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
I decided to unroot my S4 seeing as though a rom I had flashed was screwing around with my system. I eventually was able to flash a stock rom via kies, but now the phone is stuck at the boot screen (Samsung logo with blue light).
I have tried booting into recovery mode, but for some reason after 5 seconds, it just ignores it and goes into standard boot, something that it has done since I flashed the bad rom.
Would anyone know a fix for this?
Thanks in advance.
An update. I managed to get into recovery mode but instead of the normal android with the blue square, the android is on the ground with a red triangle. I've wiped cache and data, but still getting stuck at the boot screen.
Some help would be appreciated.

There is a 50/50 chance that if you go back into twrp/cwm custom recovery
and do a "factory reset" it would boot up normally unless you also wiped
"system".
Good luck!

Flash a stock firmware using odin in download mode then see if it reboots
If not go to stock recovery after that factory reset and wipe cache reboot
Well, while trying to flash a custom rom on my phone I ended up here and tried many different methods.
First after I installed TWRP on the phone I tried to install the rom and it told me it failed. So then I wiped my phone and tried again, still failed. Then I got stuck in a bootloop. I did a factory reset and was able to get into TWRP. So I wiped everything and it asked me if I wanted to root my phone. I said yes and now the boot screen stays forever and the notification led never turns off. So I did factory reset and tried to run a command on terminal "dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota" it still did not boot up.
I have tried flashes the stock and I can't get oceanhost.eu and storagecow.eu to load up.
Please I would appreciate any help, is my phone dead? I can always boot to TWRP as long as I factory reset.

Sorry that I didn't mention this but, I am runnning a LGG2 802 16gb
Hi all!
Yesterday i tried to update my twrp to a new version. I flashed it in twrp and everyting went well i thought.
So when the phone rebooted i get a second of a red blinking light then a black screen. So i restarted it again and it get in to the phone. I downloaded twrp from the offical app in playstore and tried to flash it from there. Same thing, a second of a red light that blinked then the black screen.
So now i have tried to get he phone in fastboot mode and my phone response to the adb commando, adb reboot bootloader and the phone reboots but then again it just reboots to my ROM again. I cant reboot to the bootloader mode.
I have installed all the drivers that is necesarry, but still it dosent work. Also, i have tried to flash the twrp file in adb toolkit for my Axon 7.
What can i do?
EDIT:
Its solved! I downloaded another twrp file, a older version then i got twrp back
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?
