I have a T-Mobile Note 8 that will not power on. At least I think it's not powered on.
I put the phone on the charger last night and this morning I woke up and the screen is black, no lights, no sounds, no vibrations. I've tried Holding PWR + VOLD, PWR + VOLU + BXBY, and PWR + VOLD + VOLU + BXBY for 20 seconds each. No response.
I also tried putting it in the freezer and retried the above. That fixed an issue with my Note 4 so though I'd give it a try.
Normally I would just pull the battery, but now that would void the warranty and be more work than it's worth.
What else can I try?
Different charger/cable
Make sure the charger and cable function properly, try them with another device, check the usb not to have moisture, sometimes it takes several hours for moisture to disappear, if all these options fail, take it to claim warranty

I have a brand new Nexus One bought on last year April. For some reason it wasn't to be used. Yesterday, I got it out of the package and charged it for ready to be powered on. Unfortunately, it reacted nothing as I pressed the power button! I took out the battery and put it into other Nexus One, it showed the battery was 100% charged.
I took back the battery and repacked it to this new Nexus One. I tried to press the power button more and more with data cable connected pc. Nothing happened. Just one time, the sceen lighted on and the "X" in four colors appeared! I didn't know why it was powered on. Maybe I pressed the trackball or volume up/down buttons, God know it.
The X sceen lasted almost for ten minutes and then sceen was off! Yes. It shutdown! I can't power it on anymore!
It seemed the hardware was OK. It may be the locked by the outdate android system. The android prestored in this phone is version 2.1.
Any advice is welcome. Thanks.
Can u you go in fastboot? Press power button+trackball..if so then you can recover your phone by unlocking bootloader and falshing custom recovery.
Sadly, It can't be power on and go in fastboot by pressing trackball+power button.
Any more advice?
Check the battery terminals just to make sure they're not dirty.. Sadly, you MUST be able to at least be able to boot something (hboot/fastboot) in order to troubleshoot anything software related. Sounds like you've got a hardware issue that could be one of (literally) a million things.
Sell it on EBay for parts. You can probably get $50-$60
you could try pressing pwr/vol-/trackball all at same time, hold down for around 30 seconds to make sure
commonly known as 3 finger salute
try power on without sdcard by manual methods and plugging in and plugging in with no battery
I have seen a video on YouTube on how to fix the power button which is known for messing up and how to turn it on. Search YouTube
Sent from my Nexus One using XDA App
is it that the power button is not working? that would be weird for a new phone though.
have you tried to turn it on using the "jump start" method?
connect the cable. led the charging led come on. remove the battery, wait for the led to go off (while cable is still connected) then pop the battery back in.
see if you can get it to start that way
When you plug charger cable in your Nexus, does the orange or green LED go on?
If one of them does and stays (green for full battery, orange otherwise) - then your problem is most likely the power button. It may not be the only problem, but at least the one that's stopping you from turning on your phone. You can try "jumpstarting" it by inserting battery while charger is connected.
If you don't see LEDs when plugged in - your phone is done.
If you see blinking LEDs - battery terminals might need cleaning/fixing, it usually happens when the battery is out of the phone.
Hello,
I am currently using an ATT branded 64 GB HTC One. The Phone is locked and stock except for a few play applications I've downloaded
Nearly every day that I connect the phone to the charger for an extended period of time I will come back to it and it will be frozen, the notification LED will be solid just like its charging normally but the screen will not wake, when the phone is disconnected from the charger the LED stays solid red as if it was still plugged in. At this point I will hold the power button until the phone powers off (or at least seems to, the screen backlight is not on and the LED goes black) and then hold the power button again and it will boot. The more serious problem I've been running in to is after powering down the phone down sometimes it will not power back on again regardless of how long I hold the power button for (I haven't gone over 1:30 of holding the button often but I have tried it). The phone seems dead for either a few minutes or a few hours. Here are some other observations I've made...
- I've had the phone "lock up" on 3 different chargers, HTC bundled charger, generic USB, and the one bundled with my Nexus 4.
- I've thought maybe the phone isn't charging while I am away and when the phone will not wake up maybe it is completely dead so I've hooked it up for about ~15-60 minutes and tried powering the phone up on the above 3 chargers, a Lumia 920 charger, car charger, and charging off computers USB port. None of these seem to have any affect on waking the phone up.
- The time between powering off and when it will power back on seems to be getting longer? I am currently with the dead One, it died about 12 hours ago before bed, tried to power it on last night and again this morning after leaving it on the charger. The closest to powering on that I got was the screen flashed white for a millisecond. Tried to power it back on many times this morning and no go.
- The phone hasn't frozen away from home, but I've only charge it from USB from my PC at work.
Right now I am leaning toward contacting ATT to see if I can arrange an exchange, I'm out of ideas at this point.
I tried to wake up my Touchpad last night and nothing happened. So I pressed the power button and nothing. I held the power button for 15 to 20 seconds. I felt the tablet vibrant once but it never came on. So I held the power button another 20 seconds and felt it vibrate, but still nothing. I also had it plugged into the HP power adapter at this time.
I unplugged it and tried pressing and holding the power button a few more times. I noticed that without the power plugged in I don't feel it vibrant when holding the power button.
I'm trying it with a 2amp Samsung adapter with the HP cable. But after having it plugged in an hour it still doesn't powering on.
Any other troubleshooting steps I can take?

When the battery is completely depleted it takes a long time (24+ hours) to get it up to speed again. Leave it plugged in overnight with the stock charger, or touchstone..
The button combination that reboots is power button and home button, held together for up to 10 seconds. That should get you to moboot.
Good luck.
Ahh... I didn't hold the power and home buttons together for 10 seconds. After doing that, I got it to reboot and back into Android.
The battery is at 100% and it was on the charger when it decided not to wake up anymore. But it's alive again. Thank you very much.
I was with Telus, and entered unlock code for carrier unlock few months ago, and 3 days ago. My HTC battery drained, it will no longer able to turn on, when I plug original cable and charger, no LED, and screen also blank as did not turn on at all. I did research on google, noticed lot of people had similar problem. I follow procedures at XDA below,
1. plug original sync cable and charger to phone for 10-20 minutes (I plug it over a day)
2. press and hold at the same time 3 buttons at the same time POWER, Vol +, Vol - for 2 minutes, i also tried 5 minutes as well.
3. after that release all buttons at the same time.
no luck, nothing happen.
I also tried plug sync cable to computer, I hear USB cable plug-in sound on computer, charged also 30 minutes, and did step 2 & 3 again.
same result, nothing happen as well.
Is there anyone can help me for this? Because I just went on vacation and got back, I was not able to backup all photos during vacation, so I do not want to lost all data and photos in phone.

I answered you question here >>

Try holding the power button and volume down buttons down, while holding the proximity sensor directly under a very bright light (sensor is top left on phone)

I did the same thing, it won't fix.:crying:
Wow, my phone stopped charging. I have TWRP 2.6.3.3, and tried ARHD 81.0, Maximus HD and Stock Rom to see if my battery would start charging again when on, yet it makes no difference.
When off, it does charge (official HTC wall charger, and others as well). For a couple of seconds you see the empty horizontal battery (no filling animation though) with a solid red led and after that it changes to the vertical battery icon which has a filling up animation and a less bright red led. After a couple more second it changes back to the horizontal battery icon, and this process loops indefinitely.
I have tried:
Charge for 20 minutes, then hold the power + vol up + vol down button for 2 minutes, multiple times - doesn't work
Charge for 20 minutes, then hold the power + vol up + vol down button for 2 minutes under a bright light, multiple times - doesn't work
Different chargers, including usb on my computer - doesn't work
Various reboots from bootloader and fastboot - doesn't work
The thing is - it IS charging when off, so the battery can't be broken, right? This must be a software problem. Should I try to flash another kernel or something?
I am facing the same problem. Even I tried changing ROMs. I changed from ARHD 81.0 to Maximum 41.0 and now on crdoid (cynogenmod) but it is not charging. It is exactly in the same state as yours.
I inquired with the HTC service center in my city. They said they need to change the motherboard of the phone which will cost me Rs. 19000 ($310). The amount might vary in your country. I hope there is another solution to this problem except changing the motherboard.

Hi Rahulwadhwani,
I have tried everything, finally decided to go back to stock, because you have a 24 months guarantee period on your device. Tonight I'm gonna bring it back in the shop where I bought it.
If you start reading from here, you can see how I brough it back to stock, I can imagine you face the same things as me when you decide to bring it back to stock too.

I went to the htc service center again. They charged me Rs. 1350 (approx $22) and chanted the charging port of the phone. It's working properly now.
By the way, my phone had a custom rom and was out of warranty too..

That's good news, glad you had it sorted out!
I have tried everything as well. And since it DOES charging when off I tend to think it's not port/charger problem.
I chatted with HTC customer support and they told me that developer working on software fix for that which will be distributed over the air (OTA updates). I'm not confident how true is that, but I decide to switch to Maximus HD room from Revolution HD, since the former has OTA updates support.
Things I've tried so far:
Plug-in charger -> power off -> press and hold Power button + volume down for 15+ seconds and put proximity sensor under the bright light
Plug-in charger -> power off -> let it charge for 10+ minutes -> press and hold Power button + volume up + volume down buttons for 2+ minutes -> release them
Reboot the phone into the Safe mode (while charger is plugged in)
Different chargers, car charger, connect to PC
And just for the record - it won't charge even if it's off if Fast Boot is ON.

Let's hope they will come with a software fix. I wonder what that is gonna be though, I have tried so many different roms and firmwares, they made no difference. Other people with the same problem had it fixed by replacing the usb port or even the motherboard.
