so i downgraded to v30 of mm to be able to root my G3. I used lg toolkit 2014 and flashed it correctly that way. once I did I installed kingroot and rooted. after that I flashed or tried to flash twrp using flashify and official twrp app. they both say successful but when i go to go into recovery I get a error;
"boot verification fail!cause MISMATCH_SIG_LEN"
then it flashes red/blue. phone is still fully functional after and still able to use it. (no brick or anything).im not sure what else to do any suggestions?
thanks

I was able to root my device using these instructions
http://forum.xda-developers.com/showthread.php?t=2401901
I can confirm that it is rooted, TWR is loaded as the recovery and superSU is running as well as some root-only apps.
The problem is that no matter what or how I try, I cannot get a new kernel to install nor can I flash a ROM.
If I try to do either via Odin it completes without errors (either on the computer or tablet) but when the tablet is rebooted, no changes.
If I try to flash a rom from the recovery it just errors out and fails
I even tried using Odin to unroot and reset back to stock and that worked but when I re-rooted it again I was back to where I'm stuck!
Has anyone ever seen this before?

1), If you used the TWRP from that post, then you need to update to a newer recovery. TWRP for KK
2). Telling us that "it errors out" is pointless. You need to tell us exactly what error you are getting.
3). Attach the recovery.log from the failed attempt to flash a rom. Google can tell you how to get the log.
welp, I feel dumb - it was the wrong version of TWRP that was causing the problem all along
N00b needing some help. It seems I have corrupted the recovery on my rooted G3 VS985. Used TWRP Manager to flash TWRP. Followed the app's instructions, installed BusyBox, applied the KitKat/Lollipop patch, went ahead and flashed. Booting into recovery just gives me a black screen and blinking blue and red LEDs. Since I'm not an expert, I'm a little paranoid to continue.
If I use bump to flash TWRP, will that wipe the corrupted file and flash a working version of TWRP (assuming I don't eff it up)? I've also seen root methods for the G3 that install TWRP as well. If I unroot and reroot with one of those methods with a bum recovery, will I brick my device? Sorry for the n00b questions, and I appreciate the help!
Look at here forum.xda-developers.com/lg-g3/general/apk-flash-twrp-autorec-thanks-to-t3081396
I have d851, looking for another alternate solution for the corrupted recovery. please help.
Same issue
Same question here also. Updated twrp from twrp manager playstore app now when i enter recovery i get black screen and boot security error. Other than that i can go to download mode easily and can boot my device to android cloudy g3 without a hitch the only problem is that i can no longer use recovery
ok so I have a vs985 that was rooted with twrp and was running stock 4.4.2 10b. Ive been on it for a while and wanted to update. went though my usually backup routine, then updated base band to 23c installed cyanogenmod 12.1 then went to install gapps but when it started it rebooted back in to twrp so I tried again with no luck same thing, so I figured I'd boot the phone and go out and grab a new download reboot into recovery and install gapps, but after rebooting wasn't able to boot back into twrp. for some reason the button combination wouldn't work nor an apps I downloaded from the browser as I didn't have play store. either way I was able to get into something that allowed for a safe mode and reboot but that was all. so I said ok I use recovery tool to flash 10b root then install twrp then same as before update modem, cyanogenmod then gapps, but after going back to 10b I was not able to get root using stump root as I had before. every time I tried loading the app and I got an error saying something about phasing and everything I tried I was able to get it to load. so I thought maybe I could run some updates and try and root from other methods and so far no luck. so I'm currently on 5.0.1 and still cant root this methods like lg one click root so others. any ideas why this is happening? I don't mind going back to 4.4.2 10b to get root but I've had no luck with the multiply stump root or others I've tried.
thanks

Hello everyone, so today I was playing around with Flashfire by @Chainfire and even though the app says it's untested for LG devices I decided to try it out on my LS980 LG G2, I restored my stock ZVH Recovery through AutoRec and went into Flashfire app and proceeded to make a backup of my stock ZVH Recovery, afterwards I loaded up AutoRec and reflashed twrp, then I used Flashfire to flash @blastagator's latest twrp 2.8.7.1 bumped recovery through the flash zip function, all functions worked perfectly, the attached zip is the result of the backup I made with Flashfire
EDIT: This backup can only be restored using Flashfire app.

I'm a little confused. Maybe you can help. My gf's Sprint LS980 is currently rooted on ZVG. I can (and will) install TWRP via AutoRec, as I just did with my LG G3 (LS990). However, my goal is to get ZVH installed on the LS980, maintain (or renew) root and not have to wipe or lose data. Will your method allow me to accomplish this? I'm not familiar with Flashfire, but will certainly install and use, if it gets me where I need to go.
One final question... I saw the next post mentioned ZVG*, making me wonder if your recovery was ZVG, not ZVH. Would appreciate any clarification and additional instruction you can provide to assist me. Thanks in advance!
The recovery in question is the one I backed up on ZVH which I'm currently running right now, but as far as I know it's still the zvg Recovery, I labeled it ZVH cause that's currently what my phone is running and when I made the backup, but to answer your question, I would backup your data partition, copy your backup to your computer or external flash drive for safe keeping then tot back to stock zve, download and install the 2 otas afterwards, then root the phone with your preferred method, install twrp through AutoRec, then flash @blastagator's twrp 2.8.7.1 bumped Recovery, then boot into twrp and restore your data and you should be all set

Hi guys it's been a while since I've rooted any devices but decided to root my LG G PAD 8.3 (V500), since it is so outdated. I'm gonna go over exactly what I did on how I got here to better understand. Sorry in advance for the long winded post.
-Anyway, I had to downgrade to 4.2.2 by using the LG Flash Tool 2014.
-Then, I rooted my device by running root.bat Also, I had SuperSU when I rooted.
-After rooting, I installed TWRP via the play store, downloaded the most recent twrp.img and flashed it via the app. It took me forever to get to recovery by pressing power+volume down and then pressing power+volume down+volume up. But after what felt like 20+ tries, I got to TWRP recovery.
-I wiped my phone and flashed the most recent Lineage ROM. Unfortunately, after flashing the ROM, I could not flash GApps because it rebooted to the ROM after flashing. TWRP let me know that I had to update TWRP and since I did not have the play store and I was once again having trouble getting into recovery, I downloaded the most recent TWRP apk.
-When trying to open the apk, it gave me a "can't open file" message which I didn't understand why. After rebooting, for some reason, it then let me run the TWRP apk and installed the TWRP app. This is when I found out that I was no longer rooted because TWRP notified me. I double checked with root checker and indeed I was no longer rooted. I have no idea when or how that happened.
-Again, I couldn't get into TWRP recovery until I plugged in my phone to my PC and for whatever reason, it helped me get into recovery. I wiped the phone and proceeded to flash Lineage and GApps.
-I read that by flashing SuperSu I may regain root, so downloaded an updated SuperSu, went into recovery and flashed SuperSu. When rebooting, the LG screen came up with a message at the top left corner reading "secure booting error! Boot certification verify". At that point, I was in a bootloop and had to go into recovery, wipe and flash again minus supersu. So I am now on Lineage with GApps and no root.
How do I regain root? And anyone know how I was able to lose it? Back in the day when I was into flashing, I never had these problems and never lost root out of nowhere like this.
Also, if I wanted to get back to stock LG 4.2.2, how would I go about that? I know that currently, I can't use the LG Flash Tool 2014 because my current ROM does not have a USB Software option in order for the tool to recognize the tablet.
Any help would be greatly appreciated, thank you.
