Nexus 9 corrupt after android update

DEL 707 · 16 Dec 2015 at 00:08

I did an android update on my Nexus 9 today, however after the update it sat at the google screen for well over an hour.

I turned it off then back on, but now I get this message.

Visit this link on another device:
g.co/ABH

How do I go about fixing this? This tablet is my 1st android device and I have very little experience.

Have you tried visiting g.co/ABH? You will have to use another device other than the Nexus 9, of course.

Have you modified it at all? Root etc

Nope not touched it at all.

Tried to do a factory restore today while at work, it spent ages "erasing" then went back to the same crash loop.

Going to this link: https://support.google.com/nexus/answer/6185381?p=verified_boot&rd=1

Apparently it should go away after 10 seconds.

If it doesn't, and you don't mind losing your files, you can reflash the stock image with this: https://developers.google.com/android/nexus/images?hl=en

Thanks for that link, but I'm confused.

I've got the tablet connected up, and gone into Fastboot, but I don't know how to open up a terminal.

Need ADB Drivers setup first. Id look up on XDA "Return nexus 9 to stock/unbrick" ull find something similar which will help u out

Installed ADB, ran adb devices, but it does see anything. Even though my PC see's it connected as Android 1.0.

I also downloaded SDK and used it to download the Google USB driver, but I've still got nothing.

If you've gone into fastboot, adb won't do anything, you need fastboot.exe

Orcvader · 16 Dec 2015 at 22:40

Depending on what ADB pack you installed it may have fastboot as well, do the command:

Code:

fastboot devices

And see if it can see the device then.

Well I've tried fastboot and I get this.

C:\adb>fastboot devices
HT4CXJT01334 fastboot

C:\adb>fastboot oem unlock
...
(bootloader) ability is 0
(bootloader) Permission denied for this command!
OKAY [ 0.008s]

Haven't messed with a Nexus device in a long while but if flashing the stock image you may not need to unlock the bootloader. Unpackage the tgz file you downloaded, then unpackage the tar file, and there should be a flash-all file you just click and it will do all the work for you.

You need to have enabled it in developer options, which would involve booting the phone

DEL 707 · 17 Dec 2015 at 09:22

I can't boot the tablet though...

Thanks, I'll give it a go when I get home tonight.

You need to have unlocked the bootloader before you can do that unfortunately.

I threw in the towel, took it back and got a replacement.

Spent the last hour or so doing all the updates, fingers crossed this time.
