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.

Problems Rooting XT1068 retgb

Hi all,
I'm trying to root my UK XT1068 (5.0.2) with retgb firmware. I tried CF Autoroot first, but that wasn't working because there is no retgb download image. So then I thought I would try to manually unlock the bootloader and flash TWRP then install a custom pre rooted rom. I unlocked the bootloader fine, and flashed TWRP successfully, but when I navigate to 'recovery' in the bootloader I just get a no command error. I tried installing CWM too, but I just get the same result. What am I doing wrong? All I want is to root my phone
Thanks in advance!

I ran twrp 2.8.4.0 recovery via fastboot and then flashed superSU 1.8.4. Once booted up with root I installed flashify and flashed twrp to recovery. I think SuperSU changed the flash stock recovery file with bak so that it did not reflash stock recovery on reboots

Is it the Motorola website that says your boot loader cannot be unlocked, or the command line output when you request OEM data?

[Q] HELP!! (D415) Soft bricked after installing xposed framework for lollipop!

After doing the xposed lollipop rom update for armv7 for my LG optimus l90 and I flashed it using twrp...... my phone rebooted like normal but once it got to T-mobile it got stuck there so I booted in twrp custom recovery mode and wipe the dalvik cache and the data. That did not work so I did a factory reset, now everytime I try to boot my phone it shows the LG logo and boots into recovery mode!! I don't have access to download mode because I unlocked the bootloader with this link: http://forum.xda-developers.com/lg-l90/general/guide-unlock-bootloader-t-mobile-l90-t2836457
So I only have access to Recovery mode (it is stock recovery though because I did a format through stock Recovery) (yes I have SD card) and fastboot!!
Does anyone else know how to fix this?? I think I might but I don't know where to get stock lg roms that are zip files and I can only get .kdz for the LG flash tool, but I cannot use that because I don't have Download mode.
Please help! Also I do not have root permissions anymore, so If there is a way to gain root through Recovery or Fastboot for this device that would be great!

Anyone? please?

Sorry it took so long to respond, hopefully you fixed the issue but you will need to obtain a computer with flash tool and required componets installed and SDK tools, you have the chance to use the "fastboot oem unlock" to unlock bootloader then "fastboot flash .img recover" or you could "fastboot flash laf.img laf" to restor laf.img to use download mode then to enter it and restore to KDZ

[NEED HELP] I need help. and will deletehis asap

i have a symphony roar a50 (Bangladesh). it was running everything stock and updated with twrp 2.8.7.0 without root. bootloader was unlocked.
i was trying to root the device with the AIO from this thread:
http://forum.xda-developers.com/cro.../android-one-toolkit-unlocks-relocks-t3294448
the phone suddenly rebooted in the middle of the process and was stuck in a bootloop. i tried to factory reset it but it still didn't work. was still on boot loop.
then i tried to flash the appropriate stock firmware but that didn't help it wont boot. stuck on the boot logo for 1.5 hrs. then tried CM13 nightlies and the cyanpop roms. still nothing.
i am currently in a state of shock as this is a fairly a new phone and i am to travel to Chittagong in ~11 hours.
please help

don't you take a backup ?
and don't you wipe every thing before flashing the cm13 ?

I too Had the same Problem once as I Tried Rooting My Android One through the same method as u did, So for fixing it I prefer that U FLASH The Stock MM ROM for Ur Device through STOCK Recovery ( Remember to Wipe Cache and Data b4 Flashing ) AND then ur Device mst be Fixed ( This method worked for me ) And Dude if u want to root Ur Device Follow This Method : -
1) FLASH TWRP RECOVERY
2) Reboot into Recovery and FLASH Thunderzap 5.1 Kernel through Recovery
3) Then FLASH SUPERSU ZIP from Recovery
4) Reboot And Done ! Ur Device is Rooted ! ?

3) Once Drivers are installed Download ADB AND FASTBOOT from here http://drive.google.com/file/d/0B1nu6Ydzrmi-dWdmS00tWjE1WHM
4)Extract the zip and open the folder and then HOLD SHIFT+Right Click and then click on Open Command Window here

6) DONE ! STOCK RECOVERY IS FLASHED and Remember to keep Stock Recovery img file in the ADB AND FASTBOOT FOLDER

Thanks I'll try this asap currently on a train..

Okay.. I've shipped it to the customer care. They said I'll have to wait 3 days for it to get back. I'll report back then.
Thank you everyone for your input.

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
