bricked? red flashing led

Just got my nexus 4, and after it was left in cwm for about 10 minutes (while I was making breakfast) it went to a black screen and now just the red led notification led is flashing whenever plugged in, and on my mac in system profiler it shows "composite device", any suggestions?
Thanks!

Don't know if you want to do this, but you can open the phone and disconnect and reconnect the battery connector...

What was your battery level, I know in other devices some times the CPU(s) run at full speed in recovery allowing for quicker flashing this could discharge the battery rapidly. Also a flashing red LED when plugged in normally means the phone is charging but doesn't have enough charge to reliably turn on, leave it plugged in for about 15 minutes and try turning it on again.

Try holding down the VOL + and - keys along with the powerbutton (after turning it off by holding down the power button for an extended time) and see if you can get into fastboot. My friend's Nexus 4 kept bootlooping after he unlocked the bootloader but booted straight to CWM after, not letting it erase userdata first.

I have no problem doing this, the phone seems easy to disassemble, looks alot like a overgrown iPhone 4, 2 screws on the bottom. I just hope its an easy slide, I don;t want to mar it in case I have to exchange it.

I thought this as well, its been plugged in for at least an hour now.
Oh and now I don't even get the red led!
good times..

I've got the exact same issue. Plugged it in last night to charge and this morning it wouldn't turn on. Plugged and unplugged it and the red LED starts flashing. After a minute or so I'm getting the battery charge animation on the screen - so the red LED is power related. Now to see if it actually charges up and boots.

Hi nycbjr. I have seen a similar issue posted here, but I can't find the thread at the moment, try searching. If I remember correctly then he got it working by holding power, volume keys and then plugging in the charger.

Here seems to be a similar thread, maybe you'll find help there.

I think I'm bricked?

I thought I'd clean up the OP for folks who got here with similar issues as me since it seems more common than we'd like.
Scenario:
Phone does not turn on without the charger or USB plugged in.
When plugged in, it boot loops at the Google logo (i.e. turns off at the logo, and reboots) and gives what is beginning to be referred to as the the 'red LED of death'--where the LED just blinks read.
The bootloader is accessible when plugged in. But trying to boot into recovery causes a loop. If you try to enter recovery, the phone has to turn off then boot back into recovery. But turning off means that when it turns on it will loop at the Google logo. So, booting into recovery is NOT an option.
Download mode is also accessible when plugged in.
Since the bootloader is accessible, it is possible to flash the factory image to the phone, however, doing so does not resolve the boot loop, nor does it allow the phone to turn on without being plugged in.
Fixes which have worked for some people
Instructions in this post worked for a couple people. NOTE: you have to be able to get into the bootloader for this to work.
One person who left it in download mode plugged into the PC (which was off) overnight, and somehow the problem was resolved. Thread here.
Here's a post in this thread from a user who was able to get it booting up again by leaving it on the charger for a bit.

You fool.

In sum: I started using the Faux kernel with AOKP. OC'd to 1.6Ghz and started Antutu. Phone crashed and now it doesn't boot. When I plug in the charger, there's the battery icon with the lighting bolt which I think indicates that the battery is dead. But it's not dead, it was around 95% when I started Antutu. So, it's constantly turning on and off showing that battery icon while plugged in, but doesn't start up. Anything I can do about this?
Also, the computer only detects it briefly, before the phone turns off again, so ADB/fastboot/toolkit seems out of the question, because it doesn't stay detected long enough to do anything.

Tape the power button down so it goes into a power cycle. Leave it until the battery is totally dead. Then plug it into the wall outlet, let it fully charge. Then try turning it on.

Your computer only detects it briefly? perhaps it'll detect it if you boot into Bootloader mode (not sure if you were able to from reading the OP)
Press and hold volume down, volume up, and power until the device boots. If you successfully enter Bootloader mode you can find steps on how to return to stock here: http://forum.xda-developers.com/showthread.php?t=2010312

i am on the same boat. i already contacted CSR anh they will send me a new one. after flash new kernel and start antutu, the n4 crashed and completely dead.

I'm pretty sure the battery with the lightning bolt means its charging.

I would say try this to drain the battery. Then charge it and see what happens.

So how exactly did the phone brick? Just so everyone here knows what not to do. Is it the kernel that caused it since its still in experimental stages?

Have you tried reflashibg or using your nan droid back up from the recovery console?
Just because our won't not does not mean it is bricked.
It is really ticking me of that many people do not even have our phones and you are exchanging because of ignorance. Surely all these exchanges must impact stock. I know they keep extras but how many?
Stop messing with things you know nothing about until you at least learn..

That's the point. It'll turn on and off until the battery is ACTUALLY dead. Then, charge it fully, and try to start it.

Dude this happened to me last night! Same ROM kernel combo! And fired up an tutu after ocing point is this should not be happening just made a thread and seen this here! Freaky! I'm telling u people beware something is up for sure been doing this a long time never seen this before

First if you have an unlocked bootloader, your replacement won't be free. As soon as Google gets it and realizes it's unlocked they will charge you full price for your replacement.
Second, Nexus devices are next to impossible to brick. There is probably a way to reset the device. I would try first unplug the device from your computer or charger and try holding the power button for a full 15-20 seconds. Then try booting into bootloader or recovery. If that doesn't work, try holding volume up and power for 15-20 seconds. If that doesn't work, try volume down and power for 15-20 seconds. And if that one doesn't work try holding all 3 down for 15-20 seconds. This sounds like a problem that would more than likely be fixed by removing the battery and rebooting. Since this doesn't have a removable battery there has to be a built in 'hard reset' that will power cycle the phone.
I am willing to bet there is a way to get this working. I guarantee if I had it here in front of me I could.
Also, like someone else has said before, if you are a not good at diagnosing problems, troubleshooting problems, fixing this kind of stuff on your own and adb/fastboot, it makes no sense to be using experimental software on your device. Especially if you plan on pushing its boundaries by overclocking and running benchmark software. If I were you, after you get this straightened out, wait a while until stuff is more ppolished and tested better.

So, by sheer luck, I was able to get into the bootloader and have it stay on. I was then able to use the toolkit (option 9) to flash the google factory stock image. This completed successfully, and I was also able to re-lock the bootloader, but I still have the same problem as I did before: battery charging icon and constant reboot. So, it's completely stock now and the issue is still there. Would it be reasonable to assume that the issue isn't software and I somehow got a hardware failure?

Yo hold power down then plug USB in then right after hold all three button .like after u plus in USB while holding power button then at same time hold volume buttons also this is how I got into download mode.....but.....phone was not detected and comp SD there was a driver failure. But yes dude phone was charged. And I had same exact combo as u I mean same exact. This is why it is freaky. Aokp was fine all day then when I flashed faux test kernel and fired up antutu I just had a flash then nothing. Not blaming anyone of course it was me who chose to flash after all this is custom software and I love these guys work just wish I knew what did it ....like what actually did it

Seriously... thousands of people waiting for the phone to become available, and people who deserve to have their phone bricked are getting 2nds for free.

I was able to do the same thing but it would vibrate then see Google for a sec then nothing and back to a blinking red light....dude this is crazy I can't. Believe this happened to another person the same exact way

dammit. And I was just going to try this combo. Guess that's gonna be a no go.
Last ditch effort is to unscrew the two t5 screws at the bottom and do a real battery pull. Probably wont work, but what do you have to lose?

[Q] My Nexus 4 won't charge or power on and I'm looking for options

So, a bit of backstory first ( Feel free to skip this part and read it after my TLDR and QUESTION portion for reference)
One day a few months ago (the day that my nexus 5 arrived early, luckily) I was working on flashing a new ROM to my nexus 4, and something went horribly awry. I got error messages saying that something could not be accessed or mounted or something (Sorry, the details are hazy , but it amounted to what seemed like an inability to access the files or locations it needed to access to flash the ROM)
My phone would not , no matter what I attemped , flash a ROM or revert to stock correctly. (I tried a bunch of different ways of pushing files manually to the phone, flashing stock images, etc.) .
Now here's where things get weird. I have NO idea if these two issues are related, I just assume they are. All of a sudden one day (I could never boot past recovery , so I hadn't been paying attention to battery level, considering the phone was plugged into my computer most of the time during those couple days) the phone just shut off.
I seemed to be able to get it to charge, but it never really lasted very long and would unexpectedly turn off again while I was trying to fix it.
That was a few months ago. Yesterday I opened the phone up for the first time, Unplugged the battery, checked connections and everything for possible water or other damage. Even gave the USB circuit board an alcohol bath for good measure. Put the phone back together, and tried plugging it into my computer and what happened was that the computer made a sound like it recognized a device. On the phone itself, a red light came on for a couple of seconds and turned off.
It still won't charge or boot into recovery/bootloader. Doesn't really give any indication that it IS charging, and every time I try turning it on, all I get is that red light that comes on for a couple seconds and turns off.
TDLR: Nexus 4 is messed up at the software level, and on top of that, won't charge or turn on.
QUESTION: Assuming I can't figure out a way to actually fix it, would it be a logical move to purchase a nexus 4 with a broken screen on ebay and pull all the internal components (specifically the main circuit board and battery probably) and put them into my current nexus 4's body?
I have no idea how much it'd cost me to have mine fixed, so I'm kind of just looking for a cheap way to end up with a working nexus 4.

In my opinion if it doesn't boot at all or lasts really little, you should check the battery. Unplug the phone from computer, Unplug your battery and let it off for a couple of minutes. In the mid time just press the in/off button for a few time and few seconds each time, so the components discharge. Replug your battery and let it charge for a couple of hours, not on computer but on the wall socket.
If after that it boot to bootloader the flash stock image.
If not see if you can get a new battery. Sometimes batteries discharge so much from being unused that they won't recharge without help ( need to have Power Supply unit).

[Q] Help! Nexus7 won't turn on!

Totally new here. got my nexus 7(2012) since nov 2012. This morning, I was chatting with friends and my device suddenly froze for 10 mins. i couldnt wait long so i restarted it by holding the power button. now it won't open even if i did the power + volume keys, nothing appears. even when i plug it in the wall charger or on my pc and laptop. still no charging logo or any indication it was on and my laptop says installing new device but always ends up failing so i cant back up my files from my device. I'm not a techy person so i made absolute no effort to root my device. just chatting and some occasional gaming. Please help can't afford to buy a new device for a long while
*btw its a 32gb nexus 7(2012). not sure if this additional info is helpful or not.

Do you get any sort of screen when you try to turn it on ? I.E. do you see the Google logo for a few seconds? Or do you see nothing?
My guess is with a hardware failure or your battery has come loose. When my battery becomes unplugged, I will see the Google logo and then a bunch of funky colors and it will reboot constantly when plugged in. It dies if unplugged, and It also turns on the second it is plugged in.
So if you suspect the battery, there are videos on YouTube to walk you through popping the back off along with pushing the battery back in. I used black electrical tape to hold my battery in place better once I confirmed that was what my problem was.

I would check to see if the battery connection came loose. Its an easy fix to try and was your tablet overly hot or any bulging?

i am so sorry for not replying. i know its too late now because i was asking this info on another thread. i i already tried removing and reinserting the battery on my device.
the nature of my device is that its all black screen. even when you charge it, theres no charging animation that shows or any backlight. its like its really off without anything plugged.
when i plugged it in the pc under device manager, it says apx mode. kinda depressed cuz i think the device is already dead cuz i cant even do the power button + vol down thingie :crying:.

Try pressing and holding in the power button for a long time, up to a minute.

[Q] Nexus 7 (2012) dead. Just flickers

My Nexus 7(2012) 16 gb appears dead. Was on CM11 with TWRP recovery.
Here's what happened :
I was using my N7, the screen froze for a second while scrolling on the browser.
After that a dead black line appeared permanently in the middle of the screen(horizontal).
I figured it might just be the case of dead pixels.
I continued using it like that only.
After a few weeks of usage, now the device won't power up at all.
When i connect to the wall charger, i just get a back light. No display. Nothing.
I tried booting into recovery, but nothing appears on the screen.
I kept it charging for few hours, but no luck.
It only flickers when connected to charger. Disconnecting the charger causes no activity what so ever on the device.
Nothing happens if i connect it to computer via usb.
Any solutions i can try?

Press & Hold the power button for at least 10 seconds while plugged into a power source. If no signs of life after completing the above step my first thought would be a faulty board..

Its just a black blank screen.

Well, I would hate to be the bearer of bad news but it appears your device had a critical failure and is now dead... Obvious answer right? HaHa
RIP Nexus :crying:

You can always try and leave it to charger for a day and see if you get some life to your nexus. I had similiar thing with my nexus, I was actually booting new ROM and then it did some flickering and got blacked out. After connecting to charger nothing happened, just random flickering. I was able to recover and get it back in bussiness when I woke up next morning (it had been charging over night). This was almost a year ago and atm I'm writing this with the same particular device. So give it a shot again, you might still get it back to work. Also you could try to boot the device to fastboot mode by pressing power+volume buttons at the same time for a while. Good luck, let me know if you were able to get it boot&work again!

You could also try popping the back off and make sure the ribbon cables for the display are seated properly. While your there check the battery cable.
