[Q] Completely stock device refuses to boot

Firstly, this device has never been rooted or had anything flashed to it. It is completely stock.
My step-daughter has been having issues with her Droid 4. About a month back or so, she started noticing that it wouldn't boot. It would flash the Motorola logo, and then the screen would just hang on the bootanimation. Eventually if we rebooted (power+vol down) enough times it would boot up.
Last night however, this happened again and it would not boot at all. I tried rebooting many times and it would never get past the bootanimation. After about 20 or so reboots I figured it was time for a Factory Reset. After the reset however, it wouldn't even display the bootanimation. It would still display the Motorola splash screen, but after that the screen would just go black with the display is still on. I Factory Reset several more times and nothing. Eventually after a number of times rebooting, it finally booted up. Well that was yesterday. Today she had to reboot it and it wouldn't boot again. Would just hang on a black screen.
I'm about ready to send it back since it's still under warranty, but figured I would check here to see if any of the amazing XDA guru's had experienced this and found a solution. I searched Google and this forum and didn't really see anything. Any help would be greatly appreciated!

Only other I can think to do would be to flash the fastboot files. A factory reset basically just wipes data while fastbooting it should reset the system itself to complete bone stock. You can do this using rsdlite or download a utility like jsnweitzel's ICS Only Utility in the Dev section.
Really sounds like a hardware issue to me since it's not rooted or anything but still might be worth a shot.

Thank you very much for the quick reply. I've downloaded jsnweitzel's ICS Only Utility and am charging up the phones battery so I can use it.
Just a quick question before I do this. I'm assuming that running the restore through ICS Only Utility is flashing a stock system image. That image is not rooted is it? Not that I would typically care, but if I do have to bring it back to Verizon I don't want them hassling me for rooting the device.

Thanks for the help but that didn't do it. Guess I'll be taking it back to Verizon!

I'm in a similar state at the moment and I also have a thread posted about it. I'm trying to see what I can manage my self until someone answers. I work at a bestbuy so I'm going to see if our samsung guy can use his S.M.A.R.T. to reflash it if I don't have anything new by the time i get to work in the morning. I'll keep you posted if you want.

Just a quick update - This thread just worked for me. I'm by no means an expert but It's definitely worth a shot I think.

Possible brick after build.prop edit. Verizon LG G2

Hello,
I've been rooted for a few months now and have never had any problems. I wanted to use that Milk Music app from Samsung so I followed the instructions and was able to get it working on my phone and have been for awhile. I recently decided it would be a good idea to change the build.prop file back to its original state, so I copied and pasted it in using Root Browser. (I had made a backup file stored elsewhere). Once I did that I rebooted my phone for the changes to take effect. After I did that I cannot get my phone to turn back on. It displays the LG animated logo screen and then goes completely black. The light on top of the phone radiates blue/green. I've read through several forums about this issue and have tried everything in order to get it to work and for some reason, using my computer and ADB always gives me an error: device not found. I have installed the drivers and everything. Anyone else run in to this problem before? I would really appreciate it.

If you are on stock rom, just rooted. I would think you should be able to factory reset through stock recovery.
Confirm the process but i think you power completely off. Then hold volume down and power at the same time when you see the lg logo release both buttons then press both buttons and hold them.
Should take you to factory reset.
Not 100% certain but this will probably be your next step if you can't get a computer to see it.
Good luck

The factory data reset didn't really change anything. For some reason I cannot boot into recovery mode either. I can put it in download mode though, but my computer still has a problem recognizing it.

If you can get into dl mode then you should be able to return it to stock which should reset everything. Returning to stock has its own downside but at least you'll be up and running again.

no bs - i took a photo, opened an mms to send it, then the phone bricked itself......

okay so just like you read, i took a photo, opened an mms to send it, then the phone bricked itself. i got a black screen as if the phone was to freeze but then after several attempts to reboot (holding down the power button for long time, pulling battery, etc, etc) i got stuck in a boot loop and this is where i am now.
cannot get into recovery, only download mode.
the phone IS NOT ROOTED. which is what confuses the hell out of me.
i use nova launcher and a bunch of basic apps. nothing has been done to this os other than the launcher and the kernel is all stock too.
can really use some help because i need to retrieve some files off the phone storage.
thanks so much

odin the base you were on and you should be good, you probably somehow got your partition corrupted so you may want to do a clean flash after that

Sorry that you are having such problems. I honestly doubt that it had anything to do with you sending a picture. This looks more like a hardware failure that might be the reason you cannot enter the recovery.
Maybe this helps with the Data recovery. Connect the phone to your computer maybe you are lucky and it gets recognized as a hard drive and you can manually move the files that you want.
If that doesn't work you might want to download the original firmware from your phone (the one that you are using) and flash it via download mode. should that not work try to flash a previous firmware version.
Should none of that work you can try to download just the recovery and flash that and see if that works.
If that doesn't work you might try to root the phone and install a custom rom.
Once you make it into the recovery you should be able to do a reset - however that will destroy the data on the phone.
Good luck with that and you might have to return the phone to be serviced.

Sounds like you tripped the Knox efuse.. Did you? Does it say 0x1 or 0x0 on the bootloader info screen?

The only thing you can do is reflash back to stock using odin. If you want your phone working again. If it boot loops after flashing you will have to start your phone in recovery mode by pressing the volume up, home and power at the same time and doing a factory reset from recovery, but I have to warn you if you have to do a factory reset you will lose all your data. Such as photos, music etc.

Wipe Cache/Data and Factory Reset from recovery.
If not, then you can flash the stock firmware via Odin.
