Think my phone is dead. Won't boot. any ideas? - Nexus 4 Q&A, Help & Troubleshooting

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

Yes my phone shut down on its own. Rebooted it launched car mode right away I went and shut it off and then BLANK.
And now if i can even get it to power on it does for less thn a second before going dark.
I tried both my extended and stock battery. Phone be dead.
Next question can I take it into a sprint store and have it replaced under a defect or am i shelling out cash?

With the battery inserted and the phone off, plug it into the wall outlet. Does the orange/green light turn on?
Try unplugging the charger and remove the battery. Then press and hold the power button (to flush any left over charge).
Insert the battery and power it up. Let us know the results.
Also, did you do anything to your phone? (i.e. SetCPU? Flash a .zip file)
Good luck dude.
I have done all of that.
ALSO NO LIGHT COMES ON WHEN PLUGGED IN with any of my batteries. (STOCK and a 3500mAh battery)
I have put on set cpu using the profile ONDEMAND
I did not flash anything. It was on sitting there next to me and it just shut off. I was not doing anything at the time. When I turned it back on it was in car mode like it sensed the dock. I was like okay well bugs happen. So i swipe down turn it off. And then the car mode indicator stayed on and i was thinking well wtf. Then my screen went black. I then pushed the power button and i swiped to enter into the home screen which was black then a few seconds latter it gave me the loading screen like it was loading sense then *DEAD* ...

Sounds like the phone is pretty much toast then. There shouldn't be any harm in taking the phone in and seeing if a warranty exchange will be done. At worst they'll tell you that you gotta pay up, and at best they'll either be able to fix it or offer a replacement free of charge.
If you gotta pay up then you do always have the choice of refusing, in which case you're left in exactly the same situation you are now; a broken phone and no money out of your pocket. I say take it in, see what happens. No guarantees either way but surely it's gotta be worth a shot.
I got a sprint store that does not do repairs but its a corporate sized store.
Then inn victorville I have a store that is a 3rd party store but offers all services except 4g... They are on the same road. So tomorrow I am hitting the sprint one first to see what the deal is.
Anyways I think i might get warranty due to it just failing all of a sudden.
Also do i have to give them my memory card back?

Sweet. It sucks alot due to it failing and my class schedual for college was on my phone >.<

You never give the SD card back. It's been a while since I've gotten a replacement phone, but I'm fairly sure you get to keep the charger cable and a/c adapter as well.
That is how it should work.
Have them boost your battery on their cadex machine anyway.
I've seen people come in with supposedly fried phones that wouldn't light up for anything. Quick cadex boost and they're out the door with a working phone again.

Hopefully you didn't have your phone overclocked and caused it to go haywire. What kind of Kernel did you use? Was it SBC or non-SBC?
Well my EVO came back alive... Idk why but it just did.. I don't understand why it would re act like this.
But I do not over clock. I use on demand and smart ass for battery. I dont over clock but i under clock to 128 for min. I use the freedom aggressive v8 . I have not had a problem with undervolting ever before..

check the pins on your usb connector for items than can short (foil gum wrappers etc). That could have been what kicked it into car mode too.
Glad that it came back dude

I am not sure. i switched to the newer 8.5 kernel and started using my stock battery. So I am not sure what fixed it but it eventually came back to life...

Battery status stuck at 0%

Recently I purchased my first tablet, ofcourse the Nexus 7 32 GB and I am very happy with it.
As soon as I started it, I received the notice that an update was ready to be installed, which I did (4.2).
After that I got another notice to install 4.2.1.
So far so good, everything worked very well....also the normal charging with stock charger and cable.
Then after about 1.5 weeks I noticed that my battery level didn't went down from 100% to xx%, even after playing games for several hours.
I am absolutely sure this wasn't the case before, I did charge well and battery-level went down normally.
So because I couldn't tell if the battery was empty or not (because it kept being on 100%), the Nexus went down ofcourse.
Well, I plugged in the stock charger and cable and started to charge it.
Battery icon (when Nexus is off) nicely went from first quarter (25%) to full (100%) when I unplugged it.
It booted up nicely, but then I noticed that the battery-level showed 0% and kept stating 0%. Even again after playing games for several hours (GTA4 and RR2).
Normally it should decrease in battery-level ofcourse.
So now I'm stuck at battery-level 0%, but strange thing is that the Nexus works fine besides this small problem.
I can charge it, play with it for several hours, reboot, deplete the battery, etc....
Only thing is I can't see the actual battery-level which is very annoying, since I never know when the battery is empty and needs to be recharged.
I searched internet using Google and also here on XDA, but never found a solution.
What I already did was :
1. Reflash stock ROM, using the Nexus Root Toolkit.
2. Flash CM 10.1 with CWM Touch
3. Tried to hold down POWER + VOL UP + VOL DOWN for 30 seconds
4. Tried POWER + VOL UP
Nothing I did worked.
Did someone had this problem before and was able to solve it ?

Hi,
I had this issue too when i purchased my nexus 7.
For solve the probleme I've remove the back of the tablette then unplug and replug the battery.
Don't had any other issue. its realy a nice tablette you have make a good choice.
Sounds like a problem with the fuel gauge chip... Not sure if you can fix it.

That file only stores the data used to fill the battery graph... It has nothing to do with the actual calculation of battery percentage.

Check out this thread, there's people talking of a fix for PA for battery percentage stuck at 100%.. Maybe the same cause as your problem... Look from post #10047 onwards.. Makes me think its probably not a hardware issue at least.

In PA, is definitely a software issue and seems to be caused by paprefs. The issue that is commonly reported with the N7 across all roms is typically caused by the battery connector not being properly seated. Asus QC consistently has fallen short on this connector.
Sent from my Nexus 7 using Tapatalk HD
I have fixed multiple loose battery connectors using clear scotch tape. The problem is that they didnt use any adhesive on the battery for a batch of n7`s. Makes it possible for the battery to slide back and forth at least 5mm. When it does it pulls the internal battery lead right off the mother board connector. Tape the connector tight. Then tape the battery to that side. Do NOT tape over the copper tape. I even made a small strip of foam to place along the far side of the battery to remove the room to slide.
Easy fix for an annoying problem.

I can surely try to open the back and check if the battery cable is seated correctly, but I'm wondering....
If it isn't seated correctly, wouldn't that mean that the battery isn't charged at all ?
In my case the battery is being charged and depleted normally, since I can use the N7 to play games etc.
Only the battery-level indicator keeps telling me the level is at 0% and it says "unknown".
It's just annoying as I don't know when it's fully charged or fully drained.
Now I let it charge for a complete night and work with the tablet untill it dies on me.
Just to let everyone know, who might face the same problem :
I pulled off the back cover and found out that indeed the connector, coming from the battery going to the mainboard, was not fixed in its socket.
It was not completely out of the socket, just not firmly pressed.
So I pressed it firmly and put back the cover.
After restart, the readings are back to normal.
Thanks everyone for pointing me in the right direction.

I have exactly the same problem!! Can you please help me. I tried what you said - removed back cover, pressed the connector hard, and switched on again. The problem is still there. Can you look at this picture - http://android.hdblog.it/wp-content/uploads/2012/07/Nexus-7-Teardown.jpg and tell me if the connector are the red and yellow wires on the left, on the side of the tablet closest to the camera? If so, how did you press it? Could you explain those steps once again please?? Much appreciated!

Make sure you put a piece of tape on the connector to secure both pieces together and also one on the battery to prevent it from shifting. The newer n7's had a battery that didn't fill the space for it...allowing it to shift and pull the connector free.

I had exactly the same issue. Word 4 word.
I took the back off my n7 (take the SIM holder off 1st, makes getting the back off much easier) and noticed the battery connection was loose. Unplugged fully, replugged and got my battery % back! :thumbup:

First off, for everyone that has battery-related problems, please check my thread:
http://forum.xda-developers.com/showthread.php?t=2090826
It provides "fixes" to a number of battery-related issues.
Second, the cover is really easy to get off. Just use your fingernails. Start half-way down one of the long sides (I forget which, but try both - your fingernails will easily slide into the seam). Gently snap off the cover from your starting point. Slowly work your way around. If you go slowly/carefully, it'll come off rather easily and without breaking off any tabs. It snaps back on easily as well.
In my post, I recommend that you apply a small piece of electrical tape on the battery connector, as they have shown over time to come loose for a number of N7 owners.
In all but the occasional rare case, N7's with battery-related issues are easily "fixed" and do not need to be returned for replacement. Just read my thread. It'll save you a lot of time and frustration. It'll also might save you from a needless return!
Good luck and report back.

Strange. my tablet is doing the weird battery bug. Battery stuck @ 100% for quite some time, even after a whole day of idle and @ home usage after work.
Realized it wasn't dropping.
This morning, I opened up the back and checked out the battery. It was glued down so not shifting around, but I noticed there were fingerprints on the copper material. Odd thing is I bought this tablet new. Box was sealed and everything.
So far I unplugged the battery and plugged back in. Haven't turned the device back on just yet. Might wait a couple hours and see.

Yup I stumbled upon your thread after a bit of searching. The tablet was actually rather new, just purchased a week ago. Was charging and draining fine for few days of ownership, and all of a sudden it started acting up. I realized it was too good to be true seeing 100% battery % after a whole day + gaming on it @ home.

Nexus 7 Won't Turn On

Hey everyone,
I've tried searching, but no luck, so here's my issue.
My nexus 7 was around 25% battery last night so I plugged it in for the night.
Woke up this morning and the backlight was on, but the screen was off.
When I unplugged my n7 the backlight turned off. Hitting the power button had no effect.
I then tried pushing and holding the power button for roughly a minute, nothing.
I have disconnected the battery and still no response from the unit.
I plugged it back in for roughly a minute as well, still nothing.
Unfortunately I don't have access to a charger right now.
Is it possible the battery is dead even though it was on the charger all night?
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2
Weird.
Just plugged it in to my car charger and it booted up. Battery is completely dead, so I guess with the backlight staying on all night it didn't charge.
Now why would the backlight stay on if the screen is off...

Don't go flashing different roms and kernels now like most of the idiots here, it could just have been your charger being faulty or a bad connection to the tablet overnight. if the problem happens again then you can investigate further.
BTW, were you charging from your PC/Laptop with a USB cable or through a wall adapter? i've had issues in the past charging my Nexus 4 and 7 not charging overnight on my PC
I feel like a broken record but since I've fixed a ton of n7s with loose battery connections, I would recommend checking the internal battery lead to make sure its not loose. Asus didn't do a good job of making sure all n7 batteries were secure and this allowed the battery to shift and pull the power lead out. Some clear scotch tape on the connector and one on the battery (avoid the copper tape areas) will eliminate this problem if that's what you have.

I ran into this problem. Initially, my Nexus 7 didn't start. When I plug in the charger the screen would flicker from time to time but there's no indication of charging. So I decided to open it up to see that the battery cable has loosened. So I managed to fix it and use it happily thinking that it won't happen again.
Since last week, the same issue happened. I thought it was the same issue and opened it up to see that the battery cable is firmly in place. So I got a shock. I removed it and re-inserted it again to see if it fixed it. But nope, it won't turn on. And now it's been a week and I don't know what to do It's nothing wrong with the loose cable cuz now it's firmly in place.
Now when I plug it in to charge, the screen will just flicker (as in the back light will turn on and off in 5 sec intervals). What do you think I should do? I tried holding the power button for 30 secs as well.
I bought this new from eBay and still under warranty. But I live in Sri Lanka. So when I bought it, I had to ship to a friend in the US and had to wait till he came down. So it's not easy for me to ship back and to receive another device. Hopefully I can find a solution to fix this myself.

Make sure that the cables between the battery and the connector are intact and not broken. One or two people reported a broken cable.
Does it boot while plugged in to the charger with the battery disconnected ? You could simply have a bad battery.

It doesn't boot when I plug in. Actually it doesn't show anything on the screen. If I look closely I can see static flicker on the screen from time to time. Just like the static in TV but much much less. Like only a few of those in certain places.
When this happened the first time I opened it up to see the loose cable. So fixing that helped it then. But now I dunno what's causing it.

Might have to try a different charger, maybe something stronger. I JUST had that problem with my GF Nexus 7. It wouldn't boot with her normal charger and the screen would flicker like a TV. I used my Nexus 4 charger and it worked.
She had left the battery fully drain for over two weeks and I think the battery didn't appreciate it.

(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.

If you take your time there is no way anyone can tell you've taken the back off.

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.

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.

Sounds good. Finding and obtaining a legit battery for this phone is a bit of a monumental feat. Seems like installing it is the easy part in comparison

It seems you were totally right. I've got nowhere closer to getting a new battery that actually works. All dead-ends so far...

Much appreciated for the update. I haven't found a place to buy a battery yet either that I feel would be the real deal. Will report here if I do.

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

having the same problem with a battery I just got replaced. Wish I read here before installing a new one
Didn't knew that Nexus detects where is an original battery or not. I guess it's not. Damn....

Sorry to revive an old thread,
Did you ever recieve the battery? How is it? What's the date code on it?
I wonder if these batteries are re manufactured or pulled from recycled phones.
