Is this still possible? I'm running ZV8 on my LS990 and tried to flash ZV4 with the LG Flash Tool but it keeps erroring out. The error is "Model Information Check Fail". I've downloaded fresh copies of the files and used the below link. Still cannot ZV4 flashed from ZV8.

So after posting that I found the link below for a new root method. I did it and it worked. But now I cannot install TWRP. Is there a new process for installing TWRP on ZV8 rooted with the below method?

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

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 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.
I have an LG G3 VS985, I have rooted it using KingRoot online but I can't find a working recovery for it, all of them are invalid.
The only one I haven't tried is the one in this address:
downloads.codefi.re / thecubed / lg_g3 / bump / twrp-2.8.0.0_vs985-signed.img
That one is mostly recommended, I can access the site but when I do, it seems that my proxy blocks some ads and then I cannot access to the files. I can download any and I don't seem to find a valid alternative to those.
Can anyone hand me those files some other way, can even @thecubed try to help me with this please.
It'll be much appreciated.
Thanks
First of all, what version of the stock ROM are you rooted on? If it's anything above 12B (23C / 24B / 35B / 46A / 47A), then you can't install TWRP or any custom recovery very easily.
The best and easiest way is to downgrade to 10B (TOT method preferable but there's a 10B KDZ too), root using the Stump app that's on XDA, then use TWRP Manager from the Play Store to flash TWRP.
Then wipe Cache, Dalvik /ART and Data, flash @xdabbeb 's stock rooted 47A firmware and his 35B Bootstack.
Besides TWRP v3.0.0 that you can flash in TWRP Manager, @Dan11 makes unofficial newer versions.
Just Google for:
Code:
XDA Dan 11 G3 TWRP
But as I was saying, you can't flash TWRP from above 12B and have it work without a custom Bootstack.
I have the 47A version, but I didn't know there were a rooted 47A so I will try to downgrade to 10B using the TOT method and then follow your instructions.
I will update on any change, thanks for replying.

You're welcome! Happy flashing!
FYI flashing the TOT (or a KDZ in CSE mode, which is what should be chosen when downgrading) will wipe everything including your internal storage. You can use the built-in LG Backup to backup your user apps, user data and limited system data to your MicroSD card and then restore once you're back on rooted 47A.
Any way to return to Stock?
Yes I have tried the LgUp route....no go
Yes I have tried LG FlashTool route.......well something happened
Yes I have tried the ALL IN ONE Toolkit for Verizon......this is nothing more than the LG FlashTool route, just step by step.
History.......I flashed the new FW version 3.1.1 from XDABBEB and now I cannot flash stock again.
Best I could get is the LG FlashTool, because LGUP sees this phone now as "unkown".
When I try to flash through LG FlashTool I get null for pid and imei, yes I have used various versions of DLL that came with the TOT file.
At this point I am clueless......I can see that when I used the LG FlashTool it sees this:
Error: [14:53;5] CrossDL [VS985 4G] to [VS985]
Anybody have any ideas....thanks in advance.
i ran into the same problem also. i tried to flash back to 10b after installing @xdabbeb's 3.1.1 rom and i got the same CrossDL error almost immediately. the good news is that since the error comes up almost immediately, nothing is downloaded or flashed to your phone. you should still be able to boot into it.
i had a nandroid backup of my previous rom, which was jasmine 4.0. i flashed the 12b bootstack and then restored the nandroid. the interesting thing was that after restoring the nandroid, i still wasn't able to downgrade to 10b. i had to boot into the rom and then power back down. after that, i was able to flash 10b.
other people have reported being able to downgrade to 10b from 28a. @xdabbeb's 3.1.1 rom uses systemless root which modifies the system and/or boot image files. my guess is that the systemless root is what is preventing the downgrade to 10b from working. my suggestion is to try unrooting first and then try flashing 10b. if not, i hope you have a nandroid backup that you can restore and downgrade from.

The above, and flash any KDZ 35B or higher first, then the TOT since TOTs fix things that KDZs can't.
I attempted to root the LG V10 a few days ago. I managed to get the bootloader unlocked. I was on 20e when I did this. I then flashed 20L to get twrp and I can't boot up after that. It loops back to TWRP. Am I missing another part?. When I connect my phone to LGUP it says I'm still on 20e firmware. I will point out that in TWRP I get the error message that it cant mount /cache. Easy fix. Just wiping cache will do. And when I flash 20j zip, at the end it says that it failed or something but it wasnt in red. I haven't found a thread or youtube video that can help. I'm currently at work when writing this and I would like to be pointed in the right direction to get it solved when I get home. Thanks in advance to anyone who will help. :good:
Scratch that. I managed to get the phone up and running. I just flashed the 20j kdz and reflashed the rooted .tot
