so i think my power button broke? i can navigate once it is booted, but idk how to boot, i at least want to have some functionality before i take it in in a few days.
i can reach charge screen by plugging it in, sadly when it occurred i didn't realize the button wasn't functioning and thought it just froze so i pulled the battery out, now i can't boot. :X
EDIT: its busted for sure, the button is loose, and pops out a bit on one side.
Close this ****, ADB is my best friend and its nice always having debugging on.
really simple actually, get adb, run "adb reboot".
Done.
phone has to be in debugging before hand though.

If you don't want to carry a laptop or computer around try this
it takes some work but at the end it will be easier
1. get an old toy or anything you don't need that has 2 or 3 AA battery slots.
2. take it apart and take the part you put the batteries in with the wires there will probably be a red wire and a black wire or a red wire and a yellow wire.
3. take an old USB cable you don't need that fits your phone and tear it apart and keep the side that fits your phone
4. use electrical tape or a soldering iron and solder or tape the usb black wire to the toy's black wire and red usb wire to red toy wire.
5.plug in your phone and it will start up.
It does this because the 2 or 3 double A batteries provide as much power as pressing a power button for a few seconds to turn it on.

I need to turn my phone on without using the power button. The power button on the top left side of the phone is broken and no longer works. This corner of the motherboard is slightly exposed, and I have previously turned the phone on by touching the mobo with a paperclip, but as far as I'm concerned it's just luck. I was hoping for either turning it on by computer, or a map of a mobo that showed what I could push/touch to turn the phone, if possible. Or, any other method. Thanks.
EDIT: I don't have my USB cable, so now I can't use any computer method anymore..
EDIT2: I found the problem: The small chip/power button attached to the motherboard came off. I'm hoping I can find someone in (Raleigh, NC) to solder it back on for me, assuming that it can be soldered.
What I was doing before with the paperclip was magic.. I just touched the pins and it turned on, but I can't do that anymore
EDIT3: Shorted out the power switch pins. My new power button is my battery

Look like your back to the paperclip then. Sorry, i had too, but seriously, I don't think it would work with the computer anyway. There's no way to communicate if it isn't on. Can you see where the button connects?
The only way to correct this is to either fix the mother board or continue using the paperclip. Unfortunatly most electronic devices like this, only have one "actual" method for turning them on. I do like your idea of bypassing the switch to turn the unit on though.
Updated. The power switch came off the motherboard.

im no expert...but that sounds like a not-so-good thing.
I fixed the issue.. sort of. Shorted out the power switch pins on the motherboard, so it stays "on" indefinitely. My new power button is my battery
A limiting fix, I guess.. but it works.
wow..you are not gonna let this one die huh? maybe its time for some parts? or a new phone?
Why should I let it die? Everything on the phone is fine, I just lost the power switch. Now I got the thing hotwired and it works fine.
I'm locking this thread....no more need for it.
I searched as best I could so please bare with me..
Brand new e971, less than a week old and I managed to drop it in the toilet bending over to tuck in a shoelace after I took a leak. Fell out of my sweater pocket, and right in the bowl.. that'll teach me to put the seat down.
Anyway, I was out somewhere and obviously didnt have the sim key or any tools to crack the back and pop the battery..I 'windmilled' to get what I could out.. but that was the best I could do. I held the power button down hoping itd shut off and it eventually did, flashed something on the screen and that was it.
When I was able to I opened it up and popped the battery and dried whatever water was inside, whcih there was some.. took the mainboard out, blew it off with compressed air (it was actually dry, all the covers worked well). Put it back together sans battery and put it in rice for 36~ hours or so (would have waited longer, but I was confident I got the majority of the water out in the first place).
Phone won't power on though. The best I can do is get it to start download mode by pressed vol up+down and inserting the USB. Plugging in the USB on its own sees the charge indicator flash red intermittently, in a very long slow frequency - im thinking the battery is fried, maybe the power button too. The LG logo comes on the screen for a second and disapears for about 5, and repeats this cycle.
I've never rooted or messed with anything like this before but someone said I may be able to reflash the phone and have it work.. but I really have no clue. Any advice would be appreciated.. like I said this is brand new :/

That reflashes new stuff.
If you hold down Volume Down + Power Key you should get into factory reset, can you see if that works or you might have fried the storage or something.
If you somehow get it to work but need battery you have here:

Which ships World wide I think and pretty decent price.
Hope it works and please come back and tell us how it went.

Thanks for the response
vol down + power key has no response
Im tempted to think the power switch is broken and the battery shorted and is dead, but I am no expert
If I plug it into USB all it does is flash the LG logo, no lights nothing.
if I hold the vol down button down, when the LG logo flashes the back/home/search buttons illuminate for a second, and occasionally the red light will come on for a second, but thats it, other than being able to get into download mode the phone is a total brick. I'll check out your link when I get home. I have insurance but there is still a replacement fee and I can't afford it right now.. and the fact that I opened the phone I think they may try to **** me over with that even though its clearly water damage (indicators are all purple/pink)
thanks again

If the red light flash, it's usually because the power button is hold down. I think your power button might be stuck. Also try to plug it in wall and no on computer USB.

I was at work with the phone (dropped it out somewhere and took it apart and left there) so I had not tried plugging into a regular wall charger
Plugged it into a charger, backlight came on and the LG logo flashed, went away and flashed again, but a lot faster this time, and then I got a message "battery too low to power on!! I assume its charging, or trying to?!?! The red light goes bright, and then dims to nothing, and then goes bright again. Pressing the power button turns the screen on to the "too low to power on" screen again, and pressing again turns it off as per normal!
I'm kind of excited now, it may just be the battery after all.
Now, either the water shorted it and ruined it (and ill be checking the phone closely to see the lipo doesnt blow up on me..), or somehow the battery fully discharged? The battery was pretty full around the time of the toilet incident, but stranger things have happened right?

The indicator going from dim to bright during charging is pretty normal. It also means your battery is charging. Give it a full charge and see how it goes. And do try keeping your phone in your trouser pockets. It's safer that way.

I left it on the wall charger for a little over an hour but the phone appeared to make no progress so I unplugged it deeming the battery dead, that and I didnt want to run the risk of anything bad happening charging a dead battery (im a little leery with these lipo's due to my RC experience with them..). Maybe I'll try again for a while this evening.. but since the battery had a full charge prior to toileting, I can't imagine it totally discharging; is this possible? The other not so nice reality is that maybe the power circuit on the mainboard fried and its not reading the battery properly?
Yes.. will definitely have to keep phones in my trousers and put all seats down from now on..
So I'll try charging again for a longer time period to see what happens, otherwise I'll be ordering a battery on Monday and waiting about a week to two weeks for it
I'll keep the thread updated as much as I can without double posting
Thanks for the response
Well.. you'll never believe this but.. it works. Flawlessly as if the toilet never happened..
I tried the insurance route being that a battery shipped to me would cost half the price of a claimed replacement and it would have been a gamble.. so I went that route. Was told they denied my claim because my insurance was not activated because I need to make an outgoing phone call.. I only ever text and had not made one..
So down in the dumps and considering spending $25 shipping on a $30 battery, I went home and decided to try the phone one more time by reseating the battery..
I plugged it into the charger and got a blue battery charging.. I pressed the power on button and the phone came to life..
Not sure what the hell happened, maybe the battery needed to dry out inside or it wasnt seated just right the last time I tried but everything is working flawlessly.. wow. I am in shock.
Now I guess its time to root it
Thanks everyone for the advice and tips, but it seems all I needed was some time and luck!
So here's how it went:
I opened the phone, replaced the port (the small boardlike thing)
assembled my phone to try it.
The phone started
Then I put all the screws and sim card But I didnt get signal no matter how long I waited
So I dissassembled it again. I was a bit harsh and broke the "Power" button. (the rubber thing that makes it bounce fell off, and an small metallic circle that probably completes the circuit fell off as well.
(Google "galaxy note 2 charger port" for a picture, cant post external links @[email protected])
Checked everything was plugged properly and tried to start it with the tip of a paper clip to complete the circuit where the power button should be (that small round thing)
Nothing happened so I googled a method to start it without using the powerbutton:
youtube: Gre9qaJyCZw
Basically its to plug the charger, wait for the battery logo to show, unplug, take out the battery and put it back in quickly.
So I assembled the phone again to try that and when I connect it to charge it the screen flashes for half a second (no words no nothing, it just brightens up for a bit) And then the red led that means its charging turns on after a couple of seconds.
After doing the trick, the led turns on blue....then the phone vibrates a bit(seems its starting up, but with no sound or nothing in the screen)
And then the "menu" soft key blinks a couple of times and then back to nothing
So I just have no idea what to do @[email protected] I dont mind replacing the button but I would rather not spend on it if there's something else wrong with the phone...any ideas?
And I just bought this to replace another phone that broke ;_;
EDIT::::::
I replaced the charger port for the old one and tried the starting trick. but to the same result: after doing the trick, the led turns on blue....then the phone vibrates a bit(seems its starting up, but with no sound or nothing in the screen)

you probably messed up the mainboard or some connections.
Try to power it on with microusb board disconnected.
Make sure every single connection to the main board is connected properly

Any suggestion as to how I can start the phone with the power button broken and without the microusb board?
I already checked all the connections that you can see when replacing the microusb board (the back side of the motherboard) Is there connections worth checking in the front?
Do those symptoms sound familiar for any specific problems? (Like non working screen or motherboard)
- Charging takes a couple of seconds to turn on the red led when connected but shows nothing on the screen.
- Trying to start it with taking out the battery trick makes the led turn blue, then the phone vibrates a bit, then the menu soft key flashes a couple of times.
Update: I found 2 more symptoms
1° Kept restarting the phone with the battery trick, and a couple of times I could hear the music of the phone starting up, but it seems to be at random or due to some factor I have not spotted yet
2° If I connect it to the computer it detects the phone and lets me access the files. Kies detects it as well
If phone can be accessed through kies I think you have broken some connection between logic board.
Power button and volume + - buttons should have the same round metal part, which will work after swapping.
I think you should give up, maybe there is still hope for repair.

Thats the weird thing. if you take a look at that phone's board, the only things that are within "breakable" range when you open it with a plastic tool are:
power button
charger port
earphones port
volume buttons
And they all seem fine except for the power button. there's no other flexors or anything even remotely close to where the tool was used. (and where I got a bit rough)
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.

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.

I just drop my whole phone into water.
This is the first time so I a bit shocked and dont know what to do.
By the time I take my phone up, its about 10 seconds drowning in water.
The first thing I do is power it off.
Then I wipe the water away with a cloth.
Water is already inside and maybe short circuit happened? Causing the phone to boot itself and stuck in bootloop.
I cannot turn it off by pressing power button, so I connect my phone to computer and press power button and volume down button going to fastboot mode.
But the fastboot mode just lasts a while and then it goes back to bootloop.
So, I have no choice but to open up the phone for first time.
I found that a lot of water comes in through the charge port and there are many water on the board near charge port.
After drying it for few seconds, my phone exit bootloop and boot successfully.
Anyone know the actual reason the phone boot itself and stuck in bootloop?

Corrosion shorting out contacts, sending commands to the cpu.
Clean the board with isopropyl alcohol, the best concentration you can find, no less than 70%. The best method would be ultrasonic, but if you don't have such device, every switch and button should be submerged in alcohol and pressed/depressed a few time and then let it dry. The board should be cleaned with a q-tip. If you don't do that now, right after the water damage already started, corrosion will kill SMD chips in the future. At least now, you can save it long-term.

When you plug into USB the phone turns on. If the water shorts out some pins on the USB connector, it probably seems to the phone like it should turn on.
I have no idea why it bootlooped.
