So last night at kickball, I sent a text to my wife. The next game, I wanted to see if she texted back, and my phone was off. I didn't remember the battery being low, but thought that perhaps it might have been. When I got home I plugged it in and got nothing. I tried to do the Power/Camera/Reset to see if it would go into bootloader; again nothing. I left the battery out all night, put it back in this morning, still nothing. I've tried usb charging and wall charging as well, with and without the battery. Nothing turns it on... is it done for?
Same thing happened to mine recently. I know the battery was low, and it turned off because of that. Never got it to turn on again.
The only sign of life mine shows is that the red led will turn on if you have it plugged into a charge with the battery out. Other than that, it's a paperweight.
Never got mine working again.
I took mine apart, and somehow got it to turn on again... it was a messy process.. something must be shorted out. Going to have to get something new soon.
i have just the same issue with moto milestone ... i am sure that the battery is fully charged, cause ive charged it with another milestone ... but that one simply won't turn on ... tried different combinations of sd/simcard/battery on and off .. still the same ... Any help would be highly appreciated.
same issue here, mine just stopped working yesterday, battery was fine, i did a soft reset randomly, and then it wouldn't turn back on. Both the talk and end lights are on, that's it..
Mine does the same thing since it was dropped in water. It had'nt been turned on for 2 years since I decided it would work! It still does the red light thing sometimes, but all I got to do is remove battery, try power button and repeat the process until it works. Try it out!
On my TMOUS HD2 I am running a build of Desire 2.2
Its been working great for the better part of a week.
The only kind of problem I have been having with it is when it dies, I would sometimes need to pull out the battery before it would once more charge.
But that really wasnt a big deal for me, my thinking was, well i'll just start charging it before it dies.
Last night I was up playing angry birds and the battery became pretty low, so I called it a night and I pluged it in to my Chome Notebook for an over night charge.
When I woke up this morning my phone will no longer turn on.
My first thought was my notebook lost power and in turn the phone never charged, but that wasnt it.
The I thought maybe the notebook didnt send out enough power to charge the phone ( I have charged it through this notebook before ) so I plugged it into the wall and the charge light just blinked... almost as if it had a full charge.
I went to boot it up and it only flashed my boot screen before shutting off again.
After I repeated this I would eventually get to the MAGLDR, but right after it would shut off.
I took the battery out for about a minute this next time and I was able to boot all the way to the DFT screen, but it shut off yet again.
I checked to see if I could get into the bootloader screen, and I could, but it still shuts off when I get in there.
So currently.... I have it with the battery out for another half hour before I try booting again.
Ok, its been 1 hour now I put the battery back in. When I pushed the power button it didnt do anything. But when I pluged it in, it turned on to the boot screen and once more turned off.
But a few seconds after that the charging light came on.
I am going to leave it like that for a bit and see where it gets me.
Right now, I have it charging from the wall. I will leave it there for an hour or 2.
haha, any ideas?
atm you can't charge the phone with magldr installed when the phone is off.
hope it helps
I don't believe that is the actually problem.
I had left the phone on the charger for the past hour and a half and just started it up, and to my surprise it loaded all the way back into android and showed that it was actually charging.
I guess.... maybe it was slowly dieing over night because it was not getting enough charge from the notebook.
And when I woke up and check my phone it was so drained it couldn't even boot past the boot screen.
HELP,
yesterday, I was using my nexus 7 for normal use, wasn't playing game, just browsing with chrome. the battery was 8 percent when I last saw it. I then proceed to charge it, but the thing suddenly just shut down itself. I thought I misread the battery percentage, so I charge it anyway. about an hour later, i checked on my nexus 7, turn it on, got to the boot screen, got to the home screen, use it for about 15 minutes, and suddenly, the screen black out, it was flickering like crazy, and making some white noise ish sound. I panicked so I hold down the power button and turn it off. I turn it on again, and after about 30 seconds, the same thing happened again. I was using motley's kernel with 520 GPU, and I thought, maybe my nexus 7 cant handle the GPU OC. So I went to recovery, tried playing with recovery for about a minute or so, but the screen didn't flicker at all on the recovery. So I flashed the 484 GPU version of motley's kernel. When I reboot to system, the same thing happened again. So I thought, maybe if I restore to my old backup, it would not be like this any more. so I wipe the data, dalvik, and cache, and I restore my old backup. But the same thing happened again, only this time, after I turn it off, it make a high pitched sound.
I waited for about 6 hours, and now when I turn my nexus 7 on again, it works normally.
So, what has happened to my nexus 7?

I'd say it is the overclock. Graphic cards do some weird stuff when overclocked. You can burn up your GPU doing that and cause it to forever freak out. I always shied away from GPU overclocks.

would that cause any permanent damage?

It should be ok if you reflash back to stock rom to make all the hardware back to reset mode. A warning always given when we try to flash rom with oc created.
i also experienced this one, also received a battery warning and then suddenly screen went blank. then same weird thing happened as the one above. I'm on paranoid android rom and i'm quite sure it's not overclocked or something. Was only able to get back to normal by holding the power button for around 15-20 seconds...
Happens to me
This will happen to me a lot when my nexus 7s battery dies, I plug the tablet in and then immediately try to start it up. It will work for around 30 seconds then look like an old TV without a signal. I am on stock everything, no rooting or custom Roms (yet). I always thought it had something to do with battery calibration being off and the tablet not having enough power to run, because it always works fine when I charge it before attempting to boot.
I have also noticed that every once in a while the screen will have a vertical line of pixels flicker.
Same thing happened to me yesterday...
I got the "low battery" warning and after some time the screen started flickering in many colors and there was a weird static noise.
I pushed the on/off button, but it wouldn't turn on again. After a few minutes of charging, I could turn it on again.
This isn't normal behaviour, is it? Shouldn't the N7 perform a regular shut-down when the battery has no juice left?
I'm on the rooted stock rom btw.

I faced the same problem. I dont know when the battery might have drained out, but on starting the tab on low battery, it suddenly started showing black screen with little grains and suddenly stopped with a noise. I charged, started the tab again while charging, and the battery reading stuck at 21% even after charging for 20 mins. Within 5 mins, it happened again. Now after 35 mins of charging, I start it again, it boots normal, and now its reading the battery percentage in an incremental value (started with 22%) and now its again stuck at 23%
Is this a HW related issue? Or do you think it is more of SW related issue? If it is more towards the HW side, we better have it replaced. Mine is C70 model.

just happened to me... it may have run out of juice... didn't turn on when I tried, so I guess it did... then I put it on the charger, tried booting it, went away for a sec and when I came back I also got this black screen with some flicker and a static noise...
will now try to charge it over night before trying again...
Nexus 7/Google problems
I received my Nexus 7 on Aug 21 after hearing the rave reviews. It didn't come with app for a camera, so I downloaded one.
The camera didn't work. I re-booted it & it worked this time. Downloaded Skype - whole reason for getting the tablet - to stay in touch with family that is far away. Tried to Skype - camera wouldn't work. Rebooted - worked this time again (getting tired of having to reboot for something I want to use to work). On Sept 2, sent message to Google inquiring about camera & app I downloaded. Only response - "thank you for contacting...blah, blah, blah - check out Q&A." All along, the tablet would shut itself down & reboot randomly (battery fully charged sometimes). On Sept 13, I shut it down & charged it. After a full charge, I tried to power it back on. Tried again several times that night & then the next morning. Called Google (who I bought it from). Told them I didn't want a piece of junk that wouldn't work. He told me it was past my remorse period. (The only remorse I have is buying their piece of crap instead of a reputable one.) I finally did get it to come back on, but camera hasn’t work since even after a complete factory reset. Any way – in order to get this one fixed, I have to “buy” a new one, then send back the old one & be reimbursed. Is this a legitimate business practice?
hi,
since today i have the same issue. did nothing special, just swichting from g currents to chrome. stock rom, no modifications, not rooted, everything original
n7 suddenly had a black screen(battery was at 28%). nothing worked, no powerswitch(10-30 secs). when connected to original power supply and cable, it boots up.. google logo .. glowing X.. lockscreen. then, approx. 30 sec later it turns off again(screen black). usb cable still connected. after some time it comes up again.. and repeats the procedure. after some cycles it stops, and when i reconnect the usb calbe it starts over again. sometimes, before it turns black, it shows a flickering screen and sometimes fizzling sound.
any suggestions?
I had this same issue right after the 4.2 ota update, after leaving it on charge overnight it seems fine now after a couple of discharge / charge cycles
Its like after the update it was over estimating the battery level

Same thing!
I have a completely stock Nexus 7, and the EXACT same problems are happening to me too! The first couple of times it happened my tablet would reboot normaly. But now, my tablet won't boot up at all. Any suggestions on what I should do? Also, remember, I have no mods installed.
Happening to me too.My N7 shut itself down because of low battery a couple hours ago and I haven't been able to get it to boot since. When I plug it into the charger it shows a flickering screen like a tv with no signal but with less white flickers. I've tried multiple chargers and cables but I could only get it to boot up a couple times and both times it did not show that it was charging even though it was plugged in and the battery was at 0% so as soon as it boots up it shuts itself down again because of low battery.
So now I've got it on the charger, screen all a'flicker, waiting for it to get a charge but I've got a feeling its not even charging because, like I said, the few times it has booted it showed the battery at 0% and not charging.
I guess I'll try to leave it alone for a while and see if it will start up after being plugged in for a bit.
EDIT: I let it sit there and charge for about an hour or so (with the screen flickering) and I was finally able to get it booted. It said it only had 3% battery but now it seems to be charging as fast as usual.

Yup... I've let mine sit there turned off and charging over night... helped!
Just had a problem with the Nexus 7 not charging when battery was likely fully depleted. Putting a charge cable in was automatically booting the Nexus 7 up and wouldn't charge shutting down right after. Loops going on and off. What I did was plug a charge cable in and hold power+both volumes and now I believe I am charging at the bootloader screen. It stays on so I will leave it like this and if it doesn't resolve the issue I will try recovery once it is charged.
I've just started having the same issue. Has happened twice when battery gets to 8%, suddenly jumps to 0, shuts down, then after a few seconds restarts itself. Gets to home screen for a few seconds, battery showing 8, then jumps to zero, switches off and has flickering blocks on screen with static noise. This keeps repeating, only way I have found to solve it is to load into bootloader, then select power off. Device charges normally then and once charged works fine. I am unlocked and rooted but running stock 4.2.1, think I'll just have to return it for a warranty claim.
Based on what you experienced, the lesson here is your device can't handle the GPU over clock of more than 446mhz or it will do some crazy stuff.

So I've had my Moto X Pure (XT1575) for almost two years now, and it's been through hell and back with me. A few months ago, I replaced the screen because of the hot spots the screen had since I've bought it, at the same time, I replaced the battery, the frame and installed a wooden back cover. Yesterday, while I was using it, the phone died and started trying to boot itself back up. I thought it was a sudden turn off, like when you have 30% and it dies because the battery is old. So I let it in the charger for a few minutes just so I could turn it on; but it didn't, it turned on for a split second, showing the bootloader unlocked screen and dying instantly. Luckily I managed to boot it once, and what was weird is that the battery showed 50%+ charge and was charging normally. I went to sleep and let it charge overnight, now it flashes the white led as if the battery level was too low to turn on. I suspect it's a bad battery, but maybe it could be something else. Any help is appreciated.
UPDATE: I've tried to boot the phone again but it doesn't want to do it, it just flashes the bootloader unlocked screen then dies, it's like a bootloop but weirder. Tried to get to the fastboot menu and it lets me, it says "battery is low" in the battery status, which is weird, since it said "battery OK" yesterday.
NVM, I opened the phone and disconnected the battery and put it back on and the problems fixed itself
Hi!
The phone was working fine up till yesterday.
I left it charging, only to find it stuck with the red LED on. It would not respond to button presses, and the LED stayed on even after being unplugged.
I took the battery out, put it back in, didn't want to boot. I took the battery out again, left it out for a few minutes, it booted with an unfamiliar message "Could not do normal boot" or something along those lines. After a restart it booted normally.
I used the phone normally the whole day, but after leaving it charging, same thing happened, but resolved it with leaving the battery out for a few minutes.
Phone worked fine from there on.
Left it charging before bedtime, found it stuck again in the morning, but this time, no way to boot.
I changed batteries, left it without battery for quite some time, nothing.
The phone is rooted, running a custom ROM, flashed sometime last year. Had no problems until now.
What do you recommend?
Seems like it could be the eMMC error.
I was extremely unlucky and it died completely in just one day since the error manifested
If you have any suggestions on how to revive it, please share!
I tried cool it in the freezer, didn't help
Note 4 won't charge or boot - Fixed
Hello,
My note four recently started running sluggishly and the battery would only charge to 77%. I rebooted it and it was now stone dead, would not charge, boot , nada. This is the fix I found that worked for me:
Take out battery, sim card, and mem card. Install back cover. Place phone in ziplock sandwich bag and seal. Place bag into freezer for 20 minutes. Remove bag/phone from freezer, reassemble battery, sim and mem cards. Press the start key and phone should boot(mine did). If not, plug into Samsung fast charger and try booting again.
Regards
