Lost root, can not seem to get it back - LG V20 Questions & Answers

Magisk show I have root, and it is installed correctly. I wiped system and reinstalled, still no app shoes I have root. The bootloader shows it is unlocked and TWRP works, but ever application says root is not installed, tried to install magisk manually from TWRP, no issues, but still all apps say I do not have root. What can be done, I can not afford to not backup, so a clean re-install is an issue since Ti-Backup does not show root access.
I would assume manually flashing magisk would fix any issue as would wiping and re-installing system, but neither resolved the lack of root issue. This is on RR Remix so it is rooted by default.
Please help,
ERIC

Did you make sure Root is checked in the Developer options?

Found the solution, with magisk there is a settings option to enable root for Apps or just ADB or both, somehow it got switched to ADB only.

root broken on CM12.1

Hi,
flashed my nexus 4 to CM12.1 successfully. For some period everything was fine, even root access. Since an unknown point in time root access does no longer work, even though dev settings are activated and enabled and root access is set to "adb and apps". There is no "#" sign any more in the info section and all apps (Titanium Backup, TWRP Manager, ES File Explorer, ...) fail to get root access. What can I do to repair it? Can I do a dirty reflash (without wiping) to keep apps and re-gain root?
It might be possible that I caused that with the deinstall and removal of the supersu app, as I realized to late that this app is not required with CM12.1.
Thx,
Robert
I tried the dirty reflash of the 12.1 zip and it worked. Apps and data still there, root is back working.

PHH's Root Disappeared

Hi Guys.
As the title suggests root access suddenly disappeared from my nexus 6p yesterday.
DigitalHigh rom 7.0 was flashed through the latest twrp (3.0.2-2) and everything was running fine. I got the notification that the SU binary is out of date from PHH's SuperUser. Opened it but nothing really happened. So I downloaded superSU and suddenly it prompted me that the device isn't rooted. Being unfamiliar with PHH's SU I decided to flash the latest SuperSu through TWRP but the phone wouldn't boot.
Right now it has been restored to a backup taken just before flashing SuperSU which means everything is running fine and even android pay works however there's no root access. Is there something specific that might have caused this?
Are there any ways to re-gain root?
Haven't gone through the process of a clean flash yet as the phone is needed for work however even if all of that is done the SU binary will still need to be updated. Is there a different method for updating PHH's root?
So far I have tried clearing cache etc. but noting worked.

Phhusson's superuser and SuperSU don't mix. If you're back to booted, but not rooted with Phh, you'll need to either flash one of the Nougat boot images from the nexus/angler folder or the latest superuser.zip (I think the latest is r229) from http://superuser.phh.me

[Q] Magisk Root

Has anyone been able to get magisk to work appropriately? I attempted and the magisk apk kept fc'ing. I read about LG devices needing a boot.img "bump". Is this true or has anyone got it working in their own way?
There Is no root method for variants that don't have a unlocked bootloader. You would know this if you read the forums before asking

So, quite frankly, if you read, another user has it working. Further more, with the TMO variant, I do have an unlocked bootloader. Root application works with magisk, however the APK itself fc's.
I thought cowboys were polite ; )
I misread your post thought you were the typical person asking for a update on root I apologize.

I have the H918/tmo and I was able to get magisk running with phh's superuser. I'm kinda iffy on magisk-hide, as i had issues with it initially ( random reboots with it enabled). I turned off magisk hide for about a week, then turned it back on last night with no reboots since.. but haven't tested it with apps.
After running the easy recowvery + root script, i got rid of SuperSU. I believe all i did was a Full Unroot in the options, with no changes to the recovery. (I also may have done a format /data when rebooting to recovery again, but i dont recall fully, so take that into consideration if it didnt work at first (followed by the no-verity-opt-encrypt zip).)
After getting rid of SuperSU/su binary, what i remember doing was:
1 ) Flash magisk v9.zip -> reboot to system to make sure it boots, then adb reboot recovery.
2 ) Flash phh's superuser r266-2.zip -> reboot to system
3 ) install magisk manager via apk, and phh's superuser via playstore.
4 ) test out root.
has anyone been able to get Phh's superuser to work on the Sprint v20 / LS997 ?? If so, how? Thanks in advance.
If you can't get this working there is an app called RootSwitch. It can successfully hide root on the V20 with a toggle.

ive got 1 working and 1 in testing that uses magisk and phh.
the phh superuser seems to be casusing the systemui to force close often when in hide mode and the random reboots and loss of service, otherwise it was working fine.
but yeah, just flash version 10.2 on your current rom and see what happens!
btw this was on DEC sec patch, on oct builds i never tried it, but this is latest DEC sofware, didnt even use rootswitch

Tried RootSwitch w/ SuperSU. Didn't pass SafetyNet if that's what you were referring to.
Tried it again last night. Had the 1st 3 options turned on. Soon as I opened Android Pay my phone hot booted and got stuck on the VZW splash screen. Had to pull the battery. Won't try that again with supersu.
I have a VS995 this is how I got my phone to finally take magisk and pass the safetynet check. I'm running software version VS99513A I performed dirty santa to get unlocked bootloader and root access. Now I tried to uninstall supersu threw the app and I got a failed message. I tried going into recovery and flashing the supersu unistaller and that would fail. I tried flash magisk v12.0 and keep getting error message. I got stock in twrp recovery several times and used LGUP and flash either VS99512A KDZ or the VS99513A KDZ. Am not a developer but it seemed as if the boot.img won't take by the magisk zip. Those where my failed attempts for about a week or two. Now on to the success story
Performed Dirty Santa on software version VS99513A. I decide to flash modstock kernaI update v1.1 because it seem to work well with a stock rooted VS995. I flashed busy box in recovery and downloaded the app and also downloaded quick reboot so I could reboot into recovery easier. After reading @poixninja thread on modstock kernal - stocked with goodies he mention flash a boot.img that was patched with magisk. So I but the phone into fastboot mode and flashed his boot.img onto the phone with cmd (command prompt). I think I might have tried to uninstall supersu threw the app and I think it didn't work after flash the boot.img. So I put the phone into recovery mode the to wipe and then to advance wipe and clear dalvik and cache. After that I went to install and flashed the supersu unistaller and it took. After flashing I wipe the cache that twrp ask after most flashes. I then rebooted into recovery to make sure my twrp was not affected because I had and issue with that in previous supersu unistaller attempts. Rebooted ito twrp recovery then rebooted into system. I think whenever I flashed the verzion logo stayed up longer than normal but the phone fully started up. I clicked on supersu and it said no root access. Turned of the phone and did the steps to get to recovery mode. Once in I first wiped dalvik and cache. Then I flashed magisk unistaller and it went threw with no issue. I wiped dalvik and cache then rebooted into recovery. After getting into recovery I rebooted to system.
Sidenote: I recommend after wiping supersu and flashing magisk unistaller. Once you boot up install magisk apk. I didn't install the apk until after I flashed the magisk v12.0 in recovery. I noticed when I reboot the magisk icon was on the phone but when I clicked it it said go to playstore to download. I had the magisk manager apk on my SD card so I just installed it. The install to longer than normal I think it was because I didn't install it prior to flash the zip in recovery. I didn't get a chance to verify it yet.
Once the phone boot and I installed the magisk app manager I open it up and got green checks for installed magisk v12 and properly rooted. I went to setting and turned on enable busy box, magisk hide, and systemless. But when I clicked safetynet I got cts mismatch. Did some research and read on other XDA magisk thread that it maybe because of custom roms, modified kernals and possible supersu somewhere on the system. The only root accessible apps I had installed during this process was busybox and quick reboot. I did notice the first time I ran quick reboot after getting magisk it did give it root access then it did after I opened it again.
I decide to uninstall quick reboot and busy box. I uninstalled both apps. I rebooted into recovery mode the manual way. First thing I did was wipe dalvik and cache. Then I flashed busy box uninstaller. When the flash was running I say in the command lines that it found supersu. Which I thought was odd so I also flashed supersu unistaller. I rebooted into recovery wipe dalvik and cache and flashed uninstall magisk. Then reboot into recovery. I ran busy box uninstaller one more time to see if it would pick up supersu again and the command lines did not mention it. I flashed back magisk v12.0 rebooted into recovery. Then rebooted into system
Opened magisk went to setting to turn on enable busy box, magisk hide and systemless. Check safetnet and failed I found a magisk XDA thread that talks about common issue. It said I had to check magisk core only mode. Once I did that he requested a reboot which I did. Once back up I first cleared in app manager under show system I cleared all data for google play store, google play service for instant app, google play services. I opened magisk clicked safetynet check and I passed it. I went to search for netflix in play store and it pop up I installed it and it working fine so far. I tried logging into snapchat and I got threw.
Hope this maybe help full to anyone having issues

If I may be so bold, I played around with the rooting process on mine (I have a VS995 on 13A, too), and found a much easier (and possibly cleaner?) way to do this. Of course, the way I'm about to suggest would require a full KDZ to stock and a factory reset...
Here's mine:
Follow this thread:
https://forum.xda-developers.com/v20/how-to/lgv20-vs995-verizon-aio-post-06-19-2017-t3624326
Note: For noobs: After step 13, it's a bit misleading, because it doesn't boot DIRECTLY into TWRP, but boots to the white-screen "stock" recovery. The trick is to tell it "Yes" to both reset prompts. (It doesn't actually reset your stuff.) After this, it will take you to the TWRP menu.
When you get to step 14E, DO NOT FLASH SuperSU!
Instead, flash the ReStock zip.
After flashing ReStock, follow step 14G, and then flash Magisk 13.3 (latest stable, haven't tested others) from here:
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
I tried this out of order a couple of other times and ended up either having Magisk not following through with install, or developing issues installing certain apps. (Either getting a -504 error from Play Store, or having valid APKs reply that they were "corrupt" when directly installing.)
Of course, all of the stereotypical disclaimers apply-- YMMV, and I'm not responsible if you brick your device, yadda yadda...
No offense, intended, sentra10550. While I'm glad you managed to get things working, the directions were a bit convoluted and I hope my humble findings might help yourself, in the future(?), and any others that may have a VS995.
Good luck, everybody!
)O( NeoHiPPy )O(
Think I'll wait until an easier method comes out for the VS995 to run Magisk lol..
I was UNABLE to do full unroot on my V20 from SuperSu settings menu. It would say "uninstallation failed"
I tried running UPDATE-unSU.zip from TWRP and it did not help. Magisk keeps on complaining about modified boot file.
I am unlocking boot loader, trying to flash Magisk in TWRP instead of SuperSu as per DirtyStanta root method instructions.
I will also flash restock 1.3 right after to stop static and vibration issue.
If it works, ill update my post.

Ok i got it working. It was easier then i thought it would be.
These are the steps i did the very first time i got into TWRP after bootloaded unlock process as per DirtySanta rooting instructions.
Entered TWRP
DID NOT format data>yes
Installed Restock1.3 and Magisk.zip
Wipe cache and dalvik. Says Failed to wipe Dalvik (dont know why but what ever)
Reboot.
Result: Asking for unlock password 9 attempts left. So i have to Format Data>Yes
Re-entered TWRP
Format Data>yes
Reboot.
Root works. No SuperSu needed.
Conclusion:
You have to format DATA not for the root to work, but to be able to get into the phone. If there was a way to bypass that, there would be no need to factory reset to root. Root method would not require you to wipe the phone.
How ever, some apps that i use still do not support systemless root. They fail to do their work such as removing system apps. I cant remove any of my system apps for some reasons. I get "failed" messageevery time.
I was told i need modules for Magisk, but i have yet understood what that even means.
Other apps that use root, work fine. Such as AdAway.org

I am rooted, but not happy with my current state

Hey everyone,
I`m running LineageOS on my phone and am rooted using SuperSU which seems to work, according to Rootchecker and the feww apps I use, which make use of root privileges.
But I`m not entirely happy with my current situation, since it seems that more and more apps don`t tend to work with my rooted phone. So what are my ways out of this?
Can I easily unroot my phone, while keeping LineageOS?
Is there a working alternative to SuperSU, which would enable me to stay rooted on LineageOS without reflashing the OS and use Banking-Apps?
I`ve heard of Magisk, but I am unsure of how to switch over from my current state and I`am not sure whether or not it would solve my problems
Thanks for any help in advance!!
Magisk
You just have to go to SuperSU, then Full Unroot, then download Magisk 13.3 and flash it from TWRP. After that you should have Magisk Manager, if for some weird reason you don't, install it via apk
Then you just go to the settings, tick MagiskHide, then go back and open the side panel, MagiskHide - select the apps that you want Magisk to hide itself from
So I tried to do what you said.
I did the full unroot in the SuperSu App,
My phone rebooted
I shut it down again and booted into recovery
Tried flashing Magisk
But it failed, apparently due to my Boot image being patched by another program and told me to go with stock image
What do I do now? And will I lose any data by doing so? Thank you so much for any help!
Weird, but you can simply dirty flash LineageOS (the same one that you have now, or an update, doesn't matter) and it should let you install Magisk.
I did what you said and installed a delta update using LineageOS Downloader. Had to manually flash it in TWRP since I had no root permissions anymore. But I was able to install Magisk like a charm! Now I have to questions:
1. How do I update Magisk? Using the app?
2. Do I have to flash it again everytime I'm updating LOS?
Thanks for the great help so far!
And what exactly are those moduls? Should I be messing with them?
If updates come they will appear on the status bar and you can download them, and they'll install with the phone on. after that you have to (not quick) reboot your phone.
and about the modules, seriously? what do you think??

Lost root access and can't get it back via Magisk. Help!

Galaxy S8 Exynos [SM-G950FD] Android Oreo 8.0.0
Hello. it's my first time posting here. So I've had a successful attempt at flashing TWRP and Magisk into my phone. Today I accidentally plugged in my charger while it was in the process of rebooting, so it entered my device into kind of a bootloop. I solved this by going into Download Mode and pressing 'Cancel', which prompted my device to successfully reboot and work again.
The problem is that I've somehow lost my root. None of my apps can get root access, CPU-Z says no root available, and Magisk Manager said "Magisk is not installed". Idk how I got to this because yesterday all was working, I assume it's because I got a bootloop or went into Download Mode.
I tried to install the official Magisk ZIP file from the Manager, go into recovery mode, and flash it via TWRP. Unfortunately this didn't work. This is the only solution I can come up with besides reflashing Stock and having to flash Magisk again and wipe all my current data. If anyone has any suggestions please comment down below as I'm kinda stuck rn. They would be greatly appreaciated!

Thanks. I tried the methods listed in the "Lost root randomly" section and unfortunately they didnt work. Do you have any other ideas? Maybe I could "Select and Patch a File" in Magisk's Install but afaik Magisk doesnt have its img./tar. file.
I should probably just flash a fresh stock and redo the root process, but then my data will be wiped and I dont really want that lol

Have you tried the uninstaller through magisk or twrp then try again with magisk.
When trying to re-install magisk do you get any errors.
https://github.com/topjohnwu/Magisk/releases
Also if worried about losing apps/data do a backup before trying anything.
The easiest way is to flash firmware and start from scratch again but backup first.
