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)
And then the "menu" soft key blinks a couple of times and then back to nothing

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)

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 have tried the following:
- Leaving the battery out for different lengths of time from 5 minutes to an hour
- Taking the battery out, plugging in to USB, putting the battery in, turning the phone on
The phone is rooted, unlocked and uses a custom ROM. I dropped it LITERALLY a foot and a half from a table onto a soft carpet, and didn't notice until a long time later that it wouldn't turn on. I don't know if the two were related as I didn't look at the phone after I dropped it.
I can only power the phone on if I use the method of taking the battery out, plugging in to the USB and putting the battery in, but whether I try the power button or any combination of volume up/down and power button, the phone stays on for a couple seconds then the screen turns off.
A few times the Google logo has come up and then disappeared and I've had some white scrambled/garbled display toward the bottom of the screen. As it sits plugged in to the PC now with the battery in, every so often it does the garbled lines on the bottom of the screen.
edit: Trying the Volume Down + Power for recovery flashes the screen with "Start" and the Android bot on it for a second, but then it turns right off again.
I'm thinking it's probably pretty screwed up but if anyone has some suggestions, I'm all ears. I'm worried about having to bring it in for repair (even though it's under warranty) because it's rooted/unlocked/custom ROM'd.
Any help is greatly appreciated.
After reading all this, my guess is your device is physically broken. Sorry man.
Sorry if this question's been answered in another thread, I tried searching and couldn't find any question that exactly matched mine, or any response that solved the issue.
I purchased a used, unlocked Galaxy Nexus from ebay around a month or two ago, in near perfect condition -- this has been the first time I've had any problems with it. It's probably not applicable, but after the release of the dev preview for Ubuntu phone OS I rooted the phone and reinstalled the factory image "takju 4.2.2 (JDQ39)".
Anyway, a few hours ago I accidentally bumped my phone off of a counter in the kitchen onto the tile floor. I picked it up and looked it over, and noticed no visible damage whatsoever, although the plastic cover had been partially dislodged; however, the phone's screen was dark, and the phone was unresponsive. I took out the battery and replaced it, then held down the power button. The phone vibrated once, like it normally did when booting up, but the screen remained black and the phone unresponsive unless I removed and reinserted the cover again.
I've tried charging it, plugging it into my pc, removing both the battery pack and the SD card, taking the battery out and rebooting it while holding both power buttons down, but I still get no response (and my computer doesn't recognize the phone when I plug it in). After reading a post where someone had success reconnecting the display, I unscrewed and removed the casing, then disconnected and reconnected the display from the motherboard -- still nothing.
Is there anything else I can do, or is my phone beyond repair?
Did you check the other connections while you had the phone apart?

I opened it up again and took pictures, but I'm not very knowledgeable about this sort of thing, so I can't tell if anything's wrong or not. Should I remove the motherboard to get a better look at the display?
You're talking about the back cover which became dislodged upon impact? I'd say you're lucky that the phone still gives that vibrate. But it seems there are so many things that could go wrong from an impact. Do you have fastboot? [I know you said you tried holding down both volume buttons and power, but try pressing them first then tapping power.] If you don't have fastboot, then your only options would be omapflash and odin. If these do not work, it's gonna be hardware. Maybe the display is gone, if you get the vibrate but see nothing..
I dropped my HOX and I got another HOX with working mainboard. I replaced it and everything worked except for very faint backlight and flickering. So I disassembled the phone and put it back together again. Now I can't start the phone anymore and the solid red led burns when connected to the charger....after I connect it it flickers one time, very fast. Does anyone have an idea what it could be? So pissed of right now...
Hi, if you don't have any power at all eg no vibration or lights on three bottons at the bottom, it could be that the power connecter is not properly plugged in. follow cabble down from power button, plug is hard to get at unless you unstick power button from cassie.
If you have some power check lcd is working by using a bright light near the screen and closely checking to see if you can see anything, could be backlight not working.
just my 2cents
feel bad for ya!

The cable is connected and I'm afraid the display shows nothing Thanks for your reply.
This might work

Okay, I have experienced the same thing and I'll tell you what I did to fix it. I dropped my HOX after owning for only a few days and the screen was cracked. I ordered a replacement LCD/ screen digitizer part and took it apart. One of the things that I found was that there was adhesive everywhere, including adhesive on the connection to the battery.
After it was taken apart, I attempted to test the new screen. It was then the LED turned solid red and the phone would not power on (even after 10 minutes of charging). What I did was remove the adhesive from he battery connector and disconnected the battery completely. I plugged it back in 10 seconds later and it turned back to flashing green (which is normal because I had several missed texts).
So my solution was just to unplug the battery and it worked just fine. The hardest part about this whole process was putting the cover back on, especially on the side with volume buttons! Hope that helps.
I have exactly the same problem. The difference is that now that I took it off charge, the red light is flickering on and off. I cannot get the display to show! Please please help.
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!
Chris
Okay, read some more on here and got it into boot load mode. Pressing the up arrow puts the start arrow at the top of the screen pointing to the power button, the down arrow "restart bootloader", however, pressing the power button does nothing.

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.
