Boot loop / blank screen - Nexus 4 Q&A, Help & Troubleshooting

so I could use some major help! I received my new nexus yesterday and I believe i've already soft-bricked it somehow but I can't seem to recover it. I've read that you should change the APNs from the cingular ones to the new att settings. I did this, and then I rebooted phone, but somehow it got stuck in a boot loop. so i was like S%^T, and all. so like a moron I started messing around in fastboot and I unlocked the bootloader through cmd line. I found this article http://forum.xda-developers.com/showthread.php?t=2010312 which I figured was my best chance for a recovery. I also tried the Nexus Root Toolkit v1.7.1 and told it i was softbricked / bootloop scenario. I've tried loading the twrp, cwrm, stock recoveries, but evertime I try to boot to the screen is on, but blank. i dont get the android with the !..
NOTHING is working!
I think my major problem at this point is i NEED usb debugging enabled, but I cant get into android gui itself to enable this option.
Believe me ANY help is greatly appreciated and I'll but you a pizza and have it delivered to your home...:laugh:

This should be easy, just put your device on bootloader and use this tool, make sure you have the ADB and Fastboot files with it all.

Done this also. I used the 4.2.2 files for Mako. Then followed the link instructions that I posted from that link.
1) Make sure your computer recognizes your device by typing: fastboot devices
2) Unlock your bootloader (if you have not already done so): fastboot oem unlock
3) You will see a prompt on your device. This will wipe your entire device (including the /sdcard folder). Accept. Note: you use the volume keys to change the option and the power button to accept. You cannot use the touch screen.
4) Reboot by typing: fastboot reboot-bootloader
5) Flash the bootloader: fastboot flash bootloader bootloader-mako-makoz10o.img (or whatever the name of the bootloader image that you downloaded).
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.48.img (or whatever the name is of the radio image that you downloaded).
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system system.img
10) Flash the data partition: fastboot flash userdata userdata.img Note: this command will wipe your device (including /sdcard), EVEN if your bootloader is already unlocked. See note 2 below.
11) Flash the kernel/ramdisk: fastboot flash boot boot.img
12) Flash the recovery partition: fastboot flash recovery recovery.img
13) Erase the cache partition: either a) fastboot erase cache OR b) fastboot format cache <<== the second option seems to work better for most people. Thanks joostburg.
14) Reboot: fastboot reboot
15) Done! The first boot will likely take quite a bit longer than you are used to, as Android builds the Dalvik cache.
At step 8 it doesn't reboot saying it failed and I have to hardboot back into bootloader from every step forward where required. Eventually I can flash all the img files and reboot phone. I'll then see and android logo with a blue rotating sphere and status bar, then reboots. it does this several times then screen goes blank.

Well I was able to run the "flash-all" batch file with success, no errors or bootloader reboot issues. Phone rebooted again and now I'm suppose to be waiting for Dalvik Cache to rebuild. This is about 10 mins ago though, any ideas how long it takes to do this??

Should take around 10-15 min. If its taking more than 20 minutes i would suggest going into the bootloader, then into the stock recovery and doing a factory reset from there.

USB Debugging is just really a ADB switch for the OS.

Nexus 7 wont boot pass google logo after root/unroot

I got a nexus7 a week ago but decided to root the device today just to try apps which require root, i rooted it fine but i decided to unroot and thats where the problem started i cant boot pass the google image, i can get into where you hold down volume and power for so many seconds and team win recovery which says i have no OS in the reboot section, i've tryed nexus 7 toolkit v3.2.0 and nexus root toolkit to restore back to factory system but no luck, so is it me doing something wrong or is my nexus 7 just a paper weight now.
Doubt it,
Being you still have a custom recovery you didn't follow the right steps to unroot, might need to unlock the bootloader again, but follow one of the many guides, and try to stay away from a tool kit

Unlock bootloader
Flash boot, recovery, system, userdata.
Files are zipped in the factory images directly from google.
Wipe cache.
Relock bootloader.
Reboot into recovery.
Factory reset. (Nexus 7 will only see 8GB if you don't do this step)
That is the gist of how it's done.
I followed a step by step guide on laptop man website but when i come to flash the android image it says file too large, i used 4.2.1 from googles site, if i'm correct when you type fastboot -w update image-nakasi-jro03d.zip (in the walkthrough) i can replace it with a later newer android in this case 4.2.1 jop40d
You could do it that way. Some people have. Although I received an error every time I did.
I didn't receive an error when I flashed the files in the zip.
First make sure you have the correct factory image for your device downloaded.
Then make sure you extract the boot.img, recovery.img, system.img, and userdata.img files to your fastboot folder and perform the following actions...
fastboot oem unlock
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot reboot-bootloader
fastboot oem lock
Lastly, boot your system up into recovery and perform a factory reset from there. If you don't do the last step they you will be stuck with ouly 8GB, vice 16 or 32.
It's that easy.
When i try to boot into recovery mode i get the android mascot with a red triangle, does that mean i have no recovery file.
OOOPS the system booted up into android as the recovery mode didnt work (as above) is there anyway i can reset to factory settings to get the 32GB back as it shows 6GB.
Update: I think i sorted it out now somehow as it shows up as 27.oddGB now (about same as i got it) instead of 6GB, anyway thanks for your help, it seemed complex well it is but once you know whats what it's not so, the hardest part is getting the files and putting them in the right places
When I try to reboot to recovery via the bootloader it just hangs... Can boot to recovery inside android (usually using Rom Manager or another reboot application)... any idea why?
I have read reports that it will hang when booting into recovery if not connected to a PC.
And as for that triangle you see.... That's normal.
That means that your in recovery mode. Your menu is just hidden.
Press power and volume up to view it.

Updating to 4.3 Image with fastboot failed.

Hi guys
I was trying to update to 4.3 using fastboot and after finishing i got stuck with the google on the screen. So i went on to try it again, this time installing each .img in the zip manually. While i was sending the System.img the usb connection broke and i tried again to no avail. So i was like lets do this again. So i went i started all over again with erasing boot, now the terminal is stuck on that and not going forward. Im out of options. Really need help, im helpless here. Please.
Thank You

Is that a Mac? There is another thread with a guy having issues flashing system.img using a Mac. Not sure if he was able to fix it or not. He was able to flash all the other images just not system.img.
For reference from Efrant's thread on flashing image files if your phone hangs during first boot try this:
Note that some users indicate that they can't get past the X on boot. If this happens to you, reboot into the bootloader and select recovery. Then, when you see the Android with the red exclamation mark, hold power and press volume up to take you to the menu. Wipe cache. If that still doesn't work, boot back into recovery and do a factory reset.
http://forum.xda-developers.com/showthread.php?t=2010312
I had the boot issue when I first flashed the images and just formatting the cache fixed it for me. I later had to do a factory reset as the phone was reporting the wrong storage size, 8 GB instead of 16 GB and the reset fixed it.
Here is the other guys Mac thread, not sure it will help you or not.

And the thing about cleaning caches is locking and unlocking bootloader does the same. Tried, i cant install recovery and system .img for some reason.
Thank you for the quick reply, seems the like the guy is having the same issue. Will post it there as well.

According to this thread when using a Mac you don't flash the system or kernel (boot) images.

Yeah you do. I just did this on my Mac for my Nexus 4 and Nexus 7 last night with absolutely no issues.
The procedure I used is as follows...
1.1) Download the factory image and ensure all .img files are extracted to the "platform-tools" folder
1.2) Boot phone into fastboot mode by powering it down then holding volume down/power at the same time until the fastboot screen appears
2) Plug the phone into the computer via USB cable
3) Open terminal and type: fastboot devices (if it recognizes your phone's serial number you are ready to move forward)
4) Reboot by typing: fastboot reboot-bootloader (I do this just to test the connection but it's not 100% necessary)
5) Flash the bootloader: fastboot flash bootloader /Users/kevin/Desktop/Android/sdk/platform-tools/bootloader.img
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio /Users/kevin/Desktop/Android/sdk/platform-tools/radio.img
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system /Users/kevin/Desktop/Android/sdk/platform-tools/system.img
10) Flash the data partition: fastboot flash userdata /Users/kevin/Desktop/Android/sdk/platform-tools/system.img (Note: this command will wipe your device)
11) Flash the kernel/ramdisk: fastboot flash boot /Users/kevin/Desktop/Android/sdk/platform-tools/boot.img
12) Flash the recovery partition: fastboot flash recovery /Users/kevin/Desktop/Android/sdk/platform-tools/recovery.img
13) Erase the cache partition: either a) fastboot erase cache OR b) fastboot format cache <<== (the second option seems to work better for most people and it's what I used)
14) Reboot: fastboot reboot
After completing step 14 your phone should reboot to the initial setup screen. If you follow those steps vigorously you won't have any issues. If it doesn't work you did something wrong and should start over. If it doesn't work on a second try then I'd re-download the system image from HERE again just to be sure the .img files you are ultimately trying to use aren't corrupt somehow.

In the other walk through flash system image and boot image is replaced by "./fastboot update image-occam-jwr66v.zip". This could help those who are having problems flashing the system image file. I've also seen this method used for windows in that all you flash is the bootloader image then the update image and your done.
-w is to clear the userdata, but the problem is its not pushing the system.img on the phone! Tried without -w and yet the same issue! I have restored my previous rom and madea nandroid for 4.2.2 stock! Might go back to that and try updating ota! Can somebody confirm if i have to lock bootloader and lose root to get an update!
I have no clue why the same steps work for 4.2.2 but not 4.3 image files!

One thing I don't think anyone has mentioned (which may actually be the core solution to this problem for everyone) is that you need to update your SDK Platform from 17 to 18 and you need to install "Android Support Repository" in order for 4.3 to properly flash. To do this open terminal and paste the path to the "android" executable file found under sdk/tools. My path was:
/Users/kevin/Desktop/Android/sdk/tools/android
After pasting the appropriate path into terminal hit enter. This will open the SDK Manager. Once SDK Manager is open it will ask to update outdated drivers. One of the drivers being updated is SDK Platform. Before hitting the update button scroll down to the 'Extras' folder and check the box next to "Android Support Repository". Now hit the update button.
After doing this, reboot the computer (may or may not be necessary) and try flashing again by following the steps I provided in post #5. Let me know if that solved it.
Well, i may try that! But as if now, went to bootcamp, installed drivers and sideloaded 4.3. I may still try updating sdk, just in case i may neeed to do this again!
Where is this sdk/tools?

sdk/tools is located wherever you extracted the .zip file to. In my case I just put it all in a parent folder on the desktop called "Android".

Nexus 4 cannot pass the X screen after uninstalling Ubuntu Touch

I followed official Ubuntu Touch instructions for installing/uninstalling Ubuntu.
Installation went without any problems, but after returning back Android, the device is stuck on the "X" animation and cannot proceed.
I tried the following:
Going into recovering mode
Flashing the device to stock version of Android (v4.2)
Flashing the device to previous installed Android (v4.3)
The flash-all.sh command is executed successfully every time, but boot gets stuck at "X" animation no matter what I do.
What can I do to fix this issue? Any ideas?
Thanks!

Thanks a lot for your answer Alvin - the issue was related to caches. I managed to fix the situation by doing the following:
Going into the bootloader mode and selecting "Recovery"
Holding volume up and power button until a new screen is opened
Do a factory reset
Wipe out partition cache
Do a factory reset again
Everything seems to be working properly now.

Help Wiping (or Unlocking) With a Broken Screen

The screen on my Stock unrooted & locked Nexus 6P is completely non-functional (shattered, not displaying anything, likely not responding to touch) and I'd like to wipe it before disposing of it.
I'm able to blindly navigate to the bootloader but I'm having trouble unlocking for the purposes of
Code:
fastboot erase system -w
.
Process
Boot into bootloader then issue the unlock command:
Code:
fastboot flashing unlock
Because I can't see the screen, I'm assuming pressing up or down will select 'Yes' and power will confirm it.
Either way (up+pwr or down+pwr or just pwr) the phone restarts and I let it sit for a while.
I reboot into the bootloader but the unlocked variable returns no.
I figured the closest analog would be to reflash via
Code:
fastboot -w update "image.zip"
, which will wipe userdata and cache - is that sufficient?
Don't worry....just download and install Nexus toolkit or do it manually by downloading Adb fastboot minimal <10mb size.
First, install driver for flashing firmware.
Reboot to bootloader,
Connect to pc,it will make sound if connected.
Now,put system.img to adb minial folder.
Right click and open cmd in adb minimal folder.
Type adb fastboot flash system system.img
Then,in the middle disconnect from pc.since,it will corrupt your system file.Do this for 2-3 times,that is flashing system.img and disconnecting in the middle to insure that system file have corrupted.
Then,at last flash system.img till end to complete.
Voila...you will have a factory reset phone.
I did this trick before selling my galaxy s5 broken display phone.
When buyer put display in front of me,it was factory reset.

Boot into bootloader then issue the unlock command:
Code:
fastboot flashing unlock
Because I can't see the screen, I'm assuming pressing up or down will select 'Yes' and power will confirm it.
Either way (up+pwr or down+pwr or just pwr) the phone restarts and I let it sit for a while.
I reboot into the bootloader but the unlocked variable returns no.
I figured the closest analog would be to reflash via
Code:
fastboot -w update "image.zip"
, which will wipe userdata and cache - is that sufficient?

Run a drill bit through the upper 1/4 of the screen and through the motherboard then dispose.

Don't worry....just download and install Nexus toolkit or do it manually by downloading Adb fastboot minimal <10mb size.
First, install driver for flashing firmware.
Reboot to bootloader,
Connect to pc,it will make sound if connected.
Now,put system.img to adb minial folder.
Right click and open cmd in adb minimal folder.
Type adb fastboot flash system system.img
Then,in the middle disconnect from pc.since,it will corrupt your system file.Do this for 2-3 times,that is flashing system.img and disconnecting in the middle to insure that system file have corrupted.
Then,at last flash system.img till end to complete.
Voila...you will have a factory reset phone.
I did this trick before selling my galaxy s5 broken display phone.
When buyer put display in front of me,it was factory reset.

Excellent excellent excellent advice - much appreciated.
You need to have USB debugging enabled btw to unlock your phone and issue those fastboot commands.
