[Q] Unresponsive when off charger - Epic 4G Q&A, Help & Troubleshooting

Hey all, long time lurker first time poster.
Having an issue with my Epic becoming unresponsive while not in use. I originally had ACSs SRF 1.02 when the issues started on Saturday, and I had been running that without issue since it came out. After any period of not being used ranging from 30 mins to maybe 2 hours my Epic will not respond to the power button or sliding open the keyboard. No lights turn on or anything. However, it does not turn off as far as I can tell, as holding the power button as if I was going to turn it on has no effect. I have to pull the battery and restart every single time. I thought maybe the phone didn't like something with the ROM, so I wiped and updated to the latest SRF (1.2) and flashed the EC05 modem. The same issue kept happening so I tried changing to the Genocide kernel to no effect. I thought maybe the CPU was running too slow so I tried changing the operating frequencies to eliminate 100 and 200 mhz, first with setCPU and then with Voltage Control. None of these have had any effect. But I do not have any problems when the phone is charging or being used, so I think it either has something to do with those, or maybe something with the battery. Before I go out and buy a new battery I thought I'd see if anyone on here had any other suggestions. Any thoughts?
Any help would be greatly appreciated. Thank you.

That happened to me after I dropped mine. Worked fine while charging, but if I let the screen turn off while it was off the charger, it would "freeze" like you described. Its not the battery, cause I still have the old battery, and I've used it in my replacement. I think its a hardware problem.

[Q] Rooted CM7 Incredible will not turn on or charge

First of all I'm new here so apologies if I'm asking a question that's been asked before.
My situation is this:
My girlfriend has an HTC Incredible. It's going on 18 months old. I rooted it a while back with unrevoked and loaded CM7 on it. It ran perfectly for quite a while. Lately, she's been experiencing a problem with random reboots, I'd say over the past month or so. She said it would reboot when she had it plugged in to her work PC so she can listen to Pandora and keep a charge. Last night in an attempt to stabilize it and prevent the reboots I loaded Go Launcher on it and made sure she didn't have an malicious apps. Well, today apparently while she was working and had it plugged in to her PC via USB it rebooted and got stuck at the HTC Incredible screen. So she pulled the battery. Since she pulled the battery, the phone will not come on. I've tried the power button plus the volume down, the power button plus the optical button, everything. The charge light won't even come on. So, any help from anyone would be much appreciated!

This may sound stupid but did she put the battery back in right?
Yeah, she did. I don't get it, I've googled the issue and I can't really find anyone having the same problem.
If you can't even get into hboot, it ain't good. Any way to try another battery just to rule it out?
power button + volume down + middle button is the ultimate reboot.
and yea I say try another battery -or- charge the same battery in an external charger and try it again. If not then something really weird happened to that phone..
I'm going to try a new battery tomorrow. Dumb question : Can a battery just die like that? I've always thought there would be warning signs.
The random reboots are the warning signs. My phone was randomly rebooting last month about twice a week then one day it rebooted as I stared at it six straight times. Apparently my battery (it was a Seido 1750) was known to flake out after a few months according to reviews on Amazon reviews. These reviews were posted after I had my extended battery for a few months so I was unaware. I switched to my stock battery and I have gone four weeks without an issue.
My seidio 3500 occasionally likes to discharge in an extremely rapid fashion. I hope I don't have to go back to my stock battery... Ever!
Happens to computers. Power supply starts to go bad and you begin to get phantom restarts. Then your PC is dead.

Tried a different sd card? Note that cm interacts with the sd card during boot.

Thanks for the help everyone. I finally tried a new battery. Doesn't work. The phone still will not charge. I'm at a total loss as to what to do. If nothing else works, I'm upgrading my Droid X to the Droid Prime (when it's released) and giving her my X. If anyone has any additional suggestions...it would be greatly appreciated.
I would throw that usb cable away...
If the cable is shorting out it can kill our phones because of the extra pins for TV out in the micro-usb port on Inc. +5dc on a video out line might have toasted it.
Just a thought.
good luck

G2 Keeps Shutting Off

So I bought my G2 off of craigslist and the guy I bought it off said it was a refurb (still had the plastics on it and everything). As soon as I got home I rooted it and installed CM7. I love this phone but I've been getting random shutdowns multiple times a day. I've noticed that it only happens when the screen is turned off.
I searched the forum but couldn't fix it with the suggestions I found. Battery is firmly in place, sd card slot locked, etc. I tried different ROMs and kernels but nothing seems to work. Am I out of luck?
Sorry to say, but you probably are SOL. I bought a G2 new from RadioShack in May and installed cm7 immediately. I had the same problem for months, or rather, mine will restart randomly. It seems to be intermittent though, sometimes it'll go days without happening, and other times it will happen repeatedly all day. Installing ICS hasn't helped either, so I thought it might be because of custom roms, but its not. My dad uses a stock g2 and has the same issues.
I have found that it seems to happen more whenever there is low/no cell coverage, when switching between tower and wifi, or after changing any radio state. Hopefully someone will come up with a solution for this apparent hardware problem. :-!

When the phone shuts off, can you turn it back on with the power button; or do you have to pull the battery, reinsert, and press power button?
Is the GPS on while the shutdowns occur?
If you've tried various ROMs and kernels, I'd say that its likely a hardware problem. In that case, there is not much you can do.
Even refurbs have some kind of warranty (on AT&T you get 30 days). So you should contact the seller and see if he can exchange it with T-Mob for you.
I had the same issue, mine would shut off when screen was off, would need to pull battery to restart. I read somewhere(when i find the link I'll post) that turning the GPS off fixes. I turn off gps when not using and the issue went away.
More info in this thread... Seems to be hardware issue and answer is to send in, I just tirn off the gps when not in use and I have no issues.
>G2 and Desire Z>G2 and Desire Z Q&A>[Q] HTC Desire Z Freeze During Standby Mode
http://forum.xda-developers.com/showthread.php?t=908095&page=6
Thanks for the responses everyone. I can turn it on normally after it shuts off, no battery pull necessary. A weird thing is that sometimes when I wake the phone up I can actually see my G2 in the process of shutting off. And I keep my GPS off, so it's not the sleep of death problem either. Just a regular shutdown at the most random times. So you guys are probably right that I got a lemon.

Galaxy nexus randomly shuts off..

So...my girlfriend's galaxy nexus started randomly shutting off in the past few weeks..it was completely stock..so i decided to root it, change the kernel, ROM and baseband...
However, it still does it with no particular pattern..the only consistent thing is that it seems to happen when we're out of the house..not turning on or off any particular wireless service like wifi Bluetooth etc...i even tried tapping on the back a few times like some other forums suggested...but that didn't recreate the problem..so I'd really be happy to hear any troubleshooting/suggestions/etc..

heat? is it getting hot? the phone has a safety to shut odd when the cpu temp reaches 110C. but i find it hard to imagine that it reaches 110C just sitting there(unless its plugged in, sitting in a non ventilated area).
If it's doing that and its stock and unrooted then you need to take it back
forgot to remind you to return to stock & locked before taking it back....if you choose to do so

Yeah...i don't think it gets that hot
The phone is just usually in the car..and I've had the chance to hold it right after it shuts off..i wonder if taking the case off..in case, like you said, ventilation might be the problem..

Definitely..the root toolkit helps and i would able to flash a stock image and relock the phone..
just an extra bit of info in case someone googled/searched for this same problem and fell on this forum...
because after my searches, everyone that has had the same problem doesn't seem to have an answer...and now my phone, who did it a few times in the first few months...now has started to do it almost consistently...
randomly when i leave the house, it just goes to sleep and then the phone is turned off
the phone is NOT hot and it's literally minutes of being in the car or going for a walk, without bluetooth or gps or wifi on...and even when it is, sometimes it will still turn off
no pattern at all...both rooted and not, stock rom and not...stock kernel and not (have tried stock, james bond, and trinity so far)...
i'm going to try uping the min frequency and different governors to see what happens...
i will keep this thread updated
Try to see what happens if you hold the phone screen up and drop it 1 or 2 inches.
I am currently on my 5th Galaxy Nexus from Verizon. Phone 3 and 5 had a problem of turning off in my pocket. Almost every time I took the phone out is was off. I finally discovered that any jarring movement turns the phone off. If I did anything more then gently place it on the counter the phones would shut off. This occurs with the standard battery and back and the slim extended battery and battery back. The phone is inside a Seidio Convert case and this still occurs.

it seems like there's a good chance that's what's happening...as a fresh boot/install of any rom, including stock, and any kernel, any radio, all cause it to randomly shut down. but i noticed if it's NOT in my pocket and i hold it in my hand it almost never ever shuts down...so i'm thinking this is the problem...will keep this updated..thanks
I'm on my 4th Nexus because of "randomly" shutting down
As much as I love my rooted Nexus (4.1.1 ) full_toro_userdebug, after a couple of weeks, each phone has been shutting off randomly in my pocket or just jarring it in any way. I finally seemed to have fixed it by putting a small block of tissue paper the size of the battery between the case back and the battery.
It has allowed me to drop it from an inch or two above a wood table as drop it....It is 24 hours now. I will update with any change.

Any updates from you? I am having the same problem in that my screen will turn off and I can't get it to turn back on without pulling the battery. I can tell the phone is still on because LED notifications will continue to blink but the power button doesn't do anything.
Interestingly I've noticed lately that after I pull the battery and restart the phone, it seems to reset the battery stats. For example, tonight my phone has been off the charger for about 2 hours but after I just had to pull the battery, it booted back up and battery stats say it's been on battery for 24 minutes only.
Anyone else experiencing anything similar?

had this problem for several weeks: as long as i used the phone everything went fine but when i put it to sleep and stuff it in my pocket it shut itself down every second or third time.
your tipp with the tissue paper did the trick for me, no shutdown in the last five hours. thanks!
Has anyone found the reason for this happening? first time in eight months, my nexus turned down. first few turning offs phone has been hot and battery normal (70 ,80%). the last time the phone was cold and empty battery (although it was full). i am on custom rom (AOKP).

I suspect the phone is turning itself off because of a bad battery connection. I've had my GN for several months and it has just started turning itself off whenever it is in my pocket, and occasionally when I'm holding it. It all began after about a 4 foot drop which caused no visible damage. Reseating the battery appears to help. I hope it's this simple for everyone else.

i do not think that the battery connection is here a problem... when the phone was ˝off˝ i tried to call myself from mothers phone and everything was normal (in speaker of her phone it was ringing), but my phone was dead... nothing..
so i came to the conclusion that the phone is not exactly turned off, but the screen is and the power button does not work also. that is why i cant ˝turn on˝ my phone.
looks like the phone is in some kind of standby, but i dont know why this happens, maybe it is rom issue... i switched from AOKP to CM10 and so far (4 days) the phone has not been turned off by itself.
battery connection for me

I agree with the battery connection guess. I had the same problem of it turning off randomly and it hasn't happened to me since I cleaned off the connectors on both the battery and the phone. Good luck to everyone else!

do you also have dream scene enabled? i have noticed that when i have my nexus plugged in and the dream scene is on that it is hard to get it just to the main passcode screen upon hitting power button.
now the phone just randomly turns off , while in the middle of charging sitting completely still on my desk.
wtf is going on with this phone?
I had this issue when I first got the GN.
Unfortunately, I think it is a permanent hardware issue (at least it was for me). Not due to software/firmware or anything like that. I would get random reboots, sometimes once a week, sometimes twice a day.
I finally had to make use of the warranty and send it into verizon. I got a new one, and it works great! Not a single random shutdown or reboot.

My Samsung Galaxy Nexus won't turn on

First of all I read all the possible posts here in the XDA forum about this problem but no one was able to help me :s
I was listening music with my cellphone than it crashed and turned of from nohting. My first thought was "Damm, it crashed!" and I removed the battery and after a couple minutes I put it back and than the cellphone never turned on again. No battery status is showing up, no leds, odin and flash mode doens't work either. I don't no what to do :s
I tried this:
◘ Unplug from USB, remove battery 5 min, put it back
◘ Odin and Flash mode
◘ Turn it on without battery on pc
◘ Turn it on while recharging
My GNexus model is a I9250 GSM.
Could you add some more details? How long the phone's been in operation, refurbished?, rooted?, your current ROM, kernel, radios, advanced kernel settings such as voltage changes, any tweaks, battery type, temperature.
This exactly happened to me on my DroidX. I spent 2 weeks trying everything to revive it including taking the phone apart before adding it to the pile and getting my current GNexus Toro.. so I know how much this sucks. I'm not an expert on phones bricking but I know that connections can go bad or come loose, especially if the phone has been dropped or other impact, components start to lose their integrity over time and voltage shorts 'burn out' op-amps. You mentioned listening to music, so I'm wandering about the IVA components burning out, which usually has voltage too high especially on boot... Hope you can get it working.

Well first of all I thank you for your concern and my phone is on again, thanks to my uncle. The phone is '4 months old', I rooted last month, bootloader unlocked and I was using samsung stock rom (4.2.1 JB). Yeah, that really suck monkey b*lls. If you got the same problem as me (I really hope not) that's what you should do: First remove the battery, plug the charger and than put the battery back. In my case, It kind "shorted" the battery and my phone is back on. I was reading posts and posts and discovered that GNexus has this problem and a lot. Dunno when it can happen again but I really don't want a paperweight. Once again, thank you!
Glad you got your Nexus back up and runnning. Thanks for posting back with details after you figured out the problem and got your phone working, +1 right there. There's always a good chance this will help out someone later on. :good:
Confirmation: balums worked for me
balums uncle's solution worked for me: specifically, (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button.
Thanks balums!
Does anybody have technical (design/EE) insight into what would cause this?
This was starting from a device that appeared totally dead.
The battery was *fully charged* (and showed up that way immediately when the device finally booted).
I had done the obvious things of removing/inserting the battery, cleaning contacts, checking the USB power connection.
Was about to pull it apart when I saw balums post, saving me huge time.
Device is about 16 months old. Stock OS and settings. First time this has happened.
Search terms:
CDMA (Verizon) Samsung Galaxy Nexus -- SCH-i515.
Phone won't boot. Device won't turn on. Won't start. Dead. No worky.
Thanks,
Seth
Awesome! You trick worked, balums!
Interestingly I also have the standard stock version of OS and Hardware which I bought 14 Months ago (nearly to the day). I was surfing over WiFi yesterday evening and when I turned the phone off I noticed the screen getting grey for a moment, not black. And this morning the Nexus just didn't turn on.
Anyway, thanks for the solution, have a nice day!
That is very odd because my i515 also did the exact same thing and I have owned it for 15 months. I can't wait to get home and try this trick. More to come.
Drew
Thanks!

Galaxy nexus wont turn on or charge.
I tried (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button but my galaxy nexus still dont turn on. i have 4.2.2 stock rooted. i was downloading something and my screen become weird in colors and i cent use the phone. i turn it of and now wont turn on again or charge.
after unlocking and rooting i installed this touch recovery from google play. [ROOT]Recovery Tools
Excellent! balums' suggestion helped me. I thought I had tried this before but apparently didn't quite get this in the right sequence.
The only remaining issue I have now is that when it does turn on, I've got the thunderbolt on the battery indicator, the phone says it's charging at the lock screen, but when I go to Battery under Settings it says that the battery is discharging. This effectively has my phone in a state where I can't unplug it (battery is too low but it also doesn't appear to actually "charge"). I tried replacing the Micro USB charge port PCB board and came up with the same results. To me, this seems like a problem and may indicate a motherboard or battery connection issue. I used the "Battery Monitor Widget" and it indicated that it was getting AC power. Any thoughts?
Thanks to XDA and Balum's suggestion! I thought my phone just died! It was on 70somethign % battery last I looked, connected by USB to the PC and I don't know if I turned it off and walked away for a while or if it turned off by itself, but it would not turn on no matter what I did after I got back to my desk. It is on Android 4.3 takju stock not rooted.
Thank you all again for the instructions on how to revive the GNex!
Samsung Galaxy Nexus won't power up
I got a Samsung Galaxy Nexus. I got it from my cousin and therefore don't have any information about the rooting status as well as the ROM but i guess it was running stock. The phone won't turn ON, it is not detected in the computer. No LED or any other indication. I tried the above method which worked for many people but it failed. What is special about the phone is that the upper part of the screen is heating up more as compared to the rest of the phone. Can somebody help me fix this? Is this a hardware issue?
I have the EXACT same problem as you do. I have no idea where to start to try to fix it. I took a picture, then lines went squiggly across the screen, then it flickered, and died. I cannot power it on at all. I tried Uncle's tricks. No luck.
Anyone have some ideas on what to try? Thanks.

Also having the same problem. My Nexus has been rebooting randomly for the past week or so, and finally, this morning, it refuses to turn on at all.
It's a Verizon Galaxy Nexus running stock, but it's been rooted. I'm using the extended battery. The trick that was posted earlier in this thread doesn't seem to work for me. I've tried multiple USB cables and power sources.
I'm going to try the standard battery when I get home, but I'm not expecting positive results.
Work-around
About two months ago whenever I turned my Gnex off, it became totally unresponsive to all attempts to start again. After a lot of trial and error, I discovered that if I pulled the battery for 30-60 minutes and reinstalled, it would power on normally. I have completely wiped and rooted the phone and the problem persisted.
Today I thought about it some and realized there may be some residual charge in the phone, and my waiting period is to allow the charge to drain. To test this theory, I powered the phone down and then tried to restart - nada. Pulled and reset the battery - nada. Pulled the battery, shorted out all four pins that would make contact with the battery, reinstalled battery, and it powered right up. I have not been able to successfully repeat a fast restart when shorting out all four pins. Pulling the battery and waiting 30-60 mins still works.
Incidently about the same time, my screen has stopped auto rotating (and yes it is set to do so).

Device is about 16 months old. Stock OS and settings. First time this has happened.
Search terms:
CDMA (Verizon) Samsung Galaxy Nexus -- SCH-i515.

You saved my Galaxy Nexus
Similar problem + water
Ok, so I have a similar situation I believe. My phone took a swim. I left it off and riced it. Later on after I believed it to be dry enough, i turned it on. (wow it freaking worked) After a few seconds of using the device checking screen the phone snapped off and went into a reboot. I waited until it came back and i shut it down and thought I'd let it go over night. I plugged it in and let it charge (charge icon was displaying). Everything looked good.
Fast forward. Morning time. I go to turn the phone on. Nothing.
This time the phone won't boot. Instead all i see is the white battery icon show up indicating the battery is 100%. When i plug it in to the charger i get the battery with the charging bolt, then it shows the normal battery indicator light. After that, I get nothing.
I tried the method I saw above. remove power, remove battery, apply usb power, insert battery, press power. Sadly it didn't work.
Anyone have any other ideas as to what might be going on?

[Q] Phone gives no response, but heats. Fixable?

Been coming here a while.. forums are nothing new to meh.. we'll skip the fact I just made this account and immediately made a thread ^^;
We'll get right to the details:
Had her since Autumn last year. Best phone I've ever used. No problems besides freezes I know I caused, etc.. never an issue. Til about October this year. Seen similar issues, looked for two months and found nothing close besides a Nexus 7 that physically needed its battery pulled for it to power on again. Anywho, here's how the moment went down: In the span of an hour or so, my GNex had crashed on me about three times... normally it'll do that maybe three times a day to three a week, depending how hotplugx on leankernel felt that day (having only one core on 90% of the time was pretty sweet). Was running the PA 3.99 based "Built With Love" ROM- the first build to incorporate any Saber stuff afaik- and the flat out 8.0 version of leankernel. Now.. the laast time she froze, the battery was already near dead, so when I popped it back in I plugged it up to the charger. All going as normal, right? Done this plenty from tinkering with kernels and seeing which android ROMs & versions I could hop back and forth to without wiping (had the current said setup for a month straight, surprisingly) Nope. It brings up the charging logo with the lighting bolt in the middle of the battery... and freezes there. Pulled out the cord, waited a bit and everything. Nada. Freaked out, I popped the battery. Went to put the battery back in and power it.. nothing. Okay, maybe that just killed the charge. Nope. Power cord fails to bring up any kind of light or charging animation. No screen activity. Will not boot into odin, recovery, or anything.
The ONLY signs of life still coming from this phone, are heat when it's on the charger, heat after 'USB jumping' the phone -after disconnecting the cord as well, and for at least two hours it continues producing heat- (had to do that when I first got it from Google) , and if I plug her into the laptop via USB WITHOUT a battery, it'll show as "OMAP 4440" for a split second in device manager.
Any more details will come from answering questions. As this happened over two months ago, I'm a little fuzzy on outright recalling details.
Cannot find this problem elsewhere at all. Either it's rare or I suck at looking around.
So I'm coming to you guys. Is she bricked? Stuck in charging.. idk what. Toolkits won't detect a device either, even after the USB jump when I know the battery is discharging and the phone is -technically- powered on.
If you guys could help me out for Christmas, even if it's to tell me she's busted, it would be so indescribably appreciated... <3
[Edit] Nabbed this really quick (attachment). Holding the button combo for download/odin mode has Windows searching this.
No battery inserted, as the dialog disappears and the taskbar pops with a bubble saying "device not recognized" etc. when the battery is put back in or is simply in it when plugged into the laptop.
Also to note: a third party battery yields the same results as the stock one. What kills me is Windows can see it, but aside from that and the heat production, it's essentially dead. What gives? :c
Shameful bump. Need to know if it's completely bricked, or possibly a hardware issue that's repairable or not.
Had to save up for over a year for this phone. Really need to figure out if it's gone or not. If it is, then I'll need to start saving for an N5, which I consider a downgrade ._. Can't beat the community support though, and that extra screen space :3
Aside from irrelevant blabble.. any answer would be appreciated. I can provide any additional information if need be, as well.
Have not seen this issue anywhere.
Bump..? :c
There's almost nothing on charge animation freezes. And what there is, the owner was able to boot their device with some simple workarounds.
If there's anyone who knows what's going on, even to tell me I'm a retard who bricked his phone, please do. Please.
Can't even afford glue to put my shoes back together. Saving up for another phone is impractical this year and probably next as well :\
Would I need the OMAP 4440 driver and some other stuff? If there's some way to push a boot.img to /boot while the phone is in this state, that would fix it..
I'm somewhat sure, at least. Since the kernel's in charge of that from what I understand.. any ideas?
Search for OMAP flash. I think your phone can be revived. i can't search right now but i believe there are some tutorial about OMAP flash of galaxy nexus. Good luck
