If you can start the phone in bootloader mode (press volume down and power) can use the stock google images that are downloaded from here https://developers.google.com/android/nexus/images

Same here......

Download the stock Lollipop images from here and follow efrant's guide to flash your device. Make sure to try and restart your phone twice after flashing, for some reason I always get a bootloop the first time.

i can start the phone in bootloader and already tried using original image 4.4.4 but after that phone still in bootloop (the only difference that the phone now in bootloopon 4.4.4
)

I found the solution!
Guys, go to recovery options through bootloader and then wipe cache and factory reset and reboot. Then just be patient and wait for 5 minutes..

Blooming frustrating
I have the dreaded bootloop as well.
I have tried every option I can think of.
NRT with its own download
NRT with the download from the Google Factory Image site
Using the flash-all method
Flashing the img files
Clearing the cache after flashing.
Constant bootloop.
WTF am I doing wrong?
Aaaaaaaaaaaaaaargh

i cant reach recovery option - there is an icon of dead android

Same here...

I have just recovered my N4 from bootloop
Thanks to amsaiegh for efrant's guide guide but i used ADB installer v1.3 to flash the image manually
Will try to flash lollipop soon again

Problem started when I tried to install stock 5.0 android on my wife's Nexus 4 after developer preview 5.0 using NRT!!! Also boot.sig and recovery.sig are not found in flashing process... Using original Nexus 4 flash file...

Go to Advanced Utilites in NRT -> Boot temporary CR -> Wipe/Factory reset
Worked for me

[Q] Encrypted n4 stuck on nexus X logo after flashing twrp

So this is going to be a step by step of my problem. 1 I unlocked my bootloader manually without using a tool kit. 2 I proceeded to flash custom recovery twrp 2.6.3.0. 3. From the bootloader screen I select recovery and and when twrp open it immediately asks for a password that I have no clue what it is, so I click cancel.4 I go to do a factory reset within twrp and It fails, so then I go back to the main screen of twrp and select mount and I notice that the system and data options are unchecked so I check them and then there is the option to decrypt data so I select that and again I need to input a password to continue. 5 after all this fustration I then open nexus root toolkit by wug and click the option to flash stock + unroot (current status:soft bricked/bootloop). So the toolkit does what it needs to but after all that my n4 still does not boot pass the colorful X logo. So this is my issue hope I can get some help
Try going into the stock recovery and doing a factory reset from there.

Did you try a 4.4 rom by any chance? there are 1,000's of post to use CWM to be safe, and did you back up you previous rom to restore from TWRP?
If you still have a 4.4 rom zip on you device look for help on flashing CWM http://forum.xda-developers.com/showthread.php?t=1993331
If all else fails you can also try a factory reset http://www.wugfresh.com/nrt/ there is an option to tick on soft-bricked / bootlook in Wugs toolkit.
You can't "mount" your nexus 4. You can use adb to push the appropriate zips over. Or use fastboot to flash .imgs.

Yes i did try a 4.4 rom. I noticed that soft bricked thing in wugs toolkit right before i saw this post, so yeah thats what im doing right now. I should have tried the flashing cwm thing because i do have the 4.4 rom on my device, but ill just wait until google releases it or its stable.

I'm using the Nexus 5 port atm and it is stable, i used to skim over the instructions but that extra 5 minutes of reading the flashing instructions will save you hours of searching for a way to get out of a error.
3 options:
1. Adb sideload the things you'd like to flash.
2. Adb push the files onto the device while in recovery.
3. Fastboot flash the factory images.

Use nexus root toolkit to temporarily boot into recovery and wipe everything, then flash a ROM, or download a factory image from Google and run the flash-all.bat

What exactly happens? Error message? Does it flash normally but once you reboot goes into bootloop again? Be precise, I know english doesn't seem to be your first language but we need to know more

After flashing it, did you go into the stock recovery to factory wipe data before booting it up? You have to do this or else you will get stuck at the Nexus bootup screen. Happened to me once. Apparently you have to do this on the Nexus 5 and Nexus 7 because flashing it doesn't properly wipe the partition.

Hloo m.charesa,of course I wipe data,partition after flashing many times(I watched the clip in youtube does that),But unfortunately due to the nexus logo.
It seems that the problem is not to activate the USB debugging , because after opening bootloader or installing stock rom returns the device to its origin and must be activate (usb debugging) again .. Question: Is there a way to activate it without the operation the system (because its not operation originally)??​

USB Debugging is only necessary if you are trying to use ADB when the phone is on and booted into the OS already. It's not necessary when you are in Fastboot mode (at the bootloader). Not sure why it's not working flashing the factory image. This is why I prefer not to use toolkits and do everything manually. That way, you know where things went wrong.

boot loop issue
Im having the bootloop issue. I can't get into TWRP from recovery. I tried using NRT v1.9.6 to boot to TWRP and it but it wouldn't connect (ADB), so I used Boot Temporary and did a factory reset and wiped cache. Now did a 'Back to Stock' soft bricked recovery to 5.0 but still no joy. Help please!
bootlooping nexus 4 after flashing lollipop factory image wugs nexusroottoolkit 1.9.6

Press the Power button to restart into Recovery mode. You'll see an image of an Android robot with a red exclamation mark and the words "No command."
While holding down the Power button, press the Volume Up button.

5.0 bootlooping solved nexus 4
if ur struck in bootlooping after flashing factory image 5.0 on wugs nexus 4 roottoolkit 1.9.6.

boot into fastboot using POWER and VOLUME DOWN ..connect your device ,the pc will detect the device as ADB device .
then open nexus root toolkit
just click on unlock and follow the steps, twrp will be installed .
perform factory reset and wipe cash .
re boot the device .it takes 8-10min ....
Hey Wug, I just noticed the quick boot app supplied in the rooting procedure doesn't seem to work, you tap the icon it triggers superuser but then does nothing. Anyone else notice this? It's stock lollipop.
Flashing android 5.0
This is a very great toolkit! Can you please tell me whether i can flash android lollipop using this toolkit! Is this toolkit updated so that i can flash 5.0 on my Nexus 4 just like i did for my kit kat update!
Upgrading N4 to Lollipop without losing data
Personally I skipped the Unroot part and upgraded fine. The rest was as you described.
Although it sure needs much time and some reboots to complete the process.
If anyone wants to keep his data and just upgrade to Lollipop, should flash stock img files in this order: radio, bootloader, boot and system.
I am using Win 8.1 btw.
I saw this in the Wugs tool kit thread.
I really don't want to have to do a full back up and restore of everything. I am very much a root nOOb and probably would have not
rooted without the tool kit.
Can someone please type very slowly for this nOOb and tell me how, using the Wugs kit to do the above, ie; Flash the stock img files
in the order listed above?
Much thanks in advance,
Bruce in Ocala, Fl

What i did for my kitkat update was
1. Keep a nandroid backup of the phone through recovery & backup of all the data
2. Because you unlocked the bootloader you are not gonna lose any data
3. connect your device to computer and check whether it is connected using the command 'adb devices'
4. If it shows you some device is connected a serial number you are good to go
5. use the option flash stock + unroot and follow the onscreen instructions
6. Then root your device using the root option and flash a custom recovery! It by default gives the first option to flash CWM but if you want to switch to other recoveries then you can use the apps like 'flashify' after you turn on your phone
I will probably try to flash android 5.0 today because my exams getting over so i will keep you updated with the procedure if i'm able to do it
I used the toolkit to flash 5.0, HOWEVER, when you flash the images, YOU WILL BOOTLOOP. To fix this, you need to reboot into the Bootloader (Vol Down + Power), select Recovery. then press Pwr + Vol Up, and Factory wipe your device. When you reboot, it will take a bit of time, but it will reboot. Perhaps @WugFresh could add a script to factory wipe for the N4 after a flash, as more than a few have bootlooped their devices and freaked out not realizing the simple fix?
factory wipe!!!!!

Way ahead of you there is a new feature in v1.9.8. Check the toolkits options menu. The feature is called "Post-Flash Factory Reset". Enable that to have NRT auto boot you into stock recovery post flash and instruct the user how to factory reset.

Yes. However, in stock recovery you could try just "wipe cache" instead of "factory reset". Then you won't loose data, but it might not work. Worth a shot though.

You are da man! Awesome. I just updated to 1.9.8 last night, and had not had a chance to play around with it. Is there a note, or is it on by default for the N4 so users realize this? I did not run into this issue with my Gen 1 or Gen 2 N7's upgrading, so do not think it was necessary for them, but for the N4 it seems to be.
Saw your comment about just wiping cache, and would be interested to know if that works. Might give it a try, to test as that is certainly preferable to a Factory Reset.

I did not default it, or make a note for it. I really don't like hardcoding these exceptions, especially when I don't know if google will fix it in the next version. That said, I think a note might be a good idea if this is happening all the time on N4. I will put one in (conditionally for this build) in v1.9.9.
Yes, please test that if you get a chance.

@WugFresh I tested tonight, you were right. A factory reset is not necessary, just wiping the cache partition after flashing does the trick and will take it out of bootloop.
Flashing 5.0 using Flash + Stock option
I just did flash my stock 5.0 image! A very easy to use interface by wugfresh! Simple with onscreen instructions! Read and follow them......probably wont end up messing with your device!
Backup of all your files is recommended!
A backup is necessary because in my case when i flashed the image is when it wiped the entire Internal Storage! I did not enter a bootloop or any other issues!
Though to avoid any issues I did a factory reset and Cache wipe! Becasue anyways my DATA was wiped completely!
Thought to share this.......great for newbies who wanna flash stock and root it easily!
Nexus 4 unbricking
i had problems with my nexus system since cm11 snapshot 10 (self rebooting etc.) so i decide to ultimate format all my data by doing that:
Wipe data/factory reset
Wipe cache partition
Mount and storage>Format/system
Mount and storage>Format/data
Mount and storage>Format cache
Mount and storage>Format sdcard
Advenced>Wipe dalvik cache
So i have a problem because i cant turn my device into usb debugging mode.
I would like to know if I can save my phone ?

in recovery\advanced\restart bootloader it says "root access is missing. root device ?" so i choose yes

i just manually flashed using android sdk , wiped everything > userdata , cache , system ... it still stuck on spinning dots
anyone ?
Long shot but you might have a similar problem to mine: http://forum.xda-developers.com/nexus-4/help/soft-bricked-nexus-4-guide-t3287284
So far, I haven't fixed it. I'm stuck using 4.2.2 because it's the only one ROM that will actually boot.
Maybe erase userdata in fastboot?
