same problem than me, and this appears to be the only solution

Well, my problem it was I was using this method (the only one which do not gave me any explicit error) to install TWRP, and when rebooting to recovery it was always loading the stock recovery. That app solved me that instantaneously.
I was a little scared to see first the message "secure booting error, device unlock, so boot success" but it did loaded after TWRP. I guess that is supposed to be that way.
Yep @Maxxd01 That "secure booting error, device unlock, so boot success" it means it bypass ur bootloader to boot into custom recovery

Hello all,
I'm making this thread because i have an issue with my Recovery. Long story short:
I've successfully rooted my LG G3 D855. I've SU and rootacces. After this point i've used TWRP Manager to install TWRP. The application gave me a green sign that it installed successfully.
The problem at the moment is when i try to boot into recovery i can see this message: Secure Booting Error! Cause: boot certification verify.
After that the screen goes black and i can see a green and red LED flashing. The strange part is that i can still load in to download mode and i can use the phone normally.
I found a post by using google that use OneClick_Root_recovery but i'm not sure if i am safely use this since it will root the phone first(This has already been done).
I've also tried ImagePrePGUIv2.5 and chose the twrp only option. Sadly i still have the same problem.
Is there someone on XDA that have had this issue or someone that can help me resolve the problem?
Thank you for reading my post.
Have a nice day,
Thomas

which bootloader do you have?( on whick version did you root you phone 20x or 10x)
if you did it on 20x you need to flash the kitkat bootloader(there is a thread for that somewhere in lg g3 general )

Here is your answer
Pick your model and download AutoRec
Since you are just Rooting now i am assuming you are on Lollipop so this is perfect for you.
http://forum.xda-developers.com/lg-g3/general/apk-flash-twrp-autorec-thanks-to-t3081396
I want to thank you both because it's working !
This might be a newbie question but i'm a safe to install a rom now?
The reason i'm asking this question is because i totally forgot the bootloader when i started rooting and i'm wondering if i forgot something .

I have been running in circles on rooting my LG gpad 7.0 and with a lot of trial and error. With that said, I came across the error : boot certification verify. and that's it. Wont load or go further than that. I think I broke my device, any thoughts or help?

That's the error you get when you try to boot with an unsiged boot image. I've gotten out of that by using cybojenix openbump script to sign boot images (only works for kitkat bootloader), and using TWRP flash a ROM with a bumped boot image or just restoring a working backup. However, since you're just getting rooted I'm guessing you don't have TWRP installed (if you do, fixing this would be way easier).
If you're on the lollipop generation bootloader and don't have TWRP, the only option I can think of is to use the kitkat kdz to reset your tablet. It sounds like a really long and involved process to get the internal storage back to normal following using it. Good luck.
