Fastboot Boot Recovery.IMG not Working after Update

I have been using "fastboot boot recovery.img" to load into TWRP after OTA updates to load SuperSU as I am only rooted using the stock ROM. However, after this recent update (2.16.651.4) that includes the WiFi Calling and Android 4.4.3, when I run the command it just causes the phone to reboot. It does not reboot into TWRP, which is my recovery.img file.
I found a Nexus thread talking about having to add a kernel command line for the Nexus after a certain version of hboot, so I am not sure if it is related.
Does anyone know how to fastboot boot now with the latest update? I would like to avoid replacing my stock recovery with TWRP and just continue to boot into it. Alternatively, is there any other way to install supersu?
Thank you,
Ben

As a quick work around flash twrp onto the device, once done with it then flash the factory recovery back, Also check to make sure your bootloader didn't relock after update.
stock recovery from the update.

Thank you for the reply. I thought about taking that approach, but I was really hoping someone would have an answer on why the procedure wasn't working now. My bootloader is still unlocked.
I found this as an approach someone did on the Nexus 4 for a similar issue:
fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img
Thoughts?

nfinitefx45:
I did just now flash TWRP into recovery, loaded SuperSU, and then flashed your recovery.img back to the phone. So thank you very much for the recovery.img.
I'd still like to know if fastboot boot can still work, and also if there is a way in the future I can get my own recovery.img (possibly back it up before taking an OTA)?

not sure about the fastboot issue, but to backup your recovery any time just go to adb and type the following
adb shell
su
dd if=/dev/block/mmcblk0p43 of=/sdcard2/recovery.img
this will copy your recovery to the external sdcard

Thank you for those steps. I do not have an external SD card installed, so I modified it to store the recovery.img on sdcard instead.
Now I can always fastboot flash twrp and then back to stock recovery.
Thank you again!

You would need root to do this. Not being able to use "fastboot boot" you would just be backing up the flashed recovery. Possibly towel root temp root, but I would assume it has been patched in newest update.

So I am S-On with a non-HK M8
I was on stock rooted 4.4.2 and I flashed the stock recovery and took the OTA
Now I am on 4.4.3 and still have SuperSU installed (not rooted)
Everything is working fine, but when I try to boot to recovery i get the red triangle with the !
Any suggestions?

That's the stock recovery. Did you ever flash a custom recovery back on after the OTA?

I am s-on & unlocked but i was able to flash the stock recovery from sd card to take the ota.
Is it possible to flash twrp back in the same way?

Yes, after the OTA, just flash TWRP back through fastboot and then re-flash SuperSU to get root back.

I just applied the update released today, and I tried to save the recovery.img file before flashing TWRP. However, it kept giving me permission denied. Do you have the recovery.img file from the update released today so I can use it for the next update?

What's the output in the terminal when you fastboot flash recovery?

rooting problem
It doesn't show any error as such.
In the command window it shows successful.
But when I click on recovery it reboots back to fast boot.
Like for a second it shows the screen which reads 'this build is only for developers'
But then instead of opening Twrp it reboots back to fast boot.

Hi,
you can try this:
Copy the downloaded recovery image (.img file) to the folder where you have placed your ADB and Fastboot.
Launch terminal (or command prompt on Windows).
Navigate to the directory where you have placed the ADB, Fastboot and .img file together.
Shut down your phone and reboot into boot loader. For nexus devices, simply hold volume down + power to start up the phone.
Connect your phone to your computer.
On terminal (or command prompt) window, write fastboot boot <img file name>, e.g. fastboot boot twrp.img.
Your phone will restart and will boot into the recovery mode.
Hint:
use adb reboot bootloader in CM13 to reboot into fastboot bootloader

You have flashed a recovery image to your boot partition, so it always boots to recovery. You need to flash a boot image to the boot partition.
But why do you want recovery if you won't flash anything to your phone?
By flashing recovery, you are doing exactly that anyway.
You have an unlocked bootloader, so you may as well flash an advanced stock kernel. It is stock kernel with twrp built into the boot.img. Check android development section.

thank you
since i know that i can't boot recovery without flashing, i have no other option as to flash.
can't i flash it to FOTA partition?
i have 10.7.A.0.222 firmware and need root access but like to do it manually

You can't boot directly to FOTA on XZ. Need modified boot.img or flash twrp to boot (like you did before). Then while in TWRP, flash Supersu.zip to get root. Afterwards flash kernel only in flashtool to get stock boot back

Recovery restore after CM 14.1

Hello,
I had flashed Cyanogenmod 14.1 on my Xperia T. It has removed my recovery partition and installed cyanogenmod recovery together with system.
Actually I want to switch to LineageOS 14.1, but I got no recovery. CM recovery says signature verification failed...
What i've done was to flash TWRP into boot using fastboot, then I booted it up and flashed LineageOS.
I forgotten about GApps and looks like there is no way to flash them w/o recovery.
I could of course flash TWRP once again into boot and reflash Lineageos with gapps once again.
Anyway, I would like to restore recovery...
Any ideas how to do that?
fastboot flash recovery says there is no such partition.

TO replacing Stock Cyanogen Recovery to TWRP:
