I've unlocked the bootloader, flashed twrp from pc and I was going to flash the supersu zip. Unfortunately, when I went in recovery (twrp) and flashed the supersu zip(installation process didn't show any problem) I clicked reboot and the phone didn't boot! It just turns off(no led or similar). I have fastboot and twrp access, I tried flashing omnirom using the adb sideload command, everything went fine but still when pressing reboot nothing happens! I even tried to boot manually (after flashing the ROM) with the physical button but still nothing(this time the led blinked twice).
I used the latest version of twrp for Athene, version 2.82 of supersu if this could help.
Edit: was it necessary to flash a different kernel, as it was a nougat rom? The rooting guide I followed didn't mention that.
Edit: Everything worked fine before Supersu, the problem must be related to Supersu but how can I solve?

So I rooted my Nexus Player running Marshmallow (6.0) using the instructions here:
http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344
My bootloader is unlocked, I flashed the boot.img from the first post in the above thread, (already flashed TWRP), then booted into recovery and flashed SuperSU 2.56 from the 2nd post. When I launch SuperSU it tells me that the SU binary needs to be updated, but it can't do it the "normal" way so I try to do it via the TWRP way, it says it's going to attempt to boot into recovery, but recovery never comes up, it looks like it's rebooting, and just hangs on a black screen. So I tried doing "adb reboot recovery" when SuperSU says it's going to try to reboot into recovery itself and do that before clicking ok, but I get the same results. If I go into recovery via the hardware button, no updating happens. It just loads recovery. If I load up the Nexus Player like normal boot, and connected to my PC do "adb reboot recovery" it loads the recovery fine without hanging on any black screen.
So I'm at a loss here on what to do. Any help is appreciated. Thanks!
So I took the OTA for MM and everything seemed fine. I noticed that if I tried to go into recovery my device would just restart. I flashed the recovery image but the same thing happened. After I tried to flash the recovery file, ADB did not recoginize my device anymore. I flashed TWRP to see if that would work. From the bootloader ADB did not recognize my device but if I went into TWRP my device showed up. I did not install SuperSU from TWRP but when I rebooted I was in a bootloop. So I used the restore to stock tool to reset everything. It flashed fine but failed on the radio file. Now I can't set it up because it hangs at the WiFi screen, ADB does not recognize the device for me to flash again, and I can't figure out how to fix this.

Are you using the new SuperSU beta? The play store / alpha version of supersu is not compatible with MM. I suggest more reading, specifically this thread: http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133/page425
Also, because you did not fastboot flash the LP modem after returning to stock, your radio/wifi will not work. It's not an issue with the phone, but rather user-error. Fortunatally, it is a simple matter of getting you working again.
My advice is: Flash the stock unrooted MM TWRP backup (you should already be on the MM modem) and you should be able to start over. Just be sure to use the appropriate supersu beta, and DO NOT modify the boot image.
What i did stepwise -
1. Unlocked bootloader of my g5 plus
2. Flashed twrp-3.2.3-1-potter.img via adb
3. Booted to TWRP
4. Wiped to decrypt phone
5*. Booted to system to enable usb debugging, enabled it . Transfered magisk , arrow 9.0 rom , gapps to my internal storage of phone
6. Open bootloader , selected recovery mode and got nothing except error "No Command"
So i cannot flashed anything what i wanted to
What and Where i made the mistake ?
How can i get TWRP back?
Thanks all in advance
Solution
1. Flashed magisk17.1 and lazyflasher
2. Updated magisk manager and got root
3. Installed official TWRP app , granted root and downloaded same TWRP.img from which i decrypted the phone.
4. Flashed twrp fom the official twrp app.
5. No irritating No Command error again
The no command screen is that of the stock recovery (that's a normal screen). From your steps, it seems like you booted to system in step 5 rather than back to recovery. It seems that after flashing TWRP, you may have to boot to recovery to fix TWRP as your recovery (else the stock recovery overwrites TWRP). Afterwards, you should be able to boot as normal with TWRP still present.
Easiest way to recover would be to repeat step 2 and 3. Then reboot to recovery in TWRP and that should retain TWRP. Back up your existing system, then flash the ROM, GApps and magisk as desired.

Thanks for your answer sir , but it didn't work
What I did again
1.I flashed same twrp from adb
2. Booted to recovery , but this time TWRP didn't asked password and I could see internal storage in twrp but not on my PC
3*.However I took the whole backup of stock nougat and cross check from restore option as there was backup in TWRP folder. I wanted copy that backup to my PC . But PC cannot detect my phone while in recovery
4. So booted to system and my PC detected my phone but there was no backup in TWRP folder.( But around 6gb(backup) of storage was used but I couldn't see it)
5.Again booted to recovery mode but "No Command" showed again .
I tried several times but I keep losing TWRP and couldn't see the backup which I make
Same problem. Resolved by flashing alternately several times twrp-3.2.1-0-potter.img and twrp-3.2.1-1-potter_persist.img and finally updated twrp-3.2.3-1-potter.img
It's because of dm-verity. You have to flash something like magisk or a custom kernel that disables it *before* you reboot into stock.

I flashed magisk 17.1 and lazyflasher ,i got magisk and root but cannot install modules may be becoz of f2fs bug . By the way i lost twrp after booting to system again and No command still present in recovery mode . I am frustrated Moto software is just pain in head :silly:
Alright so, I've managed to uppercut down to 13a from 1ca, unlock the bootloader, install twrp. Never installed supersu, but when the phone booted to twrp I installed the magisk zip with no errors. After booting the magisk manager never showed up as installed. Installed it manually, ran it, said magisk was not installed and device fails safetynet and pts. Downloaded the latest stable magisk, booted into twrp and tried flashing it AGAIN. This time I get an error that it can't flash it. I'm totally lost here. This is all I lack to have systemless root here. Also I can't seem to boot into recovery via button presses. I keep getting the pink triangle and despite holding vol+ and power, the device just boots normally. I have to force recovery via adb on pc.
Any ideas?
Bueller?

It's his day off
Sent from my LG-H910 using XDA Labs
I kinda ran into a issue with magisk not installing properly and how I got around it was to get your roms boot image file and make a zip of it. Then, go to twrp and flash the boot image, then flash magisk.

You installed the magisk zip and the magisk manager apk? Did you try flashing the rom and installing masik and the apk again?
For some reason on the lg phones it won't boot directly to twrp. when you boot to recovery and it ask if you want to reset, select yes. If you have twrp installed, it will then boot into recovery.
I have not since my bootloader is unlocked I heard u can't go back to stock on the vs995

Nothing i suggested requires stock.
With the phone off
press and hold volume down
press the power button and hold until you see the lg logo
while holding the volume down, release only the power button and press it again and hold
if you did it correctly, you should be in recovery
it will ask if you are sure if you want to reset your phone a few times
select yes, and yes
If you have twrp installed it should boot up in twrp
Or
If you already have the bootloader unlocked, make sure that developer options are enabled
go and enable adb debugging
connect usb cable
use adb to boot into fastboot
use fastboot to boot into twrp
From twrp you can flash the rom zip, magisk zip, and then install the apk after the phone rom boots up
which rom are you using? which magisk zip? which magiskmanager.apk?
Hi all,
So I was triying to update my Magisk through the recommended direct update method. I got a bootloop. Never had any issues with this update method, Magisk always did a splendid job.
Now my only options are:
1. Flash a custom rom (I don't have any stock Telekom roms)
2. Update Android OS to 8.0 with LG Bridge (my goal is to have a stock rooted android os, that's why I'm doing this)
3. adb reboot, flash the latest twrp recovery (at least that's working)
4. flash the latest Magisks without reboot option, just power off and then turn on. And this is stage where I get a bootloop.
I only have v19.3 saved on my HDD. Flashing that is working just fine, not causing any bootloop. However Fake GPS and Pokémon Go are not working with this version anymore. :/ So I'm kinda chess-mated here because of this Magisk bootloop.
Anyone can help me how can we fix this?
I have bootloops with all Magisk 21.x versions, so I'm stuck with 20.4. Can't you download Magisk 20.4 and install it from TWRP? I don't need SafetyNet, so I have no idea if Magisk 20.4 can still pass the check, but at least it would be newer than Magisk 19.3.
I downloaded the previous 21.0 versions from here https://droidfeats.com/download-magisk-zip/ flashed it and it's working. I also tested the previous versions. Seems like only 21.4 version is affected only, which is the latest stable.
I had the same problem: I had Magisk 21.4 and withing Magisk Manager I tried to update to v. 22.0 because I got an update prompt that asked me to do so. Trusting everything was fine I updated but I got a bootloop. I managed to recover from bootloop and get the latest version of Magisk working in my Huawei Y5 MYA-L13 (Android 6.0). For these steps, it is assumed Magisk v21.4 and Magisk v22.0 ZIP files are stored in your storage. This is the way I did it:
Manage to get into stock recovery mode.
This step was more time-consuming than it should have been... This Huawei model with the bootloader unlocked states at boot: "Press volume key up to 3 seconds to enter recovery to restore your device". It didn't... With Vol+ just restarted the device (no TWRP or stock recovery or download mode...) and pressing Vol- it loaded into the bootloop. It took me some time to guess the right way:
Plug the turned-off device into a USB cable plugged into the computer.
Wait for the device to start into "charging mode" (I made up this... I mean wait until the charging percentage appears).
Turn on the device using the Power Button.
Immediately, press and hold Vol+.
The device will reboot. Press and hold Vol -.
The device will get into the stock recovery mode (EMUI Huawei eRecovery).
Try again if this fails... After a few attempts, you'll get it.
Now the device will be visible to ADB. Verify this in a command prompt with adb devices. Mine was listed as 0123456789ABCDEF recovery.
Use the command adb reboot recovery to get into the real recovery mode. I mean TWRP. (It's still there even if it seemed to be it wasn't).
Flash the version that caused the problem. In my case, I had Magisk v21.4 initially, so I installed this same version ZIP I got from the official Magisk GitHub releases section.
Once finished the installation, if it was successful Reboot. The device should boot normally this time, having installed this version of Magisk and not the new one, of course.
Now proceed to uninstall Magisk 21.4 completely using the ZIP file provided in the above URL (step 4) with TWRP.
Follow the official installation guide in the Custom Recovery section to install Magisk 22.0 (that is: having renamed Magisk-v22.0.apk to Magisk-v22.0.zip previously, use TWRP to install it). Reboot.
Your device should boot normally. You'll find a Magisk app where you'll be able to verify latest Magisk 22.0 was successfully installed!!! DONE.
I hope my guide is useful to someone. If so, please like my post to be aware it was useful. Greetings!
TL;DR
adb reboot recovery
Install Magisk-v21-4.zip. This solves bootloop problem!
Uninstall Magisk using Magisk-uninstaller-20210117.zip
Rename Magisk-v22.0.apk to Magisk-v22.0.zip. Install it using TWRP.
Reboot. You have the latest Magisk version v22.0 installed with no bootloop!!!
I've upgraded from v20.4 to v22 yesterday using the new Magisk app, it all went smoothly.
