Got the 5.0.1 notification but...

Well I am surprised I received the 5.0.1 update notification but after agreeing and letting device restart, it didn't happen and device claims that is up to date and still on 5.0
Did Google retired the OTA?

Your not alone im having the same issue. My 6 is on verizon and the same issue has happened that you described. Cleared data in the frame service. Phone claims up to date...still 5.0

Darn it....
At least AT&T and Verizon respect the "direct updates form Google" advantage of the Nexus brand.

Anyone able to help?

If you've flashed a custom recovery and/or are rooted, the OTA will fail. It will just reboot without doing anything, then the OTA disappears when back in Android and autoupdate says you're up to date.
You can download the image from the Nexus factory images site, extract the system and radio images, and flash them yourself with either fastboot or Nexus Root Toolkit.
This post gave me the idea:
http://forum.xda-developers.com/showpost.php?p=57411133&postcount=75
And here's the link to the latest N6 image from Google:
https://dl.google.com/dl/android/aosp/shamu-lrx22c-factory-ff173fc6.tgz
You'll need WinRAR or similar to extract the download from Google.

It failed for me too, bone stock. Connect your phone to a charger . it reappear and I was able to update

Dxtra i have tried this and it has yet to reappear how long has it taken for you to see it repop

Same here.... Verizon/Stock Nexus 6. Mine didn't even reboot. After I chose to accept the update, screen just flashed to up-to-date. Now claiming up-to-date each time.

Strange I'm in the UK and have the exact same problem. Got a notification thru last night for the 5.0.1 update, decided to leave it until this morning and it's gone. Must be something to do with Google.....

I am bone stock and have the same issue . Last night it said there was a new update and I said ok lets do it.. It said it was going to restart and then it never restarted or nothing and says its up to date even though its on 5.0 . I am on verizon !!!

Immediately. I guess I was lucky

I did not root/installed custom ROM neither, which boost the upset. But again, I am glad that I should not worry for update delays due the device being from a carrier's branded, and evidently I am not the only one, I will give Google the opportunity before opting for manually flash the update which that means dealing with an 20+ GB backup first.

Question
Hey i was wondering, I got my OTA update last night and of course my phone is unlocked and rooted but i still attempted to download and install it. I was successful in downloading the update and my device rebooted. I shortly got the error message so i rebooted the device and when i logged back on i was still on 5.0 and the OTA notification is now gone.
My question is, since i downloaded 5.0.1 and the device rebooted in the attempt to complete the install will this now cause my phone to no longer get the 5.0.1 update notification? I plan on unrooting once i get the notification so i can go ahead and OTA and when that is completed root the phone again. Or am I now forced to flash a factory reset in order to get that OTA update again?
ideally i would prefer to wait for the OTA so i dont have to factory reset.

I had this disappearing 5.01 update issue as well. I figured I'd grab the OTA and adb sideload load as I had in the past. However, I've found that I can't get the device to go into Recovery mode at all. Power and Volume+ at the robot with the red exclamation triangle yields nothing. Perhaps the reason the update didn't happen is because the update itself couldn't activate Recovery either.

Once you're in the recovery screen, make sure you are holding the power button first, then clicking volume up. If you hit them at the same time it doesn't work.

Do I need to be rooted to flash update? On my one plus I could download update and the go to recovery and flash it.

AT&T Tab S 8.4 - SM-T707A Lollipop upgrade released

Hey all,
Thought I'd let those of you that have an AT&T Tab S 8.4 know that Lollipop has been released today. Happened to be on the AT&T Software update page here: http://www.att.com/esupport/softwareUpdateArticle.jsp?sid=KB425812&cv=820 and noticed it listed the update.
Manually checked for updates on my tablet, it's downloading now. My 8.4 on AT&T is totally stock.

Downloading now... 1.1GB

manually checking shows nothing for me

Mine wasn't too laggy after the upgrade. But as I know from places like XDA usually a very good idea to do a full system wipe which I did.
What I am most thankful for is there is now an option to remove that Samsung screen that has those Samsung widgets that go full page. Can't recall what it is called. Yeah I know could have got rid of that using a 3rd party launcher in 4.4 but so happy Samsung put option there to disable it finally. To get rid of it, long press blank space like you were going to add a widget, then click Home Screen Settings, then uncheck "Content Home Screen".

Has anyone who rooted with kingroot updated? I'm assuming it'll kill root, just curious if I need to unroot prior, or if the update will still install. I'll post the answer tomorrow after I update.
I've had some Samsung devices which will update while rooted, and some that will not.

I'm rooted with Kingroot and it's currently downloading the update. If you load Xposed Framework and Wanam Xposed, under Security hacks there's a setting for Fake System Status that allows you to set it to Original.
I'll follow up when the download finishes.
Update: The download completed but the install failed and then got stuck in a boot loop. Ended up having to go to the Samsung place at Best Buy to have them re-flash KitKat. Now the tab is telling me I have to wait 24 hours to check for updates. I'm sure everything will be good now that I'm back on a factory image.

Turn off automatic date and time and manually advance it by a day, and try again.
When they re-flashed KitKat did it wipe your tablet? The OTA failed me when rooted, failed me after un-installing adaway and un-rooting and removing KingUser. I cannot do a firmware upgrade via Kies 3 as it's not available. I cannot do an emergency firmware recover via Kies 3 as it's not soft bricked. I can't find either the KitKat or the Lollipop firmwares online anywhere... Currently I have a tablet, works fine, I did a factory reset (in the back of my mind knew this wouldn't work) that has a custom status and won't take the OTA.
If anyone knows where I can find the KitKat firmware, or the OTA, please let me know.
Or maybe someone could grab the OTA off their tablet after downloading prior to updating and share the wealth with the community???

Has any kingroot user tried triangle away, unroot via kinguser, and take the OTA?
Also just realized that if I can fail the OTA, I can obviously download it... Where do I grab it from if I wanted to flash it with odin or sideload?

OTA came down successfully while not rooted. The reflash at Best Buy didn't wipe it.
As far as I know, the factory images for the AT&T versions aren't available anywhere, or at least I've been unable to find them. They obviously exist because I'm pretty sure the guy at Best Buy used Kies to flash with an image that's available to him from Samsung.

I re-rooted last night in the attempt of using triangle away to clear customs status, then un-rooting. This was odd because device status still shows custom but download mode shows official and Knox is 0.
While I was briefly rooted again I downloaded the OTA in the hopes of copying it to my PC and updating via ADB Sideload... Couldn't find it. If anyone knows where Samsung puts these I'll grab it and post it to share.

im not rooted, performed a factory reset, and my device still doesn't see any updates. Can somebody provide a link to the ROM?

The OTA gets downloaded to /cache. If you are rooted you can see it. But the OTA is not a complete ROM, just a differential to the ROM you have.

Turns out there is a imei problem with the tablet that is preventing the download. My imei number is paired with a IPhone 4. Anyway will take a few day to fix then the upgrade should work.

I get the same. I wiped my device hoping for a different outcome, and still no update.

I found this in the thread below.
It is an old tread but I'll comment anyway. SM-T807 is the 3G version while SM-T805 is the LTE version. Both Hardware (CPU/GPU) and comms modules are different. So 805 LTE (which has Lollipop) firmware won't work for 807 (no Lollipop is currently available nor Samsung plans to release soon).

John.

After not being able to take the OTA after rooting, even after un rooting, not being able to find the OTA and sideload (not in /cache), and not able use Kies or Odin I finally took it to the Samsung kiosk at my bestbuy.
They reflashed 4.4.2, didn't wipe anything, and immediately downloaded and successfully installed the lollipop update after getting home and on WiFi.
Just don't mention that you rooted ;')

5.1.1 update keeps failing

I have tried twice now to update my phone to the new 5.1.1 update. Each time it downloads. I tell the phone to restart. When it goes to install it states Error. Then just reboots with out doing the update. No information what is causing the issue.
Now after this 2nd time my phone is stating I have to wait 17 hours to check again to try the update! No idea what is causing it to fail. Wondering if anyone else has had this issue. If not I am thinking tonight I might do a clean wipe of my phone and restart.

If your rooted or where rooted it will fail the update...have to odin back to stock first

Same issue here. After reboot the install fails. Have never rooted this phone.

Quoted from the Android Police article "As mentioned, I could not get my personal AT&T S6 to install the update. I finally got it to work after enabling all the system apps that I had disabled before trying to do it. I have seen others report success with this as well. If you have already tried and failed, just manually set your date a day ahead to check the servers for the OTA again."

Update notification of marshmallow but no installation??

Hi,
I'm French and I 'very got a stock nexus 6.
I have the 5.1.1 android (LMY48T) and as I noticed a notification about 6.0 I started the update.
After few minutes, the update was DLed and a rebootr was announced... But nothing.
I waited for a bit.
And tried to shut-off the phone for a manual reboot... Now I'm still in 5.1.1, and when I check the update it's says that my phone is up-to-date..
Any help?
Thanks for reading.

Happened to me too on my Nexus 6

Thanks for the contribution, did you find any piece of information anywhere else?

no not at all :/

Bummer...

hello gregaste
i can confirm the exact same problem downloaded the ota and pressed restart and install and nothing happened it its telling me ur device is up to date ! i hope somone can help us

Are you rooted? Not sure what "very stock" means. OTAs will fail if you are.

Had the same thing happen to me. Twice. Got a replacement N6 last week and I was letting all the OTAs go through before unlocking the bootloader and rooting. When I got the 6.0 update notification I let it download. After rebooting it didn't update and when I checked system update it saif I was up to date despite still being on 5.1.1. Then, for fun, after returning my original Nexus to stock I decided to let the 6.0 update download. After rebooting I was still on 5.1.1 and again it said I was up to date. Very weird. I got impatient and flashed the factory images.

I'm stock, and i'm not sure about my first message, but I'm positive that "very stock" is an auto-correct fail...
I phone to Google android help yesterday, and a guy told me something like "s-h1t happens" more polite though, and that I should wait for another notification... let's hope.

Happened to me as well. Once the ota is downloaded, give time to the phone to restart itself in recovery, it takes about 10 mintutes to go into recovery and dont interfere with soft reset.

That may have been the October security download. After getting Marshmallow on my N5 and N9 weeks before, I got that update notice, downloaded it, rebooted and noticed the old Lollypop boot animation. I thought the update didn't get applied and never got another notification. I later ran Stagefright Detector and noticed that the two latest CVEs were remediated. So I'm still waiting for Android 6 for my Nexus 6.

I went from LYZ28J to LYZ28K with that update. I believe T-Mobile and Sprint are on different forks of Lollypop.

Why is my Nexus 6 not receiving updates?

I've just taken my phone out of box, this is October 2015, and the moment I opened the phone first it started overheating and second I checked for updates and it says "software upto date".
The software is stuck at 5.0 and I don't know why I'm not receiving a single update when it's the time people are getting Android M. I've a Nexus 5 too and it's up to date to Marshmallow while this one is still stuck at 5.0 Lollipop.
I guess this has got to do something with the OTA feature and I want to fix this instead of flashing OS manually. So please tell me what to do now.
Till now after many Google searches I did twice reset of my phone and cleared data cache everything of Google Services Framework, but still nothing is helping.
Just 1 day old nonrooted nothing ever did, everything's from my side fine, just not understanding what to do.
Please please help me soon, I'm regretting buying nexus 6 now!

I've already mentioned while others are at 6.0, I'm not going anywhere ahead of 5.0
Please help!

Where did you buy your phone from? Are you sure it is not running a custom ROM? Is the bootloader locked?
Keep the phone connected to the internet (WiFi or cellular data), and sign into your Google Account, and wait another day. It may take a day or two to get update notification.
Edit - depending on your build#, you can download the OTA files and sideload them using ADB (don't need to unlock bootloader if that is a concern), or the faster option would be to just unlock the bootloader, and flash the latest factory image.

im on my 3rd day on my nexus.. but im not losing hope.. im still waiting for the ota.. its on 5.1 lmy47d...

So here is something funny. I was waiting and waiting for 6.0 on my nexus 6 for days. Never came. I have friends that have the same phone on the same carrier and they had already received their updates. So frustration and being impatient had gotten the best of me and I decided i was going to side load the update. In order to do so you need to unlock the boot loader which will wipe all of your data, EVERYTHING. When the phone rebooted completely wiped i went through the initial set up and it wasn't 5 min later the 6.0 update came rolling in like no big deal. WTF. I don't know why it wouldn't find it on its own but i wouldn't. Needless to day that is what I did and ended up getting it in a round about way. Maybe give that a try if you get to impatient and at that point if it doesn't show up just side load it. Hope this helps

Same, stuck on 5.1 LMY47D

google gives us factory images for a reason. if you arent patient enough to wait for an ota, just flash a factory image yourself, instead of starting threads about how you arent getting an ota. whats the point of a thread about you not getting an ota?

Sideloading the OTA using "ADB sideload" doesn't require you to unlock the bootloader.
Unlocking the bootloader is needed if you choose to flash the factory image file instead of the OTA file

Well I'm damn impatient, if I'd 5.1.1 and waited for 6.0 I'd have definitely had some patience, but waiting from 5.0 doesn't make sense.
Anyways to the point, after listening to your story, I tried same thing, clearing cache and reset from recovery mode, but still it didn't help
Hope there's some other resolution to this now.

I suspect it was your post that I responded to, at another forum - but you have two options really
1. Unlock bootloader (wipes data), and flash latest image
2. ADB Sideload OTAs one after the other in the right sequence (see http://forum.xda-developers.com/nexus-6/general/ref-nexus-6-stock-ota-urls-t2906493 for OTA URLs) - check your current build and choose a path to get to the build you want

I am having the same problem.
