[Q] Help Needed : Can't turn on?

My Transformer was working fine, battery fell below 9% so I put it to sleep and plugged it in...
Now the device will not turn on, back of unit is getting warm?

Well, the warmth will be the battery charging. No issue there.
See one of the half dozen threads about not turning back on.

It came back to life, after holding the power button still seemed dead, then i plugged in a HDMI cable and it turned on.

My power button is finicky... every thing else seems perfect...

Mine does this. You have to power off completely. To do that, you must hold the power button for more than 10 seconds to turn it off. Wait a bit, then power it back on by holding the power for 5 seconds.
I've searched around and people say it's the lock screen that causes the screen to blank. But I don't think that was it, I disabled it and it still does it.
Next someone says it has something to do with WiFi, I don't think this is right also because it has happened at times when I had the wifi OFF.

Are you saying before charging you power it off completely or always?

No I'm saying to do that when your screen is blank and can't turn on

HELP!!! Battery died yesterday and phone won't turn backon!

Last night I ran my battery down to the point where it said Powering Off or whatever. I charged it all night and nothing. When I plug it in, sometimes it has a red LED in the upper left for a econd or two, then does one vibrate, then becomes completely unresponsive.
I've tried a battery pull and hooking it up that way. Same thing - red LED, one vibrate, then nothing. Some times when it is plugged in, it will show a battery picture with no juice for just a second then it all goes blank again.
I am running AOKP build 4 with Slim Kernel.
HELP!!!!!!!!!

I would try another battery, sounds like the one that you have us showing up as dead even after charging overnight.

Just unplug the phone... pull the battery... put the battery back in and WITHOUT plugging the phone in turn the phone back on (may have to hold the power button for a little while).

Strange plugging in the phone without a battery should bring up the charging screen with a question mark in it I think

So the problem has been remedied, though I would like a little input to better document this problem and solution...
I took the battery out, plugged the phone in, then popped the battery in. Really quickly, I got it to enter the weird screen where it is an exclamation point in a yield sign (I forget what combination of buttons I pushed to get here). It said Volume up to continue or Volume down to do something else. This is where it was fuzzy because I was freaking out about having to buy another phone.
Anyways, I hit the volume button that was supposed to reboot and it went through the boot sequence and showed me charging at 98%. This is strange because it was plugged in all night but non-responsive - not power, no heat, no nothing.
So long story short, if running this ROM/Kernel combo - DO NOT LET THIS THING GO TO 0%!!!
And if anyone can tell me what combo I pressed to enter that screen, it would be very helpful. Thanks guys!

The screen you got to is called Download Mode..
Download Mode - This is a setting in which you will put your phone when using Odin. There are other ways, but most people will reach download mode by powering down, removing the battery, and holding volume down while plugging the factory usb cord into the computer and phone. Odin can only communicate properly with your phone if the phone is in download mode.
For future reference you have to
1. hold volume down + power + home button
2. Per on screen instructions, press volume down to reboot/restart device.
This is a documented problem and one that has been posted about numerous times, glad you figured it out. Also, this will always fix the problem so you should not worry if the phone running this ROM/Kernel combo runs down to 0%.

too bad samsung doesn't have a genius bar.....lol

[Q] nexus 5 red light

hi guys,
2 days ago I got a nexus 5 loved it until today I was playing a game (asphalt 8) and it just turned it self off don't know why just did now all im getting is a flashing red light I was on holiday with the phone could the plane have done something to it anyway guys please help me
thanks
Prime

No, the plane didn't do anything to the phone.
Did the battery die? Did you stick the phone on a charger after it turned off?

Best guess is that it's overheated to the thermal shutdown limit.
Leave it a while then try powering it back on

na, when you hit the safety shutdown temp, all it does is shut down, you can boot it right after. ive reached it many times(on purpose), it works.
what the op is describing sounds like the rlod on the nexus 4(red light of death). it happens when the phone thinks it went below 0%. on the n4 there are two solutions, one works sometimes, the other all the time. the one that works sometimes is leave it on the charger for several hours, then try to boot into the bootloader, then shut off the phone from there and keep charging. the method that works 100% is to remove the back cover, disconnect the battery, then reconnect it. this is a hard reset for the battery, and works 100% of the time on the nexus 4.

if it was something that happened on its own(without you tinkering with your phone), then yes.

You may want to give this procedure a try, its copied directly from Google's product support page for the Nexus 7.
Make sure there isn’t any dust or lint in the power port.
Using the original power adapter and USB cable, plug your Nexus 7 into a functioning power outlet. Nexus 7 has specific power requirements, and the USB cable and power adapter that are included are designed to meet those requirements.
Ensure the power cord is securely connected to the tablet and the power adapter.
After 1 minute, check to see if a battery icon appears on the screen.
If the battery icon appears, press & hold the Power button for 15 to 30 seconds to see if the device turns on.
If the battery icon doesn't appear, try accessing the Android bootloader menu:
Press & hold the Volume down button. While holding Volume down, press & hold the Power button for at least 10 seconds until you see an Android robot and the word Start on the screen.
Press the Volume down button until Power off is highlighted. Press the Power button to select that option.
Disconnect the charger and reconnect it within 10 seconds. A battery icon should appear on your screen.
Once the battery icon appears on the screen, allow your tablet to charge for at least 1 hour before turning it back on.

I got a new one thanks for all your help

I just had a red blinking light and no charge indicator situation, as well. Nothing seemed to work: plugged it in for 20 minutes, unplugged it for 20 minutes, plugged it back in...and after another hour on the charger I finally noticed the blinking red light had gone away, and hitting power brought up the charging indicator as normal. Booted right up and has been fine since.

My Nexus 5 just started doing this. I was in the middle of playing a game while my phone was on the charger (Brave Frontier) and suddenly the screen went dead and I had the red flashing light. I'm guessing I was using the juice faster than the charger could fill it so I killed it. I couldn't get the battery indicator to come back but as I was typing this the red light finally stopped flashing and the phone rebooted.

This happened to my N5 today. I was on a Hangouts video chat while plugged in from wall charger and I noticed the battery was actually draining rather than charging. So I figured hangouts was discharging the battery faster than the charging. Eventually it went to 0% and stayed that way for a while and suddenly the screen went off and the LED started blinking red. Followed the steps posted here, plugged in, left for a while and the blinking stops and phone boots up.
Never Hangout-ing with low charge ever! D:

Zenfone will not charge and turn on. All it does is buzzes every 1 and a half minute

I bought my Zenfone 2 about 3 months ago and it had been working perfectly fine. However, on the day before yesterday the phone appeared to lag more than it usually does but I didn't pay much attention to it. Later in the evening I noticed that the battery was not reducing and it remained constantly at 50%, despite me having watched at least an hour of youtube on it.
Later, when I was watching some videos online, the phone suddenly turned off - I thought that was because I had used up all the battery, so I plugged it into the main using the original cable and charger, but the phone would not charge and the little light on the top right of the phone never came on. I could not turn on my phone and all the phone would do was buzzes every few minutes. So since then, I have kept the phone connected to the charger (and it carried on to buzz twice every few minutes). I tried to turn the phone on yesterday morning by long pressing the button on the top of the phone but it would again not turn on at all.
When the phone is being charged, it buzzes every 1 and a half minute regardless of which charger or cable I'm using, and when the phone is not being charged, it doesn't buzz
Someone tried to help and suggested me to do the 3 following things:
1) Hold the power button for 15 minutes then let go and press for another few secs to try to turn the phone on - I did this, and the phone did buzz when i tried to turn it on, but the screen is still off, as well as the small light on the top right
2) hold the volume up + power button for 5 seconds, then release volume up before releasing power button - my phone buzzed after holding both volume up + power button for a few seconds, but still the screen did not come on and neither did the small light.
3) hold the volume down + power button for 5 seconds, then release volume down before releasing power button - nothing happened. The phone didn't even buzz.
I don't really understand why I was asked to do them, but i did them anyway
I am currently in the UK and I bought my phone from abroad so I cannot get a warranty fix in the UK.
Please kindly help if you know the the problem is and please give me some advice.
Much appreciated. Thank you.

Bootloop + Power Menu problem

So today i started having bootloops, it was showing the Powered by Android screen for 2 seconds then booting again over and over for few hours
Now after it somehow got fixed by itself, i managed to turn the phone ON and to clear Cache
So far there are not bootloops anymore
BUT
huge BUT
the phone is poping the Power Menu most of the time, and then every touch on the screen just "presses" on the Shut Down option
If i press on the Power button myself it shut him down automatically ...
EDIT:
Would like to add, that i never unlocked it, it's the regular OTA version.
I doubt a wipe wll help, but i really wont mind if thats the case
Its almost like something pressing the Power button sometimes, but even WITHOUT the back case it still pops that power menu. even if no one is touching it at all it still pops it once in a while, which cause shut downs once in a while ...

So i woke up
The phone is off, i cant turn it on
I charge it for few hours already and still nothing happens the power button doesnt do nothing, it doesnt vibrate
So i connect it to my PC, it shows it as a Marshal something in the device manager but it KEEPS disconnecting and reconnecting every 2 seconds
I have found a "fix ur bricked phone" threads but they all using a tool that needs the phone connected to the PC, well my phone cant stay connected more than 5 seconds for some reason [ different cables, different computers] it keeps on popping in and out

Did you drop your phone in the water or something? Wet or damp from the rain maybe?
And did you try connecting it while in fastboot or recovery mode?

Maybe wet from Humidity but thats all
i cant reach fastboot nor recovery
as now it all black, not turning on not even for a bootloop
This problem happen when the phone is getting wet ? its certainly didn't but maybe i should "fix" it as a wet phone should be fixed? should i open it and dry it out? maybe take the battery out? its not that easy to take it out tho

I had a phone which was wet from the rain, it made the power button faulty. It would randomly turn screen on off like in your case. I took it to the repair shop and they cleaned the insides and it was fine again. If you're sure it's not the rain or anything then maybe that's not the reason, just a guess.
How about plugging in the charger? Does it light up? If it lit up and you cant turn it on after maybe its the power button problem.

plugging the charger doesnt do nothing
Although i got a portable charger with a led , the led turns on when i plug the One, BUT, the led bar doesnt decrease even after few hours, so its like "trying" to charge but not charging anything

Try this from OnePlus Customer Support:
2. Power cycle the One by holding the Power button for 20 seconds 5 times.
3. Attempt to start the phone by holding down the Power button along with the Volume down button to start recovery mode and performing a factory reset.

or hold Power button with the Volumn up button to see if you can get into fastboot mode.

lol bro... seriously.. you really think i didnt try that stuff before opening a thread?
I already scanned the entire web and no one with the same issue have posted a fix thread
one plus doesnt even care about their customers

Is this the guide you said you saw? http://forum.xda-developers.com/oneplus-one/general/guide-unbrick-oneplus-one-t3013732
Why not give it a try? Follow the steps and see if you are able to unbrick your phone.

I mean there's not much you can do if you can't even turn on your device in the first place :/
