[Q] RED exclamation mark! OTA doesn't work - One (M8) Q&A, Help & Troubleshooting

I have this version on my m8: 1.54.206.5 and wanted to install the OTA update, but when my phone boots into recovery it shows me a red exclamation mark.
I had TWRP recovery but flashed the stock recovery for 1.54.206.5 and uninstalled xposed framework but I can't install the OTA update...
How can I solve this problem?

[Q] Cant access Recovery

Hi,
I am having a bit of a problem with my Desire. I attempted to upgrade from Oxygen v2.0 RC3 to RC4 using the Oxygen updater.
When the phone rebooted to install the update I got a picture of the desire with a red triangle and a exclamation mark. I have tried booting directly into recovery but I get the same red triangle.
Using ROM manager I tried to flash ClockworkMod recovery but I still get the red triangle. I have tried using unrevoked to flash ClockworkMod and AmonRA but have the same problem.
Any assistance would be great!
Thanks!

Red Triangle OTA update

Hi,
I had stock 4.4.4 on my phone with unlocked bootloader and rooted with custom recovery, i got the recovery notification so i flashed using fastboot stock recovery since flashing of OTA needs stock recovery but everytime it updates into recovery, it will start the update install with the green synch icon and then after like 3 mins i get a red triangle with exclamation mark. What is going wrong here?

That's your stock recovery. Press both volume buttons + power to get to your recovery menu.
Let me try that, thank you

[Q] How to update?

I got the notification about the 5.1 OTA update on my Nexus 7 2013, downloads fine, but can't install because I have TWRP and a custom kernel. What should I do to update it?
EDIT: so I flashed the stock recovery with Wug's root toolkit, and tried to install it again. When I press the button to reboot and install the update, it gives just an error message and a picture of an android laying on his back with a red exclamation mark
What else should I do?
Turns out that with Wug's toolkit the stock recovery will not install, this is the actual problem, is there any other way to get back the stock recovery?
Flash the update from /cache
I tried it but won't install.
It says: E: Error executing updater binary in zip ' /cache/update.zip'
Under the advanced options you should be able to flash the stock recovery if that's what you want to do.
scrosler has a pre-rooted stock 5.1 TWRP-flashable ROM and a flashable bootloader zip. I just flashed those and everything is working fine.

I'm going to add onto this question. OTA update won't work for me. The red android comes up.
I had flashed android 5 with wugfresh, rooted, unlocked bootloader. I don't think I modified the system after that. I tried to unroot and flash stock recovery and bootloader. No change to the OTA failure.
I see that there was a bug with the 2012 nexus 7 bootloader that would cause this. Google coincidentally just updated that bootloader, perhaps to fix said problem. But I'm not sure what to do about my particular 2013 razor/flo problem.
Does anyone know how to get OTA updates working with a stock rom you flashed yourself?
Edit: Wugfresh says it is impossible to OTA update a rooted android 5 lollipop device? http://forum.xda-developers.com/showpost.php?p=60262545&postcount=1072
Edit 2: I unrooted but that still didn't work. To workaround, I extracted system.img from the factory image zip for the same version of the OS I currently have. Then I wrote that image to the system partition using the universal android toolkit img flash feature (#11.). The system and data seemed identical upon boot. Now the OTA update will work naturally. But this has all been very confusing! Many mixed messages were found by google searching.

Android 6.0 and Recovery

So I flashed the factory 6.0 image from Google and noticed I can't get into the stock recovery, I just get the android logo with exclamation mark. When I flash TWRP using fastboot TWRP works with no problems.
I just use TWRP to root and like to restore stock recovery.
Anyone know what I'm missing?
