I looked into updating my 2013 Nexus 7 to Android L yesterday and hit a couple snags. I was using a guide over on nexus7root, mainly for the files and command lines.
I used Nexus Root Toolkit to get the proper drivers installed and to unlock the bootloader. Then I got on with installed L. Command Prompt got stuck at 'Erasing user data' for about an hour. Not a lot I could do but turn it off and try again. It doesn't want to get past that point. I give up for the evening and just try to turn the tablet back on. It gets stuck with 'Google' written on the screen and an unlocked padlock at the bottom. Won't go any further. I go back to NRT and select 'Flash stock and unroot' with 'Soft bricked/bootloop' selected. It whizzes through a little too quickly and my Nexus is still displaying the recovery screen. NRT says it might not have worked and to select 'Force flash mode' and try again. I do that but still no luck.
The tablet will now only display 2 screens: Google with unlocked padlock, or recovery.
Any ideas on what to try next?
Thanks in advance

You have 2 choices.
1) Start from square 1 and try to install L again using the instructions you have or other instructions that can be found right here on XDA (i wouldnt because you arent installing the actual OTA but rather the developer version which has bugs and such and you will end up having to do number 2 when L comes out anyways.)
2) unbrick your device by reflashing it to stock. there are plenty of ways to do this, look for unbricking on the forums here and you should be ok.
Just a tip for the next time you decide to flash anything if you ever do, make a backup of your entire stock system before doing so, you can do this in the recovery that you install before flashing the new rom. It makes unbricking quite a bit easier.

1) I can't update using the instructions as it hangs at 'Erasing user data'.
2) I've tried to unbrick and flash back to stock using NRT but it just goes back to FlashBoot and never finishes.
Dunno if I'm allowed to, but...
BUMP!!

You're absolutely right! Always, always make a backup/nandroid before flashing a different rom. But if you don't and like to live dangerously you should at least have the sdk installed and know how to use adb/fastboot! One thing though about restoring a backup, it does not restore the bootloader. Android L uses bootloader version 4.04 and KitKat uses 4.02. The first L preview used the same bootloader as KK but the new preview does not. I have no idea what kind of bugs or worse would result from restoring a KK nandroid onto the 4.04 bootloader. Maybe nothing but I purposely didn't try to find out if it would cause any problems. Couple nights ago I checked out the preview for maybe an hour then went back to 4.4.4. I flashed the 4.4.4 factory image using a modified flash_all batch file then restored on top of that. I guess I could have instead fastboot flashed the bootloader then went straight into recovery to install my backup. Just something to think about, bootloader versions.

You said previously "The tablet will now only display 2 screens: Google with unlocked padlock, or recovery." Unlocked padlock means your bootloader is unlocked and your device now can have images flashed to it. Recovery or bootloader screen? You need to be able to get into the bootloader screen. Press and hold the volume down button, while still holding down the volume button press the power button for a few seconds release the power button and it should go into the bootloader screen. There are a couple toolkits that might help, Wug"s and One-Click Restore come to mind. I've never used them so I wouldn't be any help as far as they go. I can try to help if you want to use the sdk. Do you have the android sdk installed?
i had the same problem , i tried one click restore and it works fine
Wow don'T!!!!

Don't delete your user data before backing it up!
See WugFreshs Threads on XDA!
So I used ATGAdmin's guide here: http://forum.xda-developers.com/showthread.php?t=2381582
Used "Dead_Nexus7.bat" and it fixed me right up. Plus, I love the "Look you dumb motherf**kers" attitude he has in his video.
I appear to be all sorted anyway! Thanks to those who suggested 'One Click Restore', it set me on the right path.

I am running the stock rom without root and unlock and I got the 4.0.2 OTA update 3 days ago. Today when I do the pattern unlock my phone froze and reboot. Now I cannot get pass the Google logo boot screen.
I am able to get into the recovery mode but I don't want to do a factory restore as I don't have anything backup yet.
Is there any solution to this boot loop problem? I am surprise that I am getting this problem as I am running the stock rom without any root / mod.
If there is no solution to this, is there any way I can backup my phone before doing the factory restore?
Many thanks!
You can back up via adb. Try searching in the General threads, since there's a long topic on this...
Good luck!
Thanks, I do find information about backup, but I can't find anything regarding the bootloop...
When i got stuck at the Google screen with a bootloop i booted into the bootloader/fastboot screen with vol up+down power and i redid the one click all process and it basically rewiped my device and put it back to working again with unlocked bootloader rooted etc....
All you have to remember is what build number you have and let the toolkit work its magic.

Sorry, forgot to mention. You're probably gonna have to wipe via recovery - which is why I pointed you to a back up...

I can't find a way to backup without going into Android. I can only go to Fastboot Mode.
Anyone know how to backup the file using abd without getting into android?
Why did make 2 threads about this. Unlock the boot loader and use adb to flash your stock. Image files. You will loose all data unfortunately but I think that's the only way to fix it.

Ok I'm stuck with the same problem now. I wanted to flash a ROM, so I downloaded AOKP, flashed it and rebooted and the phone refuses to boot past the Google logo and keeps rebooting again and again. I am able to get into the recovery. I have flashed the ROM several times and its still the same. I have done a complete wipe as well. Still no go.
Fastboot command doesnt work in the bootloader either. I have made sure the drivers are installed, still there is nothing when I type fastboot devices. If I type any fastboot command it just says <waiting for device> or something like that.
Any other suggestions? :-s
Okay it's been a few months since this has happened so I'll try to remember as best as I can; I had rooted my Nexus using WugFresh's kit, everything went fine. It was rooted for about 6 months and eventually got stuck in a boot loop (no clue how this happened, I hadn't installed any kernals, roms, even apps in months). I tried like 4 or 5 different methods to fix the issue; I finally was able to get the phone working again using ODIN mode, it completely restored it to stock (as far as I'm aware).
So I tried to re-root the phone; no luck, using ANY method I've been able to find. The main problem is I can't seem to get into TWRP, every time I try to it simply gives me the dead android with the red exclamation point. I'm not an advanced user by any means, but I'm not totally clueless and I can follow directions. If anyone has any advice for me on this I'd GREATLY appreciate it, I have an excellent 4G signal where I live and the only other internet option is AT&T basic DSL so I'd really like to be able to use my wifi hotspot again. Thanks in advance for your time, I appreciate anyone who takes the time to try to help.
1) android on its back is stock recovery.
2) follow this: http://forum.xda-developers.com/showthread.php?t=1529058
it works 100% of the time if you read and take your time.
it sounds like you have root but cant flash a recovery, let me know if im wrong but if this is the case I would just download goo manager from the market and go into settings and flash a custom recovery and that should fix your recovery problem but sometimes you have to download the recovery twice ive noticed that in the past, let me know if this works for you or you could go through the longer process above but your fix may be very simple
Thanks for the info, I will try this either tonight or tomorrow and get back to you; I certainly hope it works!

This is driving me insane. I'm trying this method; I followed the directions step by step, but my phone is showing that it is unlocked already (when I entered the fastboot oem unlock command in CP it returned FAILED: Invalid Command, but it is showing as unlocked in bootloader.
Now for the weird part; I rebooted to bootloader and tried fastboot flash recovery recovery-clockwork-6.0.2.3-toroplus.img and it returned immediately FAILED: Invalid Argument. I decided to start the process over, and now I can't reboot from CP, it's saying error: device not found.
I really want to just smash this f*%&ing thing into several hundred thousand pieces right about now, so I'm going to take a break for the moment. Are there different types of bootloaders, or is it possible the my bootloader is just corrupted or something?
There are different bootloaders, but the fastboot commands should work just the same. You're on Windows i'm assuming? You could also look at efrant's guide, http://forum.xda-developers.com/showthread.php?t=1626895, as well as his 101 in the general section stickies. It does not make sense that the device would become not found, and I would try reflashing the bootloader. Don't smash the phone!
Have you tried this method?

your drivers are not installed correctly.
My unrooted, stock Nexus 7 was on 4.4. I received an OTA notification about 5.0.1 so accepted the upgrade. After the reboot and seeing the Android with the open stomach, it fails with Error against the Android. All I can do is long power off/volume up to power off and then power on again. It then reverts back to 4.4.
After about an hour I received another 5.0.1 update, went the same process and received the same error.
Does anybody know what that could be? I guess I could factory reset the device there is nothing on the tablet that hasn't been saved in my Google account anyway.
Thanks
Wanted to say I experienced the same thing earlier today, except I didn't get an immediate second chance at the OTA. I have the wifi-only version of the N7 2013, and it is also not rooted.
Browsed around the net and various places to see if others had this issue, but no luck. Not really sure what the problem is unless the download got messed up somehow?
Same issue here. Download the update. It shows verified. Reboots, starts to flash and then the android error
Reboot and it is still 5.0
Happy to report that when I got another crack at the ota the update went fine. Still confused as to what could've caused the problem though.
Well it killed my N7 it seems. Got the error message then shut itself down. Now it won't boot up no matter what I do. Any ideas?
My update just stays in the notification area. After the failure I just power the tablet off with long press of the power button and volume up.
I am stock, rooted and unlocked. I used the WUGS toolkit to flash the stock recovery assuming that this is all that was necessary for the OTA to be recognized and accepted. After flashing back to stock recovery, I rebooted the device and told the OTA to update. It starts going through the process and dies with "Error!" and reboots back into 5.0. I tried using the WUGS toolkit to ADB sideload, but I have not been able to get it to work. At some point, it actually got into the Stock Recovery, but ADB wasn't able to contact the device (that only happened once). Every other time, it goes through the script and shows the Android on it's back with the exclamation mark, and below it says "no command."
The device works, but it's frustrating. I wish there was just a way to fastboot the OTA, or just do it via TWRP.
I'm anxious to hear how others work through this, as it appears that I'm not the only one.

Tried sideloading the factory image?
Sent from my Nexus 5 using XDA Free mobile app
Since my N7 is a secondary device (my main device is a N5 which received the Lollipop upgrade fine), I might just leave it on KitKat rather than muck around with sideloading Lollipop. KitKat works fine for me at the moment. But it's really annoying that a stock N7 cannot get an OTA upgrade and goes into an Android error state.
I was on 5.0 rooted with TWRP and got the same error trying to take the OTA. So I downloaded the rooted rom found here http://forum.xda-developers.com/nex.../rom-factory-stock-rooted-rom-lrx22c-t2960745 , used Wugfresh's NRT 1.9.9 to update the bootloader, and then dirty flashed the 5.0.1 rom with TWRP. Painless and fast with no loss of data or anything.
Same problem! I managed to workaround the issue by using fastboot replacing system.img boot.img recovery.img with stock ones!

Are you suggesting that I blow away what's installed and just update by doing a fresh install? would prefer to not do that.
I did download razor-lrx21p-factory-ba55c6ab.tgz (the 5.0 factory image) and extract the recovery.img for it, and fastboot flashed it, and the no matter what I end up in the Recovery bootloop with the android on it's back and exlamation point and "No command."

If I am not wrong, there is a way of flashing the factory image without wipe by modifying one of the scripts, never did it though myself.

Turns out I was using the wrong key sequence for Recovery to get past that screen. Holding down Vol Up + Power for 3 seconds, then just pressing Power gets you to the right place. Am still having issues with OTA, as the system believes something was altered (install-recovery.sh). Others are saying that the way to do this is as described here: http://forum.xda-developers.com/showpost.php?p=57271130&postcount=423

jep, that's what I was saying earlier: factory image. For the 5.0.1 update you only need system.img and boot.img, at least that way it worked for me and my N7 2013 is running fine so far.

Oh man! It's crasy, I was waiting so long, and exactly on this day when I write to thread I get my update!
EDIT: Never mind. I tried to do it via sideload, and it complained that the /System was too full. I rebooted, compared it to another Nexus 7, and the size was the same and free space was the same (and the other one updated fine). for the heck of it, I tried sideloading again, this time I formatted the cache first (no reason, just a thought) and that time it sideloaded correctly. So I'm up to date now... Weird.
I have the same issue. did a factory image install to 5.0. Now I get the update notification for 5.0.1 (as expected).
When I try to install it, it reboots, then I get "error" - have tried 3 times now. A reboot gets me back in the tablet, but am still at 5.0. This is my kid's tablet, so I have no need to root it or install a new rom, just want the dumb update to work correctly...

That is indeed strange...If you are pure stock it should work I guess? You could still try to sideload the 5.0.1 as well (did the same as I did not want to wait for OTA). You can do it without full wipe, just wipe cache in the process. (You need only to flash system and boot.img, wipe cache, reboot). Nevertheless let me know if you get the "error" solved, would be interested to know.

I was skeptical but this worked when I was having a similar problem to the OP Thanks. I have no idea how 5.0.1 is different though.
Hello all, I have searched for more than a couple hours and just seem to be getting nowhere. Here's the deal: I have an HTC One M8 with TWRP, root, an unlocked bootloader and S-ON. I want to install Lollipop, but can't take the OTA.
I know a little bit about what I'm doing, I tried to flash a rooted stock ROM but it didn't take. I wiped all directories but the internal storage. Also wiped the Dalvik, `but I could not get the update to take. I tried a few other things but out of fear of bricking my phone I wasn't very adventurous. I flashed the backup I made beforehand and it worked fine.
I think I have the wrong file...? Could my S-ON be the problem?
Sprint HTC One M8 (HK edition)
Android: v4.4.4
Sense: v6.0
Kernel: 3.4.0
Baseband: v1.08.20.0916
Build:3.31.654.2
All I want to do is flash lollipop. Will I have to lock the bootloader and go back to stock recovery to do it? Can I use adb sideload to install it via adb?
Thank you for your time.

I'm pretty sure my phone is toast.
PLEASE HELP, it worked just fine before I took your advice...
I relocked the bootloader and verified it multiple times before doing this. I made sure everything was exactly the way it was explained in the instructions, all files were correct.
I put the phone into fastboot, which I verified with adb.
I ran the Sprint_HTC_One_M8_HK_4.20.654.10_RUU .exe file and followed the instructions.
Both the program and pphone are currently frozen. They have been this way for almost 2 hours now.
The phone is stuck at the black HTC splash screen and the installer says
Updating...(0/7)... #(<--- these dots are still in motion like its installing)

Ok, the phone is not recognized by adb but is still recognized by fastboot, can I reboot it into TWRP by using
Code:
fastboot reboot recovery
then just flash the backup I made before all this crap started?
*EDIT* RESOLVED
Never mind, I resolved it myself. I just typed
Code:
fastboot reboot
and hit enter. It booted right up.

Right now I'm back on a fresh 5.1.1 install.
Is there something I'm missing? From all my googling it seems like I should be allowed to installed kitkat no issues on this device. What am I missing?

Right now I'm back on a fresh 5.1.1 install.
Is there something I'm missing? From all my googling it seems like I should be allowed to installed kitkat no issues on this device. What am I missing?

Do you get that android after when you try to boot normally? If you turn it off and turn it back on again normally does it still show up? It is weird if it does because that sounds like the stock recovery, and shouldn't really show up unless you try to boot into it via the bootloader.
When you follow the guide, do you also do the last step, where you interrupt the reboot to lock the bootloader? If you do could you try to let it boot uninterrupted after the update?

Hello, Thank you for replying..
I ran the flash-all.bat from the 4.4.4 image files stock from google and it got this error:
checking version-bootloader...
FAILED
Device version-bootloader is 'FLO-04.05'.
Update requires 'FLO-04.02'.
I guess my bootloader is too recent? Google does not want us downgrading?
Update: I ran fastboot oem unlock and was able to run the flash-all.bat
Now i'm waiting on the device to boot up, its currently stuck on a black screen that has white text in the middle saying "google".
Update: It is permastuck on the google screen... I don't know what to do Also to answer your question, yeah I reboot it multiple times. It doesn't work. If I choose "start" from the bootloader it will be stuck on the black google page permanently.
Is there some way I can just wipe the device and install 4.4.4 on it? Kinda like a regular PC?
You need to flash the bootloader before executing the flash-all file. To do that boot into the bootloader then use the command
"fastboot flash bootloader 'bootloader file'"
where bootloader file is the file with bootloader in its name you got from your zip file. Then
"fastboot reboot-bootloader".
Then you can use the flash-all file.
