Last night I have two LG vs985 in marshmallow 6.0 firmware have some issues of wifi and System UI fail. So I decided to downgrade it to 10B firmware
First I use one phone and downgrade it by LG UP and then It was reboot to recovery and showing the installing process in recovery after that it restart and doing the same process. I think this phone have some hardware issue
So I flash another one and it was doing the same issue
I downgraded many VS985 with this method but now this two phones have a issue after downgrading
I also try LG flash tool and it was also successfully flash the phone but after that same issue
I Wiped My Data In Recovery Mode And That Helped

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.

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.
Was running total stock with stock recovery (Unlocked BL tho). Latest update (attached) flashed without a hitch and upon boot, hangs on the Motorola logo. Anybobdy else experience this?
UPDATE:
Restored previous system and boot image and it booted without issue. Said the update was complete upon boot despite being the old system. Then, almost immediately tried to re-update (which i assume would brick it due to it already having the new bootloader). Look forward to feedback cuz this got me bummed.
You can't take ota updates if you updated the Bootloader past 5.1 Bootloader. So if you want to run the latest firmware but keep stock flash a custom stock ROM. Or better just flash cm12.1

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.
Hi,
I have a rooted LG G5 H850 with an unlocked bootloader and TWRP. I was on H850 20A OPEN EU ROM from autoprime and I tried to flash H850 20D OPEN EU ROM. I booted into recovery TWRP and flashed the Zip file together with the newest SuperSU. When I tried to reboot the phone stuck in reboot - always changing between the message "Your device software cannot be checked for corruption" and the LG logo. After a long time (15 minutes or so) I pulled the battery. The same thing. Then I tried to get into recovery using the 2 hands method. I clicked through the factory reset screens (yes, yes...) - and the phone stuck between warning screen and logo again.
Could someone help me to get into TWRP again? If this would be possible I could restore my backup. Otherwise I don't what to to else...
Thanks for any helP!
Ok, after several tries with the 2 hand method, I got into TWRP again. I tried to restore my backup but it failed with an error. After that I did a full wipe (factory reset) but without the internal storage. Then I flashed the 20D zip again, after that SuperSU. Now the phone is rebooting and rebooting and rebooting. It is stuck on the LG logo and nothing else is happening. It's frustrating...
Firmware reset > flash zip file.
If that doesn't work use the LGUP or LG Bridge method to flash firmware. There should be threads in the development section

Thanks for your help, but I don't use windows. But in the meantime I got it solved. The reason for the failure was a corrupted external sd card. Flashing from a new card did help.
i'm getting the same problem with the OREO OPEN EU ROM, booted into TWRP, flashed SuperSU and after a few loops got stuck on the LG logo. Had to pull the battery, go into download mode & reflash the ROM via LGUP. I somehow doubt it's the SD card as there were no errors on the SuperSU install.
Guys i need help few days ago my LG V30+ L-01k was bricked then i visit a shop he flashed h930ds oreo with qualcomm box when i came home i flashed h93020d kdz as Partition DL then unlock it flash twrp then i flash stock L-01k zip using twrp but my phone stuck in boot animation i tried RR oreo rom but it also stuck in boot animation i tried h93020d as refurbish mode didn't worked so can someone help me how to get rid of this ?
