Hi, I literally opened the nexus 9 out of the box, powered it on & after choosing a wifi network it began updating, the device crashed during this update and now it won't boot! I've tried & searched for everything, anyone have any ideas?
Booting to recovery with HW buttons, wiping cache/userdata/factory reset - Nada!
Can boot into fastboot, no permission to flash as oem unlock is disabled!
I cant get into the tablet to unlock fastboot oem unlock within devOpitons or usb debugging etc, (com.android.phone has stopped on boot) black screen indefinitely.
I can't flash any images while it is locked
surely there must be a simple method?
desperate here
Return it
I'd just return it. I'm no expert, but I'd seek a way to avoid the update during setup and try to postpone it until you unlock developer options and OEM unlock. I'm not sure how you'd bypass the update during setup, but you're in the right place if it's possible.

Certainly it can. If it started to install the 5.0.2 OTA, there have been a lot of bricks.

Welcome. And FWIW: there's a button for that.
If I remember correctly you can still flash the stock images even with the boot loader locked. Its only custom images that google will not accept unless you unlock boot loader.

Bootloader has to be unlocked to "fastboot flash" anything.
You can sideload an OTA with a locked bootloader, but you have to be able to access recovery.

Indeed I'm still new to nexus devices. I've been flashing on Samsung devices for years so I'm still stuck in my Odin ways. Just got the N9 less then a week ago. The whole fastboot thing was foreign at first but I'm getting there lol. Thank you again.
I've recently unlocked my bootloader and I wanted to re lock it. Well, I couldn't find any thread about this and I thought it would be good to open one. My question is obviously how to re lock the bootloader in Xiaomi Redmi Note 3 Snapdragon.

Did you use unofficial bootloader unlock? If you did, you're really really f***ed right now. The only way to fix this is to physically open the device, unscrew the motherboard, plug in the usb and use a metal object to connect the two "testpoints", which will force the phone into edl mode.

In that case of official unlock, guess you can take to service center and get it repaired?
For unofficial unlock, there is simple way to lock bootloader by putting back original "emmc_appsboot.mbn" from fastboot rom.
fastboot flash aboot emmc_appsboot.mbn
fastboot flash abootbak emmc_appsboot.mbn

Yep, still bricked. Hard Bricked. I have used tespoint again but it was actually hard to trigger it because it caused phone to restart normally instead of going to edl.
When I tried to EDL Flash my phone normally when i had access to android, I got and max memory something problem in Mi Flash and when i tried again it sent a hello package to my phone and then it said catastrophic failure. So, don't know what that actually means and I hope not what it actually says. However i still have access to fastboot mode and recovery mode but i found out that I actually have locked bootloader after flashing this "emmc_appsboot.mbn" and had the phone alive in chinese dev rom and then i wanted to roll back to global stable via edl and got brick. Sadly I do not have access to this test mode where you test your phone's sensors, display and more.

Hey, you can go into EDL mode?
If yes, why don't you flash the Fastboot ROM - Global one if you don't want CHinese one
Refer this post for basic steps.

Great! Happy to note that your phone is back.. If flash has been successful then it will work.
testpoint is risky and requires expertise right?

Actually it is not that difficult but it is extremely tricky since if you press only the left one test point it will just reboot. You need to touch them at the same time. Although you'll need to be accommodated with electronics since they are sensitive.

I had a little heart attack because I thought That i had cut the Button Cable during the flash process but THANK GOD it was right underneath the motherboard and IT NOW WORKS. YES I AM IN MIUI GLOBAL. THANK GOD. Just for you to know, every failed bootloader unlock on any smartphone is equal to several heart attacks.
Hello,
situation ist this:
Cyanogen Recovery is installed and there is no rom on the phone. But it won't install a new one through apply update. So I tried installing twrp through fast boot. But it failed with:
FAILED (remote: Device not unlocked cannot flash or erase)
So i tried to unlock it which gave me:
FAILED (remote: oem unlock is disabled)
oem devices gave me tampered = false and unlocked = false
What can I do.
Would appreciate help
Morishno
Flash stock recovery and try unlock again.
Dumb Question but how exactly do I do that?
Just flash it via fast boot? And where do i get it?

You dont need to be sorry, thats okay i jus asked... Maybe OP didnt enable oem unlocking.
I didnt enable oem unlocking because it wasnt necessary. The device was unlocked and twrp and cyanogenmod were installed. But somehow cyanogen recovery was installed. Super user was away and I tried to reinstall it. Not knowing the recovery had changed I chose twrp/cwm to install it what resulted in a boot loop. No problem I thought just flash a ROM which didn't worked. No problem just flash a proper recovery it didn't worked. And somehow the device is locked again..
Sorry I was little brief when I said flash stock recovery. I believe if you revert back completely stock you can start the process from the beginning again. That would mean fastboot flash stock recovery then any firmware of OnePlus X. I'm not sure how a bootloader can relock itself.

But I couldn't flash twrp.. Is it possible to flash the stock recovery with a locked boot loader? I don't have access to the phone at the moment and i want to gather as much information possible thats why i'm asking

Found a hard brick guide. You mean that?
So I just remembered something was able to help someone else with a similar issue. If you can boot Into something and your rooted download the app Rashr. With it you can flash stock recovery and be back in business.
The problem is i dont have anything to Boot
//UPDATE: So I tried booting with fastboot boot but it said cannot boot device isn't unlocked.
Edited
So i managed to save the Phone using the Hard Brick Guide. Thanks everyone!
Thank goodness for the hard brick guide. ?

So, long story short, I recently bought a Nexus 9 from ebay which arrived with factory reset protection.
I have spoken to both Google and HTC about the situation and both were of no real help except for saying a few things outright between them to give me good enough reason to believe one of two things.
That 1 - it is possible to flash factory images over a device with a locked bootloader
or 2 - it is possible to unlock the bootloader without having access to developer settings
Anyone have any experience with either of these possibilities?
https://developers.google.com/android/ota
Full OTA Images can be flashed onto devices with locked boot loaders.
You need to boot into recovery and select sideload update.
Yeah, I know how to do that, but that only goes for updates, doesn't it? I tried to sideload a previous build onto the tablet but it failed the procedure, so it doesn't really solve the issue and if I flash a more recent update I still get FRP :/ If I wanted to revert back to the 7.0, or even marshmallow, would that be possible? Or does that require an unlocked bootloader?

Those are full ota images, same as factory image. Meaning full package.

Ah yes, now I see your predicament. Unfortunately, there is no "there" there. You do need an unlocked bootloader to wipe the system clean with a factory image, and as you noted, the Full OTA Image will recover you from a system that won't boot, but it won't get rid of FRP.

did we ever fix this? my bootloader is locked and no os installed. Was trying to return to factory and went thru all the flashing steps successfully then at the end locked the bootloader. Now tablet says "for development purposes only not for production use" and boots back to fastboot. It will not reboot at all

Never found out how they do this.... are you able to boot in to recovery? if you can do that you may be able to flash a recovery OTA through 'apply update from ADB'. Worth a shot

it's only a bad move if you make a mistake and can't repair it because your bootloader is now locked. But if it goes well then you're all set.
anybody seen this error? I was trying to revert back to stock. Once it rebooted, this happen. I found an old thread but only resolution was to warranty it. Of course this device is old so no more warranty. wanted to see if theres other solutions before i dump it on ebay for parts..

You tried to relock the bootloader didn't you? Usually not a good idea. Is it not booting anymore? If it boots go in developer options and tick the allow OEM unlocking back to on. And then see if unlocking the bootloader changes it.
