So I have my bootloader unlocked, but for some reason I can't flash a recovery (CWM or TWRP). I've tried to flash recovery through fastboot using adb fastboot commands, mfastboot commands, and mototool aio. I've also tried to flash recovery through rom manager and rashr. ( I am rooted )
cmd: getvar:max-download--size
cmd: download:007b1800
cmd: flash:recovery
mismatched partition size (recovery)

Click to collapse
I get
Boot up failed

Click to collapse
Whenever trying to enter recovery afterwards. I get the warning bootloader unlocked motorolla screen for .1s before going back to fastboot.
Can anyone point me towards what I should be doing please? Thank you
Is the phone being detected when you type "adb devices" in cmd window ?
If not you need to install correct and drivers, then in while in the boot loader type "fastboot flash recovery RECOVERYNAME.img" obviously you change it to your Recovery's image file and it has to be in the directory with adb and fastboot of course.

Yes it is, it is detected as the phone boots ( it still boots to the stock rom ) and detected in fastboot as w ell.
edit:
to clarify, this is on 4.4.3 if it matters

I guess I didn't look up as well as I should have. So even with an unlocked bootloader, there are no recoveries out for 4.4.3 ?

Yeah, of course there are recoveries for 4.4.3/4.4.4. Try to flash another recovery bro

I've tried like 5 recoveries so far. i just tried cwm 6.0.4.5 and now i can't even get into the bootloader, (adb reboot recovery, as well as holding recovery keys at phone turn on) just goes into the rom now. Does it sound like i have to recover everything to stock now?
Not sure that it matters, but I am rooted if that helps or gives you ideas for any other options
edit: through rom manager i was able to reflash the latest CWM and now i have bootloader access back. I still can't get into any recovery though.

You can try to go back to stock, and after, flash a custom recovery and see what happens

Ok, I guess I'll try that tomorrow. The thing I'm wondering is, If it doesn't work flashing through fastboot, outside of the ROM, how would reverting back to stock help at all? A stock flash shouldn't change the bootloader at all?

I am not responsible if anything goes wrong.
Post any questions here: [Q&A][ROOT] Root for SHIELD Tablet 2.0 (Lollipop)
Pre-requisites:
Already flashed OTA 2.0 (Unless bootloader is locked in which case read instructions for locked bootloader.)
Unlocked bootloader and flashed CWM from here
SuperSu zip file from here
PC with working adb and fastboot
Instructions (Unlocked bootloader):
Reboot tablet into recovery mode
Code:
adb reboot recovery
Flash SuperSu zip file with CWM
Reboot tablet
If CWM asks to fix root, say yes.
Profit.
Optional Reinstall CWM (The OTA removes it)
Flash via fastboot
Code:
fastboot flash recovery recovery.img
May need to flash a couple of times to get it to stick.
Reboot tablet
Instructions (Locked bootloader):
Download update but DO NOT UPDATE YET
Gain root on previous build via towel root.
Flash CWM from link in prereqs via Flashify
In CWM choose update from zip and choose the zip file in the bottom of your 'nvidia' folder on your internal storage (/sdcard/). DO NOT REBOOT
Flash SuperSu zip file with CWM
Reboot tablet
Don't reboot if you want to reinstall CWM below
Profit.
Optional Reinstall CWM
Copy CWM to root of internal storage
Code:
adb push recovery.img /sdcard/
Flash via adb shell
Code:
adb shell
mount /data
dd if=/data/media/0/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS
If the mount commands errors with device or resource busy just skip it and move on.
Reboot tablet
that was quick, thanks!
worked perfectly on Shield Tablet WiFi (LRX21M) with unlocked bootloader.
Thanks for the guide. Hopefully this is just me being stupid, but I ran into some issues following the guide. I rooted via TowelRoot, and then downloaded the OTA without flashing it. After using Flashify to install the CWM image, and installing the OTA via CWM, I'm unable to boot into the recovery image anymore. I can't boot into it through the hardware key combo, and I can't boot into it through ADB.
I'm following the locked bootloader steps, if it helps.
Edit: Nevermind, unlocked the Bootloader is by far the easiest option.

What is happening instead of it booting?

it boots to the old "android on it's back with the red triangle icon" screen. It appears that installing the OTA overwrites the recovery image.

Fantastic. Working on it
Pretty much this.
Ok I think I fixed the locked instructions
What about if we had already updated to L, but had never unlocked the bootloader? I was rooted before with towel root, but never actually unlocked boot. Does the unlocking method still work? Or am I SOL for now?

Yes the unlocking method still works. It is not an exploit it is officially "supported" by Nvidia. See here
As mentioned below unlocking will wipe all data.

I don't think it should be any different. They didn't encrypt it or anything. Unlocking should be possible with just doing an oem unlock. Of course this will wipe your data, so be sure to do a backup.
For the "locked" method, you might want to suggest re-flashing CWM recovery (if desired) afterwards. The partition name is SOS.

I'm having the same problem just flashing the recovery. Fastboot says it flashed ok, but when I reboot into recovery I get the android on his back with the red triangle.

I assume you are using the unlocked instructions? Try flashing it a couple of times. Mine was doing the same thing at first. You can also try the CWM flashing instructions for locked as that may "stick" better.
Thanks for the method, worked fine - WIFI version.

Can you get into the fastboot menu (hold volume down and then power) or into the recovery (from the fastboot menu)? Also, have you unlocked the bootloader and/or flashed a rom?

Did you try flashing recovery from fastboot mode? If not, try following the instructions on the TWRP website (minus the "adb reboot bootloader" part, of course).

Did you try flashing the kernel? I can verify that the Optimus kernel and the TWRP from the Multirom thread work, so I'd recommend trying that combination.

The MultiROM TWRP itself doesn't install multirom, I just know it works, while some other recovery images don't. You will be able to flash a different recovery once you fix your problem.
I forgot that a kernel can't be readily flashed via fastboot... You should try downloading a stock firmware package and flashing at least boot and system.

I didnt get anything from the post. you have to be little bit specific.
i mean you
1. unlocked bootloader(fine)
2. installed twrp(also fine)
3. installed cm13(great)
4. you reverted back to stock rom??? How from twrp, flashfire or fastboot.?
and now how are you trying to install twrp? from fastboot?
Flash twrp image with fastboot, start TWRP, reboot recovery within TWRP, then twrp sticks... profit.

TWRP is not sticking...
1) Start the bootloader, flash TWRP in fastboot with the command: fastboot flash recovery twrp.img (Replace twrp.img with the name of the TWRP img file)
2) Press VOL DN to start Recovery and select it, TWRP should start... When prompted if you should allow changes to system, say YES or allow or whatever so that is allowed to mount system as read-write.
3) In the TWRP main menu, select Reboot, then Reboot - Recovery
4) The device will restart and TWRP will start again, if asked to allow changed changes to system again, allow it
5) Go to Mounts and make sure Mount System Read-Only is NOT ticked
6) Press Home, then Reboot and Reboot Recovery again
TWRP will start again and be set, it will not go away unless you flash something with a recovery.img in the file (custom ROMs do not normally contain this file).

At what point? What command are you using to perform the flash?
I'm sorry... I've just done this on numerous G3's and what you are describing doesn't just happen for no reason... either the initial flash was done incorrectly, the process to set it was not followed, or there is actually a defect in the device (which is unlikely if TWRP boots even once after bring flashed).

NEVER USE KINGROOT OR KINGOROOT on a Moto G3 with Marshmallow, it will soft brick... We have seen at least a half dozen specific examples by experienced users... Somehow you got lucky, but I would never recommend this method to a user.
Now, once rooted Flashify is a viable option.
Hello,
Sorry for this post but i have a real problem !
I have install a twrp and root my phone for flash rom but now i have factory rest and haven't any OS...
