[Q] Phone wont boot

I have a xt925. The phone is not mine, I got it off of somebody for a few days. He told me the phone would not charge or turn on.
Phone was never rooted or anything like that. Anyway the problem is that the phone will not turn on.
First thing I did was charge it for a few hours. The green light DOES come on. When I try to turn it on it does not boot up and the green light goes away. I've also tried to boot into recovery which does not work.
tried the following:
-holding power button for 30 second
-holding power and vol down for 30 seconds
-holding power and volume up + down for 30 seconds
-plugging into the computer (computer does not read it)
What else can I try to get this thing to turn on???
Thanks

Battery is very low ... wait a night ... the green led will shutdown and the phone start automatically...

[Completed] [Q] Moto G (U.S Cellular) boot loop. wont charge.

ok so i have a moto g that is fully stock and all my apps were from the playstore and i never noticed any bad lag at all. but one day, out of the blue, i wake up to my phone showing the blue m logo and then a black screen and repeat.
so i tinkered around with it and searched the internet and heres what i found out:
I can get into fastboot mode but cant use any tools except for the barcode tool otherwise the phone just goes back into its boot loop. (yes i selected with the volume up key)
the phone has no power what so ever unless its plugged in. and i dont have to press anything to start the loop, it starts on its own as soon as i plug it in. the led blinks white twice and shows the m logo for about 5 seconds then a black screen and repeats once more then it is black for about 5 minutes then its goes into the loop once more.
i cant flash the stock firmware because when i plug the phone into my computer and put it in fastboot mode, the fastboot menu pops up for a mere seconds then the screen goes black and goes into the loop again.
the phone is not damaged and worked with no problems a few days back. i have been through countless websites!
any ideas?

Hi,
Can you specify if it's a 2013 or 2014 moto X.... And I will have your thread moved to your device Q&A section.
Sounds like a stuck power button to me though.
Thanks!

Phone won't turn on

Hello guys, I have D6603 and tonight, phone gone dead... How it's happened... So, I was playing on phone and put phone in my pocket and stand up and phone felt from pocket and no reaction. I was thinking that display is broken.. but when try to make something, no reaction. I put it on charger (before drop it has 89% battery) and red light appear. I told WHY!? you have battery... after 10-15 sec, display light up and shows SONY, I told great, display is OK, but 1-2 sec after SONY logo, phone restart. NO VIBRATION, NO START UP, NOTHING.... when SONY logo disappear, red light gone for 5 sec, and then light up bright, after 10-15 sec red light dim and SONY logo appear, this is for 1 min and it stops, only red light... I left phone on charger, after about 30 minutes, red light turn off and nothing, phone won't turn on. I try Vol UP + power, yellow button, remove battery(when battery is not connect, it appear empty battery logo and 5 sec later phone restart, when connect battery again SONY logo for 2 sec and restart),nothing, no vibration... I try connect with PC, only fastboot work...

do the 20second reset. this simulates a battery pull.
i dropped my Z3 too, no damage at all, but it doesn't work at all anymore. No red lights nothing.

Dead phone, red charging light & start up screen loop after dropping it

After dropping my XZ on a table, it just went completly dead. The device switched off and wouldn't start again. So I tried to charge it, and hoped for the best, but when I connect it to a charger something strange occurs. The small red charging light comes on, and the black "SONY" text on a white background shows for a few seconds, then the device shuts off and the red light disappears. And from there on it just loops from black screen to red light -> sony logo -> black screen no red light -> red light -> sony logo -> black screen no red light and so on.
I've tried 2 different chargers (for several hours), tried starting it holding vol up and also starting it holding vol down. Tried connecting it to a computer with the xperia companion software, but it doesn't show any signs of connection. The SD card is removed.
I assume it has to be some kind of hardware issue (relating to the drop, yes i was drunk). But does anybody have experience from this problem and might advise what part is broken?

LG Q6 boot problem

Hi,
i have LG Q6, at the time it wont turn it on. When i turn on vibrates and show logo for 1/2 secund, than black and vibrate again in 10 sekunds. Than is black and again vibrate maybe on 20sec or 30sec.
If i plug in charger on vibrates once, than black and again like if i turn it on. I think that was dead battery and i replace it and same problem.
I hold voluime dome and power on to go in hard reset menu and if i choose yes, and one more time yes then phone turn off.
If i go in download mode i only see for 1/4 seconds ' download mode and than goes black and vibrates once.
if i go in safe mode pwr, after logo vol down - nothins happend, when turn on i just see logo for one second and than black, i press vol down when see logo but go black and vibrate once and thats all :/
What to do ?

Battery ded
It sounds like a damaged battery. Try changing it or leave it charging for a while. if it does not react then the battery has definitely died
Edit: I had not understood the part of the changed battery. You took it with a good technician or it just made him "like I change him"
