Full discharge bootloop - Nexus 7 (2013) Q&A

My daughter fully discharged the tablet. Holding power button or with combination with either volume up or down will only show the empty battery icon and then quickly turn off after 3 seconds. So no recovery or download mode boot. I tried this after 1 hour of wall charging both plugged and unplugged.
Anyone experienced this? What steps did you do to fix this issue.

Not with the N7, but with other devices. I had eventually read in a few thread that the issue was sometimes fixed by removing the back panel, disconnecting the battery terminal clip & leaving it unplugged for an hour or so & then reconnecting the battery, replacing the back & charging (without turning it on or pressing buttons).
From experience with the N7, I can tell you the back is easy to remove & really requires no tool, as long as you can slide a thumbnail between the screen & the back body bezel. Just take caution, like rubber gloves (non-powdered) to avoid static discharge (risk is minimal anyway for most) & to also avoid getting oils on the copper sheeting used in the device for heat dissipation. I had touch screen issues that ended up being caused by a loose ribbon cable, so I have opened mine & I did it without tools & there were no seals I had to break. Take a look at the ifixit teardown for a better idea of how simple removing the back is & for the location of the battery terminal block, which really is right there once the N7 is open.

That's actually the other alternative I'm thinking. But seeing no screw to remove the back panel made me hesitant. I'll try that. Also will look at ifixit for demo.

I've read that one has to leave it charging overnight.

[Q] Galaxy nexus only charges for a few seconds

I have a GN on 4.3, all totally stock. A couple of days ago it stopped charging properly, it now does not charge when powered on. if powered off it will show the large battery icon, then the battery charging animation for three cycles of the animation, the it goes blank, then starts again - the large battery icon then runs through the charging animation three times etc etc. I left it like this overnight and it was fully charged by the morning, I'm guessing in charges for a few seconds then resets.
Any thoughts?!
I'm using the charger it came with, and have tried others but nothing changes. I have had issues with the USB port but have gently cleaned it a few times and its worked fine. There is a possibility that the phone got a bit wet before all this happened, I removed the back and took out the battery and left it in the laundry cupboard overnight before putting it back together, and it was ok for a day.
Love the phone but its kind of unusually at this point, considering buying another battery and external battery charger if nothing else works.
Thanks!
Methinks hardware damage on the phone. Use it as an excuse to buy a new phone

Try to lift the pin in the charging port of phone using a compass needle. Don't apply too much pressure. Just lift it gently a bit up.

The port is obviously going bad. It's not that hard to replace. 6 screws and the back of the phone comes off. Unplug all visible connectors on the motherboard. Make sure you have carefully removed the volume and start buttons that are glued the side of the frame. Remove the motherboard. There is one screw holding down the speaker. When that's removed, unplug the speaker and remove it. The ribbon with the charge port is glued but will come away from the frame with some careful coaxing. Replace it with the new one and re-install the speaker and motherboard. Replace the back housing and you're done.
The port is under $7 on eBay.

looks like lot of people facing the problem right now. was it a self destructible after a fixed period. probably few days/weeks before N5 release.
will try lifting the pin a bit today. it worked for a friend of mine. lets see if it works for me too.. else need to order a replacement port for the same.
Jesus. Mine too. I think google planned it on purpose to self destruct. I actually ordered a new usb port, installed it, and the same **** happens. I don't even know why. I also tried prying the metal connector up a tad with a small screwdriver, still the same. Your symptoms is like the one shown in the following video, correct?
http://www.youtube.com/watch?v=w0ekoZR4VYM#t=31
Yes similar problem. Also my battery indicator on the top right is not showing the charging bolt at times even when the phone is connected to wall charger. If you can see the bottom right battery widget, it is showing as charging.

Yes that video is exactly what happens to mine, I'm wondering if its a software thing. I'll have to get a new phone pretty soon if things don't change.
I guys I have the same problem since 09/09/13. I could charge my phone only from computer USB. But there is a problem, I can ONLY charge the phone if I connecto to the computer!

[Q] Tablet Refuses to power on

Hello XDA members. I have a very troublesome issue with my galaxy tab 3 7.0 inch tablet. It will NOT turn on at all, no battery charging, no device power on, no comp recognition, nothing. I have already tried:
Letting it charge overnight (factory charger along with others) with several known working cables
Unplug battery for 5 minutes
Press and hold power, Vol Down, and home for 10 sec, 30 sec, and 1 minute
Press and hold power and vol down for 10,30,60 seconds.
I sent it in for repair and they wouldnt fix it because it's rooted. When I got it back it briefly turned on to the battery charging, but nothing since. I'm thinking there must have been some way they got it on.... All proper drivers are installed on PC and it's never been dropped, water damaged, etc.
Would anyone be able to provide insight as to why and provide a fix?
My 8 inch tab 3 wasn't coming on either a few days back, I got it back on by holding home and the power button for a while. I was about to give upwhen the battery charging image came on. I think I did the same again and it came on normally.

Was that from computer or wall?
From wall, it was about 3/4 charged by then

Still no luck... I can feel the tablet getting hot down at the charge port so I know it's charging, and i know the lcd isn't damaged.
Mine is in the same condition. Anyone know how or why this happens and how to fix it?

Not sure if this will help, but just like with phones, sometimes android tablets just need a battery pull. My kids xo tablet went dead and before I tossed it in the trash I took the housing off and had to clip the + wire since it was soldered to the board. Twisted it back together to check and sure enough the tablet powered on like normal. Ive had to pull the battery on an Sm-t217a and it was a lot easier. They have a removable clip that attaches to the board.

I think it might be the battery itself. Just for giggles I left it plugged in for days and i just checked back on it and the Battery charging screen kept flashing on and off. Won't hold any charge. Probably will just order a new battery and see what happens. I pulled the battery a couple times and nothing happened. Closer inspection found that the tech that looked at it damaged the battery cord (unless it came with the copper on the wiring already exposed...)

You might be right about the battery being dead, although they usually don't just go all at once like that. The charge indicator flashing is odd. The only thing close I've seen is an "x" over the icon when there aren't enough amps (my tab needs 2 amps. 1 amp chargers and some pc usb ports give me the x.
If you have an old cable you can cut, you could try to charge the battery itself to see if it takes a charge (or at least use a multimeter on it to check for voltage). Then you could narrow it down a bit to whether it is the battery or possibly the charge port/hardware..... I saw a bit of exposed wire just before the clip of mine too, made me extra careful pulling the clip up.

I wouldn't even know where to start with the wiring. Multimeter isn't something I have access to, and it seems a little complicated for me to spend time on.
When I say it's flashing, I mean the device powers on to the battery charging screen, then dies, wash rinse repeat. If I go into recovery, same thing. It all happens within a couple seconds, so it's hard to describe.
My dad has one that I can pull the battery from, I might do that. Batteries are like 20 bucks on amazon, so I think I'll test with my Dads and if it works just order a battery and report back here.

My daughters tab 3 7 inch T210 also refuses to start. First time it was fixed by opening the device and disconnecting the battery. Now that doesn't help anymore. If I attach the original charger and measure the voltage when the device has rested for some months I can see that the voltage slowly rises so it seems to do the charging even if there is no sign of charging on the screen. After some hours of charging I measure 3,78V on the battery, after disconnecting the battery.
If I attach the battery and turn on the device I measure 3,76V before I push the start button and 3,74V directly after pushing the button. After about 15s the voltage goes back to 3,76V. Nothing happens on the screen... Tried with different combinations of pushing on-button and volume up, volume down, menu....
So -the best thing would of course be a quick visit to local shop to buy a new device of another brand but for some reason I refuse to give up.
Any advice would be appreciated.
(I Have made no significant modifications but the 4-year old daughter may have contributed in an unknown way )

The better way to test if your tablet can turn on: buy a new battery, under $15 on Ebay since your old battery is dead or completely drained.
Use the new battery to turn on your tablet. If it's on, check the build number of your device after go to About My Device: if it's not end with OB1, the latest firmware which fix charging issue.
It's more likely your build number is MK1 to NI1, the build numbers count by alphabet order. Upgrade the software via Wifi, battery must be at least 25%, otherwise your tablet won't allow you to upgrade. Bring the firmware to the current OB1, your tablet should take charge normally, otherwise the USB charging port is defective or damaged. This micro USB is cheap, around $2, but it need to solder to motherboard to replace the defective one.

hardware issue?

My phone won't boot unless it is plugged in via wall charger.
If I got it to boot while charging, it instantly turns off when I unplug it even with battery at 100%.
I am able turn to go into hboot mode(power + volume down), even when it is unplugged. But it dies if I access recovery. I am able to perform "show image crc" function.
The problem started while I was using the camera and it just turned off by itself.
I was on SROM at the time when the problem started.
I managed to change ROM to SD, and even used lollipop RUU(verizon), but the problem wasn't resolved.:crying:
What do you think? Am I right to assume this is a hardware problem?

I have same problem!
Bump. I have the same problem too. Seems to have come out of the blue for an otherwise functional phone. Can't figure it out.
I'll add that I can get into twrp and it seems to function without the charger plugged.. But otherwise, if the charger is removed, phone dies like OP.
Anyone can help?
Hey, this happened to me too while I was using the camera too! What's the linkage?
@yakultski, have you figured this out yet?
Try to flash a RUU and if you got the same it should be an hardware problem...

Did you resolve the issue. I heard it could be the battery failing, but i'm not so sure anymore, because when i run antutu benchmark my phone shuts down when using fisheye image processing or 3D, it turns off even when it's plugged in.
I suspect it's the GPU failing or something similar. That is weird since i wasn't using any intense 3D games. I'm sure this is my last HTC.

I don't know if you managed to solve your problem, but in my case I replaced the battery and now the problem is gone. So defective battery is the reason in my case. I replaced it my self which is quite a task but not so hard, you just need patience and time. So if you have time to reply me, please do, as i would like to help.:good:

Hey Gunman84, my phone is behaving in a similar fashion as the OP. I have an AT&T phone converted to a GPE. So everything is stock in that sense. If plugged in, phone operates normally. As soon as I unplug it, a couple of seconds later it will power off. If I boot into hboot, the phone will stay on for a long time (its been an hour+ already and its still on).
I watched a youtube video showing how to replace the battery and that was pretty intimidating - haha. Where did you get your battery replacement? and how much did it cost?
thanks

Hi, it's not so intimidating . Well you just need to be careful and patient, there are lots of small resistors, connectors and so on. Check the iFixit site for proper instructions here is the link https://www.ifixit.com/Teardown/HTC+One+%28M8%29+Teardown/23615 this is full teardown, and here is 2nd link where they focus mainly on replacing the battery https://www.ifixit.com/Guide/HTC+One+M8+Battery+Replacement/41650. I'm from Slovenia, and the battery cost me 20€, which is around 25US dollars, the battery was original one. I bought it from local supplier. It took me around 2-3 hours to replace it, or something like that, that's because i wanted to be careful.

Thanks so much for the links.
The phones behavior really makes me question if its the battery. For example, it stayed on in the hboot/recovery screen for 10+ hours (without being plugged in). So the battery can definitely hold a charge.
I'm afraid to open up the phone (and potentially break it), when there is potentially something else going on (maybe a software issue). I guess if I run out of ideas, I'll have no choice but to attempt the battery replacement.
thanks again!

Well in my case i could also stay in recovery mode(TWRP) indefinitely also in bootloader mode, that's because you are not in the operating system. The graphics are not running at that point and so on, it doesn't drain that much power at that point either.. It's a different story if you try to flash a rom in aroma, at that point the phone shuts of if not plugged in. It is the battery, trust me.

Really appreciate your responses. Makes sense what you say. I'm going to attempt the battery swap. Got no other option!
For the adhesive parts of the phone. When putting it back together, did you need to reapply more adhesive?

Nope, no additional adhesive was needed in my case. I used the hair dryer to soften the original adhesive. The speaker grills were difficult to remove as they are glued quite well, but eventually they came off. The toughest part was separating the back casing, as you do need quite a few prying picks or guitar picks.
Just be careful with the motherboard, slowly remove the tape that covers the connectors, you don't want to rip apart any flat cables. And don't throw away that tape, you will need it.

Well if yours symptoms are the same as clemdaddy has, then yes. Sorry, but at least now you know what the problem is.
Got the new battery today and performed the phone surgery. All the connections looked good. Pieced it all back together and everything works BUT the new battery won't charge. The phone is running off the battery, so the connections I made must be correct. Running off the battery the phone no longer exhibits the symptoms I described above (so this most likely confirms my previous battery was the culprit). I tried the hold all buttons for 2 minutes to re-calibrate the new battery. All that did was made the phone now display a full battery (instead of the empty battery it initially showed).
On the weekend I'll open it up again and see if I missed something.
Got the replacement battery. Re-opened up the phone. This time I over heated the upper and lower panels which caused them both to warp a bit, and one of them to have its paint bubble :crying: :crying: :crying: :crying:
I replaced the new defective battery with the most recent one. Put the phone back together and it is back to normal again! Also probably because of the over heating, there is now a little bit of a rainbow effect on the lower part of the LCD screen!
A real pity the first battery was defective, causing me to have to re-open it and carelessly overheat it. Otherwise the 1st attempt would have been a flawless repair!
With the warped panels, the bubbling paint and now the rainbow effect on the screen, I wonder how long I'll keep the phone. These little things are definitely bugging me... If I get rid of it, I'll really miss my google edition htc one m8! Nothing like a nexus like experience with a remove-able microSD card. Such a thing no longer exists

Nexus 7 Gen 2 won't turn on

Okay, here's the story. My Nexus 7 Gen 2 went into the water for half an instant. However, when I tried to turn it off immediately, it wouldn't turn off. I put it in a container of rice for a couple of days and eventually, it turned off - the battery died, I'm sure. Anyway, now, when I plug in the charger, I get the battery charging symbol, however, it will still not turn on. I've tried some of the button combos mentioned (hold power for 30 seconds, hold power and volume up for 3-5 seconds, hold power and volume down for 15 seconds, even hold power for 2 minutes), yet nothing seems to work. But as soon as I unplug it and plug it back in the charge symbol appears. Any suggestions?
Thanks!

If you put the tab in the rice container without removing the back, you don't know if all the moisture that seeped in has been removed. You need to disassemble the thing, dry each and every component inside with a blow dryer ( both sides of the electronic boards) to make sure of that. Thereafter, you can try again. Because even if you succeed in flashing the OS anew, you'll never know when the residual moisture will interfere or affect the components again.

I didn't use a blowdryer, but it sat out on a table with the back off for about 24 hours and I do live in southern Colorado in the high desert, so humidity isn't a huge factor. I may give that a try today, though. Thanks.

I'm afraid some corrosion has set in already and it may not be reliable anymore.
Next time, you should immediately disassemble it and disconnect the battery, then use a hairdrier to remove the moisture ASAP.

I'm afraid some corrosion has set in already and it may not be reliable anymore.

So, given that it will open into the reboot screen and the volumen buttons seem to work but the power button itself doesn't work, could it be possible to replace the power and volume buttons and get it to restart? Just wondering if I can manage to salvage this thing.

Yes, try to replace or test with multimeter the control buttons assembly first but if it does not help then remove the motherboard and its shields, and check it for any visible signs of corrosion. Scratching off a conductive corrosion layer may fix it.

Battery too low. Charge for a while before powering on

Hi,
I just installed a new battery into my OnePlus 3, because the old one was starting to bulge and push against the screen.
After installing the new battery and attempting to boot with the charger plugged in, the phone won't boot past the 1+ screen.
It buzzes, shows the 1+ screen for a while and then goes dark and buzzes again etc. If I pull out the charger cable it goes dark instantly.
If I hold down the volume down button and the power button for 30sec it boots and shows a warning screen saying "Battery too low. Charge for a while before powering on". However, this screen only shows for a split second before going dark again.
I added a photo of the same screen on a different phone that I found online as the screen really disappears within a few milliseconds on my phone:

Does anyone know what this means? Is the new battery faulty and should I return it? Is there something I should do to reset something? Can it be that it is simply not properly connected?
Any help is welcome! Thanks
you should leave the phone and let it charge until 100%

I let it charge all night, but obviously it is not charging...
is there anything important on the device
Just opened up my phone to put the old battery back in and that's when I saw that the connector had gotten loose. :silly:
There were some small pieces of tape on the original battery's connector that are supposed to hold it in place, so I fabricated my own out of Scotch. Hopefully that will hold the connector in place.
ok get back to me because i want to know if you have solved this
