I have a Verizon LG G3 and wanted to root to change the ROM. I used kingroot to root and then was able to add superuser, root checkers showed I had root and superuser access. I read online a few people were able to use flashify to put Twrp on their device. I selected the VS985 and after it was done it would not boot into recovery. The phone loads and runs fine but now ot shows the phone does not have root, superuser says it needs update and fails, and I cannot even do a factory reset.
How do I fix the recovery so I can either finish the root and recovery installation, or just go back to stock?
Thanks!
Phone is on Marshmallow. Guides I found to fix say you need to be on lollipop. Phone boots right now, so I do not want to risk trying too much since it boots now.
Fixed it using lg flashtool but with this dll file http://forum.xda-developers.com/show...4&postcount=84

[Q] Problems w/ Root & Custom Recovery on LG LS980...and I only have Ubuntu access...
First off I'm running Ubuntu 14.04 and I'm probably not as tech savvy as I should be for someone running Ubuntu. I do not have access to a Windows computer. My gf has a Macbook Air but I know she's tired of me running my phone experiments on it. Here's the problem that I'm in. I have spent hours upon hours of research and made numerous attempts at this and I just can't figure it out. I have an LG LS980 and I'm running the ZVE update (phone already had ZVE on it when I bought it). I do not have root or CWM or TWRP. I have been trying to root, install CWM or TWRP and then switch to CM 11. I originally rooted my phone, then, because of an incessant error issue (it would pop up repeatedly every second making the phone unusable) I had to factory reset. Since that factory reset I have not been able to achieve root. I have tried everything (IOROOT, STUMP, TOWELROOT) nothing. Stump says that I'm rooted but SUPERSU says I have no binary. I figured I'd just go straight to a custom recovery and then flash a rom that is already rooted. However it appears that there is no TWRP or CWM for LG LS980 without root. I just can't figure out how to get root status back and how to install a custom recovery. I'm stuck and I need help. I've read about going back to a stock ZVC and starting all over again but I don't know how to do that. I appreciate any future help from you all.
Using LG Flash Tool, you can tot back to stock, and retry rooting. There are a couple of guides floating around here, I'd look for one of them and just follow it exactly to get root and TWRP set up, then you can try your hand at a custom ROM.
Edit- Not sure if LG Flash Tool works on Ubuntu. If it doesn't or you just want to play it safe, I'd borrow a friend's laptop to run it. It's pretty quick, like 5-10 mins if I remember correctly.
Yes I have read that but does anyone know how to do that on Ubuntu?
Please don't refer me to any more threads or forums........
I'm sure this has been done and done and talked about but I've been reading the **** out of forums and comments for a few hours now and trying to unroot my Sprint LG G2.
I had it running stock like a champ. rooted it. worked great. then I was attempting to flash lollipop and it required a recovery update (No Problem) I downloaded the correct files and bam! it says your phone is not rooted this requires a root (or something like that) I was already rooted SuperSU installed and root checker said I was fine. so what the hell I swipe to root while inside recovery and it goes to some black screen with tiny text saying fastboot: processing commands and won't leave the screen. I tried booting into recovery and same thing happens. Tried to reboot normal and I'm stuck on the LG logo with my led flashing between blue and green slowly. I CAN boot into download mode and I'm following this

Please help!
When i'm in download mode the phone does say I am rooted. is there a way to just re-flash recovery and restore from my backups I did before all this? if I have to wipe this thing clean and start over I don't really mind I just need to get my phone back haha this is the first time this has ever happened to me and I consider myself tech savvy so idk what I did here (except re rooting in recovery like an idiot) thanks so much!
First question, is the download mode you see with a small status bar or the big one?
If you have the big one, download mode should work. The f flash software will verify the tot file. If that goes through you should be golden.
When it asked you in TWRP to root, that is a message telling you system or ROM file did not take.
If you want cm12, use zv8 tot. Root, auto-rec, update TWRP with blastgator bumped TWRP 2.5.1. Flash cm ROM or aosp, then gapps. And go
I'm having issues with a LG Optimus G. I can't access Recovery or Bootloader. I can't even root it. When I use Root Checker, it says something it's wrong with the actual root.
All I wanna do, it's to install a custom ROM. But that seems impossible since I can't even get into recovery. I installed a KDZ but even then it won't work.
Download Mode, seems to be working. I tried rooting with the bat file, but nothing, it won't work!
I followed the Unbrick Tutorial, but nothing.
Any ideas?
Thanks
I used this Root on E975 with Stock 4.4.2 and it worked.
There is also a detailed description how to do it right.
You can unlock the Bootloader with FreeGee after you've rooted the device.
Then i would recommend you flash TRWP 2.8.7.0
P.s.
But you also can try towelroot or maybe King Root but i suggest the first Methode.
Thanks! King Root did work! Now it's rooted, still I can't install recovery I tried with FreeGee but it won't work it says "Perfoming action" for about an hour. Also tried with Rom Mananger but nothing.. it won't install it.
I keep getting the error "Secure Booting Error! Cause : boot certification verify" each time I tried to boot into recovery.
Maybe re-flash the last original KDZ file for your device first and then do the common steps -> Root -> Unlock Bootloader -> Flash Custom Recovery
You can Boot into download mode by "Hold VolUp + VolDn and put in the Charger cable connected with your Computer"
Then you can try the Original LG Software to "Reset" the device or use the LG Flash Tool 2014 to offline Flash a KDZ file.
KDZ for you device you can get here or use the Original LG Firmware tool to download for your device.
Get Sure you backup all the data you need before, becasue this Method will "clean" your device completly!
Edit:
Get sure you use the last USB Drivers, i've used the LGMobileDriver_WHQL_Ver_4.0.4.exe
Hello
I tried rooting my LG H815 and it didn't go so well.
I managed to successfully unlock the bootloader following the steps on the LG developer website.
I downloaded SuperSu (UPDATE-SuperSU-v2.46.zip) and placed it in the internal storage of the phone.
Afterwards in order to root the device, I booted into TWRP with "fastboot boot twrp-3.0.2-1-h815.img".
In TWRP I flashed SuperSu. After it finished flashing I rebooted the device. After it attempted to start up again, it froze at the LG logo. I waited around 10 minutes and figured it's not successfully boot.
I removed the battery and tried to fire it up again, but it didn't get past the Logo screen again.
I managed to send "adb reboot recovery" to it, but all I get is an image of a little dead android. I guess this is because I only booted TWRP and did not flash it.
When I get it in fastboot mode, "fastboot boot twrp-3.0.2-1-h815.img" does work anymore now. I just says < waiting for any device >.
I managed to get into default recovery with power up + vol down where it prompted me to do a reset by responding Yes twice, but after it rebooted, it still got stuck on Lg logo.
If you cannot get to the recovery then follow these steps:
i) Make sure you have the LG Drivers installed from here: http://oceanhost.eu/e4h2px4e0hkd/LGMobileDriver_WHQL_Ver_4.0.4.exe.htm
ii) Download the LG Bridge software from here: http://www.lg.com/us/support/product-help/CT10000025-1438110404543-preinstall-apps
iii) Remove the battery and reinsert it so the device it is fully off.
iv) While holding the up volume button, insert your USB cable.
v) You should enter download mode. Go to the Software Update tab of the LG Bridge. It will say connecting and then should say your device is up to date. Click on the recovery text on the bottom right and then follow the instructions. The software will download the system image for you and this is roughly 1.6GB so make sure your firewall doesn't block this connection.
This shouldn't delete your data (no guarantees) but you will have to grant app permissions again and reapply any changes to system files e.g. root, viper4android, xposed ect.
If you have problems try this method instead:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
If successful and you're brave enough to try again. Then make sure you actually flash TWRP. I think you are right in that you only booted TWRP .
You can follow my TWRP/root guide here: https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
Good luck
Thanks a lot for answering.
LG Bridge wasn't detecting my device. I don't remember if I was in download mode when I tried this, though. I might've not been.
I didn't know how to fix it and asked a friend for help. He managed to flash the h815 stock firmware through some Taiwanese/Korean flash tool (Edit: It was LGUP and he flash a kdz file with the stock firmware).
I followed a similar guide to yours when I flashed SuperSU from TWRP, except I didn't install twrp permanently after booting it from the .img file. I thought it was not possible to install twrp if the device is not rooted first.
I still kinda want to root the device since I voided my warranty by unlocking the bootloader, but I'm afraid I'll break it again if I use the same method.
Edit: Managed to successfully flash twrp. Booted into recovery again after rebooting system. I am now creating and saving a full backup with TWRP. Will try flashing SU again afterwards.
Edit2: I flashed SU after properly installing TWRP and it worked like a charm.
So, long story short, I followed this tutorial: www . htcmania. com/showthread.php?t=1024045 (remove the spaces in w.h and .com) and it didn't go very well.
I flashed TWRP and SuperSU as told, using both download links (TWRP 2.8.7 & SuperSU 2.46), and my phone got stuck in a bootloop at LG bootloader unlocked logo. I recovered my phone by using LG Bridge and after that, when i tried to enter TWRP using the phone keys, it resulted in a factory data reset (no TWRP after recovery, didn't know that). I then followed the exact same steps but using what I thought was the lastest SuperSU archive (SR5-SuperSU-v2.82), flashed the archive and when finished, TWRP asked me to flash it again (so I did), then rebooted, passed LG bootloader unlocked logo, got into LG animation and... Bootloop again, so I recovered again with LG Bridge but I din't attempted to enter TWRP because this time i knew it wouldn't work and I ended it there, reinstalling all apps and configuring my phone as I had it before my unsuccessfull attempt. I continued using my phone as usual but sometimes, when I enter Pokemon Go, it says that it couldn't log in and that my phone's OS is not supported. As I said, the app does this sometimes whenever it wants, so I researched a bit and turns out it doesn't work with rooted android devices (I didn't know that). I knew my root attempt failed so I downloaded and app called Root Checker and checked: Root status-Not rooted; SafetyNet Status-Failed. I don't know what should I do know, last time I rooted my phone was a Sony Xperia XL and it wasn't so tricky.
I asked for advice in the forum and got no answer, so here I am, hoping for a solution. What I want is to have a permanent custom recovery, a rooted device and to have SafetyNet status passed. Any ideas, hints or whatever? Please, help
