Help! Stuck on TWRP loading. I can't even turn off the phome! - Samsung Galaxy S7 Questions and Answers

So I have Galaxy S7 (Flat). It had installed TWRP with Magisk on stock Android. I decided to install LineageOS (https://forum.xda-developers.com/t/rom-q-s-lineageos-with-microg-for-samsung-s7-flat-edge.3921094/) (clean install using TWRP) and it installed successfully, everything was fine, I've turned my phone off and on few times and system was booting without any problems.
But then I decided to boot into TWRP (using key combination) to install magisk and... it's stuck on loading screen forever.
I can't even turn it off ! And my phone is getting hotter and hotter. Please help !
I can't turn it off, because simply holding power button doesn't do anything.
I can restart it by holding power + volume down ,but it just opens TWRP again.
I've read I could boot into Maintenance Boot Mode ,but it requires to turn off a phone, which I'm unable to do.
Only thing I am able to do is to boot into Download Mode, but it doesn't change anything (still cant turn off phone in this mode)
Should I try to disassembly the phone and take out the battery manually? I don't really see any other option.
Did I bricked my phone ?
@edit
I have backup of stock system made by TWRP, but it doesn't change anything as I cant use TWRP.
I didn't install LineageOS custom recovery.

Ok, so I left phone overnight to deplete the battery. And it didn't work ! I thought that battery is dead and phone is off, but the moment I've plugged the power cord it automatically turned on into TWRP screen, like a zombie !
However I've solved the problem. As I was able to get phone into Download Mode (by holding power+volume down+home) I used Odin. I've installed newest Odin on PC, Samsung USB drivers and flashed the newest TWRP tar. Although it was scary, I was almost sure I've bricked my phone. Adb/fastboot were not detecting the phone.
And after re-flashing TWRP everything works fine. Also LineageOS booted like a charm, it stay intact.
So, it seems that installing LineageOS somehow corrupted my TWRP, despite that I un-ticked the option to install LineageRecovery ,so technically it shouldn't mess with it at all.
Anyway, problem solved.

[Q] Touch the android to begin w/ broken power button

So here's a puzzle.
My nexus one has a broken power button, and I learnt to get around it with apps like quickboot, that let me boot into recovery automatically.
I flashed cyanogenmod 7 (nandroid before that) and turned the phone on. It worked perfectly, but I had forgotten to flash gapps, so I do.
Now I turn my phone on and it boots to the "Touch the android to begin" tutorial/thing. The android lights up when I touch it, but doesn't change screen. It just stays there. Now that is apparently not unheard of, and the advice is to wipe or reflash the rom and/or gapps. The problem is, since I don't have a power button, I can't go into recovery mode from the bootloader, I'd have to do it using the quickboot, but I can't because the screen is stuck.
Is there a way to flash a rom from a pc? Any other ideas? Anything is much appreciated.
Try a method called "passimg" which is used to revert to stock android. I don't have much to time to look into it for you, but it's possible, because i had to do the same for mine. You place the file on your sd card root then boot (using the battery removal/insertion method) while holding the volume down button. You'd have to re-root then you can try to recover again.

Need help with my phone

Good day everyone,
I have been facing a huge problem in the past weeks after I have done one mistake.
I was installing a newer version of TWRP recovery and instead of installing the image I installed it as zip.
My OS was gone, I couldn't get it to "recover" my OS in any way. The kernel seems fine.
I have tried to use a micro SD and USB cable to install a new ROM but TWRP couldn't detect my SD card and my PC couldn't connect to my phone.
I also wiped my whole data.
My phone doesn't boot in the recovery unless it's not charging and start with ONLY pushing the power button.
Holding power and volume up will make it vibrate 3 times and restart.
Charging the phone makes it stuck on the android logo after the battery status.
The phone overheats and the battery drains extremely .
The only message I got from TWRP is, "No OS installed".
Other logs are inaccessible or wiped.
I would appreciate any advice
Thanks in advance!
1. Turn off your phone
2. Enter the phone Flashmode by holding the volume down button, then connect to a PC (the led should be green and your PC should recognize your Z5).
3. Flash the FTFs in Flashtool.
Information about how to that can be found on this forum.

This might help.

Stuck in boot animation. Can't get into recovery or fastboot.

I recently updated Magisk from 16.0 to 17.1. The installer asked to reboot after finishing up. After rebooting, however, the phone gets stuck on boot animation. I've tried to let it run all night and I've tried charging/discharging a few times. The bootloader is still unlocked (the opened lock icon shows up under the Google logo on boot). I can't get into recovery/fastboot mode: Holding power+volume down turns on the phone but gives a black screen with backlight on. My computers also don't recognize the phone. I haven't found any similar issues here while searching so I am at a loss on how to fix it.
Possibly related: Charging the phone has been weird for a few months: the charging LED indicator only turns on when the phone screen was on. It seemed to charge slower compared to previously and the OS doesn't recognize that the phone is charging.
With the phone off, hold the volume down button and connect the phone to your computer. This may force the phone into fastboot mode.
Thanks for the advice! Although that didn't immediately work (it still booted to a black screen w/ backlight on), I tried one or two more times to boot holding down volume down + power with the phone unplugged. I got lucky somehow and it finally booted to Fastboot. From there, still neither my MacBook nor my Windows computer recognized my phone (nothing in device manager). I booted to TWRP, and saw that Magisk had .zip's of previous versions stored in /sdcard/MagiskManager. I flashed the last working version, 16.0, wiped Cache and Dalvik, rebooted and finally got through boot animation.
Time to backup!

Click to expand...
Click to collapse
That error means it's the wrong firmware. Flash the stock that was on it before you messed about with custom ROM.
Also please read ALL instructions when flashing custom ROMs, some take 15 minutes on first boot.
UPDATE
the error only happened as i wasnt flashing the very latest stock rom. downloaded from samsung website and now is working fine
phew

Can't enter recovery mode anymore (TWRP)

Hi, I don't know what is happening, but I've been having issues with my phone. I was trying to enter recovery and pressed the button combination for fastboot instead. After that, I tried to get out of fastboot, but it kept going back to fastboot. I noticed holding up for a couple of seconds would boot me into my OS. When I try to enter recovery, the screen goes black and it restarts the phone. It will just keep going in a loop if I hold the buttons. My phone was rooted with magisk and I uninstalled to see if that would help, but it didn't.
I installed an update(I use lineage OS) out of curiosity to see if it would boot to recovery. It booted to fastboot, but after restarting and holding the recovery button combo it booted to twrp and installed the update, then restarted. Now my stupid mistake made my phone unusable. Everything is the same, except Lineage is stuck at the boot screen now. Sometimes it restarts to fastboot, but other times it stays there for possibly infinity.
I don't know what to do. All help is appreciated?
TL;DR Fixed, I think my volume down button was stuck.
Nevermind, I flashed with miflash and still had the problem, then for some reason it worked, but only once. I removed my phone from the case and found that it was booting to os. It is still kind of hard to enter the recovery. I think hitting volume up was cancelling the volume down which was stuck, or something. Now I'm pissed cause I wasted so much time on nothing
