Won't power on

Hey guys, I'm having a problem I thought you might be able to help me with.
I had my phone hooked to the charger. When I went back to it a few minutes later, the phone was powered off. There was also no charge LED lit either.
Now, I am not able to power the phone on at all. I get no LEDs when I plug it up.
I have tried taking the battery out several times. Has anyone else ran into this issue.
Also, I am not rooted, I am running on stock software.

You don't get the slash screen or anything?
Have you tried to get into recovery via adb?
We're you rooted / custom rom name?
You sound bricked

I do not get a splash screen or anything what so ever.
This phone has never been rooted. My original phone was, but after an issue with roaming and 3g I swapped it and decided not to root the new phone.
I have tried powering on with the volume button down, but still nothing. My pc does not recognize it at all when I plug it in either.
Also, I have tried 3 different charges and cables as well.

I had the same problems. I just weighted and mess with the power button and the battery. Steps that I did
1. hold the power button for like 5 second w/battery on phone
2. than while holding the p/button took the battery out and than put it back
I did this like 5 time, than it came on.I don't know what it was luck or what but it work for me. All of this happen before I rooted the phone.

Didn't work
Thanks for the input though.
It might just be dead. Maybe a power surge or something. idk.

Well, I finally got it working. It ended up being the battery. When it messed up, it was plugged into my g19 keyboard. This ended up completely draining my battery.
I swapped batteries with my friend to verify this. It than took over an hour to charge my battery to the point of the Orange led comming on.

Bricked? Help?

I Really didnt even do anything. flashed cm7.0.2 few days ago
with pershoot kernel
been running fine. never overclocked etc.
just few hours ago my phone kept freezing and when i turn it back on it would show black screen, pulled battery rebooted and froze in bootscreen.
wiped dalvik cache wiped cache rebooted been working fine then froze again
same thing happened
repeated the process then forze again so i thought i would wiped the whole thing so did factory reset and it showed something like E:cant mount/recovery/cache or w/e
(i used gmethod to rooted the device.)
....i flashed miui on top of it then flashed kernel and those error popped up again
....i was scraed rebooted...htc logo
for like 10 min...pulled out the battery....now my phone wont turn on... any ideas?
i know the phone is done for real. when i plug into charger nothing comes up
when i turn it on nothing comes up
when i turn it on to hboot nothing comes up
does anyone know where i can get a new motherboard?
i voided the warranty by doing the spring mod
or new screws with void stickers.

It's possible the battery is having problems, i doubt it though, it seems as though youve hard bricked your phone.

does anyone know where i can get the motherboard or better
OEM htc g2 screws with void stickers?

By the looks of things, any number of factors could be contributing to your Desires errors. However, it does seem like you've messed up the partitioning on the Desire Z internal memory and its giving you errors for it.
Try these steps.
1. Take the battery out and plug in your charger.
If the light doesnt come up try plugging your USB cable into your PC to charge.
If the light still doesn't come up your Desire Z is gone.
However, if the light does eventually come on, go to 2.
2. If any light comes up, then try turning it on.
If the screen turns on and you see ANYTHING besides black thats GOOD. go to 3
If the screen doesn't turn on there may be a motherboard issue.
3. Now if you can get it to turn on and not show black you should try this:
3a. Plug it into your PC then from there hold VOL DOWN and then navigate your way to Fastboot. It should say FASTBOOT USB or something like that.
3b. Flash a stable ROM onto your phone via your PC by going into recovery, mounting as storage then copying a ROM over. Then just flash the ROM onto your Desire Z and it should be fine.
If all this fails you should send it to a repair shop. There's no way you would get warranty to fix it at this point.

so ok i managed to get mini usb cable
When i conntected my phone to charger last night the orange battery light came on.
but nothing else.
when i clicked voulme down button then connected it to my computer it vibrated 5 times then green light came on.
And on my computer it showed up as Qualcom CDMA technologies MSM.
im searching everywhere to see if i can fix it. at this point any help would be appreciated.
I did notice that even though the phone wasnt turning on the phone was getting hot? (it wasnt connected to the charger obviously.)
when i did battery pull and leave it out it cools down. when i put it back in and turn it back on it gets hot after a while even though the screen and everything does not turn on.

Do this:
Pop out the battery and leave it for maybe 1 minute.
Then put the battery back in and see if the phone gets hot. If the phone does get hot skip passed 3 and 4.
Now assuming the phone doesn't get hot, plug it into your charger for about 5 minutes before turning the phone on. Try and get into Fastboot/Bootloader.
Once in your bootloader, just navigate your way to recovery and flash a new rom.
If the phone/battery gets hot it means its turned itself on as soon as the battery has gone and the phone isn't displaying anything. You should try just plugging the phone into the charger and turning it on. See if you get anything up on the screen. If you do then just jump into recovery and flash a rom.
Otherwise, if the screen always stays black regardless of what you do, send it in for repairs.

yea it stays black no matter what i do,, but it does get hot though.

Farout.. you should really send it to a repair shop then. The reason why is because you can't do anything to the device without the screen on. You can try and hope for it to boot into HBOOT but you would have better luck sending it off on Warranty or to a phone repairs place.

[Q] Bricked phone? Flashing red LED w/ no vibrations

Background: I was flashing a backup via TWRP, which failed because it could not write to memory. I rebooted the phone and it no longer responded.
Currently: the phone only has a blinking red LED whenever the USB cable is connected. I cannot connect into fastboot. The phone does not respond or do anything. No vibrations.
Is there any possible way to fix this? Or am I screwed?

Been there. No button combinations work nor vibrates at all. PC sees the device, but it is unrecognized. The LED flashes, but that's it. In the end it was power problems, battery and motherboard had lost communication with each other somehow. Thankfully the phone was under warranty and they swapped the mobo.

Thanks for the reply. You think they'll be able to find out (or be bothered to find out) that I unlocked the bootloader? Standard rooting = no warranty problems :\

I guess it depends on how much they want to find out. Although I believe it's pretty much impossible to find out anything if your mobo is dead unless they do some really complicated soldering, which I doubt they would.

Thanks for your help! We'll see how this goes once I get back from holidays. Also, what excuse did you give to justify the phone getting sent off?

Well my case was a little different: I bought the phone second-handed and the guy told me that nothing had ever been done to it (no rooting, no bootloader unlocking or whatsoever). However I found out that it had been and still was rooted, so I recycled it via Sony companion and charged it fully afterward. 5 minutes later it died. When I went to the service center, I didn't tell them much, nor did they ask much. "The phone went to sleep and never turned on again" had enough justification for them. Hope it's enough for you as well.

I had this issue when my phone got water damaged. I left it plugged in for a few hours and it would boot after, though the backlight was dead due to the aforementioned water damage. It might work for your phone.

Phone won't turn on anymore

Hi everyone,
my phone simply won't turn on anymore. It was still working fine yesterday and before I went to sleep I plugged it in the original AC charger like everyday (the phone was on ~50% battery and still working after I plugged it in). But when I tried to wake up to phone in the morning nothing happened. I disconnected the charger and tried to turn on the phone again but still nothing. Then I tried connecting it to my computer but that did not work either. The phone does not show any signs that it is "alive".
I checked the charger and usb port of the phone if their is any visible hardware damage but there wasn't. The phone is only 3 weeks old and was working fine until yesterday. It was running on MDB08M and the bootloader was unlocked so I do not know if I can send it back on warranty.
Anyone here who got the same problem and found a solution?
(sorry for my bad english)

I would try connecting it to the PC and check device manager for any signs of life.

I had a similar problem, the charger died but luckily I had a spare charger

I have tried connecting it to my computer but there is no sign of life.
I guess there is no other choice than sending it back to google with the bootloader unlocked ...

My phone has died almost the same. It started to reboot itself like almost everytime ((( and same with unlocked bootloader.... I had mine for 2 weeks. Now I wonder if its common issue with N5X... Did you send your to repair???

This just occurred on my phone. Working just fine with 80% battery. Started GMaps to get some directions. Hung for a couple of seconds then just turned off. Won't respond to button pushes and won't go into recovery mode either. It's like the phone is dead dead.

All these threads about 5xs dying. I guess I better really start saving for a op3t. ? I've had mine a year and it's been fine but from what I've gathered from reading, someone said that's when they usually bite it is a year+... ?

Not sure if it has anything to do with it or not but I never leave mine plugged in all night. I zap it an hour and roll out... Always scared it would melt for some reason..lol

Nexus 5X won't turn on, bootloop when charging

So yesterday I was trying to make a phone call and the phone went dead. I tried turning it back on but to no avail. When connected to a charger, it just shows the battery for a while and then it disappears and reboots to showing it again only to reboot itself again. Needless to say, I am stuck with a bricked phone. I managed to get it up and running by flashing the stock rom but after update to Android 7.0 the problem came back after like 10 hours. Now I can't even get into bootloader without the phone being connected to a charger, which is a problem because I can't flash anything through charger obviously. Connecting the phone through USB does not work, the phone stays dead like it is out of juice. With that being said I think it might be a faulty bootloader. The power button is fine, so I think we can count this option out. Any other ideas? I am considering taking the phone to the shop where I bought it as it is still under warranty but because it is not Google they might refuse to replace it with a new one or repair it. Is there anything I can do?
EDIT: I sent it to LG.

I had the same issue just a few weeks ago, did you ever get it back? How long did it take? Was covered under warranty?
