Nexus 4 - Black Screen and Red LED - Nexus 4 Q&A, Help & Troubleshooting

Hi,
my nexus 4 stops working in just a day.
In the morning it was fully loaded and after pulling out the charging cable the smartphone shutsdown immediately.
If i try to power on the smartphone nothing happens. not even blinking red led. Even if i press power on or power on + volume down for long time.
If i connect an usb power and press press power on or power on + volume down for long time the smartphone led blinks in red.
I also measured the battery voltage. its about 4,2Volts. So nearly fully charged. Is also tried another battery which didn't help niether....
I have read many theads about this problem and i have tried many tutorials but nothing helped. I can't get the nexus 4 to get to the booting screen.
Maybe motherboard total damage?
Cheers
Christoph

How old is the battery? I suspect it could still be a battery issue.

The battery is about 2 years old.
What i have done now, i have bought a used nexus 4 with a cracked display.
Then i used my old case with display and battery and assembled it with the bought motherboard.
Problem solved now but i have no clue why the old motherboard keeps stop working...

Can't turn on my xda :(

Hi. I recently bought of ebay an almost new XDA Exec, but when I got it it doesn't want to turn on. The guy who've owned this one doesn't understand anything from hardware. I think the device has stayed without the main battery for a while (after being charged) .. let's say 2 weeks. I've plugged in the battery and charged for 1 hour already, but when I press the POWER button nothing happens. Any ideas how could I fix this? (With turn on I mean absolutly nothing happens when I press the power button)
Bloody well send it back & ask for your money back!
'nuff said?
Hi i-nZ,
Does the LED light come on to indicate that it is charging when it's plugged in?

No light. If I remove the battery while charging there is red light and if I do a soft reset there is a red light blink again. What light should I expect?
When it's plugged in with the battery, there should be an orange or green light (orange if it's charging, green if it's fully charged) in the upper left along the hinge in pda mode. No light when it's plugged in would seem to indicate that it's not charging, so it wouldn't be surprising that it didn't do anything after being plugged in, even for an hour. I haven't had a battery die on me yet, but I'm wondering if that might be the case here.
The red light that comes on after the battery is removed is throwing me as I wouldn't have expected it to do anything when the battery wasn't in. I guess that's a warning that there is no battery?
Have you contacted the seller about this yet?
Hmm. I think it is a warning that there is no battery and it is charging, so this is actually great news, cause this means the charging plug is not damaged(i think :S). I will receive my secondary battery soon. The problem with contacting the seller is that it will take ages for him to reply and such. I will surely get a refund for the dead battery if that's the issue, but I must travel in a few days, so I need that gadget working
I've got a brand new replacement battery and it doesn't work again! Again there is no green/orange/red light. Any ideas what could be possibly broken?

Sorry to say, but I think you just killed it by doing this. I believe I read it from the manual that you are not supposed to plug it in without the battery on it.
I've been actually told that the battery has been charged, so it's not a dead battery
I know this might sound stupid; but can you get it into boot mode?
The first xda exec I got had a fault where it wouldn't turn on, however if you pressed the reset button it would come on.
Of course this one went straight back to the shop. My advice is to try and return it.

When i press the POWER button nothing happens. Dunno how to get into boot mode...
Tried to do a hard reset by pressing the two buttons with horizontal line and poking the reset meanwhile, but it doesn't seem to react...
It's the power button, light button and soft reset all at once.
Also what happens if you try and charge it off of a USB connection minus the battery?
Red light, but if with battery - no light.
P.S: Did the light + power + reset. Nothing happens. There is no light blink or something (as I Had on an old pocket pc of mine).
I think it is time to return it and get a refund. Any way you just bought if right? Better do it as early as possible otherwise whoever sold you the device might not take the responsibility.
OMFG!!! The reset button was stuck... Found that myself
All fixed now?
What happened here as the fault looks exactly the same as my current issue....

blinking red light, phone seems dead

Just want to say I have done a lot of reading and testing before posting here. Disconnecting/reconnecting the battery, all possible button combinations, charging the battery externally (for good measure, it wasn't dead, tested with a multimeter).
This is my daughters phone, it simply shut off and refuses to turn on. However plugging it in makes it blink red. When plugged into the computer into a usb2 port it blinks red 7 times. When plugged into the wall it will blink red 11 times. The only plausable explanation of this I have found is this post http://forums.androidcentral.com/go...ed-light-follows-motherboard.html#post3719526 and this image which is the supposed fix https://i.imgur.com/WewiGBe.png .
Any more ideas before I call this thing officially dead? Btw well past it's warranty, so I can be pretty invasive in fixing it since it's really just a brick right now.

If you have to junk it, Expansys has a deal where you can get a remanufactured N4 8G is 129.99/ 16G is 149.99 http://www.expansys-usa.com/google-...9aU-aXzeibXDvErq.KMVvZ4neA&ito=LKSTM20TXf59aU or you can get both a 16G AND a Gen 1 N7 for 179.99 http://www.expansys-usa.com/google-...rtphone-bundle-16gb-tablet-16gb-phone-269434/
I took the N4 offer the other week, and all is well.
You could try a new battery. It could be that the cable is damaged, or something in the circuitry is damaged.
Found someone with a broken screen, going to borrow it and try his battery.

did the battery swap work? My GF's n4 has the same issue.
Battery tests at 3.72 volts, no button combos work, if I hold power and plug in usb get a solid red followed by similar blinking pattern.
She will flip if it is dead (luckily pics are auto backed up of the baby)
If a battery swap works, I will be all over a new battery.
On YouTube there is a video of the guy who had the same issue... He came up with a good solution.. Search "nexus 4 red light of death"
Sent from my Nexus 4 using XDA Free mobile app
I figured mine out last year. I don't have it anymore. But. I held power down for like 30 plus seconds. Then while the charger is in phone plug into wall. In that order. Fixed it. Seems the phone gets in a deep hibernated state.
Sent from my LGLS990 using XDA Free mobile app
thanks for the response, I have tried pulling the battery, button combos, holding the power button for up to 20 minutes, vol down plus power, vol up plus power, vol up and down plus power.
Swapping cables, usb ports, wall chargers everything that every site / forum has suggested.
The only thing I haven't done is swap the battery, and since I have the same led blink combo as OP, if a battery swapped fixed him, it is worth spending the money, otherwise I am wasting $30 bucks.
Other posts have suggested the blink combo (7 usb / 10 power) might be a pmic chip going bad so I don't want to waste money on a battery if it didn't work for OP.
A different battery changed nothing.

thanks for the update, yeah I bit the bullet and got my GF a moto G 2014. Not quite as nice as the nexus 4, but I got a good price on it.

[Q] My Nexus 4 just died. Help me!

I was playing a game (Circle) and the screen of my Nexus 4 just turned off and the led from the bottom lighted green. I can't do anything. It doesn't start. I tried volume down + power and both volume buttons + Power and neither of them do nothing. The only thing that appears is the battery charging while I connect it to PC. but my PC doesn't see the phone.
Please, help me ! Thank you.

EDIT
I solved it, eventually. Because XDA is the first place I search for a problem, I tried after posting this to find solutions somewhere else. In case someone could need this too, I'll say what I've done.
I pressed VolumeUp+Power for about 60seconds, then pressed VolumeDown+Power while connecting the charger. (Just simply connecting the charger didn't work)
Then after 5 seconds the bootloader screen appeared and pressed Power to choose Start.

Maybe the battery died? If the device is old, battery reading can be incorrect, so the device just dies when it runs out of juice,
even though it supposedly has lets say 30% of juice left.
Charge it for a while and try turning it on.

Yes, I guess the problem was that the battery drained very fast. I had about 30% when entered in the game and I had the phone connected to PC, but I think there was a connectivity problem and my PC didn't recognise the phone and this leaded the battery to not charge and drain (I didn't observ that). It was the first time in 2 years since I have the phone when it turned off because of the battery. So I didn't know what that red (not green) led flashed and the phone react like dead.

[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 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? I installed CM12, successfully, without any errors, then just restarted phone, and its dead...

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.

How to turn on wileyfox storm after battery fully drained.

Hello to all experts.
1- Accidently my wileyfox storm battery was fully drained at night and i was not at home during that time.
I connected mobile to wall outlet it was showing red colour on home button when connected (as a battery charging indication) but after near about 8 hours i tried to turn it on but no luck. I pressed power button for many seconds, many times but no luck.
Now what should I do to turn on my wileyfox storm.
2- My second question is how to open back cover of my wileyfox storm. i did not find any notch or point to open back cover to see inside.
Thanks in advance.
Plug your phone on charge but not in usb, and wait about 20mn
I am having this problem as well right now, how did you fix it?
I too have the same problem , it was off because drain , but then put in office is no longer lights . the light is always red . what can I do?
Leave it charging for a while from the mains. Red light means charging on low charge, the screen doesn't turn on until it has some charge.
it is normal to be in power for eight hours, and nothing has changed ? Red light always on and off screen

I am no expert, but I've had the same problem after fully running the phone battery down. While looking for an answer I managed resolve the issue by to hold the power down and down array while the phone in chagrining for around 2 minutes and the phone started up, almost by complete accident.

I had the same issue you are having, battery ran down to empty, charge light would always be red no matter how long it was plugged in, slow charge, fast charge, holding down the power button, even with the inclusion of the vol down, nothing worked.
I fixed it by opening up the phone and disconnecting then reconnecting the the battery. After doing so the phone started to properly charge (phone booted up and displayed the battery animation). Everything now operates as normal, though I won't be letting it drain to 0% again, that's for sure.
If you're able to, give it a shot and hopefully it will do the trick for you as well (though I'm probably way to late).
Hello to all
I again have the same problem, the battery of my storm has fully discharged, but although is it charging for many hours the LED light is always red and the phone will not turn on. This time even while holding together power button and volume less nothing is happening.
Can anyone help me and tell me how I can fix ?
Level1imp how did you open the phone to disconnect the battery ?

After I read your message here, I've tried and finally I solved this problem in my phone.
I was getting crazy because there isn't place to fix this phone in my country and the company Wileyfox wanted me to send my phone to someone in europe to them send to Wilefox to fix it. I've spoke with the company today to see what could they do for me and the solution they gave to me was this and to I try to open the back by myself. But this last solution it isn't a solution because would make me loose the garantee. Why the technician didn't told me about this solution? I'm so disappointed with them.
hi i have a wileyfox storm it is not going on when i press power button .now i connect with wall charger so it show a red circle on the bottom and phone show logo on and of .how can i put it on
This works!!
For anyone who needs it, this also works on wileyfox swift 2
Had this too, but solved
Just had this problem occur on my Wileyfox Swift 2 Plus. Completely drained, left on charge for 4h but it got 0% charged in that time.
For me, hooking it up to a slightly stronger power source (5V 2.1A) USB port of my power bank,
in combination with Power + Volume UP
Got me to a boot screen I'd never seen before.
Hit Fast Boot, it looked like it just turned off again but a few seconds later I saw the normal boot screen pop up
