I just accepted an OTA update on my stock ROM, and now it's stuck in a bootloop. Any ideas for the best/safest way to recover?
I assume you are rooted?
Happened to me in the past and after a couple of forced reboots (like 4-5 IIRC), it just resumed booting and working normally.
Not too sure how / why but it just worked for me.
Download mode / fastboot mode were available (rebooting while holding power and vol down / power and both volume buttons) but didn't change nothing.
Hope this helps!

Thanks - yep it did eventually resolve itself after alot of reboots. Strange. Actually I don't think I'm rooted (at least I don't remember rooting, and there's no SuperSU app in the tray)

Hi,
I flashed TWRP and CM 10.1 but then I got problems with the phone not charging (still having that issue but will post it in another thread). Anyhow I decided to reflash the the stock rom and during the flash the phone randomly restarted. Luckily for me I was able to boot up and everything is working fine. the only problem is i can now longer access my system recovery (power and vol down) or fastboot mode (power and vol up). When trying power and vol down the phone starts up as normal. when trying power and vol up the phone vibrates, the bottom 3 keys light up and then nothing. I have to then hold down the power button to turn the phone off and back on. I hope someone can help me troubleshoot this as I have no idea what to do.
Many Thanks!

Recovery is accessed by volume up, volume down, and power held down simultaneously for approximately 10 seconds or until you see recovery. Not sure about fastboot. Have you tried to see if your in fastboot by using adb and checking for fastboot devices. You may be getting fastboot mode. I forget if it actually said anything on the screen. Good luck!

Try search for a app called Quick Boot on play market.
Hello! Got a problem with my Galaxy S 4. Removed T-Mobile brand, flashed the stock ROM MH5 and unlocked the device by code.
Do not know if the problem existed before, at least following phenomenon occurs: after a certain time (depending on how long the battery was out - more on that below) the volume down button no longer responds - initially Vol button respnds normally, suddenly the volume turns down and I can only press volume up, volume down does not respond anymore - when I reboot the device, it always boots in the mode where I can push vol up to install a custom Rom or volume down for restart - but neither Vol up nor Vol down respond. If I restart the device with volume up + Home + Power button, I can not get into recovery but in Safe Mode.
Only when I take out the battery and wait (approx half an hour), the unit boots normally and the error occurs again after some time...
I also made a factory reset - no success. Somebody knows this phenomenon? Thank you.
Maybe

Try replacing the battery with a different one then see if it works. if not do this:
Download the stock MH5 ROM from SAMMOBILE
Open Odin
Flash this ROM with Odin
make sure that only Auto Reboot and F. Reset Time are the only options ticked
I personally havent had this problem but it might help
EDIT: This sounds like a software issue but if it keeps happening it may infact be a hardware issue with the device itself
Thanks, but I already flashed Stock MH5 and now MH7 T-Mobile branded - when the device is off for about an hour, the S4 boots normally and the Volume up and down works fine, two minutes later Vol down doesn´t respond anymore...it´s weird
I still don´t belive it - tried the battery from a mate´s S4 - mine works fine again, no Vol button errors or startup problems...can somebody explain this to me...crazy ****...
Hi
Nexus 4 wont boot to bootloader/recovery after bootloop even with h/w button combos. Heres what happened:
It was a rooted and unlocked phone running 4.4.4. It couldnt update via OTA. So i thought of unrooting + flashing the stock but with the latest lmy48m using WUG's Nexus Root toolkit. After installation it went on to boot (4 dots flying) . It went on for 10 minutes and thought that it went to bootloop again( ive tried similar things on it before and waited for a night etc. ) . So i tried the hardware button combination (power off then Vol - & Power button combo for bootloader mode and Vol + & - & Power) to go to bootloader/recovery mode but all it does is get to the Google boot screen and go to the bootloop mode. . Then i left it to boot again overnight and its still the same.. I tried a lot of times to get to the bootloader mode and recovery mode with no hope. My pc doesnt recognise in fastboot or adb since then.. Just as MTP device in boot or android device when charging. Searched through a lot of forums but nothing worked.. Tried to remove the back cover and then pressing the button combos - still the same.. What to do next?
Please Help!
Thanks

there is an option of soft-brick/boot loop in toolkit. have you tried it ?
hi.. Yeah.. But the device wasnt being detected at all.. also it required the phone to boot into the bootlader/recovery which i am not able to
Did you happen to save the NRT Log from your attempted flash? Might be helpful to see.
Hey guys,
I feel totally stupid for writing this post but I'm actually out of ideas how to get out of my situation. Also I didn't find any comparable topic here on xda. So let's hope you can help me and a big thanks in advance!
First of all i have a flashed D802 running TWRP and CM13, which worked well the last weeks. I thought about updating to the todays nightly as it is already a few weaks since I did my last update. I downloaded the nightly via the CM downloader and started the installation with running phone. It rebooted into recovery mode and installed the nightly without any problems. After the installation was completed the phone automatically rebooted and this is where the problem starts.
I am stuck in "bootloop?" at the CM logo. It is not automatically restarting after a while but just loading and loading and nothing further happens. I am not able to enter the recovery mode via the factory reset (Pressing Vol Down + Power, releasing after the lg logo appears, pressing and holding the power button again).
This never happened to me and as I am not able to enter TWRP I am not able to install a previous release or a backup. What am I doing wrong this time and what can I do?
Thanks for your support!
have you tried flashing a stock rom?

Actually I don't really know how to do this when I'm not able to enter the recovery mode? Is there a certain way to do this?
In the meantime I managed to enter the recovery mode / TWRP via a mode I don't know how it is called. I pressed vol down + pw btn, released after the LG logo appeared and pressed vol up + vol down. I guess my userdata is deleted by now, which shouldn't be a big deal but I am getting redirected to the recovery mode. I tried to install the yet working CM13 nightly but it has the same problems now.
Now I have two questions:
Does anyone know which part of the system is broken now / which part I need to update in order to get my phone back to life?
Is the download mode working if my phone is rooted? I am able to enter this mode.

yes you can enter the download mode: turn down your phone, press and hold volume up button and connect the usb cable, release volume up when your screan shows dowload mode.
then follow this tutorial to restore your phone back to stock http://forum.xda-developers.com/showthread.php?t=2432476

Thanks! At least the phone is working at all now.
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.
