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?

Constant Bootloop

A very weird thing happened to my phone. I was texting and the phone shut off and started to bootloop.
It only boots to the "Google" and about 1 second or 2 into the colorsplash boot animation
THEN it boots back to the "Google" and loops from there.
Has anyone had this problem before?
Also, plugging in to charge the phone causes it to bootloop as well.
I am on stock google rom.

This is called a bootloop and nothing short of a factory reset or a reflash of stock will fix it.

It actually got to a point where I could do a factory reset.
But it still does this.
So I dont know what to do next.

So you've reflashed stock?

Yes the phone actually got stable enough for me to use Nexus RooToolkit to flash back to stock & unroot. and now it still goes into the "GOOGLE" Bootloop

i dont want to scare you, as i can be very wrong here.. but i have ran into a few more users and phones who kept bootlooping no matter what. and every single one of them eventually found out it was an issue with their storage.

There is a post somewhere on here that tells you how to go from ColorOS to CM11s..
I had some problems also.. I went from CM11s to ColorOS back to CM11s and got reboots and FCs...
You need to manually reflash all the files through fastboot and not through recovery... after I did that, worked no problem...

have gone through a full hard brick where I couldnt even boot into anything (even fastboot!). this guide saved my oneplus one
follow it and your good to go
NOTE: this is for a complete full hard brick.. you wouldn't see anything at all jst on the screen when you try to boot it. jst a small vibration and jst nothing on display.
Wrong kernel : black screen, no fastboot, no adb, no factory reset

thank you so much for your help.somehow i got it back up and running

Had the same happen to me. It didn't want to go into recovery gave a message it failed. With some patience I manged to get the button combo to work for fastboot then did a flash-all of the factory image. I think the trick was it had to be plugged in to get to download mode and I think you may hit the power button slightly before the volume down. It was a bit tedious. I tried to recover the boot.img and that trashed things up worse, got no google loading logo or something odd. Anyhow flashing the full factory image fixed things!
Glad you got it resolved, maybe this helps someone else in the same spot.

Help!? Bricked my T-Mobile OnePlus 8.

Hello!
I am kinda new and tried to use the tool that's posted but my phone won't power down, it just loops back to fastboot no matter what I do.
Vol up and vol down with power only restarts the loop .
The tool sent something to my phone though last night because now it won't even go into crash dump, just loops fastboot.
PC is still seeing my ADB Android device though.
I had to buy a Nord 10 so I'm not without a workout phone.
Anyone please?
Thank you!

Make sure the phone is unplugged when you're powering off. When plugged in it won't ever turn off just reboot. Try that and use the msm tool to restore your device to factory settings. If it doesn't work ping me on here and I'll try to help more

Thank you so much! I was plugged in..let me try that.
I'll let you know!
I really appreciate your time!

Even unplugged it's the same.
Just boots back to fastboot.
Start, recovery, and power down do nothing.
I can show barcode and get into fastboot and nothing else

Try getting into download mode if you can.or safe mode anything that could break the cycle of reboot. Hmmm other than that you could always try contacting OnePlus over the phone and see they would remotely do anything or via fastboot commands. They have a lot more tools than we do

https://forum.xda-developers.com/t/...ck-twrp-factory-image-stock-recovery.3398993/ here my friend the tool is called all in one. get a fastboot rom from oneplus and flash it with the tool and ur phone should be good. If you are having issues get an ota update that and flash that through the built in system flasher. Hope this helps msm downloader shouldnt be necessary if you still have fastboot

Use the flash stock factory image option

Just do what the guys said above, use MSM and it will fix everything for you, there are a lot of instructions on YouTube
