[Q] Brand new Nexus One can't be powered on

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.

won't turn on/can't select any boot options

I have a new Motorola Atrix HD. I was using it and the screen went black. i hit the power button to unlock but nothing happened. i plugged it in but nothing happened. i took the back off to see if the battery was disconnected. I didn't know the battery was different than other phones and ripped the power cord connecting the battery to the phone when i took it out. lesson learned. Ordered a new battery and installed correctly. phone won't turn on. The green charge light blinks when i plug it into the wall and then stays on for about 20 seconds and then the phone tries to turn on but while the motorola icon is illuminated, it cuts back out and repeats the cycle. I left it plugged in for a couple hours and still the same thing. i tried holding in power and volume buttons for the boot screen. if i do that just as the phone attempts to turn on i can get the screen up and scroll the list of boot options with the power buttons but i can't select any of them and the phone cuts out after the same amount of time. Everytime. When i plug it into my laptop, the light blinks on and then stays on like with the wall, but the phone doesn't attempt to power up. Please, any help would be greatly appreciated. i have read a lot of forums where the battery was acting up because of the chargers people were using. The difference between my situation and those of the people i read about is that my boot screen cuts out and cannot be used. This all happened 2 days after my exchange period ended and because i took the back off myself, best buy won't have anything to do with me so i'm on my own and cannot afford another phone right now. Thanks in advance for your time and concern.

Is it possible that the that connection between the power cord and the phone itself is loose or damaged? I'm just guessing here as I have never opened up the back of my phone.

I would check your battery terminals then leave it to charge if it does. You could also try a factory cable. Another thing would be to try fastboot while connected to your laptop and see if it stays on, and if it does, try reflashing all partitions.

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.

My HTC one M8 won't turn on.Need urgent help!!!

Hey guys! My HTC One won't turn on. My phone was on 17% when i connected it to charger.After sometime i checked my phone to make sure it was charging and everything was alright my phone charged to 37% when I last checked. After 2:30 hours i checked my phone and it was showing charging LED but wasn't on.I tried to turn it on but it didn't turn on. Also no when i connect my phone to charger it won't show charging LED. I tried Volume up,down and power button method, and i also tried volume up and power button under a bright light. It just won't turn on. I connected my phone to my PC. Its only show a QHSUSB_BULK HS-USB QDLoader 9008 Driver. Any help would be appreciated.
Note: Its a rooted Sprint HTC one m8.

How long did you hold down the power & volume buttons for? Did you hold all three buttons down at the same time?
Also, what ROM & firmware were you on? Or were you stock rooted? How long have you had the phone, and was it new or used when you bought it?

I had a similar problem a few years ago. My phone screen would turn off on its own. I would then have to restart it Finally I noticed that the Orange charge LED would not show when plugged in to a power source. When plugged in to a source the Orange LED showed for a moment, then turned off. Once dead, I could not charge it to restart. Sent to HTC and they said the motherboard died. Initially charged me 300 dollars, but I told them it was better for me to buy a Nexus at that price. They lowered it to 150 dollars and I got it repaired. Now days, again I am noticing the screen going dark on its own, but it is difficult to enable the screen by clicking the power button. The phone is on, but just dark screen. Currently I am rooted and S-On with Stock ROM.

Connect your phone to 2-2.5 amp WALL charger(original or another OEM original, original chargers are sold only in brand shops), and cheap cables most of the time don't work either.
wait 15-20 minutes and hold power button + vol up + vol down for 30 seconds.
Same thing happened with me but I was in recovery on low battery(while plugged in). You will also lose simlock if you are international user.
Check the screenshot in this thread, if you have the same thing showing on Windows Device Manager then it's most definitely a flat battery.

Phone Switched Off. Now Refuses To Charge (?)

So, The phone was working fine in the morning. I remember charging it in the morning as well. After a few hours, the phone suddenly switched off as I was saving a number. I thought maybe the battery was used up (?)
So, I put it to charge. But I do not see any charging screen or indicator. All I see is the notification led blinking 10 times! It's been charging for an hour now. No response from screen. The led blinks again for 10 times when I long press the power button.
Please respond on what may be wrong!

First of all, which model?
Second, does the phone connect to your pc?
Third, what about warranty?

If bootloader is locked try taking it to your nearest service center..

It's the Le Eco Le 2. And connecting it to the pc gives the same blinking lights. Although I did hear a device connecting sound alert..
And the led blinks continuously for quite some time before going off.
And I purchased it online last year november.

The problem is the 'nearest service center' is hours away. I can't take a leave at work for now just to give this to the service center. That'll take some time. The downside of buying phones from such companies I guess

Unplug your device from the charger and let it cool for 10 mins, after 10 min try to switching​ on the device by holding the power button for 10-15 seconds

I tried. The device is already cool. I checked the device after plugging it for a while. It never heated up indicating it's not charging at all. I remember it wasn't completely discharged because i charged it completely the day it conked off.

Are you able to boot into fastboot or recovery ?
If not, then your device is bricked and you have no other option other than visiting your nearest service center.

What's the key combination? And for how long?

Volume up + power for recovery ( 8-9 secs)
Volume down + power for fastboot ( 8-9 secs)
Or press the power button for 10-15 secs for a reboot

No response at all. I see nothing on screen and no notifications light does not blink. It only blinks continuosly if i connect it to a power source.
Isn't there a hard reset button slot ? I remember the older phones with non removable battery having them...

No hard reset button, you can only hard reboot the phone by pressing and holding the power button.

Just found out ,the phone connects to the pc. It automatically goes into Qualcomm HS-USB QDLoader 9008 mode. Is there any way to flash,reset it?

am have an issue, my phone went off on low battery on Sunday, the battery actually drained, was blinking led light before, when charged , but now nothing is displaying and the phone wont boot up! charged it last night still same issue, charged again this till afternoon, noticed only the lower part of the phone is hot and the charging port, but wont come up. held the power button for 2 minutes nothing, please i need help:crying::crying::crying::crying::crying::crying:

Just to tell that my phone was also in this mode, red blinking light, and qhusb mode in computer. I got out trying key combinations and connecting to pc usb.
the last one that worked was pressing power for 10s and then connecting to pc. then the letv logo apeared and it booted normally

I had the exact same issue a few months prior. You'll need to change out your USB-C daughter board or your battery. One of them has got shorted.
