[Nexus 9 Q&A, Help & Troubleshooting] cam30era:
I don't think it will aid anyone. This requires TWRP recovery to work. Look at post #22....
[Nexus 9 Q&A, Help & Troubleshooting] Elina39:
I think, i'm not sure, but i think.. i might have accidentally done this..

My Nexus 9 was running TWRP, one of the latest versions, and cm 12.1.. i wanted to try reverting back to stock android, but in the process i think i might have made some fatal mistakes.. apparently though, when in the recovery mode ( not TWRP, since that keeps bootlooping. unless i press "factory reset" in recovery mode. ) it says my device state is unlocked.. the problem is just that i cant connect to my computer with adb or anything while in fastboot mode on my tablet.. so i cant flash anything ..

i was stupid enough to wipe my system and everything on my device, but that doesnt really matter since TWRP isnt working.

I would love to know if there is any kind of way i can get adb to work again? it really sucks having bricked my own device when i have no warranty.. x.x
[Nexus 9 Q&A, Help & Troubleshooting] jd1639:
If it says "unlocked" you probably are. Boot into the bootloader and first try

fastboot devices

Then

fastboot oem device-info

Flash a factory image and you should be good to go.
[Nexus 9 Q&A, Help & Troubleshooting] Elina39:
The problem is that I can't connect to adb when I'm in the bootloader.. s:

when I type "adb devices" nothing shows up.. x.x
[Nexus 9 Q&A, Help & Troubleshooting] Winesnob:
You can't use adb in the bootloader - this is fastboot mode. Type "fastboot devices" and you should see your device, assuming the fastboot drivers are installed.
[Nexus 9 Q&A, Help & Troubleshooting] djdole:
I was JUST in the EXACT same situation you were in.

I had previously OEM unlocked my n9, flashed marshmallow (all the images, including the vendor.img), and was stuck at the four-circle boot animation.

Thinking it was looping, I rebooted into fastboot and (stupidly) oem locked.

:(

Now I was in the same state that you were in...

The nexus 9 would boot loop into TWRP, with the "this is a development device not intended for production use" message, and being "locked" now, it no longer would allow me to fastboot flash anything, and the /data partition was unmountable.

Being able to get into TWRP was the first step.

If you go into ADB sideload in TWRP, and see that it can't mount /data THAT'S the first challenge.

How I got past it was to dig around in TWRP.

Specifically, there's a page within TWRP that allows you to format the data partition. DO IT.

Once that's done, you can mount /data within TWRP, and adb sideload will work again.

And if you reboot, it will get past the looping TWRP, into the marshmallow four-circle boot animation (which will still be bootlooping).

From here, download the unlockN9.img from this thread:

http://xdaforums.com/nexus-6/help/info-nexus-6-nexus-9-enable-oem-unlock-t3113539

And either follow the adb instructions on the thread,

OR (if adb doesn't work for you, like it doesn't me) use a micro USB OTG memory stick and TWRP's FileManager (having had mounted /data ) to copy the unlockN9.img into the /sdcard folder.

(I recomend one like this: http://amzn.to/1LMyGJA they're worth it for TWRP backups, and flashing zip files, or just copying files.)

Then either use adb to execute the dd script,

OR (again, if adb sucks...) use TWRP's terminal mode to execute:

dd if=/sdcard/unlockN9.img of=/dev/block/mmcblk0p27

(dd is an old unix/linux command, that also exists on Android devices)

Once you've executed the above dd command via adb or TWRP, reboot-bootloader, and execute your "fastboot oem unlock".

Follow the unlocking instructions (I believe it's just a press of volume-up), and reboot-bootloader, and you should see that your device is in an "unlocked" state!

:D

Now reflash everything. (I had to flash the stock recovery in order to get past the remaining bootloop)

From there, you're no longer bricked or looping!

[Nexus 9 Q&A, Help & Troubleshooting] kikemotions:
Ok, i had a similar situation, and after hours of reading and looking for an answer in forums, endup with this tutorial, that i published in the Google Forums.

The idea is to sideload an OTA Update without USB Debugging and with locked Bootloader. or you can sideload an Android N Update. https://plus.google.com/u/0/+ArtemRussakovskii/posts/K4oUnQymMqG

This is the tutorial

Ok i have a different question but i believe its still related as i owned OP3 i had flashed the community build and for that i had to unlock my bootloader with "enable OEM unlock" option enabled now i wanted to with this unlocked bootloader can i disable that "enable OEM unlock"?? so that in future even if my device gets stolen or lost the device will be rendered useless as the theif won't be able to flash due to that option being disabled
[Nexus 9 Q&A, Help & Troubleshooting] GedBlake:
Hi, samwidd...

I'm not familiar with the OP3, so the following guidance and advice is based only on my experiences with the Nexus 9.

--------------

If your bootloader is currently unlocked, disabling the "enable OEM unlock" setting won't make any difference. Because a potential thief could still run fastboot flash commands and reflash the device.

In order to prevent a thief from reflashing your device, three things are required...

--------------

1) The bootloader needs to be locked. This prevents the execution of fastboot flash commands.

2) The "enable OEM unlock" setting needs to be disabled, to prevent the bootloader from being unlocked in the first place.

3) A lock screen on the device, requiring a password, passphrase or lock pattern. This is to prevent Android from being booted (by a thief), such that the "enable OEM unlock setting" could be enabled.

--------------

Like all security provisions, all of the above is a double edged sword. If you're not careful, you can find yourself locked out of your own device... which isn't a good place to be???.

Hope this is useful to you.

Rgrds,

Ged.
[Nexus 9 Q&A, Help & Troubleshooting] samwidd:
So the best option would be

1) either relock bootloader each time after flashing a new rom or

2) keep twrp password protected and also disable usb debugging by default

So what do you suggest for me to be cautious in future 1st one or 2nd one as 1st one would be very mess as each time my user data will be deleted
[Nexus 9 Q&A, Help & Troubleshooting] LeoYL:
You can safely relock your phone's bootloader ONLY when the recovery on your phone can process "factory reset" command sent by bootloader. This is the reason why newer Nexus devices need to be in stock ROM when they are being relocked, since the stock recovery can process the factory reset command during relocking process, whereas TWRP can't.

Therefore, if TWRP on your OP3 can boot and perform factory reset if you order fastboot to erase your phone, you may relock your device safely and keep using TWRP to flash third-party ROMs. However, remember that some devices may require unlocked bootloader status to boot third-party ROMs.

There is a common misconception on USB debugging. Neither adb feature in recovery nor fastboot in bootloader require USB debugging in Android system to be switched on . The only way to prevent others flashing your phone is limiting recovery's functionality (like using a password protection, or using stock recovery, which can flash nothing but official ROM) AND locking the bootloader. Even if you use password to protect TWRP, others can still bypass it by flashing another recovery or deleting files in your internal storage (depends on the mechanism of TWRP password lock you want to use).

I don't have an OP3 either, so all above is based on my experience on my Nexus 9, Galaxy S4 and Xperia Z1. Operate bootloader on your own risk. Keep in mind that tampering and customizing your device's software decreases security to some extent, no matter how well you intend to protect your device.
[Nexus 9 Q&A, Help & Troubleshooting] GedBlake:
Hi, samwidd...

There's a common misconception that USB debugging has any relevance with regard to running fastboot flash commands.

It doesn't. It makes no difference if its enabled or disabled when it comes to running fastboot flash commands.

USB debugging disabled just blocks the execution of ADB command lines (eg, adb push when copying something from a PC to an Android device.)

So USB debugging disabled or not, a potential thief would still be able to reflash a stolen device.

-----------------

Although I use TWRP myself on my various devices, I've never set a password on it, so I am not 100% certain on this following point... but I suspect even with a TWRP password thus set, a thief could just fastboot reflash TWRP or some other custom recovery.

-----------------

The only real, certain, sure fire way of protecting your device from being reflashed, is to relock the bootloader, disable the 'Allow OEM unlock' setting and set a secure lock screen in Android as I've alluded to in my previous post.

But as you mention, re-locking and unlocking the bootloader every time you wish to fastboot flash something would be a bit of a nuisance, as doing so performs a factory reset of the device.

-----------------

What it all boils down to in the end, is it's a trade off between security and convenience.

You can have one or the other... but not both.

Security=Locked bootloader

Convenience=Unlocked bootloader

And you have to make the choice as to which is more important to you.

Hope this helps.

Rgrds,

Ged.

I've just locked my bootloader on my Xiaomi device without knowing it will work. Then I rebooted my phone to see if it was locked. It was locked but now it failed to start the android successfully.

I then used the Mi Flash Unlock tool to unlock the bootloader once again. What I'm getting to is that, there should be an Unlock Tool for you somewhere on the internet, maybe Google created one for you already.
[Nexus 9 Q&A, Help & Troubleshooting] madbat99:
If the os won't boot, there is no way to tick "allow oem unlocking" in developer settings. Pretty sure that's the issue here. There are full OTA update images now that can be sideloaded to help with this issue.

This is not a xiaomi device, what works for one device, does not mean it does for any others. Nice try though.

I kept getting the BSOD ( blue screen of death) and even went back to the ATT Store and swapped my SM-907A for another one and it blue screened in under an hour. I called Samsung and they said they had defective motherboards. He mad up a ticket for me and I am sending it out to them before work in the AM. The ATT Store said they would return it for me with a 10% restocking fee. Really??? Whatever I really like the tablet and it was the last one available in the area so I decided to send it out to Samsung to replace the motherboard. A guy in another thread said he did this and now the tablet is 100%!!! SO anyone else have issues with these????

SM-P907A. Galaxy Note Pro problems

I am having issues with my AT&T galaxy note Pro SM-907A. Screen will actually flicker, then reboot. It will continue to keep rebooting like a bootloop almost. Everything is stock, I am not , rooted YET and have never tripped knox. (I dont want to give AT&T or Samsung any reason to say this is my fault for something I did to the tablet.) It started doing this at 20 % battery life and starts having issues around 45%. . It will stop doing this and actually stay on and operate correctly as soon as I plug it in to charge. There have been some instances where I see the battery start to get low, plug it in to charge, turn it off and literally 5 or 10 minutes later my battery shows to be at almost full charge. I really like the tablet and have had it as soon as it was released by AT&T. I was persuaded into ATT's next plan, which Iis a completely different story. But I dont feel like I should have to stay committed to the contract on the Next plan paying full price for tablet if they cant provide a fully operational tablet.

You believe it to be heat related? I have played games, nothing too intense. I have however had it get quite hot, I was using it in my office the other day and when I went to use the screen I noticed it was very hot. I was listening to a podcast so hadn't touched it for a couple hours and didn't realize it was getting hit by direct midday sun. I experienced no issues and it was very hot, the hottest I've ever had any of my devices get. It was similar to how my phone gets when plugged in and in the dock in the car during summer.

Flickering issue solved!

Try this at your own RISK!!

I recently solved flickering issue to my note 12.2 P900 wifi version.

I'd had to open the back cover.

The battery pushes on the cable for both the screen and wifi cable.

I raised the motherboard up with a thin piece of plastic sheet and

problem solved!

I had no warranty so I went ahead to do it.

The flickering solved. No flicking with Full brightness even when battery was 10%.

I did this after I replaced my Lcd cable from ebay seller.. so its the battery casing

pushing the Lcd cable connection to the motherboard.

Hope it helps someone as I have found no solution to this anywhere.

developer option, resetting ... none helped.

Last time they replaced the LCD. They expedited the service, so once they receive my tablet, they guarantee 3-5 days in their hands, then send back to me.

$900 tablet, sent it twice in less than a month. I should've waited for the nexus 9 lte!!!!
