Dead Nexus 5? - Nexus 5 Q&A, Help & Troubleshooting

I just got this very neatly used 32GB Nexus 5 and on arrival yesterday afternoon it worked well except for the reboot problem the seller indicated. I flashed stock all over and rooted and installed ElementalX kernel for tap to wake and everything was going well, until last night when it just up and died on me. I thought maybe the battery was drained and I plugged it on the charger. It wasn't charging so I left it overnight. On waking up the phone is still dead. Doesn't charge, doesn't boot, nothing. I've opened it up, disassembled it to check all the parts, and everything looks fine. I also tested the battery by touching the tip of my tongue to the connector and I got the normal tingy feeling indicating the battery still has juice in it. I also checked the two LDIs and they are all still white; no water damage. I'm just at my wit's end now and considering getting another motherboard if that would fix it, but I just want to ask if there is any hope through any kind of fix before I commit to getting a new motherboard.

It might be that ?

Thanks for your response but my phone is not even booting up at all. It's just dead. Not booting, not charging, nothing. Thanks again.

IF you press power and the volume buttons and connect it to computer, did you have in device manager something?
If it was something like QHSUSB ... you can try that (it use and LG debuging software who reflash the nexus all at stock like in the factory) : http://forum.xda-developers.com/goo...-unbrick-nexus-5-stucked-qualcomm-hs-t3043301
If not it was possible that the EMMC is dead
I hope i have help you

I tried that but nothing comes up in Device Manager at all. The computer does not detect the phone in any way at all too. I think the motherboard is dead. I ordered another working Nexus 5 with a broken screen on ebay to use and swap out the motherboard.
Thanks for your replies. I appreciate it.

How To Unbrick Nexus S? Need Urgent Help.

Dear Geeks,
I need your urgent help/advice. i'm three weeks far to my wedding and have a lot of troubles to handle, of course i need this phone.
let me describe the matter i have.
My nexus s is not booting, not starting, nothing.
what i did?
Last night, power button stopped working. I have experienced this 4-5 months ago. I don't know why, the problem has been solved by itself after few days later. i did nothing at those days. the power button came back. (as to my opinion, this is happening due to software problem) Anyway, i have used the market and installed ''fix power button'' application to use volume buttons for opening the screen.
I slept and when i woke up, i saw that phone needs to be charged but i waited. there was %11 something. i tried to handle the power button, pressed many times on it, thought that it may come back again same as 4-5 months ago it happened.
I removed battery and replaced again. i tried this many times. removed, replaced, used the usb cable via AC charger and phone started but there was no result. power button still was not working.
i thought that if the battery runs out, and then, when i charge the phone, maybe this matter may be solved. (ok this was stupid idea)
phone started to charge. when i plug the usb cable, phone was booting and displaying the google and animation and later it was ok to use.
meanwhile i keep on removing battery and replacing battery while the usb cable connected. but when phone starts to boot, i removed battery and replaced again. phone was ok, it was booting. few times it was booting.
but baaaam.
it is now not starting not booting, nothing.
now, when i replace the battery, phone is getting hot, especially sim-card area. i m removing the battery and connecting the usb. same again phone is getting hot, same sim-card area again.
i have waited enough not to connect the battery or usb charging cable. but no result.
what can i do now? what are your opinions?
my opinions/guess:
-i am using 3500 mah lithium polymere battery. maybe the battery died. i m using that battery more than 1 year, around 15 months. i dont turn off wi-fi so i m charging phone everyday.
- phone crashed during booting. and now the phone is totally brick.(i dont wanna believe this, this phone can be usable, believe me i feel it i think whatever happens, this phone can be usable via software installing or rooting... of course if you dont throw it towards a wall etc.)
by the way, my phone was not rooted. no time to root these days. and of course the phone was not starting.
what is your idea? what happened phone? what should i do?
if you reply, i will be appreciated.
A big advice for people reading this, dont remove the battery when your phone is booting.
I hope someone has a solution, since I have the same probelm...
I searched everything and tried every tool in this forum, but no success...

dude, unfortunately those solutions not working on my device.
when i connect charger and i replace the battery, within seconds phone boots itself without power button. it should be this way. removing and replacing the battery helped me to start to boot.
i sense this case a bit different from that solutions.
i need to try with a different battery. my wife has nexus s also. she is very lucky she has no problems i have experienced so far. i will try with her battery.
i think there is a matter with mainboard.
by the way i forgot to say that i dropped my phone last evening. just after then phone was acting that i'm pressing long onto power button. and power button finally stopped working when i remove the battery.
i think this is happened because of dropping the phone from my belly high.
but the last thing i have done which removing the battery while the phone is booting, i wish, i should not have done. i could use it without the power button.

If you have not rooted your device, you should have you warranty, right? Take the phone back to the carrier, and tell them about your problem. o.o Sorry, I'm of no help, but you're in a horrible situation. Wanted to at least give a little help.
Same exact problem here.
2nd of August - mom's phone turned of and just would not boot or prompt at all. The modem heats up when power is turned on or connected.
Tried
The unbrickable methods (but the computer would not detect the device in any form)
A JTAG - I was able to write the recovery and bootloader - assembled the phone and it just won't boot or prompt
Need to try
Another battery to see if it solves the issue.
Removing the xOM5 resistor and converting to a development S5PC110
Tried another battery - no luck
Did the resistor removal and converted to a dev board - Unbrickable now detects the board!
trying to get the device into fastboot - will update

I had the same problem few months ago. Power button had died. While I was able to boot with remove battery and connect to charger option and I was rooted. But after a week I decided to take the phone to Samsung service center to get the power button replaced. My phone did not have warranty. Samsung took few hours to get the power button replaced and it costed me about $7. I think that's the easiest method. They did not have a stock of I9020 power button, so they fixed a I9023 power button.
Any update? I'm curious to see if you get it working. Had the same happen to my NS a few days ago and would like to see if I can get it going again so I can give it to my stepson.

I've given nexus s to samsung service. Actually, power button may be handled by replacing with new one, but with no hope, it will not come back when i read messages about mainboard failure. I will update news whenever it's possible.
we'll see.
I would like to hope it is kind of software matter.
Pls god give my nexus s back, i got extended 3500mah battery.
grrr....

So with the hardware mod - instead of selecting Nexus S -> I tied the Galaxy S in unbrickable - first time I've seen the screen alive! - puts the phone into download mode and I can disconnect from the usb and it stays in download mode! .. when i tried to flash odin I get a "There is no PIT partition" error -> this ofcourse is with re-partition and bootloader update UNCHECKED
When I tried Heimdall it wouldnt let me flash without a pit file. So trying Heimdall 1.1.1 - I get Failed to Access device Error: -3
Any chance some one with an i9020T can do me a huge favor? Use Heimdall 1.3.2 - download your PIT file and upload it here?
reaching for string ends out here :/

The power button had to be replaced. I shorted the connection when ever I had to press the power button during the boot sequence. That's how I fixed mine.

I would like to know if i am able to achieve download mode, what do i need to do, what files and how to install to return this phone to stock?? please help!!!
Take out the battery for a few seconds and put it back; then while holding Volume UP (+) press the Power Button.
See what happens...

Nothing. Happens it don't light up or power on at all. It is not reconized on computer either. It's hard bricked.
Make sure the Battery is charging...
How can I make sure the battery is charging when no lights come on at all? All I do know is I had it plugged in for a while yesterday and it got really warm. But no lights whatsoever. The screen doesn't light up at all neither does the led.
??????
There are no notification lights on the D720, but when you plug it in with a charger, you should see a battery bar on the display.
Other than that, you are probably right about hard-brick.
I, luckily, never had a "brick" on the Nexus S, so someone else with experience may wanna chime in. But Google and YouTube are your friends.
Sorry...

Please help me, i have the same problem
been awhile since any action here. saved mine with JIG method once but this time it won't work ??!(why) , in search of a solution again! -> hardbrick #2 on this device!
You guys can try a USB Jig. If that does not help, I think JTAG is what you need.
Jesus... just to revive this thread (and this concept of hard bricking), I think I just accidentally bricked mine as well.
Here's exactly what I did:
One moment, it was working spectacularly - fully stock, but unlocked. I had just listed it on eBay, too.
So I ran a factory reset on it (from the Settings menu), also "erase USB storage".
Then, after it shut down for the reboot, I pulled the battery.
...
That was it. Now it doesn't turn on for anything whatsoever. No device detected on USB when plugged into PC. Remove, replace battery, hold VolUp+Power, nothing. Plug into power adapter, nothing. Nothing at all.
But the back does get lukewarm after a minute or so, as if it's alive in the head but frozen, unable to start the bootloader.
WTF? I also have 2 more of these Nexus S 4G's, and both of them seem to have Flash storage chips that exhibit the same behavior when their chips are placed in (this) working motherboard. They can't boot. When I try to "hot-flash" it by booting the bootloader then swapping the Flash chips, they can't flash anything (this is probably to be expected). So, if I can get my ONCE-WORKING phone back to life, there's a good chance I can get another working as well (one just has a cracked glass, otherwise working mainboard & peripherals).
It's old, yes, but it's a damn shame to E-waste these things for a stupid software problem like this!

Can you get into recovery mode?
Hi,
I have the exact same problem.
I cannot get into recovery. I tried Power + Vol. Up but that did not work (yet).
Did you leave it plugged into the wall charger while doing this, Braddison?
Also it does not show up on PC.

If I remember correctly I had it on charge and held down power and vol up. It did take a couple of minutes continuously holding down the buttons. Been fine ever since
If that fails try power and volume down for about 30seconds, I'm sure that's meant to hard reset phone
Thanks for your quick answer. I will try once more.
Same dead HTC One Mini here...two days ago the phone suddenly turned off (with somewhat of 80%-90% battery) and since then its dead. No LED, no charging, it even doesnt get warm when its being plugged into the charger. Pressed Power+Volume down (plugged or non-plugged) more than 2 minutes, and also Power+Volume Up more than two minutes.
adb shows no device. If i plug the phone into an USB-slot in a linux-machine dmesg doesnt says anything. So its dead or not? Since its not more than a half year old it should have warranty, but i think i wont get my photos and stuff. So this is an advioce to myself: never ever buy a phone without micro-sd-slot again!!!
cheers, jennix

I would try again after putting on charge for a few hours, ensuring that power and volume down are pressed simultaneously. i have read that its best to do this while in a bright room or shining a torch on the sensor, seems strange i know but its worth a try
good luck

hi all,

htc fixed it on guarantee (although i flashed a cm11-nightly)
the problem was: a damaged mainboard, which got replaced - took about two weeks..

thanks! Just sent mine to HTC, hope they fix it within warranty. Can I ask if ur data on the internal SD is stil intact or did you lose it all? And again someone with cm11 installed. Anyone with Sense had the same problem?
I have the exactly same problem, my phone was rooted with CM11 nightly when it died. I sent it to my carrier, but now they want me to pay 200$ for a new motherboard, because they found it was rooted and the warranty is voided. Even when I pay 200$, i still will have no warranty. And I had more than 1 year left. Is there a problem with CM11? How comes that they replace it for some people for free, and for some not? Please, give me a tip how to proceed and do I really have any options from this point?
These horror stories make me wanna stick to stock based roms. I'm a big fan of CM, but not if there's a chance it could fudge my mainboard.. real shame
or is this another example of another design fault with this phone?....

As they have to replace the motherboard it is an hardware issue, where I live rooting doesnt void warranty if there is an hardware issue. They have to give you warranty. Could you ask your carrier what exactly caused it and why the motherboard had to be replaced?

Hey. I sent it directly to AVARTO (service center here in Germany) they too wanted to charge me (around $ 240). Then I asked what exactly the problem was and they revised their statement. Sent it back for free within warranty. On the repair sheet it than said "not turning on. constantly".
Hi.
Another dead mini. S-OFF, TWRP, CM11.

Nexus 5 Repair gone wrong... !

Hey Guys,
Wondering if anyone on here has any ideas....
Basically, I replaced the screen on my girlfriends Nexus 5. Went through one of the many tutorials on youtube and to my relief it turned on and everything worked fine.
This relief was short lived. In about 30 minutes, the phone turned itself off and then wouldn't go back on. This morning, I took it apart again and checked all the connections and it all seemed to be ok.
Now stuck!
Any help, much appreciated!
The phone doesn't power up at all? If your computer is running windows, connect the phone to the computer and look for any new devices in device manager. If you see something for qhusb bulk, the phone may be bricked.

Nothing at all.
I'd have been less confused if it hadn't worked initially.
Try different USB cables and USB ports when connecting the phone to a computer.
The battery could have completely drained for some reason.
Connect the phone to a 2 amp charger and leaving it charging for 2 to 3 hours, then try to power it up.
If you have access to another battery, try swapping out the battery.
I'll give those ideas a go.
Thanks for the help man, so appreciated!
So, had no luck so purchased a new battery. Put that in this morning, and it's still not working. However, it IS showing when I plug it into a PC which it wasn't doing before.
When I first plugged it into the charger the notification light at the bottom flashed about 5 minutes later.
Was the LED notification RED? Was the screen replacement OEM or non-OEM? Sometimes they replacement screens are questionable.
When repairing a Nexus 5 cracked screen, I have bought a used damaged (Screen good condition) Nexus 5 from ebay (Bad ESN, Water Damage) and just put my Motherboard and battery in it.
With a the new battery in the phone, leave it to charge overnight and see what happens in the morning.

Is my phone dead after falling on the floor, need confirmation.

Hey guys,
After two years of constant care, it happened... the drop of death.
A perfect hit on the floor, screen first, perfectly parralel to the stone floor, with the neat "Poc!" sound... :crying:
My phone now does not turns on. Does not vibrate when I plug it and the computer does not detect it.
That's a perfect brick.
I disassembled it and re-assembled, in case of there was a loose piece or cable, but without success.
Is there any chance that it's only the screen, or is it, as I suspect, the end of my beloved OPO?
Thanks for your advice.

Well well well.... small update.
The phone is finally partially alive.
I just tested to plug it without the battery in and.... I had the small vibration and OnePlus boot logo. But of course, as no battery, the screen turns black right after.
But.....
If i plug the battery in, the phone will turn on (I did not say Android booted ).
But only if:
- I plugged once without battery, then unplug
- I put the battery back in place
- Then I re-plug the USB cable
Following this, I can:
- Enter TWRP (fully functional, I can backup my rom, wipe caches, etc... and all the buttons I tested were OK, touchscreen seems fine) / (Vol down + plug)
- Within TWRP, ADB sees my phone as an unauthorized device.
But I can't:
- Enter Fastboot mode (Vol Up + plug)
- Boot the phone up:
- Even within TWRP, reboot does not work
- As long as the battery is in, if I power off the phone, it won't turn on again until I remove the battery and do the first plug trick first.
So there is hope!!
Can it be the battery?
If I am on TWRP (with both USB cable and battery plugged) and unplug the USB, the screen stays on, but becomes unresponsive and only removing the battery can turn the phone off.
Or is the phone somehow bricked on a software standpoint? And can be unbricked?
Side note, when I first plugged the phone and it turned on, on the Computer, it installed a driver called "Care Suite Emergency Connectivity"

No, just tried out without battery. I did but that's tricky. Once you remove the battery, you really need to push the power button first before plugging in the cable, seems the mother board needs to discharged in some way first.
I called a repair shop, the battery might be faulty and put the mobo in security mode... But as I can't access fastboot mode, they said it could be a part of the phone's ROM which is damaged.
Any way to use adb through TWRP to try to dump all partitions to see if any of them are damaged?

Display works perfectly fine at least under TWRP.
The problem is somewhere else, maybe on battery or ROM (not the OS)

Quick update.
There must be a problem with the mobo.
I ordered a new battery that arrived today.
With the new battery, the phone boots up Android, but after some time, it freezes completely.
If it does not freeze and if I try to power it off or reboot, it just shuts down and will never reboot unless I do the battery trick again (remove and put back in place).
SIM is recognized but I don't have network.
I did not manage to get a GPS fix.
Fastboot works, I flashed the stock LOS 13.1 image. But it did not change to the freezing behaviour, and even under fastboot, a "fastboot reboot" just powers off the phone.
That's frustrating!!!
I think it's dead for good. The only reason I see for such a strange behaviour is a shortcut somewhere on the MOBO, maybe a damaged soldering.

No, but I discussed with two of them on the phone.
Considering the price of the phone, it's not worst anymore to repair PCB if it can be.
I will go for a Oneplus 3 I think. There is an auction ending on eBay soon and it's still at 170€... And with the 5T coming out, there will be a lot of other good options in the coming weeks.
I have the Oneplus 3 now... Thanks @Mr.Ak and see you guys!!
