[Q] [HELP!] Phone won't turn on after pressing "power down" option

greetings to all XDA members
I could not turn on my phone after accidentally selecting the "power down" button in bootloader after pressing down power + volume down
What did i just do? How can i turn on my phone now??? HELP ME! T_T

Pressing the "Power down" option in HBOOT should not be a problem. I've done it a couple times on purpose.
Did you try a long press of the power button, maybe 1-2 seconds? Is the battery sufficiently charged? It will charge when powered down.

be4 i clicked power down, it was around 30% battery (maybe that's why) and since the power-down thing, even if i plug in to charge there is no orange/green light on the LED, is it still charging even without the orange LED lighting up?

There is a known bug with one series. This is a Hard Brick, sorry its true. HTC agreed to fix mine and its being sent back 2morrow. however JTAG CANNOT Fix this issue. i have tryed MANY things and Nothing helped. it completly ****s the main board. Htc have said that this issue is being looked at and for me to NOT press and hold the volume buttons with the power button again, They have said it is a hardware problem not software problem. This issue cannot be resolved by a update only fixable with hardware change.
Please goto this thread for help http://forum.xda-developers.com/showthread.php?t=1729847

Dude, not again... Did you get QHSUSB_DLOAD? If you did. I'm sure it's a hard brick. It happened to me once. The only solution is phone replacement. Take your phone to your seller. You will get a replacement phone within 3 working days.

Phone just stopped turning on..

well...this kinda ruined my night yesterday...I went to a concert yesterday around 8 and my phone had 70% and I was checking facebook or something like that and without no notification or warning it froze and turned off on me. I figured it was a normal freeze..and I attempted to turn it back on and nothing happened. Went to my car to try to charge it and nothing. Not even a charging light. A day has passed after the concert was over (could not take pictures, thanks htc..) and now the "dead battery symbol" comes up and the orange light keeps BLINKING..to my understanding it means that it is not charging? What could it be..anybody could help me out .maybe a soft reset? no charging it for a couple of minutes?
Anything would help. Thanks

Try pressing and holding power and volume up?

I'm sure you've already tried that, but can you confirm that you have left it plugged in atleast for 5 hours continuously after this happened.

And hold the power and volume buttons down in a well lit environment, there's a "pocket check".

You can also try by hold the power and volume buttons UP

Thanks for the replies , i have tried those opctions. Holding the power and volume UP and thencanother try wih the DOWN the with both. It just blinks orange now. I just woke up and plugged it in again, am going to work and going to leave it like that, hopefully that does the trick. Should i call htc ? It hasnt even been a month since the phones came out.. I did not do anything to "kill" the battery

Ofcourse you may call Htc.

the same happened to me now.did u find a solution?????

Have you got delvolper options enabled, if so when connected to your computer you could try Adb reboot or Adb reboot bootloader

Well only thing I can suggest is you leave it on charge over night. Then try & power it on if no go try and hold the volume up and power button while plugged in for at least a minute if that Dosent work take it back where you got it from.

Unplug phone. Hold vol up and power for 10 seconds, let go, try to power on phone.

Hard reset fastboot is enabled

Hello everyone, my girlfriend is having an issue where her m8 won't turn on. We looked at it last night and put it on the charger (although we didn't expect it would be dead already) and then left it over night. Woke up this morning and it's still having the same issue. I tried doing both a hard reset and soft reset, just anything to get it out of this weird loop it's in. Everywhere I look for information on hard resetting it says you need to disable fastboot - something a little difficult to do if your phone won't turn on. Are there any other tricks or work arounds that maybe I'm overlooking? I'd prefer to stay away from 3rd party fixes if possible that will void the warranty as I don't want her phone to get rejected if we need to send it out for repair. The closest repair facility is a bit of a distance so I want to see if there is something we can do from home first.
Thanks!

Disabling the "fastboot" option isn't really necessary.
Although I'm not sure what "weird loop" means. If its actually doing a boot loop, and rebooting, then just hold vol down to enter bootloader.
Otherwise, if its just "stuck" on the boot screen, then hold power and vol up to force a reboot (hold for maybe 10 seconds or so); and the moment the screen goes dark, let go of vol down and start holding vol down and don't let go until you see bootloader.

My apologies, my terminology may be incorrect.
The display is not turning on. Holding power + volume up or power + volume down do not get the screen to turn on.
The instructions I looked at all say disable fastbooting before trying to force boot or hard reset. So that was my confusion.
I really appreciate the help.

Any charging LED when charger connected? Any response from computer if you connect the phone?
Leave the phone on charger (wall charger, not connected to a computer) overnight, and try the button combos again (also, try just holding power down, no other buttons; in addition to the button combos you listed). Try this with the charger connected, as well as without.
Some folks have gotten their seemingly dead M8's to revive with apparently random combinations of button pressing (often holding the buttons for a long time, 1 to 2 minutes) charger plugged in, etc.

The only reasons instruction say that, is that the phone either needs to be "real" power off, or a reboot in order for the button combo to go into bootloader (power + vol down) to work. When "fastboot" is selected in Power settings, it actually prevents a real power down (its actually just a sleep state). But if you reboot, it doesn't matter. A reboot is a reboot, it doesn't matter if "fastboot" is enabled. And Power + vol up is one way to force a reboot.
None of this matters, if the phone is not responding (screen not coming on) at all in the first place.

I did leave it on the wall charger last night and was playing with different combinations. I'm going to try plugging it into my computer when I get home. I'm not noticing any LEDs come on however which is what is making me think it's not a screen issue.

I recall reading that someone got a similar issue sorted by hold Volume Up or Volume Down + Power button while holding the phone under a bright light(proximity sensor at the front needs to be directly under light).
There was similar threads/methods on the old HTC One(M7) too that apparently worked. Don't know if it's just coincidence or what Might be worth a shot.
Edit: Volume UP OR Volume down, not both at the same time

Have you tried holding Power and Vol Up button when the phone is pluged in?
Tri taking SD Card and SIM card out and start.
Have you tried another charger?

[Q] Galaxy Tab S - LED Flashing - Won't turn on

Hi, was wondering if anyone else has/had similar issues?
Got the Galaxy Tab S today and was spending time setting it up. Connected to the PC and charge was at about 57%. Suddenly the window displaying tablet contents on the PC disappeared and the screen went black.
The power button didn't turn the screen back on. I held it down, thinking that it required a hard reset but nothing happened. I disconnected the tablet from my pc and went to use it's dedicated charger. The battery icon came up, stating it was 57% charge, and shortly after the LED light on the back of the tablet started flashing rapidly. I quickly took out the cable.
I've tried holding down the home key, volume down, and power button and nothing happens. I then tried the same and having a finger on the screen. Then I repeated the process again with the cable connected to the charger, and then computer.
No matter what I try, the device won't turn on and the LED keeps flashing repeatedly when connected with usb charging cable. I also tried using another cable.
I'm thinking of phoning up where I got it from tomorrow and asking for a replacement, unless there's something I'm missing here?
Any thoughts would be great, thanks.

My guess would be, you are not pressing the buttons correctly.

You try just Power+Vol Down?

I tried that just now. Nothing happens.

How about pressing power, vol up and down, home huttons at the same time for 1 minute

That doesn't work either. The only response I get from the tablet is by plugging in the charging cable and then it goes on to display an epileptic inducing light show with the LED constantly flashing on and off

Never seen this problem before. Could be a bad partition making it not boot. Replacement may be your answer as its better to get a new one and be safe.

I've used various tablets before and never encountered any of them not booting at all. The led flashing business is very weird. I'll phone up the store I got it from and ask if I can get a replacement.
Thanks for the responses

Tablet won't turn on / charge

Hi,
I've only had my Samsung Galaxy Tab S for a few weeks. Whilst on a plane the battery went to 0%.. no problem I thought as I'd simply charge it when I got to a power source.
However, when plugged in, nothing happens. No LED light, nothing on the screen. I've plugged it into a wall socket and via USB into a PC. I have held down the power button, home and volume down for a period of time, as well as just the power button and volume down.
Has my tablet gone kaput?
Cheers,
Titanium

I'd just let it charge for a while. It'll take a bit before it comes back to life if it was completely drained.
If you still don't get any response hold POWER + VOL DOWN.

Should it show any lights? It's as if it's not even charging at all.

If it was powered off I'd expect the battery icon to show.

Yeah, tried to hold it down. No LED lights and nothing shows on the tablet. It's as if it's just dead.

There are no leds.
I know someone else had the same problem. They used a different charger and it worked.
Try that first.

I had this problem.
You'll have to pry off the back cover, remove the wire that connects the battery to the motherboard. (A battery pull, basically).
Keep it off for 30 seconds. Then plug back in.
Use ifixit for details about opening. Feel free to ask for more help.

Try this one.
1) connect the tab to PC
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.
John.

Now there are a few things you can try...
First check your charging port for any dust or any foreign particle. There has to be a small gap between the base of the charging port, and the small slab above it. Carefully, using a board pin, try and push that slab a bit up, don't apply too much pressure, just enough to make it move slightly!
This can happen sometimes if you drop your phone.
Next, make sure your charger, and the USB cable are working fine.
Also tell me if you have any Xposed module for your battery installed on your phone!

Thanks so much for that.
This morning, I plugged my tablet in to AC charge before leaving for the day -- battery was at ~30% and all was well. This evening, I came home and the tab was stuck at a weird Samsung logo -- not the normal boot with colored ovals, but the logo surrounded by a moving star field, never seen before, and could not get the tab to respond, turn off, do anything. Tried many wacky suggestions found on the intertubes to stop/start it, including holding power plus touching the screen for > 30 seconds, none of which worked. Never would have thought your suggestion for download mode would work, but it did on the very first try.
I'd like to know how the tab got into that state, and what that star field logo is about. But at least it's working again, for now.
Thank you.

That's the normal lollipop boot screen.
