Tried to restart S7, now it won't boot again. Stuck on Galaxy logo. - Samsung Galaxy S7 Questions and Answers

Hey,
for the past months my S7 worked as it should. I am using Lineage OS. Today - as I was using WhatsApp - I got "Not responding" errors. I tried to open the settings but even here I got the same error. So I tried to restart it. Held down the power button and selected "restart". But then it just reached the Samsung Galaxy Logo and started again. Over and over. Recovery mode does not work, but the Download mode does. Right now I am trying to stay in the Download mode to drain the battery (it was at 100% when the error occured) to get the S7 to shutdown completly so I can try to get into Recovery mode again. I want to backup my data. Does anybody know what could have caused that behaviour? Or maybe can tell me what to do?
Thank you very much in advance
€dit: After the battery was empty, I connected it to the power cable and it went straight back to the reboot loop.

Do you have twrp installed? If not flash twrp with Odin and reinstall the lineage you were using from the sd card (the exact same version). All your stuff should be saved.

TWRP is installed, but I am not able to get there. Just into Download mode. Should I try to reinstall it or could that create other errors?

Problem with lineage is it could be any number of errors. You have a slim chance of rescuing your phone if you can reinstall twrp then the version of lineage you were using.
If this doesn't work then it's back to the start I'm afraid.

Plug it in and leave it for at least 15 mins. It doesn't matter if the light doesn't come on just leave it. You need at least 50% charge before flashing and rebooting.

[Q] Bricked GT-P5113

I was trying to root my Galaxy Tab 2 for the first time. The process started, but failed. Now I'm stuck on the "firmware upgrade encountered an issue" screen. The device will turn off and back on, but remains on error screen. Seems to be trapped in download mode (as I can still see the download progress bar). Go Mobile and Odin say the device has connected to PC.
Anyone know of anything to fix this? Should I just revert to stock ROM and try again later?

can you actually boot in to download mode? power and vol down after power off? I know you say it seems to trapped in download mode but they're different! If you can, flash a stock rom from sammobile.com

I cannot boot into download mode. When I turn it off, it simply flashes off for a few secs then goes back to the error screen on its own. Does the same thing when I turn it back on myself. No logo screen. No droid. Nothing.
EDIT: Unplugged device entirely and retried the stock ROM in Odin. Finally worked! Looks like it might be fixed now.

I think my cord might have an issue (or they're just testy in general). I was noticing the battery wasn't fully charging for a while before all this. After the whole brick issue, I plugged it in to charge and it started flashing the "loading charge (empty battery + loading circle)" screen on and off until I unplugged and re-plugged it. I suspect that this is why the rooting failed in the first place.
Hi you may use cf auto root for gt p5113 with odin.this happend to me couple days ago.

I also bricked my tablet. Searched wide and low for ideas on how to fix. But I can't find a thing. I cannot get into Odin mode or recovery. Just hangs on the battery charging screen. My windows 7 computer can't even recognize it in Kies or odin. Yes the tablet is rooted.

boot loop - can't navigate bootloader to get into recovery mode

hi there,
I'm running CM11 nightly late feb. For no apparent reason my phone went into a boot loop this morning (n.b. I didn't flash a new rom or installed a new app). Now it constantly reboots (literally) and doesn't get further than the CM11 boot video or google logo.
If I press volume down and power, it will head into bootloader - but - I can't navigate beyond 'shut down' or 'restart bootloader'. It doesn't execute two consecutive volume up or down commands. In other words, it's impossible to get into recovery mode. Also, because my phone doesn't boot further than the video or logo, I can't make a fastboot or adb connection via my laptop.
Does anybody know how I can fix this issue? I'm clearly running out of luck. Many thx in advance!
reflash recovery?
Try to boot into recovery with cmd: fastboot boot TWRP.img (TWRP or your current custom recovery)
Then restore a nandroid backup or wipe data/system/dalvik
You can still flash the factory images. Fastboot mode is enough. Guide

Stuck power button. Mash the power button really fast for 20 seconds to unstick whatever is in there.

can't flash anything, because phone is constantly rebooting. Have opened up the phone and took the battery out for 1 minute. Didn't help either. After starting up the phone I get stuck in the boot loop again.
Anyone else an idea?

The phone doesn't reboot in the bootloader right?
If it doesn't either do what primokorn said or flash the factory image.

Well the issue is that it only stays for a fraction of a second in bootloader, which gives it enough time to navigate one step up or down. Not enough time to get into recovery.
How can I do what Primoken said? It doesn't seem to be possible to do a flash when the phone is constantly rebooting?
Thx for helping me out guys, much appreciated!

Have you ever kept your phone in narrow pocket? Because it's definitely sounds to me like a stuck power button.

It's not a power issue. Also unscrewed my phone to see if that was what caused it. Nothing in there, mechanism functioned correctly.
UPDATE: For some reason my phone booted up out of nothing. I managed to flash an older ROM via CM Updater (through settings)- which seemed to work. Apps were updated and it was running normally. But after a couple of minutes it restarted out of the blue and now back to square one again.
Guess there's a chance I'll probably get a normal start up soon. Is it a good idea to do a factory whipe restart through the settings menu? Or is Primokorn's method safer?

I don't get into download mode at the first try i keep trying many times, maybe it's the same thing for you too. apparently i need to flash stock rom with odin on download mode, that's what you should do too if you get to download mode.

Noobie here, and not sure if I know enough to make much sense.
I had a similar situation occur today.
New to me but a 2nd hand p600 which rooted today and then I used Odin 3.10.6 to flash TWRP and found myself in a boot loop similar to the description.
I panicked bigtime and feverishly googled my way to to this message thread and my hopes were raised when I read the OPs message and then got dashed to find no solution posted .
After perhaps 20 attempts of getting combined button pushes and releases correct. (it never happened ) I was desperately trying almost anythiing and then got to TWRP File manager, then Reboot, then System, then Normal Reboot and finally Success! I got the regular reboot. Phew!
Hope it helps
Well, I let it sit over the weekend and the battery complete depleted. I was then able to get into TWRP and Download mode when I applied power, I have since flashed a new rom and whewwww, up and running again. Before the battery went dead, it wouldn't do anything but reboot.....

LG G3 Bootloop

Hi guys. I have an unlocked AT&T LG G3 D850 and I cannot for the life of me figure out why it's stuck in a bootloop. I've tried just about everything but nothing works. I'm able to access both recovery and download mode, but every time I exit it, I just get thrown into another bootloop. Strangely, I didn't do anything to the phone recently, and it was working absolutely fine minutes before I noticed the bootloop.
First thing I tried was wiping everything and reinstalling the ROM. I am rooted and was running a Marshmallow distro of Resurrection Remix, with TWRP 3.0 (I think) running my recovery. I booted into TWRP and cleared everything, reinstalling the ROM. Didn't work. Okay, so maybe the ROM is to blame. Tried some different versions, still nothing.
I then tried flashing stock firmware using download mode, and kept getting errors at the beginning of the LG flash tool utility. After switching USB ports, it started working. However, after about 30 minutes, it would fail, and I would get a message saying it couldn't communicate with the device. I tried this multiple times to no avail.
Eventually, I ended up running the program one last time and left it for a couple hours. When I got back to check it, I was super relieved because the phone had apparently successfully been flashed back to stock firmware. Keep in mind this process usually only takes 4-8 minutes, whereas my phone took hours to get it done.
Finally, I booted the device, full of hope. NOPE. Bootloop again. I tried resetting it using the volume down combo, but it stays in a bootloop every time.
I am running out of options and getting desperate, and I really don't wanna fork out the cash for another phone if I don't have to. Any help would be greatly appreciated. Thanks everyone!

When flashing an AT&T choosing that will make the phone boot into mini OS then you'll select reset/restart and it should boot unless there's an hardware issue

It says download failed at 517 seconds. "We can't communicate with phone." Meanwhile, the phone is back at 0%. Should I leave it for a couple hours like I did the one time it actually worked?

Yes. However, I'm not sure if I was able to manually boot into download mode or the phone automatically did it. I did pull the battery before connecting the phone, and I did hold volume up. I just don't know if I physically put it into download mode myself.
New issue. Got to about 89% when I get an "fboot fail" error message. My phone is bootlooping again.

A51 stuck in TWRP bootloop

Today, I flashed the latest firmware onto my phone, it had a few boot issues but I managed to finish.
Then I noticed that (I KNOW I AM DUMB) forgot to backup the data in my internal storage as well...
Now I tried flashing TWRP because I noticed the internal storage shows up as ~4GB, which is about as much as I had free space left before flashing.
Problem: my phone is now stuck in a TWRP splash screen bootloop and doesn't want to reboot anywhere else.
I used the exact same TWRP ROM I had previously used on Android 11 and it worked perfectly fine (ROM: https://forum.xda-developers.com/t/...-sm-a515f-one-ui-3-0-dub1-android-11.4231543/)
Now I can't get out of TWRP anymore (not even into download mode or anything) and all my hope is pretty much lost.
Do I need to wait for the battery to fully drain? Would it still be possible to recover the data from the internal storage (since it wasn't encrypted and appears to still be there?)
Thank you in advance to anyone willing to help!
For the record; I got it out. Still pretty stuck fixing the OS, I gave up on the data since it wasnt too important anyways
The same issue

Yes, I let the battery fully drain - my trick to get into Download Mode was to hold Power + Volume Up once the battery drained and then connecting the charging cable connected to a computer while holding down the buttons
Then flash stock FW
