Nexus 9 update failure - Android Q&A, Help & Troubleshooting

I'm a newbie and trying to sort out my issue. I don't know all the tech jargon, so please consider that if replying.
Yesterday I okay-ed the latest update for our Nexus 9 - stock standard on Marshmallow. Got a persistent error "'Nfc stopped working" and neither the Ok nor the Report option would close the notification. I still could see the install update notice behind but couldn't access it. I tried booting in safe mode and briefly got the message the device was corrupt. When the safe mode boot was complete, the same error message still existed and I could not close the error notification.
I then tried a factory reset but now the device doesn't even get beyond the continually animated dots.
I found this post: http://forum.xda-developers.com/nexus-9/help/failed-marshmallow-update-stock-android-t3226704 and went through all the steps.
I tried to load this OTA:
6.0.1 (MMB29S) Link 59ab9d2ad432610244e54696775316cf fc7b590e6e6cbda6c1afdecfaed72a065359eeee
I verified the checksum on the download and all is good.
However, I can't get the update to load and this is what I get on screen:
Supported API: 3
Send package to device with adb sideload <filename> etc.
Finding update package
Opening update package
Verifying update package
E: Footer is wrong.
E: signature verification failed
Installation aborted.
At top of screen is this information:
Android Recovery
google/volantis/flounder
6.0.1/MMB29S/2489379
user/release-keys
use volume up/down and power
Then the menu
I am at a loss what to do now. The Tablet was bought through Google Play Store, so I can't even take it back to where I bought it.
Thanks
Greg

Update
Just to let anyone reading this thread that I contacted Google and they are replacing the tablet.

[Q] Can't boot after hard reset

Hi,
I've got a Legend on stock FroYo, which has never been rooted or had a custom ROM applied. It's been slowing down, so I did a hard reset using the Settings > SD Card and Storage > Factory Reset method.
Now, when it boots up, I get this message as soon as I unlock the screen:
Code:
The application Settings (process com.android.settings) has stopped unexpectedly. Please try again.
There's the usual [Force close] button. When I hit it, I get a black screen. The volume and power buttons work, but that's it.
I've gone into Recovery mode <3e>, and it give me this message in the bottom of the screen:
Code:
E:Can't open /cache/recovery/command
I've tried the "Wipe data/factory reset" option, and that didn't improve things. Same with wiping the cache.
I've also tried the "Apply sdcard:update.zip" option, and gives me these messages:
Code:
-- Install from sdcard...
Finding update package...
Opening update package...
Verifying update package...
E:failed to open /sdcard/update.zip (No such file or directory)
E:signature verification failed
Installation aborted.
So I guess I need to get a working ROM on my SD card and use that...but I haven't a clue how! Help!
BTW, I'm not a complete idiot. Although I've not really messed around with Android, I ran various custom ROMs on my old Windows phones.
If possible, I'd like to keep my phone "stock", but I'm happy to root it (etc.) -- at the moment it's just an expensive paperweight
Sorry if this has been asked before -- I've spent half an hour searching, but all the threads I could find concerned problems (and solutions) when dealing with rooted phones and/or custom ROMs.
Cheers,
Mahinda
hello, can you install the official ruu provided by htc again? i think the most up-to date one is obtainable from here: http://forum.xda-developers.com/showthread.php?t=1497357
but you might have to use another one in case your legend is branded. also see http://shipped-roms.com/index.php?category=android&model=Legend
Thanks!
I couldn't download the first one, as Mediafire's blocked at work, so I'm downloading a WWE version from shipped-roms.
My Legend's a replacement (under insurance after the first one got smashed), and I'm pretty sure it's unbranded. There's certainly no network lock on it.
I'm downloading HTC Sync too, as I think I need that installed on my PC...hopefully I won't need to do anything from the phone itself.
Will let you know how I get on...
So, I've managed to get it connecting to HTC Sync, which is nice.
However, when I run the RUU, it gets to the "Verifying information step" and then comes up with Error 170 -- USB Connection Error.
HTC Sync loses connection just before this happens, which seems suspicious. I've tried it on "Charge only" and "Disk drive" modes too, with no joy.
Having read up on the error, I'm now installing stuff on a cleaner PC so I can try again. It's Windows 7 though, which'll probably introduce exciting new problems
This is annoying. I'd deliberately never gone "off piste" with this phone (for the first time in years) to avoid this sort of thing.
hello, please try with htc sync version 2.0.33 and debug mode enabled in settings > applications > developement (in case you can still access it).
Downloading that now. I've tried:
HTC Sync 3.2.10
HTC Sync 2.0.25 (which was on my SD card)
RUU_Legend_HTC_WWE_1.31.405.5_R_Radio_47.26.35.04_7.05.35.26L_release_126592_signed.exe
RUU_Legend_HTC_WWE_2.03.405.3_Radio_47.39.35.09_7.08.35.21_release_130330_signed.exe
RUU_Legend_Froyo_S_HTC_WWE_3.15.405.3_Radio_47.51.35.17_7.13.35.05_release_160328_signed.exe
All on two PCs -- one running Win XP SP3 and the other on Win 7 Pro. I get error 170 every time.
It'll be late tonight before I try anything else. Got to go home and find my HTC Diamond!
Thanks for all the help.
Oh, and one more thing. I can't access anything on my phone except the lock screen. Thankfully, the little USB debug icon comes up, so I think it must be enabled already.

[Q] Phone auto shut-down for install, CWM aborts, endless loop

Hello,
My device is an HTC Inspire 4G running android 2.3.5 with cwm v5.8.1.5.
I just got my phone activate on straight talk wireless and within an hour of doing so, my phone alerted me there was an update to install, and needed to reboot.
The phone shuts off and then CWM pops up and tries to install the update, only to fail and give me a signature verification error, and an aborted install.
I figured no big deal, I'll just reboot and forget about it. Only now every time my phone boots up, it runs normally for a minute and then pops up the installation dialog and automatically shuts down, only to reboot into CWM for the install to abort again. Every time, without fail.
I am at a complete loss as to what to do about this. I can't find any information even remotely related to my problem. Maybe I just don't know the right string of keywords for the search. Anyway, any help will be immensely appreciated.
Update: I was able to recover an old image and at least make the phone useable again, but it's once again notified me that At&t has an update for me. I chose to postpone it this time, but I'm still at a loss as to how to handle this. I don't want to just keep clicking to postpone the update, but I can't allow it until I figure out why CWM is aborting the install.

[Q] Help, getting a 923 error.

Ever since I came back from the android m preview I have been having difficulty with Google apps. I have gotten error 923.
Timeline:
Flash M preview, have fun
Go back to 5.1.1
- this where I first got the 923 error and nothing would update it the Google play store. Also had WiFi connection issues.
Went all the way to 5.0.1 didn't see any issues
Tried uploading DU and its minimal gapps package.
- got a lot of Google apps error not working or something
- I think this is also where I got an error on initial setup saying "there's an internal problem with your device. Contact your manufacturer for details.
Back to 5.1.1 same issue error 923
Try the steps listed in this post:
http://forum.xda-developers.com/showthread.php?p=61433504
You only need to go up to step 5. The steps after that are just for installing DU.
(Oh, and you can ignore that warning message you get on boot. It's not important)

So plz any suggestions

I was just checking my mobile, all of sudden a message popped up saying '' Update ready to install" I read changelog and it said "new android version" I got so happy and as I am always connected to WiFi, It had been downloaded already so I clicked on it, it loaded onto installation mode it took 5minutes to install I was getting curious and finally it booted up, here is the disappointing part now, everything looked same, and after 15 seconds it said "failed to update". my question is that did anyone faced it too? I m already running latest colorOS 5.2. How did I got update message when there is no update published by realme 1? can someone please confirm me?
