I'm starting to have boot looping problems and I tried to flash carbon latest nightly. I did everything right but it gets stuck on "your boot loader is unlocked and/or it gets stuck on carbon boot screen. I can't get to the fastboot and adb/fastboot won't recognize the device. If any help that would be great.
Well let's take it one step at a time.
First, I would try to boot to recovery and flash a stable backup - you have one of these I hope? So power off the device, and hold vol up + power to turn it on. Should boot to recovery.
If you can't make it into recovery for some reason, you should be able to make it into fastboot/bootloader mode and use the FXZ thread to restore your phone to stock. To do this hold power + camera, should boot to a selection menu.
Good luck.

I know I know, I'm an idiot. I've done this a few times before on my old Droid X, but clearly don't have the experience to be doing this. I now have a RAZR MAXX HD and was attempting to flash RageHE v1.1. Here's what I did and where I am: I unlocked, rooted and flashed stock system, kernel and radio as well as TWRP recovery using Matt Groff's utility. I made a backup in TWRP and then wiped dalvik/cache etc. I then mounted system etc and it asked me if I wanted to reboot. I did, and now I'm stuck on the unlocked bootloader screen. It won't even power down -- I can hold down vol +/- and power and it will temporarily power down, but as soon as I let go it powers back up.
What do I do??? Am I screwed?
well I managed to get it to power down -- I read on droidrzr.com that I could hold power + vol +/- and then as soon as it powers off, quickly press vol +/- again to avoid it powering back up. So now at least I'm powered down, but what do I do next?
OK I think I'm good -- once I got it powered off I was able to power back up using power + vol +/- and boot into TWRP where I restored from my backup. Sorry was freaking out a bit -- shouldn't be messing with things I don't understand well enough

I messed up with 4.4.4 ROM and it stucks at HTC Logo, asks me for pin and that is it. It even doesn't start the setup wizard. I need to boot in recovery mode to get my nandroid backup.

You have a custom recover installed? Why not hold the power button and vol up for 10+ secs. Once off....hold vol down and power button then toggle to recovery.

you could try using adb commands

You likely encrypted your phone which means you will have to wipe it to recovery.
App called quickboot on Google play. Gives choice of recovery or bootloader or normal.
Somehow it passed HTC logo and could fix it. About the app I couldn't get it to home screen. It was fresh install 1st boot and by default fast boot is enabled. That's why I asked how can I enter recovery with fast boot enabled. It can be useful in the future because I like to test out some ROMs.

So, I have learned my leason. I will not use a toolkit again!
I was trying to go back to stock using Skip's toolkit. It got all the was to flashing the boot.img and began to reboot
The phone is now stuck on a boot screen. I have trying holding all three buttons to access fastboot but the screen just stays black until I let go. The phone then just turns back on and goes back to the boot animation.
Any ideas?
For boot loader the correct keys are volume down and power. If that doesn't work try http://forum.xda-developers.com/google-nexus-5/general/bootloader-bootloader-nexus-5-t2746343
I don't think you can brick both bootloaders with that toolkit but ... i guess you never know.
So, I got my new OnePlus One today and I tried to get CM12 onto it. I was following the [GUIDE] How to Install CM12 on the OnePlus One- Android Lollipop/5.0 on the OPO forums, and everything went well until I tried to get the TWRP on there. I flashed the recovery and rebooted the phone. I turned it off and then tried to boot it into recovery but it doesn't, it just hangs at the OPO logo until I hard-restart it.
I've tried factory resetting it and doing
fastboot oem unlock
but nothing happened. The factory reset pretty much just reset the phone. I think I might've messed up the kernel. How do I fix it?
EDIT 1: I've tried reflashing twrp recoveries and nothing. When I hold power+volume down, it powers on, shows the one plus logo, then reboots and just goes to the lockscreen.
UPDATE 1: I managed to manually flash all the CM12 files and use lollipop. I haven't tried the recovery yet but I'll keep you guys updated (if any of you even care).
UPDATE 2: Apparently flashing CM12 made the recovery work. Everything works as it should and the OTA to the most recent CM12 worked perfectly.
You're probably doing the button combo wrong. Hold volume down, then hold power (so you're holding them together), when you see the boot logo let go of power but keep holding volume down until you reach recovery.

I was curios and enabled advanced reboot to try and boot into recovery and it worked (after I had flashed CM12). Everything's working now.

How did you manually flash CM12? I think I'm having the same trouble you were having. I used the oneplus toolbox from the forum to unlock the bootloader, then flash the TWRP, but no luck in getting into recovery mode. It just boot loops with the oneplus logo until I release the volume down button at which point it then boots to the lock screen.

@Heisenberg I'm also having trouble getting into recovery. I've tried the different button combos (power + vol down; power + vol down and release power) as well as the advance reboot options to get into recovery, but they all fail. I get the 1+ logo and after I let go of the volume down button the screen goes black and boots again to the 1+ screen and then to the lockscreen. It's almost like it doesn't recognize the recovery. I tried putting the stock recovery back on using the image in the OnePlus One toolkit folder, but that one doesn't work either. In addition to unchecking the "CM Recovery Update", are there any other settings that could be causing problems?
For background info, I initially used the toolkit interface to unlock the bootloader and then flash the recovery. The bootloader unlocked with no issue...it wiped my device and I was in sync with the "How to root" video posted by alex.inthi. I got sidetracked after the (seemingly) successful flash of TWRP onto the phone I kept getting booted into the Cyanogen recovery. I realized out that I needed to uncheck the setting to keep it from overwriting TWRP and after that was not able to boot into recovery. After finding your beginners guide (thanks, by the way, very well written) I tried using fastboot from the command line as you show, but still no luck.
Thanks in advance for any help...

Okay, I must have been having a special kind of moment - I've got TWRP 2.8.7.0 running on my handset now. I may have been holding the volume down button too long, or it may be that I was using an older version of TWRP, but I'm going to go with the former. I've also been able to successfully flash and boot into Philz 6.59.2
Having the same problem
I am having the exact same problem and cannot seem to find a solution. Recovery screen just doesn't appear, but goes to lockscreen.
Tried erasing, flashing both twrp, philz etc., but nothing works. The phone doesn't recognize the recovery status. Advanced booting does the same.
Update CM-recovery is checked off, phone is unlocked. I've followed every step of the big guide down to every detail.
Is manually flashing the 12.1 ROM the only way and in that case: is it hard for a relative newcomer?
Hello, I bought a OnePlus one (came with CM11 - 4.4.4) and followed the standard steps to root it
1) unlock bootloader - successful, phone got factory reset, checked the status using fastboot
2) Flash custom recovery (TWRP) using fastboot - always "okay" message
3) The phone DOES NOT boot to recovery after this - it gets stuck at the 1+ logo, or remains stuck for a few seconds and goes to normal reboot. -I've tried using fastboot to reboot phone while holding down volume button
Please help! i've look this problem up and haven't found a solution.
I tried 2.7.0.0, and the latest 2.8.5.1, along with 2.8.6.0, along with trying to use the one plus tool kit. Using the toolkit, even flashing the stock recovery, then booting it didn't work.
after you flash recovery in fastboot, do not issue the fastboot reboot command. you need to manually power off the phone by keeping the power button pressed till it powers off

As the other posted mentioned you have to fastboot flash twrp (2.8.6.0) then power off phone and use volume down + power button combo to get to recovery. Its flashing but if you boot to OS it will be overwritten by CM recovery hence booting directly will alleviate that
Boot into os, enable dev options by tapping the build number a bunch of times in settings-about phone section, go back and go into settings-developer options, make sure "update cyanogen recovery" is unchecked. Flash recovery again, and like people have said, power off the phone and use volume down and power buttons together to boot into recovery.
Thanks for the quick replies guys. I have tried all the above s and none of them have worked
Should I try unlocking the bootloader again?
I recommend going to this guide and following it closely: http://forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471
As for which version of TWRP to use, I recommend this version: https://www.androidfilehost.com/?fid=24391638059059048
