I have one LG g3 Ls990 model with Android 5.0.1 and ZVA firmware.
I rooted phone with LG script method without any issue. Rooting successful.
After this I installed twrp with Ls990 autorec lolipop apk.
Then I switch off phone and booted in twrp and made backup of my efs and present stock rom.
But when I again booted phone , it show lg logo and screen written with "Security Error" and then switch off.
Still I am able to boot in twrp and download mode but not able to boot in rom.
Kindly guide me to resolve this issue.
Thanks in advance.

I don't know if this will help, but it SHOULDN'T hurt either.

Try flashing it. It's skin1980 sharpening mod, and it bumps the kernel.
Maybe it'll work.

I am in the same place (Security Error) and arrived there via the same steps. I think the only difference is that I am on ZVB firmware.
The firmware difference may explain (or maybe not) why I can boot into TWRP but NOT into download mode.
I'm thinking that if I have TWRP access I should be able to dig myself out of this hole, but not sure how to proceed. I'm guessing that doing a factory reset is not going to fix this, but if that were to return me to stock, that would be great. But I don't want to attempt that without getting some experienced feedback.
If a reset is a no-go, what are my flashing options?
Thanks for any suggestions!
Update & Additional Info: When I'm in TWRP, if I select Reboot and then Bootloader, the Firmware Update screen appears.

While you might be able to root ZV8, you can't install recovery from the OTA.
Flashtool back to zv4, root it, then install recovery. All of this is on zv4. Then you can flash Roms.

Darn, i kinda like how the ZV8 update is, plus i love the way CM is as well since the GS3 always had it installed. Does GPS work now with CM12 for the g3? Theres times where i need it and it never works. Ends up not locking my location.
All:
I have attempted to flash TWRP via various methods to no avail. I have somehow messed something up so I cannot get the stock recovery to work. I can get into the stock recovery screen, but if I select anything, it says Secure boot error. I am currently on OTA 5.0.1 VS98523C. Any advice on how to proceed? I have looked at KDZ options, but am wondering if I can just get the stock recovery back and let it ride until TWRP is available.
Thanks in advance,
Steven
I'm having trouble with getting TWRP to flash successfully. Using their app and flashify

In theory, you can use the dd comment to put the aboot back, but I would not recommend it as I got my phone hard bricked that way. (so dead that even KDZ does not work)The safest way is KDZ back to 10b, and then stump root. Then:
1. Install TWRP manager from Google Play.
2. From TWRP manager you can choose your phone model and download and install TWRP recovery.
3. Follow the instruction from this link to use TWRP to install the 23c

Never do OTA if you have rooted your phone. It needs to be completely stock for OTA to work.
/\ What he said.
Twrp doesn't work after lollipop because of the signing requirements in the bootloader.
It needs to be rolled back to 10-12b and then rooted and then you can load twrp. Once you have twrp you can load jasmine or skydragon which are both 5.01.
http://forum.xda-developers.com/verizon-lg-g3/general/guide-flash-to-stock-10b-kdz-method-t2928140
Thanks! So if I want to use xposed, I should roll back to the other versions of lollipop?
thanks all. I KDZ'd 12b stock rom, rooted, then flashed TWRP through flashify. I then went into recovery and installed the 23c rom. I used skydragon 4.0.0 because I tried to flash Jasmine 7.0 like 8 times. I did not have any of the bottom keys and I could not access my pulldown menu. I could not figure out why this was happening. Skydragon worked for me perfectly. Thanks All.
I came from cm13 and i suddenly think of returning back to stock lollipop. After a few days, I realize cm13 is a lot better. I downgraded back to kitkat and unlocked the bootloader the way I did before. Before, it was successful. But now, when I flash TWRP and reboot to recovery using flashify, it shows security boot error. I upgraded to stock lollipop and tried it unlocking bootloader there. I flashed TWRP but when I entered TWRP, I cannot reboot back to system. I cannot get out of recovery!! Pleasee help... I want to get cm13 back

you should write this in other section but i want to help you.
maybe try to flash stock kdz again if you still can then check if bootloader method you use is correct but if was not you will brick your phone.

u even can flash kdz ? if yes, try it and check if your bootloader unclocking method, file, is correct.
You could brick your phone.
I did a data wipe accidentally in TwRP. Meant to just get cache. Now I lost root/TWRP apparently. Just recently updated to 20c. I have no recovery when I reboot but I still get the unlocked bootloader info when rebooting. Any ideas/help is greatly appreciated.

I don't see how wiping data would remove TWRP, but the way I'd reestablish TWRP once it's gone would be to LGUP the Tungkick 10d tot file and then use that TWRP to flash the 20c zip by Autoprime. Flash SuperSU one way or another and then have a blast. I'm sure there are other ways to accomplish all this, but this way is easy and has been reliable for me.
It seems that you can still boot the phone.
If you still have valid bootloader the issue is not that tricky.
Just do a "adb reboot bootloader" and reflash twrp, like how you installed them in the first place.
I'm not sure which exact version of twrp is compatible with v20*, but that should be easy to find anyway.
Then boot into twrp and flash supersu/magisk/any other thing you need.

So I did a factory reset from the settings menu. Now it boots back into TWRP. Weird. But that's it. No OS. Just the recovery. So I guess I'll try and flash a ROM and see if I can get that back. Thanks for trying to help.

Wasn't sure if I could do any 10s coming from 20C. I got into TWRP recovery but now I have no OS. Thanks for helping out.

Yeah, as long as the ARB is the same (ANTIROLLBACK 01) you can flash 10 after 20. I don't think 10a qualifies, but 10d should be okay from 20a or 20c.
It's a quirk of the G5 that TWRP can only be accessed from boot by factory reset of the phone. If you are already up and rooted, you can use a command or program AFTER boot to access TWRP without factory reset. But, for now, that's our doorway into TWRP from power-off.
Now that you're in TWRP you can sideload a ROM onto your SD and flash it, just remember to also flash the latest superSU zip afterward to ensure root (unless your ROM is pre-rooted.)
