LG G4: Installing SuperSU through TWRP renders device unbootable

FOR LG-H815, bought in Germany.
a) Went through the effort and unlocked the bootloader through LG's official method.
b) Confirmed, several times, that the bootloader is indeed unlocked.(via 'fastboot getvar unlocked' and verifying that the response is "unlocked: yes")
c) Tried to swap the Stock Recovery Mode with TWRP, using 'fastboot flash recovery twrp-2.8.6.0-h815.img'. The process ends in 1 sec. After booting in recovery mode, I find out it doesn't actually flash it.
d) Inside cmd: adb reboot bootloader
fastboot boot twrp-2.8.6.0-h815.img
At this point I am trying to boot TWRP for a one-time job of rooting the device.
-Install>>Select UPDATE-SuperSU-v2.46.zip>>Swipe to Install>> Reboot System
e) After reboot: PERMANENTLY STUCK, will not boot past LG's Logo. It is still possible to enter the Stock Recovery Mode, and Stock Download Mode.
I have repeated the process twice, reflashing the stock ROM, to the same effect. Any help is greatly appreciated.

You're flashing outdated versions of TWRP and SU...

I helped with this problem about 100 times now but I will do it one more time...
Firstly, reflash the stock MM ROM again.. Then download the better looking TWRP 3.0.2-0 from official twrp site -> https://dl.twrp.me/h815/twrp-3.0.2-0-h815.img.html
Now a little explanation. As far as I know in 6.0.X Google changed their policy a bit and the option to root the phone/ flash recovery is locked even though you have unlocked bootloader, and as well system root doesn't work, so instead of old SuperSU 2.46 you want to download newest systemless root zip -> http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133 . Now, since there is no stock modified boot.img for G4, you have to download and unpack the custom kernel like SimpleGX and take it's boot img that you want to flash via fastboot, or you can try flashing boot.img from the Autoprime's V20D flashable zips, I didn't try that one and I will not be able to because my G4 got a bootloop issue that I recovered it of by my self but I cannot boot it up on Marshmallow stock firmware. Anyway once you flashed the modified boot img you should be able to flash recovery and boot it up normally, then flash systemless root and if you used boot.img from custom kernel, flash the full package because you did not flash all the stuff from the package what may cause software problems in the long term I suppose. I think that's all you need to do to root it on MM.

And you would be correct. Although I have to wonder why guides on XDA don't even mention flashing a custom kernel like SimpleGX_KERNEL_H81520X_v1.3.2.zip

Chinese Moto Z Play

Heys guys.
I got today my chinese moto z play from gearbest, it still has android 6 and i cant update it from the system itself, since it says the newwest version is already installed.
What is now the fastest and cleanest way to get android 7/7.1/7.11 or whatever installed? Is there any way to maybe get even original updates after that? So far im in love with the moto z but that chinese restriction sucks really.

First of all your are flashing the wrong stuff, stop before you hard brick your device.
It should be fastboot flash recovery recovery.img and you need the TWRP recovery.img.
---------- Post added at 02:02 PM ---------- Previous post was at 01:57 PM ----------
Follow this guide to unlock your bootloader and flash TWRP, use Alberto 97 TWRP not the Chinese TWRP, after flashing TWRP use the volume button while still in fastboot mode to select and boot to recovery otherwise it will be over written by the stock recovery

That thread is for fastboot flashing firmware and I would stay away from doing that cause you'll end up in a mess.
Flash my stock TWRP flashable 7.1.1 stock rom that's whats it's for https://forum.xda-developers.com/moto-z-play/development/rom-single-dual-sim-t3620551/page17
Or flash any other custom ROM and you'll see why apple sucks.

Updates are working on my rom for a reason. As for no notifications sounds just flash arise sound mod as described in my opinion and the sound works fine afterwards.
I would watch some YouTube videos on how to flash ROMs using TWRP recovery, it's easy as downloading the rom and gapps if required and boot to recovery and install your flashable zips.
Your phone will not get any further updates and you will not be able to accept any OTA cause you're device is the Chinese version.
So saying that and avoiding hard bricking your device I would highly recommend you stay with TWRP flashable zips. I have said many times that sideloading firmware can be an issue on moto devices and if you read there's a hard bricked thread that is full of people who think moto devices are nexus or pixel devices which is wrong.
The bootloader on moto devices are problematic under certain circumstances , so I have warned you! I have had many moto devices and not once have I had a hard brick, I always take the root of lease resistance which is flash custom ROMs.

It hans now on formatting system, why is that so?
The zip with your rom is on my sc card, i cant copy it on the system directly, after 10% or so it stops transfering it to the device itself while its in TWRP.

Working, running now Android 7.1..1, but i cant enable my sim cards anymore? They get detected and they ask for a pin but they just wont get any network connection, tested 3 different ones none was able to get activated.

1. Make sure your device is unlocked.
2. Make sure fastboot is up to date.
3. That's not how you install twrp. It doesn't get flashed. You boot it temporarily and then use twrp to install itself into your current ramdisk.
4. You must also install a GSI afterwards or twrp will not work correctly. Twrp is not compatible with the stock OS because of some very hellish security Motorola has in place.
5. If you have a Verizon, Cricket, or At&t branded G7 Play, none of the above is possible. If you bought an unlocked or retail model and simply use one of them as a carrier though, it is possible.

Device is unlocked. Bootloader is also unlocked. As for fast boot im not sure how to update it. Unless it updates with the system updates. Ive not done them for fear of upgrading the software and then not being able to put twrp on or root it.

Magisk and TWRP problems

Hey guys, first time posting, hoping I can get some help with these very frustrating problems. My device is an XT1952-4 running Android 10 with bootloader unlocked. I'll break this in to two sections for simplicity:
Magisk
I got a stock firmware img from the Rescue and Smart Assistant. (I had to use it to save my device after almost ruining it on a prior attempt with an incorrect img.) I installed the latest Magisk Manager (8.0.4 (4768)), and got it read to install Magisk 20.4 (20400). I used this to patch the stock img. I grabbed the patched img off my phone and put it into my adb folder. I then rebooted into fastboot. Here's how the flash command line went:
fastboot flash boot_a magisk_patched_x2DRE.img
(bootloader) is-logical:boot_a: not found
Sending 'boot_a' (17629 KB) OKAY [ 0.423s]
Writing 'boot_a' (bootloader) Image signed with key
I then tried to reboot to recovery, which resulted in an android screen saying, "No command." I was able to subsequently get to the regular recovery menu by using power + volume up, but after rebooting again, Magisk still says, "Installed: N/A". I've tried this like a dozen times and can't get it to install.
TWRP
With this one, I've tried using two different TWRP builds. (Or at least I presume they're two different TWRP builds.) One is a 3.3.0-0 River custom for G7 Play, the other is from this thread: https://forum.xda-developers.com/t/how-to-successfully-install-twrp-for-g7-play.3979701/
I used the DTBO from the above-listed thread.
I get the same result with trying to fastboot either TWRP img from my adb folder. I get the following command line:
fastboot flash dtbo dtbo.img
(bootloader) is-logical:dtbo_a: not found
Sending 'dtbo_a' (965 KB) OKAY [ 0.186s]
Writing 'dtbo_a' OKAY [ 0.054s]
Finished. Total time: 0.287s
fastboot boot recovery.img
Sending 'boot.img' (22156 KB) OKAY [ 0.486s]
Booting OKAY [ 0.163s]
Finished. Total time: 0.687s
After this, I get to the Team Win splash page showing the version of TWRP, but it hangs indefinitely on that screen. I am able to shutdown by holding the power button. Again, I've tried this about a dozen times with the same result.
I'd really appreciate any help with either of these issues, or even suggestions of other ways to root a G7 Play. Thanks!

TWRP I can't help you with as I haven't tried installing it.
Magisk is partially solved in the thread here.
Check the posts by myself and M47Z.
The short version is that the Moto boot image needs some, rather difficult, manual massaging before you can install Magisk to it.

when TWRP hangs like that after booting i've found in my own experiences that is usually caused from the version of TWRP you are using. Or you could have just downloaded a bad file of TWRP if you didn't use the official website. I currently use twrp-3.5.1 for my g7 play xt1952-t channel. hope this helps a little.

I am pretty sure even flashed with TWRP it wouldn't work.
Some GSI just never boot or always bootloop.
Some I found only booted after factory resetting specifically from Recovery (for whatever reason?)
I would honestly just give up. When i first flashed my GSI i could only find 3 that would boot on the entire internet.
