[Q] Mt4G won't boot AT ALL

I went out for a while with my battery at 20%, when I came back it had drained out. I put it to charge, but when I tried to switch it back on, it refused to boot. On a normal power button press, it would vibrate 3 times and then the red notification light would start blinking. Same thing with power + volume_up. If I press power + volume_down, it would vibrate 5 times and the green notification light would stay lit. Nothing comes on the screen, whatsoever.
I was rooted with S=off, and was using the Operation Inferno ROM (which I have been using comfortably for the past month or so).
I did try some stuff with ADB, such as using it to reboot into bootloader and recovery (same 3 vibrate + red notification light), pushed the Operation Inferno ROM again to the sdcard and tried to restore the ROM from that location (for which I got adb: unable to open file /sdcard/backup.zip).
I haven't yet gotten around to downloading and installing the factory image some have suggested for the eMMC issue (PD15IMG.ZIP) but I wanted additional opinions considering most people with an eMMC issue have been able to open HBOOT at least.

When the phone doesn't power on, neither ADB nor fastboot will help you. There is no device on the other side, so all your attempts went to the drain, and it was expected. Nothing to do with eMMC issue or anything else. Your phone just doesn't power on.
Put your phone to charge, if the light turns orange - just leave it to charge until it's green, then disconnect and try to power on.
If the light doesn't turn orange, or it doesn't power on even after charging - remove the battery for 10 min, press Power button for 1/2 min, release the button, reinsert the battery, put to charge. And again, let it charge before you try to turn it on.

I did charge it earlier (for about half an hour or so) and the orange light does come, but it didn't boot after that either.
I'll just give it a try by charging it through the night and see.

I think a key thing is to take out your battery for 10 min, as Jack_R1 suggested. Then proceed with the charging.

Still doesn't work. I dissembled it and kept it like that for quite some time, then put everything back and charged it for hours. Still the same issue happening during boot.

Connect the phone to USB, powered off, see if the PC recognizes "QHSUSB_DLOAD" device. Try to power it on, see if it happens.
If it happens - it means your primary bootloader is screwed, in another words - no repair (actually, repair is theoretically possible, but no guide, no information and no sources exist for MT4G).

When its plugged in, its recognised by the ADB (even when powered off), and I can do some basic commands (mentioned in the first post). When I power it on the same thing happens as when it wasn't plugged into USB (ie, the vibration and the blinking LED).
I'm also worried about water damage, since a very tiny amount did come on it as I was sweating profusely. Although the indicators in the battery tray and on the battery itself don't signal damage (they're completely white) I've just decided to try and keep it opened up in a bowl of rice, just in case, until someone is able to come out with some idea.
As I'm in India, taking it to T-Mobile is not an option. If nothing works out, I might take it to HTC and see if they can help out.

N4 Bricked!! No responses! Just red led when I plug in to AC/USB

Hello guys, first than nothing, sorry for my bad english, isnt my native languaje. I got this problem yesterday in the night of the new year!!!!!!!:crying: I was rooted, using Xylon and Faux Kernel, but the problem appears from nothing!!
The first thing that I detected was, the phone take a WHILE!!! for charge.... then, out of the power, the phone get overheating and discharging so fast, never in life that happends, when N4 got discharged i try to turn on again but download mode appers in the screen, finally I get in the recovery, then I did a wipe cache/system and factory reset. Install again the Xylon... but when phone finally turns off, when I plugged in to AC absolutelly nothing happends, the led just turn in red, and the N4 dont start in FB, dont get charge, dont do a sh*t !!!! I conect it to the PC but also nothing appends, the N4 doesnt appear in my device list.
So... my N4 its broken?

There was possibly something wrong with the kernel and rom combination that caused your phone to overheat. I think eventually the heat may have damaged your hardware. Sorry but, if something was wrong in the first place it was not a good idea to reinstall the same thing that was causing the problem, if I were you I would have flashed a stock ROM. My only advice now would be to RMA it and pray
EDIT: I found this if it helps at all:
If you are unable to access the settings menu of your device, you can still reset your phone by performing a Hard Reset. Here are the instructions:
If your phone is on, power it off.
Press and hold Power until the device powers on, then immediately press and hold Volume Down (while still pressing Power). You will see the word Start with an arrow drawn around it.
Press Volume Down twice to designate Recovery mode.
Press Power to restart into Recovery mode. You will see an image of an Android robot with a red exclamation mark.
While holding down Power, press Volume Up.
Use the volume keys to scroll to "wipe data/factory reset" and press Power to select it.
Scroll down to "Yes - erase all user data" and press Power to select it.
Note: If at any point during the above steps your phone becomes unresponsive, you can restart it by holding down the power button for several seconds.

Before you try anything else, try and leaving it plugged in for a while and then try turning it on. Or leave it plugged in to a computer then try turning it on.

Try this. I haven't had it happen to me, but I do have a friend who this exact same thing happened and he thought it was bricked. He left it plugged into AC over night, and in the morning it would turn back on.

First than nothing, thanks for reply, I appreciate your intentions to help me.
I will leave it charging all the night and while Im working too... I hope after that, the phone at least turn on.
I dont install the STOCK ROM because I dont have it in my internal memory and I was in my girlfriend house, the night of the 12/31/12, there is not much to do...

It could be bad battery, how long did bought of you had working phone, how many times did you charge?
Did you use out of the box charger?
Did you have problems with usb jack?

I bought it the 13/nov..
I received it 29/nov.
I ALWAYS use stock charger, only 1 time i try to charge it in my car, but it was less thant 5 minutes, I decided dont charge with the car because the energy variates when I accelerate...
After that, I use my phone quiet normal.

I had this problem with my nexus 7. I think my battery died all the way and it couldn't charge. The stick charger wasn't doing anything. But I plugged it into my computer for a few minutes and tried turning it on. Then when the loading screen appeared I ran it to it's stock charger and charged it to full. Your battery probably died. Try different combinations of ways to get it to take a charge. Just long enough to turn on then plug it into its charger. Though the overheating could have fried it

[Q] N4 doesnt turn on. Red Light blinks once.

Hello.
When I try to turn on my N4, I hold power button, and after about 10 seconds Red light blinks (just once, if it's connected to USB that 1 blink last for 3 seconds, if connected to wall, it's just quick 1 blink. If it not connected anywhere there is no action at all, it just stays dead, no blinks, nothing). Same if I try to go in bootloader by holding volume down+power.
This happened after I successfully installed CM12, with no errors. Then I rebooted my phone, and it just stayed black as it is now. Battery was around 25~30% that time, and phone was connected to USB.
Did I bricked my phone totally? I am now trying to charge it up already for 1 hour... but it nothing changes.
I have searched here for similar problems, but couldn't find solution...
Edit: Charging already for 10h+ , still same..
Edit2: I removed battery, reconnected after a while, still same problem.
So I tested it with multimeter, it says 2.6V, but fully charged must be 3.8V. Could this be a problem? I was charging it for whole night.
Edit3: I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...
When I connect to PC usb, there are unrecognized deviced called "QHSUSB_DLOAD".

easy fix
Hold down the power button and the volume down button at the same time until phone reboots. If you see the little android no need to worry just let go and wait for your device to reboot on its own. This is not a factory reset it's just like restarting your device. :good:

I have tried that many times. Nothing. It's bootloader screen, but I can't get there. Nothing happens. If I keep holding volume down+power it just keep blinking once every ~10 seconds, same if I hold just power button. If phone is not connected to charger, there are no blinks at all.

I removed battery, reconnected after a while, still same problem.

I had the same problem a year ago, I tried to remove the battery, charging all night, and other solutions that I found online and no one worked.
Finally I found here in XDA a user with the same problem and his solution was charger the phone with a wireless charger, a friend of mine has one and I put the phone to charge and after a few minutes the screen goes on and the phone was charged, then I press power button and the nexus run again.
Hope this works.
Sorry for my bad English, I'm from Spain.
Good luck.
(I bought a wireless charger in case it happen again)

I don't know anyone with wireless charger. I already ordered a new battery, and then I probably will get wireless charger also. Ty.
But this problem is very weird if you think so.. I think it happened because of many aspects together:
1) Battery was already below 30%
2) I pretty regularly charge phone with USB (won't do it again)
3) It was connected to PC USB in same time.
4) I installed CM12 ROM in same time
So main reason I think is USB, that I restarted phone while it was on pretty low battery and with USB connected.. phone restarted and got invalid voltages and couldn't even boot up or charge phone. I also found an article which says, minimum voltage, when phone battery has 0%, it's 3.0V, so I was below that.. it just screwed everything and battery died. Well, I am not sure for 100% that it's battery fault, but I hope so, I really love my N4 and still wanna use it for long time, I hope it's not dead phone, just a dead battery. Lets see! I will update this thread , when I get my new battery (less than month probably).
Sorry, my english is also not perfect. I am from Latvia.

I was playing when it happened to me. The phone was very very hot and the battery was around 70%. When I put in the wireless charged and I can reboot the phone the battery was at 65%, so it had charge but the phone won't boot.
I charge my phone almost every day, sometimes with AC, others with USB (plugging to PC) or wireless that depends of my needs
I hope you can fix it. Good luck.

Btw. Do you know if battery charges with wireless charger, if it's removed from the phone?

Don't think it does, since the receiving coils for wireless charging are located just behind the glass back.

Major Issue Google
This "Nexus SOD" issue is showing up on many sites across the Internet. I have multiple "Nexus" devices including 2 Nexus 4, 1 Nexus 5, 2 "Nexus 7 2013". It suddenly started out of the blue with one of my Nexus 4 phones. Symptoms included rapid battery discharge. I am using Lollipop 5.1 on all devices. There are many claims as to the cause, Hardware Motherboard, Power Button etc. Others claim it is "Software Related" or App Related. The problem effects Nexus 4 and Nexus 5 phones. I have ordered a new motherboard for my nexus 4 device and see if that makes a difference.
This problem should warrant a "Major Android Lollipop Crisis Team" by Google to investigate the cause and let us know what it is and what Google is doing to solve the problem before moving to announce "Android M". This issue needs to brought up and actively pursued at the upcoming "Google I/O Conference" by the strong Android Developers Groups to press for "Formal Action"

I had this problem a long time ago and my fix worked for me after doing a little research it seems like this is a case called battery total discharge. The fix was simply to charge your phone using the wall adapter that came with your phone (I still use my old apple cube wall thing) and to wait for the red light to appear then wait about ten minutes before trying to reboot.

I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...

Just tried booting without battery, and connecting to wall. Same - red light blinks once, after I hold Power button or Power+Volume down for about 15 seconds. If I keep buttons pressed, it just repeats every ~15 seconds.
Power buttons works fine.
After I checked that Device manager thing in google.. it looks very bad.. phone is dead.. probably need to change motherboard. I am just shocked, how this could happen... I didn't receive any errors during CM12 installation. Phone just instantly died after restart.

Is my phone a bricked lost cause?

I was running a standard OS, no root/custom/anything (mostly because I couldn't find a compatible hack). Anyway, I had my phone running happily for ~2+ years, no trouble at all, but few days ago I left it charging for 2-3 days (it powered down due to lower power before that). I've done it before several times, but when I tried turning it on, it was stuck on Samsung logo (white on black). I restarted, it was stuck a bit further on the colored startup animation. Third time, stuck on the logo again. I turned it off, but it was a bit warm after 10 or so minutes. I tried charging it - it showed the usual green battery charging from 80% or so. I took the battery out, pressed the power button for a minute for some hard reset, but the battery back in, and from that point on it seems I have a brick. No reaction to power button, no reaction to charging. Power+Home+VolUp produce no reaction, either.
Is there anything I can try, or should I just give up?

Factory reset ??
Flash stock rom via Odin ??

The only answer I can think of is that your battery is dead. I would try to use another battery before getting to the conclusion that your phone is completely bricked. Or just let the battery out of your phone for a couple of days and try again later.

Must have fried something. The only thing I would check now is to connect it to a PC with a USB cable and see if the PC detects something, ANYTHING. If it makes sounds that something has been connected to it. I remember when I hard bricked my phone, it did not turn on at all but my PC still sort of detected it. I guess that is the only thing left to try to give you a definite answer

Rooted now frozen in Installing Screen. Cannot restart.

Few weeks ago I found wife's old NST (non-glowlight model) in working order and decided to root it. Rooted it, played around with it. Wasnt too impressed, so just threw some ebooks for my kid to read while on vacation. Left it on my desk for a few weeks as I got busy with work. Today I picked it up as my son's vacation is next week and it's frozen on the "Installing... A new software update is being installed This will take a few minutes" screen.
I mean I googled for several hours, the hold the power button for 20 sec method....the hold the power and the "n" button method, I charged it, indicator light is green. I even opened it up and pulled the battery cable..... NOTHING WORKS...]
Please help. So weird...it was working fine and now frozen.

And I guess the drives don't mount successfully. Well, disconnecting the battery should certainly turn it off. If reconnecting makes it start spontaneously (should not), you could prepare a Nook Manager sdcard and insert it before reconnecting the battery. But this sort of sounds like the ability to boot is lost. Hmmm. I'll have to think about it.

unfortunately disconnecting the battery does not appear to do anything... screen continues to show that 'Installing... " screen. Hoping to get this thing figured out with someone's help

E-ink screens stay the same unless there is a new powered input so it could simply be off, having run the battery down completely during an update (maybe Wi-Fi was left on? That would run down the battery for sure). So if all of this happened during an OTA update, it could be really messed up
When my NST is off, plugging in the power pack turns it on. Initially the LED is green and then changes to orange as charging begins. I'm assuming nothing happens when you do the same. If the OS is scrambled from losing power during an update it may not be able to boot. You didn't say how you rooted. If you used Nook Manager you could try putting in that card and then connecting to the power pack, hoping for a boot from the SD card. If you got that far you could try a factory reset.
My power button is sometimes really cranky and a few times I've run through my entire stock of words that do not come from children's books trying to get the device to turn on. So you might try, but if it's really off the power pack should turn it on.

Power pack = charger.
So if the Nook is actually off, attaching the charger with the NM card inserted should make it boot. Did you try the procedure in the link above?

Just tried the procedure of unplugging the battery, holding the white power button for 30 secs, then connecting battery and connecting to charger. There is a split second orange light and then green the first time i plug it in....subsequent plugging results in always green....the issue with the frozen screen on "Installing" remains. Tried the holding x 20 secs method to promt a restart....nothing.... what else can I do?

If the battery is actually "dead" (not impossible on these old devices), the NST will not start, even if plugged in. Do you have a voltmeter of some sort to check the battery? If it's actually charged, it should show a solid voltage. If not, that may be the issue. If the battery is actually charged then there's a pretty serious issue that can't be fixed without access to the OS by ADB, or the ability to boot from the SD card. Beyond my "pay grade", at any rate, I'm sorry to say. There are batteries available online but the price may not make sense.

I don't think it's a battery issue. I had another NST with a good battery but a bad screen (lines all across screen) . I fully charged it using the bad screen reader and used the battery from it for the frozen nook... no luck.. oh well... I guess this is a paperweight now... thanks for your help everyone.
