My stock, un-rooted, Nexus 4 decided to stop working today. It just got stuck at the X loading over and over again. I'm trying to flash a recovery and fix this, but I can't get the bootloader to unlock. I type in fastboot oem unlock, which gives me the option to unlock. As soon as I reset however, it becomes locked again automatically.
I've also tried flashing recover right after unlocking, but it gives me an error and says remote: flash write failure.
Any ideas?
I've seen this when the emmc has gone bad. Bootloader won't stay unlocked. I don't know if you're still under warranty but that's your best option

When I boot the NS the screen shows a lock icon which shows it to be UNLOCKED.
I'm downloading a STOCK ROM which says I will loose root, which is okay. BUT, will the rom also lock it again so I don't get that lock icon?
If it won't can you please tell me or link to how I can get it to true STOCK.
Best buy told me I can return it but they said they won't accept it if it was rooted.
Thanks for the help.
Fastboot OEM lock should be all you have to do.

awesome, thank you!
Also, if you want, do fastboot oem lock, fastboot oem unlock, and then lock it again. The unlocking command wipes your sd card.
If you really want to be paranoid look up how to use Odin and flash the stock image with that

I'm considering returning my Nexus 7 back to best buy but I was just curious if there is any way for them to know if the device is unlocked. Do they actually boot it up to the bootloader and check at the time of return? If so, is there any way to unroot the device and lock it back up?

They will likely go into the settings to verify the device number is the same as in your receipt. They won't go into the bootloader but will see the unlocked icon as the device is booting up. You can return it to them with it already on.

Why not just flash the factory image (boot, recovery, and system) and then lock the bootloader?
How do you lock the bootloader?

The reverse of how you unlock it. In fastboot mode type "fastboot oem lock"

I did an exchange at Best Buy. They only made sure it turned on and worked. I didn't even have my receipt, they looked up my credit card number.
May I suggest at least put the stock back, even do a factory reset.
Just look out for the next customer who may buy it.
It's okay, I actually was able to restore the factory image and lock the boot loader back up. Thank you guys.
A lot of times I returned something to bb, they didn't even check the contents inside, they only asked me the reason for the return. Do keep in Mind that they track customer returns based on the id you give them.

During the last two days I overcome the problem of mass boot loop on nexus 4 without success.
The device enters bootloop after regular restart that was done because I lost service.
Before that I had a problem that during a call the screen would turn off.
I did not root or any other manipulation device. Since I bought it (two weeks ago), he was upgraded to 4.4 OTA
I went through the posts on this forum and also online.
I've by fastboot, Flash of recovery; boot; system; radio; userdata. Well also downgraded to versions 4.2
I changed the recovery to CWM still no success.
How ever in the CWM recovery I was able to flash Hellfire (HF) ROM via "adb sideload"
after i did the wipe I restarted, the boot animaton has changed to the one of HF and a message stating that Android is upgrading: optimizing apps and then starting apps. at this point the device was stuck.
after a restart I am stuck again in the bootloop.
how should you proceed now?
thanks
Try to boot into recovery and wipe everything. Then flash rom. Let me now how it goes! Had the same problem last week...
Hit thanks if I helped you
Already tried that
might try a different ROM
If you unlock the bootloader in fastboot and then reboot the device back into the bootloader does the bootloader stay unlocked or does it lock again?

The bootloader remains unlocked. when I run "Fastboot oem unlock" the return line indicates that it was already unlocked.
also the lock state is unlocked (red line on the bottom)
Okay, thank you this was a test for a bad emmc (memory chip). I'll see if I can think of something else you haven't tried.

You'll probably have to go thru LG. I know a guy who's a guru at this type of thing on the n5. Maybe he can help on the n4 @bitdomo They're very similar devices

I only can speak warranty in the EU. It maybe different in the other parts of the world.
If the phone is originaly from google playstore you have to talk with google. If the phone does not come from google plastore originaly then you have to talk with LG. To take your phone to LG to repair your phone under warranty you will need the original receipt with the imei number printed on it from the store it was bought. Also keep in mind if the phone comes from GSM shop or then those GSM shops does not give you LG warranty just shop warranty which means that the phone have to be taken back to the original store with the original receipt. These stores sells phones only with 1 year warranty.
I forgot to mention, if the phone is from google playstore originaly then the warranty is only valid in that country's google playstore which the phone comes from.

He could try this if he has patience and determination. This wipes everything and rebuilds the partitions.
Update
Tried everything, no success, more over when I came back to try and work some more on the nexus 4 I noticed the screen was broken (haven't touched it the last 2 days...) finally gave up.
I got a full refund from the Ebay supplier
Still very disappointing, Ill chuck it all up to a faulty device
I am experiencing with a soft bricked Nexus 4. Surely, I tried to do "Power + volume down" and tip on the internet. But, it did not work for me. my cell is on the bricked. For now, there is no way except for "reset to facory". But, I did not data back up. It's my dilemma. :crying: First of all, I should try to save data to my computer.
If my computer is broken, I can take the HDD(storage) out from that, and save data using connecting device like "SATA to USB". As Nexus 4 use only internal storage on (maybe, flash rom?)the board, I can not take it out.
Is there any way to save data from a soft bricked Nexus 4?
I found one thread have the same problem. My symptoms is the same as his
--------------------------------------------
the phone boots, shows the google logo then goes into those 4 colourful dots that fly around and it just stays like that. I left it like this over night and nothing happened.
--------------------------------------------
I am referring to the answer. So, I try to do wipe cache on recovery mode according to that. It doesn't help me.
Thanks for any other tips or comments in advance.
Is your bootloader unlocked? If it is flash a twrp.img file. Boot into it and you'll be able to connect your device to your pc and transfer files.

Unlocking your bootloader will wipe your device. So in your case it's not an option. You're probably going to have to give up on your data and lose it to get your device working again.

Thanks jd1639.:good:
After reading about unlocking bootloader, unfortunately I get to know that will wipe all the system data and my data on my device. It's the same as what you comment.:crying:
A couple of years ago, there was an application program for Rom Flashing called Flashtool. I could do that with unchecking option "wipe user data". Surely, to back up data before that was strongly advised though.
Maybe, due to security, it seems to be impossible on recent version. I
am anticipating for any other idea to save data before get it work again.
Thanks in advance.

Stock, up-to-date. Using my Facebook app, and phone seems to freeze. Black screen, with Google. I can access bootloader, but NOT recovery mode. My warranty expired like 5 days ago. Am I SOL?

If your bootloader is unlocked you may not be. Search for items you can Flash to fix the bootloop issue. I don't have the URL handy sorry. If your bootloader is locked you might be in trouble. There are some tricks in the same fix post to tell you how to try to get back into your phone and then once you do get the bootloader unlocked quickly so you can load the fix

Yeah, I never unlocked the bootloader. I let it sit for a few hours, turned it on for S&G, tried and succeeded to get into Recovery mode for a few minutes, but because I forgot the way to access the menu. It dropped back into the bootloop. Going to try again in a few hours, now I know how to access the menu, I'll try wiping cache.

If your not gonna send for warranty I would unlock your bootloader. Also get your hands on the 4 core modified boot for your Android version. Find out more in the BLOD thread.
