Hi,
I followed this article -> phandroid DOT com/2014/11/05/how-to-root-nexus-9/ (Sorry, new account, can't link) to the letter, and everything seemed to go well, until the last step where I ran "fastboot reboot" which returned "error: device not found" I thought nothing of this as there was a reboot option on the devices screen, so I rebooted, I get the google logo, followed by the four orbs, then it says "Optimising app x of 99" once this is done, its back to the orbs again and it just repeats.
I tried restoring to factory defaults from the recovery menu, that did nothing, then sometime after I noticed I actually cant turn the device off any more, if I hold the power button it turns off, but reboots instantly. I tried going through the steps again, but no luck, the only change was that I didn't have the error at the end, and the first Optimising dialogue said 104 apps, not 99, but all the rest afterwards have said 99.
I'm not sure what do do from here, any advice?
Here's my cmd output:

Try returning to stock and trying again. See method 2 of this, http://forum.xda-developers.com/showthread.php?p=58956577

That root method is for the old 5.0 Android; it doesn't work anymore with 5.1.1. Go back to stock using jd1639's link, then run Chainfire's Auto-root and you should be good to go. Link is here: https://download.chainfire.eu/595/CF-Root/CF-Auto-Root/CF-Auto-Root-flounder-volantis-nexus9.zip. There's supposedly an update coming in the next week or so to fix the stagefright vulnerability, make sure you do NOT take it in case it does weird things that could cause you to lose root.
(I know it says Volantis and not flounder but the Nexus 9 is known by both names, just to keep things confusing)
Thanks guys, root is now all working
Had a strange way of getting there though, I went back to stock, then tried the auto root as mentioned, but I had the same problem again, so I re-flashed just the boot.img file from stock, powered up, and lo and behold, root working fine

Your better off doing the bootloader unlock, then flashing TWRP recovery, then flashing supersu. IMO using autoroot methods make no sense. You now have no recovery and if anything goes wrong you have to flash all of the factory images again. And what if you want to use a custom rom? I would highly recommend getting TWRP at http://twrp.me and flashing it. Then you can actually make full backups in case of disaster. Good luck!

Hey, to unlock bootloader you enable developer settings in android, check the "enable oem unlock" switch, boot the device into fastboot mode "adb reboot fastboot" and issue "fastboot oem unlock". This is assuming you have adb and fastboot in your path/working folder. Then, download the lastest twrp - flounder-2.8.7.0.img - and "fastboot flash recovery flounder-2.8.7.0.img". The flounder version of twrp works for both LTE and WIFI variants. If you need any more assistance just let me know.

Hi,
After upgrading the device to 3.1.3 the device is draining very fast and I didn't like the new changes.
Can anyone please share steps to downgrade the device to 2.2.2 OS?
I think it's easy, but somebody pls CMIIW, just flash the official TWRP via fastboot (prior to v41), reboot to TWRP, wipe cache, data, system, dalvik, and flash the OOS 2.2.2 zip file.

Thanks for your reply
I'm not familiar with few acronyms(CMIIW, TWRP). Could you please elaborate with steps?
Any reference link would also help.
No need to twrp.
Just reboot to recovery, wipe all tehn flash full 2.2.3 full rom zip.
you'll loose your settings and apps installed of course
NB : I think you should wait that 3.1.3 stabilize itself. What don't you like in OOS 3? All tastes exist, I know, but I can't see the point here....

ok, I will try this step. If I go to recovery and do I need to download the rom or is it already there?
OOS 3 is buggy and draining out the battery of my device. Also, its making the device very slow.

No, you have to download it and put it in your device.
With a well parametred OOS 3 , my device never flyed so quickly.
You should start by going to apps, menus then reset apps parameters (there is a menu for that).
You can go to storage, click on internal storage and wipe cache data.
Reboot.
If still the same, instead of going backward, reflash full rom 3.1.3 zip
the best way to do it is flash bluSpark's TWRP, and then flash OOS 2.2.2

You should add that an unlocked bootloader is mandatory for that.
Be carefull, a lot of people (mainly the one that rooted via Kingroot) wiped theirs devices, going that way, without knowing it.
Hey there,

Fastboot flash original stock recovery then 2.2.2. Bootloader downgraded and can continue flashing as normal.
thanks for that fast reply! i am now happy on "twrp-3.0.2-0-onyx.img" (recovery) and "cm-13.0-ZNH5Y-20160925-STABLE-Sultan-onyx.zip" (rom).

How my unlock has been lost ? My phone is yet rooted. SuperSu works correctly.
Can you tell me how it is possible to lost twrp ? I have never upgrade since my unlock.
And now, my only solution is to do a 'fastboot oem unlock' and lost my data ?
Thank you
Not sure whats going on there but easy way is to fastboot flash old stock recovery. Then install 3.1.3 with no problems. Rename file and delete .tar .
Your device bootloader is locked.
Why do you want to flash old TWRP.
To install OOS 3.1.3, you should better flash old OOS stock recovery.
But not sure it wil work.
Now, when you try to reboot recovery, on what recovery are you?
Always TWRP? None?
You should flash Oxygen one, so you can try to flash OOS 2.2.3 full rom zip to start.

Thanks for answers.
The issue is exactly that:
"Now, when you try to reboot recovery, on what recovery are you?"
I boot on stock recovery... oxygen recovery instead of twrp. Why?? How??
However I had flash my recovery with twrp last months ago and root my phone.
My problem is I do not want to lost my data... Indeed I can unlock again bootloader but all data will be lost.
How could you flash TWRP if your bootloader is locked? :-S
I don't think you ever get re-locked upon any update..
And yes, you probably have to unlock boot and lose all your user data.. Unless you don't have a backup handy of course :I
You can flash oos 3.1.1 through stock recovery no matter if your bootloader locked or unlocked.
Just download the full rom zip of oos 3.1.1 and place this zip in internal storage and flash with stock recovery. After installing oos3.1.1 you can backup your data and after that you have to go to the developer settings and allow the OEM Unlocking and now you can follow same procedure to unlock bootloader.
Everytime I type the command 'fastboot oem unlock', the screen says;
OKAY [ 0.002s]

but then when I want to flash a recovery it says;

Have you tried just flashing stock recovery? Does it say that for everything you try and flash? A lot of people are trying these shortcuts to try and upgrade bootloader. Though most can work the safest bet is to flash original stock recovery and upgrade from there. You might be looking at going through the hard brick guide.
seems like you locked the bootloader while you are rooted...iam stack on same step too...

Fastboot oem unlock>fastboot reboot>doesn't ask about wiping
I've followed every tutorial they all say that after requesting oem unlock, you can verify the unlock was successful with fastboot oem devices-info> device tampered-false, device unlock-true, then fastboot reboot> system reboot, but it does NOT ask to wipe the data. Am I missing something?

My bootloader is unlocked. I used LG Bridge to update to 20A. Now I cannot get root back. I boot into fastboot. Flashing TWRP seems to work, but I cannot get into it. I'm aware that I have to boot directly into TWRP after flashing for it to stick (or it will be overwritten with stock recovery). I've tried fastboot commands to boot (see below). I've also tried the volume down button combo to boot to recovery, which gets me to the prompts about erasing data, but No exits and Yes prompts x 2 never boots to TWRP. It doesn't load it at all. I've re-downloaded TWRP to be sure I didn't have a bad file.

So flash recovery and remove the battery and boot by following steps
1. Press and hold (at the same time) the Power and the Volume Down buttons until the LG Logo is being displayed on your G5
2. Next, release the power button for only a moment and then press it again (keep holding)
3. Keep pressing the buttons until the recovery mode menu is displayed
4. Answer both questions with "YES" (no worry won't reset your phone as described) and then TWRP should boot
5. Now swipe to allow modifications in TWRP
Bonus step:
6. Format DATA partition (note format not wipe) and flash SuperSU

Thanks. I was aware of the clicking YES twice, but when I do that, it never gets to TWRP. That was the behavior before my new issue (noted above, showing questionable bootloader unlock).
your bootloader is already unlocked
why do you try to flash unlock again?
anyway, the key combination should work
just tested...
you just have to get the proper timing
using a H850 variant

I agree that it SHOULD work, and yet it doesn't. It isn't a timing issue--I get to the wipe data prompts and click yes, but it doesn't load into TWRP after that. I'm doing this immediately after flashing recovery per the instructions.

That is because the kernel and boot loader used for 14.1 is different you need to update the kernel.
Follow Mega unbrick guide carefully to unbrick the phone.

I had same issue you need to flash different TWRP. If your on 2.X.X TWRP 3.0.2 . If you have updated to 3.X.X then 3.0.3. If you have issues with 3.0.3 you can try twrp 3.0.2-0 or bluesparks 3.0.2-1 V41.
just flash the arsenic-kernel everything will be fine.. https://forum.xda-developers.com/oneplus-x/development/kernel-arsenic-kernel-r2-t3422020
The problem is not the kernel but the bootloader so how to change/update recovery?

If you did not unlocked bootloader properly then also you might face the problem...
to unlock bootloader: https://forum.xda-developers.com/oneplus-x/general/discussion-how-to-root-oneplus-x-t3242830
make sure you follow all the step. (If you didn't followed these steps then lock bootloader {fastboot oem lock} and unlock using this mathod.)

I used to have this problem. You need to flash the new bootloader, sometimes updates and whatnot doesn't flash it for you. If the zip doesn't work you can try finding the fastboot partition image and flashing to aboot (instead of fastboot flash recovery recovery.img when flashing a twrp build for example, it would be fastboot flash aboot emmc_appsboot.mbn). There was a post on the oneplus forums where the files could be found, just google dtb not found error.
