My MyTouch 4G powered off one day and won't power on anymore. I've tried pressing the volume down and powering up at the same time, but no response from that. I've checked and made sure that the buttons are fully functional. When I plug the phone in to charge it or to connect it to the computer, the back, Flash LED lights up. Help please?
I've tried looking for other posts and seeing if anyone has had problems like I'm having and there seems to be no one else. Thats why I'm making this post. Anyone know how I might be able to fix this?
The phone was running the stock MT4G OS. I tried establishing adb connection but nothing happened.
Thank You!
Your power button might be dead.
Or you have a brick

So, the phone's dead now? There's nothing I can do about it?
Connect to charger, then put the battery in.
Try several time.
If it's power button failure - this might bring it to life.
If not - there's nothing you can do, give it to someone to fix.

very curious to know if this worked...
I have a question that I've searched for, and can't find an answer to.
I've been reading about this red LED business (an unresponsive N4 that doesn't respond to a hard reset but flashes a red LED when USB is attached). Some people have gotten their phone to function again by:
1. Charging it normally
2. Unrooting it to stock with Wug's toolkit
3. Doing Faux's method of button presses
But quite a few people have indicated that NOTHING worked. They've had to get a replacement device from Google.
Maybe some people bricked their N4 without the red LED, or otherwise got an SOD that responded to nothing.
So here's my question:
Has anyone actually pulled the battery on their N4? In other words, open up the case (there's info how to exactly do that all over the web) and disconnect the battery as the ultimate hard reset? Did it work after that? What's been your experience...?

That is a youtube showing the disassembly of the Nexus 4 including the battery removal.
Thanks for the link.
Permit me to clarify my question :
Has anyone pulled their battery on the N4 to reset their device (probably as a last ditch attempt to revive it)?

Pulling the battery is not necessary. Holding the power button down for 5 seconds will cause a hard power-off and is exactly what a battery pull would do.

With all due respect, that's not exactly the same thing as a battery pull. Pulling out the power source physically guarantees the incompletion of an electrical circuit. Which might be necessary to fully reset a malfunctioning device.
That's why I started this thread: I'm sure a lot of us have done a battery pull on other phones with user-replaceable batteries, like a GNex or S3 or even prior generations, to reset a borked device. But has any among us done this with a Nexus 4 to try and revive it?

You obviously have very little knowledge about how electrical circuits work. When was the last time that holding the power button down on your PC failed to shut it off? It's programmed at the hardware level. So, like I said: a battery pull isn't necessary. Also, we have this thread already. Try searching next time before making a redundant thread.

Thanks for your kind and considerate reply. I already read the thread you linked, and found it insufficient. In fact, even this thread with multiple links did not answer the question I originally posed: Has anyone tried to do a hard reset via battery pull in the N4?
As for your gracious comment about my knowledge of electrical circuits, I will be the first to admit that I am not an electrical or computer engineer. However, I have worked in IT a little bit, and there have been multiple times when holding down the power button on a hung PC with a BSOD simply has not worked. We literally had to pull the (power) plug or battery to begin the troubleshooting process. As such, your analogy does not give me comfort.
So you say a battery pull is not necessary? Tell that to the fine people who've tried everything (but maybe not a battery pull) with a red LED and ended up having to use an RMA. Are you willing to bet the life of your firstborn that "holding down the power button" is absolutely equivalent as yanking the battery? If so, I wish I had your sense of absolute certainty. Maybe you're right, but there's only one way to tell,
So let me hear from people who have actually tried it.
I have been working on computers for over 10 years and not once did I have to remove the cable. ALWAYS the power/reset button worked. You don't know how they work do you? You ever put together a PC? Hooked up the power/reset to the buttons on the case? Ever use a screw driver to turn one on? You would know all of this if you have. Power/reset always work by design.

Pushing a button to shut off is not the same as pulling the cable. Every semi descent IT/electrician should know that. In real life practise you can check it for yourself: pull the cable from you PC and push the power button aftrewards, you will see the LED will flash or even the fans will rotate. Its basically the first step to fix some "hang, freezed, etc." issues.
On topic: nope i did not disconnect the N4 battery
what if the pc didn't boot up?
you obviously would disconect the power before servicing a unit.
holding the power button isn't the same as disconnecting the battery you wouldn't check the phone or pc when its still connected to a power source, todays pc still have 5 volts standby so its not a hard off and can be triggered remotely that's why disconnection is the last resort.
then checking the battery,current and charging it via other means before determining its a faulty unit as a whole.
any other phone you would, as the battery wears over time and most probably isn't covered by warranty.
I haven't opened my unit, ask me in 11 months,

Now we're talking! Tell me how a screw driver turns on power... That's a mechanical switch, right? But a button that has more than one function must necessarily be more complex than on/off. This is the hardwired programming that was previously mentioned. Can this ever be borked by a software-driven event?
What if an overclocked kernel being taken to its limits by benchmarking software exceeds the safe power draw of the battery, causing all kinds of random damage in circuitry (maybe even the button's?) Is it conceivable that as long there is a power source, that damage would be ongoing? Therefore, isn't this somewhat analogous to exposing a phone to water, wherein the very first thing everyone recommends is to do what? Pull the battery. Or in the case of the N4, hold the power button for 10 seconds...
As for fixing computers, if something is going wonky and it might have something to do with the power supply (beyond a BSOD) possibly starting to short, I do think someone as experienced as Eric would also be pulling the plug, not sitting on a button.
It's pretty obvious that no one has opened the case and done a battery pull in response to the flashing red LED. I still suspect that has more to do with potentially violating the warranty, but I might be totally wrong -- almost everyone here seem to have such unshakeable faith in the button-hold reset being absolutely equal in every way to a battery pull!
Conclusion : if I ever brick this N4 and it has a flashing red LED, and it doesn't respond to the 10s power button hold, don't bother pulling the battery, 'cause I already did that.
Thanks for the discussion, folks.
It's been instructive, despite everything.

ATX power buttons are a simple two pin connection on the motherboard, momentarily bridging those two pins with a screwdriver = on/off
The service manual for the N4 confirms that a 10-second power button press does indeed cut the power circuit to the battery.

Engineer here: It is completely possible and very likely that holding the power button on your phone disables current from traveling from the battery to the mainboard.
The way you start a PC with a screwdriver is to bridge the pins that control power. You can do it with any material that has enough conductivity.
If the Nexus 4 was designed correctly (which I have full faith that it was) then pulling the battery is never necessary unless you have much larger problems that a battery pull cannot fix. (bad chips on the mainboard that control the power on/off mechanism) You would be wise to RMA the device regardless.

Have to agree. I worked for over 15 years PC/Server repair, if it's even possible that their was a problem for which the power button did not work, it would have to be something physically wrong with the device which a user could not fix on a smartphone even after pulling the battery, other than by replacing the board itself. The power button off on a PC only fails when it's set to soft-off, which normally requests a normal shutdown from the OS. But as their is no secondary way to power cycle the N4 the power recycle is the more traditional off at the hardware level.
End lesson - if theirs a problem that the power button off does not solve and you can't recover the device, it's a problem better served by the manufacturer on warranty.
Sys Admin here as well and in my 10yrs i've NEVER EVER had the push and hold power button not work. Holding the button on the NExus 4 does create a short in the circuit between the battery and motherboard which is the same as pulling the battery.
You mentioned pulling the power cord the pressing the button will cause the fans to rotate a bit and lights to flash which is true, this is a result of capacitors however and their residual charge that they hold. When you press the power button the system pulls whatever power they have but since it's not continuous, the system then shuts back off instantly.
I have had experience (with dell computers) where the power button would not turn off the computer while on BSOD.
So I see where the op is coming from.
Still wouldn't risk the warranty.
Damn sealed battery, what was Google thinking

About a week ago I had to pull the plug on my Laptop to turn it off I am running Linux Mint 13 KDE with nothing special set up on it it just hung up.
Now with that said I have retired from 32+ years in electronics. I have built computers, repaired computers (among other systems) and taught computers. It is rare for a system like the Nexus 4 to not shut down the same as the battery being pulled. Since it was designed to behave that way. If you really did need to pull the battery then it must need warranty work as something is most likely physically messed up. That does not mean that the switch is guaranteed to remove power under all circumstances as it could go bad.
Attacking someone for not seeing things your way see them is bad form in a civilized community. Which this forum is supposed to be. Yet it happens all the time here at XDA and it is a shame.
Here's an update; it seems one brave soul did pull the Nexus 4 battery. Check out this thread : http://forum.xda-developers.com/showthread.php?t=2111947
And it solved his seemingly RMA-worthy red LED issue. At least till it happened again.

So unfortunately my Nexus 4 will not turn on. I was on CodefireX SR6 and franco.Kernel r53 and I decided to run an Antutu benchmark out of curiosity. It froze up during the benchmark and turned off. It hasn't come back on since.
The battery was fully charged when this happened and I've never dropped the phone. I've tried holding the power button, the power button+vol down, the power button+vol up, all the buttons, and nothing is working. When I plug it into a charger I can occasionally I can get the 'Google' logo to come up as if it were booting then it just turns off again and the LED blinks orange or stays solid orange. I can also get it to fastboot mode every once in a while but when I try launching recovery, it just turns off...
I'm pretty lost right now so any suggestions would be greatly appreciated. Thanks!
Damnit, dude. You're making us (Texans) look bad by not searching.
This happens to people running benchmarks fairly frequently. Plug it in and let it charge for a few hours. If that doesn't work, you may need to crack it open and disconnect and reconnect the battery. There are videos that can help you with that.
Try a battery pull :laugh::laugh::laugh::laugh::laugh::laugh::laugh::laugh::laugh::laugh::laugh:
Actually just search. We have a thread or 17 on this problem, maybe you'll get lucky there.
Thanks for the responses guys. I did several searches yesterday but it seems the majority of the people in a similar situation were able to resolve it by holding the power+vol up/down buttons for some amount of time. I've had it plugged in for 24 hours and I've continued to try things with no luck but I'll look into the disconnect and reconnect of the battery and see what happens.

Good luck, bro! There are some fragile internals, so be careful.
Can someone please give me some advice on what to do. My phone is less than 3 months old and will not power on. It doesn't do anything, not even the vibration it usually does. I've tried plugging it into the charger but it doesn't even have the charging light on. It was working fine and just stopped. I pulled the battery out and put it back in but nothing it working. If If anyone has any suggestions, I would be very grateful! Thanks!!!
what were you doing at the time
What were you doing at the time the phone stopped working? Did you try charging the battery on an external charger?
As the poster above suggested, what were you doing recently? We are looking for clues as to what happened? Did you yank on the power cord, drop the phone, et cetera?
Make sure that your battery isn't in backwards in the phone and try using a different cable to charge the phone. If it still doesn't charge, then borrow a friends external charger.. or even the (charged) battery out of their S5 for a few seconds to see if your phone will turn on. We're trying to differentiate between a dead battery and all other problems.
If you still have no luck, then remove the battery for ten seconds, then replace (the presumably charged) battery in your phone. Then press and hold the volume down key. Then also press and hold the home key, then the power key. After about five seconds, you should see the phone start to the "download screen". If so, post here for further guidance.
If you phone is non responsive to a borrowed battery and the download mode described above, then you should seek warranty service with your carrier. A three month old phone should still be under warranty.

I was talking on it and hung up. Then, I tried to use it about 5 mins later and it wouldnt turn back on. What do you mean by "external charger"?? Sry, I'm not very tech savy lol! The only charger I have is the one that came with my phone. Thank you for replying! ☺

Can you get into recovery ( volume up + menu +power button) or download mode (volume down + menu + power button)?
You may read this article http://www.technobezz.com/samsung-galaxy-s5-not-charging/, hope it helps.
I tried the volume down + home + power and it didn't work. I'm not sure what to do. I don't want to make a trip to the store but it's looking like I'm going to have to.

It is looking like a hardware issue. If you are positive that the battery is charged.. i.e. if the battery turns your husband's phone on, then we ask what is different about your phone? Most software issues would be bypassed by starting a phone in download mode, which is why I asked you to try that.
Have a quick look at the battery "fingers" or pins on your phone. Those are the gold or silver coloured pins that line up with the gold or silver tabs on the end of your battery. Do they all appear to be the same? There isn't one that is bent out of alignment or shorter than the others where it might not be making contact with the battery?
And why not try one more test? See if the phone will start up in "recovery mode" this time.
Pull the battery out of the phone for ten seconds. Then replace it. Now in order.. press and hold the volume up button, then press and hold the home button as well. And last, press and hold the power button. Continue holding all three for ten seconds or until you see the phone screen turn on.
If that still doesn't work, my best guess is that you may have accidentally banged and damaged the power button. If it was me.. I'd try pressing really hard and wiggling the power button for a few seconds to see if you can cajole the phone to power on at least once and confirm the problem.
But that is about all that we can do. If you can't get the phone to power up with a known good battery.. then th store needs to check it with test equipment to narrow down what the hardware fault is.

Hello,
I have problem with my NST. Sometimes it completely freezes. Reset didnt work, I have to replug battery to reset it. And often battery is in bad condition after reset.
Sometimes aslo is situation that in default reading application pages are turning very fast and I cant stop it. you have to lock device (click power button) to stop it.
Also "touch screen" sometimes stooped work. Reset device always help to solve this problem.
First problem is the most problematic for me. I have to remove Torx screw and after that I`m not sure if nook dont need recharge - even if battery was in good condition before freeze.
Have you any solutions?
Hello puszcza,
I having almost the same problems as you.

I never needed to remove the battery. But there were occasions, when I was unable to reset, the usual way. Most of the times, it helps pressing and holding the power button for really long time (20sec). But as my device getting older, it sometimes freezes during boot However what always worked for me, is to plug in an usb cable. After a few seconds my NST booted every time with no trouble. One of my friends suggested - and I'm on his side - that these problems may be related to battery and the power supply circuitry. Poor quality of these parts, can cause voltage levels to fall or be unstable, and make the system crash. It could explain, why things getting worse as time goes by.

I used to face this bug frequently, but nowadays I don't. As far as i can remember, i noticed that when it happened i pushed the UPPER LEFT button. So, in my case, it might be because of the stuck button.
Anyway in the past few days my nook is freezes so frequently, I can't stand it any longer. And factory reset did not help. So I will replace the stock rom, and see what happens. I hope it will work. I will report my results here.
Thank you for repose.
I tried to hold power button really long - didnt hep. When its frozen and I connect it to charge I see green LED light. It should be orange, green is for full-charged.
For this moment I have custom rom, but these problems shoved also on stock rom.
I`ve be glad for totally frozen Nook tips.
So I installed some custom ROMs from these forums. But it didn't helped. Still freezes after some hours, and still the only way to restart it is to plug it in. I really don't have any idea other than some issue with battery.
You might find that your battery is getting old.
You can run a battery utility or my UsbMode.apk and see what the battery is doing.
If you let it run, you might see that your Nook freezes at what should be an adequate battery level, like 40%.
The battery is discharging, then falling off the cliff.
A replacement battery might be the solution.
In my case, I think my NSTGL was freezing sometimes because of ReLaunch (it happened with all versions from 1.3.8 through current 1.4.4), so some time ago I've deleted ReLaunch and using now Zeam Launcher instead - so far no freezing for quite a while. And in my case, I was able to force restart my nook by long pressing the power button.
Update: April 24, 2016 - No, it wasn't ReLaunch, it is Nook itself, and obviously - the battery is the culprit.
