Nexus 7 screen flickers and does not turn on after battery ran out after water damage

About 3 weeks ago I noticed my nexus 7 charger or charger port inside the nexus (more likely) was faulty and I was having to physically put fore on the charger to bend it downward to charge.
This was fine, however since then about 4-5 days ago I dropped my nexus 7 into a shallow sink of water. (about 10-15cm). I removed it immediately and dried it, disconnected the battery and left it in rice for 1.5 days. I then reconnected the battery and noticed it automatically tuned on. There was a small smudge on the top of the screen, and the power button on the side did not function.
I put it back in rice for another 2 days and then found the smudge had gone, but the power button still didn't work. I opened the back cover of my nexus 7 and noticed the track joining the volume up and power contacts was slightly broken, possibly from water. I was and still am likely to try to fix this by applying some conductive paint over the affected area. It is worth noting that I used it for several hours, and the device worked fine aside from the power button and charged normally
Because the power button didn't work I did not want to get my nexus to dim the screen and lock itself, so I turned off sleeping in the settings. However, this then depleted the battery and it must have turned off when I left it. I plugged it in and because I'm guessing the nexus somehow detected the power button wasn't working, turned itself on as it had done before, however it then shut down because there was no charge, and then turned on again, and then turned off... (only when plugged in)
I realised this would be happening all night, so I opened the boot menu by pressing the volume down key during the nexus 7 starting up, and left it in that screen overnight hoping it would let it charge. However in the morning I realised I couldn't exit the screen because one of the controls was the power button so I disconnected and reconnected my battery. Now this is where I am currently at, there is no activity when the nexus is not plugged in, so I do not think the battery has charged, and when I do put the charger in (and I have to hold it down to physically bend it to charge) it now has a black screen with random white fuzzy pixels and no activity.
Please help!

i thought this thread was a joke lol
dude you may as well just finish the job and run a truck over it :good:
try getting another battery , fixing the power button, if your get more problems just accept .....you killed it lmao good thing they're only £190

Hey Chris, I had a similar issue. The unit was water damaged and went into a continuous loop of turning itself on and off. I eventually also put mine in a bag of rice and took it out after a week to realize the power button was probably damaged and kept looping itself in that cycle. Each time when I plug the device into a power source, it just turns itself on, gets into the OS and then turn itself off again because there wasn't enough power.
I ordered a power button strip on ebay for $10 and tried to install it into the unit. After the installation, I was able to charge the unit (ie: when i plug it into a power source, I can see the charging icon come on and after a day it was fully charge. At the same time, the device didn't keep rebooting itself).
Now that the Nexus 7 is fully charge, whenever i reinsert it into a power socket, the icon will say it is fully charge. When i press the power button however, it won't start up. This is where I am, also stuck and don't know what to do.

[Q] Replaced LCD, phone won't turn on

Hi, I just replaced my broken LCD but now it won't start. I'm worried I might have damaged the battery and I have damaged the logic board. The very little black thing pointed with an arrow in the picture below is hanging by a thread.
Symptom :
When plugged in USB, the red light flash constantly
Screen does not turn on, no vibration
If I unplug the battery and plug the USB nothing happens
I'm trying to diagnose wether it's the battery or motherboard or both that are broken
Question :
Should it start with the battery unplugged (it does not)
Should it start with a broken battery plugged
Do you think the little black thing I half broke can prevent it to start
Now that the screen is not broken, can I get the rest of the phone fixed by the warranty or they will be able to tell I opened it
Thanks !

No its not ur battery. The red light issue appears with nexus 4 a lot especially when your battery drains out to 0%. Let it charge for couple hours.

I ended up transfering the internal from another nexus 4, and it did the same thing. As you said, after charging for a while it started normally.
Although I still can't tell if the first one is working, I'll have to reconnect it to a broken screen and see if it boot after charging for a while because I forogt to do a nandroid backup of this one

[Q] Nexus 4 battery woes

Hey guys
I just had my digitizer and LCD replaced. My battery appeared to be damaged when I ripped it out, and the back cover was cracked extensively from the drop.
I got the phone back from the repairer with just a new screen/lcd in it, who said he had troubles powering it on. I got it home and charged it for half an hour and it would get to the google circles spinning and it would cut out and go back to the charging screen.
I ordered a new battery and installed it this afternoon, about an hour or so ago.
When I plug the phone in to the power, the light flashes orange for less than a second and it stops. No buttons are responsive.
If I hold down the vol-down button and insert the micro usb, it goes to the bootloader menu and stays there. If I select start it shows the 'Google' screen then cuts out and the light flashes orange once. If I hold vol-up when inserting, it shows the battery charging icon for a few minutes and then cuts out, and when it does the light flashes orange once.
I've left it sitting for about half an hour now and it's still not responsive.
Anyone have any ideas whats going on before I put the original battery back in?

Put the old battery back in with the same results.
What the hell is going on :/

Battery or Mobo, opinion please!!

Replaced the LCD full screen assembly on my LG G2, all went smooth following a YT video couldn't really have gone wrong,
Switched phone on and battery displayed 0% for several minutes, eventually getting to 2% when I turned it on, all was still OK, however it dropped to 0% within a few minutes even while still plugged in,
Then it was completely dead, no charge light and couldn't turn on,
Removed all of the components again from inside of phone and rechecked all of the connections, again all OK, this time it cam on again!! 0% charging, so I left it charging waiting as long as poss, 45% it was at when I checked but left it while I was sleeping,
Woke up this morning to phone completely dead, cant power on and no charge light showing
Am I wasting my time buying a new battery? could this be another component? LCD?
Appreciate any help,
Thanks
Lee

have now disassembled and re-assembled a further twice and now it does not power on at all
no red flashing light and nothing on display

I've got a similar problem. Did you find out anything? Bought a replacement screen from ebay, and was really confident I could do this, since I earlier replaced the usb charging port with no issues. Of course the battery was discharged completely before this, but I charged the phone and it worked a week ago (which resulted in an annoying alarm that I was unable to shut off because of the broken screen). So after replacing the screen, I plugged it in and turned it on before putting on the back cover. At first it vibrated and I could see the backlight turning on. Then I could see the red led, and thought it was charging, but then the led started to cycle between different colors. I was not able to get a picture on the screen. I then plugged it out and put on the back cover, in case that was needed (didn't seem so from the yt video I used). After that, nothing. Not even a LED. And the phone didn't get any hot like it does when charging/working. It did somewhat get a bit hot the first time.
My first suspect was the battery. It did take some wiggling and force/heat to remove it‚ and it did kind of bend at the edges, but not very much. Any ideas?

Battery is fully discharged and doesn't charging - only access is to Fastboot

Hello,
I wasn't using my Moto X Style for some time. I've took it yesterday, and it has a problem with loading.
Battery is fully discharged. I can't turn on my phone.
When I plug phone to charger (I've tried 4 different charges, with different cables), screen is blinking - white screen with battery icon on it. It's showing for around 1-3 seconds, turn off, and again. I left it for whole night, but it doesn't help. Still nothing.
I can get into Fastboot. When I choose any option like Start / Reset Bootloader/ Recovery Mode etc. is showing white screen with Moto logo, than turn off and screen is black, after that I can't get into Fastboot mode, I need to unplug and plug cable again.
I've noticed, that when I get first time in Fastboot mode, I saw red information "Battery is low". Now, after my trying to turn on the phone, there is green information "Battery is OK"
When I left telephone in Fastboot mode, it restart after some seconds, and start blinking with white screen and battery icon.
Any ideas how to turn it on?
I saw in internet one option, to disassembly phone, cut USB cable, and put (+) and (-) wires directly to battery to load it. What do You think?

It sounds like your battery may be completely shot. Battery replacement may be your only option.

I'm thinking, that You are right
I'll replace battery
Thank You

Almost sure your battery is dead, or in a weird case it may be disconnected
I got an used X Style that wasn't turning on at all and it did the same things you described, i popped out the back cover and saw that indeed the battery was disconnected, after putting the connector in place it booted up normally (btw, the battery didn't last too long, it couldn't last more than 20 min and would turn off, so yeah you should change it for better)
