[Nexus 4 Q&A, Help & Troubleshooting] reaper000:
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?
[Nexus 4 Q&A, Help & Troubleshooting] abnormalreply:
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.
[Nexus 4 Q&A, Help & Troubleshooting] reaper000:
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.
[Nexus 4 Q&A, Help & Troubleshooting] Eric-1987:
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.
[Nexus 4 Q&A, Help & Troubleshooting] greg17477:
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 ;)
[Nexus 4 Q&A, Help & Troubleshooting] republicano:
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,
[Nexus 4 Q&A, Help & Troubleshooting] reaper000:
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...:D

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.
[Nexus 4 Q&A, Help & Troubleshooting] Rusty!:
ATX power buttons are a simple two pin connection on the motherboard, momentarily bridging those two pins with a screwdriver = on/off
[Nexus 4 Q&A, Help & Troubleshooting] steviewevie:
The service manual for the N4 confirms that a 10-second power button press does indeed cut the power circuit to the battery.
[Nexus 4 Q&A, Help & Troubleshooting] diablos991:
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.
[Nexus 4 Q&A, Help & Troubleshooting] movielover76:
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.
[Nexus 4 Q&A, Help & Troubleshooting] shotta35:
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.
[Nexus 4 Q&A, Help & Troubleshooting] Censura_Umbra:
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
[Nexus 4 Q&A, Help & Troubleshooting] donec:
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.

Hi! I've pulled the battery on my N4. I'm the guy from that linked thread. It was absolutely different than using the power button, it actually worked and has, hopefully, solved my issue. I can't say this with any level of certainty, but I'm considering the idea that the benchmarking software caused the issue. (Quadrant)

Diagnosis: battery not holding a charge

Yeah -- my phone developed this problem this afternoon out of the clear blue sky. It's 100% stock, never rooted or unlocked or anything. Symptoms are as described: won't boot, displays flashing red LED when plugged into power.

Observations: first I opened my phone up, pulled the battery, re-connected the battery. No change.

Next step: disconnected the battery, plugged into external power with battery still disconnected. While the phone was displaying the battery charging screen (strangely, since there was no battery connected), I re-connected the battery and was able to power up the phone. The phone reported 0% charge, but went through the motions as though the battery was charging. At 25%, I disconnected external power and the phone instantly played the low battery chime, then went black. I disconnected/powered on/reconnected the battery and the phone rebooted again showing 0% charge. I let it go through the motions of reaching 100% charge. When 100% charge was displayed, I powered the phone down normally, disconnected from external power, and attempted to power back on. Result: flashing red LED.

Looks like the battery is not storing a charge. (Or, alternately, the phone thinks it is supplying power to the battery when it actually isn't.) I will be requesting an RMA as soon as I can get my hands on a working phone to call the RMA dept. They better not give me any hassle for opening the phone up.

[Nexus 4 Q&A, Help & Troubleshooting] parity206:
UPDATE:

So, I did the voodoo ritual one more time, that is, I disconnected the battery, waited a moment before plugging into external power, waited until I had the battery- charging screen, then reconnected the battery and booted the phone. As before, the phone reported zero charge and went through the motions of charging, and, also as before, I did not trust it.

But I kept it on external power overnight so I would at least have a phone. And in the morning, in a fit of boldness, I disconnected the external power and held my breath waiting to see how quickly the phone would go black. To my surprise, it didn't. The battery appears to be functioning normally again.

AFAIK, I am the first person to revive an N4 that went red-LED this way. (???)

What appears to happen is the battery dies, and cannot be recharged with the phone off. The only way to recharge is to get the phone to boot using the process described above, and then recharge it (overnight?) while the phone is powered up.
[Nexus 4 Q&A, Help & Troubleshooting] reaper000:
You might indeed be the only one (thus far) to do the voodoo ritual, as you described above. But now your method is part of the database, and may help someone in need. Thanks for posting
[Nexus 4 Q&A, Help & Troubleshooting] parity206:
Update to the updated update:

Received & installed a replacement battery. Discharged it completely and was able to recharge and reboot the phone without red LED's or other difficulties. I feel fairly confident in saying that the problem is curable by replacing the battery and can be worked around in the meantime using the method described in my earlier posts.

I was running CM10 on a rooted TFT101. I was having some WiFI connectivity issues so I decided I would try out a new rom. I used Titamium Backup and backed up all my needed files to my Mico SD card. Once backed up, I rebooted into CWM v6.0.1.3. I went to do a factory reset prior to flashing the new rom. The tablet just froze. I rebooted the tablet back into CWM. I tried to again do a factory reset and again the tablet just froze. I tried to boot back into CM10 and I just sits and spins and never actually boots into the OS. I decided that I would just go ahead and just flash the new rom and do a factory reset after the fact. I placed the new rom on the micro sd card and booted back into CWM. I attempted to install zip from SD card and now I get e:can't mount /sdcard/. I have tried 3 different micro sd cards and nothing. I have formatted each to fat32 and not one of them is recognized. All 3 are recognized by windows.

Since I can't boot into the OS...and I can't load a new rom....I am dead in the water. Any help would be greatly appreciated.

Thank you in advance.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Lethe6:
If you can get it to that endless boot logo and connect it through USB, ADB (info - download) should be able to access whatever's left on your device assuming it gets far enough in the boot process. If it does, you can adb pull the backups to your computer to save them.

That being said, Easy Flasher will help you get back to 100% unrooted stock and "unbrick" your device with a few clicks. Then you can start over with a new recovery and rom. But it will wipe your entire device clean, hence why I suggest you first check if you still have backups and if you do, pull them on your computer using adb.

I can't help with the CWM problem, I haven't used it in a long time.
[Eee Pad Transformer Q&A, Help & Troubleshooting] champs777:
Thank you Lethe6. I saw that option and wondered if that might help me. I will try it out today.

The N4 has already been flagged by AT&T as a smartphone and multiple people have posted. Figuring out whether a phone's dumb or smart is very easy for AT&T (or any other carrier) as the first eight characters of the IMEI identify the make and model (Type Allocation Code) of the phone.
