I was on 4.4.4 stock with bootloader unlocked. I flashed custom recovery from fastboot and rebooted into CWM. It was all fine till this point. On next reboot, It booted in OS all fine. I did adb reboot recovery and it got stuck at "No command" screen. waiting a long time ons creen it booted into OS.
I reboot into fastboot to reflash CWM and check but it wont detect my device in fastboot devices. I'm on OS x. I even tried windows (drivers installed) , its the same. fastboot is stuck at "waiting for device".
ps. I installed "recovery-clockwork-touch-6.0.1.6-manta-Wfix-by-damien667.img" from downloadandroidrom.com
Have you tried turning off the tablet, then booting by simultaneously holding the power, volume up and volume down buttons? This is the manual way to boot into CWM. After you are in cwm you should be able to reflash or just reboot into the OS.
uDude
The stock-Recovery is reflashed when you reboot to Stock OS, you have to disable that.

While using the PA Updater app to upgrade my rom, the app attempted to reboot into recovery to run an openrecovery script. While doing this, I believe it set my "reboot mode flag" to recovery.
The tablet boots with the Google screen and then shows the TWRP splash (I'm on version 2.6.0.0), then it reboots and starts again.
I am able to get to the bootloader, but even if I press start or recovery mode it reenters the boot loop trying to get into recovery. In the bootloader was where I saw the reboot mode flag set to recovery. Is there a way to use fastboot to remove that or am I just going to have to do a wipe with fastboot?
It happened to me once. I pushed the power button for 60 seconds as it supposed to do a kind of battery pull, and it worked.

I've done this twice to my nexus now and I think I found a reliable way to restore to running condition. YMMV
1)Boot the nexus into fastboot (power and both volume keys) when you power up.
2)Attach your usb cable from the PC (or MAC I guess, dont have one to try)
3)start WUG Nexxus Root Toolkit. 'Launch' advanced utilities.
4)Test your fastboot with Quick tools. check the button at Fastboot-Bootloader and click 'List Devices' if the box that pops up is empty then fastboot isn't working (I can't help you there and it must be working to continue).
5)If fastboot shows a device then go to "Boot Temporary" and click 'Custom Recovery'.
6)I selected 'Touch TWRP' but CMW may work as well. This will reboot you into (temp)TWRP and from there you can force a reboot that will reset the 'Recovery' flag that has locked your bootloader.
7)Give it a few minutes (be patient for 5 minutes) and hopefully you reboot to where you were prior to this mess.
Long time lurker and couldn't fix my fails without everyone here.
Thanks to all.

I had the same thing happen to me (though i updated from stock 4.4 to 4.4.2 [and i had twrp installed]). I tried reflashing to stock recovery and a few other things but same problem, it kept booting me into stock recovery. I know this is going to sound crazy, even stupid, but just letting it sit there for 5 minutes (at the stock recovery screen) let it work... I was searching for more things to try and it just started booting.... Checking the bootloader again showed the reboot mode flag set to none.

I guess mine worked because I was still on stock bootloader and adding TWRP was an important key but the 5 minutes seems to be the solution after all the rest.
recovery boot loop:- Is coz, one of your partitions would be facing problems while mounting.. So Wipe the Partition and Format it with Ext-2 file format. and reboot the Mobile. Then it'll stops rebooting.
Do you have a Samsung device?
Be warned - there is no such thing as fastboot mode for most Samsung Galaxy devices - you'll be wasting your time doing this and typing "fastboot devices" for many hours!
If you have problems with your recovery, it works to just reflash the CF-autoroot kit, which happens to flash the cache partition too. My problem was similar to the OP's - a bootloop with TWRP's obviously buggy OpenRecoveryScript, which was installing a ZIP file over and over again.
If you flash the CF-autoroot specific to your device, TWRP will be gone, but the phone will boot normally again - with all your data on it - hooray!
Then you install TWRP or CWM recovery as you did originally.
Stay away from OpenRecoveryScripts! I'll be installing a ZIP file in the traditional, manual way from now on, from an external SD card so I can remove the card if I get another TWRP boot loop.

How do you install cf-autoroot when stuck in a boot loop with samsung galaxy S device if there is no fastboot?
My phone is stuck in bootloop too. It shows Twrp at the starting and then restarts. What am i supposed to do? I need help ASAP please
I have a big problem at the moment... I wanted to boot into recovery mode, then an android icon with a red exclamation mark appeared. After I tried to boot into the recovery again using Power + Volume Up, it appears again. Since then I can't reboot my Nexus 10 normally. Bootloader says:
Reboot Mode Flag: Recovery
I think my Nexus 10 is always trying to boot into recovery, but this is no longer working... what can I do to get it work again?
Hope someone can help me with this
Edit: I could finally solve my problem I used fastboot to flash a new recovery that is working, after this I rebooted into recovery and restarted the system. Because this wasn't working, I had to get back to factory settings, but it is working
Hey guys I was trying to flash MIUI 8 on my a6000 lenovo. Bear with me because I'm new to this so I might have screwed up.
Rooted and installed TWRP perfectly. Phone was running kitkat.
I then, through TWRP tried to flash MIUI 8 from http://forum.xda-developers.com/lenovo-a6000/development/rom-miui-7-lenovo-a6000-a6000-t3355692
After first swiping right to install the zip, i got an "error executing binary in zip" error. Wiped dalvik,etc. again and tried again and then I got a MD5 file not found "warning". It was not in red letters and after that message there was no progress bar or anything and the phone just stopped responding. I assumed it wasn't working and few minutes later took the battery out. After trying to boot again it would give me the "mi.com" boot screen (not the default lenovo I used to get) and won't boot into neither recovery nor normal mode. (for recovery boot I'm trying holding both volume buttons and the power button at the same time. perhaps that is different now?)
I'm guessing the flashing was going on and i interrupted it. How can I fix this?
Update: It boots into MIUI now however pretty much nothing works as expected. It wont even go into settings. Recovery still seems botched and i cant boot into it.
TLDR: Recovery broken cant boot into it. Can boot into MIUI with very limited capabilities. Cannot select USB debugging and "adb devices" won't find the phone. What can I do?
Alright nevermind guys I managed to fix it. for anyone wondering or having the same issue, i tried many things but what I think worked is this:
Turnt on my phone in fastboot mode (hold volume - and power button) , connected it to the computer and used command "fastboot flash recovery recovery.img" to flash the old TWRP i had on my computer. After that I managed to boot my phone in recovery mode and reflash the rom properly. The weird thing is, my phone could not be recognized by the computer and "adb devices" gave me nothing back so I thought using any fastboot command wouldn't work. Oddly, it did and it flashed TWRP back into my phone.
Hi,
I did a TWRP wipe (everything checked) to prepare for a restore to stock, but my device is now stuck at the very first "Google" screen with the pad lock icon at the bottom. How do I get it to boot?

So since everything was checked, that means you wiped the system partition. The device will not boot if you do that unless you flash a factory image via fastboot or new ROM via TWRP
OK, I thought wiping /system would just bring it back to factory state. 2 questions now
1. How do I get to recovery when it's always stuck at the Google screen with no adb access? Would I have to wait for the battery to run out (hence turn off), charge it for a while, then use the buttons to boot to recovery, or is there a faster way?
2. I am actually trying to revert to stock ROM (downloaded at https://developers.google.com/android/images#angler) by following step 10 of the Heisenburg guide (https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928) which advises me to use fastboot to flash the individual images. In my case, how do I boot to fastboot?
OK, so I managed to boot to the bootloader and run the following commands as per the Heisenberg guide (using the stock MTC20L firmware)
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash cache C:\angler\images\cache.img
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
Everything was successful, and I did a fastboot reboot after that.
However, my device still doesn't boot up. This time. It's boot loops for a few times before turning off.
I tried booting up to bootloader with power/vol-. Curiously, I can now only do this when cable is connected. If cable is disconnected, the orange LED just blinks once when power button is pressed, and nothing happens. Once cable is connected, then I'm able to boot up to bootloader with the button combination. I then retried the flash process again, but still no go. I noticed after fastboot reboot that the orange LED blinked a few times before rebooting and boot looping.
Kinda stuck now, any ideas?
Try booting into recovery and doing a factory reset. I've had that happen to me a few times after flashing factory images and a wipe in recovery always fixed it.
Just for future information: if at any time the device is stuck in a bootloop you can get it to robot into recovery by holding the power and volume down buttons for 10 seconds, or get it to boot into bootloader by holding power and volume up buttons for 10 seconds.

Thanks. Booting into stock recovery shows an exclamation sign with "no command", since I don't have TWRP anymore. Would I need to first flash TWRP before I can do a factory reset?
I just tried flashing to the same sock firmware as before the problem happened (7.1.2 N2G47W) but still same problem. I notice that after the Google logo disappears and the screen goes blank, the orange LED blinks 10 times before rebooting.
Edit: Tried factory resetting in stock recovery (by holding down power button and pressing vol+), the rebooting after factory reset. Still getting a boot loop.
OK I solved the problem. Apparently if you reboot after the flash, you need to disconnect the USB cable, else it will boot loop.

brother help me! i am facing same issue
first little info abt my device.
my device was running on android nougat with twrp recovery installed but the device was not rooted.
so get back to stock and install oreo I followed every step given on http://www.androidexplained.com/nexus-6p-revert-stock/ but somehow my phone is stuck at bootloop with no recovery installed.
Please help me here.
As per the Heisenberg guide, if you don't install root (SuperSU or Magisk), TWRP won't stick, so you'll go back to stock recovery.
For me, simply unplugging the USB cable after rebooting after a flash solved my problem. For some reason, if the cable is connected during reboot, it would boot loop.
brother, somehow I managed to install twrp. but everytime I touch it 2-3 times the phone gets switched off.
then it keeps rebooting to 'Google' logo.
can you tell me what should I do now?
@goister Hi how you manage to get to recovery when it's always stuck at the Google screen with no adb access. Please I am stuck there

Hello,
Previously I had flashed LineageOS v18 which had few bugs.
Then I flashed Android 10 official beta downloaded from Asus site (UL-ASUS_X00P-WW-AOSP-17.00.2003.23-user.zip).
Now I want to go back to another custom ROM but I am unable to boot into any recovery - stock recovery as well as TWRP.
- I have confirmed the bootloader is unlocked.
- Can't boot into stock recovery. Phone directly boots into OS.
- Tried "installing" TWRP in fastboot mode (fastboot flash recovery.img). Installation goes fine but when I reboot, the phone boots straight to OS instead of going into recovery.
- Tried "booting" TWRP in fastboot mode (fastboot boot recovery.img). Installation goes fine but when I reboot, the phone boots straight to OS instead of going into recovery.
- Tried both methods for booting into recovery (pressing the buttons as well as giving a command via fastboot).
Questions:
1. How can I boot into recovery?
2. If I can't boot into recovery, what can I do to flash a custom ROM?
