Update; Rangercaptain and 440bro suggested the power switch or the usb port may be the problem.
I dismantled the phone and got my ohm-meter, the power button's circuit is opening and closing as it should between pressed and depressed.
Furthermore I tested the usb port for conductivity at each pin, from the side of the usb cable that would normally connect to the pc all the way through the 'charging flex ribbon' to the phones PCB. all connections are good.
Editing this post as I try new things i find or the things i try that people suggest.
Currently my Note will not boot into recovery or it's ROM, I was running a version of Slimbean.
I can get it to go into download mode via the volume down + power key but I can not for life of me get any pc to recognize it via usb.
I have tried Odin, Adb, and Heimdall with five or six different versions of Samsung USB drivers, Version #'s 1.5.14.0, 1.4.6.0, as well as the drivers listed in the Note 'Super thread' ATT I717 v1_3_2200_0 and two other sets of drivers that did not have version numbers listed, but came from other XDA USB problem posts. I have also tried the Google drivers from the Android SDK.
I have done all this on two different pc's and different usb cables. I've read other problem threads about this and tried most of those suggestions I.E. Uninstall old drivers, reboot, install new ones, reboot, turn off internet, plug in phone. Nada, no sign of the device being recognized at all.
I've tried the 'adb devices' command while the device was in download mode, the command returns nothing.
the USB port still works so far as i can tell, if you plug it in to a charger or the pc the phone will try to boot like it usually does if it's powered off and you plug it in and the phone had been charging fine before this issue, so i've no reason to suspect a bad port.
I have however encountered this USB problem before even while the note was stock and functioning with it not being recognizable over USB, I eventually gave up and it's what caused me to install a ROM on it in the first place because i couldn't get the official android updates with Kies (they require a usb connection).
Would a USB jig be of any benefit in this situation? After searching through XDA forums and the like that's the only thing that seems like it may work but i haven't tried. I'm unclear if it will be of any benefit because the device can already access the ODIN downloading screen.
All in all I've been working on this for about 12 hours so far, so it's possible i may have forgotten something I've tried but i'll update if i remember anything significant.
Finally I'm aware there are two similar threads currently running on the XDA note troubleshooting forums,"Is my note bricked?" and "can't enter download mode" I am also watching them and trying anything that looks relevant but elected to make a new post as my problem is slightly different in that I can access the download screen. If you posted anything there that you think may have applied here, you don't have to re-post. I'll have tried it.
Your power button is stuck.

Thanks, I should clarify that the reboot cycle is not indefinite though. it'll give the boot vibration 6-8 times with a few seconds in between each vibration and then stop trying to boot. It also doesn't cycle every time, just occasionally. The other times it will give the vibration only once and then do nothing till you hold the power button down again as if you were trying to turn it on.
It will also stay in the downloading mode until i manually hold the power button down, so the power button is functioning correctly.

If you say so.
Take out the sim and sd card.
I have tried removing the SD card and SIM card as well. Makes no noticeable difference.
I can also add that the USB port still works so far as i can tell, if you plug it in to a charger or the pc the phone will try to boot like it usually does if it's powered off and you plug it in.
I can dismantle the phone and check the power button if you're fairly convinced that's what it is but it really responds exactly like you would expect. The press and return feels fine and the way the device responds to it also feels fine.
Yeah I'm pretty sure it's a stuck power button. If the phone is off and you plug in usb, or charger it should NOT startup by itself. If it does it's most definitely a stuck power button. So I'm guessing your phone is no longer covered by warranty?
Before you go tearing apart the phone try this first. Take off the battery cover and where the power button is you'll see a lil outline. Flick this area with your finger a few times. Flick it hard enough to mildly hurt your finger but not the phone. I had to do this for a while till I got a new note. If that doesn't help take it apart at your own risk.

It has always started up on its own when you plug it in, at least if it's out of charge. Of that I'm certain. I've had the phone a year and a half or so now. It may not boot up on it's own if you just manually shut it off and plug in a charger though. I don't recall ever trying that scenario directly. It could also be a functionality Slimbean added if stock phones don't do it.
I did just try your flick trick though, thanks. No change.
Just as another example on the power button, I can take the battery out and put it back in and the phone will do nothing until i hold the power button down a few seconds, only then does it do the the "i'm trying to boot" vibration.
Damn I was really hoping the flick trick worked for you like it did me. If you decide to take the back of the phone off, try flicking again anyways before you completely disassemble it. Once you disassemble it, there really isn't much you can do power button wise other than replace it. I'll attach a pic of the power button area for ya. I have one already torn down.
If it's not your power button, I wonder if it's your usb charger port on the phone.... That's an easier part to replace if it is.
I do feel like the USB port is a possibility, even despite my saying it appears to work. is it possible for the port to be damaged in such a way that it still allows the phone to be charged but not establish a data connection? When the phone went brick yesterday It had pretty much just finished fully charging. I had disconnected it from the charger used it a little bit, set it down when it still at about 98% battery life. Around 10 minutes later I got a text message, it made the god awful slimbean text tone (i hate that tone) I went to check it, turned on the display it then repeated the incoming text message tone about five more times in quick succession, locked up, and then died never to return.
I have had the phone apart before because i'm a curious cat, and didn't really mind voiding a warranty.
The only things that would make me skeptical of it being a usb port problem is. 1: It was charging fine and 2: the symptoms at least of the reboot problem itself are leaning towards a software issue the Slimbean install has never really worked great, and would crash and reboot probably twice a day.
Just because the button works doesn't mean it isn't stuck. I've only saved about ten phones by helping the owner to understand the cause of the reboots.
The fact that you already opened the phone increases the chance its the button. Because you said it rebooted on stock or custom ROMs eliminated software. Because your phone charges normally and is recognized by a pc shows its not the usb port.
But hey, what do I know. . .

He has more than one problem. He can NOT get a pc to recognize it. I missed it first too and had to re-read it a few times. So it could be the port, or the power button.
I think your options are....
-Find a repair center nearby
-Send it in for repair
-Find out which part is cheaper and replace that yourself first.
Sounds good. The usb port is cheap and easy and while the bezel is off you can verify the power button isn't stuck in its hole in the bezel.
Because he flashed a custom ROM from a stock ROM I took that to mean he had to connect to a pc through the usb port, either to Odin flash a recovery or Odin flash Slimbean. And he can still charge it. And data cables go bad, removing drivers doesn't take them out of memory, etc. So usb port isn't 100% bad for sure, but you're right, its a cheap, easy repair.

If the button is 'stuck' it implies that the it's either stuck engaged or disengaged correct?
If that were true and lets say it were stuck engaged, the power button should be acting as if it is pressed. Which at first would make sense when i say it reboot cycles. It however does not make sense that i can get into download mode and the phone never shuts off until I hit the power button.
It also does not make sense that if i pull the battery out and put it back in the phone does nothing. until i hit the power button. If it were stuck engaged the phone would immediately try to boot when i put the battery back in.
The rom has also been on it for awhile now, 6 months? So i don't exactly remember the processes i went through but i know i never got kies or odin to recognize it. And Yeah, pc wont recognize it now even tryin two different pcs, one of which has never had a samsung device connected to it.
That said I wont rule the power button out either, Is there a good way to check the power button with a multimeter?
I should also say I have the phone apart now so i could at least do external checks of the power button since you both thought it was a possibility, externally it looks fine the actual button inside the case (the little white button the big silver one hits) acts fine but the circuit inside could still be screwed i suppose, which is why i ask about a meter test.
Ultimately I think you're both right though, I'm just going to have order a replacement button and port. Start with the port since it's easier, and if that doesn't enable me to connect it to the pc to flash it try the button too.
Since you mention the ROM, it is possible to have a bad download, flash the ROM, and get into a bootloop. The usual cure for that is a re-download of the ROM, wipe caches, wipe system, and flash fresh ROM.
The sticking power button is a common fault of Samsung phones. Its not broken, but it just gets a little out of alignment in its hole in the bezel. If you already wiggled and snapped, you would have noticed a difference in the phone's behavior, unless there's lint under it.
I think you have your plan -- replace the usb port, and check the button while the phone is without the bezel.
The usb port is on ebay and there is a Youtube video for the process. Everything is here:

Good luck.
Thanks for the Help Ranger and 440.

I'm going to try the phone tonight on a friends PC. Who doesn't have another note but at least has a Samsung Gs2 and 3 that connect to Kies and see if i can get it to establish a connection.
If anybody else has any ideas on troubleshooting the connection between the device and a PC i'm all ears.
Good luck!

Well interestingly, when i hooked it up to the friends pc (using one of the same usb cables i already had) not only did his pc recognize it, the phone also booted up immediately. with 15% battery life remaining.
Strange strange.
Hi,
Last week, I spilled a bit of beer on my Huawei Ascend G700. The phone started to turn the volume down at random moments when there were no buttons touched. I figured it was best to turn it off, pull out the battery, and let the phone dry.
It's been a few days now, but when I try to start the phone now, the only thing that happens is that only "=> FASTBOOT mode..." is showed in the bottom left corner. Nothing else, and it stays there until I pull the battery out.
I have tried disassembling the phone and clean it as far as I could, but it made no difference.
If I push the volume up button together with the power button it starts the recovery mode, but I can't do anything from there. And I can't connect to phone to my computer. (It isn't recognized).
I have found similar problems online, but with the difference that I have not rooted this phone. Is there a way to get the phone back working? I would like to keep the original firmware, if possible. For I can't think of a reason why it would be helpful to still try to root the phone.
So, the only thing that happened before my phone freaked out is that I have spilled a bit of beer on it (only a few drops, phone was in a case). Never rooted the phone. Phone was only a month old. I think it is running on android 4.2, but I'm not sure.
I think the volume down button is still making contact somehow as the beer has not dried off. Or maybe the button is being pressed somehow. I say this because when You power on an Android phone with power down key, it usually boots into fast boot. Try cleaning again.

I tried. I disconnected the connection cable from the volume button, but it doesn't make any difference.
I don't think this is the right forum, but I couldn't find one specifically for this device.
I'll start with a brief explanation...
I work in a motel where things are constantly being left behind by guests. Policy requires that we hold lost items for 30 days. At which time employees can take said items. I always get the phones/gadgets.
So, I just got one of these LG Optimus Dynamic devices. However, it won't turn on (probably the reason they left it behind). When I press the power button, I just get a solid white screen... Is there any way to fix this device, or is it just a paperweight at this point?

@Can0dope
Remove battery. Wait 10 seconds. Put battery back in. Hold Volume Down and plug an Usb cable in it (USB must be in PC with an os running also). Tell me what happens.
@christi9503 I followed your instructions. It booted up to the white screen again, the screen flashed, it made a boot sound, and vibrated. A crack has recently appeared under the screen. Touch is still responsive.

That is strange that should get you in the emergency mode. Try again holding button up. If this does not work power it off hold Volume down+Home button+Power. wait 8 seconds release power. tell me what happens.
Hi I'm really hoping someone can help me. I received a Sony z2 tablet spg521. I was told it was new but it would not power on or charge, and the charge light would sometimes blink red. Well I got the fixed or so I thought by doing a soft reset and then pc companion...sounded simple but spent a couple days trying to be successful. Sometimes my computer would recognize it sometimes it wouldn't.... Any way I finally got it out the blue dont know what the difference was I was just happy it finally worked... I then fully charged...yadayada and used it flawlessly for about a week... It would turn on and off, battery held charge like its supposed to, everything seemed to work.....then I went to power off but hit the restart by mistake....no there is no power again and this time it will not do a soft reboot.....no light ever....computer will not recognize ever....I have been trying off and on for a few days.....among-est my research to try to correct it seems like this is very common....when i shut it off the battery was over 50%..so how can something work fine then just die like this??? Ive seen that sometimes with sony if you disconnect the battery and the reconnect this will work... does anyone know? does anyone have any advice before I take apart this cherry tablet to try the battery thing???
I would really appreciate any insight as I have fixed many of my own problems and for others from advice on this site. Have a wonderful day and thank you!!! :silly:
ok today i tried to use flash-tool that Ive read about on this site....when it asked to plug n device computer recognized it and red light came on, but flash-tool did not recognize it....torn between letting it set and seeing what happens or trying to get the flash-tool to work, I chose the flash-tool...bad mistake when I went to try to reconnect and see if the FT would see it..it was no longer recognized by the computer and no light but computer did say USB device not recognized and not installed correctly.....now I already have the right drives so now Im really confused..tried a couple more times with same results and then once again nothing...no light no soft reset no recognized at all by computer not even not recognize USB....so disappointing loved the tab but this is insane that sony does this as its not user error but sony error and they dont even man-up and try to make it like you dumb or something....will try again..when i calm...
reset the device by pressing power+volume(up or down) for several seconds. It seems like a toasted one, possibly caused by putting magnetic charger on wrong polarity.
Thank you yes Ive tried all kinds of resets I have found...I agree seems fried but I would not know how. I have not used a magnetic charger...only the regular sony one that came with it....
So last few days I have tried off and on again....now computer recognizes by making noise when connected and disconnected but does not show up...PCC does not recognize it.....flashtool says its connected in log but when it asks for it to be plugged in it never leaves the screen telling you how to connect....when I try to connect the charge light comes on for about 4-5 secs then turns off....still no vibrate when try to reset still no light when plugged to a charger.....I want to get another one but I am scared this will happen again....gonna chuck this one as if time is money then I have well exceed the worth in time... I only got this because some time ago a sony z1 came my way and I so love it...i recently upgraded to z3.....i have a lg pad but screen got broke so I got the sony tab....maybe Ill just fix the lg

Mine is kinda toasted and this is how it works. Whenever I have a problem, I have to reset by pressing power + volume up, as soon as I hear three vibrations, I turn it on by pressing power button. Otherwise this tablet will just repeat sony logo and no boot. If you have bought one "NEW" make sure to return or replace it. If you want to enter fastboot mode, repeat the resetting routine and pressing power button to turn on, but also right after that or even simultaneously press volume up to enter fastboot mode with usb cable inserted, or volume down to enter flash mode. either way, your unit is toasted and sony sucks.
Well, I have the same problem, and isn't fun. Just very extreme rare cases it turns on the screen charging the battery, but doesn't turn on sadly
I did a happy boot today after 3-4 months off with several times trying turn it on, and did all the tricks from all treats about SOD
Last weekend I did a full charge from deep red to green light and battery animation on screen at start, but no luck.
I put it back in the box
This weekend I got some visitors, one of them asked about the tab, told him it didn't work and showed to him
Pressed the power button and to my WERY BIG surprise, it vibrate and turned on as nothing was wrong
The battery was only 54% after one week off. it received a update (264) and I installed as normal, turned off and on again as normal and happy I was

I believe my phone is broken and I need to return for warranty repair. But wanted to describe it here and see if there are any suggestions and advice.
I was charging on an airplane and I tried "chopping" moto-action to turn on the flashlight and it didn't work. I thought that was strange so I disconnected my phone from the power and reset it.
It did not go past the boot screen. I tried holding down power + volume down and it enters the other screen, and I tried scrolling down to enter recovery mode, but when I hit the power button on that selection it goes to the boot screen and stays there again.
If I try to plug it in, it no longer even responds to pressing and holding the power button + volume down anymore, I have to unplug it for it to respond.
I have tried charging it from the wall, and I only use the motorola provided cord and block.
The phone, even after being plugged in and charging (the motorola symbol on the back lights up when plugged in to indicate it's charging), does not actually charge.
When I enter to the other screen it now shows 0% battery warning.
What can I do? I live in the US but this phone was purchased in the UK, so US motorola support will not help me. I'm worried I will have to mail my phone to the UK for repairs, and their live-chat is not active during the same waking hours as the US so I am using my backup phone, but this really sucks...

I guess the only thing you can try is to flash stock firmware on your device search the firmware on google according to your baseband and use adb method to flash it...
