(FIX) Red Blinking Light of Death

This may or may now help anyone.
I was using my phone and it just **** off on me. I wasn't flashing a rom or "tinkering" with it. I am rooted but was stock. No kernel. Connecting wall charger or connected to PC would just result in blinking red light.
I removed back cover (be careful doing this) and disconnected battery from mother board. Connected it back up and BAM...all is well. No loss of data...turned back on on the state I had left it.
Maybe this will help someone....

I'm 80% sure this has to be cuz of stock charger

did you try first just holding down the power button for like 10+ seconds? I get the red blink of death a lot in my car, I believe it is related somehow with thw wireless charging and it is shorting out or something with another component of my car. Anyway holding down the power button for a while reboots it.

And then the other 1000 that weren't charging or did use a different charger.
I don't believe it's the stock charger

I tried 5 different wall chargers (including stock charger). Three different USB cables on three different PC's. No change in results. Red blinking LED remained. I tried all combination of powering it on...Red blinking LED remained. I literally tired everything for 4hrs straight without any results.
Removing the back, disconnecting battery and reconnecting did the trick. It has been working perfectly for 6hrs now. Charges fine, no issues.

How hard is it to remove the back panel and remove the battery?

Very easy. Took about 3 minutes. I also had access to cell phone tools...basically a plastic separator tool (wont scratch or brake anything). You could also use a guitar pick or a plastic silverware knife.

I just received a Nexus and it is doing this exact thing.
I plug it in with my Samsung Tablet charger (2.0a so plenty of power) and get a SOLID red LED. After about 5 minutes, the Red LED turns off. If I try to power it on (power, vol down and power, all 3 buttons) with AC attached the Red LED just comes back on solid. Unplugged, nothing happens - no matter how long I hold down the buttons. Nothing is working!
Did I get stiffed with a crap device?

What really sucks...if you call and exchange it with them. They will want to hold the purchase amount on your card til they get the old one back.

Unfortunately I purchased this from ebay - just my luck it comes back in the play store the week I finally get one at a decent price! I'm going to leave it charging overnight, but I don't have high hopes. I'm really bummed out.

you gotta carefully take the back off and disconnected/reconnect the battery. that's your only hope.

I noticed my Belkin car charger started wheezing and the phone displayed the charging icon on and off. But disconnected before anything happened..

I have nothing with which to separate the back and that would invalidate any hope I have of receiving a refund from the seller.

If you have paid with paypal check if you have buyers protection.
Then first contact the seller and if he ignores you then contact paypal about the issue.

I'll have a try.

Did anyone tried to not panic and just put the phone for a couple of hours into charger?
if the battery is completly discharged, connecting it to charger for 10 mins will not make the device run, trust me it works the same on Nexus 7.
Put the device to charger for at least half of day (6h) and then check if the problem still appear, if yes then RMA the device (openning it up may break the warranty).

This isn't the problem in a lot of the cases. I've had it happen to me now 10+ times. Sometimes the battery is almost full-charge. I can't RMA the device because I bought it at home (Wisconsin) and now I'm living in Germany.
For anybody wondering, you can buy a nexus from somebody else (as in the e-bay case) and transfer the warranty to your name.

This a "lot" of cases, are simply people who panicked and cant think straight (this is most common issue at Xda developers, especially when rooting phone ). The long charging test is the first thing you should check, if this will not help then its battery fault and need to be RMA'ead. But in most cases i'v readed , it was simply that battery was discharged fully, and phone needed time to charge it back to run device...
You still can RMA your device, it will just cost u more to send/recieve it from Google/LG.
And yes, if you bought a N4 purchased at google play and sold to you, the device ID must be transfered to new owner (old owner can simply send an email to google play). In case it will not be transfered and you will try to RMA te device, the original buyer will get it , not you.

Think my phone is dead. Won't boot. any ideas?

I've been having a few issues with my Nexus 4 on 5.1.1.
Twice in the past month I've had random Force closures of all aps. Facebook was the worst. But then it goes on to all other apps including the launcher.
First time that happened I did a factory reset and things went well. Yesterday it happened again while it was on another charger and I can get my phone to boot.
The screen backlight looks like is on when it's plugged into the charger and will go out if I hold the power button down for 5 to 10 seconds.
If I hold the power button down for 10 seconds when the charger is connected the LED flashes red till I take my finger of the Power button.
I've let it charge overnight (12 hours) and I've tried holding both volume buttons with the power button.
As well as Volume up and Volume down separately with the power button.
Is the phone dead? anyone got any ideas on how to bring it back to life
I've got a screwdriver set on order as I don't have fine enough star screwdriver to remove the internal battery connection. Which is my next step..

I think you are right to try replacing your old battery. Be careful while scraping it out where it is glued in not to tear it up too bad because it can 'splode. Might want to use a plastic card for that. I used a metal shim, an iOpener, and am much better now...

I'm going to try just unplugging the battery from the board first before I attempt to replace it.
Think it's time for an upgrade anyway.
Got my eye on the "OnePlus-X" as my next phone.

Removed the battery and stuck my multimeter into it.
It's got V output of 3.61 volts but amps drop off a cliff to zero as soon as I touch the contacts.
New battery arriving tomorrow.

i have the same problem with my nexus 4 dude. it boots when it is connected to the charger. basically it works like a desktop. I went into recovery mode and did a fectory data reset and wiped all the cache. Pliz help me proceeed. I kind have a hunch that its a software thing. did yours start working ater change of battery? Thanks ..

yes dude. i can go to recovery without it even being plugged in. I m pretty frustrated. I plan on giving it to the repair centre but he will charge me a bit high. Doesnt matter will let you guys know if I do find a solution.

Well my "new" battery arrived yesterday.
And it's getting sent back today!!
Got it through Amazon and when the battery arrived it looked ok but would not charge. I took it out to check the contacts and the ribbon came away form the battery! Looks like it was not soldered to the battery properly (if it ever was!) Just glad it didn't cause a short and kill the phone or myself.
Getting one from a different supplier tomorrow. Hopefully this one will work!

Please let me know! I've ordered a third battery just now. The first one was an aftermarket one, the second one was apparently a knock-off, this one was smaller than the original one.
The third one is hopefully a genuine LG one since the reseller is listed on LG their site.

Dam!!
Replacement battery arrived today. Looks good.
Installed it and the same thing is happening!
Screen backlight goes on. does not seem to be charging!
Now thinking the motherboard is buggered!
But I'll keep the phone on charge overnight just in case...

Damn that sucks to hear man. Hope it works tomorrow!

Now just searching freebe sites and eBay for any damaged cracked nexus4's I could scavenge from

New Battery problem :/

Hello
So i bought a new battery and replaced the old one.
I then had the flashing red led, i got it to download mode, plugged it into my pc and then the red flashing stopped and now it looks like its hardbricked :/ does anyone have a solution or have an exprience like it?
It is a nexus 4 rooted with cm 12.1 and twrp (can't remember which)

The flashing red LED probably means that the battery is completely drained.
Plug it into a 2.0 amp charger for a few hours and see what happens.

If you give it enough time to charge, and it is an aftermarket battery, especially from Ebay, there are a ton of garbage worthless batteries out there. I picked an Ebay battery, but one with good reviews here on XDA.

Can you give us a link? I was thinking about replacing my battery as well.
I did the charger port/mic/LED replacement last week and it was super-easy, so I may as well give the battery a try as well.

First thing, if you can get the real LG battery, just get it from LG. Unfortunately in the US, you have to send the phone in for repair.
So, here is the thread I went by:
http://forum.xda-developers.com/nexus-4/accessories/to-buy-original-battery-t3110029
From that thread I bought this battery and it works OK:

New battery issues: can't calibrate, only boots via bootloader, won't complete reboot

Hi all, first time poster.
My Nexus 4 has been displaying behaving wacky. I've tried searching a ton, but can't find any posts with this collection of symptoms. Here's the story, please bear with me.
Two days ago I replaced the battery, left it charging all night, next morning it still would not boot. Every time I would just get the flashing red light. The only way it would boot was if I held volume down + power for 15 seconds, at which point inserting the micro USB cable would get the bootloader up. From there I could boot to android, but it would turn off as soon as I unplugged.
Charging it wirelessly made the battery hold charge, but still it would only boot if I did the 15-seconds-then-cable trick and chose "start" from the bootloader, or help volume Up +power. Simply holding the power button makes the phone vibrate three times and then show the flashing red light.
Once in Android, it would charge via USB and wireless. Debugging, etc. was also working. But if turned off, charging via USB gives the red light, and charging wirelessly doesn't show the white charging icon. Once back in Android, the battery indicator is all over the place, from 98% to 80% to 64%, back to 80%.I've tried calibrating, running the battery down and charging to full, but no change.
Now, every time I send a reboot command, from Android, fastboot, adb, bootloader, recovery, anywhere, the phone turns off but doesn't boot. I have to boot it manually.
At this point I went back to stock, using factory image (flash-all), and even during this I had to boot manually every time the script was <waiting for device>.
After a few more wipes and roms, I settled on Chroma (stock kernel, radio).
The system is running fine, but all the issues explained above persist.
Any ideas getting the battery to read properly? And what's with it only booting via bootloader or volume up + power. How about charging while off?
Thanks in advance for your help.

Sounds like the battery is defective or something went wrong during the battery replacement.
The red light flashing when connected to a charger indicates that the battery is fully discharged.

Thanks for the reply.
The phone charges (seemingly) normally when it's on, USB or wireless. But even at full battery, if I try to charge it via USB (computer or wall), I get the flashing light and no charge. Wireless works.
What could have gone wrong during replacement to cause this? Me actually messing up the hardware, shorting something?
My only option now seems to be buying another battery and testing whether it behaves differently.

Does the old battery work at all? If it does, you could try putting back the old battery.
Where did you get the replacement? I know that new oem replacement batteries are very difficult to obtain.

The old battery was totally shot. I bought the new one off of Amazon, but yeah total crap shoot if it's any good until you install it.
I'm just trying to rule out possible firmware and software issues before I gamble on another one.
So you think a dud battery could cause all of this stuff, from charging to booting issues?

Yup, I think it's is the battery. According to many people, the batteries on Amazon are not oem.

So, I'm just going to return this one and try to get a legit OEM.
For those on the same boat as me: I contacted LG United States and they directed me to https://www.encompass.com/ for parts.
They were not able to find the battery based on phone information, so I gave them the code printed on the actual battery I removed, EAC61898601 LLL. The battery cost US$28 plus $8 shipping (not the $9 I paid on Amazon). It's currently on a 5-day back order, not terrible I suppose.
I'll update here when I've re-replaced the battery.

Hi @dreamsignals. Did you receive and install the battery? How did it go?
I'm at the point where I need a new battery too, and I'm hoping you found the real deal and the install went well.

Believe or not, the OEM I ordered the battery from back in November called me a couple of weeks back to say they finally had it in stock. Alas, it got lost on the way and never arrived. Waiting for a second shipment now. It's like a bad drawn-out joke, ha.
Anyways, it's back in stock if anybody is looking. I can't yet give feedback on whether it works. https://www.encompassparts.com/item/10742494/LG/EAC61898601/Rechargeable_Battery,lithium_P

We'll all be retirement age by the time these batteries arrive ; )

Maybe pin 2 battery connector broken. What is the battery temperature in ampere app ? When pin 2 broken not showing correct percentage and battery temperature. If can't read battery temperature or percentage correctly, phone can only boot via bootloader. Posibble you broken battery connector jack motherboard phone when disconnecting old battery. Or it's problem only new battery (inside battery or battery connector flex cable). Try to push battery connector by finger and hold, if percentage showing ok, you are broken pin 2 on motherboard phone and must been repair by professional. Watch this video

Didn't knew that Nexus detects where is an original battery or not. I guess it's not. Damn....

I wonder if these batteries are re manufactured or pulled from recycled phones.

Battery or phone died

Hello,
New year I started with big tragedy. :crying: :crying: :crying: When I was on my PC, I found out my N910C was really hot. I took out the battery. After a minute I tried to power on my device, but without any effects. When I plug in charger to my phone there wasn't led signal. I tested battery with multimeter and i get 3.9V (which is not bad score, i think). So, what do You guys think, there is problem with hardware ( like burnt circuit board) or i should buy new battery with hope that will work ?

If the battery is giving off a charge, then it's not the battery.
If you wanna test how bad, take out your battery and plug the phone in to your USB using a wall adaptor, give it a second then insert the battery.
If it doesn't even blink, the whole thing is fried.
If it gives a quick blink, disconnect the whole damn thing post haste.
If it turns on like that, you're gonna wanna replace the motherboard.
Reason being for the three outcomes being that
A. It doesn't blink, there's no power being circulated to the motherboard. Which is good and bad. Bad cause phone done. Good cause, hey. It won't explode.
B. If it blinks then shuts off, the current isn't regulated and that can cause a lot of dangerous issues.
C. The phone can't pull a starting charge (which is easily fixed, but requires a good bit of knowledge on the hardware to solve)
