Nexus 4 caught in bootloop after installing 4.3 stock. Help? - Nexus 4 Q&A, Help & Troubleshooting

I have a stock unrooted Nexus 4 that is caught in a bootloop after trying to install Android 4.3 from the OTA that was sent out. The phone was fully stock, nothing was done since it was pulled from the box and turned on.. So far I have done a cache wipe and factory reset via stock recovery and nothing worked. Any help trying to recover from this would be greatly appreciated.
I'm installing ADB on the new computer as I type this.
Thanks in advance for all the help.

I think you should flash the factory image following efrant's guide if a cache wipe doesnt help.

I can't power the phone on to turn on debugging so ADB is not recognizing the device being attached to the computer. Any ideas?

I tried going through the guide but I still could not get ADB to recognize my device. As I am reading the guide it even says that I need to type in command fastboot devices to verify that my device is being recognized which it is not so I'm not sure what to do. I didn't get very far with Google tech support and the warranty replacement center wants to put a hold on my credit card for the amount of a new phone till mine gets returned. They won't just let me send mine in and then send me a new one which is ridiculous in my opinion. They are telling me that my only recourse is to send it to LG and have them fix it. Very frustrated with Google right now.

[SOLVED] Unbrick Nexus 7?

Hey everybody,
Yesterday I tried flashing a theme to SmoothRom and got caught in a bootloop. In a panic, I accidentally factory wiped my sd card and lost my roms so now I can't flash another rom to my Nexus 7. I've tried adb pushing a rom to the sd card, but my Nexus 7 is not being recognized in adb devices. I've tried everything to my knowledge but I still cannot get anything to work, even tried working on Mac and PC computers and my Nexus won't show up in adb.
I'm ready to count my losses as it is my fault, but I figured you guys could help out. I love my Nexus so if you guys know anything I could do I'd greatly appreciate it. Thanks.

Yeah I can still get into fastboot & recovery (Clockwork mod touch). I've tried mounting the sd card in recovery but nothing happens. Tried doing adb to sideload a rom but my device is showing up.

Re: Unbrick Nexus 7?
You can go two ways here, either you can do as the above user posted and flash a stock image via fastboot or if you have a otg cable and a pendrive/removable media you can use that to install the rom

Ok guys, I spent all last night trying to get this to work, and I'm still having problems. I tried adding the line to the driver inf file but nothing worked. I tried adding the PDANet drivers, but the Nexus of course is not showing up. I know that my Nexus is not doomed it's just something I'm not doing right, not gonna give up I'll keep at it. Thanks for the help guys, if anything have any suggestions let me know!
Sounds like you should find out if CWM touch can mount a USB flash thumbdrive via an OTG cable. You can avoid driver problems that way (as long as it works). The filesystem formatting of the USB drive with the highest probability of success will be a FAT format.
good luck

There's nothing wrong with it... you just need to flash stock with fastboot or adb sideload it.

Wipe data again, wipe cache, wipe dalvik cache, and re-flash SmoothROM.

Somehow I have screwed my nexus 7(16gb wifi only) up so bad that I cannot get back into fastboot or recovery mode. Any attempt at bootup is met with a blank screen. How do you suggest I proceed?

If fastboot is really dead, then you're out of luck. Have you tried running fastboot commands, however, after trying to boot into fastboot? Sometimes the underlying software will run correctly, even if the screen is nonresponsive.

So I assume this means my only hope is to replace the motherboard which houses the memory. Is that a good assumption?
HELP!
so i had the same thing happen to me. I had access to recovery still but instead of re flashing i tried to use nexus root toolkit to factory reset. somehow fastboot failed halfway through and now recovery is gone with everything else. The only thing i can get into is the bootloader mode....
My device is still listed as a fastboot device, but when i try to re-run the flash to stock i get this: (see attached picture)
Please help, I honestly have been working on this for days, but i simply do not know enough to fix it!
I will post a new topic if no one responds. Thanks

I'm having a similar problem. Present state of the device is that my N7 boots into the bootloader and then to the custom recovery. I've accidently erased the OS.
Can you tell me how you managed to unbrick via OTG. Should I move the factory image to usb flash drive and then mount it via OTG and then try to flash it via recovery???
Please help:crying:

Greed lead to Brick!

Hey guys
I thought I'd just let you all know that my ambition to get 4.3 and lack of knowledge, led to my phone getting bricked today. I'm so devastated. I was following efrant's guide and flashed everything correctly and then as usual I lost half my storage and I followed the other guide to restoring the lost storage, once again i followed everything but i didn't get the storage back, then i did some cmd commands like the guide did. Next thing you know I may have done something wrong and I was at the bootloader screen and I couldn't reboot or go to recovery. Read and read nothing helped, called Google and they couldn't help me. I am now getting a replacement. SO there you go guys, just the greed of getting 4.3 caused me to brick my phone as well as my lack of knowledge I guess. Can't complain. Thought I'd share this with you all.

In this particular situation i wont recommend you using a toolkit. Is much esier with a good guide if it fails with the toolkit (btw while i flashed 4.3 factory image the cmd told me also about "missing recovery and system.sig" but now ive got a fully working 4.3 ROM on my N4.
You can do it via ADB. You just setup ADB on your computer. And put all the files from the factory image in the "platform-tools" adb folder. If your phone is in the bootloader menu and its recognized by your computer you just run a file that is called "flash-all.bat" and it should flash the 4.2/4.3 image on your phone. Thats how i did it a few hours ago.
Have a look at this guide: http://forum.xda-developers.com/showthread.php?t=1907796
But remember all the files in this guide are for the Nexus 7 so use the N4 factory images and the proper commands for your device (i mean the last step of this guide which shows various commands. you shouldnt use them becuz they are for the N7 and the proper commands for the N4 are written in the "flash-all.sh" use those commands or use the "flash-all.bat" which is included in the 4.3 factory image [i dont know if its included in the 4.2. f.i.]. All those files have to be in the "platform-tools" folder in order to let the .batch file do its job.
I hope u understood what i wrote. If not let me know.

I have also a phone that is dead after the upgrade. It was just "looping" on the "Updating Apps" screen, so I turned it off, now it won't start. When the "Nexus X" apperas, it just loops on this screen and nothing happens...
I would very much like to keep pictures and texts before resetting the phone! Can I do that in any way??

Flash ClockworkMod or TWRP and using one of them wipe cache, dalvik cache and data (not storage). Apps and settings will be gone, but your music and pictures will still be there.

Oh well you should look in one of those threads on how to root and so on, flashing a recovery using a toolkit should also work. Texts will be gone.
Or from this thread: http://forum.xda-developers.com/showthread.php?t=2010312
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.

But at some point you'd need a custom recovery anyway.

Nexus 4 No OS Installed TWRP

Guys I need your help.
I have Nexus 4 16GB pre owned. Bought it with Cyanogenmod 10.2 installed already and rooted. Then CM11 nightlies came and I installed it OTA but it seems that it has a lot of bugs so I rolled back to CM10. When I rolled back and rebooted, it does not come up (Google and Cyanogenmod logo only). I rebooted it to bootload mode, then recovery (TWRP) and accidentally wiped out everything including ROM/OS. I don't have that much knowledge in restoring my phone. I tried connecting it to PC (WinXP) and it does not recognize the device. Tried everything posted in different forums on how to connect my device to PC but to no avail. Cannot do USB debugging thing 'cause I can only utilize device's recovery mode (TWRP). I'm thinking now on having this device repaired by cellphone repair shop just to install OS.Anyone can help? Other forums look like too technical for me. Noob here, really.

Can't recover tablet

hey guys
I decided to flash back to stock today and recovered my backup but it wouldn't boot so I turned the tablet off and put it into it's bootloader and tried to flash a stock image but fastboot refuses to flash anything to the tablet at all :/ i can't at this point boot into anything any help?
I can for some reason put the userdata on and off but nothing else will flash onto the tablet :S

Yeah I know all the commands and stuff and how it all works I've been using fastboot and adb etc since launch of the nexus 4. There's no output the commands just stop for instance when I use the flashall.bat from the factory images it wipes everything but won't put anything actually on the tablet it just hangs at the first sending and never finishes it just hangs there.
I've tried flashing the files manually swell but again they won't go on. The only thing that does finish is userdata.img but nothing else finishes going on the tablet at all turning on the tablet it vibrates twice and just boots onto the bootloader and nothing else opens not even the recovery
EDIT: Hooooly smeg it actually started working! it's alive again
Not trying to say you don't know, but the more information you give the better your help would be
Knowing what bootloader you have and if unlocked or not will help determine proper steps
Knowing the exact input/output can help as well as knowing the os you are using
Also if tab was working 100% before the attempt to return to stock, prior recovery and rom, any other issues you have had, etc
But its fine if you don't want to post this
Next steps would be
Make sure fastboot binaries on PC are up to date
Quality USB cable
Check md5sum for files you are to flash
If manually flashing stops at sending what happens when you manually erase?
What happens if you just try and boot a recovery through fastboot?
The more info you are willing to give the better your answers will be

It's all ok for some strange reason on the 50th odd attempt it finally started taking the data from fastboot. for some reason before hand when I tried manually the command would just sit there as "sending recovery" or whichever i tried and wouldn't move even waited 20 mins earlier just incase. i'm not sure at all what was happening there but now it's booted and fine

Random bootloops! Fastboot detecting device but not adb!

Hey there,
My phone started bootlooping this morning out of a sudden.
Tried going to recovery to wipe cache etc but not booting in recovery.
Tried adb commands but the phone doesnt detects itself.
Surprisingly/be default the phone is recognised by fastboot commands.
I have some important data in my phone would be glad if it is saved.
Else have to make do with whatever is necessary to bring the phone alive.
When connected this is what it looks like.
Please guide .
Thanks in advance.
You just described the legendary Boot Loop Of Death or more commonly known as BLOD. In my experience with my phone, no way to get anything from the phone once it's in this state. There is a great tutorial by Heisenberg on here. Maybe on of the chapters addresses saving data. Once you give up on the data, do a flash-all.bat using a factory image through fastboot. If you get no errors but continue to boot loop with no access to the recovery, your most likely looking at RMA as your only option.

Still bootlooping.
My phone is out of gurantee so rma is out of question!
Any other suggestions?

Try pressurizing Huawei and hear what they say.They should be knowing about the issue.
Several people have talked then into doing the RMA by referencing the hundreds of people talking online about it. Just ask them how they can sell a faulty device and not support it.

It's normal for ADB to not work unless you are in recovery mode. Without ADB you cannot push/pull files from the device. Try to fastboot flash or fastboot boot a TWRP recovery image from your PC. Any errors? Sorry, but If you cannot access recovery mode you are "dead in the water". Options are to start over with a new phone or source a used 6P and swap the motherboard. One guy in Korea found a used one for around USD $60.

It does flashes fine without any errors.
Doesn't boot into it though!
I was able to boot to recovery mode for once last night but didn't do much help although made me more optimistic about it.
Will try tinkering around more before giving up.
I'm actually flashing every google official image to see if it works on any version.
Will post the result soon.
One more thing if you see the screen shot I posted originally the last shows "Connect USB data cable" but it doesn't shows connected status even though it does gets detected and fastboot command works well.
