OTA not working for me, firgerprint error :(
[Nexus 7 General] phrozenstare:
well i spent the better part of the day trying to upgrade my n7 2012 tab to android L with no luck. i has the tab rooted usingf the nexus root toolkit.after trying to flash the OTA update using root it didn't work so i used the toolkit again to remove root access and lock the bootloader and i even did a factory reset after locking everything again. then i used ADB sideload to load the OTA onto my N7 tab and it looked like it was working but still it kept me on 4.4.4 after reboot now i don't even know if i can receive the OTA update from google even after i put everything back to stock.

N7 grouper tablet build KTU84P

edit: after trying another ADB sideload with the original name of the PTA file i was able to get it to install. i had a copy of it on my tab too so i deleted that as well

Certainly I have KTU84P but recovery says something else.
[Nexus 7 General] Yaz75:
It's been said on the Nexus 5 and other forums but I'll re-state it:

You can not have any other recovery, root, ANYTHING other than stock everything for the OTA to work. If it compares just one file and it doesn't match what it's looking for, then it will quit the install. No exceptions. And if you have some leftover files from a previous recovery or ROM then that'll bork it as well.
[Nexus 7 General] jjimenezjj:
So, my device is on CM11. Am I able to the just flash the LRX21P zip from recovery and be good to go with Lollipop?
[Nexus 7 General] Yaz75:
Nope not at all. You can not. Revert to stock, remove root and custom recovery. Then you might get it to work. If you want it to have the best chance of updating, then flash the 4.4.4 factory image, then apply the OTA.
[Nexus 7 General] jjimenezjj:
I thought so. Thanks for the info!!
[Nexus 7 General] milski65:
If I understand things correctly this is just started to happen with lollipop. You could be rooted rommed in prior versions and POSSIBLY get OTA to work, even if you didn't want to. But that's changed now and you need to be completely stock for it to work.

OTA

http://www.androidpolice.com/2014/11/13/flash-all-the-things-lollipop-ota-update-zip-file-roundup/

working without unlocking bootloader and without lost any data
[Nexus 7 General] pjcons:
"possibly"? Never would this work... Don't worry I've tried and tested it (like some others on here should).

If ur not sure something is going to work, take a nandroid backup 1st and test it yourself. Why ask questions here about things u could test and REPORT back to here?

Also if u do not know how to flash an image file (using fastboot) , stop reading this thread, pack up ur N7, take it back to the shop and go line up with all the other sheep and get an ipad.
[Nexus 7 General] milski65:
I should be more specific. On multiple phones rooted and rommed I've seen more than one occasion of OTA trying to install itself. I was merely making an observation to a previous poster, posted via AP, that stated lollipop will NOT allow OTAs to install without being on strict stock.

I do in fact know how to flash files using fastboot, so that point you made is moot.

Always an occasional wisea$$ here on XDA. I see you've not changed my outlook on that observation.

You can pm me if you'd like to discuss this further.

I am on android 5 aosp. Can i normaly flash the factory image of android 5 trough fastboot?
[Nexus 7 General] timo625:
For all the impatient nakasig users: I've successfully flashed the nakasi factory image on my tilapia device. Everything is working except 3G but I don't need it.

At first I've flashed the 4.4.4 factory image completely and then boot, system and userdata from the 5.0 nakasi image and it booted up!

Have fun :)
[Nexus 7 General] bftb0:
You are in the wrong thread. OTA and flashing factory images with fastboot have nothing to do with each other, excepting that the OTA and factory images tend to come out at approximately the same time. The OTA downloads are PATCH bundles which transform an extremely specific release version into a second extremely specific release version via PATCHING. The factory images are 100% complete images sufficient to install a release on a completely blank device (well, the bootloader needs to be there). Way different.

To answer your question (read: reward you for posting in the wrong thread), on the 2012 N7, you can always use fastboot to flash a complete set of factory components to restore completely to uncustomized stock. Usually this implies "starting from scratch", not updating an existing device and retaining user personalization.

What is typically less likely to succeed is applying an OTA to a customized ROM (e.g. AOSP, that will almost certainly not work). Also not likely to work? Having a custom recovery correctly deal with things like radio firmware images or bootloaders present in an OTA download.

The raison de etre of this thread is to allow folks with 100% STOCK devices to download the OTA file and perform an "update.zip" installation of the OTA - using the STOCK recovery - a little bit earlier than just waiting around for it to arrive by random carrier allocation schedules. OR - if they have hung back from adopting many updates - they can upgrade to a specific release without having to update to the most recent (current) release, using the same method (flashing an "update.zip" file on the SD Card using the STOCK recovery).

Nexus 7 2012 lollipop update

Hey guys, please help.

i am pretty noob!

i received ota update and i clicked download and install, after the install was finished i got an red triangle and error, i held power button and now my nexus won't start, it is stuck at boot animation.

please help

i had stock kit kat, unclocked.
[Nexus 7 General] AuroEdge:
This may not be your only option, but I would suggest getting Google's official factory images and flashing those over fastboot
[Nexus 7 General] setege:
Thanks, i did that and it worked.
[Nexus 7 General] robgee789:
where are the system.img and boot.img i cant find them in any of the folders, i found boot.img.p is the thr boot.img but i cant find system at all
[Nexus 7 General] RainGater:
When you extracted the original zip, there is another zip inside. Open that and you will see it.
[Nexus 7 General] optimus 1:
My tablet is 16 GB, but after flashing lollipop it is seen 6gb. Why? How can i solve this problem?
[Nexus 7 General] Primus76:
Only way I have found is to do a factory reset. It is the fix listed by Wug and others. Happened to me as well. As soon as I did the factory reset and it booted I was good at 32 (27).

For others, any way to increase the /system partition size easily? I have 0MB free after having busybox/Supersu installed. Can't use DiskUsage (says out of memory) on the root required partitions, etc.

Thanks
[Nexus 7 General] sindawe:
Hi All,

I have a question as to which firmware I should install and upgrade from.

I have two wifi only groupers that have KVT49L (one is running PacMan and the other is running Purity).

I did a search on this thread and found a couple hits on KVT49L but I think the results said it was changed to only be an OTA update to VZW users. My devices don't have cell in them, just wifi, so I'm not sure if it applies to me.

My question is what should I flash to get these devices fully up to date so that they can run Lollipop on them? Also, do I have to go from one version to another in sequential order, or can I just flash the latest? I'm rooted on both and running TWRP for recovery.

Thanks,

Sin.

Lollipop of nexus 7 mobile

I've been waiting for a nexus 7(mobile) lollipop update for weeks checking every week but I can't find it. So does anybody know if asus is making lollipop available for the mobile tablet
[Nexus 7 General] oldblue910:
They will. There is a delay on both the 2012 Nexus 7 3G and the 2013 Nexus 7 LTE. The hangup is most likely Google waiting for some kind of code from Asus. It'll get the update, just not sure when yet.
[Nexus 7 General] neontsunade:
i still havent gotten the ota :/

i havent gotten the ota from KTU84P to LRX21P ktu84p being the current build of my device im correct in understanding that lrx21p is the update my device requires but i havent gotten the ota for it yet i live in aus and dont exactly want to root my device can i trick my device into thinking its recieved the ota
[Nexus 7 General] Mirhawk:
I haven't yet received the Lollipop OTA update on My WiFi only model of Nexus 7. Anyway to make it find the OTA? I check for update every hour in the settings!
[Nexus 7 General] counterfeit187:
Download the zip in the OP you should be able to flash it in the stock recovery without needing to root or anything special.

You might need to rename the file to update.zip or something but that has probably been covered in the first page.

Yeah name it update.zip and put it in the main folder of sdcard.
[Nexus 7 General] mk69:
I had the notice on my 2012 Nexus 7 to download and update to 5.0 I hesitated for a few day waiting to see if it would have any problems/bugs reported by other users (I like to sit on the fence). But now the notice is gone and when I go to check for updates I am "Up to date" with 4.4.4 In the past I had downloaded the OTA file from the 1st post here, used either CWM or TWRP and loaded the update onto my N7 (2012/Wifi). Followed by doing the same with "superuser" and was up to date... Can I do the same with the 5.0 OTA update posted here??? I have read a few posts that it breaks root and/or I have to flash back to "Stock" and do an OTA from scratch... I would like to just load it with CWM/TWRP to save my current data if possible.... BTW I am currently on 4.4.4 unlocked bootloader and rooted.... Nothing added or modified....

Thanks in advance for your reply!!!!!!

:)
[Nexus 7 General] jgalvan:
I am wondering the same exact thing. I have a Nexus 7 2013 model with 4.4.4 installed and rooted/ unlocked bootloader but nothing else done to it. I want to save all my stuff and don't want to have to flash this update. Is it possible to use a custom recovery to install it and be able to save everything from complete and utter destruction?
[Nexus 7 General] weirdsciencex:
I just downloaded the update from the Google developers site. (https://developers.google.com/android/nexus/images)

I ran the flash all script which updated it to Lollipop. I then booted to the bootloader.

Downloaded the latest TWRP and used:

Fastboot flash recovery openrecoveryxxxxxxx.img

Then rebooted into recovery

Downloaded SuperSu zip from Chainfire, flashed that and booted. Took about 15 minutes.

I've had no problems at all running 5.0.

Of course you can wait for someone to do a flashable zip but it's really not a problem if you use something like Titanium to backup your data.
[Nexus 7 General] jgalvan:
Thank you for your response. I have had issues with titanium backup in the past where not all the data is restored so I have a game but no save data. Then I would spend hours trying to find the data and move it to its proper location. I will look into your method though.
[Nexus 7 General] neontsunade:
am i looking for a folder called Main or just in the folder sdcard
[Nexus 7 General] counterfeit187:
Just /sdcard
[Nexus 7 General] woshiweili:
I renamed the file to update.zip, placed it in /sdcard and when I boot into stock recovery, I see a android with red triangle with an exclamation mark and it says "No command." :(
[Nexus 7 General] MauroRTR:
when you are in the android with red triangle with an exclamation mark hold the power button and press volume up
[Nexus 7 General] woshiweili:
Thanks.

I did that and the only options I had were:

reboot system now

apply update from ADB

wipe data/factory reset

wipe cache partition

I thought it would automatically install the zip.
[Nexus 7 General] counterfeit187:
Apply update!
[Nexus 7 General] woshiweili:
I tried that and was hoping it would just automatically update but it didn't. I have messed with ADB before but it just seems too troublesome :( Guess I'll just have to patiently wait for the OTA. Thanks.
[Nexus 7 General] whpsnp:
Just make sure USB debugging is ticked in Developer settings on your device.

Connect it to your computer and open ADB. Navigate to the folder with adb in it writing code "CD name_of_folder" without the quotation marks.

Unlock the screen on your tablet and check if it is recognized in ADB. Write code "adb devices" and if you get the serial returned you're good to go.

Make sure you have the OTA downloaded and placed in the same folder as adb.

Write code "adb reboot recovery" and when you see Andy with the red exclamation mark hold power and press volume up. Choose Apply update from ADB.

Write code "adb sideload name_of_file" and wait for the transfer and update to complete. All done.

If you have a Mac you need to write ./ in front of all ADB commands, for example

./adb devices

EDIT: Huh, apparently arrows and the text between them don't show up in the post. Edited accordingly.

So possibly replace bootloader-grouper-4.23.img after unpacking.

It worries me that the flash-all.sh will do

fastboot erase boot

erasing 'boot'...

OKAY [ 1.192s]

...

fastboot flash bootloader bootloader-grouper-4.23.img

sending 'bootloader' (2100 KB)...

OKAY [ 2.191s]

writing 'bootloader'...

FAILED (remote: (InvalidState))

Wow! So am I left without a bootloader? Well it carried on and rebooted, so did it erase the bootloader or not?
[Nexus 7 General] RusherDude:
As far as I know, unless you do a fastboot erase bootloader first, it would just stay with the old bootloader and stop the flashing, you could still enter fastboot, but not recovery since there is no boot, right?
[Nexus 7 General] samjam:
Thanks for that explanation. I thought boot loader was fastboot!
[Nexus 7 General] AuroEdge:
I could be wrong, but I thought this can happen when you are running the same or newer version boot loader as the one included in the Google Factory image i.e. the script doesn't risk flashing the boot loader image if it isn't an update to what you have.
[Nexus 7 General] GreenTuxer:
I know too many people with 5.0, "broken" Nexus 7 2012 and locked bootloader, so I really need OTA zip file for 5.0.2 in order to update their tablets. I hope this comes fast.
[Nexus 7 General] RusherDude:
Bootloader is the first "software" partition that loads the phone (after the hardware boot sequence), which loads the boot (kernel). Yeah there are 1000 thing to be added to that explanation but well :P.

From the bootloader you can enter the fastboot and recovery modes. Recovery however has its own partition so if its broken it won't work (also needs a working boot/kernel or not anymore?).

Unless the script does a "fastboot erase bootloader", you would stay with the old bootloader and so be able to enter fastboot mode. Even doing the erase of the bootloader, I am not sure if it would really delete the bootloader if you don't flash another crypto valid one before. Bootloaders stuff is confusing, and for good measure...

If im wrong correct me please.

Nothing. It will just tell you that your ADB is too old and what version you need to get. The sideload does not proceed and nothing bad happens.

And, yes, the minimal ADB/Fastboot thing contains the latest version, last I checked.
[Nexus 7 General] Lttlwing16:
If you are on Linux (the only versions of the 1.0.32 I could find were for windows) , updating the SDK manager still doesn't give you adb v. 1.0.32 need to sideload the 5.0.2 OTA .zip. For my linux people out there, do the following:

1. Navigate to your sdk/platform-tools folder and delete the adb file

2. download and extract the tar.gz package linked here into platform-tools:

https://skia.googlesource.com/skia/...df394/platform_tools/android/bin/linux.tar.gz

3. copy the adb file found in the skia folder into platform-tools

4. download or move the OTA zip into the platform-tools folder (same as the adb file you just moved)

5. run ./adb sideload a6645eee89af34f58db74f6a1ad93fe400fcfc7b.signed-nakasi-LRX22G-from-LRX21P.a6645eee.zip

[Nexus 7 General] Winesnob:
Use fastboot to format the recovery partition and then flash the stock recovery again. Something from TWRP was probably retained causing the OTA update file to flag recovery as modified.

fastboot erase recovery

fastboot flash recovery recovery.img

is this correct?
[Nexus 7 General] Winesnob:
You can use "erase" or "format" to clean out the recovery partition. If erase doesn't solve the issue, try format. The latter may do a little more thorough cleaning.
