dead battery, & thats it...

im running a miui build from abt 2 weeks ago, idk how relevant that is... BUT i let my phone discharge completely til it died. now when its on the charger, it boots to the miui screen, sometimes even the lockscreen, then craps out. i get that the battery is too low to hold a charge, but wat can i do? i tried charging in download mode, but it eventually reboots. custom roms wont allow us to charge the phone while off, so anyone have any suggestions, as i am in this constant bootloop????????

Sounds like you need a new battery, the phone is supposed to shutdown long before there is damage to the battery but a completely discharged lithium battery may never take a charge again, but if you can't charge with the phone off then you may have other issues.
Id hop on Ebay and find a replacement battery. Them work from there

This is my experience i am on miui also and the other day I had the same thing happen and I just did the three button trick to boot into recovery and left it in recovery for about 15-20 mins then reboot and it started to charge. Hope this helps.

Yikes, I guess ill have to remind myself to never let my battery deplete. Although I thought it was recommended to let battery cash in at least once per month.

howd you get it to boot into recovery? when it boots, it goes straight from the circular dotted charging/loading symbol to my miui boot animation, NO samsung screen so i dont know when to let go of the power. ive tried at random times, but no dice. i dont have enough juice to unplug, boot into CWM, then replug

Pull and replace the battery and Hold both volume buttons and the power button at same time.... Phone will reboot, once you see samsung splash screen let go of power button while still holding both volume buttons and cwm should come up.
I Should have said while being plugged in. Mine was via usb

i never got to the samsung screen, but your first suggestion worked. when it booted to the lockscreen, i quickly unlocked, turned off wifi, gps, and adjusted screen brightness, then i wa able to boot into recovery and let it charge a minute... thanks for ur help & to the other the guy that tried

I've had this happen also with a totally discharged battery and CM7. Booted to download mode and wiped with Odin, reflashed CM7.

I had this happen with CM7 a couple weeks ago. A couple guys asked if I was using the actual Samsung charger and pointed out that it has some charging internals that work with a low battery situation that other chargers may not have.
So, were you using the Samsung charger or another USB power source?

(solved-post #7) Bricked phone+black screen

I have been running the new cm9 ics ROM for about 2 days now, and had just got all my data and apps sorted and fully working. I sat down, watched some TV, and after 30 mins i checked my phone. Black screen ( i assume its locked) i tap the power button, nothing, again nothing. I now think i must have turned my phone off. I now hold the power button, nothing, again, nothing. I grab my charger, put my phone on charge and notice no orange or green light. I have repeatedly tried to revive my phone but nothing works. I don't know if its the software, battery, charger, Im so confused. Please if anyone has had the same problem, or has any suggestions, i would appreciate it very much. Thanks.
some extra details: i charged my phone over night the day before, so it shouldn't have died ( i know you shouldnt charge overnight, but i do :/)
i wasn't trying to flash anything or messing around with files, it was in my pocket.
i didn't drop it

Don't panic. Stay calm. The most of our ics roms suffer from reboots or freezes at this stage of development. Your phone simply froze, this can happen with screen on or turned off. If the three button combo (power and volume + -) does not work, You need to wait until the battery drains out.
if you pull the battery there is a chance to freeze your emmc chip and really brick your phone. If you connect the phone to PC before pulling the Batt there's a little lower risk. But I still don't recommend to do so. After your phone is running again, you should overvolt by 25 to hopefully prevent your phone from freezing again.
Ps.
Really, please stay calm, this happened to me about 20 times on ics roms and I'm not the only one.

thanks, i will just wait then, is it normal that adb won't recognise the device? and also two things, how long roughly will it take to drain completely? and when it is completely drained, what do i do? charge as normal?
thanks a lot

1. Yes, if it's frozen adb does not recognize the device
2. Depends on how much loaded your battery was. Could be between 1-12 hours
For me very often it didn't need that long, phone restarted by itself after some time.. (30 mins?) But sometimes I also had to wait long..
3.yes, charge normal
Edit: since your screen is off it could take even more than 12 hours

Nothing yet i think i will have to wait to tomorrow
EDIT: 11:00 am GMT still nothing, it's been almost 24 hours; should I just keep waiting?
And is there any way to tell wether it's frozen, or the Emmc chip is broken? Thanks

Hey, I've been looking around the forums, and it seems to me that my phone's emmc chip is fine. I admit I did, in a panic, pull out the battery and re-insert it, but on other forums people with a 'fried' emmc chip can at least boot their phone, mine is just completely un-responsive, with a black screen and nothing, when you put it on charge. Am I right or could you shed some light on the problem?
Thanks

Seems to me exactly like the freeze I and a bunch of others are suffering from. If you think you can take the risk, you could try pulling the battery.
1. Connect to PC first.
2. Pull battery.
3. Pull USB cable
4. Insert battery after few minutes
5. Try to reboot recovery with adb
As I said there is a chance of freezing your emmc. You might succeed, but you might totally brick your phone too. I'm not responsible, I told you the risk..
Sent by my fingers to your head.

I had a spare battery lying around, did what you said above, instead putting the other battery in and not going on adb, but nothing happened. I think I am going to have to try what you said above ^^^
Oh and once I have put the battery back in do I turn the phone on? It might sound stupid but I don't want to get it wrong :/
Alright a few details:
My phone connected to the computer with a battery in (I don't have a clue how full it is) is not recognised as a 'device with removable storage'
It won't charge (or the orange light won't come on)

Yes, to see if it's booting, I would suggest to turn it on
As I said, try to reboot via adb.
And I would recommend to reboot into recovery and flash another ROM or backup, you don't want to freeze your phone again today, do you?
Sent by my fingers to your head.

I've taken my bay out and am just waiting a few minutes :/

Alright it seemsbe booting, could be a boot loop though
Edit : it's working I'm on the home screen of cm9
You don't know how much I love you right now thanks so much for all the help (I didn't even need adb, it just booted normally 0.o)

Keep your fingers crossed
Edit: glad you already solved it.
You're welcome mate

Or simply do flash a stable ROM. I would prefer this as I don't like to freeze my phone and brutally pull the batt
Sent by my fingers to your head.

I'm trawling through pages and pages of ROMs I think I will stick to stable ones now

If you want sense, try endymion, by far the best.
No sense - reaper, fastest ever.
Just my personal opinion.

I may have not the thread in its entirety..
But did you try VolumeUp + VolumeDown + Power button combination.
Which can often reboot a hung/stuck phone?

[Q] How can I check to see if this is serious?

My HOS is 2 weeks old today. I have rooted it (unlocked BL) and spent many hours with it...kept the stock ROM for now.
I had been using it today and last night and the battery was low so I plugged in the charger (using AC outlet), and left it on. I went back to it 20-25 minutes later and it was extraordinarily hot (I realize this happens...I posted on a thread 2 weeks ago when my phone first overheated to this degree). I saw that like the first time this phone overheated (which was within 48 hours after purchasing it) it wasn't charging. Similarly, this time, the battery showed only ~halfway charged. In my experience, it only takes about 20 minutes to fully charge it... so I was concerned.
I decided to power it off and keep it charging--hoping that the heat would lessen and it would just cool off and charge.
However, I checked it now (perhaps 2 hours later after powering off), and it won't even start. I plugged it in again and waited about a minute (thinking maybe somehow the battery drained), but no luck.
This never happened to me with my last HTC... I have never not had a phone not power up... this seems really weird.
Any suggestions?
Thanks!!!

Mine takes longer than 20mins to charge.....however its not good if it wont even power on, you gotta take it back
Have you tried to power it on by holding the power & volume down button?

Yes, I tried booting into recovery.. No luck... This is so frustrating because I have not really dropped it or got it wet or anything. I don't like the thought that it might have overheated and caused permanent damage.
I will take it back today I guess... Is 14 days still within the return/replace period? I won't even say I rooted it.. Just that it stopped working. Although I will be irritated to have to unlock the bootloader and root a new one.
I am wondering... Is there a way to power up the phone using ADB??
Thank you

unless your phone is recognised in ADB, No !

Well...good news, I think anyway...I tried taking the SIM card out and it didn't do anything so I left it alone plugged in for maybe an hour.
But.....
When I later looked at it, it was on again, and..it had booted into recovery. I had tried earlier to do this as mentioned above, but nothing happened (using power on and holding the volume rocker down:
So after putting the SIM card in it was fine...go figure.
Thanks for the replies!

Am I Screwed??? Please help.

I am running CleanROM 2.1 with the CleanKERNEL and AOSP Blue Mod Theme on my GS3. It is overclocked to 1.70Ghz .It has been working great for the past 3 days or so I have had it set up like this. I took the OTA before re-rooting and reunlocking and before ever putting any ROMs on the phone. I had the phone on my car charger on my way to work this morning, after draining a bunch of battry streaming F1 practice. When I got to work, I pull the phone off the charger and we inside. When I went to check my phone, it was black. And still is. The phone was working fine while on the charger, but now I can not get it to respond to anything. I have tried to reboot, reboot to recovery, pull the battery, and have it plugged in. The only thing happening is the phone becomes warm while plugged in.
I have no flashed anything for 3 days or so. I don't know what could have happened. Any thoughts?? Please help. I am kinda freaking out right now.

So you pulled the battery out, then put it back in. Then held volume up, the home button and then the power button?
What about Odin mode? Volume down, home button and the
power button?
Make sure to unplug the phone while doing this.

This happened to me a few times but with a slightly different scenario. If i tried to power up my phone, it would give a brief vibration and then show me a battery sign with a big 0 on it (green battery image). No matter what i did it wont boot up. And my battery wasn't at 0% when it happened. I was able to get into recovery and restore a backup.
In your case, check if there is any power in your battery (or borrow someone's who has an s3) and see if you are able to boot into recovery.
Hope you are able to fix it. Good Luck.

Then it might be your battery as the other person mentioned. The bettery is either bad or the device is not charging it. Have you tired different chargers as well? It can even be your charging port...
Odin mode and recovery have nothing to do with your ROM when you boot into them. If you boot into that, it boots before loading your Rom.
Go to the Verizon store and just ask if you can try their battery from the demo unti or something if you do not know anyone else with an S3.

There is guy coming in later today with a GS3, I will try his battery when he gets here. I know I was at 99% battery when I pulled it off my car charger. But, I suppose it is possible the battery is fried.

My bet is battery. Put it on the charger for 10 minutes.

Don't want to sound like a broken record, but have you tried keeping your power button pressed for 5-10 seconds? Its weird but the brief vibration I got in my case was when I had it pressed for a good 5-7 seconds and then nothing would happen. Just checking if you have the same symptoms.

This is kinda where I am at. I feel like it is a hardware problem more then a software problem aka not my fault.

So what was the final outcome on this?

This happened to me a few weeks ago. I had my GS3 for about a month. Everything was stock. Never rooted or unlocked.
Its a hardware issue.
If you return your phone to Verizon they will give you a refurb.
I believe the phone gets sent to Verizon not Samsung. Since I wasn't rooted it didn't matter for me, but since you can't even boot into ODIN at the store they won't be able to tell that your phone is rooted so they will order you a refurb straight away.
Its possible that when it gets to the Verizon testing facility they will discover that its been rooted and expect you to pay full price for the replacement. I have no idea.
Good Luck

Sorry for not updating. I ended up getting a replacement phone from Verizon. Looks like some other people are running into the same problem.

So...How did I brick my N5?

I am not inexperienced when it comes to ROMs, rooting, flashing, etc. Been doing it since my Droid X, X2, Gnex and now n5.
So pretty much I installed purity ROM and franco kernel. I was really tired when I was flashing it last night so as soon as I saw it boot up I let myself fall asleep. The last thing I saw was the setup screen asking me what language to select. I woke up this morning and tried to turn the screen on. nothing. held the power button for 10+ seconds then tried to boot again. Nothing. FYI the phone was fully charged last I saw. I have the heat on so it's kind of warm inside. I left it outside on the patio for about 20 minutes to cool down. Still gets nothing. No response what so ever. No vibration, the backlight of the display doesn't come on....nothing. I tried plugging it in the charger, nothing. The battery icon doesn't show up. The backlight doesn't come on. I left it on the charger for about 20+ minutes. Nothing. Plugging it into my computer does absolutely nothing. It doesn't show ANYTHING connected AT ALL. So no fastboot no adb (cant even get to recovery or bootloader) odin is out too. Literally 100% unresponsive.
Didn't think you could do that to a nexus honestly. Especially after all the hackery I did on the GNex. I didn't even do anything funny. Just flashed Purity + Franco (r14) I was waiting on r15.

Try charging it for a few hours (overnight).
I've seen this happen to a lot of people in the nexus 4 section.

Doesn't sound like it had anything to do with flashing anything, especially since you saw it go tot he language screen.
You've tried holding the volume keys while turning it on?
I honestly may have just been a faulty battery in the device. ran out of juice fast and now won't charge or power it.
I'd still try more holding power button remedies, etc.
Not sure that Odin would have ever helped you anyways considering this is not a Samsung phone.
Worst case RMA it through Google..

Yep its happened a few times with people with the nexus 4 too. The battery is at a decently high charge and suddenly it acts as if the battery is dead.
I have seen people fix it by charging the phone for a few hours though. Do you get an LED light when its plugged into the wall charger?

Absolutely nothing. Completely 100% unresponsive. I think it's done for.
Edit: Purchased from T-Mobile, not Google directly. I pay for insurance on the device. Stinks, but I think I'm going to have to file an insurance claim

Why do insurance when you can just do warranty claim at the store? Just take it back to them (especially since it hasn't been 30 days yet) and replace the device.

Did you try plugging it into a car charger in your car?
For some reason that sometimes works. I don't know why, maybe higher amperage or something.
You should try it!

This happened with my Nexus 4, All I did was leave it charging and that worked after quite a bit. At the time I re flashed it back to stock, not sure if it helped or not but I never had the issue again.

OP, have you solve your problem? my nexus 5 just dead when I rebooted my phone. now, i does not have any idea to turn it back on again.
