Power off While Stuck on Bootloop - Samsung Galaxy S8 Questions and Answers

Hello guys, been a while, but I got myself into trouble. For a while I had rooted the phone but one time I rebooted and it supposedly no longer had root. Today I got a notification that magisk updated, so I decided to try it. I booted into recovery and tried to flash. Nothing happened. I tried wiping davlik cache and tried again. What ended up happening instead was that the phone was unresponsive. I attempted to reboot, but instead I got stuck in a bootloop.
I realize the most effective way to get out of it is to flash the firmware via Odin, but since I didn't make a backup I want to avoid that if possible. The problem is that other than the soft reboot (power + volume down) I cannot power off the phone to access recovery mode! I've searched and searched, but have only found ways to soft reset, which doesn't help me access recovery mode.
Is there a way to power off the phone while stuck in a bootloop? Or, alternatively, is there a way to boot into recovery while in a bootloop?
It's so frustrating to not be able to something as simple as a battery pull since the phone is sealed. Is there a way to replicate that to be able to power it off?
Any help would be appreciated.

Hold the power button for 10 seconds.

Hold Vol down and power for soft reboot. As soon as the screen goes off to reboot quickly switch to recovery combo (bixby + up + power) it should boot to recovery

What if Vol down and power don't work, adb, fastboot and device manager don't see it, any other combinations tried too, wait for full discharge don't option. Help plz

Did you manage to get out of this?
Im really scared i bricked my phone now. Everything was working fine but after i did a normal reboot it suddenly would not start up.
Screen is black and the only way i can get a response from the phone is the soft restart (vol down + power).
I need to get into recovery somehow so i can restore my nandroid backup but vol up + bixby + power doesnt work (i assume the phone is on and frozen or something?)

I managed to fix my phone. After leaving it for 24 hours the battery was fully drained. After charging again i could boot to twrp and restore my nandroid backup.

[Q] Note 3 Recovery Booting Loop

I think I may have bricked my phone. I have a Verizon Note 3 - rooted - running Kit Kat with Safe Strap. In the power menu (accessed when I hold the power button down) I accidentally selected boot into recovery mode. Now my phone is stuck in an endless boot loop. It powers on to the 'Note 3 - Custom' screen with blue text at the top that says "Booting recovery..." then it shuts down and starts over again and refuses to actually boot into recovery mode. I've tried taking out the battery and sim card, with no luck... the same result. Can anyone think of a way to troubleshoot given that I cant even get the phone to boot at all? Thank you.

It doesn't sound like your phone is bricked... it just sounds like you're stuck in a bootloop, which is usually fixable.
Try removing the battery again and leaving it out about 10 mins... also press down the power button on the phone for 10 seconds or so with the battery out to discharge any remaining power still in the device. Put battery back in after a bit and see if you can boot into stock recovery (by pressing volume up+home button+power button all at same time). If it lets you boot into stock recovery, see if just wiping the cache allows it to boot back up. If that doesn't work, pull battery... reinsert... boot back into stock recovery and do a factory reset (that will wipe all your data as I'm sure you know, so that's why I thought wiping cache first may be worth a try--even though wiping cache alone probably won't work). Hopefully, you have made a TWRP backup in safestrap that you can use to restore if you have to factory reset.
If you can't get into stock recovery manually.... or if you can and wiping cache or factory reset doesn't work, then you could boot into Odin mode (by pressing volume down+home button+power button all at same time), and restore the phone back to KitKat 4.4.2 with Odin. Droidstyle has put together a great guide to help restore the phone which you can find here: http://forum.xda-developers.com/showthread.php?p=46461911
I hope this helps you get it fixed. Good luck!
I was reading through older forum posts and came across this thread which may help with some other ideas if you couldn't get into stock recovery to fix it with a wipe.... ( http://forum.xda-developers.com/showthread.php?p=56087194 ).
A couple of the suggested fixes in the thread may be easier than using Odin to go back to stock.

Yotaphone 2 - another bricked phone after update

Hi guys,
My Yotaphone 2 is currently stuck in a boot loop (shows android logo, then black screen, repeat) after a software update. I can get to the 'Downloading...' screen via power + vol. key and so have tried adb/fastboot as suggested in other similar threads. ADB can't see the device, which I guess is probably normal since it isn't booted up, but fastboot seemingly can. I've tried flashing the TWRP recovery which seems to go through fine on the PC end but doesn't seem to do anything at all on the phone itself. Calling a fastboot reboot gets the phone back to the boot loop and power + vol. goes back to the 'Downloading...' screen.
I've also tried using the Yotaphone flashing tool to flash a full android image - this also looked like everything was operating OK on the PC end but didn't seem to change anything on the phone once the process was complete.
Is there anything I'm missing or anything else I can try? Any help/ideas much appreciated!
Cheers.

Do you have any idea what caused the bootloop? (maybe installing xposed or something?)
When you keep vol-up pressed at (not after) the moment the phone vibrates during power on, you will end up in TWRP recovery. There you can at least wipe->factory reset. Don't do this if you have stuff on your phone you'd like to keep though. (you can try to rescue/backup those by trying "adb pull <path_to_file>" when the phone is booted into TWRP)

It was caused by doing an OS update (wasn't rooted or modified), I've only since tried installing the TWRP recovery and using fastboot to flash an official image to fix the looping. Flashing TWRP appears to work according to flashboot but holding the volume up key at the vibrate on power on doesn't do anything sadly.

Maybe I should rephrase: the vol-up should already be pressed once the vibrate starts. For a timing-insensitive, fool-proof (no pun intended) way you can enable bootloader (like you did before: you get the Downloading... screen). Then keep vol-up and power pressed together, after 15 seconds the device reboots hard, keep both keys pressed until you see TWRP 'curtain' screen, then release.
Did you try to use the YotaFlasher Windows application to reinstall an official ROM and restore factory defaults? You can get it from here, also download a ROM for your region here.

Hard brick or soft brick {URGENT PROBLEM]

Recently my s IV just went nut,
It keep reboot and stuck in a samsung logo,
which is occasionally fine and all we have to do just to access recovery, BUT!
IT does not work,, i cant access recovery by pressing the button, and the bootloader is also restarting which is why i can't use ODIN at all.
*It can't access to TWRP/Recovery and the Bootloader (Vol Down) also got bootloop.
Any tips will be pleasured.
Sounds to me like the power button is stuck.
Try to get it unstuck.

S7 Edge Bricked

I recently (successfully?) rooted my phone, but couldn't make phone calls or texts so I tried factory resetting it. The factory reset worked but I still had the root and I couldnt make calls or texts, so I tried multiple times to unroot it through Odin and it said it worked on my last attempt, but now my phone is stuck on a black screen and a blue LED pops up. I get no vibrations or feedback from my phone. I've tried all the combos to reset, down home power, down power, power home up, home power, all of them. My only hope is to let the phone die of power and recharge it and see if it will work. Does anyone have any ideas? When I plug it in to my computer it wont detect it either.
check your IMEI with *#06#!
when you have no IMEI you need the EFS BackUp...hope you have it.

power button + volume down. When it reboots, quickly get into download mode the same way you would normally. And same as above post, EFS back.. if it's not resolved from factory reset.
I have had this problem.
If you just hold power vol- down it will reboot and when reeboting, just keep holding the same buttons until you get the Download Mode.
If not try holding power vol- up until geeting into recovery, then go trough download mode from there.
You just have to hold the buttons down, it wil maybe restart but just keep holding these buttons trough the restarts.
In download mode you have to do a fresh install with a rom of your choice from Sammobile, orginal firmware.
And remember to never Factory Reset your phone after innstaling ROOT and Recovery.
The best way to do factory reset after these are firmware flash trough Odin.

A5 2015 (SM-A500FU) bootloop, can't go in recovery or download mod!

Good evening everyone, i'm having a serious issue with my samsung A5. It was rooted, with custom recovery and custorm rom (Android 6.1 i think).
2 Days ago, a chewingum got stuck on my screen. I tried to remove it with nail paint remover, it did the trick but then my home button stopped working: the button itself can be pressed normally, but it won't work. I also experienced randomly long home button press actions, so i decided to turn them off. I thought that few drops of liquid may actually have gone beneath the home button. Few hours later, i experienced more issues: volume going up without anyone pressing the button (and the buttons are not stuck at all, and that side never got close to liquids), power button not doing his job etc. I tried to do a soft reset by recovery (cleaning cache and dalvik) but i ended up aslo factory resetting it for a distraction. Reconfigured the device, everything was back to normal (except the home button) but then i also experienced a couple of random volume up and crashes upon making phonecalls. SO i decided to reflash the entire rom, downloaded it + gapps, put into the decide, rebooted in recovery. Wipe cache, dalvik and also system i think, then i tried to intall the zip files but they were not there (probably i should have avoided wiping system, i get confused sometimes). I turned the device off and on, and now i'm stuck on bootloop (regular mode), can reboot it but it seems i can't go in either recovery or donwload mode (so no odin flash). Device is not recognized by the Pc. I keep rebooting it with power + home + volume down and as soon as i see the screen turn black, i try to press again volume up + home to enter recovery, but it goes straight to bootloop.
Any idea on how getting out of this situation? Thank you in advance

Sadly, no software can fix broken hardware, it's probably best, as you'll now know, not to pour chemical liquids onto electrical devices, and just what kind of chewing gum exists that requires such extreme cleaning measures from a flat, non-porous surface I'll never know.
That said, as for rebooting, a force-restart on your device *doesn't* require you to hold Home+Volume down+Power, that should only reboot you to bootloader/download mode.
Try again only holding Power+Volume Down. THEN, when your screen goes fully black, immediately switch to Power+Volume up+Home.
You should then boot into recovery mode without any loop.
Good luck!

I didn't dip the smartphone into a cup of liquid, i just took a piece of cotton, poured a bit of nail pain remover (don't know the exact name in english, sorry) on it and then scratched the part where the chewing gum was on (on the soft touch back key, which works 100% fine).
I am trying using the method you described, but it seems i can't go into recovery. Maybe i'm not quick enough! will keep trying. If you have any other suggestions i will be glad to hear that!
You could try to make a USB jig, or buy one off of eBay. They're really cheap. Its basicly just a resistens that force the phone to download mode. It have worked fine for all my Sammy's including A310 so it probably works for A (15) series as well.
Just put it in USB connector and press power for a few secs and you should be in download mode.
Just an idea if everything else fails

go to samsung
A hardware problem could NEVER be fixed by software ways... Unfortunatelly...
It seems that liquid made some changes on your PCB (maybe dissolved some isolators inside??)...
Anyway, go to service or replace it!
Hello everyone, i've updates about my problem and i would be glad if you could kindly point me in the right direction.
I purchased an USB Jig as suggested by one of you guys, i forced the device into dowload mode and installed a fresh stock firmware + custom recovery. When i try to boot i get a bootloop on samsung logo, and can't go into recovery probably because of the broken home button. I would like to enter recovery by using ADB command, i used to do it in the early days of Android but i'm a bit rusty and all the guides tell the procedure from an already functioning device. Since i can start it properly, is there a way to reboot it in recovery via ADB?
Thank you in advance

if you can access Download mode try this. hold volume down+home+power button. once the screen is black simply turn your finger to volume up while still holding the power and home button then release when SAMSUNG appears.

Thanks for the suggestion, but still couldn't get into recovery. I think the home button is really broken, therefore i need to access recovery in another way.
Cause i flashed the stock samsung firmware twice with odin and i can't still start the phone properly, every guide says that a wipe of cache and dalvik solves the situation. But i need to get into recovery for that.
I can't go into recovery with normal procedure probably because the home button is not working, and all the guides about adb commands say that you need to plug in your phone when it has fully started. So i either need a way to force the device into recovery with my computer, or a firmware that once flashed doesn't give me bootloop
