my device has just quit workin all together

my att g2 4.2 rooted stock rom worked normally last night, this morning I plugged it into the car charger and it displayed it was charging with 2% charge present. I pressed the power button the boot animation began I set it down and when I picked it back up a few minutes later to use it...well nothing...the charging indicator led wasn't lit and when I pressed the power button LG appeared for only a split second then went black. when I plug it in same thing, LG logo for a brief second then disappears. I haven't done anything recently except xposed modules, no flashing of anything. any ideas? thank you guys

It happened to me (on other devices) when I let them discharged too far. Just allow it to charge awhile then try to hold the power button
for 10-20secs ... The NookHD+ were the worst in this situation (it won't charge sometimes, I had to plug/unplug a few times to initiate a charge, I was almost about to RMA one of them).

something else that's odd
when I plugged my device into my laptop the laptop acted like I just plugged in 12 different things that all needed to have their disk formatted. what is going on? wierd

try charging the device in offline mode ( turn it off and let it charrge for a while) and then turn it on . mind wouldnt turn on because of very low charge yesterday. doing this helped

update
I let it charge for several hours, nothing...it appears to be in some kind of boot loop. I can't turn it off all the way, I hold the powwer button for tensec or so and the LG will appear for a second then disapear and then the back light stays on. oh ya, when I plugged it in a few hours ago it wouldn't turn on but the red LED was flashing. I'm not sure how long it stayed on, but it was off when i got back to it several hours later. thank you for your time fellas!

If you can get to recovery at all, leaving it on charge in there. Has saved me in a similar situation.

Could have been the power switch that makes the phone short circuit and goes off anytime.

Thank you sirs, unfortunately still no good

it sounds like you had the same thing as everyone else yesterday that had twrp installed and the carrier automatically updated the system.
I could not get my phone recognized by the laptop and had to use pdanet drivers, which finally worked, but I still had to dig for the device. then had to flash back to stock. There is a pretty good thread on this topic, already. Search for it in the developer section. Do not skip any steps, such as setting the date back to jan2012 and turning off the internet. go slow and methodically, or you will miss a step and get frustrated.

[Q] Is my phone bricked or is it a simple battery issue?

Ok so yesterday I had my nexus 4 in the charger at 46 percent and i was about to send a tweet when the screen froze. thinking it was a simple crash i pressed the home button and no visual response then it powered off. now whenever i try to power it on nothing happens. i tried pressing the power and volume buttons. whenever i try to turn it on and i plug it in the red light flashes. sometimes it flashes continiously sometimes it is a solid color. so what can i do it wont communicate with the computer. im not sure what the issue is. is it a battery issue or is it impossibly bricked. i already charged it overnight to no avail.
oh and im running stock cm11 with the stock cm kernel. i just installed it the night before.
im planning on just openning it and unplugging and plugging the battery back in. will this work?

Try power button + volume down for 10 seconds and than plug in the power cable. You somehow must try to boot into bootloader.

How many times did you try that? It may don't work in the first time.
But if you can screw off you phone, that I would suggest to look after the batterie :good:

It is hard to say, because there are so many reason why your device doesn't boot only left the red LED flashing. One reason could be your batterie which is bricked. Another reason could be a thermal shutdown cause by overheat. And of course there are those little, little software issues that only appear once in five years...

[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.

The battery will charge with a NCF Charger
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...

I have checked all kind of videos there. Also that one. Most of these cases are related to battery, but it seems in my case it isn't. I just searched for QHSUSB_DLOAD unrecognized device, all posts says it means phone is bricked... But cmon, how? I installed CM12, successfully, without any errors, then just restarted phone, and its dead...

Did u try booting the phone without battery by connecting to wall charger and what about flashing stock ROM via PC
Also check that the power button works
This case should be solved

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.

S8 beeped 3 times loudly, shut off and has blinking red LED, won't turn on

Well color me bummed! Have had the S8 for a few days, stock, only added 3 apps so far, sidesync, Clash of Clans and Lastpass.
Anyway this morning, the phone was at 58% remaining battery, running fine.
Then it beeped a weird tone 3 times, shut down and started blinking a red LED on the phase of the phone.
Samsung support had me hard reset it (which I was going to do but you know for the sake of reporting the problem I went through official support channel)
The hard reset got the phone working, it booted, shows 59% and the red LED which initially did not turn off on reboot has turned off.
So, just fyi for the community, and if you have any feedback on not trusting a device that needs hard reset so early in it's life, let me know.
Oh and the Volume Down + Power Button held down is the reset for the device.

I was messing around plugging and unplugging and my S6 did something similar. Even with a hard reset it came back in the same state-which included a frozen screen. I had to boot into recovery mode then do a factory reset.

Okay, well funny you say that because I was also messing around with the charging too. I specifically was setting it down and taking it off a QI charger from NeWisdom right as I set it down again, it did this. Maybe I did it more than a few times consecutively checking if I was getting fast charge notification.
Just to slap it into this thread, how do you get to recovery? Both volumes and power hold down?

I have had mine reboot itself 3 times, all just after i unplugged it from my PC, so again that might be related to removing a charger (although it hsnt dont it yet when charging properly).

S7 Edge isn't turning on

Hello.
So, I recently updated my phone 2 days ago for the first time after 2017, and the battery ran out while it was updating, and then it was boot looping and kept getting stuck at 28%.
I decided to reinstall the os on it (I installed the official rom that the phone came with). At first, everything seemed normal until I plugged it and after a while, the led indicator was showing that it was still charging but after I unplugged it from the charger, the light was still on and the screen was completely black and unresponsive.
After a while, the light shut off and after that, it never came on. I tried everything to get it on again: tried hard rebooting, trying to get into recovery, charging with different types of cables and with wireless charging also, basically every combination that came to mind. When I used the wireless charger, it showed that it was charging, but no signs of life on the phone. Samsung support wasn't that much of a help either, they only asked if I used a cable that worked on it and if the phone was water damaged or had any cracks.
Any help will be appreciated!!!

How did you reinstall the OS?

by putting the phone into download mode

Connect usb (not charger) hold vol- + home + power, release power after 5 sec n continue holding vol- + home . If download mode appears flash phone with same csc firmware. If no downlooad mode probably battery or emmc fault.

Yeah nothing really appeared. So I'm guessing its emmc fault?

Or battery

i mean the battery was working normally when i used it last time

If its an emmc failed qualcomm cpu S7e , pc will detect as qualcomm 9008 port.

For battery you need to manually check battery voltage.

This same thing happened with my s7 edge 3-4 months ago.... i was installing some apps from play store... as usual the device was high at temperature..it turned off... for next a couple of days it was only rebooting when it was very pleasent at temperature... and sudden shutting down within minutes.. the last time it did not turn on but the blue light was on for 4-5 days until it decharged... when the battery fully drained it never accepted charging or turned on yet... i miss my s7 egde... i had many useful data saved in it.. i lost everything..
I know it was the cpu failure...

Looks like RAM failure. Heating phone's back side(after removing back panel with hair dryer for few seconds may help. Not a permanent solution, but for data backup.
