Tanks but it does nothing.

Some times I can see google logo for about 2 sec then it turns off and red lights starts blinking, but normally it turns off directly.

PD: Last night was charging for about 12hrs and this morning it was charging.
[Nexus 4 General] mymeatb18:
That's weird bro last night I passed out and didn't charge my phone woke up then put it to charge with blinking light then a few seconds later showed battery icon and turned on fine later.

Maybe your phone is just done

How long ago did you buy the phone
[Nexus 4 General] contapapo:
Thanks mate. But I think that the battery that I bought is broken. There's something loose inside it.

Because, when I put the original one, I can turn it on while charging, but It turns off a few minutes later without charging.

Asked a new battery, lets see if I have more luck with this one, I'll have to wait another week without phone :(
[Nexus 4 General] contapapo:
Im not sure, maybe I'm wrong but I think that this points must be soldered. They aren't and this board is loosen.

Don't you think?
[Nexus 4 General] mymeatb18:
Could be the battery is bad has happened to me before when buying a battery. Not sure about the pic though
[Nexus 4 General] contapapo:
Already talked with the seller. He will send me a new one tomorrow.

I'll post when it arrives

Slight water damage

Hello everyone,

New to the forum so...

I fell into knee height water with my phone in my pocket. Was under for barely 5 seconds and I also had my hardcase on (if that helped any). My battery, if i remember, was already on about 9% when it happened. I immediately took the case off and dried as much as possible in the situation and couldnt do much else since i was camping out somewhere. I turned it off and later when I thought it had dried out enough tried turning it back on. Big mistake I know but I panicked. It passed the Google loading sign and ended up and the Android loading sign (running AOSP 4.4 Nexus 5 rom). Then it stuck there for lord knows how long since I just left it in my tent. Battery mustve died idk

By the time I got home my phone was completely dead and I put it in a bowl of rice for around 12hrs and then tried plugging it in. I figured it had barely any water damage. I tried many different button combos. When I plug in my charger now, it only blinks once and cuts off. I left it overnight charging and the led does the same thing when I plug it back in; blinks once.

Later today I'm going to try the way of the OP and see what results it yields. If not I may buy a replacement battery but it wont make sense if its the mainboard that fried. I have no way of knowing for sure.

Any advice? :(

UPDATE: By holding volume up and down while holding the power button, wait for light to flash once again, then release the volume buttons and keep pressing the power button brings it back to the flashing red LED. I'm going to leave it plugged in for a couple hours and see what happens. If not, I'll open it up and do a battery pull
[Nexus 4 General] mymeatb18:
Doesn't sound like a battery issue
[Nexus 4 General] Aeon619:
I have gotten flashing led and solid led at different times while trying different button combos.

No idea what to make of my situation still. Waiting on the screwdriver to open it up
[Nexus 4 General] mymeatb18:
I believe a constant flashing means it's still got some juice and we'll turn on happens to me if I let the phone die and don't charge for a few hours. Solid I believe means it's dead and has no charge at all and will require a long charge of 10+ hours.

This is what I have experienced
[Nexus 4 General] ramd4n:
Nevermind
[Nexus 4 General] contapapo:
No lucky here. Changed battery and it was charging for 3 hours, then I pressed power button, I saw the "X" and got stucked. Took out the charger and "puf", turned off and now I have the red light.

I don't know what to think. I'll sell it and get a chinese one.

LG never more, US$400 for nothing
[Nexus 4 General] mymeatb18:
Charge for 10+ hours. Don't charge for any less. I know it's hard but just try it
[Nexus 4 General] contapapo:
With the red light? or must do something before? Like this:

1. Unplug phone from charger

2. Press and hold the volume UP button plus power button for 60 seconds.

3. Release buttons.

4. Plug into charger

5. Wait about an hour for it to charge.

Thanks mate
[Nexus 4 General] mymeatb18:
[MENTION=5146886]contapapo[/MENTION]

Just plug it in and let it charge don't touch it.

I have called Google once to help me with this problem they told me to press all kinds of buttons. The last thing they told me to try is leave it charging for 10+ hours without touching it when I checked the phone was fully charged.

Charging while the phone is off charges slower, almost like a deep cycle charge which is better for long life of the battery.

I have had several blinking red lights after this happened to me but caught them within hours of phone dying and charges no problem.
[Nexus 4 General] contapapo:
Thanks. I`ll do that. Will be strong and won`t touch it. Haha See you guys tomorrow
[Nexus 4 General] contapapo:
well, it has been 16hrs charging. Red light has gone but i am afraid. I`ll wait 24hrs.
[Nexus 4 General] mymeatb18:
Well if u press the power button once like when you turn on the screen doors it display the charging icon? [MENTION=5146886]contapapo[/MENTION]
[Nexus 4 General] contapapo:
no. Nothing. I was thinking. I lost the charger, but now i use the original one, that`s american with an adapter. What do you think?
[Nexus 4 General] mymeatb18:
What do you have 220-240v?

With the american plugged into an adapter to the wall?

Don't think it will matter but if u can get to power on while plugged in or whatever try and get into recovery. Maybe u have no ROM or the partition became corrupted some how. I think the phone can charge in recovery
[Nexus 4 General] Aeon619:
Ok so progress report.

The water damage indicator closest to the earpiece is pink and the one close to the battery is still white. So there's a chance the water never touched the battery and it's just the mainboard that's shorting out. One battery screw isnt moving so I had to bend the contact tab off a bit to disconnect the battery. Let it sit for 5 mins then tried powering on. Nothing.

Tried powering on without the battery. Nothing.

Tried to free the board from the screws and it seems the screws are sealed with dark magic so can't go any further than the back cover area.:(

Trying a lengthy 10hr+ charge as suggested now and if that doesn't work I'll try some isopropyl

So question is.... Can I dunk the whole thing in Isopropyl alcohol for about 15 minutes? Battery included since its not budging.

I have no idea how it would react with the battery so I'm asking first.

I'm about ready to chalk it up as a loss and jump up to the N5

Thanks for any suggestions! :cowboy:
[Nexus 4 General] mymeatb18:
Do u have any red lights still
[Nexus 4 General] contapapo:
hi there mate. Thanks again for helping. We have 220v here. Pressed power 20 sec. then red light blinked twice and it started charging. Let`s wait till tomorrow. Cheers

PD. could enter in recovery, installed 4.3 again. Let's see tomorrow
[Nexus 4 General] mymeatb18:
Nice seems like it might work
[Nexus 4 General] Aeon619:
Its currently sitting on the charger since last I posted. Same blinking red light
[Nexus 4 General] mymeatb18:
I think blinking light is a better sign though just let it keep charging and see what happens. As far as dunking ur phone I would be more worried about the screen but I'm not really sure about that. Water damage is some serious stuff. Worst comes to worst bro they got the GPE moto g pretty cheap. I also saw something about the motox being discounted $100 for like one hour and $75 after that.
[Nexus 4 General] Aeon619:
I'm declaring it dead lol thanks for helping out though. :highfive: I brought my Nexus S back from some serious bricking/physical damage so I had hope

Yea Moto has a nice sale coming up and the Moto G and Moto X are pretty decent. It's between those, the N5 or something in the Xperia Z range because water resistance :)

Thanks again
[Nexus 4 General] mymeatb18:
Haha yeah my wife has the z its pretty nice phone and battery last long
[Nexus 4 General] contapapo:
I give up. I`m sure that the problem is the battery. With the old, it pretends it`s charging nd i can enter recovery, with the new one, nothing,no red light, no charging. Iĺl take it to repair, it will cost me more than 60€. But i`m sure they can fix it
[Nexus 4 General] mymeatb18:
Damn that sucks bro but when u were able to enter recovery were u able to flash anything? What about fastboot?
[Nexus 4 General] contapapo:
Yes buddy, that really sucks. It's the first time I can't repair a phone :mad:

I can enter recovery when I use the original battery, but it must be connect to the laptop. Then I can flash what I want with fastboot.

I'm sure it's the battery because I have three and with each one I see different "things". The original one charges 5 minutes then it's full, but when I disconnect, it's dead. With the second one, nothing. No charging, no red light. With the thrid one, only the red light.

That's way I'll take it to repair tomorrow morning because I won't buy another battery.
[Nexus 4 General] mymeatb18:
Yeah man sometimes its just better to get the original battery. Well it seems like u might have a chance of fixing it as long as its just the battery. Good luck I know its frustrating.
[Nexus 4 General] contapapo:
Thanks bro.

I hope so. I'll tell you what happens. See you

RLOD Driving me Crazy

Hello friends

A few days ago i ordered a brand new Nexus 4 trough amazon, after a day of normal using, nothing extreme just surfing the web and normal stuff, the screen went completly blank, i had to push the power button in order to shut it down, but once i did that the phone never power up again. I went like crazy when i saw this because im from Venezuela and using the google warranty from here its just a dream.

Plugged into the AC Charger and only shows a 1 - blink red light, and nothing more. Ive tried every solution Ive Seen around, like pushing volume up, down buttons and power, for 60 seconds, nothing. Tried plugging it at USB Port, it keeps showing the led for like 2 or 3 seconds and thats it. Tried charging it for 8 - 12 - 24 - 48 hour without luck

Ive read through the entire thread and i havent found a similar situation, I dont know if anyone here has experienced something like this, and suscesfully bring the phone back to life.

Sorry for my english
[Nexus 4 General] mymeatb18:
Try charging the battery externally like in the OP. You don't have to take the battery out of the phone to do it.
[Nexus 4 General] carmonantonio:
:(

Updating, plugged out the battery and reconnecting and nothing happened, waited 10, 15, 60 min before plugged it back and still nothing changed.

What ive noticed is that the red light keep flashing when i plug the charger wether the battery is connected or not...

Im looking for an old charger to try the complete procedure but im not very skilled with electronic parts :(
[Nexus 4 General] manpildo:
I guess I'm lucky. One day I woke up and the phone wasn't working, didn't react to buttons nor did anything happen when plugging in with USB cable. So I put it to charge with AC, it blinked the RLOD for a few times and then booted up. I was so relieved I didn't have to start screwing it open and practicing my non-existent electronic skills :)
[Nexus 4 General] mymeatb18:
Its pretty easy just try and find a charger that outputs something close to the output of the original. Usually the positive side will have some words or markings engraved on the insulation of the wire.

I used a charger that outputs 6v and I charged the battery about 15 mins and it said I had 57% when turning on the phone and had pretty crappy battery life for a couple of days till I charged the phone from almost dead to full with the phone off. That's a very important step to make sure ur battery is calibrated.
[Nexus 4 General] carmonantonio:
Ok, im gonna try tonight over a friends who has a power supply. All the behavior that ive been describing here is normal for this situation? think that i can have some sort of hope to make this phone back to life?

tyvm for the assistance
[Nexus 4 General] mymeatb18:
Yeah might have a chance. Doesn't hurt to try. As long as the battery is good it should be able to take charge.
[Nexus 4 General] nitin.chobhe:
Have you tried connecting it to your PC/laptop? Some people silver it by that way...
[Nexus 4 General] carmonantonio:
Yep I tried that as well, the only difference is that the red light stays on a little bit longer. And the PC searches for a QHUSB_DLOAD Driver, I dont really know what does it mean...
[Nexus 4 General] DJBhardwaj:
I had this today morning, while the phone was left at charge overnight. Up in morning, I had nothing but this red light. A few times it showed up to the MultiROM screen and would power off again. Tried boot to bootloader or recovery mode, but didn't seem to work.

Finally, tried plugging it to the PC, a red light flashed for a while and the then the charging animation appeared. While it was charging, I read the 23 pages of this thread in complete fear :D

The battery animation just went on, now I tried pushing the Volume Down and Power button and voila! It booted into bootloader mode in the very first attempt, from where I headed over to the Recovery mode, clearing Dalvik and Cache for no reason and booted! It just booted fine with a 3% charge.

Gratitude to everyone here who posted several solutions :)
[Nexus 4 General] carmonantonio:
Updating Again

I went over my friends to pick up my Nexus 4, and he says that the battery is completly damaged, so i ordered a new one

:crying::crying::crying::crying:
[Nexus 4 General] sinndissension:
The picture that shows the charger connected to the battery on step 7, what is that white thing the wires are connected to, that is on the charger?
[Nexus 4 General] mymeatb18:
Its tape to hold the wires in place. He did it without butchering up the charger
[Nexus 4 General] chrisyouu:
How do I know if my charger is broken?

(I use the charger that came with the phone.)
[Nexus 4 General] AP0ll0UK:
My nexus 4 started with this issue last night. The lock screen reported that the battery was charedg to 99%. Without warning the phone rebooted. It booted back up fine and worked ok for a while, but during the course of an hour it rebooted several times. The last time it powered down the screen simply dissolved in a series of horizontal lines and it now refuses to power back on.

I have tride the various button combinations with it connected to the mains and to my laptop - none have been successful and all result in the flashing red dot.

I've removed the back of the phone and disconnecting and reconnecting the battery produces the same results. I have checked the voltage across the battery which is a steady 3.97v.

Does anyone have any ideas as to what I can try next please? With the voltage being normal across the battery, I don't see any benefit in trying to charge it directly via a different charger.

Any advice would be appreciated.
[Nexus 4 General] uEih:
Last night my phone was low and was charging, as soon as i went to go check my text it rebooted and shut down during the boot screen. Now I can't start it up at all. I left it on the charger for hours and still nothing. Every time I try to turn it on i get a red blinking light.
[Nexus 4 General] mymeatb18:
Try charging for 10+ hours
[Nexus 4 General] sinndissension:
Will this only work if it's an issue with the battery, or will it work if you hard bricked your nexus 4?
[Nexus 4 General] mymeatb18:
Usually battery issue but what do u mean by hard bricked?
[Nexus 4 General] uEih:
Left it on for 12+ hours and tried turning it on, still nothing. I might have to do this battery trick, I have an old charger I could plug into the wall with a positive and negative, where is it being connected on the battery flex cable exactly? I can't secure it on anything to charge it. I want to at least know it's a battery problem and order a new battery.

It seems a little different than how others had explained it also.. My red light doesn't come on with I plug it in, instead it blinks when I hold volume down + power for a while but only when it's plugged in. Other people I've seen online has a solid red light when plugged in.

Also I tried disconnecting the flex cable from the battery and plugging the charger in and it'll give me a blinking red light every 10 seconds or so but when the flex cable is connected I don't get any light blinking until I try to turn it on. Not sure what that means but it has to mean something.
[Nexus 4 General] mymeatb18:
The first pics show which is positive and which is negative. The wires need to be pretty small to clip into the battery cable. Basically take half of the wire from the charger to get it to stay in the clip. Also, to put it in a way so it stays.
[Nexus 4 General] nitin.chobhe:
Everyone who is facing this problem, I would advise to first try and connect it to Laptop/ PC. This has solved my problem (I had got it once in Aug 2013). That's the first and foremost thing to do.

Switch it off and connect to Laptop/ PC. It should show battery charging animation. Wait for 15-20 minutes and then power it on. It should get ON, connect to wall charger and let it get charged fully. Hope this helps!
[Nexus 4 General] uEih:
Not sure if I connected it correctly but I did see a little spark when connecting the positive (outlet wasn't plugged in). I did the best I could to get it in the slot, it went in and I left it there for 13-15 minutes but it didn't work. Did it twice, it could just be it's not as secured as I think it is.

Ugh, I don't know what to do.. Gonna try the QI charger tomorrow and then if that doesn't work also maybe order a battery. If that doesn't work I think i'm out of luck.
[Nexus 4 General] mymeatb18:
The qi is the same thing as plugging into the wall. U have to make sure u know which one is positive and negative on the charger. Also if u order a new battery the best thing to do would be to order an OEM battery so u know its good. A lot of the after market batteries are defective especially the cheaper ones
[Nexus 4 General] sinndissension:
Hard bricked as in completely dead. I had flashed a bad .zip file to it, and it just never turned back on. I still get the red light though, so I was curious if this would help.
[Nexus 4 General] uEih:
I know red is positive so I got it hooked up correctly. The thing with QI charger is it will test if the USB port is fried, if I can at least charge with the QI charger and start it then most likely it means the port is dead. Also with the battery, I found the ones on ebay with LG branding on it for around $20, as long as it has the LG branding it should be fine right?

I don't even want to buy a new battery because that might not work either but that'll be my last resort, I was hoping I could revive it with this method but I must not have a secure enough connection on the battery or something.

Just tried the QI charger, doesn't seem to feed the phone power at all. Would you conclude it's a battery issue if I only get the red light while the phone is plugged in and when I try to turn it on? I don't get any lights if I just plug it in. If I try to turn it on without it plugged in I don't get any red lights either. The only time I get any feedback is when it's plugged in and I'm trying to turn it on.
[Nexus 4 General] AP0ll0UK:
I left mine charging overnight and now when I hold Volume Down + Power, just Power or any button combination I just get a solid red light. I'm guessing that means the battery is fully charged but the phone still refuses to boot.
[Nexus 4 General] uEih:
Are you just saying that or do you know that's what it means?
[Nexus 4 General] AP0ll0UK:
I'm just guessing - I wish I knew what it meant.

If the red led was flashing when it was plugged in to start with then I could accept that despite reporting it was charged to 99%, the battery was flat.

Following am overnight charge, it stands to reason that because the red led no longer flashes but in fact stays on solid, there is a further issue despite the battery now being charged.

The only problem is, one seems to know what this means other than the phone is dead. There doesn't seem to be any way to get any error code out of the phone. And I'm no good at reading circuit diagrams so I can't test the individual micro components on the board to see what works and what doesn't, or what has the wrong set of volts across it.

If there was a way to get some kind of error code out of then I'd try and get it a step further but not much seems to be known about the red led and what it actually means.
[Nexus 4 General] uEih:
I'm not sure either but I know there seems to be a pattern with them, we just don't know the meaning. I noticed if I disconnect the battery, plug it in and try to turn it on it'll blink red every 9 seconds or so. If I connect the battery and plug it in, I don't get any red light at all... It's only when I press volume down + power or try to turn it on that it'll give me a blinking red light... Sometimes solid.

I only get activity like that when plugged in, what that makes me think in my personal experience is that the battery is dead since it's not giving me anything at all without being plugged in. Idk.. I'm kinda bs it also and that's my last resort.. I hope that's the issue because I don't wanna purchase a new phone.
[Nexus 4 General] AP0ll0UK:
I seem to be getting similar results to you.

Have you tried connecting the charger to the phone with the battery disconnected?

Also, have you tried with the phone connected to your laptop?

When my phone is connected to my laptop, the red led behaves differently. It flashes whereas when it's connected to the mains it's on solid.

When I hold in various buttons, all make the red led flash, and my laptop tries to detect what is connected to it. My laptop also makes the USB disconnection sound every few seconds.

I hate to say it but without learning how to read the circuit diagrams and troubleshoot the components, I think it's time to start shopping get for a new phone mate.

[Nexus 4 General] uEih:
Mine is a little bit different from yours.. I get no lights at all unless I try to power it on. Yours seem to have a constant light that shows when it's plugged in. Mine was very low on power probably around 1% when it crashed and restarted then it died while booting up the screen so I hope the battery is just past the drain point and damaged.

I tried connecting it with the laptop, same thing I don't get any sounds or lights at all. Only get a red blinking light when I try to power it on, other than that it's blank.

I did disconnect the battery and tried to turn it on, which it doesn't do because I don't think this phone has a straight source that skips the battery.. When I did that it blinked every 9-10 seconds or so, maybe that means the battery is disconnected.

I did purchase a new battery on ebay as my last resort because at this point there's no other solution. I'd hate to waste my money and it not work again so I'm crossing my fingers on this. Although it's nice to have a new phone I don't need one and I hate to waste a perfectly fine phone like this just because of some stupid issues.

So my situation is a bit different as I knew my battery was almost dead and not half or fully charged like some people here. Not sure what the difference is between plugging it in and having a light automatically blink or stay red vs plugging it in and getting no lights.
