I had the PA android build of 4.4 running on my tablet and decided to flash the franco kernel, which put me in a bootloop. I have since then flashed stock back onto the nexus 7 but with no luck at all, it's still in a bootloop. I tried to flash Clockwork mod onto it, but it got stuck on the google logo when i tried to boot into it.
I've been screwing around flashing stock images back onto the device but nothing seems to be working.
I'm not really sure what I'm doing wrong here so any help would be appreciated!
I'm not sure if this is the same issue I had before, but after going back to stock I've always had to do a factory reset (you can do it from stock recovery), otherwise it would lock up at the X screen.
that did the trick. I've never actually needed to do that after flashing back to stock before, but it seems to have done the trick!
Of course I missed something obvious like that though 9.9
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 .
I just got my update!!!!!

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.
I tried restoring back to factory after being stuck in a boot loop, thinking my root was the issue or something idk. I used flash tool to try and flash back to stock and fac reset and it gets to the end where MiniOS tries to do its thing but i get no promts and it just says factory reset status 2. its driving me insane trying to get this thing flashed back to stock. i dunno if im missing anything or something but im foloowing the steps like to the letter and it keeps bricking. any help or advice here that could help me out? and sorry if this doesnt go here and stuff. im new to the forums and all that.
Hi,
I had the same problem yesterday. Even worse after that factory reset status 2 my phone couldn't be detected anymore by flashtool 1.8. So I tried the kdz method. This worked for me and from stock I was able to use one click root and flash twrp with flashify. Then I went straight to android 8.1 with magisk root. Don't forget to flash mr bump after root without any reboot in between.

yeah i ended up getting it out of status 2 and tried to run stock for a bit but ended up having issues where it would just randomly shut itself off. and then boot loops. switched out like 3 different batteries, (1 that came with the phone, a not so great quality 6000mAh, and a new stock lg battery) and still having boot loop issues. so im thinking that the phone is just dead. so with tax season coming up soon i may just wait and get that new sexy razer phone. i need something new anyway and better than this walmart zte placeholder im using. lol
I've had Google phones for years now, including previous Pixel, but I just got an XL 2 yesterday and I'm regretting it.
It's Google unlocked and running June's latest image. I've experienced various app crashing on stock, and random reboots.
Then there's the rooting and flashing. I unlocked the bootloader and installed the most recent, twrp (the one verified to work on xda for roms) but can't flash anything.
My twrp either hangs on the twrp start screen, or when it does load, the touch screen doesn't work. When I can get it going, every rom I flash gives me an error on the second step. I'm flashing on slot B by the way, that's what boots up when I boot to twrp.
Lastly, I am unlocked both for flashing and flashing_critical thru adb, so I'm at a loss and seriously confused.
When I FIRST unlocked everything, I was able to flash Nitrogen rom but I got stuck at the rom splash screen.
Tldr:
-What is the Correct install method/sequence for roms?
-do the slots matter?
-is random reboots and app crashing on stock a sign of a hardware issue?
I haven't installed a custom ROM on my P2XL, so I'm running rooted stock. Anyway, for rooted stock, this is what I did.
Entered bootloader mode.
Booted into recovery using the command "fastboot boot recovery.img", where "recovery.img" is the TWRP recovery iteslf. In my case, I renamed it "taimen.img".
Flashed the TWRP installer zip needed for the P2XL (Required if intending to replace the stock recovery).
Rebooted into recovery.
Flashed a custom kernel (Recommended - resolves touch issues in TWRP).
Flashed Magisk.
6. Rebooted.
If installing a custom ROM, flash it prior to the custom kernel. Slots only matter if running stock. Random reboots and app crashes are not signs of a hardware issue.

Ya know my friend, after our conversation yesterday, and your questions in the nitrogen thread, and now random reboots and app crashes, I think it's time to consider a factory reset. You shouldn't be having those problems on a stock setup. If that's not successful, then I would definitely consider an RMA. Just my 2 cents worth :good:
I agree. I got it used tho which is an issue.

Just so you know, I got the rom to flash finally, but it's stuck at the rom splash screen during first boot. I'm going to leave it and hope it eventually boots up.

If it doesn't after 5 minutes, do a hard restart with the power button. If that doesn't work, then reboot to twrp and flash the rom and twrp installer zip again.
Ok cool thanks. I relocked bootloader last night and went back to stock. Unlocked it all this morning from my work computer and different unlock app. So here's hoping.

I finally got everything to work. My vendor image is a mismatch but I could just flash junes and be done with it, right?

What did you do to get it to work? You could just flash the June vendor.img to both slots. If you keep getting a vendor mismatch, probably nothing to worry about according to the Dev of nitrogen.
Different machine, cable and unlocking tool.
But I went to bone stock with locked bootloader, then flashed the newest twrp with the newest all in one tool. Was on slot A so wiped everything and flashed rom plus twrp again. I rebooted system to slot B, but then it just hung at the rom splash screen.
So I did it all over on slot A, ignored the "no os installed" message and booted anyway. Then it fired up. Rebooting into twrp from there took me to B, which is where I need to be for an image file or root.
So yea, thanks for the help.
I'm having this issue also. I tried flashing nitrogen, it hung. I tried to go back with factory reset Img and nothing happens in adb. Flashed the may img and it wouldn't boot all the way up. Now I'm stuck in bootloader trying to figure this all out. Seems like nothing in doing is working. I can get recovery to boot, but no files inside so idk. Tried to sideloadb nitrogen, but it said adb out of date for device when sdk is fully updated.

You didn't mention the out of date message in your other post, but uninstall SDK and then download the stand-alone adb/fastboot binaries from May of this year. Dump that in a folder (eg. c:\adb) and put that folder in your path statement. Manually flash the full factory image without modifying flash-all.bat. Post your screeen if you have any errors. :good:

Google knows the date the phone was purchased based on imei number and honors their warranty by date, not owner. Unless it was blacklisted.
