[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.

[Q] Stuck in boot-loop and recovery mode doesn't work on stock android

I have a Samsung galaxy note 4 with stock android. My phone shut itself off while I was listening to pandora, and when I tried to turn it back on, it got stuck rebooting.
It gets to the Samsung splash screen, and no further. Even when I try to enter recovery mode using volume up + power + home, the splash screen appears with 'RECOVERY BOOTING..." in the corner, but it just reboots again.
I have tried turning the phone off completely using the power button, then turning it on again. I have tried removing the battery, letting it sit, and trying to restart again. I have tried charging it to see if that was the problem, but it's not. If I use volume down + power + home, I can get to the custom OS options, but I have not rooted my phone, so I don't know what the 'continue' options does.
How can I get my phone working again?
Turn off the phone. Enter download mode instead of recovery (volume down + home button + power) and open Odin on your PC and under AP add your .tar file (via Sammobile) and hit OK in order to get stock Touchwiz on your Note 4 again.

hi
firstly ,
If you cannot "factory reset " in recovery ....then and if nothing else works ? and you don't want to take phone to service provider /Samsung service centre .............
last resort is to( but you have to know what you doing !!!!)
is to reflash your device /phone current stock ROM,(that you were on),with Odin /pc..laptop
If you are unsure "how to flash ?" i suggest to Google /search for an straight forward video ,on web /Youtube ?
if so and you can get into download mode ( phone off ,pull battery..... insert battery , volume down + power + home button ) When in download mode ,volume up again and follow normal procedure to flash your stock ROM with Odin
Remember ..that above to flash stock Rom with Odin ,you don't need root.
Also ,in your post above you refer i quote......
"I can get to the custom OS options, but I have not rooted my phone, so I don't know what the 'continue' options does"
i think what you actually mean that you can get into download mode ,???...................
and the volume up is when you" ready " to flash your device and connected to pc/laptop with Odin ...
Also make sure if you know how to reflash ..... that before reflashing with Odin ,you have ticked correct boxes in Odin( .....and how Odin works )
Bottom line ...if nothing else works ,
a reflash of your correct phone ( current stock ) Rom you were on ,should fix it .
good luck

Power off While Stuck on Bootloop

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.

HELP! S8 won't boot after updating TWRP

I updated TWRP to 3.1.1.2 inside TWRP. The issue I encounter now is that my S8 stucks on the very first booting screen. You know the very first screen where it stated "Samsung Galaxy S8" and down below "powered by android".
I can't do anything. It's just like the phone has frozen at that state. Nothing works anymore. Even If I try to turn it off by pressing Volume down + Bixby + power button, it just restart and get stucks at the boot screen again and again. There's NO boot loop.
I'm on europe version of the Galaxy S8
stock rom and rooted (Magisk)
Got TWRP installed but after updating TWRP the phone freeze at the very first booting screen.
Any help would be appreciated!
Thanks for your efforts!
First of all - make sure you have the correct TWRP for your device. I know for myself that by searching google I got the S8+ twrp at first and flashed it by mistake without noticing.
Then try this-
Connect your device to a power socket (pc or wall, doesn't matter)
When you are on the very first screen, turn off the device by pressing Power + Volume down. Your device will shut down and you will see the charging animation.
Once you see it, disconnect the device from the USB and try one of the following:
Power + Volume up + Bixby for recovery mode
or
Power +Volume down + Bixby for download mode
I think the download mode will work, then just flash a stock rom or the correct recovery and try again
I failed right at the second step. Once I connect my S8 to power socket and tried to turn of the device by pressing Volume down + Power, the device turnt off for about 2 seconds and then reboot again to the very first screen. Even if my S8 is on power socket, I do not see the charging animation. So that is why I cannot continue with step 3.
Any Ideas buddy?
EDIT:
I got it enter the download mode
I downloaded the TWRP img from here https://eu.dl.twrp.me/dreamlte/
After enter the download mode, I flash TWRP via odin. It passed via Odin but my S8 doesn't enter TWRP but instead stuck at the very first boot screen.
Any ideas, buddy?
EDIT:
I've solved it myself. Thanks for your efforts!
I got the exact same problem but how did u do it please help me
Hi I just got the exact same problem as you but I cannot get how I would fix it please help???
Edit: I got it to download mode but I do nut understand how I would flash it
The only way around this I found was to Odin back to stock https://forum.xda-developers.com/galaxy-s8+/development/rom-galaxy-s8-t3749444
Then follow the instructions to reinstall twrp using odin https://forum.xda-developers.com/ga...-s8-exynos-t3847712/post77735501#post77735501
