[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

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.

[Q] Is my Nexus 7 dead? Please give me options to charge/turn on

Good evening everyone, I have a Nexus 7 8gb, but the thing is, I cannot turn it on now.
It happened as follows:
I was using it every now and then, mostly to read and play.
I was using the charger to charge my cellphone too (XTC Explorer) as it was a lot faster, being 2amp/h.
I updated the cell to 4.1 and at the same week noted the battery wasn't running that long, but blamed it to the rom.
The cellphone also took a lot longer to charge with the nexus charger, yet again I blamed the rom.
I noticed the Nex was at 8% while reading so decided to charge it, but I guess I forgotten.
The next time I wanted to use it it wouldn't turn on. I figure it had no battery.
I plugged the nexus charger to the nexus a whole night and in the morning it still wouldn't turn on.
I figured something must be wrong with the charger, so I tried with the cellphone and nook color charger, but both are .5 amps/hour.
It wouldn't charge, neither connected to the pc (also .5a/h via usb) so I tried a psp go charger, as it is rated at 1.5 amp/hour, much closer.
I connected it at night and saw the charging icon (white on black battery with the ray) and left it overnight.
The next morning it wouldn't turn on either.
I've bought it almost two months ago and I really enjoy it =) but now I'm desperate.
I cannot call google play for the warrant because I'm in Argentina, and I don't believe they will ship me a replacement, nor anything. This one my brother bought from them, but he went back to US a few days ago, and I didn't think of giving it to him to RMA.
I tried keeping the on button, for 5 secs, 30 sec, 90 secs, 120 secs, and no dice. Also tried holding the Up Volume key to restart it, but no chance.
Please help!

Had a similar issue to this over the weekend after not charging for 2 days and the battery going dead. I let it sit on the original charger overnight and for some reason it did not charge. It kept booting and shutting down once it booted due to a low battery warning. It eventually got to the point where the screen would go to fuzzy lines and light but no boot.
To finally get it working I did a combination of a few things but don't actually know what got it going.
Put it on a different (kindle) charger and let it sit for an hour or 2, did several hard resets holding both just the power and also the up/down volume and power all at the same time for up to 60 plus seconds. I switched back to the stock charger and did an additional hard boot by holding just the power for 30+ seconds and it started booting and charging.
I did however put it on the charge again last night and noticed this morning it was still at half battery and didn't get a charge. I ended up putting it on a mifi charger this morning and it's charging again so don't know what is up with the stock charger. Also, have all the latest updates to 4.2 as far as I know as there have been charging issues reported with earlier versions...

Try this, it just saved my device:

try holding down the volume DOWN and the power key for 10 seconds, then release the power key and keep the volume down key pressed, and it will force the unit to restart into the bootloader from any stage, its effectively like pushing the restart button on the front of a computer and constantly pressing the delete key to get into the bios.

[Q] HTC One (M7) Dual Sim, no boot after reset

Never dropped, never rooted etc, normal phone. The phone was purchased 9 months ago and after around 6 months exhibited some lags for menu/loading keyboard etc. I carried on until today where things got so bad with menu/program lag and so on that I decided to reset. I backed up everything from phone memory. From 32 GB internal memory around 12-15 GB were free. Battery was around 50%. I went to menu and made a factory reset.
After awhile, phone shuts down and does not turn on. When I connected the power it showed the battery charging icon and the orange light went on but no animation (if any) on the charge icon on screen.
Followed the steps online to hold power and volume up and it finally shut down. Now does not turn on at all.
Following the directions from this page on xda-developers , option 1 does not work at all. Option 2 makes a short vibration after initial 15 second but orange charge light does not illuminate. Continueing on holding the buttons makes short vibrations every 13 seconds onwards. Also holding power button and volume up does exactly the same thing. Power and volume down does not do anything.
Please help ! What did I do wrong ?
From XDA-Developers:
Option 1) Hold Volume Up & Down, then hold power for 90 seconds. Should vibrate/flash/respond somehow. Sometimes
takes some time and a few tries with long waits in between.
Option 2) Hold phone up to bright light (headlight or lamp bulb) and hold power for 15 seconds. Orange charge light
will illuminate. Play with power & volume buttons till it boots.

[Q] Dying at 17% battery

My Nexus 6 is dying at around 17% battery. I've tried using battery calibration apps to fix it but they haven't worked. I've also factory reset, and went from LMY47D to LMY47M, both of which would die at 17%. Any suggestions?

What you mean by die at 17%?
Does it shutdown automatically at 17%, and you can't turn on by pressing power menu. Right?
Then how you overcome from this situation? By charging your device again?

I had a similar issue. This helped:
1. Power off your phone.
2. Press and hold the Power and Volume Down buttons. This will put the phone in fastboot.
3. Use the Volume buttons to scroll through the menu until you see "Bootloader logs"
4. Press and hold the power key for a long time (7+ seconds) until the phone reboots.

The phone shuts down at 17% and when I try to turn it back on, it shows the battery dead icon and won't turn on. After charging it for about 30 seconds it'll turn back on and say it has about 18% battery.

Unfortunately, this did not work. Phone died at 15%, about 10 seconds after it prompted me to turn on power saving mode .

It seemed to work for me. Phone drained to 5% and automatically shut down. Charged it to full without booting, so if it still behaves, it fixed me.
How did you discover this "fix"?

I can't remember, sorry. It was whether here on xda or on google forums.
For me this issue started after I used my (original) Nexus 5 Qi charger with my N6. Almost the same problem as you described but on my N6 it was 17 %. Tried the workaround mentioned above, sold my N5 with the Qi charger and the problem disappeared. It's been a while now. Guess 2 months...

I tried this again, this time holding the power button until "Google" appeared on the screen (The first time I let go when the screen turned off) and it seems to have worked! I'm on the second cycle now and the phone reached 0% the first time and I'm at 12% now.

Good news! Hopefully this will last.
Btw: do you use the original turbo charger or a qi station?

when i scrolled to "bootloader log" i pressed and held the power button for some seconds and it turned off and it wouldn't go back on until i released it and pressed again.
how exactly did you do it if I may ask? thanks

I held the button for probably 10 seconds. The screen turned off for a few seconds, then Google appeared and I let go of the button

thanks, i know the trick now. I had to scroll to bootloader log, press power once, then long press the power button for reboot. it'll turn off the phone if i did not press power once, i think.
that's what happened to me.

I have the same problem though my phone powers down at varying percents (15-60%) all well above the level where the batter should be expiring. I Googled and found a number of suggestions. None worked including the "Bootloader Logs". My phone will power down 2-3 times a day. Finally called Google and asked for a replacement.

Stop using the Qi charger for a while and retry the workaround. Don't charge your phone with a Qi station for the next few days - just to verify whether Qi is causing your problem or not.

I may not make it much farther than the end of the week testing since I RMA'd this back to Google.
Can verify I charged overnight on the included charger.
I have had two power downs so far today.
These however did not require me to plug into power in order to turn the device back on.

Did a complete system wipe. Within two hours the phone completely powered off on its own (about 37% power displayed). Set the phone up as new -- did not restore prior apps. Replacement is on the way.

FYI:
Last weekend I accidentally charged my N6 with my friends charger. Guess what happened? My phone started to randomly shut down. I went through the workaround steps again and fully charged my N6 with the original turbo charger and - surprise, surprise - no more shutdowns.

I don't have the link, but I found a google support thread on this issue. The bootloader trick apparently clears the battery stats.
I am guessing that some 6's don't play well with non-stock chargers and that causes reading issues, leading to over charging and battery life messed up, my phone was fine, then it started acting up again. I haven't seen a permanent fix for this and plan to RMA my phone.

Question I think my 5a is dead. Any tips/ideas?

Sitting here in my hotel in Houston with what seems to be a dead phone. I have a stock ROM, rooted 5a that froze while I was waiting to de-board my plane and went black. Forcing a restart by holding the power button hasn't help. The phone is on the charger and holding the power button while plug in hasn't helped either. The phone had a charge so it can't be the battery. The screen just froze while an app was starting and it went black. Any ideas how to get it to restart or should I consider it gone? Appreciate any feedback.

It could certainly be a battery failure.
Is showing a full charge?
Or is the charging screen dead too?
I'm not familiar with Pixels but if the battery can't sink enough current it won't boot.
Try the boot menu; it uses less current.
Otherwise it could be a loose cable, dead display or mobo.

try a hard reset
hold down power + vol up + vol down all at the same time for about 30 seconds. wait about 10 seconds then try to power it on again. does not wipe anything. just forces the phone to turn off. if it is locked up in a power on state that should force it to power off. provided there is not something more wrong. like a blown board or battery failure.
if the battery was extremely dead. 1 to 5% you can try to trickle charge it by plugging it into a computer usb port. the rapid chargers they include with phones are only for maintaining a charged battery. i had to do this with an ASUS tablet i had that got below 3% and would not take a charge from the supplied charger. this is what their support told me to do. i was surprised that it actually worked bring the battery back to life.

Kinda been in the same boat before(definitely my fault tho).... When sending quick ADB commands, restarts, etc., either my ASUS laptop goes dark for 5-20min or sometimes even my 5a will do it but not sure why.
Agree with everything rchris494 posted. My 2 cents & what helps me usually is using the system that didnt go dark on me to halfass "jump start" the other(not likely but its almost like a command is hanging for me)....i.e. restarting my laptop while plugging in USB to 5a when laptop powers.
It's kinda Super Nintendo take out game cartridge, blow as hard as you can, ram back in while perfectly hitting power at same time logic that inexplicably works. Worst case, Pixel 6a pre-order start 07/21, good luck & keep me posted.
