Hi, Leraeniesh...

Yes. But it sort of depends on what you mean by 'root for the leaked images' ... and which, by the way, is now official:)...

https://developers.google.com/android/nexus/images#nakasi

***

Here are the 'raw materials' you'll need to root Lollipop on the Nexus 7 (2012)...

This is a

very

rough 'n' ready guide, and requires a working knowledge of fastboot.

No doubt, at some point, a better guide will appear soon, that will more formerly codify this procedure ... and inevitably there will be updates to the various toolkits...

-------------

***

TWRP available here... openrecovery-twrp-2.8.1.0-grouper.img

http://techerrata.com/browse/twrp2/grouper

Fastboot flash this...

***

Modified kernel (boot img) available here...

http://www.mediafire.com/?y7nofqvjgwccpjv

This can (theoretically, but I haven't tried) be flashed via TWRP... I just extracted the 'boot.img' file from it, and fastboot flashed it. But by whatever means it's flashed, this modified kernel is an ABSOLUTE NEEDED prerequisite for root under Lollipop.

***

Chainfire's Root package available here...(BETA-SuperSU-v2.19.zip)

http://xdaforums.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133

Flash it via TWRP.

***

--------

...and if you use Titanium, you'll find the version on PlayStore now no longer works, and doesn't recognize root, and so....

Titanium Backup test build available here... (TitaniumBackup_6.2.0-test4_r341_Market.apk)

https://twitter.com/TitaniumBackup/status/486824099663319040

Download and sideload...

Titanium should now recognize root, and work normally. It seems to work for me:).

-----

Hope this helps.

just use wugs root
[Nexus 7 General] AndroidGee209:
seems like neither work for me I keep getting no SU binary installed
[Nexus 7 General] GedBlake:
Yes... well... you can do that as well... but you're not really learning anything!

Where is the adventure, if everything is done for you?

And what if something goes wrong.

Wugs and similar, are all fine and dandy, WHEN THEY WORK... but if my experience of tech is anything to go by, sooner or later, something ALWAYS GOES wrong eventually, and the linear driven algorithms employed by toolkits are simply not up to the task of dealing with unexpected conditions... and then you've got to get grips with command lines arguments in order to fix what went wrong:(.

And it helps if you've got a bit of prior understanding in the basics of Fastboot and ADB....

-----

But leaving aside all that...

Where is the joy, if it's all done for you...

...when I became aware of the recent leaked build of Lollipop, I downloaded it... and, whilst doing so, what was going through my mind was how to flash it... how root might work!?... would it need a different kernel!?.... and a myriad other different thoughts!!

I was excited, and I relished the forthcoming intellectual challenge...

...not 'how can I make this easy with a toolkit' ...but... 'why is this interesting; why doesn't root work this way, but another way, it does?'...

Endless curiosity...

This, I think, exemplifies the XDA way of thinking, and why there are so many great developers here.

Endless curiosity... Chainfire didn't become the respected developer he is today by relying on toolkits.

For me, personally, the phrase "just use wugs root", is the very antithesis of everthing XDA stands for... sure, 95% of the time, it'll get the job done... but it's like giving a kid a calculator. He eventually 'knows' the answer to everything, whilst actually understanding nothing:(.

-----

I suspect this post will probably go unheeded... in these days of fancy GUIs, command lines seem a little old hat... but you know, a knowledge of the basics could very well rescue one of your devices one of these days:).

Let's hope so:).

Cheers, all...

Rgrds,

Can I root without installing a custom recovery? (using the nexus root toolkit)
[Nexus 7 General] salutcemoi:
Yes
[Nexus 7 General] GedBlake:
Hi, wade_county...

If the Nexus Root Toolkit is capable, then yes it should be possible... all toolkits, as I understand them, are just fancy GUI 'wrappers' that run command lines.

So, specific to your request here, that command line would be...

fastboot boot custom_recovery.img

...and which 'remotely' boots a copy of TWRP from your PC... whilst your Nexus 7 is booted into it's bootloader.

***

I used it yesterday myself in order to create a 'virgin' (unmodified, with stock recovery and stock boot) Nandroid backup of Lollipop prior to my rooting it.

***

And which now involves doing two things...

1) Flash, via TWRP, a modified kernel (boot.img)...

http://www.mediafire.com/?y7nofqvjgwccpjv

2) Flash, via TWRP, Chainfire's v2.19 SuperSU root package/zip....

http://xdaforums.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133

Hope this helps.

Nexus 7 (2013) rooted Android 5 installation

Hi there,

I have rooted Nexus 7 (2013) 4LTE...

Does anybody know if root will work with Android 5? Should I upgrade?
[Nexus 7 General] spidey88:
Hi, tried to flash the TWRP but when I boot into recovery it shows android robot with red exclamation mark instead of TWRP. Any idea what's wrong? Thanks in advance :D
[Nexus 7 General] optimus 1:
Can we flash the ROM through cwm or twrp recovery?
[Nexus 7 General] cryptoncore:
To flash a stock factory image you'd need to flash using fastboot. For a simple installation just google wugs nexus toolkit and select the result that says nexus root toolkit. Worked for me perfectly. Even downloads the firmware for you.
[Nexus 7 General] anderuc:
I just received notification for 5.0 update moments ago, check yours.:)
[Nexus 7 General] danny8:
I second this advice.

There is value to learning the tools and commands you cited, but for most people it's more reliable to use NRT. Assuming you have a PC for running NRT.

Also I'd go for a fastboot install over an in-place update, if possible. Seems that problems are less likely to occur, and you'll be better-equipped to deal with problems if they do. I bet it's faster too.

I believe this major update to Android is not easily flashed using alternate recovery programs such as CWM or TWRP.

You must restore the factory recovery program if you want to do an OTA update. This step alone is more trouble than it merits (for most mortals) if you previously installed CWM or TWRP.

Allow Nexus Root Toolkit to take your hassle away. Do a fastboot install of the appropriate image for your device.

After you see the new OS works for you, use NRT again to root your device, if you desire – and (optionally) install TWRP or your favorite recovery program. Voila!
[Nexus 7 General] deny_kei:
Just update ota to android L with root and old twrp and it work like a charm. Root still attached but my Bluetooth cannot connect to by speaker .. ?
[Nexus 7 General] danny8:
I too have bluetooth problems.

Bluetooth turns on/off, but other devices are not shown, nor can my Nexus be seen by others.

To be fair, I also had non-working BT in my previous ROM. I wonder if my bluetooth hardware is broken.
[Nexus 7 General] deny_kei:
I have read it somewhere there is bugs with bluetooth, but in my previous kitkat rom bluetooth was fine for tranfer and audio.

Just wait patienly for dev to create new rom for android L :):)
[Nexus 7 General] KainamHD:

[Nexus 7 General] ThePhoneGeek:
Forgive the dumb question but I normally play in different sandboxes and just happen to be working on the kids N7.

In order to take the OTA the bootloader needs to be locked correct?

I had previously used Wugs tool to root but just wanted to confirm the right process for taking the OTA.

Did someone a benchmark on lollipop? I feel that lollipop wont run so smooth as kitkat on my n7 2012 32gb wifi.
[Nexus 7 General] jb.traveller:
I am still waiting for 3g image. Any news yet?
[Nexus 7 General] Tmzdroid:
Yes the bootloader needs to be locked for OTA updates. Wugs NRT will do it all for you though (the 5.0 update) if you want to stay rooted.

---------- Post added at 03:52 PM ---------- Previous post was at 03:44 PM ----------

I did a Benchmark with Quadrant and scored 5286 (5.0 lollipop) On 4.4.4 it was 3794 ( both totally stock ). Lollipop runs well on on my Nexus 7.
[Nexus 7 General] ThePhoneGeek:
Thanks, I did relock yesterday but the OTA isn't available yet it seems for auto download so I just wanted to confirm that was all I needed to do.

Thx

MG
[Nexus 7 General] GedBlake:
Hi, Tmzdroid..

This is incorrect... OTAs pay no attention to the lock status of the bootloader.

There is no discernible benefit in re-locking the bootloader... and indeed, should you wish to run fastboot commands again, (or by proxy, via whatever toolkit you favour) the bootloader will have to be unlocked again, and with the consequential wipe and factory reset:(.

Hi, moregadget...

If it is your intention to manually flash the OTA yourself, then yes, you will need an unlocked bootloader... but only because you'll need to fastboot flash a Custom Recovery first, such as TWRP... and is a prerequisite for flashing anything. And in order to run fastboot commands, the bootloader MUST be unlocked.

***

However, if you're going to take the OTA normally, as and when it become available for your device... It doesn't really matter if the bootloader is locked or unlocked

OTAs, delivered over the air, are bootloader status agnostic. They simply don't care:).

***

What can cause an OTA to fail, is if the user had made significant changes to either /system or /boot partitions.

For example, flashing something like the Xposed Framework... or a custom kernel, like Franco's... 'cos that replaces the factory stock boot.img.

***

An OTA is not a full factory image... it consists of a collection of patch files, that patch the pre-existing files in the system partition.

You may have noticed, (but probably not recognized), this behaviour on Google PlayStore, when updating some app. The full reported size of the app isn't always downloaded... just the patch to update the app.

Well, something similar occurs with OTAs... system files are patched, in order to update them.

However, before this can occur, the OTA must first run a checksum verification test on all of the pre-existing files in /system... in order to ensure that they haven't been modified.

So, if just one file fails this checksum verification test, the whole OTA is aborted with no changes made... And with something like this error message...

Verifying current system...
"/system/vendor/lib/hw/power.grouper.so" has unexpected contents.
...
...
(status 7)
Installation aborted

It's only after the verification phase has successfully passed, that the OTA moves on to the second phase.... Actually patching the files in /system and upgrading each file accordingly.

***

So, in conclusion, and to answer your question...

...the bootloader locked/unlocked status is immaterial to OTAs...

What matters, is what changes,(if any), you've made after you've unlocked the bootloader.

Hope this helps.

Rgrds,

Ged.
[Nexus 7 General] Tmzdroid:
I never knew that GedBlake I always thought everything had to be returned to stock to get ota updates ( including bootloader ) its something to remember for the future thanks. I do apologise moregadget if my misinformation has caused you any problems.

Come one Google...
[Nexus 7 General] NCguy:
I still don't have 5.0. I'm assuming you have to get 5.0 before you will see 5.1? BTW, in the latest android central poll over 40% are yet to receive 5.0. This rollout doesn't feel normal at this point.
[Nexus 7 General] rbeavers:
They need to fix it. Your lucky you don't have it yet, IMHO. I sometimes wait seconds for it to respond. No you won't need

5 to goto 5.1.
[Nexus 7 General] NCguy:
So far the OTA is from 4.4.4 to 5.1 and not 5.0 to 5.1?
[Nexus 7 General] rbeavers:
It was your question? And if you look around you can put 5 on if you want.
[Nexus 7 General] slemon:
Still nothing for my 2012 wifi. It's pretty slow now so I am curious if 5.0 will improve things. Good thing I mostly use Nexus 5:)
[Nexus 7 General] ConstantineTheGreat:
You will be disappointed with performance on 5.0. But, good thing for me, when I started to look for a solution, I found out f2fs roms like rastapop (5.0) or slimkat (4.4.4),and now, my nexus 7 (2012) is flying.
[Nexus 7 General] namhuy:
got 5.0.1 few hours ago. everything went smoothly. dont know how s battery life yet but i ll update

Nam Huy Linux http://www.namhuy.net
[Nexus 7 General] razielpr:
I don't know but this 5.0 doesn't look like the 5.0 on any other device the animations are not the same they look just like 4.4.4 only thing I have seen that changed is the boot animation and the system colors and icons other than that it's like 4.4.4
[Nexus 7 General] woshiweili:
Glad to hear I'm not the only one who still hasn't received the 5.0 OTA... I wonder what's going on. My Nexus 9 has been receiving OTA updates pretty quickly. :eek:
[Nexus 7 General] erica_renee:
WHAT?>>>

what is this.. JUST A POST TO GET PEOPLE TO CLICK THREW YOUR SITE.
[Nexus 7 General] NCguy:
Just got 5.0.1 for my 2013 wifi. Never got 5.0. So far everything is good. Hang in their people, we are fortunate to get a later build this time.
[Nexus 7 General] Gr8Jeepin:
That would be nice just to skip 5.0 and go right to 5.0.1. This just send like a very long time for a nexus device to get an OTA. the Kit Kat updates were much more timely. Anyway I may just run the took kit on it and call it good. One question with the took kit, that wipes all data correct?
[Nexus 7 General] NCguy:
Depends on the toolkit and what you're trying to do. If you unlock your bootloader you will wipe your data. If you flash a stock rom you will also wipe your data. Do your homework and backup before doing anything with a Kit.
[Nexus 7 General] D_wolf:
13th December still no update. Trying to survive the material design anxiety.
[Nexus 7 General] slugger09:
Still nothing here almost a month later
[Nexus 7 General] Gr8Jeepin:
The reason I'm holding off right now on just running the tool kit is I'm just unsure if I can back up my girlfriend's candy crush data. But she's been complaining of the slowness and screen issues. If I use titanium backup, that should save the game progress correct? Oh I know about backups... Saved my butt more than a few times.
[Nexus 7 General] NCguy:
You can't use titanium unless you are unlocked and rooted. Unlocking will wipe the data. You might be able to back it up with helium backup.
[Nexus 7 General] Gr8Jeepin:
OK. I'll look into it. Thanks
[Nexus 7 General] iolinux333:
Nothing here either. 32gig WiFi. In the great northwest. I think they probably pulled it. I tried factory reset, creating new Google account, no Google account. I know I could do it manually but I'm not pressed. The point of this N7 has always been just to see what the stock Nexus experience feels like. Right now it feels meh.
[Nexus 7 General] sergiotca:
Has OTA been pulled off?

So... is there anyway of knowing if this is the case?

I've been patiently awaiting for the OTA to come to my 32g Wifi device and now I'm starting to read this rumor that it may have been pulled off by Google because all of the performance issues people are reporting. Is there any real confirmation of this or is this just some people's assumption? :confused:
[Nexus 7 General] thePrashant:
Android Lollipop 5.02 is available.. Any body updated?
[Nexus 7 General] slugger09:
So 5.0.2 is out, I've not got 5.0 yet. It must be secretly pulled. No other reason for this delay.
[Nexus 7 General] iolinux333:
It's just an assumption. There was never any official word. I guess what we're all trying to say is: "Don't panic! You are not alone ."
[Nexus 7 General] erica_renee:
This is Normal.. But Google should Post it for d/load and Manual Install. This will happen before the push to devices Start. Usually.
[Nexus 7 General] tu3218:
Flashing back to stock now! Hopefully we get a file soon.
[Nexus 7 General] AndroidGee209:
Yeah I just saw that ? they need to release the factory images already ?
[Nexus 7 General] Angristan:
The factory images will be available very soon, but the OTA updates takes a lot of time to go all around the world, so It can take hours or days, or even weeks.
[Nexus 7 General] jadesse:
Just like all the articles that said the the OTA was going to come out last Wednesday. I have no doubt that it is coming but the question is when. We'll get when we get it so, stop worrying about it for crying out loud. I am surprised that we are getting it at all.
[Nexus 7 General] AndroidGee209:
if it bothers you that people are worrying then why even click on the thread and comment? ?because obviously they're still gonna do it.

It's pretty easy to flash the factory images, and even to make sure you keep your recovery by editing the flash script. I'm just going to back up, try a hopeless dirty flash by taking the userdata lines out of the script. Then, when that doesn't work :) I will flash the image without the recovery wipe, and see if Chainfire's SuperSU works for us so that I can restore with Titanium. The script is stupid simple to understand, so its nothing to be afraid of. Screw waiting for the OTA.
[Nexus 7 General] Double :
Have been waiting patiently all day for N7 2012 update, haven't gotten anything yet. I've hit the 'check for updates' button nearly 6 times today, very excited for it.

I have read lots of 'surprise' coming from the news that N7 2012 will receive 5.0 .. but to be perfectly honest, I have no idea why devices with capable hardware shouldn't receive the new update. If they could easily run Kitkat, i really don't see why Android would want to exclude these users and create a new 'gap' in the platform userbase. Being up-to-date is something everyone receive, especially in this day and age, security purposes and all. Not everybody can afford or may want a new device.

Calm yourself mate, nothing wrong with excitement.
[Nexus 7 General] cryptoncore:

[Nexus 7 General] Uninen:
So has ANYBODY actually got the update yet? Nearing "10 am" on 4.11. and im not seeing ****. Im thinking its not even out, as this whole "release OTA in batches" is just BS, GOOGLE = INTERNET, they have the servers to push it to all at once, especially on the limited number of devices they chosen to release it first to. Least they could do is to release the factory images so we could do it ourselves, but no love there either.
[Nexus 7 General] cryptoncore:
I'm response to uninen. They never confirmed that it was being released on the 3rd of November. Go onto the website and they state early November so all we can do is wait. I have to admit it sucks though.
