[Q] Is my phone bricked or is it a simple battery issue?

Ok so yesterday I had my nexus 4 in the charger at 46 percent and i was about to send a tweet when the screen froze. thinking it was a simple crash i pressed the home button and no visual response then it powered off. now whenever i try to power it on nothing happens. i tried pressing the power and volume buttons. whenever i try to turn it on and i plug it in the red light flashes. sometimes it flashes continiously sometimes it is a solid color. so what can i do it wont communicate with the computer. im not sure what the issue is. is it a battery issue or is it impossibly bricked. i already charged it overnight to no avail.
oh and im running stock cm11 with the stock cm kernel. i just installed it the night before.
im planning on just openning it and unplugging and plugging the battery back in. will this work?

Try power button + volume down for 10 seconds and than plug in the power cable. You somehow must try to boot into bootloader.

How many times did you try that? It may don't work in the first time.
But if you can screw off you phone, that I would suggest to look after the batterie :good:

It is hard to say, because there are so many reason why your device doesn't boot only left the red LED flashing. One reason could be your batterie which is bricked. Another reason could be a thermal shutdown cause by overheat. And of course there are those little, little software issues that only appear once in five years...

[Q] N4 doesnt turn on. Red Light blinks once.

Hello.
When I try to turn on my N4, I hold power button, and after about 10 seconds Red light blinks (just once, if it's connected to USB that 1 blink last for 3 seconds, if connected to wall, it's just quick 1 blink. If it not connected anywhere there is no action at all, it just stays dead, no blinks, nothing). Same if I try to go in bootloader by holding volume down+power.
This happened after I successfully installed CM12, with no errors. Then I rebooted my phone, and it just stayed black as it is now. Battery was around 25~30% that time, and phone was connected to USB.
Did I bricked my phone totally? I am now trying to charge it up already for 1 hour... but it nothing changes.
I have searched here for similar problems, but couldn't find solution...
Edit: Charging already for 10h+ , still same..
Edit2: I removed battery, reconnected after a while, still same problem.
So I tested it with multimeter, it says 2.6V, but fully charged must be 3.8V. Could this be a problem? I was charging it for whole night.
Edit3: I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...
When I connect to PC usb, there are unrecognized deviced called "QHSUSB_DLOAD".

easy fix
Hold down the power button and the volume down button at the same time until phone reboots. If you see the little android no need to worry just let go and wait for your device to reboot on its own. This is not a factory reset it's just like restarting your device. :good:

I have tried that many times. Nothing. It's bootloader screen, but I can't get there. Nothing happens. If I keep holding volume down+power it just keep blinking once every ~10 seconds, same if I hold just power button. If phone is not connected to charger, there are no blinks at all.

I removed battery, reconnected after a while, still same problem.

I had the same problem a year ago, I tried to remove the battery, charging all night, and other solutions that I found online and no one worked.
Finally I found here in XDA a user with the same problem and his solution was charger the phone with a wireless charger, a friend of mine has one and I put the phone to charge and after a few minutes the screen goes on and the phone was charged, then I press power button and the nexus run again.
Hope this works.
Sorry for my bad English, I'm from Spain.
Good luck.
(I bought a wireless charger in case it happen again)

I don't know anyone with wireless charger. I already ordered a new battery, and then I probably will get wireless charger also. Ty.
But this problem is very weird if you think so.. I think it happened because of many aspects together:
1) Battery was already below 30%
2) I pretty regularly charge phone with USB (won't do it again)
3) It was connected to PC USB in same time.
4) I installed CM12 ROM in same time
So main reason I think is USB, that I restarted phone while it was on pretty low battery and with USB connected.. phone restarted and got invalid voltages and couldn't even boot up or charge phone. I also found an article which says, minimum voltage, when phone battery has 0%, it's 3.0V, so I was below that.. it just screwed everything and battery died. Well, I am not sure for 100% that it's battery fault, but I hope so, I really love my N4 and still wanna use it for long time, I hope it's not dead phone, just a dead battery. Lets see! I will update this thread , when I get my new battery (less than month probably).
Sorry, my english is also not perfect. I am from Latvia.

I was playing when it happened to me. The phone was very very hot and the battery was around 70%. When I put in the wireless charged and I can reboot the phone the battery was at 65%, so it had charge but the phone won't boot.
I charge my phone almost every day, sometimes with AC, others with USB (plugging to PC) or wireless that depends of my needs
I hope you can fix it. Good luck.

Btw. Do you know if battery charges with wireless charger, if it's removed from the phone?

Don't think it does, since the receiving coils for wireless charging are located just behind the glass back.

Major Issue Google
This "Nexus SOD" issue is showing up on many sites across the Internet. I have multiple "Nexus" devices including 2 Nexus 4, 1 Nexus 5, 2 "Nexus 7 2013". It suddenly started out of the blue with one of my Nexus 4 phones. Symptoms included rapid battery discharge. I am using Lollipop 5.1 on all devices. There are many claims as to the cause, Hardware Motherboard, Power Button etc. Others claim it is "Software Related" or App Related. The problem effects Nexus 4 and Nexus 5 phones. I have ordered a new motherboard for my nexus 4 device and see if that makes a difference.
This problem should warrant a "Major Android Lollipop Crisis Team" by Google to investigate the cause and let us know what it is and what Google is doing to solve the problem before moving to announce "Android M". This issue needs to brought up and actively pursued at the upcoming "Google I/O Conference" by the strong Android Developers Groups to press for "Formal Action"

I had this problem a long time ago and my fix worked for me after doing a little research it seems like this is a case called battery total discharge. The fix was simply to charge your phone using the wall adapter that came with your phone (I still use my old apple cube wall thing) and to wait for the red light to appear then wait about ten minutes before trying to reboot.

I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...

I have checked all kind of videos there. Also that one. Most of these cases are related to battery, but it seems in my case it isn't. I just searched for QHSUSB_DLOAD unrecognized device, all posts says it means phone is bricked... But cmon, how?

Did u try booting the phone without battery by connecting to wall charger and what about flashing stock ROM via PC
Also check that the power button works
This case should be solved

Just tried booting without battery, and connecting to wall. Same - red light blinks once, after I hold Power button or Power+Volume down for about 15 seconds. If I keep buttons pressed, it just repeats every ~15 seconds.
Power buttons works fine.
After I checked that Device manager thing in google.. it looks very bad.. phone is dead.. probably need to change motherboard. I am just shocked, how this could happen... I didn't receive any errors during CM12 installation. Phone just instantly died after restart.

Phone doesn't turn on

Hi all,
I'm having a bizarre problem with my OPT. The thread title doesn't really adequately explain the issue. Basically, if I shut the phone down, it will not turn back on. It won't boot to fastboot, recovery, or system. There is simply no response. If I plug the phone in, then after hours (or minutes, randomly), the battery icon will pop up with a red charging light (indicating a low battery?). However, it does this even if I shut it down with a full charge.
As an example, I shut it down before i went to bed last night (with ~80% charge), and left it plugged in. I got up this morning to no sign of life, not even a charging light. I unplugged it, plugged it into my PC, and an hour later I hear the little "new device" sound, and suddenly the red charge light is on. I wait some time, then attempt to turn on the phone. Then I hear the "device disconnected" sound, and it's dead as a brick again.
It also does this once the battery gets full. Eventually after attempting to power on the phone over and over again, it will randomly decide to turn back on, and then the phone works fine until shut down/rebooted.
Has anyone experienced this or have any advice? I'm hoping I just have something corrupted in my boot files or something software/firmware-related, but it makes the phone essentially unusable (and I certainly can't install a different ROM or anything while it's behaving like this).

Hi
Flashed Bad file ? Power problem ? Dead battery ? Charger problem and / or cable ?
But I already had that on my OnePlus 1 and I just changed the battery ... If it helps . Good luck anyway !
Be tested no choice. Unless you have the guarantee and a lot of time to waste in OnePlus...

I haven't flashed anything recently. I got the phone in September... unlocked, rooted, flashed TWRP, but haven't done anything since.
It's acting like the battery is completely dead, and it needs some time to charge before it will allow me to turn it on. But the battery is almost full.

You often dumps your O+ thoroughly ?
Because if so, it's not a laptop battery after I could be wrong but from my misadventure with OnePlus 1, it tires more battery than anything else. (On phone) :silly:
That way I'm not saying Fakir but I think if you have the guarantee, you should try to open a ticket to return your Oneplus. :good:
When my OnePlus fully discharged for a while he puts around 10 minutes to re-ignite (Oneplus 1) it is also how I ****ed my first battery on the OnePlus 1. :crying:
Not try to completely unload the O+2 from...
I'm just trying to help. :angel:
( PS : I still want to clarify that OnePlus 1 when it makes a point that the battery is empty it puts at least 10 minutes to light if I have the logo of the empty battery in red, even super you tell you my phone is dead ! And It is not ! If you know how is the process of loading a battery. And if such is your discharge too fast or you have a problem or charging your battery discharges of a sudden, I tell you it's more than problable so that your battery is lame. ) ( Sorry 4 my bad english.... )

The battery wasn't dead, I just shut the phone down. I very rarely discharge it all the way. Battery life is fine when the phone works. It's almost like the charging circuit THINKS the battery is dead and won't let it turn on. I'm not sure if this is a hardware or software issue.
Actually I just turned the phone back on. I just kept pressing and holding power until it finally responded and turned on. But now I'm afraid to reboot it again, or i'll be without a phone for 6+ hours.

Did you try to do a full wipe and install stock OxygenOS 2.1.2 ? ( Without SU or XPOSED ?)
Good luck anyway ! For me it is 0:23 am in France and I'm k.o :silly:

[HELP]Phone Dead

Last night I left my phone charging overnight.Today morning when I woke up phone was working.I opened snapchat and phone got stuck.I gave it some time but the screen turned off after a while and now the phone is dead.No charging animations,no recovery mode,no flashing LEDs,NOTHING !! I have bought phone from 3rd party seller(Flipkart - Google's official sales partner here) coz Google rarely had the phone in stock. Also my 1 year warranty is also over.

Do you mean it won't power on at all? If so, hold the power button only down for 2-3 minutes or until it boots, or not.
If you meant it starts but gets stuck at the Google (no startup animation) and you cannot access recovery mode, that is totally different.
Connect it to a PC and see how it is detected in Device Manager.

I tried holding power button for several minutes. Nothing .
It does not show any signs of life, and its definitely not stuck in a bootloop.
Also got nothing in device manager too , not even EDL 9008 Mode.

Seems like after charging all night, the battery would be full. Never heard of a 6P dying on the spot with a full battery. Were you using a stock charger or aftermarket? Wall charger or something else? I'd put it on a *different* wall charger overnight and try the long power button press again. At least 2 minutes.

Stock charger. The charger works fine as i have checked it with other phones.

Either your charging port is bad in the phone has no juice and died. Or the battery is bad and come morning it died because of the charging all night. Or possibly the power button connection is bad internally maybe broken and can't turn on. I had a bad power button

How did you know it was a bad power button?
I have a similar problem as the OP. If I shut my phone off I can't usually get it started for about a day or 2. I'm starting to think I may have a bad power button as well.
*Edit*
It can't be a bad power button on my unit cause it works flawlessly with the phone on. I'm stumped.

I guess the battery has been dead coz I have faced similar situation with my HTC ONE X+ using it for just a year and the battery got swollen and it's completely dead. I went out to a repair shop nearby and after opening the mobile, the battery was completely swollen and the technician just replaced a new battery and it did boot up and worked fine. So from my experience I guess it's the battery that got damaged completely (dead) and you need to replace the battery. Hope this information is helpful

You couldn't tell the battery was swollen before the phone was opened up? I wasn't aware until recently that this was a potential problem with the 6P but since other people have reported the same I guess it can be added to the list.

My job involves troubleshooting electronics with circuit boards all the way up to 3 phase hv. It's probably likely a power issue which is either the battery, screen, board, switch, or connection. But the most likely are the forementioned.

Thanks v12xke! Holding the power button worked like a charm! I still don't know why it blacked out on me but it is working now.

S7 Edge isn't turning on

Hello.
So, I recently updated my phone 2 days ago for the first time after 2017, and the battery ran out while it was updating, and then it was boot looping and kept getting stuck at 28%.
I decided to reinstall the os on it (I installed the official rom that the phone came with). At first, everything seemed normal until I plugged it and after a while, the led indicator was showing that it was still charging but after I unplugged it from the charger, the light was still on and the screen was completely black and unresponsive.
After a while, the light shut off and after that, it never came on. I tried everything to get it on again: tried hard rebooting, trying to get into recovery, charging with different types of cables and with wireless charging also, basically every combination that came to mind. When I used the wireless charger, it showed that it was charging, but no signs of life on the phone. Samsung support wasn't that much of a help either, they only asked if I used a cable that worked on it and if the phone was water damaged or had any cracks.
Any help will be appreciated!!!

How did you reinstall the OS?

by putting the phone into download mode

Connect usb (not charger) hold vol- + home + power, release power after 5 sec n continue holding vol- + home . If download mode appears flash phone with same csc firmware. If no downlooad mode probably battery or emmc fault.
