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?

Hello guys,
I need your help. I have a L7 II P710 and have intalled the rootable KDZ version months ago, but now I installed an OTA update accidentally and stucks since in the recovery (twrp). I checked all threads for a solution and tried to flash the new P710 V20C EUROPE OPEN version to repair the problem, but with several methods from the LG Flash Tool 2014 I could not solve the problem and still stuck in the recovery. Now I could need support from experts like you!
It would be glad when someone could assist me in this problem.

If you have working TWRP, try to flash some of custom roms' like CM10.2 first. After that (if your device boot normaly), you may flash stock kk europe open.
And more details please, like version before ota upgrade, your country, simlock status etc.

Thanks for your reply. I could solve the problem... I downloaded a stock kdz version that doesnt include the twrp recovery or something else. After that I could boot normally up and down. Then I flashed the new rootable that includes TWRP and all works fine. But now there is a OTA update again and I would like to apply this update, but with the TWRP recovery it is not possible. Is there any way to restore the stock recovery without flash a stock rom?
My kdz contains pached bootloader (APPSSBL), and after upgrade via ota you have brick.
If you want this upgrade (why if you can flash my v20c?), you must flash back original RECOVERY and APPSSBL, extracted from your present original rom kdz.
And unroot your device.
Or you may simply flash original kdz.
After ota upgrade, no longer root is possible.
I flashed your 20c version (this was meant with "the new rootable [rom] that includes TWRP"), but my smartphone shows me every time the possibilty to update. Actually i don't need this update and tried to deactivate the OTA updater. I deactivated the update manager from my lg and disabled the notification but it still shows me the message to update. Could I backup the app via TitaniumBackup and delete it?

Yes, good idea. I recommend you to backup whole rom with TWRP. Just disable screen timeout in TWRP before performing backup.
Actually there is a solution. Its better not to use FOTA update if u have custom recovery.But also attached file can help.Sometimes.Helped me with v20D updates. Just flash it via recovery.

Hi guys,
just received the v20c-SEP-09-2016 update on my 960A in Europe. When I click "install now" the device will prepare the update an boot into TWRP. No installation is done. Is there a way to manually install the dlpkgfile, that is located in /cache/fota/ ?
Will my device still be rooted after the installation?
I already renamed the dlpkgfile into dlpkgfile.zip and tried to flash it through twrp, but the zip-integrity-check failed and I dare not to flash it without :-/

We need a flashable zip. Can someone provide please?
You can just flash the latest kdz file from LG and root the phone again : http://forum.xda-developers.com/showpost.php?p=68414181&postcount=83
Will it wipe?
Hi,
no, it will not wipe your phone if you select the "UPGRADE" Option in LGUP. Did this twice myself for V20b and V20c. You have to install TWRP and SuperSU afterwards again.
Ah, thnx. Is it worthwhile doing such mini upgrades?
i was trying to flash the rooted tot with LGUP i try refurbish and upgrade none of the work please help me
Flash official kdz, select update. That will get you out. Or you can flash Andy's rom on twrp

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.
