Hey.. No relax.. Your software is messed up.. Do this--->>>
1. download the nexus factory image from Google developers
2. download wugfresh toolkit
3. Go to "flash stock+unroot" and tick device is softbricked
4. navigate to the factory image you have downloaded
5. let the toolkit finish,
PS:- DO NOT INTERRUPT THE FLASHING PROCESS
The device should boot up

I tried it first; it didn't work (Nexus Root Toolkit by WugFresh) gave same message :crying:. I tried flashing standalone using fastboot commands that also gives same error. Copied the full log from NRT

the toolkit to perform other operations.
NOTE: If this process was too quick and your device

My nexus7 is stuck in a 'groundhog day' scenario, no matter what I do after reboot it reverts to it's former state, factory reset has no effect and I cant unlock to reflash, any advice? thanks

Everything I've read on this suggests a bad emmc chip or something along that lines.
I do suggest you try different drivers, perhaps from this thread...
http://forum.xda-developers.com/showthread.php?t=1907796
But if it won't unlock , you're dead in the water as far as Modifying goes.
I would return it and get another personally. ?

Nexus 4 OTA soft-brick help

I was updating my Mom's Nexus 4 to 4.4 (with the intention of bringing it to the current version to address various security issues -- like stagefright), but it appears to have "soft-bricked" as some people are calling it.
- locked bootloader
- not rooted.
- stock firmware
It goes into a "bootloop"? Where the Google logo displays forever (at least 30 minutes) w/o doing anything.
Normally I'd have spent more time doing this (e.g. backing it up, etc). But due to various personal mishaps in the past year, my tech environment is incomplete and a mess. I've never had problems w/ OTA updates so I foolishly went ahead w/o an adb backup -- which would have at least given me most files (even if I have to redo the entire setup). Also, due to poor timing, I was in a rush to get this done so she'd have a week or so before her trip to get used to the small changes (yes, she freaks out over small changes like the camera UI being different). So, whenever you're doing 2 things at once, you never pay attention to one thing fully. And this is also what happened to the OTA update -- so if there were ANY error messages or anything during the update, I did not notice. =(
Unfortunately I also don't have the device in front of me (things like work get in the way of personal masochism -- aka playing with tech).
Anyhow... I'm not exactly certain if it was going to 4.4. When I downloaded the OTA images for the Nexus 4 for 4.4 and tried to flash using the flash-all tool, it complained that the bootloader was not the right one. When I pulled down 4.3 and tried to flash, it did not complain about that bootloader version. So perhaps it didn't properly flash the bootloader? In any case, is there any chance of getting at the files now before a wipe?
What confuses me, is why I cannot flash w/ a STOCK image. Aren't they signed? Even with a locked bootloader, couldn't it in theory let the right images in?
Also, I'm normally in a windows environment, but due to my machines all being down, I'm on the work MacBook Pro instead. So unfortunately I can't try WugFresh's rootkit -- although I'm not sure it would help w/ a locked boot loader.
So... the questions are:
1) Is there a way to flash to a stock OTA image w/o losing data?
2) Or if that's not possible, is it possible to get the data from the phone?
3) Or I'm out of luck and I shouldn't waste any more time trying to recover what's lost?
(Btw, I didn't lose everything -- e.g. I have photos, sms and call logs backed up. WhatsApp used to be backed up, but it seems like both the 3rd party solution and WhatsApp themselves have stopped supporting some sort of offline backup. So mainly just concerned about files in Downloads or Documents or something -- everything else I've made sure was "on the cloud".)

First you might try going into Recovery (assuming you can) and wipe the cache partition, then reboot and see if that fixes it. I have had this glitch occur during an OTA update before (It might have been the 4.4 update actually), and wiping the cache and rebooting fixed it every time.
I am trying to understand what happened and what you did exactly. You have a locked bootloader, aren't rooted, and on stock. You are saying OTA and that you tried to flash via flash-all. Are you using the term OTA and referring to the image files in the tarball as the same thing? OTA is the zip file which only contains the files necessary to go from one version to the next higher version. The .tgz factory image file has all of the image files for a complete build. You would not have been able to flash them with a locked bootloader however. Is that what happened here? You tried to flash the img files on a locked bootloader?
Are you able to boot into Fastboot? (Power off your Nexus 4, and reboot it into fastboot mode by holding the volume down button and power.) If so, will your computer recognize your device? You should install Minimal ADB and Fastboot: http://lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378 on your Mac and see if it will recognize your device.
If you can get it recognized in Fastboot, you can then just use the fastboot oem unlock command in a terminal window. If you can get the bootloader unlocked, you can then flash the image files properly to recover the device. Here are some instructions: http://www.androidcentral.com/how-unlock-nexus-4-bootloader (***This will wipe your device and you will lose your data if you have to go this route***)

The first thing I did was to try wiping the cache after recovery mode, but that did not take it out of the boot loop. AFAIK, in 4.3 you can't wipe the dalvik cache from stock recovery. Something similar also happened to me on my Nexus 4 a while back and yes, wiping the cache then did the trick (also think it was 4.4). It fixed it then on my Nexus 4, but not on the current one.
The initial flash was applied OTA. (e.g. There's been an "upgrade" icon in the notifications bar for like over a year.) So you touch the notification, it tells you to reboot and install and I let it w/o paying much attention to it afterwards until I noticed that it only displayed a Google logo afterwards (for over 30 minutes). If that flash takes longer than that, I could have screwed up and interrupted it. :crying: I can't recall how long the 4.4 takes to flash.
Since it was in a boot loop, I thought I could reflash from the tgz images from here: https://developers.google.com/android/nexus/images?hl=en, but of course w/ a locked boot loader, nothing will flash.
Looking at this thread, there seems to be a "manual" way to unlock the boot loader w/o wiping the device IF the Nexus 4 was on a version younger than 4.3.
http://forum.xda-developers.com/nex...ot-unlock-bootloader-wipe-data-t2300480/page4 - comment 35 for "steps", somewhere else for confirmation that it's not working for 4.3 and later.
So, it seems like there is no way to reflash this phone w/ anything w/o wiping the data (4.3 and after) -- which was what this question was about.
So maybe this bears repeating (to be clear). The question is:
Is there a way to recover from a boot loop caused by an OTA update from 4.3 to 4.4 when it is a stock and unrooted rom, with a stock (locked) boot loader without losing data?
-or- Is there a way to recover the data in such a state?
Of course there seems to be a way to JTAG it, but... that scares me (since I've never done that kind of stuff): http://forensicswiki.org/wiki/JTAG_LG_E960_(Nexus_4)
But I do have another question, if I accidentally interrupted the flash, is it possible to get it going again?
This might be insightful (but probably not).

A solution!
Okay, just to update anyone following this thread.
I sideloaded this: http: // www . androidpolice . com /2013/11/21/the-nexus-4-finally-gets-4-4-heres-how-you-can-flash-the-kitkat-krt16s-ota-manually-root-or-unlock-not-required/
And it worked. But I haven't slept in over 24 hours, so... I think I'm going to sleep now (have to be up in another 4...). Will post more details later (or answer any questions).

More details
Okay, not much to add, but sometimes these details can be helpful in the future for other people.
When I first posted this, I was past the point of diminishing returns (e.g. where anything you do creates more problems than fixes them). So I was thinking down the wrong path.
ariesgodofwar pointed out that I was trying to apply a the Factory Image over the phone which was NOT the OTA image (which contains only the things it needs to do an update). This clued me in. The OTA update is always a patch. And I'm glad the factory images did not apply because inside the .tgz is a userdata.img which would have wiped all my data anyhow. So... lucky that did not happen.
Instead, I found a signed OTA update (at Android Police) and then used the adb "sideload" technique to apply it. Fortunately, it looked like either nothing was patched successfully the first time, or it happily skipped fully patched files (e.g. maybe it was a mix between 4.3 and 4.4 which was why it was stuck in a boot-loop) and never told me about it on the logs.
Anyhow, it seems to have patched okay, and then went back to the Recovery Menu where I did another Cache Partition Wipe just in case before rebooting. After that, it went to optimizing apps and everything worked as expected. :victory:
In the link above, there's another link that shows you exactly how to get it into the Recover Menu but here it is anyhow: http: // www . androidpolice . com /2012/11/13/android-4-2-build-jop40c-rolling-out-to-the-nexus-7-now-manual-download-link-available/
(btw, how on earth did I post links in the 2nd post???)

Nexus 10: Stuck in Reboot, Tried Flashing Stock ROM With Error

Infinite reboot problem
I need help, my nexus has been continously rebooting by itself. It starts, goes to my homescreen for a few seconds and reboots. I can boot in the bootloader and have tried to do a factory reset, but it just stays a long time in formatting data. After waiting a complete day I decided to stop the process and start again my tablet. It just went to my home screen and again it kept rebooting. It didn't wipe anything.
Next I tried to fastboot flash a stock image, it never gave me any kind of error. My tablet rebooted, but it just went to my home screen, and clearly the image wasn't installed. And again it started the rebooting process.

Also, I tried to re-lock the bootloader with fastboot oem lock, it said Ok, but the status didn't change (I have a 3 year warranty that will expire this december, and I think is time to use it, but I need to lock the bootloader). Thanks in advance for your help.

Hello, did you try to boot on a custom recovery ?
fastboot boot recovery x.img will work.
From there you might try formatting / installing a custom rom.

Yeah, I tried to do a factory reset with twrp, but it didn't work. It stays a long time in formatting cache using make_ext4fs function and doesn't make any progress. I left it like that for 6 hours after I decided to finish the process. It started again, went to my homescreen and kept rebooting.

You could try formatting with f2fs but fi you already tried unlock/lock I don't think it will helpas it erase the whole storage.

Thanks a lot for your help, I'm going to send it under warranty and see if they can fix it. I hope they don't reject it because the bootloader is unlocked.

PIT files
My nexus 10 has the boot loop problem and I think I have been left with the only option of Re-Partition but I need the PIT file. Can anybody help or provide this file?
I have tried everything else (fastboot, adb, temporary custom recoveries, Nexus Root Toolkit) with no success.

unlocking Bootloader without erasing userdata?

Hello,
i have a Nexus 7 2013 edition.
I updated the device and something went really wrong.
I want to unlock the Bootloader to flash it, but it don't work, because everytime i try to unlock it, the tablet wants to erase userdata. This is were the Nexus stucks.
When i try to unlock the device, this happens:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
(bootloader) Unlocking bootloader...
(bootloader) erasing userdata...
I tried to erase the partition without and with "-u" and "-w" but everything failed (i aborted because it went forever)

Can someone tell me how i can unlock the bootloader without erasing the userdata partition?
Or can i use another tool instead of adb+fastboot?
Can someone help me?

Code:
fastboot oem unlock
This will always erase userdata, there is nothing you can do about it.
You don't need to manually erase the userdata again afterwards.

Ok, but the userdata cannot be erased because everytime i try to unlock the bootloader the system crashes while erasing userdata.
Is there anything i can do to repair the device, because i'm out of options.

Google for Nexus 2013 stock images and download them from Google . As they are signed images you can flash them with fastboot. After flashing boot into android, then power down. Now you should be able to unlock the boot loader using fastboot oem unlock.
It seems the userdata partition is messed up, and the above procedure should be easiest to fix that.
