My fascinate will not turn on unless its plugged in. Once it turns on it runs fine. If you hold the power button to turn it on it will show the battery icon, but will not turn on. If you plug it in it will turn on and work fine. It also thinks its in usb debugging all the time. not plugged into anything and it thinks its debugging.
Very strange.
Are you on Froyo? Using a rom? You might have the screen of death. If you have clockwork recovery you can turn it on that way.

My son's had the same thing, left the battery out for a day with the intention of returning it under warranty, put the battery back in and it fired right up without an issue, and havent had one yet.
Another question, are you using the stock battery or an after market job?
Without one of the tweaked kernels, the after market batteries wont work at all...
I forgot about this thread. My problem is when the phone is turned off, it will not turn on unless its plugged in. you push the power button and you see a picture of an empty battery. You plug it in and wait for the battery to turn green, and the phone will fire right up. Tried a new battery, and nothing. I am going to call vzw and see what they say.
Any resolution on this? I am having the exact same issue with my Infuse (AT&T).

NP I had to do it all the time on my wifes alias.
Did you try a different battery?
At this point I would go stock and see if a verizon store will try another battery for you.
Good luck!

exact same problem as quoted above.
Some times the USB port gets gunk in it, try taking a piece of paper fold it a few times make sure the width is like half the size of the usb micro jack and slide it in to the usb port. fold it so it is snug but not tight move back and forth, do both top and bottom of the port but be careful on the thin side. basically your cleaning the contacts to remove and film.
Good Luck
If that still doesn't do the job chances are it's a hardware issue.

This is a very accurate description of the issue. I too am having the problem however it is on AT&T captivate. In my case, it only occurs when I am using a MIUI ROM. I have flashed multiple ROMS, both prior to and after discovering the problem and only have this issue when using MIUI ROM (Which is awesome in every other way). Two other things I would note. I have purchased another battery and it behaves identically, and MIUI drains batteries like a mother. Even swapping out a completely charged battery does not resolve the issue. Maybe someone brighter can explain how the phone "reads" the battery charge level while off.
does anyone have this problem with 'stock' phone?
I'm having the exact same issue with my Continuum. Thought maybe the USB port had issues, but it charges a battery just fine. It just won't acknowledge it's charged and turn on unless it's connected to a power source. Without a cable plugged in it just shows the big empty battery icon with a non-moving progress wheel on top of it for 3-4 seconds then screen goes black. With a cable plugged in it displays that, then changes to show the true charge of the battery at which time I can start up the phone. I restored my phone to factory defaults earlier today, but this problem persists.
Has anybody found any solution to this?

I have the same issue with my Samsung Epic. Anyone find a fix?
I also have this problem. I have discovered, however, that while I must plug the phone into a USB cable, that USB cable need not be plugged into a power source or anything at all. I can reliably (100% of the time) power up with a USB cable just laying in my drawer. I can also reliably (100% of the time) not power up without plugging into a USB cable.
In other news, I have also discovered that certain low-level actions tends to screw up lots of things. I can Odin just fine. I can flash ROMs, kernels, etc. just fine. However, I cannot restore a nandroid. Whenever I restore a nandroid, as best as I can tell, my partitioning gets all jacked up. When this happens, I can't do anything but boot into recovery (although once this happens, I can no longer flash ROMs) or Odin. Doing a full Odin flash restores functionality (in the sense that we all see where we need a USB cable to boot up), though. So ultimately, I think these phones have defective memory and that's what is ultimately causing this.
I bought this phone a couple days ago for $100 so I'm not out much (and can probably get most of that back even acknowledging the issues). Sure would have been nice for that person to have told me there were these issues. But oh well. C'est la vie!

Has anyone had this problem?
After three trouble free months, my phone has developed a a very strange problem.
After charging, it behaves as if I'm constantly connecting and disconnecting the phone to a PC. It bleeps whilst showing the battery being connected to a charger and then imidiatly acts like its been disconnected by bleeping and running media scanner on both SD cards. It also shows that its connected via Kies, even though all this is happening whilst only being connected to a charger!
I've already done a full reset, which helped for a few days before it came back. It normally sorts itself out after a few minutes but the period before it "calms down" is getting longer. This morning I removed the battery for an hour but it continued in its "loop". Another, possibly related symptom is that as soon as the battery is installed, the phone boots up without being switched on. The same thing happens if I shut the phone down, it just powers up again!
Any thoughts?
had you if ever dip the bottom part of your phone? sounds like short-circuit issue or I maybe wrong.. try bringing in on to the nearest service center for warranty
Sounds a plausible theory but as far as I can tell, it hasn't got wet. Its been doing it for a few day now, so I think if it was damp, it would have dried out by now.
Thanks anyway.
I got the same problem. Let me know if you figure it out.

my friend had a simmilar issue and it was damage to the usb port , it kept thinking it was connecting to the pc or charger , it also wouldnt charge when plugged into a wall point and went into usb mode and vice versa when he put it into a pc
he sent it back for repair and they sent him a new phone
it may not be what you have but it does sound simmilar
i would try a few things like a reset , format the mass memory , install firmware again , dont restore back ups but set phone up fresh like you would do if you just bought it , then see how it goes , it could just be a corrupted file or system error that could be fixed bya full wipe and fresh install or it could be like my friends and the usb could be on the way out
on the topic of usb ports i do think they could have been better designed and iam hoping mine doesnt break as its needed for hdmi out , charging , docks , etc etc
Thanks Buxz,
As a follow up, I put the battery back in after taking it our for about 3hrs and all seams fine. I know that it isn't a permanent fix but I think it points more to software than hardware, which in a way is more annoying as its all about trial and error, as you described. A mechanical fault is more straight forward.
I just dread having to charge it again!
Regards, Woolly.
UPDATE
Charged it overnight and no problems when disconnecting it this morning. So far!
If anything, the battery life it better than before the problems. The fact that removing the battery for 3hrs broke the cycle of connect/disconnect, makes me think its soft/firmware related.
Woolly.
So the past two nights iv let my rezound battery go dead. The problem is it wont charge a dead battery. It charges if there is some battery and its on but when it is dead it is dead. The fix was I had to put the rezound battery in my tbolt to get a little bit of juice.
Any ideas or similar problems? I am unlocked with the htc unlock tool and running nils business sense?
Could it be a rom bug?
Don't let your battery die. It's bad for it anyway.
Sent from the Rez Beast
Once the battery is dead what does the LED on the phone do? If it blinks for a while it is either too hot or too dead to turn on, but it can still charge eventually. If the LED is not coming on at all I would pull the battery out and connect the charger with no battery and see if the LED comes on. If still no luck, get a new charger.
Blinks then Charges
I had the battery die on me once (on a prior battery and prior rezound). The phone will blink orange for a WHILE (I tried 3 different chargers not knowing what it was), but eventually started to charging. I think patience is needed. If, after 15 minutes, you still aren't charging, then that's something (but longer if the phone was also hot).
If I hit he power button with or without the battery in the led will light for a short time. I had it plugged in all night and no charge. I used two different plugs.
As for not letting it die. I know its not ideal but I couldn't help it.

+1. Same thing here.
KORM via the beast known as the Rezound.
I let my phone die completely once. I freaked out that my phone wasn't charging. I went onto HTC's site and it said that it could take 20 or more for the led to turn on while charging if the phone was completely dead. Just plug it in and be patient. It will charge and the led will eventually turn on.

I had this problem too, and am a little concerned I have a defective phone
So I had this issue happen this weekend. My daughter was using the phone when it died. Couldn't get it restarted. (I am unlocked via HTC, stock ROM with bloat removed. Phone is a week old.)
After messing with it using the factory charger/cable and other chargers/cable combinations I got nothing. Light would only intermittently come on for a second or two then go back off.
I charged it over night with the factory charger/cable. Didn't work the next day. Charged it all day and night with my old charger/cable that I know works. Didn't work.
Tried multiple variations of taking out the Battery/Sim/SD card and using the plug-in chargers & CPU USB variations with no success.
Luckily, I had ordered a new spare battery and it came in the mail before I returned the phone. Plugged it and it started up fine.
But my concern is that my phone is not properly charging. I have also had other similar charging/battery life issues that raise concern.
As far as not letting it die, **** happens and phones die, if this is a reoccurring problem, that in my mind is pretty unacceptable. A phone should charge when its plugged in no matter what. I may end up returning it to see If just got a defective phone/battery.
My phone will turn on then off and im starting to think it has something to do with the battery. But when it started it was in tue yelllow on the status bar, now i have it charging without being turned on and the indicator light is on but hopping mine will fire up soon. This all just happened to me within the last two hours lol, already called verizon to get a replacement but still going down there tomorrow.

--I agree, but once it gets down to 5%, why not just turn it off knowing the problems people are having so wide spread now.
Under the exact same conditions I have had the same problem with a warm battery reboot. It seems to occur when you are talking on the phone and let it die. Once it dies the phone will not reboot. My wife has the exact same phone. When I put her battery in my phone the phone works fine. My wife’s phone dies every night and she simply plugs it in the wall and it charges no problem. Again the conditions seem to be related to the battery dying while it is hot. If the battery dies while the phone is cool and not used then it seems to reboot no problem. I will go to Verizon tomorrow to look for a fix. I will let you know what happens.
I'm also having this problem but i can return my phone because i unlock it or can i return it ?
Check and see if your battery is 3.7 or 3.8v . I wonder if it is related to the charging issue with the 3.8v battery some people seem to be having.

I had the same issue with my OG Droid. Would kill the battery and it would stay dead, even after a whole night of charging. The above method seemed to work for me.
I make 100% sure mine never goes totally dead after an experience I had with my Droid Charge.
I accidentally let it die completely (I fell asleep when it was almost dead & it ran all night). The next morning it was off, I put in a fully charged battery & it fired right up but started FCing like crazy. Every single thing I clicked on force closed immediately, I had never seen anything like it.
I was running a custom ROM & kernel & had done a nandroid BU the day before. I restored the BU & the phone ran perfectly again, but that scared me enough that I made darn sure it never happened again LOL........

Holy ****!!! I think I may have found the fix! I have had the same exact problem as everyone in here. It seems to happen once I root. My Rezound would die completely, then after plugging it in, the light would come on for 5 seconds or less then shut off. I plugged it into my computer and Windows makes the USB Connected sound, so I figured something is happening.
I went into my command prompt and *adb devices*. It showed my device, but says in recovery mode. I then *adb reboot bootloader* and the bastard rebooted into bootloader! From there, I chose "REBOOT" and it fired right back up! Anyone who is having this problem, please try this and let me know if it works for you!
***UPDATE***
It appears when the battery dies all the way and then doesn't charge, the phone is automatically going into recovery mode even though nothing shows on the screen. I had my SIM card out when I tried this the first time, then when putting my SIM back in, it started doing the same thing. But again, it was going directly into recovery mode. This time, I tried a simple *adb reboot* and BAM! I'm back up and running! Again, let me know if this works for you, or if you need help doing this, let me know.

Yes... HTC phones never charge "powered off" When you turn it off and then put it on the charger, it is actually entering/booting a special screen off recovery mode during charging.
CWM recovery on the rezound has trouble charging a completely dead battery.
Use Amon RA recovery.
Hi.
I've got a Galaxy S2 (international version, unlocked). Its worked fine until now.
Ive had it lying around for a bit after getting the S3 and thought about selling it. So i checked it out again. Battery empty so i started charging It - charding battery screen was displayed - so fine.
Then I noticed some dust in the speaker grill and I wanted to clean that out. I used my breath and a needle to get it out.
Afterwards it did not power on anymore, the screen remains black and no sound. But I did not even poke around that hard?! Can it be damaged just from that bit of cleaning?
I tried letting it lying around for a while, then pressing the power button without battery to drain all remaining electricity and finally tried both soft reset (power button for about 10 seconds) and hard reset (power button and middle button for about 10 seconds).
It did not turn on.
Then I tried turning on with my usb jig. No luck.
I tried charging the battery again (since it was about empty). No change.
Since the phone has 2 year warranty I think I considered sending it for repair. But I remembered that I had rooted it. They will not repair if its rooted I hear.
Is there any other thing I can try?
I assume this is a hardware error and a physical repair is necessary (PCB replacement?)?
Or would a JTAG suffice?
I'd even consider doing a repair myself (getting replacement part and doing a peplacement myself) if I knew whats was wrong...
Please give advice!
can you boot into download mode ?
try to get another battery. it might be just a dead battery.
I cannot boot into download mode.
While it may be a dead battery I would assume connecting it to charge via USB (and I did check that the cable is ok and does charge by checking with my galaxy s3) would allow turning it on as it originally did (got into the charging mode where it displays the battery level). It does not do that anymore.
have you tried using another battery?

I asked a collegue at work to charge my battery who also had an s2. So the battery definitely works on a properly working s2.
I used that battery on my s2 and it still will not boot up or show any signs of operation.
Is there a way to find out what component is damaged?
I'd like to try and replace it, but that only makes sense if I know what component is the problem.
If you're not experienced at testing/working with microelectronics, you have no chance of fixing it yourself. You're more likely to completely trash the phone if you try. That you asked a question like that suggests you don't have the knowledge/experience required.
Do the smart thing & either see if it can be JTAG'd by a 3rd party repairer, or take your chances with Samsung/authorised repairer & hope they don't notice/don't care/can't tell it's been messed with.
The other issue is, how could anyone here possibly know what's wrong with the phone specifically ? We're not there with you looking over your shoulder as you take the phone apart & we certainly don't have x-ray vision to be able to see inside the phone over distance.
Walking out of work yesterday, I swapped my dying battery for my freshly charged one, and powered up the phone. I see the Samsung logo pop up, and then the CyanogenMod wheel start spinning, so I slip it in my pocket. I pull it out a couple of minutes later to check something, and the screen is black. I press the power button a few more times, and the Samsung logo shows up again. Apparently my phone was off. So I wait on it to boot up, but it never leaves the Samsung logo. It sits, and sits, and sits...for a good 30-45 seconds, it sits on that screen. And then it goes black. I try again, but nothing happens. I switch back to the dying-but-not-dead battery, still nothing. I leave it to sit on the seat of the car with no battery for the drive home, and try again. Nothing. I leave it to sit on the charger for a couple of hours, both with and without a battery. Nothing. I leave it "charging" overnight. It's warm in the morning, but still nothing. I can pull the battery and put it back in, hit the button, and a little while later it will heat up, as if it's running and something's hitting the CPU...but no vibrations from the phone, no sounds, no anything at all, other than the heat. I tried my jig just now, as it was in my desk at work. More nothing. The phone is cold, the battery is cold, it might as well be a rock.
So...any chance of saving this thing? I'm really hoping to hold out for Black Friday sales to replace it with an S4 or something. If I can get this thing to last me another two months, I'll be happy. If it goes belly up November 30, that's fine. I just hope I can make it last until then. I already had to throw down $50 to get my wife a limp-along phone off Craigslist...am I going to be stuck doing the same for me?
First see if you can boot into recovery and perform a wipe data/factory reset. If not, see if you can get into download mode. If you can, flash back to stock and see if that lets it boot. In any event, you should perform a wipe data/factory reset at the earliest possible moment, even if you have to reflash the firmware first. If you can get back to stock, you should be able to reinstall your custom firmware.
So far I can't convince it to acknowledge that it's even on. The only sign it's not 100% dead is that it warms up when plugged in. I have no idea if it's actually doing anything other than sending juice to the battery because there's nothing on the screen and no vibrations or sound to alert me that it's doing anything at all.
:-/
I'll add that my computer doesn't acknowledge the phone's existence. Linux desktop, lsusb shows nothing remotely Android/Samsung related. Granted, a failing microUSB port on the phone isn't helping, so I don't know how valid this particular test is.
So u are in the need to enter the fast boot mode or else try the official firmware installation by the help of SD card.....
Hit thanks if this helped you...

...could you explain either of those? Fastboot, from what I can tell, is an HTC thing, and has nothing to do with Samsung phones in general nor the i777 in particular. As for firmware installation, is there a way to do this without any screen, PC connection, or feedback from the phone whatsoever?

Some Samsung phones have fast boot. I think the S4 does. The I777 does not.
If you can get the phone into download mode, (and if your usb connection is working, which I think from what you said may be in question,) then you can use the Samsung tool, Odin3, to flash firmware. You would have to use a Windows computer since Odin does not work on Linux.
I think your main problem is that you have a failing USB port. You should consider buying a replacement and putting it in yourself. It is supposed to be fairly easy. Once you have that working, you should be able to recover your phone.
Could it be possible that whatever it was trying to run drained the battery and now it's just refusing to charge? I had almost an exact same situation happen to me. I ended up having to buy a cheapo external battery charger from amazon to charge the battery and finally get it to boot.

Sadly, download mode doesn't seem likely. The phone is basically functionally a rock, with the limitation that it's probably easier to break than a rock. I may venture down the replacement USB road, although I'm a bit leery of spending money on the device, given that it won't even power on.

That's what I initially suspected, but I actually have a Samsung charger I bought off Amazon that came with a spare battery, and I've charged both batteries with it to full capacity. What does appear to be happening is that when it's generating heat, it's actually discharging the battery rather than charging, as a battery pulled from the phone takes much longer to charge on the external charger than one that has been charged from the charger, pulled, let sit, and put back in the charger. It's possible the phone refuses to power on until it can charge, though, because I too have had that issue in the past, and the only solution was to let it sit on the charger for a few hours. The first half-hour or so, nothing happened, but then eventually I'd get the battery charge animation. Sadly, letting the phone sit overnight did nothing this time around.
