Hello All,
I hope this is the best forum, but please give me advice if it is better somewhere else.
I recently dropped my Nexus 5, cracking the screen. I am fairly DIY, so I ordered a new screen on eBay. Although I had never opened the Nexus 5, I followed some online guides, and I thought the process went fairly smoothly. However, after it was all assembled, the phone was completely dead. I switched back to the old screen, still dead. I picked it up to try again. I can put the phone in to the following states (with the back cover off):
Battery Connected, USB Power - Solid red light. Unresponsive. Power + Vol- just cycles red light
Battery Disconnected, USB Power - The screen powers on, shows the "starting to charge" logo. The device power cycles approximately every 5 seconds. Holding the power button will show the Google logo (aka, startup), but continues to power cycle every 5 seconds.
Battery Disconnected, USB Power, then battery connected - With the battery disconnected, it will show the charging screen. I can then connect the battery and completely start it. The device appears to be fully functional (sans the rear speaker, but I am not concerned about that at the moment). The battery always indicates 0% (Unknown). However, if I unplug the USB power, the device will stay powered.
Any ideas on what the issue could be? Bad battery? Bad main board? Or, ideally, a loose connector.
Any insight would be appreciated.
Dan
Update: I am unable to replicate the red notification light. Now the phone is unresponsive if the battery is connected.
Could be anything really. Only a professional would know what's the issue after examining the device.

Battery dead, not charging, stuck on "low battery screen", bootloops with forceboot
Hello people, this is my very first post on xda, even though I've been lurking around for about a year. The community has helped me a lot, I'd like to thank you all for that.
Back on topic though! My error seems to be very similar to the one here.
I was watching some YouTube, battery sitting on a respectable 85%, when it suddenly shut off. Not the usual "shutting down for low battery" kind of shutting down, it was istantaneous, more like the battery was unplugged from the phone. Which is clearly impossible. I tried to boot it using the power button to no avail. I connected it to the charger, and the "the battery is too low" screen popped up. I left it at that for about 45 minutes, then unplugged from the charger and tried to boot. No success. The battery didn't even charge; the charger should be is fully working.
So I tried leaving it plugged to the charger and force boot the phone via volume down and power button; it attempted to boot, but stopped midway through, bootlooping until I unplug it, at that point it shuts off again.
The loop goes like this: OnePlus white logo (normal when you boot), radioactive kernel loading, reboot and repeat. That happens, again, until I unplug it from the charger. Then it shuts off.
EDIT: If I try to get into bootloader instead (volume up + power), after about 8 seconds of me pressing the buttons the screen just shuts off and doesn't react to any more presses (even while plugged). If I unplug and replug it to the charger, I'm back to square one (low battery, please charge).
PC doesn't recognize it. It makes the "the battery is low" screen pop up, but nothing else.
Here's some phone information in case you need them.
Phone info:
Rom: NucleaRom 1.3 (+ Radioactive kernel which comes with it) got it from here
Xposed modules: Youtube Background Playback, AdAway
Root: Yes
Thanks in advance everyone.
I doubt it would be software related if it does it even when in bootloader. It could be the problem I had with my nexus 7 a few times. I needed to charge it like all day for it to even turn on. Either that or faulty phone/bad battery. I hope it's just dead

Hello there, thanks for taking the time to reply. Yesterday I worked all day to try and make sense of the problem. I could have just bought another phone but I'm fairly attached to this one so I went deep.
I was fairly sure (like you) that it couldn't be a software problem, so I looked at the logic board of the phone; turns out (correct my poor technical wording) the bracket (connector?) for the battery on the logic board was coming off from the motherboard itself (the battery was indeed attached to the bracket, the bracket was just coming off of the board). What I did was just reposition the bracket and pushed it down with a bit of force on the board, then replugged the battery in the newly restored battery plug, and tried my luck. It booted! Back at its original 75%-ish.
My only guess would be that due to a fall the bracket got misplaced, but stayed close enough for it to still make contact and never actually shut down, until yesterday. That was... Quite an interesting ride.
Thanks for replying, it was indeed a "faulty phone", but I just couldn't leave it at that without trying
I'm glad it worked out for ya
Not work at all ...
My phone its show the logo on charging or low charge but its stuck for this for while full battary is empty... When I plagued in charger the same show charging logo with indicator but not charging its suck on that logo to .......then I charged the battary externally then put the battary try to open its show only a (powered by android log ) stuck on this ......I cant go any recovery modes ..fast boot mods... Only show this one or charging logo if battary low that logo to ... I try to get adb driver on my computer its also not show because of not get recovery modes ........
Any other idea to solve this
So i recently picked up an XT1254 for a great deal. The phone is pristine, not a scratch on it. It looks brand new. It is totally unresponsive. If I plug it in the light on my charger turns from blue to green, telling me it's fast charging. But nothing from the phones LED. Also if I place it on a charging pad, color changes as well. I tried both options over night and still nothing. The phone does get warm (usual amount), leading me to believe it is charging the battery.
Holding the power button - nothing (no vibration, no moto logo, no LED responce)
Holding power + vol down - nothing ( = )
USB to PC - phone is not detected at all (I have ADB and current moto drivers installed)
I opened it up, and everything seems to be in order. No loose connections, no water damage. I checked the battery, and it reads roughly 2.5 volts across each pair of pins. Should it be reading 3.7-4 volts across each pair?
I unfortunately don't have another phone to check the MB, battery and LCD against.
I don't have a SIM installed in it, but I doubt it makes a difference?
Any ideas or advice would be greatly appreciated! Thanks-

Quite low for li-ion/-poly, I don't think it ever sees 3v or under in normal circumstances. It might be well into "damaging the battery" territory at this point, and it should certainly be higher after charging it for a while...might be a goner.
Have you tried removing the battery completely and running it off the USB cord? I would expect it to, if nothing else, bring the screen up complaining of a bad/missing battery. That said, I've never tried unplugging mine to see what happens, so no real idea.
I would suggest trying to fabricate a factory cable (which would provide power directly, ignoring battery status), but I don't know if post-OMAP Motorolas are physically configured to use them. If they aren't, it'll do nothing at best and burn up traces at worst : \
Also, holding Vol - while plugging it in should bring the boot menu up, regardless of available battery charge (therefore serving as a quick test to see if the power button is the problem). But that might go out the window as well if the battery is deader than a doornail.

It doesn't. When I fresh-install a ROM, I remove my SIM card to make sure none of my data gets used before I can turn various unwanted syncs/auto-updates off. The phone doesn't care at all, and nowadays Google isn't too whiny about a missing SIM either.
Hello guys.
Sorry for reviving an old thread, but I have similar problem with my Droid Turbo. During the replacement of the battery and speaker, I noticed oxidized resistors near the proximity sensor (which wasn't working since the purchase of the phone second-hand). I have cleaned the oxidized residue with ethanol and assembled the phone. After pressing the power button, the touch buttons light up and phone was vibrating every 20s but the screen was blank. So I disassembled it again to check all the connections but everything was fine. Since then, the phone won't even vibrate, just heats up a lot after holding power button. I have tried both batteries, speakers and also powering the phone without battery (only power cord connected). Both batteries are shoving around 3.8V.
Do you please have any suggestions how to fix the phone? Or should I assume that the motherboard died?
Thanks
Hi,
I got a Z3 which was described as having no power and just flashing red LED when power button is pressed, after being dropped flat on the floor in a gel case.
The phone is in good condition with no external cracks or breaks and the only damage is the USB connector flap doesn’t stay closed.
I decided to take a chance on it thinking maybe the battery connector had come loose or similar.
When the volume up button and power button is pressed it vibrates 3 times.
When the off switch is held it also vibrates - but not every time.
When charger is connected the red LED sometimes comes on for 5 seconds then goes out.
When trying an a stiff apple type micro-usb lead, a couple of times I got a solid red LED. I left it on charging for 24 hours but the LED remained red and it was still the same - no power.
So I suspected maybe the micro USB connector may have damage.
Not detected by windows or Xperia/PC companion.
Sony Mobile Flasher just says “Device disconnected”.
So I decided to open it up.
It had previously been opened up and possibly the battery changed as is had horrible double sided sticky stuff holding the battery in and the back cover to the battery - cheap shop fix to avoid getting the proper adhesive seal?
The battery connector seems loose and I couldn’t be sure if it was connected properly.
The battery voltage was about 2.70v so I was thinking maybe below what would be correctly detected.
I decided to boost charge the battery for a bit.
At 3.30v I put the battery back in but the behaviour was the same - maybe the LED flashed red a few times at various points.
Any advice what else to try?
You help much appreciated.
Thanks.
try removing the battery plug in the phone to your pc and start pressing the power button rapidly if it gives a green or a blue light then your is phone is ok it might just be a battery problem but if not
You are in a heap of trouble
In most Cases the red light only cames on when there is somthing wrong inside the phone
it can be easy as a battery replacement
Or worse like mine it can be an Power Management IC that is shorting out due to lose or bad connections
Hope this helps
Was accessing dual recovery to wipe for a clean slate and it had a sudden death. The charging LED was no longer lit. Left the phone alone for about 2 weeks to let it drain but no response. Decided to order another battery for testing thinking it may have been bad, still no response. What I did notice is that if the battery is removed and the charger is connected, the LED blinks red constantly. However, if I were to attach the battery connector the LED will stop blinking after a few seconds. Is this an issue with the motherboard itself or can there something be done to bring it back to life?
*Update*
Let it charge for a couple of hours. Still not turning on but getting some response at least. The phone will now vibrate in sets of 3's if I hold down Power and Volume +. When trying to charge, the red LED will come on for 5 seconds then off every 5 seconds. When connected to the PC, it shows as unidentified USB, but the sound of it being disconnected is constantly going off. Not sure if anyone knows how I should proceed from here...

Hi my phone is a D6603 and i was having a very and inusual problem like you Sudden death with some response vibrating in sets of 3's. My problem was resolve when i remove the sim then press the reset button 2 times in a row but slowly and the phone was starting again
I dont remember if it was or not conected try both ways
Back up your files and start working to keep it warm and dry, remember that it can be water damage. I downloaded minergate and began to mine in easy difficulty so that it would not become slow, but at the same time to keep it warm. It is only to dry if it was damaged by water, I do not recommend anyone to mine with a smartphone xD
I have never had any problem with my Nexus 5. It is now my standby device. Accordingly it doesn't get used much. One day I left it ON and didn't use it for 2 weeks. When I picked it up again it was OFF and didn't want to turn on. Naturally I thought the battery had drained and put it to charge.
Instead of the battery symbol on the screen (indicating it is being charged), I get a sequence of 8 red blinks on the bottom notification light (which is just above the charging port), each blink lasting 0.5 seconds, then 0.5 seconds off (so total duration of blinking sequence is 8 seconds), then 1.5 seconds off, then blinking sequence starts again.
I left it connected to the charger for 2 weeks. Nothing changed.
I then replaced the battery with a brand new OEM battery, same thing again.
I cannot get into recovery mode nor is the phone recognised when I connect it to the PC.
Any ideas? Anyone knows the meaning of this blinking sequence?

what is the current state of the phone? do you just get the blinking when charge cable connected? no boot loop ?
So currently the phone doesn't switch on and cannot be charged it would seem.
There is no bootloop.
And yes, the blinking only goes on whilst a charging lead is connected or whilst it's on a wireless charging cradle. No blinking when removed from the charger.

you said you replaced the battery , I would check that connection , try removing the battery if possible and reconnecting it. Try the old battery too if you still have .
In my experience i'v seen that blinking light in other devices when they overheat.
I only replaced the battery because of the blinking problem as I suspected a deep discharged battery. Anyway the connections are good. 100%.
I never had overheat issues on my N5 as it was just used for basic functions, no gaming etc. I wouldn't imagine the device had overheated while it was left unattended on my desk, and there definitely is no overheating happening now as it doesn't even switch on...

sounds like your hammerhead finally checked out ... the old saying goes " if you don't use it, you lose it " .... try all combinations like hold power and volume down at the same time for 10 seconds , power and volume up ..etc
other than that i'd take a multi meter and make absolute sure you have power to the motherboard , then if you still do, it could be a short ..
if you want to go even further, a complete tear down of the phone, check for corrosion ( whitish residue on terminals and motherboard ) clean off with toothbrush only ( no water or liquid of any kind ) be careful removing ribbon cables and re-inserting them ... you can find lots of stuff on youtube for that.
good luck
