[Q] Updated Nexus 4 with Android 4.4 Factory image. Only seeing boot animation

Hello,
My name is Rahul. This is the first time I am posting.
I flashed the latest factory image for Android Kitkat onto the Nexus 4. the image was occam KRT16O. I followed the instructions and used fastboot on mac and ran the flash-all.sh script that was provided.
The log of the script was as indicated below and the device rebooted. However, it was stuck in the boot animation for a long time.
What can I do next? The options I can consider are:
1. force reboot the nexus 4 by holding the power button [if that would work] and flashing the image again.
2. go to the bootloader (if reboot works) and switch away to the previous ROM (I was using CM and PAC for some time now flashing them nightly) and wait for a new more days.
I would love to try the new factory image for KitKat on my phone and would appreciate if you could provide some direction.
Thanks in advance for your help.
- Rahul

Rebooted and trying again...fingers crossed.

i would download again, look down in the log and u see that it just erased usersdata partition(it needs to erase and flash userdata.img)

I have the exact same problem, please let me know what what the solution for you.

I opened the zip file image-occam-krt16o.zip and found userdata.img and i used fastboot to flash userdata with that image. I am still waiting for my phone to move ahead from the boot animation...crossed fingers.

I guess that you, like me, took the wipe flag off the fastboot bat file right?
Well I was told that 4.3 --> 4.4 needs a full wipe so I put that -w back in place and everything works, my 4.4 works
and my phone looks fresher than fresh.
Good luck

opssemnik, I downloaded the file again, unzipped and tried again. It gave me the same log. I then opened the zip which contained user data.img and flashed it and it still waits at the boot animation for a long time. I think its already been twenty minutes.
Is there anything else I can try?
Thanks for your response.

Did you fully wiped your device?

Yes. The flash-all.sh uses -w which fully wipes the device. I remember reading about -w somewhere.

I had the same problem, came from PA 3.99 and flashed the kitkat google image and phone got stuck in bootloop. Only way i could fix it was to get the new sdk studio and use the fastboot from that

the last log u gave looks like mine so i guess its ok, but u were using a really outdated adb huh? im using the minimal adb + fastboot from like 6 to 7 months ago(so the fastboot / adb is from that time witch means is old) and i can flash the stock images

can you send your "platform tools" somehow? I downloaded everything today and tried flashing 4.4. Stuck at boot screen. How long did you have to wait before it went past the boot screen?

just ask him for the link as of which he got it from probably easier.
Edit: May I ask you guys a question if you skimmed through this forum prior to making a decision to upgrade you would see so many people with the same issue and post day in and day out about flashing images. I am confused as to why those of you want to flash images instead of just flashing through a custom recovery. There is no difference? other than less headaches from what I see

Yeah I'm kind of a noob. I installed CWM recovery. I boot into recovery and I see a bunch of options. Which one will fix my phone?
When I select "wipe data/factory reset", the output is the following:

Already tried that. Didn't work. Always gets stuck at the boot animation. That's why I thought of trying a different recovery. Neither works

May have to start from scratch since this is how all others have gotten past that screen or simply why not flash a zip. So much easier than dealing with images

Curious issues with Nexus 7

Okay, so I'm having what I believe to be a strange issue and was hoping someone here might be able to help.
One day my Nexus 7 (2012/wifi/grouper) started to reboot while sitting on my desk. It then would go into a boot-loop. I turned if off for a bit and every time since it does the same thing. Loads up correctly but after any amount of time it will do the same thing.
So I tried a Factory Wipe & Erase. It went through the whole deal and I rebooted it; but the device didn't wipe or erase, everything was still on the device. >.>
So I decided to flash back to stock. (device was/is unlocked/rooted). Updated the SDK and made sure adb and fastboot both work correctly and that I had the most recent updates to anything available. USB drivers are current and working correctly. Fantastic I say to myself as I go through the fastboot process of returning to stock.
Code:
C:\android-sdk\platform-tools>fastboot devices
015d2d42201c1213 fastboot
I hit fastboot devices and it shows me my device, so I go through the normal bits. This is what I get:

Alright, we're booting back into the device and it appears to have gone fine! But then I notice I'm still seeing the Jellybean "X" boot screen and think to myself well, that's kind of strange...The Nexus 7 loads up and...nothing changed. The device still has everything on it that it had previously, nothing has been changed or deleted.
I've tried deleting (user data such as music or videos) using Windows Explorer. I've tried File Manager and ES File Explorer via the tablet. But every, single time I turn the device back on...everything is still there!
So I guess what I'm trying to figure out is...am I high? Did I die in my sleep and I'm just not aware of it yet? Has my Nexus 7 been cast for a sequel of Groundhog's Day?
What am I missing here? I've done this time and time again but I don't think I've ever seen something like on any of my previous devices (or with this N7 in question as well...)
Hopefully I'm missing something very minor here and someone will make me feel stupid for it. I don't mind feeling stupid if it means I learn something new! (Any and all help would be greatly appreciated.)

I'm not an expert on these things but I basically have a question for you. If you're willing to wipe out the whole thing, have you tried doing the factory reset via settings?
Sent from my Nexus 7 (2013)

Thanks for the suggestion. I have tried Factory wipe from inside the device and it says it completes and I reboot to everything on the device.
I've also tried wiping everything out using TWRP and it to gives me a completion message, but after start up everything is still on the device.
I've also went into TWRP under advanced options, used the built in file explorer and deferred everything from the "sd card". But once again the device reboots, loads up...And everything is there once more!
That's why I wasn't sure if I might be high or dead. I am completely dumbfounded by what's occurring here. -.-

Wow! Are you there's no cameras outside your window, shooting for the next Twilight Zone movie?
The only thing I can think of is using a Toolkit like WugFresh and see if that works, other than that, I'm at a total loss.
Sent from my Nexus 7 (2013)

Oh~ ho! I have also tried Wugfresh and ADB Sideload from within TWRP; same thing occurs.
I've also moved the zip to the device from Windows Explorer to the root directory, but when I reboot to recovery to install from TWRP the file is no longer there! >_<

I've got exactly the same problem. N7 (2012) which is constantly booting into the same state. The same apps try to update themselves from the play store, the same screen etc etc.
I've tried the basic factory reset from the menus - when it reboots nothing has changed. I've removed the other user account from the N7 that I keep locked for work use. It seems to disappear, but when I reboot its there again. I've tried booting into recovery mode, selecting "wipe data/format" (or whatever it says), it says that has gone OK, then it reboots and nothing has been changed / deleted - its still in the same state.
I've rebooted into fastboot mode and used WUGS toolkit to flash stock + unroot in the soft-brick / bootloop mode (both with the force flash option on and off), they both report it is working fine, reboots and there are absolutely no changes at all made to the device.
I turn wifi off, reboot and wifi is back on again. I enable developer options / usb debugging, reboot and they are gone again. Its as if some part of the flash storage has gone completely unwritable, but what is really odd is that whilst the device is on, it behaves as if things are changing - apps appear to update, and be installed, options get changed etc. But nothing at all "sticks" after a reboot! Plus I am lucky if the device stays booted for more than a couple of minutes, it is constantly self--rebooting.
Did you ever find a fix for this, its driving me mad!!

I've got exactly the same problem. N7 (2012) which is constantly booting into the same state. The same apps try to update themselves from the play store, the same screen etc etc.
I've tried the basic factory reset from the menus - when it reboots nothing has changed. I've removed the other user account from the N7 that I keep locked for work use. It seems to disappear, but when I reboot its there again. I've tried booting into recovery mode, selecting "wipe data/format" (or whatever it says), it says that has gone OK, then it reboots and nothing has been changed / deleted - its still in the same state.
I've rebooted into fastboot mode and used WUGS toolkit to flash stock + unroot in the soft-brick / bootloop mode (both with the force flash option on and off), they both report it is working fine, reboots and there are absolutely no changes at all made to the device.
I turn wifi off, reboot and wifi is back on again. I enable developer options / usb debugging, reboot and they are gone again. Its as if some part of the flash storage has gone completely unwritable, but what is really odd is that whilst the device is on, it behaves as if things are changing - apps appear to update, and be installed, options get changed etc. But nothing at all "sticks" after a reboot! Plus I am lucky if the device stays booted for more than a couple of minutes, it is constantly self--rebooting.
Did you ever find a fix for this, its driving me mad!!

Free Beer to anyone who can help!!!

Free Beer* for anyone who can help!
I have a serious problem with my nexus 7 (2012) which I have been researching and working on for many months now to no avail. For this reason I am offering a free beer to anyone who can help (t's&c's apply)!
Background:
The device has stock 4.2.2 rooted installed along with Multirom which has CM10, paranoid android and Ubuntu (desktop).
All this ran fine for a while. I then noticed that if I made any change to the stock rom, update an app, download an app, change the wallpaper, download a file to any part of the filesystem... that when I rebooted the tablet that change would not be there... The wallpaper would be back as it was or the file simply didn't exist! It was as if the filesystem was mounted as non - persistent.
So I tried the other rooms on the tablet and realised they would not boot. All except Ubuntu which was working fine however doesn't mount the internal storage so I couldn't test any further.
I attempted to re flash back to stock. Using flashboot I cleared the cache, system, user data etc and had no errors and then flashed the stock rom. After rebooting my old system appeared to my surprise.
I have tried since then to re flash everything. Recovery won't update (currently TWRP) and the only time I get any error message is when trying to re flash the bootloader which is currently 4.18, everything seems to go well and then "signature match" appears on the tablet screen and it hangs leaving an error in the fastboot terminal reading "Remote: ()"
If anyone can help me fix this issue then the beer is yours... The only stipulation is you have to be in Ireland to claim it but what better excuse for a holiday
Thanks in advance.
Kieran

Booting up your freshly flashed stock device...
--------------------------------------------------------------
Wait for your device to finish booting up...
- It may appear to be boot looping; just wait...
- It could take 5-10 minutes; please be patient...
When its finally booted back up, please remember
to re-enable USB debugging if you plan on using
the toolkit to perform other operations.
NOTE: If this process was too quick and your device
is still in bootloader mode, then flashing stock may
have failed or been incomplete. Simply check the
log above: if you notice it skipped steps because it
didn't meet certain requirements, like the bootloader
or baseband version, then consider enabling 'Force Flash'
mode in the toolkits options menu and trying the
'Flash Stock + Unroot' processs again. Cheers.

I used the same stock rom I am using so I ddn't have to flash the bootloader which is an issue (see above).
I can't see any errors in that terminal, everything looks fine but when the tablet reboots it has not changed a single thing!! Multirom is still there as it was and my old rom and userdata and everything down to the crappy wallpaper I put on 8 months ago is still there!!
Can anyone PLEASE HELP!!!

So what do you want to do? Get rid of the multirom and get back to stock? If so do you care about your data?

Exactly that! Don't care about data, just want a stock working image.

I'm having the exact same issue. Tablet reboots after 5 seconds after the lock screen loads so I thought I'd erase user data and re flash the rom. Except that it doesn't actually flash, or erase anything. I've tried toolkits and fastboot. And the log always says the flash has performed successfully but it always reboots to the same old rom, wallpaper, all data still intact.
It's almost like the partitions are write protected and won't allow any data changes.
If anyone can help with this issue, I'll double the free beer offer!

Can I just ask, are you using multirom aswell? Your the only other person I've heard of with the problem, we should go more notes and try and narrow this down.

No multi-rom. I've found about a half dozen other threads with people experiencing the same thing. It's rare, but it's not just me. Being completely unable to wipe data has me thinking there might be a hardware issue at play.
I'll post links to some of the other threads. Thanks for offering to help. I'm willing to try anything at this point.

Xda forum help - Can't wipe using fast boot or recovery nexus 7 2012 wifi

I have a problem with my nexus 2012 WiFi version
I put twrp recovery 2.7.0.0 and omini ROM 4.4.2. Since then I have been unable to wipe anything on the device. I wipe or format in twrp when reboot every thing is same. Even with fastboot I format internal SD or wipe everything. It says it is OK but when u boot nothing is wiped. I can install apps but when I reboot they are erased and only apps which were there earlier stay. Please help. Another guy in the forum has same problem.
Default Can't wipe or factory reset Nexus 7 (2102) using multiple methods
A month or so ago my Nexus 7 (2012) started rebooting itself after a minute or so of turning on - I think this may have been during OTA upgrade from JWR66Y to new release. I tried to fix this by clearing app data and booting into CWM recovery and deleting cache and dalvik cache but the problem persisted. So I decided to reset the Nexus 7 back to factory image and have tried every means of doing so but every time I keep getting back to my original data and the app crashes and reboot continues. I have never had any issues connecting to the device on USB and ADB so this is not a driver issue. Things I have tried:
* Hard reset on phone from recovery (plus endless deleting of cache and dalvik)
* Hard reset using Wugfresh toolkit (plus near every other tool on there)
* Hard refresh from recovery mode
* Hard refresh using ADB and deleting user data etc.
* Flash recovery from ADB (also using Wugfresh as per above)
* ADB sideload from recovery of factory images, bootloaders and other ROM's
* Lock/unlock/root/unroot - using ADB commands as well as Wugfresh and other toolkits
* Delete data, system, cache
It seems like the Nexus 7 going into read only mode? Erasing /data and everything else in recovery has no effect and also when trying to overwrite the bootloader I get "writing 'bootloader'... FAILED (remote: (InvalidState))" using Wugfresh toolkit as per below. The device is still running JWR66Y.
I'm totally stuck now as to how I get my Nexus 7 back again! I have seen other people having issues with the JWR66Y bootloader (http://forum.xda-developers.com/show....php?t=1907796) but have tried all the workarounds and can't seem to find a way to overwrite the bootloader...

Seems your firmware files are missing things, as noted in your logs.
Try getting the proper firmware from another source.

Follow the guide I linked... Exactly as it says and you should be fine.

Hey when I click the link I can't see any guide or steps to follow.

Also is the guide simple to use. I am very new to all this

The guide starts on first page with post number 1.

Hey I tried the guide. Every thing goes through fine but when tab reboots it still has old omni ROM on it. 4.4.2. I also tried to update twrp to v. 2.8 from 2.7 in fastboot but no joy. It stays on 2.7 on reboot even though fastboot flashes it and says OK done. Also I cannot relock the boot loader. I give the command in fastboot OEM lock its says OK button reboot its still unlocked. But I can boot into a new version of twrp or cwm touch temporarily using wgh tool and click boot custom recovery temporarily and it does it. But can't flash it permanently. What shall I do. Feel like smashing the tablet with a hammer. I am pissed because my son has no tablet any more. I was the one who put omni ROM on it. So I take the blame for ruining it. It was working fine but suddenly it rebooted on it'd own after few weeks and since then nothing works on it. Just the stuff that was on it. Can't install anything new. I wonder why I can't even change custom recovery from twrp permanently to a new version. Please give me your guidance.

Cant Restore / format / recovery
I had rooted the device, loaded dirty unicorns and then decided to try out Liquid. Got liquid flashed and let google restore apps and such. Came back and my girlfriend mentioned there was an update to 4.4.3 and she downloaded the "update" while I was making dinner. I came back in and she said the tablet had rebooted and now wouldn't boot. So I tried to get into TWRP which was working just fine. NO Luck.... So I tried the stock restore. it just hangs at the formatting data.
So i then tried the Nexus tool kit to reflash the stock system and unroot and I figured i would just start over. Well Im now Stuck.
I have tried everything i can.....
Included is a couple screenshots.
TIA

Im confused. My device is not able to boot and therefore I cant enable debugging and use ADB. I have installed all the drivers and all the pkgs with SDK. and The toolkit finds myt fastboot device. hjowever CMD window does not.
Im not a cmd wiz and none of the cmds seem to be recognizable.

Use the guide linked. You'll be using fastboot from bootloader mode... Shouldn't need adb.
Read the guide carefully.

I'm confused.. If you can't get into bootloader, then how are you using fastboot?
And, what exactly is your device (n7 2012..not 2013 right... And WiFi or 3g model) , and what exactly are you trying to flash? What firmware file?

N7 2012 - Wifi - The Tablet shows the current bootloader to be 4.18. What I mean is when the tab is manually put into bootloader its fine but when given a cmd prompt to reboot to booloader it goes to a black screen and no response from the PC connection or on the tab
I have tried flashing the following Stock images from
https://developers.google.com/android/nexus/images
4.2.2 (JDQ39)
4.3 (JWR66Y)
4.4.3 (KTU84L)
I extracted the files to SDK platform tools folder and like i said everything erases fine via fastboot cmd's. However when I get to the flash bootloader cmd its gives an error. (seen in pics posted above) I even tried the older version of the 4.23 img link in the guide you suggested.

anyone? Anyone offer a service to restore stock image for me. Thanks

Soft bricked really hard

Hey guys, I've done something wonky in TWRP and simply cant get a clean factory imagine installed. I feel like ive tried everything and am now coming here in an attempt to get some help.
At this point, I am stuck at the Google logo booting indefinitely. When I flash the latest TWRP recovery and go into it, im pretty locked down in what I can do. I cant get ANYTHING to mount, it vibrates but wont let me mount anything.
When I go into advanced wipe settings in an attempt to repair partitions there is NO system or Data present and will not let me repair. When I do repair system, i get "/sbin/efsck -fp process ended with ERROR: 16 unable to repair system" Googling brings me nothing on error 16.
Despite trying to flash a multitude of different factory images through both WugFresh and Fastboot commands I havent been able to stick. I cant even wipe/factory reset in stock recovery.
I've attempted "fastboot format userdata" as well as flashing the modified boot.img to bypass encryption (not sure how this works?) But to no avail.
Could anyone help me diagnose this a bit? Help would be greatly appreciated.

P. S. Reading your post, I feel like you don't have much knowledge of what you're doing and especially how the things work on your Nexus. But don't worry that is nothing to be ashamed of, all of us here have been through that stage. So once we have resolved your issue, I would advise you to read the stickies in different sections of the 6P.

Hey there, thanks for chiming in.
Despite my hastily typed out response, I have a relatively good idea of what I am doing, though I know I am no power user.
I have attempted to flash stock. I started with MTC20F once I realized I was having problems. After that failed to boot, I downloaded MTC 19X and attempted to flash that. I first started with going through Nexus Toolkit to get it up and running but that still left me at the Google logo after booting. Wondering what was up, I threw in TWRP as a means of taking a look at my partitions after the stock install which is when I realized something was fishy. Nothing is able to be mounted, repaired or resized and TWRP is telling me that both /system and /data are not present directly after reinstalling Stock. and said their size is 0mb. Essentially it seems no internal memory is being detected at all.
Also I am prompted that there is no OS installed when i go to exit recovery, despite having just flashed it.
The problem I am having seems quite simple, but makes no sense to me.

Okay, I am guessing you missed something out while flashing stock. Plus, avoid toolkits for now.
Now, try re-installing stock from the steps mentioned here: http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/page1
Or to be simple, extract the factory image, and use flash-all.bat file on your PC. Let me know the results.

So I opted to go through Heisenberg's tutorial so I knew if anything happened at each step, and also locked the bootloader again after.
After going through all the steps with the MTC20F factory image (verified), it takes me right to the stock recovery with the android on his back after showing me the google logo.
Edit: it seems to be staying in stock recovery for a short period of time before going through a boot cycle continuously.
Edit2: When I go into recovery, it wont let me "apply update from SD card" or "wipe data/factory reset" or "wipe cache" It says:
Can't open /dev/block/platform/soc.0/f9824900.sdhci/by-name/misc (no such file or directory)
E: failed to mount /cache (no such file or directory)
E:unknown volume for path [/sdcard]
followed by a series of errors about not being able to mount other parts

To be safe, keep the bootloader unlocked. As for flashing stock, try the flash-all.bat script. Just a try, and let me know.
One more thing, you flashed the correct vendor image, right?

unlocked the bootloader again. Double checked and the vendor image is directly from the factory image. Went ahead and used the flash-all.bat and came to the same result; shows Google logo for about 20 seconds then right into stock recovery.
Also check my edits above about weird behaviour.

The above errors that mentioned probably indicate that your partition table is the culprit here. The stock factory image should have done it already. Might want to check out the service centre?

Thanks for the advice. Unfortunately I'm located in Bangkok, Thailand, without an adequate service centre around that can help with Nexus devices.

Could you post out the complete log when the factory image is being flashed?

Once the flashing is done, you just copy down the complete content of the CMD window, or Terminal, if you're using Linux or Mac.

Seems like it is flashing fine. I am out of clues now. Would still recommend you to go to the nearest service centre.
