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?

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.

Cannot install original firmware

Hello all,
Since my TF701T returned from RMA (touch screen issues), it has drained the battery like hell.
So I decided to flash original firmware again (done that before sending it), only to find out it now failed with this error:
Verifying update package...
E:failed to open /sdcard/T4_SDUPDATE.zip (No such file or directory)
So I renamed the zip to that file, but it didn't help.
This package is for "K00C" devices; this is a "tf701t"
In custom recovery log, one can find this:
ro.build.product=tf701t
ro.product.device=tf701t
Installed CWM, then flashed 2 custom ROMs (CROMbi KK and last AOKP), either system is stuck on boot or systemui fails permanently preventing using the tablet.
Then I flashed the original firmware with CWM instead of stock recovery, system stuck on boot-loop, except with 11.4.1.17, boot up but systemui fails again.
It's like the tablet Asus sent me back is not really a TF701T ?
Any help would be highly appreciated as the tablet is unusable at the moment, only boot-loader and stock/custom recovery are accessible.

Can you provide a logcat of the boot process from an adb connection please. Also the recovery.log from cwm (it's in /tmp/recovery.log so adb pull /tmp/recovery.log recovery.log)
It sounds like your system partition is not getting setup correctly or /data is corrupted somehow.
Also for stock you have to flash the zip inside the zip - you did do that right?

Let me get this straight:
You are on the 11.4.1.17 bootloader? That would mean you had the latest stock 4.4.2 firmware installed right?
The T4_SDUPDATE.zip is WW JB 4.3 firmware, is it not? You tried to flash that in stock recovery?
I read about one user who tried to downgrade from 4.4.2 to 4.3 yesterday and that also failed.
Another user contacted Asus support and they told him a downgrade is not possible from 4.4.2. No idea if that is true. The Asus reps are not always well informed....

Thanks for replying. Turns out I made a series of misleading mistake
First: custom recovery was installed, so it would not install an original firmware (device identifier incorrect, k00c while expecting tf701t).
Second: tried installing a custom ROM using Aroma, but the full wipe option didn't worked and ROM would boot loop!
Third: started using a modified ZIP of the original firmware without device identifier check, which was not allowed to install in stock recovery.
Bootloader was still on 10.26, however the closest thing to work was to flash original 11.4 firmware in CWM
At the end I use the original firmware ZIP and copied it to /sdcard/S4_SDUPDATE.zip, flashed stock recovery, and it installed flawlessly. That's when I realized the full wipe never occurred, all data where still there!

[Q] Help crash after flash

First of all sorry for my English...
Yesterday I was trying to install vanir room to my p880 after 10 hours I rooted the phone and unlock the bootloader then installed cwm but after reboot I get stuck on logo so I used kdz and load LGP880AT-00-V20a-262-000-MAR-26-2013+0 with (after 4 hours ) then i try using twrp and finally load the room (vanir_p880_4.4.4.112414.zip) and Gapps after rebooting I started getting crashes ( aosp keyboard, com.google, home and back buttons etc didn't work)
so again kdz then i try other room Paranoid but the same thing..
What I'm doing wrong? I used factory reset, wipe etc but same results

what gapps you flashed?

I don't really know what happened, did you successfully flashed kdz?
Where did you get it from? Here?: http://lg-phone-firmware.com/index.php?id_mod=15
Try to flash one of these (choose correct one for you)
Than you have to install recovery again.
But before that you can try to wipe /system, /data, /cache and then flash CM11 (I know it works without problems)
And I recommend you these Gapps: http://forum.xda-developers.com/showthread.php?t=2397942

well... yes i think I flashed kdz (LGFlashTool ?) I used kdz to recover my phone to original, I know my phone is Korean version and right now I use P88020A-EUR-XXX original firmware installed with kdz
What is CM11? and how i flash it?
so I have to root and unlock bootloader again and use twrp again right?

I think you should try with CWM first, get it: http://download2.clockworkmod.com/recoveries/recovery-clockwork-touch-6.0.4.5-p880.img
you can flash it with this app if you are rooted: https://play.google.com/store/apps/details?id=com.cgollner.flashify
then you can download CM11 from here: http://download.cyanogenmod.org/?device=p880
and gapps from last mine post
and then boot to recovery, do factory reset and wipe /system, then flash rom and gapps.
Hope it helps

Crash After Flash OTA Vanir 5.0
I had a similar experience. I was installing OTA latest update of Vanir...not realising that it was 5.0...a screen came up telling me that it needed to flash another recovery...not realising why it needed that, I ignored the request to flash. Of course, I then "bricked" the phone. I was able to install the original JB 4.12 (v20c) back onto the phone but now it won't root. I've tried almost every method in this forum to no avail.:
ADB just gives a message "error: closing" when I use the boot.exe method
o4xr method does nothing
all-in-one method also does nothing
ADB does recognise the device. Drivers are installed. Any help is welcome!

Have you tried to flash a recovery using fastboot? You won't need to root (if you are going to use a custom ROM) and/or it will be easier with a custom recovery

Soft brick after last update.
Hello,
I seem to have a similar problem. I updated a few days ago using Vanir updater. There were no warnings re updating the recovery, just a warning regarding losing root. I checked restore root. The phone rebooted to the bootloader logo, then to a black screen. Now, I can access Cyanogen recovery, SW update mode, abd fastboot mode using buttons and the recovery options. ADB can see the phone only in recovery mode, but not in fastboot or SW update mode. CM recovery has no option to mount USB storage, so my PC cannot see the phone, and I cannot side load a new recovery and flash a new ROM.
Is there any way to use ADB if it cannot see your phone in fastboot or SW mode? Perhaps modify the settings.secure string to enable ADB? ADB can see the phone in recovery mode.
Otherwise I will try flashing a stock ROM via KDZ or LG firmware update tool, the re-root and proceed - but rooting was a major ordeal the first time, so I would like to avoid doing that again.
Thanks in advance.

Error on installing ota 5.0.2 on Nexus 7

I got a NExus 7 wifi 2012 that was running 5.0. It was rooted, and used TWRP.
I got info about the updated and pressed install. Booted in to TWRP and nothing happened. I then pressed install in TWRP and in cache found the .zip and tried to install. Got an error.
I then booted in to android again, and flashed the stock recovery 5.0.2 (I guess it's like the stock 5.0?) and later I tried the OTA install again. Got an error.
I then read about the new "feature" in 5.0 about not allowing OTA if rooted, and I then in SuperSU completely uninstall the root and rebooted.
Later when I got the OTA update again, I thought it should work, but I still got the error.
What can I do? Right now I'm on a MAC. Can I in some way flash only the good stuff from the factory image, and in some way NOT have to factory reset the Nexus 7?
/Söder

Even when you unroot, your file system is tampered. Only way to update is using factory images.
I think you can flash the factory image without user data to prevent factory reset.

I managed to do this now to. My biggest problem is now to root the device again. I've switched back to stock recovery, before I removes root, when I was trying to apply the ota.
Now when I try to flash twrp recovery, I get an error about the size. I can flash the stock recovery though, the same way I flashed system.img and boot.img.
What can be wrong? I do I get root now again?

Yes, system, boot, recovery flashed with fastboot.
When in fastboot mode, I get error, something with size, when flashing twrp. I found a CWM recovery I could flash, but it didn't boot to recovery correctly.
The twrp file is not corrupt. Tried it again and also a different version.

OMG. I'm so f-ing stupid. Blaming all the x-mas food.
Was trying to flash the Oneplus One recovery. Not the one for Nexus 7.

[Q] [RESOLVED] Lollipop OTA update aborted

Hi all.
This is a moment that I'm disconnected hacks because I am in stock (6.0.401.11) and satisfied. I had OTA updates without problems until this kitkat version but today after receiving and downloading 2 times the OTA lollipop I can not install it because installation starts well and some moments later, the screen is stuck on the phone with red triangle and I have this in the recovery:
Verifying current system ...
"/ System / bin / reboot" has unexpected content
Installation aborted
Even when I do it manually, it's the same. Yet I have just manually switch successfully 6.0.401.12 that I missed somehow.
What's the trouble?

this says to me, in system/bin you have modified files, you must be 100% stock so flash TWRP recovery then use this: https://www.androidfilehost.com/?fid=95864024717072880 to retore full stock rom.
DO NOT try and root or anything, 100% pure stock required.
Full Reboot into android
boot back to recovery and flash this pre-load data here: https://www.androidfilehost.com/?fid=95864024717072879

You will need TWRP recovery for both of the above files, but you will also need to flash stock recovery afterwards to update which is here: https://www.androidfilehost.com/?fid=95864024717072472

Ok, thank you. But what I don't understand is that there's a long time I'm no more root, I'm full stock (Rom, recovery...), only S-off and Unlocked. So Why for previous OTA updates I have not had this problem? Why I have to manually update successfully from 6.09.401.11 version to 6.09.401.12 one? Why it is only the upgrade to the Lollipop which has problem?
What is the preload data? I already have this: https://www.androidfilehost.com/?w=...0f40a2a319761577a4c3f1e723594b05669cb009e9d00
Can I flash it and the stock recovery only?

Your problem is the lack or corruption of the file /bin/reboot
2 solutions:
Flash a custom recovery and reflash the rom
Flash a custom recovery and replace the file

preload data is HTC's little hidden way of stopping you getting OTA's if you unlock your bootloader, and yes it is required to update, without it, updates will fail.

Ah Ok I understand. These are applications that disappear when we unlock the bootloader. I had already installed them there's a long time. As I said my OTA updates passed without problem.

Problem flashing stock Rom in TWRP:
"- Zip signature verification failed
- Error flashing zip"
I don't understand anything, what's happen?

Problem solved and phone updated. Thank you!!!
