I think the ota hasn't really rolled out yet ,most of us running 5.1 flashed the stock image [emoji29]
[Nexus 6  General] EmperorX:
So this is probably a dumb question... But is it possible to downgrade via OTA (without wiping). I'm on T-Mobile and currently on the D build. Now that the OTA is officially going out (M), I know I can just wait for someone to capture it, but am just more curious than anything.

Thanks!
[Nexus 6  General] NastyNeil:
I'm wondering the same thing. I'm in the same boat.
[Nexus 6  General] cam30era:
[MENTION=5371055]NastyNeil[/MENTION],

Not via OTA. But if your bootloader is unlocked, you can fastboot flash the 5.0.1 factory image.
[Nexus 6  General] EmperorX:
Ok great, thanks! I do not wish to wipe my device so I will wait for someone to capture the OTA.

Thanks again!
[Nexus 6  General] NastyNeil:
Can that be done on a Mac? I don't own a PC.
[Nexus 6  General] david279:
fastboot works on a mac using the Terminal app
[Nexus 6  General] cam30era:
I believe so. But you'll have to do your research. And don't expect a lot of support around here. Almost non existent in this community.
[Nexus 6  General] NastyNeil:
Thank you!

Anyone with a Motorola purchased N6 on Verizon 100% stock (locked and not rooted) get a 5.1 OTA yet?
[Nexus 6  General] eng_saad:
Hi,

I have a problem after updating to 5.1 [OTA], where I can't boot the device in Recovery mode or bootloader which is the same of the following picture [the picture for nexus 5]

[IMG="http://i.ytimg.com/vi/mHJV_UprpE8/maxresdefault.jpg"]http://i.ytimg.com/vi/mHJV_UprpE8/maxresdefault.jpg[/IMG]

Can any one help me to reset the phone and restore the bootloader and the recovery mode?a
[Nexus 6  General] :
Not sure what your problem is exactly but did you press volume up and power when dead Android appears? That'd be the way to get to recovery. What about ADB commands also?
[Nexus 6  General] ooofest:
That describes me, answer is sadly no.

Wonder if we'll get the D or E build, though I suspect the former from other reports I've read.

- ooofest
[Nexus 6  General] HankStorm:
I don't have a need to unlock or root right now and don't want to screw up my ability to get future OTA's by installing the wrong one via ADB. Guess I'll just have to be patient.
[Nexus 6  General] gee2012:
The latest LMY47E is a official Google N6 image which you can flash and still receive OTA`s afterwards. Need a unlocked bootloader though and enable oem-unlock in developer options.
[Nexus 6  General] Ricardovet83:
No 5.1 here, problem?

Hi, i'm still waiting to receive the 5.1 OTA. I have a XT1103 unlocked.

When i turned on the nexus for the first time, i received the update 5.0.1, but nothing about 5.1 here. It is my 5th nexus device, but i usually received the OTA in 3 or 5 days after the roll out starts.

Have some problem? Somebody received the OTA 5.1? I don't want to manually update....

Thank you :good:
[Nexus 6  General] Mista513:
Same issue as EmperorX, I side loaded the global D 5.1 update but want to side load the M update. I can't side load it over the D version correct? I don't want to wipe my device and the bootloader is still locked.
[Nexus 6  General] :
OTA roll out can take 2 to 3 weeks to complete so hang in there. Otherwise, sideloading is easy enough.
[Nexus 6  General] :
I'm kind of curious about this as well.
[Nexus 6  General] Ricardovet83:
Bus i can side load in a macbook? Have a tutorial for this here?
[Nexus 6  General] Shrek77:
Since the OTA for 5.1 M is out http://www.androidpolice.com/2015/0...gs-android-5-1-ota-roundup-for-nexus-devices/ Can I sideload 5.1 M over 5.1 D without fastboot and unlocking the boot loader like I did to get to 5.1 D?
[Nexus 6  General] :
I believe you will have to be familiar with using terminal commands. I'm not a Mac user so look here:

http://m.androidcentral.com/how-manually-upgrade-your-nexus#slide2

Read the first part about using Android SDK and getting set up. OEM unlock not needed if 100% stock and just sideloading OTA. Read the last page for sideloading instructions and commands.
[Nexus 6  General] hondajohn88:
If you've just update via OTA, the stock recovery will be in place and you've lost root.

To put custom recovery on (TWRP) do this (assuming you have installed Android SDK and have fastboot and ADB installed. Instructions to do so are at https://developer.android.com/sdk/installing/index.html and install the Stand Alone SDK Tools):

1) Download latest SuperSU and copy it over to your phone. http://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip

2) Download latest TWRP recovery from http://techerrata.com/browse/twrp2/shamu and move the file to the location where the SDK tools have put the Fastboot and ADB files.

3) Put your phone in fastboot mode

4) Connect your phone to your PC via USB cable.

5) Open Command Prompt window and navigate to the folder where Fastboot and TWRP image files are

6) In the command prompt window type "fastboot flash recovery openrecovery-twrp-2.8.5.0-shamu.img and then press Enter

7) Boot your phone into Recovery mode and tap Mount and ensure System is checked. If it isn't, tap it to put the X in the box next to it.

8) Tap Install and navigate to the location where UPDATE-SuperSU-v2.46.zip is then tap that file and swipe the bar to install it.

9) Reboot your phone and it should be rooted with custom recovery installed

Post #3 updated with simple ADB sideload instructions.
[Nexus 6  General] NastyNeil:
That will only work when updating from 5.0.1 to 5.1 correct?
[Nexus 6  General] :
This is the method that is always used.
[Nexus 6  General] NastyNeil:
I understand that, I just meant this won't work going from 5.1 build D to 5.1 build M. Correct.
[Nexus 6  General] :
If an OTA zip is made available that flashes D to M, then yes this method will work. As of right now, I don't think there is one available yet.
[Nexus 6  General] bajasur:
Can modems be flashed in recovery with nexus? I know this was not possible with Samsung devices and required and Odin flash
[Nexus 6  General] efrant:
If a modem came as part of an OTA update, then yes it can be flashed in recovery. Otherwise it needs to be flashed in fastboot.
[Nexus 6  General] Jsunn:
Can you please help me? I'm upgrading from 5.0.1. My bootloader is unlocked and I am not encrypted. I have stock ROM and not rooted.

I just want to upgrade to to 5.1. On T-Mobile.

First I Unzip everything...

Fastboot flash bootloader bootloader-shamu...

Fastboot reboot-bootloader

Fastboot flash radio radio-shamu...

Fastboot reboot-bootloader

Fastboot flash boot boot.img (a no force encrypt boot.img)

Fastboot flash system system.img

Fastboot flash recovery recovery.img*

Do I need to "fastboot format cache"? Am I missing anything?? Flashing cache?

Fastboot reboot

Thanks!

Jason
[Nexus 6  General] :
Cache is not necessary but it won't hurt anything. Just don't flash user data.
[Nexus 6  General] Jsunn:
OK, so now with the LMY47M version, how do the above steps differ? I downloaded the 9504426dab3969b9b7da4e825ed91d4fc496cb25.signed-shamu-ota-LMY47M-from-LRX22C-fullradio.zip file but it is not the complete set of files is it?

This stuff is so confusing! :confused:

-Jason
[Nexus 6  General] Jsunn:
Can you guys please help....

I am on T-Mo and am running 5.0.1 unencrypted. My boot loader is unlocked and everything else is stock... I can't seem to get a clear answer on how to get to 5.1 (M version)?

The download file for M is not the full image and only seems to contain radios??

Can someone please help and post a full set if instructions. I can't be the only one that is confused.
[Nexus 6  General] :
The steps should remain the same when flashing factory images via fastboot regardless of software version. Just don't flash user data and you won't be wiped.
[Nexus 6  General] efrant:
There is no factory image (i.e., full image) for LMY47M yet. The file you mentioned is an incremental update to LMY47M from LRX22C. In order to flash that you need to be on LRX22C. Or, if you are a different version, wait for the factory image to be posted here.
[Nexus 6  General] x_x1_x:
OTA Update from LMY47D to LMY47E

is there any ota update from LMY47D to LMY47E? or should we flash the factory image?
[Nexus 6  General] gee2012:
The last, flash radio, system and boot.img, then erase cache and flash cache.img and reboot.

Cannot install 5.1 on stock, not-rooted Nexus 6

Hi all,

I am on my second Nexus 6 in 1 1/2 weeks. the first i purchased from Motorola, returned it and the second received from Google. Having the same problems on the 2nd phone that i had on the 1st.

Upon first booting the phone, the phone easily updated to 5.0.1. however, when prompted to install 5.1, the download either stops halfway through or after downloading completely, stops install while counting down. When it stops, the screen briefly says "device storage" and then the page says device is up to date but the phone is still on 5.0.1.. I have done the following troubleshooting steps several times.

This is a phone bought from Google and using a Verizon sim. i currently have over 50GB available so storage is not an issue.

- factory reset

- opened in safe mode to try and install

- cleared cache partition in recovery

- factory reset, did not enter any personal information or install any apps (other than what is on phone)

- downloaded over wifi as well as over verizon data only

I have been in touch with several google customer service reps who have no idea why this is happening, especially on two phones.

any help would be appreciated before i return and try a 3rd before giving up and going back to G3

Thank you very much for your help in advance!

Why not unlock the bootloader, flash the Google-provided factory image and go from there?
[Nexus 6  General] Parvinder25:
Is the 5.1 ota for nexus 6 global version out? I know the images are out but i want to go via ota route and haven't got any update yet. I'm on stock 5.0.1 and not rooted. Last time I had to force the update since it used to fail during download and this was for most. So we forced it by clearing google framework and other stuff. Just thought might have to do that again this time too?
[Nexus 6  General] efrant:
Yes, you can find it in the first post of this thread.

Why? Using the factory image or the OTA update ends with identical results.
[Nexus 6  General] Parvinder25:
Well right now I don't have a system to set-up the adb thing to help with side loading. So I thought if ota is there then it'll be good.
[Nexus 6  General] ooofest:
That's weird - my phone came with 5.0 and prompted me for the 5.0.1 OTA, no clearing needed.

I am kind of curious about timing, as I was guessing Google would make the update available via their infrastructure to Nexus devices at least in parallel with USA providers, who would manage their respective rollouts. Instead, my Motorola-purchased phone (not formally recognized by Verizon) still shows no update available if I do a manual check, but am reading reports that the providers are already making 5.1 OTA available.

- ooofest
[Nexus 6  General] brmets22:
I actually tried that with the last phone and it wouldn't work. Before i try again, i just want to understand why, if possible, this is happening to two devices. could it be because i'm using a verizon sim on a nexus 6 bought from Google? it doesn't make sense. there should be no need to sideload if OTA is appearing on my phone for download
[Nexus 6  General] :
Try this:

Pull out your Sim card and reboot. Let the phone sit for a while and see if the update reappears.
[Nexus 6  General] brmets22:
That worked! thank you. such a simple solution that i overlooked as well as 5 customer service reps at Google. very much appreciate your help and anyone else who looked at this post.

have a great day!
[Nexus 6  General] :
Great news! Glad it worked as I remembered a similar issue back when 5.0.1 was released and people had problems with Google or Motorola purchased phones on Verizon.
[Nexus 6  General] Parvinder25:
I tried the same thing but it didn't work for me. Mine is also from Google but from the first batch that got released after launch in November 2014. I haven't cleared any google framework app/data or anything else. Do i need to?
[Nexus 6  General] :
That's not recommended. If you do, you'll most likely have to do a factory reset afterwards to get Google apps to sync.
[Nexus 6  General] Parvinder25:
So sideloading is the only option?
[Nexus 6  General] :
Sideloading or waiting. But sideloading is super easy.
[Nexus 6  General] typop:
Will waiting actually work? I too have an early Google Play Nexus 6 with a Verizon sim, but since it is a pre-official Verizon Nexus, Verizon considers it a "non-VZW" phone.

I guess my ignorant question is, if I wait (which I am perfectly willing to do), will a 5.1 update eventually appear when my phone does its periodic checks for updates? I admit I don't even understand who would provide this update in my circumstance ...

Any tutelage would be much appreciated. Ignorance isn't bliss!
[Nexus 6  General] :
Google pushes updates to ALL nexus devices. Yes, eventually you will get yours if you wait. But why wait when you can sideload?
[Nexus 6  General] Jsunn:
Ok, I am on LRX22C 5.0.1 unlocked bootloader and decrypted. How do I flash to 5.1 using the "M" file?

Thanks,

Jason
[Nexus 6  General] cam30era:
This is an OTA. If you want to sideload it, you will have to be 100% stock. That means you will have to encrypt, and have stock recovery as well. Then follow the directions in the OP for how to sideload the OTA via ADB.
[Nexus 6  General] bbbasher:
I am sure many have seen this link, anyone tried the process?

http://www.androidguys.com/2015/03/25/heres-how-to-get-android-5-1-on-your-att-nexus-6/

Has the ATT OTA been captured for side loading so we do not have to factory reset the phone.
[Nexus 6  General] :
I've been telling people to try pulling their Sim card for quite a while now actually. Which OTA are you referring to?
[Nexus 6  General] cam30era:
Reread his post. He said "AT&T OTA"... ;)
[Nexus 6  General] :
Oops, missed that obviously. Anyway, [MENTION=3154366]bbbasher[/MENTION] sideload the LRX22C to LMY47I OTA on AT&T as long as you're still on LRX22C (5.0.1).

Link to OTA download here:

http://xdaforums.com/showthread.php?t=2906493
[Nexus 6  General] cam30era:
The URL that he linked to his post was the only reference that I've seen anywhere about Google starting to push updates to AT&T. I've not heard "boo" on this forum about anyone from AT&T receiving OTA. Have you heard anything?
[Nexus 6  General] :
I read so many posts in a day, it's hard to keep track. But now that you mention it, it might have been 1 or 2 posts I've read with AT&T users saying they got an OTA.
[Nexus 6  General] bbbasher:
I am considering it. I am wondering if there is any impact if it turns out the AT&T version should differ. Might be a moot point but that is why I asked if anyone captured the AT&T version. Doesn't seem to be too much hassle to follow the steps in that article.
[Nexus 6  General] :
As far as I know, there hasn't been an "AT&T version" released. You should be totally fine with LMY47I.
[Nexus 6  General] cam30era:
[MENTION=3154366]bbbasher[/MENTION],

I am on AT&T. LMY47D worked fine for me. I'm now on "I" and it's fine too.
[Nexus 6  General] ooofest:
I am still 100% stock. After reading the sideload instructions, I then saw the topic on unlocking after various upgrade steps and wondered if that had anything to do with going the sideload route, because it seems that some folks are hitting bootloops with locked phones in certain scenarios - guess I don't know which scenarios those might be.

I am willing to wait for the OTA (which was not sped up by removing my SIM), but if the sideload method gets me safely to a stock upgrade faster, it sounds like something to consider.

http://www.androidguys.com/2015/03/25/heres-how-to-get-android-5-1-on-your-att-nexus-6/

The above article references a possibility of no updates until June I assume for AT&T. Hopefully this can't be true. I thought Google sent out the updates, but apparently the phone companies are, which I find strange for a nexus device.

I have a Motorola direct bought device running on Cricket Wireless which is an AT&T MVNO. I wonder exactly how the release is going. IS it by region, by purchase date, by serial number, it actually reads the Sim and sends depending on what network one is using it??? (and if this is so, what about MVNO's), or exactly what is the release pattern.

My 2012 Nexus 7 has already updated.

I purchased NExus device specifically so as to get latest release WITHOUT having to flash - I want to stay stock and I don't wish to fool around with flashing or even side-loading. But waiting until JUNE?
[Nexus 6  General] :
AFAIK, Google pushes the updates. If there is something Sim related that could be blocking the update, that has not been confirmed. Feel free to try this though:

Pull your Sim card out and reboot. Let the phone sit for a while without Sim and see if you get the update.
[Nexus 6  General] atcchris:
I think everyone with AT&T sim cards are pretty convinced that AT&T controls the release of any update to any phone with an AT&T sim card.

They come from Google directly, but not until ATT gives the go ahead. I agree there is no official confirmation of that from anywhere, but all of the evidence seems to point there.

Different builds for each carrier, no ATT Nexus owners reporting the update received with sim in, however they get the update when they remove it for a while... It all seems too much to be coincidental.
[Nexus 6  General] :
Post #2 updated with link to recovery flashable OTA zips. Thanks [MENTION=1567974]Q9Nap[/MENTION] for creating that thread.
[Nexus 6  General] lightfire:
Thanks. Tried that but nothing. Guess I either wait or side-load - think I will wait a bit.

My Nexus 7 2013 has not yet gotten the update either.
[Nexus 6  General] ooofest:
Nexus 6 bought from Motorola and on Verizon Wireless. Pure stock 5.0.1 after initial setup, no root/unlocking/etc.

I did try removing the SIM and waiting some hours for 5.1, but the OTA was not made available via WiFi - either automatically or via manual update checks.

After reading how connection with the carriers might somehow be involved, I took the advice in this Phonearena article and it worked to trigger an OTA:

Ensured my backups were made (although, I missed a couple of recent app-specific items, oh well)

Removed the Verizon SIM and did a Factory Reset under the Backup settings in Android

Restored my apps under my Google account but kept the SIM out - only connected via WiFi

The prompt for an OTA "System Update" to 5.1 happened quite quickly, so I let it download (410.4MB) while all the apps were automatically restoring in Play. After over an hour of restoring apps, I let the now-downloaded OTA install and the phone rebooted into 5.1 build "D."

I then powered down, re-installed the Verizon SIM and booted back up. Verizon service connected again.

Question

: what triggered the System Update notification after a Factory Reset + no SIM that simply removing the SIM didn't trigger? Should I have waited longer after removing the SIM under 5.0.1? Now that my OTA experiment is over, can I sideload to a later 5.1 version at this point?

- ooofest
[Nexus 6  General] eng_saad:
Thanks,

But I can not put the phone in Fastboot mode
[Nexus 6  General] cam30era:
Have you tried "ADB reboot recovery"?

---------- Post added at 06:38 AM ---------- Previous post was at 06:32 AM ----------

You made a backup, so I assume you had TWRP installed? To install an OTA, you have to be 100% stock (no root, stock recovery, stock kernel, encrypted...)

If you reverted to 100% stock and installed the OTA, then you can not install a different OTA for 5.1.

What you can do is fastboot flash the factory images for any of the different versions of 5.1.
[Nexus 6  General] ooofest:
This phone has never been rooted, customized, etc. - I began as full stock before the factory reset and OTA.

All of my backups were at the app level, via standard Google backup/restore and some manual backups of data for specific apps - I did lose some custom data, all my UI configuration, etc. This was an experiment, so I was willing to deal with the minor hassle of manually restoring some things, essentially.

So, it sounds like fastboot is my route to take for installing later 5.1 releases, thanks - does that mean I need to deal with the OEM unlocking procedures seen in other topics, perhaps?

. . .

(for all)

I'm still wondering why my stock 5.0.1 system prevented the 5.1 System Update from being recognized, even with the SIM removed, that a factory reset apparently "cleared" (for lack of a better term) such that the OTA could go through. What flag or status does the System Update utility check before looking for available OTAs?

I got a Nexus 6 with the thinking that OTAs would come straight from Google without carrier involvement getting in the way. That seems to not be the case.

- ooofest
[Nexus 6  General] cam30era:
[MENTION=4221023]ooofest[/MENTION],

Yes, you will have to unlock your bootloader to fastboot flash factory images. Or you can download the OTA and sideload it without unlocking.
[Nexus 6  General] ooofest:
Oh, even better - sideloading seems the less problematic route.

- ooofest
[Nexus 6  General] cam30era:
Choose which one you want wisely. You can only follow this route from 5.0.1 to 5.1 via sideloading the OTA, once.
[Nexus 6  General] ooofest:
I think your responses above have me admittedly confused : per my prior posts, I am on 5.1 D via OTA.

Now, I want to move up to E and it appears that Google's OTA isn't supporting anything beyond D for awhile.

First, you indicated I should use the fastboot method with the stock 5.1 ROMs, then that sideload could work, but now this latest comment seems to imply sideload only pertains to moving from 5.0.1 to 5.1.

The whole unlocked bootloader issue is worrisome, as I've seen posts from others with bootloops and locked phones when they thought that they were following the correct steps, but I've also seen posts which seem to detail the steps needed to have success and could try it, if needed.

- ooofest
[Nexus 6  General] cam30era:
Sorry, I forgot that you were already on D. My bad. Your only choice is to unlock BL, and flash the E image.

Edit: all you need to flash is the system.img and radio.
[Nexus 6  General] ooofest:
Cool, thanks for your help.

- ooofest
[Nexus 6  General] cam30era:
Welcome. I assume you're aware of the risks, and method of relocking your bootloader on 5.1?
[Nexus 6  General] ooofest:
I've been going through the topic on unlocking that rootSU started , the beginner's stickied ones and various ones people have posted on their problems with fastboot upgrades - so, hopefully I'm getting it down. I usually take my time with these kinds of things, because it's been awhile since I was customize-crazy with my relatively indestructible Droid Incredible :).

- ooofest
[Nexus 6  General] cam30era:
[MENTION=5302753]Evolution_Freak[/MENTION] has created a new thread on how to safely relock.
[Nexus 6  General] hondajohn88:
I apologize for not seeing that in your original post. Try this:

Plug your phone into your computer.

On your computer, open a command prompt window and navigate to your android SDK platform-tools folder (wherever you put it when you downloaded & set it up)

In the command prompt window, type adb reboot fastboot

EDIT: type adb reboot-bootloader

That should put your phone into fastboot mode, and you can follow my previous steps.

It is very strange that you can't put your phone into fastboot mode using the power and volume buttons... I've not experienced that before.

I hope you're able to get things going on your nexus. Please let me know if these new procedures help, and also please let me (or anyone here) know specific procedures you've tried. Thanks :)
