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.
I dont get 5.0 on my nexus 7 2013, wifi, 32 Gb(flo, ktu84p)
I had stock rooted Rom, u Used tweaks like softkeiz etc. then I unrooted, locked boot loader and flashed stock recovery. Android lollypop rollout was about 2 months ago, but I don't get 5.0 ota. Now I'm running 4.4.4 stock rom , locked boot loader and I unrooted it with super user unroot option. Can somebody help me why I don't get my ota?? Thanks ^^
I know that's wrong thread, I didn't find thread for my question .

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.
Ok guys I am pretty sure I fubar'd my tablet.
I am stuck in a recovery loop. When I start the tablet it just goes back into recovery. Which if I still had TWRP I think I could still do something, but I flashed cyanogen recovery trying to flash cm13 since I cold not get anything else to work. I cannot boot into download/firmware update screen. The screen just flickers a little and goes dark.
A little background:
Started when tablet forced install of 5.0 update and I was in a recovery loop. I flashed 410 test build, rooted, flashed twrp, installed stock rooted ROM. Everything was fine. Then tablet did it again, this time I just flashed rooted ROM and factory reset. Even took the steps to fix the white lines and storage issues. Was working fine. Got home a few days ago and I was in a recovery loop again. But now I don't have the bootloader screen/download mode/firmware update screen (whatever you want to call it) so last night i tried to download cm13, Gapps and cyanogen recovery with no avail.
I can access adb on my PC while in recovery, but when I try to access ADB shell I get unauthorized something or other. Because I cannot authorize USB debugging, because ROM won't boot. I tried to flash stock rooted ROM from cyanogen recovery and it says not signed or something like that.
Does anyone have any ideas? I really think I have screwed the pooch here.

if you have a stock recovery image flashing it is easy, i had a LOT of troubles with my v410 and still am working with it. i have mine rooted, just with TWRP though, i cant use xposed framework, which negates why i rooted this in the first place. anyway, through much grit and determination flash your stock image after wiping what needs to be wiped and doing all other necessary things. Then, you must download kingo root, supersu, superuser. flashify would help with the flashing i hear, but it has troubles with the v410. kingo root was an apk i managed to find buried under a million viruses on the 34th page of google..or something. rooted mine in one click, from stock to reboot to twrp root.. many glitches.
I need help myself, deleted my "Phone" system app, causing me to lose connectivity with my data plan. cant seem to restore it, and flashify nor twrp has been able to flash a custom recovery, or a backup, im at a loss.
Help? We seek the same thing.
Ok but how do I flash the stock recovery image. I can't use fastboot. ADB says I am unauthorized.

Anyone have any other ideas?
I am at a complete loss. I am by no means a developer, but I do know my way around. I really think I have FUBAR'd this one.
Kind of stinks, I give up. Anyone want a bricked v410?

I have an HTC One M9 that's rooted with the CM 13 based on 6.0.1, and I have TWRP Recovery installed. I wanted to unroot my phone and install the stock ROM to my phone because I have some physical problems with the phone and some software problems that aren't related to the root or CM 13. I followed a guide that said to get ADB and Fastboot on my computer so I did that (AT this point I had already gone to TWRP and wiped the device including the OS) and then it said to get the stock ROM. I tried to look for the stock ROM and I found a few so I tried one. It said to flash it by using commands on ADB to flash it. I did all of the commands it asked and when it came to typing "fastboot flash recovery (file name here)" it said waiting for device and didn't ever change. I tried putting the zip file onto my device and then lashing it using install on TWRP and it failed then automatically restarted the phone with no OS so it was bricked. I waited for the battery to die and then booted the phone into recovery mode. This is currently where I'm at. I live in Canada and use Bell so I can't find the stock ROM on the Official HTC website, or anywhere else for that matter. I would like to use my phone so any help would be appreciated. Thanks!
Hello everyone,
yesterday I flashed a new Cyanogenmod 14 nightly (12062016) for my G4 from earlier nightly in TWRP. After reboot the phone keeps going back to TWRP and I can't seem to get it to boot to system..
I tried factory reset, reflashing back to old nightly, flashing stock.. but nothing seems to work.
Also tried doing this in the TWRP terminal:
dd[space]if=/dev/zero[space]of=/dev/block/platform/f9824900.sdhci/by-name/fota
Didn't fix the loop, I guess because it wasn't the OTA update that caused the problem in the first place.
If anyone has an idea, I would greatly appreciate the help!
Thanks.
If you can reach download mode you could try reflashing back to stock then starting again.....Hope you get yours fixed - Sorry to say this but mine did a very similar thing only 24 hours before you posted!!! Only mine was on stock FW and was in use at the time - I've now had to swap it as valuebasket who sold me the phone have ceased trading. If yours is a UK model you may be able to get it replaced under warranty - believe that LG guarantee their phones for 2 years and a ruling by the European court said that flashing a custom rom doesn't invalidate any warranties.
I have the same exact issue, I also flashed the latest CM14 nightly and cannot get the device to boot any rom.
I have even tried flashing stock rom but I get the same problem.
From what I have read, the bootloop issue happens once the device boots but I don't seem to be getting that far.
Any ideas?
Ran into the same problem 3 days ago. This is the first time I have encountered a non-revertible issue in 3 years as a cyanogenmod user. This changes my opinion on how safe it is to make use of a custom ROM. I tried to wipe everything, reinstall TWRP, change TWRP with another recovery, reinstall a safe NAND backup of mine.....nothing.....it went into boot loop. Before I read this post, I was convinced my phone encountered the infamous G4 bootloop problem.....now I see there are other examples, so it shouldn't be the case. Long story short, I had to check my device in at the LG assistance, with 25 days as time forecast.
The guilty nightly was 20161205.
I have never seen anything like this...
This has solved it for me - I installed LG Bridge and flashed the factory firmware using the tool. Now it seems I'm back on stock but at least it's working.
got mine working. I had to install LGUP and flash stock ROM. Once flashed I installed CM14 and I am back up and running again.
I tried LGUP but it could not recognize the device while this was looping.....a bad experience......
I have the same issue. My phone was updated to 20i via the original stock firmware, then I put twrp 3.0.2-0 and cyanogenmod on. I did a cyanogenmod update from within cyanogenmod, which just booted into twrp, then I manually installed the update zip that cyanogenmod had downloaded, then it always boots into twrp. I wonder if initiating the update from within cyanogenmod was the cause. The phone is not detected by LGUP or LG Bridge. I've tried this on a win10 machine, and a win7 vm from linux. I have access to twrp, and download mode by doing the reboot into bootloader from within twrp.
If those people who have fixed this could give more details about how they did it, that would be good. What exact steps did you take? What stock firmware version did you have before installing a custom rom? What OS version were you using? What twrp version?
Well. Mine got stuck in bootloop for the second time today. What is going on? In between the two bootloops I had one good update with CM. Using TWRP 3.0.2.1. Steps to reproduce failure: updating CM from within CM, it autoreboots into TWRP and after that nothing happends, no autoinstall. Then after a manual install of the new CM the bootloop starts.
Resolve the problem:
* Install LGUP 8994 DLL Ver 0 0 3 23, Install LGUP Install Ver 1 14, get the latest KDZ
* Get the phone into download mode with usb cable and after that in firmware update mode
* Startup LGUP and choose refurbish and select the kdz file.
* After that you can boot into your stock LG firmware again, reinstall TWRP an CM. If you want so.
Read that it is advised to manual update cm from within TWRP. TWRP will get an update in the future to solve this bootloop problem.

I second that. Same issue and neither LG Up nor LG Bridge will recognize my device. Looking in device manager there are no serial interfaces. Do I need a special driver that provides a com port for a phone in recovery or fastboot mode?
---Edith 2016-12-12: Found a solution for my issue:
The phone has to be in _download_ mode, not in recovery or fastboot. After realizing that I have to boot the phone in a different manner, it will be recognized by LG UP.
Here is how to boot the pone in download-mode:
- Power off your LG device.
- Press and hold Volume Up button.
- Connect your device to PC with a USB cable while holding the Volume Up button.
- You’ll boot into download mode with “Firmware Update” written on top of the screen.
Now everything is fine again.

I was able to get out of that by also wiping by-name/misc. Don't do that, though, because then your wifi mac address will get messed up and you'll spend all day looking for a permanent fix for that.
I suggest reflashing a stock KDZ using LGUP, as others have said. You can get the usb drivers from LG Bridge.
I will release a fix for that soon. Check the twrp thread for updates on this.
Hi
I also have this problem
I installed cm-14.1-20161201-NIGHTLY-h815 successfully and was running it for almost 2 weeks without issues, today I updated to cm-14.1-20161213-NIGHTLY-h815 from cmupdater and I have been ending up in recovery every time I rebooted.
I tried flashing the latest cm recovery and reflashing the rom, with full wipes but no luck.
Full steps of recovering would be appreciated (for example, there are comments about flashing the latest stock rom, but a link to this rom would be helpful)
Thanks
Good news regarding this:

The above will fix TWRP bootloop issues as well and I also released a first h811 version which should allow installing CM etc as it should.
Keep in mind that this is a BETA and not an official TWRP release.
Please report back in the above thread!
.
Does your twrp beta really fix the boot loop even it is already happening. What do I have to wipe? I have not managed to get out of the boot loop despite intalling it.
Is using using LG Up to flash to the stock rom really the only option?
Edited 2017-01-25 2:45 pm:
Well, sometimes you just have to be patient. Powered down the phone and when th H815 restarted CM did boot. Great. :good:
Hey, I just want to share a small detail, possibly a fluke that helped me overcome the bootloop.
So...I started with a fresh, stock H815, I don't quite remember the firmware version..it was something like version "20g"..
OK, I looked up several guides and tried to get the newest stable versions of each tool. I went through with the official bootloader unlock, then moved on to rooting: Kingroot didn't work for me so I went on installing twrp in fastboot mode so I could afterwards install supersu and root.
I got there eventually but first I was stuck in bootloop - kept ending up in twrp interface. I found the 2 dd commands but those didn't work for me as the msm_sdcc folder did not exist, but instead there was a "f9824900.sdhci". Tried to overwrite this one ...but as others have stated as well, it didn't work.
At that point, I had nothing to lose, I was starting to accept that I had soft-bricked my precious G4 so..I went on installing the DU 10.6 7.1.1 rom and the stock gapps, wiped dalvik, rebooted and held my breath...not literally
About 12 minutes later, after an endless red, spinning logo, my shiny ping pong paddle showed me a different screen, a fresh start welcome screen .
Almost 24h / 10-12 reboots (twrp included) / 70+ apps installed and removed later, the new OS holds around 2G ram average, a bit better battery life, smoother transitions, flawless navigation, flush streaming over both 3G/LTE & 2.4/5 G wifi.
FYI the reboots were intended, wanted to see consistency in boots - we're in the green . Now testing long term stability with moderate/high usage.
There is 1 aspect I noticed, there are a couple of contexts when the interface burps (several menus, various situations, never in apps) and resets back to homescreen...but I think that's more of a launcher topic than an OS one.
Other than that, so far I'm happy with the mod.
Hope my experience helps others that might be in the same spot I was or at lest boosts their confidence to try out a decent idea they might be pondering.
I recently dug out my old G4 to see if I can repurpose it for anything or just have it as a back up.
It's an H815 European variant with unlocked bootloader. When I last used it I had it running a custom ROM but when I got a new phone I wiped it somehow with TWRP (this is a few years ago so I can't remember).
Now whenever I turn it on, it boots into TWRP. If from TWRP I choose reboot to system, it boots to TWRP.
I tried to install a ROM but it wouldn't, giving the error "this ROM is for P1,G4,H815 (or something like that), your device is .".
So, I edited the ROM metadata and took out the device requirements and it installed fine, as did GAPPs & SuperSU, but still it only boots to TWRP. I've flashed bootloaders, kernels, god knows what else, but it only boots to TWRP. That's it.
I also tried to return it to stock using these: https://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848 but it had errors connecting to servers and never installed anything.
I'm aware that I won't be able to recover anything on the device and that's fine! I just want to boot it with ANY ROM, and I'd be grateful for any help! Thanks!

Try latest rom and one by one different rom. It's rom related issue. Don't worry, it'll be okay.
