[Q] Nexus 7 wont turn on or Charge - Nexus 7 Q&A, Help & Troubleshooting

I have read all articles on this forum regarding all issues but none seems to have been of any help. My nexus isnt powering up. When i Plug it in to power, it doesnt show any sign of charging but the back gets warm indicating that power is actually going in. I have tried long pressing for over 1minutes and still the same thing. No response of any sort. I was hoping there should be something that can b done to it like re-running the os like i did my LG optimus when it had the same issue. Please i need help. I have tried all the options of pressing on the site and none seems to help.

Did you check my thread...

Thanks for your response. Really apreciate it. I have checked the battery of my nexus to be sure its well seated and it is. I even changed the battery to a fully charged one and its still the same thing. Since day one it never came on. I have long press for over 2minutes and still nothing. Is there any other thing i can try cus i can send it back to google as my aunt got it for me when she travelled to USA some weeks back and any chance of returning is zero

[Q] It seems to be a "full brick"

Was updating using Odin when, as my luck always proves out, a circuit breaker tripped and cut power to my PC. The phone seemed to be frozen on the "Download Mode" screen (30+ minutes of zero activity) so I pulled the battery. Upon reinserting the battery I discover that the phone is 100% unresponsive. I've tried every trick google could produce for me with the exception of the "homemade jig" method as it seemed fairly clear that the phone needed some semblance of life for that to be effective.
So, my question is... WTF??? I've soft modded wiis, hard modded xboxes, hacked PSPs flashed hundreds of phones and generally revel in futzing around in this manner of endeavor and have NEVER bricked a device (even after some incredibly stupid mistakes). This just doesn't make sense and I haven't seen sysmptoms such as mine presented in any of my web searches. Any ideas???
I'm not saying your not a modder, but you should know to have a UPS hooked up to your dev box, for me its a laptop, so...
Anyway, try removing the battery for 1m, press power button with batt removed, now start up Odin, plug the phone in (batt removed still) and see if the phone connects. I'm sure someone will pop in here and provide links to several threads that describe different methods to help you fix this, I would but I'm sorta busy...

Keep the battery out for like a half hour and then try again. That has worked for some people.
Or try the mysterious button that may or may not exist. I know I'd be pushing the heck out of it just in case.
Thank you so much for your quick input... I tried precicely that 3-4 times (google search turned it up) and it was a futile endeavor.
And yes, I am fully aware of all the proper precautions to take, unfortunately I am also fully stupid with frightening regularity (well, maybe just lazy and reckless), I seem to have become a tad cocky as I have never really had to face disaster before today.
It won't happen again!
plug phone into computer without battery. Then hold power and 1 to go into download mode (still no battery)
That there is what I've seen as most effective thing to work on bricked phone's.
cool... I just popped out the battery and will let you know the result in about 40 minutes...
this happened to me recently, i found a post with the solution being to pull the battery out of the phone hold down 1 and the power button at the same time before popping the battery back in and it will send you to the proper screen to odin back to what you need, worked perfect for me
oh crap I editted my previous post. i forgot to mention go into download mode...
It's --
Remove battery and plug into computer. then go into download mode WITHOUT Battery still.

there is no hole in the back case of my device. I've had my device powered on and bent the **** out of a paper clip trying to push the 'hidden magic button' to no avail.
YMMV (false hope ??)
Cool, didn't know that little button existed!
I bricked mine the same way a few weeks ago and tried every trick in the book over the course of 2 days. It was truly bricked. I don't have insurance; however, my phone was under warranty. Since I couldn't get the phone to boot or anything I figured there was no real way of telling what went wrong. I sent it in for warranty repair and 10 days later, the phone returned in working order. Work order says they replaced the main board. I marked the phone before returning it so I know its the same phone and it works fine now.
And before anyone says anything, I know, I'm an evil bastard. But I figure it's payback for a samsung flatscreen that died 6 months out of warranty.
I've done this, leaving my battery out for 20 mins or so, and leaving it out while going into download mode worked for me. I don't know why but sometimes I can't even get into download mode with my battery in.

it doesn't..
to prove this (or dis-prove it).. go into clockwork and make a nandroid backup (you know, just in case)...then boot normally and while you're looking at your home screen, jam a paper clip in there as hard as you can. Your device will do nothing.

No, it's just not proven. Some people swear by it, some say it's a myth and some say it depends on when your phone was made.

Phone stuck on USB/charging... very weird

Hey there. I have my Galaxy S II (GT-I9100) for about a month, and since a couple of days ago it has been behaving very weirdly about USB and charging.
First of all, the phone thinks it has USB connected at all times. When I go to the settings menu try to enable mass storage it says USB is already connected, even though it isn't!!!
Sometimes when I start the phone it goes to that USB Kies screen and says "connected", when absolutaly no cables are connected AT ALL!!!
When I turn the cell off, remove the battery and plug it back in, without turning the phone on, the recharging battery icon appears, but blinks with a drained battery icon with a yellow exclamation sign and a thermometer which I sincerely have no idea what that means.
It also takes ages to recognize the power charger or when I really connect the USB cable. And finally, when I take them off, it also takes a while to "perceive" they're off and remove the charging lightning from the battery icons.
PRETTY PLEASE, SOMEONE HELP ME OUT, as I don't have time to take the phone to service, and didn't really want to do that
Thanks!!!
This has also happened to me and loads of other SGS2 users! Although usually it only happens sporadically and not constantly. It seems that it's a bad soldering job or dust/dirt has gathered in the microUSB port. You might be able to fix it, if you're *really* careful.

Last night my phone wouldn't even start charging, so I decided to take matters into my own hands. With the smallest screwdriver I could find, I carefully 'lifted' the tiny PCB in the USB jack while blowing in at the same time. Sure enough, some sand particles fell out, and I haven't gotten carmode'd in nearly 13 hours now. Previously it would do it once every 15 minutes. So far so good, it seems.

Thanks for the help... but what is PCB? Is it the connector inside the "hole"?
Tried that and it stopped thinking USB was connected the whole time... on the other hand, it doesn't detect when I connect the USB cable

You can't talk on plural when you only point out one thread. And I've read that, but it isn't the same as my phone doesn't go in "car mode".
My phone's problem only resembled a problem JaX3RiR briefly mentioned in the middle of the thread.
I tried googling it before posting anything anywhere, but couldn't find anything useful.
Please don't try to look like a smartass like that and embarrass yourself. If you got nothing to add to the thread, it's best if you sit out of it. It's much more appreciated when helpful people like JaX3RiR post...
Hi,had the same problem,tried reflashing back to original firmware,but still had the same problem,,the only way i could boot the phone was through recovery mode,(reboot)Had to send phone back for possible repair??cut a long story short they sent me a new phone,,They said they couldnt repair the fault,something to do with the usb charging system,,So i would advise anyone with this specific problem,to send phone back,and get a replacement..hope you get it solved
Thanks mate, I sent mine today as well... I hope they act the same with me, as I'm afraid customer service around here always tries to incriminate the user not to use the warranty...

There is no reason to be angry, I'm just trying to help, and just wanted that we all post in one thread, so it would be easier to track later.
I just posted longest thread. Here is another one if it helps to justify:

I'm pretty sure you have the same problem. Sometimes Vlingo starts, sometimes phone thinks its charging, when trying to boot it shows battery image and won't boot, can boot only recovery and do restart from there.
Get of the high horse when people are trying to help you.
Are you sure you didn't connect USB cable upside down or bended USB port with the cable?
I have no idea what Vlingo is, and obviously I didn't connect the USB cable upside down. I don't think I bended the port with the cable since it still recognizes the cable for charging or booting and going directly into Kies mode, for example.
I am not on any high horse when people try to help me, as you could see my response towards the guys above. Your post wasn't sounding helpful at all, you were just sounding like "hey, you dumass noobie, don't open a new thread for yourself, check the forums first".
By the way, I also took a look at that thread you posted before posting mine, but I have no idea what is "car mode" on my phone...
Sorry if I sounded rough. I thought it is similar issue, so I posted link to longer thread. I had this issue myself.
Peace. Let us know what the service say .
This happened to me one week ago while on holiday....that temp indicator while charging plus the other stuff you mention....
Plus the phone went into flight mode and won't come out....
Got home and did a reset and phone now doesn't recognise sim card...
great phone but I'm a little disappointed

Hello,
Had the same problems aswell, only mine had a bunch of other problems aswell:
When I shut down my mobile it restarts itself and then shows a yellow exclamation mark with an tempgage. Only way to turn on my phone is to connect it with the charger, turn of my phone again, remove the charger and then the phone turned itself on again but without the temp gage.
My phone also thinks its charging when it is not, and when I am actually charging it, its not charging.
Also my PC does not recognize my phone so I am not able to update it.
I have also sent my phone for a repair, I will keep you guys posted.
greets from the netherlands
Yep, mine only got fixed by going into service. It got its mainboard warranty switched.
T- Mobile sent me a replacement phone
They seemed to know the symptoms when I explained what was happening
Same fault for me. Mainboard replaced, works fine now.

How did you guys get it fixed? Did you have to ship the phone out somewhere? How long did you have to wait to get it back? What was the process?
Thanks.
Mine is going to be repaired in two weeks.
I was the 8th SGS2 since tuesday which came in the repair center.
The repair guy said it is a manifacturing fault.
The phone gets hots, and outside temperature is cold, so it makes moisture in the phone.
This cause the phones power management to get fu up (SGS2 has a small battery inside of it, and that gets fu up). Only fix is replace hardware, but 9 of 10 times Samsung gives the fault to the customer. They say it has water damage and can't be fixed in warrenty...
I'm going to write a huge article about it, and I hope it will get published by a lot of site's soon. Phones he admitted having the problem: SGS1, SGS2 and SGSN.
I charged my GS2 2x by USB and it's discharged faster than by the sector
The USB power isn't enough for charge up the GS2 correctly
Are you guys suffering from rapid battery discharging, i have all of the above symptons but my battery drains within hours...I`ve even bought a brand new battery off ebay that is exacly the same issues... I`d like to send it back to O2 but i`ve rooted and flashed custom firmware...

Dead Nexus S

Hi guys,
Tried searching for my problem, but though I found some similar stuff, noone had quite my problem.
I was checking my Nexus S after a trip and it was with the 'emergency only' message. This sometimes happens to me, not sure if it's due to the roaming activation or caused by a bug where the radio subsystem crashes after a long period without network.
Anyway, I proceeded to my common solution: Turn off and reboot.
Except that after the phone was off, it would not turn on.
It doesn't even vibrate. It doesn't show anything when connected to the wall socket or to the computer. It's just completely dead.
Now, I'm not even sure if this is a hardware or software problem. Any idea on how I can debug this?
Here's what I've tried:
1. Take the battery out: no changes (even tried leaving it out overnight).
2. Charge the phone overnight: no change.
Next step: I'll go to a store and try a different battery... meanwhile I'm without my primary phone which sucks... Can anyone help?
Thanks in advance!
Try booting your phone into the bootloader. Hold the power button and volume up button simultaneously.
If it is not the battery, i can see what else you can do, a "dont turn on" phone is a dead end...

Yup, it was one of the first things I tried. No sign of life... I can't get a single sign that the phone is even being powered. It's like the battery was taken out.

Sounds like something is wrong with the hardware then. Have you brought it the store? Might need to get a new one on warranty.
I have the same issue with my old Blackberry 9000. It worked fine up until I stopped using it. Left it in a drawer for a few months. Went to sell it to Sprint. Wouldn't turn on. No LED, no nothing. Worked fine months before when I was still using it. To this day I have no idea what's wrong with it and it doesn't turn on.
Why not get an external battery charger and charge the battery up and then test it?
All true, and after trying with a new battery I'll have a bit more information.
But what strikes me as odd is that I didn't leave it in a drawer - I didn't even let the battery run down... it was just a damn reboot! I shut it down, and then couldn't power it up again (try and imagine THAT happening to you). It would be odd for the battery to be sucked dry all of a sudden...
I have a feeling that there's something else... maybe while shutting down something burned out in the power circuitry....? =S
No one ever heard of anything like what I'm experiencing? It sucks to be the only one!
Thanks for all the help so far, guys!
If you can get to download mode nothing is lost. Just flash new image via Odin.

Never heard of that happening, but it's a possibility... Still, I would first attribute it to a bad battery and try that first
Sent from my Nexus S 4G
With a new battery (that works on another nexus S) still no luck. =(
I still can't find anyone with this problem. I feel like the unluckiest idiot on Earth.
I assume I can't get to download mode since I can't even get the phone to report it is charging (it used to do that even if off). Do you want me to try anything, though? I'm open to suggestions until Monday. Then I'm taking it to Samsung. Hope they can recover my pictures.
BTW, my receipt doesn't have the IMEI and a customer service rep told me I need it on the receipt or they won't give me free support. How can I get it with the phone off?
Regards and thanks to all who responded,
Nuno
nuno, if you cant power on even with a new charged battery, then it's a harware fault and nothing can me done... =o\
but thanks for the advice, i never thought about the data in sd card, i guess i should make some backups! =o)

I've got the same problem: dead nexus s after a reboot. It says "no service" emergency call does not work. I tried pretty much everything like switching the battery, recovery mode, plug it in, etc. I even updated its image to the latest I've got access to. No luck. I'm already contacting samsung to get it replaced.

Did you try flashing a different rom? Or radio/
I haven't experienced this myself but I'm very interested on what happened. Did you guys flash any custom ROMS? or Radios for that matter?
This looks very similar to what i have. I just got my nexus s GT-i9023, it doesn't boot into fast boot, recovery, download mode or normal. The most activity i have got so fare is when i take the battery out, put it back it, and try turn the phone on it will sometimes flash then do nothing. I have looked every ware. When i use "./platform-tools/adb get-state" it returns "unknown". Any help would be great.
What i think i did was this:
- Unlocked bootloader, this worked
- restart
- installed clockwork mod with fast boot, this worked
- wiped data
- wiped cache (correct me if i spelt that wrong, or anything else)
- flashed cyanogenmod, this got an error but i didn't notice it the first time and i can't remember what it was.
- flashed gapps, this didn't work, when i restarted the phone it said that the installer for gaps had quit.
- restarted
- flashed cyanogenmod again, this is when i noticed the error
- restarted, didn't change anything
- wiped data
- wiped cache
- flashed i9020t recovery, this http://forum.xda-developers.com/showthread.php?t=1061855 i think this is what stuffed it up because my phone is i9023
- wiped data after flashing, thats what it said to do, i thought it was strange but i went along with it.
- wiped cache
- reboot
- now doesnt work.
Take it to the store where you purchased and claim ignorance!

[Q] Nexus 7 is dead ... don't want to charge

I tried to find the solution on this forum and with help of google. So I assume people may say ... NOT AGAIN
I have a rooted nexus so warranty is gone. It is 2 month old. I needed vnc so I could start skype remotely so my parents in law (75 years) could see us and we see them. Well the VNC doesnt work so in fact I wanted to put it back non-rooted.
The nexus 7 got completely battery drained (yes I know that I shouldnt do that, but has been somewhere and forgot that it maybe still was running).
I tried all the common tricks what I found:
1. 30 seconds power on button after 12 hours on the original charger.
2. Reset power on/vol up/vol down
3. Fast take out plug and plug in and holding the power button.
No chance. I also can't get to the bootloader. In fact it doesn't wanna do anything. I also tried different power sockets. Used the charger on my phone so to check it is working. I have no chance to get the nexus 7 to charge. It has been charging normally before so I would say that may excluded a lose cable.. to be sure I checked it and all is in place.
Does anyone have any solution or is a replacement of the battery the only option? Can a battery really that easy damaged? Any help would be appreciated.
Make sure to check every fix listed in my thread.
It's a sticky, so everyone has easy access to it in this forum.
Since your N7 is rooted, there may be other variables in the equation not accounted for in my thread.
But in general, the recommended thread lists everything an N7 owner needs to know to bring their N7 back to life, or to get it to charge correctly, or to get the battery status to recalibrate.
Good luck!

Samsung GS5 shutting off

I've got a Samsung Galaxy S5 and I'm having this issue where several times a day the phone just shuts off. I'll go to pick it up and it's not on, and it won't turn on until I plug it in to power and wait for it to show the battery charge display.
I've taken the battery out and put it back in several times, and I followed some guide to clear the cache... EDIT 1: I have also done a factory reset as well.
If I remember correctly this issue only started after updating to 6.0.1 and didn't actually happen on 5.
My first thought is to try and roll back, however is there anything that I should try before this...?
Appreciate any input!
PS: Complete newb with Android.

I've never had this issue with my personal devices but, I had helped a few individuals with their devices spontaneously shutting off without warning.
I've found that 90% +/- of these problems ultimately stems from either one of the following.
1) The Power Button going bad by being worn out, loose or just plain sticking within itself or a worn bezel.
2) The battery beginning to go bad. The batteries going bad doesn't always reflect on the charge itself but, there's actually a small circuit board within them that talks to the device as well.
Out of the 2 above, I've run into more of the battery being the culprit than the power button.
I can't guarantee anything without physically looking at the device but, this is just my view as to my experiences.
Regarding this happening around the time you had updated your firmware, I believe that this is just pure coincidence. It's extremely rare for this to be tied to your Firmware without any firmware issues also being experienced.
I hope that this helps you out and I wish you the best of luck!

I DO NOT provide support via PM unless asked/requested by myself. PLEASE keep it in the threads where everyone can share.
Thanks a lot for your reply!
I'm no expert whatsoever but the power button seems OK from what I can see and feel. It presses in and makes a noticeable click and then pops back out.
I think the battery may be the culprit here. When it shuts down, I can't turn it back on -- removing and re-adding the battery doesn't help. Only connecting power helps.
I think I'll opt to purchase a replacement battery. I have no experience with this whatsoever -- what price should one expect to pay and do you recommend avoiding eBay? I don't want to buy a dodgy battery.

I have very good experience with this battery, I have three of them and they have a very good capacity:
https://www.amazon.de/GadFull-EB-BG...Batterie-Grün-Weiß/dp/B01B80ZWXU?ref=ast_p_ep
Thanks for your replies guys.
I finally got around to replacing the battery (spent $50 AU on it so not a cheapie)... however the issue still persists.
Any ideas what it could be? The issue still occurs even when safe mode is on.
I have rolled back to 5.0. Hopefully this will fix the issue. If not, I'm going to try to root it with a new version.
Any thoughts on what kind of diagnostics I could run to try and figure out the culprit?
(Assuming the issue will persist.)
