[Q] Failure to apply 4.3 update on my nexus 7

For a few months or so I've been running my tablet on the 4.2.2 update and have had the device rooted and never really took advantage of said rooting and so decided to undo it.
Just to check I downloaded Root Checker to verify root was undone and it says that it has, including apps that needed root access no longer work, however there are some small issues that struck me as odd; 1. When going into fastboot mode it still says that it's unlocked, unless that's referring to the bootloader which is still unlocked, 2. I still have custom recovery installed unless that's an issue in which I can undo if need be, 3. Whenever attempting to apply the 4.3 update it reboots my device as it says it will, but upon getting to the google splash screen it goes right into custom recovery when it attempts to apply the update but suddenly goes to the custom recovery main menu without applying the update.
And finally when going back to my settings and it says my system is up to date.
So is there a step that I missed in unrooting my tablet? If so please let me know, I'd like to update to 4.3 as soon as possible and take advantage of it's new features.
Namely the Open GSL 3.0 has me intrigued.

You have the old nexus 7 tab. This is the forum for the new one. The new one launched on 4.3 and I think the old one is in the process of otas.
And for any device you need stock recovery to take an ota. Any further questions need to be addressed in the proper forum.

Thanks I guess? I must have misunderstood, when I clicked the forum link I didn't see anything distinguishing it from the old one to the new one.

Besides the 2013 part?

Well at the time I didn't think anything of it and assumed it was the same forum as before and didn't bother to look as I rarely did before.

[question] OTA QUESTION??

I am currently using N7 FHD (2013) with JWR66N 4.3 jellybean. I have just UNLOCKED BOOTLOADER but NOT ROOT or install any RECOVERY.
ALL ARE STOCK ROM, STOCK RECOVERY JUST BOOTLOADER UNLOCKED.
After that I got a CLEAN (Wiped) nexus. and I got a 5X MB OTA from google and I reboot. but after that, the android robot lied down and showing a RED ! icon and "ERROR".
I rebooted my device, it starts up normally.
IS THAT I CANNOT USE OTA AFTER UNLOCKED THE BOOTLOADER????
WHAT IS THE CURRENT NEWEST BUILD NUMBER FOR NEXIS 7 2013 FHD 32GB??
how can I get that OTA again???

If you really didn't modify or remove any of the stock files, then you are probably suffering from the JWR66N won't update to JSS15J problem mystery we are trying to figure out here:
http://forum.xda-developers.com/showthread.php?t=2380258
We know that it is caused by a file on your tablet being different than what is expected and we know how to workaround the problem. We just don't know why it is happening in the first place.
If you want to help solve the mystery, post on that thread.
If you just want to get JSS15J it may be quicker to just use the JSS15J factory restore here:
http://developers.google.com/android/nexus/images#razor
(factory restore will wipe your data so back up first)

Thanks for your info.
I think i can re unlock my bootloader again.
I am afraid that BL unlocked cant enjoy OTA and now i understand thats the OTA file error from google and not mine.
But google is still so stupid that they cant reconize my OLD (non full HD 2012) nexus and new 2013 nexus. They both have same names in google play store. Thats weird

I think you understood properly, but I didn't answer your question directly, so to be clear, the OTA, under normal circumstances, would work fine on a tablet with unlocked bootloader (unless files were modified or removed)
What we are trying to figure out is why for some tablets there is a rare occurrence of a file not matching the shipped set of files that everyone else has. It is usually just one file, /system/app/PrebuiltGmsCore.apk, but there was one example of someone having the same issue with /system/lib/libchromeview.so

[Q] Is lollipop as problematic as they say on nexus 7 2013?

Hey guys
It's been three weeks and I still haven't received the OTA for Android 5. I went to the nexus 7 forums on Google help Center and I saw a lot of people having problems after the OTA. I'm just asking, have any of you faced the same problems? Did you get the OTA or did you fastboot/sideboard it yourselves?

I flashed the 5.0 factory image on my Nexus 7 this past Wednesday after making a backup of my 4.4.4 system. Only issue so far was YouTube not working, but a simple reboot cured this, & the problem hasn't come back. Lollipop has been great for me so far. (Unlocked bootloader, root & TWRP)

I'm using a pure aosp build of 5.0 because my USB port is broken, so if I revert to stock to get the ota I will most likely be stuck in an unrooted, stock state.
Haven't had any issues whatsoever, so much so that I also updated my girlfriend's N7 to the same setup I am using and she loves it too

New Nexus Owner Seeking Advice

Hi folks! Just received a 2013 Nexus 7 from my fiancé as a birthday gift. I wanted it for quite specific purposes so was hoping I could ask a few questions here and get pointed in the right direction before I start using this thing
I intend to mainly use the tablet for remote play with my PS4 and emulating old console games. Since I want to connect a PS4 controller to it wirelessly I'm told I need to root the device. I'm guessing this is an easy process and there are some guides on the site here?
The main thing I was after advice about is firmware updates. The system came on 4.3 and has already downloaded an update for 4.4.2 but I haven't installed that yet. Is this firmware fine to upgrade to? Any performance issues? I've heard people saying that upgrading their Nexus to 5+ (Lollipop?) has created a load of performance issues and this should be avoided? Also, if I upgrade to a certain firmware version can I lock myself out of being able to root the device? I'm pretty sure all of the apps I was planning on using work no 4.3 so I have no reason to upgrade at all but if I can go safely to a higher firmware that is reliable with no performance issues I may as well?
First time using an Android device so sorry if my questions come off as a little stupid. Also, wasn't sure if I should post this here or if it should be on the Q&A board so sorry if I've got that wrong!

As far as I know, the problems with lollipop were the standard number of complaints that come with any new release. Well, I'm not really positive, but lollipop seems fine to me and I think most people have upgraded by now. I would go for it because I think it's really fun to use.... Plus you can always revert if you choose.
As far as rooting, you never need to worry about not being able to do it... Rooting your Nexus 7 will always be easy. The by-hand method is fun and relatively simple, or you can just use the toolkit in the forum to do it even easier.

^Yeah I'll echo that. Lollipop is good. The people having problems don't know what they're doing. Flash the factory image.
If you want root you can use cfautoroot or simply flash twrp with fastboot then flash the su.zip

Personally, I'd stick go for 4.4.4, as 5, 5.0.1 & 5.0.2 all have a memory leak issue. You may also find more emulator compatability as Kit Kat has been around a year longer than Lollipop. The only downside to KK over L is the battery life is a little worse IMO.
I dont think the memory leak issue is a result of someone not knowing what they are doing etc.

Thanks for all the advice everyone

I'm fairly competent with computers (as I should be with a degree in computer science!) but this is all like a foreign language to me. I guess I'm better sticking with the toolkit for now until I'm familiar with all the lingo?

Thanks. This is the sort of advice I was after and is why I mentioned what I was planning on using it for. The device has already downloaded 4.4.2 and wants to update to that. Is there a way I can manually go to 4.4.4? I'm worried it will just request an update from the Google server and try to jump straight to a version of 5

If you unlock the bootloader then familiarise yourself with ADB and flashing factory images, you can manually flash any version of Android (That has been availible for your device,) manually. You dont need to be rooted to do this.
It also allows you to go back when you've made the mistake of updating, (but does wipe all of your data!)

It ended up offering me the updates incrementally anyway. I went from 4.3 > 4.4.2 > 4.4.3 > 4.4.4 which I'm currently on and will leave it there for now. It's downloaded 5.0.2 but I've skipped the install for the time being
Think I need to do a little reading up before I root the device as I haven't got a clue what some of you are talking about haha. Thanks for all the advice so far though

No problems.
I've had a few Nexus devices and never felt the need to root them. :angel:

The majority of problems stem from Qualcomms crappy broken mess Adreno gpu drivers, hence the delayed
rollouts of Android for the Nexus 4 and 7 that both use the Adreno 320, don't be suprised if the Nexus 4 and 7 get a
Android 5.1.1 release instead.

For ppl new to nexus devices, wugfresh nexus root toolkit is a great tool until you get the hang of adb and fastboot. With a nexus you can always switch between android versions. You can always root, or go back to older versions of android. Updating to newer versions never hurts anything because you can always go back. Its a developers device so its very versatile. Try lollipop if you like, (I love it) and if its not your thing, just flash back to 4.4.4. I love this tablet.

You for got to mention the disclaimer if your tab came with 5.x.x out of box you cant go back to KK. Also a lot of us who recently bought Nexus 7, I have 3 that I have acquired, came with 5.0.1 installed are having issues with partitions/memory mounting in recovery. Some sort of revision done in the latest batch sent out. If his tab came with 5.0.1 or higher and has his bootloader at FLO 4.04 he may have problems trying to go back with either bootloops and what not.

OTA update LMY48T on WiFI version ?

Just received an OTA update and was quick to press Install but it was only LMY48T (from LMY48M, never rooted). Tried googling and all I see the 7 (2013) WiFi was suppose to go from LMY48M straight to MRA58K and LMY48T was only a security update for Nexus 6, 9, and 10 which was required before going to M. Should I still try to flash MRA58K manually?

I've just had the same. Odd isn't it?

Ditto

LMY48T has now appeared on the Google factory image web site. We must have received this OTA update before this was posted. OTA to 6.0 must now be soon.

Me 2

argh, ditto! I have a notification that an update is available, cool! 9MB only, the LMY48T

Even I received a quick security update for Nexus 7 2013 (LMY48T) and is listed under factory images in Google developers (developers.google.com/android/nexus/images) site now. Seems like Nexus 7 got that security update too. Also Nexus 4 got that security update(LMY48T) too.
So Nexus 4,6,7,9,10 got those updates. Hopefully will get Marshmallow update soon.

My Nexus 4 also got this update. According to the Stagefrigt detector app it fixes all known Stagefright vulnerabilities.
Your Nexus 7 2013 will get Marshmallow. Nexus 4, Nexus 7 2012 and Nexus 10 won't.

So is there a link anywhere for a, OTA link for the Nexus 7 (2013), from this new build number, {OTA update from LMY48T to MRA58K}? Where is the new link? / There seems to be one or more devices' with the LMY48T to Marshmallow, but I do not see one for the Nexus 7 (2013).

I too cannot find the appropriate Marshmallow OTA for LMY48T. I tried the update for LMY48M but that did not work.

anyone got a solution for this? cheers

This is so annoying. Is there a way to roll back the security update to sideload the available OTA, because otherwise it's getting a fingerprint mismatch.

Should be out in about a week

I messaged the Google Dev team on Twitter and they said it should be out in a week or so.

Installing the official Google marshmallow 58k factory image is no more difficult than installing a sideload 48t to 58k image.... Just install the full fresh 58k image and be done. Take control. You can't complain about not having the latest when it's there for the taking. You just have to do it.

I thought sideloading the complete image would wipe the device. That is what everyone is trying to avoid.
If that isn't the case, then bonus!!

any news on this?

No I haven't heard or seen anything yet. They said about a week or so, it might be a little longer still.
You can just tweet them yourself. @googledevs and you can also check the hashtag #ghelp as well.

I have the LMY48T trying to get to marshmallow, but surely something is jacked up with my system and adb.. I do i adb restart to recovery, and get no command, so i then i push the buttons to set to install a ota, on my pc says no device when i try to side load. weird cuz it let me reboot using adb.

Finally got OTA update and went straight from LMY48T to MRA58V and apps/games seem to launch so much faster.
