I am having an odd issue and am seeking ideas on what to try next. Yesterday evening my GS6 in a tech21 case fell approximately 3ft from my basketball shorts pocket onto carpet. The phone was off at the time and had just been charging. Thinking nothing of the fall, I went to turn it on and it refuses to power on. I tried re-plugging it in assuming it might not have charged, and that doesn't seem to help either. I see no indication of charging (i.e. no screen indicators or LEDs) when plugged in. I plugged the phone into my laptop running Gentoo Linux and tailed messages but saw no indication of a device being connected which implies to me that it's not a broken LCD or a boot loop - the phone is literally just not turning on. Finally, I placed my phone on a OEM wireless charger at work and the charger pad LED indicates it's charging, but there's no indication on the phone screen or phone LEDs. To me this implies the battery has a charge, but something is preventing it from powering up.
I'm not sure how such a short fall in a case onto carpet would cause this. I have already tried doing a power + vol down and a power + home + vol up, neither seem to have any effect. I plan to take it apart tonight or tomorrow and am wondering if anyone has suggestions on which part(s) to focus on. I'm hoping (and I know it's a long shot) that just some internal cable got knocked out.

so I got a Samsung captivate from my friend. and was planning on rooting it and either using it as a game phone. or giving it to my friend.
background :
most likely has water damage. was out in a damp area.
finicky micro USB port.
issue :
will not boot with out USB cable plugged in.
boots just fine into 2.2, with cord plugged in, already got phone rooted and everything else works fine, just that odd boot issue.
Question :
Anyone know why this could be going on, I'm thinking water damage but I remain skeptical.
Just curious what exactly you mean by it won't boot ... Like you get no response at all, or it stays on the at&t screen, or what?
yeah, when the USB cord is unplugged and I hold down the power button, it stays at a black screen.
but when the USB cord is unplugged and I hold down power, volume up and down. it flashes a battery every 5 or so seconds with a loading icon in the middle. when I remove thumb from the power button it all goes black again.
I plugged my phone in last night and when I woke up today it was off. I pulled out the charging cord and held the power button with no effect. Thinking the cord may have slipped partly out and let the phone die, I plugged it back in and was greeted by the battery charging screen, showing full charge. I pressed the power button and the phone went black. On further investigation, it seems my press of the power button didn't have to do with it turning off, as whenever I plug it in it shows the full battery screen for a couple of seconds before turning off again. If I unplug it and plug it back in it just repeats this. I've reseated the battery, I've tried holding volume down and the power button, and nothing's changed the phone's behavior. The phone is completely stock, and never opened beyond the battery and card doors.
It's pretty old and I'm pretty sure I do have an upgrade available, so I'm not too upset if I have to buy a new phone, but I'd like to confirm that it is FUBAR before I go that far, and I'd like to be able to extract my data if possible. Any suggestions would be appreciated.

If you have access to another battery, you could try that, but since you're seeing the full battery symbol I'm guessing that that's not the issue. You can always recover your sdcard data by putting it in a card reader, but the phone's apps, app data, and settings may be more difficult.
Well, turns out the problem was much less serious than I thought: my charging cord has bitten the dust. I'm not sure why I've been seeing the full battery, but when I took it to the AT&T store, the person who helped me plugged it in and it started right up. I just need to get a cable that's not my years-old piece of crap that came with the phone.
I don't leave my tablet on the charger and I just went to use it and it wasn't turning on? I held the power button + vol button to soft reset, and nothing happened so I tried the reset button and it didn't do anything either.
Nothing's happened with it to make this happen that I know of.
Anyone hear of this?
Thanks
If I take the tablet off of the docking station and plug it straight into the tablet the amber charging light next to the power button blinks 3 times then stays solid.
What the hell?!
Whew! False alarm!
I just left it plugged in OFF of the docking station (I think it charges the docking station first thus not getting any power to the actual tablet for a little longer) and then tried turning it on and it vibrated and then powered up.
I almost pooped a bricked.
When connected to the dock, the dock will get filled first and then it will begin to charge the tablet. If both are running very low and you need to quick charge, charge the tablet directly first to give it enough juice to turn on.
Hi Guys,
I have a tablet that my boss gave me today to 'fix'. The problem that it is having is that it isn't turning on, nor does it appear to be even charging. He said he used it until it was dead, then plugged it in overnight to charge, but when he tried it this morning, it wouldn't turn back on. I've had it for about two hours now, plugged into an outlet (the plug is a bulky black 2pronged adapter with samsung written on the side and I have a usb 3.0 plug). I tested the charger out on my Galaxy S5 and it started charging without any problems, so that tells me that the charger is working.
After 2 hours of supposedly charging, when I press power nothing happens. When I press the home button, nothing happens. I read on here that some were having really slow charging times, but I figured after two hours, there should be at least enough power to show the little batter logo on the screen during charging. Now, though, since that indicator doesn't even show up, I'm starting to think maybe I should just take it back to VZW. I was looking at the back of the device to see if it had a removable back cover and maybe resetting the battery would fix it, but I didn't see an indention where you can pull the cover off at (like on the note or my s5).
Any suggestions?
2 hour are not so much, if you used not the original charger. Let it on the charger for around 12 hour and try again - disconnect charger, reconnect again if you can see something...
Plug it in, keep the power button pressed for at least 30 seconds. See if that starts it up.
Hi.
You might try getting an usb volt- & ampere-meter off ebay. They're about 10 bucks or so.
It'll tell you if the tablet is drawing power at all.

So i recently picked up an XT1254 for a great deal. The phone is pristine, not a scratch on it. It looks brand new. It is totally unresponsive. If I plug it in the light on my charger turns from blue to green, telling me it's fast charging. But nothing from the phones LED. Also if I place it on a charging pad, color changes as well. I tried both options over night and still nothing. The phone does get warm (usual amount), leading me to believe it is charging the battery.
Holding the power button - nothing (no vibration, no moto logo, no LED responce)
Holding power + vol down - nothing ( = )
USB to PC - phone is not detected at all (I have ADB and current moto drivers installed)
I opened it up, and everything seems to be in order. No loose connections, no water damage. I checked the battery, and it reads roughly 2.5 volts across each pair of pins. Should it be reading 3.7-4 volts across each pair?
I unfortunately don't have another phone to check the MB, battery and LCD against.
I don't have a SIM installed in it, but I doubt it makes a difference?
Any ideas or advice would be greatly appreciated! Thanks-

Quite low for li-ion/-poly, I don't think it ever sees 3v or under in normal circumstances. It might be well into "damaging the battery" territory at this point, and it should certainly be higher after charging it for a while...might be a goner.
Have you tried removing the battery completely and running it off the USB cord? I would expect it to, if nothing else, bring the screen up complaining of a bad/missing battery. That said, I've never tried unplugging mine to see what happens, so no real idea.
I would suggest trying to fabricate a factory cable (which would provide power directly, ignoring battery status), but I don't know if post-OMAP Motorolas are physically configured to use them. If they aren't, it'll do nothing at best and burn up traces at worst : \
Also, holding Vol - while plugging it in should bring the boot menu up, regardless of available battery charge (therefore serving as a quick test to see if the power button is the problem). But that might go out the window as well if the battery is deader than a doornail.

It doesn't. When I fresh-install a ROM, I remove my SIM card to make sure none of my data gets used before I can turn various unwanted syncs/auto-updates off. The phone doesn't care at all, and nowadays Google isn't too whiny about a missing SIM either.
Hello guys.
Sorry for reviving an old thread, but I have similar problem with my Droid Turbo. During the replacement of the battery and speaker, I noticed oxidized resistors near the proximity sensor (which wasn't working since the purchase of the phone second-hand). I have cleaned the oxidized residue with ethanol and assembled the phone. After pressing the power button, the touch buttons light up and phone was vibrating every 20s but the screen was blank. So I disassembled it again to check all the connections but everything was fine. Since then, the phone won't even vibrate, just heats up a lot after holding power button. I have tried both batteries, speakers and also powering the phone without battery (only power cord connected). Both batteries are shoving around 3.8V.
Do you please have any suggestions how to fix the phone? Or should I assume that the motherboard died?
Thanks
