[Q] Samsung GalaxyS2 won't power on

Hi everyone, I appologize in advance if this has been posted and resolved, but I couldn't seem to find anything after numerous searches.
I have a Samsung Galaxy S2 that I have had for JUST over a year (i think June 30th) Everything has been fine, no problems and today I was on it, working fine and then all of a sudden it shut off and then started to reboot. Only when it powered back on, it showed the black SAMSUNG GALAXY SII powered by Tmobile start up screen, then went black, then the startup screen appeared again, then went black...repeat.
I did a battery pull for 2 minutes, same thing. Did a battery pull for 1 hour, same, I left it on the chargert for 4 hours and while on charger kept blinking on and off but now only the grey battery (even now off the charger)
It has never been rooted, or updated or anything like that. There is no water damage at all.
I have a wall charger for the battery only and an extra battery and have tried charging both batteries with that and still no luck.
I have also tried plugging it into my computer to see if it would boot up that way and nope. Still just the on and off dead battery, not even the startup screen.
HELP PLEASE!?

power shortage?
Has there been any kind of problems with your electric house system? that happened to me once, and it was due to a power problem at my house, it basically blew off my battery. Forget about battery pulls. Go to a store and ask them to lend you a battery for a second. If it powers on fine, it's the battery. If it doesn't i think you should get yourself a new phone, or try to get it fixed at the customer service. Sorry for the bad news man...

Nope, no problems with electricity, and neither of the 2 batteries will work!

P6810 suddenly won't turn on

Anyone come across this? I put it on standby last night after reading a bit of my book on it, and it had around 50% power remaining. This morning, it was totally unresponsive; pressing the power button does nothing at all. I've charged it for 12 hours in the meantime.
I've done the following all with and without the power attached:
- Pressed and held power for 15 seconds through to a minute
- Pressed and held volume up with power to attempt to get into recovery for up to a minute
- Pressed and held volume down with powerfor up to a minute
- Pressed and held power while touching screen (read that one off another forum)
I guess potentially it could be on and in a crashed state and unresponsive to the power, so maybe in a weeks time when it runs out of juice, I'll be able to charge it and power it back up, but in the meantime, I'd welcome suggestions.
A few weeks ago I updated it to the official ICS build that was released, but did the update myself rather than using KIES, as KIES didn't even recognise my Tab's firmware original version. It's been absolutely fine before the update, and since. I only mention it because I've read about the Samsung build of ICS being prone to self bricking itself, but I couldn't determine what the symptoms of this vulnerability were.
Thanks for any help offered,
Will

did you try connecting USB cable and plugging it into your PC? did u get any activity? can ADB recognize your tab?

I think your tab just ran out of juice and the battery's protection circuit has kicked in. Try taking it to an electronic shop and plugging in different chargers preferably one with an output more than 2.1 amps to kickstart the charging. Plug it in and wait till the charging animation starts.

Had the same problem while on holidays. Once the battery goes below a certain level, you won't be able to charge it through USB any more. Instead you need to use the wall charger.
I think it's bad enough that the 7.7 doesn't have a micro USB port, but things like that are just stupid and Samsung made a big mistake here. It don't think it's the same with the newer tablets though. It's also not possible to just buy cables or chargers for this strange Samsung port, so when you forget your wall charger at home at some point you won't be able to use your tablet any more.
As long as you charge with the USB cable early enough, you can avoid it though.

A few months ago I experienced the same thing, the Tab just wouldn't turn on anymore.
I tried all there is without any luck.
Contacted amazon and they replaced it with a new one in less than 48 hours.
So far not Problems with the new device.

I have the P6800 and this morning I took it off charge. Put it into standby and only used it for about 20 mins then left in standby all day. It had about 95% remaining when I did so.
Picked it up this evening and the lower left area of the screen was warm and it would not switch on. Didn't think of the ADB idea but will try this next time but I had to reset it and when it powered on tonight after the reset, it was down to 15%. Within about 2 mins of checking stuff it was down to 3%.
Something is running when it is in standby but as I can't switch it on I can't check with BetterBatteryStats or CPUState to know what is wrong.
It does this every day. I am tempted to do a factory reset and reinstall only limited software.
Dave...

I see this thread is a little old but this has just happened to my P6810 too. A pity nobody reported back what the end result was.
My device had at least 95% battery last night but today I can't get it to respond at all, I've tried the wall charger and still nothing.
Anything else someone could suggest for me?
Edit. I tried getting anything from it connected to my PC but it couldn't find a device there. However I then tried it on the wall charger again and now get a blue battery icon, quite big, with a five step animation indicating that it is charging.
No idea how it went flat as the battery on this lasts a long time assuming the screen isn't on. When it boots properly I'll have a look at what the most recent apps I installed were as it has only done this once. Before this it has been perfect for the three weeks I've had it.

This is the infamous Sleep-Of-Death issue that is randomly experienced by myself and other users here, usually happens when WiFi bugs out due to weak signal

hhmmm, interesting.
I was having trouble with wifi just before this happened. Both my GS2 and this have been claiming to connect to my wifi but aren't actually getting an IP address from it.
I can't remember if it was last night or the night before but I manually set an IP address, the signal strength is fine as my abode isn't very big.
After it has recharged I'll have a poke and see what I can find, thanks for the reply.

So my device seems to be working fine again. It had gone SO flat that the date and time were incorrect!
After I could power it on I had a look at Better Battery Stats and nothing looked wrong so I have no idea what happened. None of the apps I'd installed the day before it played up had long wakelocks and weren't running when I turned it off.
For reference they were:
My Tracks
MyTrails
Google Earth
AndSMB
I'd turned both of the GPS tracking devices off before I turned it off for the night.
It hasn't played up since but it hasn't been long so I'll see what happens.

Yeah, the sleep of death is incredibly annoying. Honestly, the GTab 7.7 is a **** device. Samsung made way too many mistakes and won't do anything to fix it.

A similar thing happens to me every once in awhile. The way i check to make sure everything alright is to see if it boots into download mode. I just leave it plugged in for a couple hours and it eventually comes back on.

this is why my 7.7 is the last tablet/phone from Samsung i'll never trust them they are just bombarding the market with new devices and leaving the old ones to dust

^thats what I thought too but that gs4 is really tempting. I've heard worse about HTC in that regard anyways so that why I'm not going with the one.

Finally.. i bought Sony xperia Z.
I'll sell my galaxy tab 7.7. I.m very disappointed with samsung.

Unbelievable! ... this trick still works ... thank you very much for you help ...

^^ yo, this 'trickle charge' trick did NOT work on my (long) dead P6800... any other suggestions??

Quite strange because my Samsung GT-P6800 tablet was fully charged, it went completely blank dark as if it was off. To my amazement, SMS keeps dropping and calls kept coming in. Yet it is still as blank as though the tab was off. I pressed the power button and the volume up bottom for it to reboot. It rebooted without the screen coming up. It has been blank for two days now. What could be the cause? And what possible solution can be given?

[Q] Phone Constantly Turns off

Hi guys,
I recently ran into this problem after I woke one morning to my alarm clock blaring for about half an hour, the phone was pretty hot but not unbearably hot. I took out the battery and left the phone to cool down til trying to boot again, when I did the phone booted fine but it soon shut off again 5-10 seconds into loading into android. I assumed the heat knocked the charge out of the battery / something went wrong with the reading of the battery (as it read like 85%) so I just plugged it into the charger and left til it said it was full. It doesn't shut off by itself and works fine while on the charger regardless. But as soon as I unplug the phone dies within a few seconds. So I turned off the phone and let it charge overnight, woke again to the same issue and the battery reading 85% again. Before I booted back up though I tried the "Wipe Battery Stats" thing in CWM hoping that maybe it would fix it after I fully charged but it made no difference. Also I found that the phone is able to run off the charger when I severely underclock it to 250MHz but obviously it's too damn slow for every day use at that speed. As soon as I clocked it up to 480MHz it had the same issue again. I forgot to mention I was rooted with CWM, unlocked bootloader and on stock rom. After this I decided to revert to my pre-root back up rom from CWM and I still had the same issue.
The final thing that seems to make it work is removing the sim, I tried booting this morning without sim and the phone functions flawlessly even while under a heavy stress test without turning off. So I tried inserting another sim, this one not active. Issues start up again...
Any Ideas guys? Seems to me like if the phone is pulling "too much power" the phone auto shuts itself off. But then the SIM thing perplexes me, not really sure how it all affects.
Lastly, do you think I can still claim on my warranty? I've had this phone for just under a month and it's still in perfect condition... I really don't want to switch back to my chopped and screwed Motorola Flipout. But atleast that thing could handle the overheating pretty damn well. Also I didn't get this on contract I bought it outright from a reseller as a prepaid phone.

In the Netherlands, the warranty for a phone battery is set to six months by law, just contact HTC, and find out.

[Problem] HTC Inspire will not work at all HELP!!

Hey all, I just got through with this hurricane sandy business and now I find my phone not working at all. First off I'd like to say that there is no water damage to this phone and it is NOT rooted. The problem is that it just won't turn on at all, and won't charge when I try to charge the device. The day before I charged the phone and it worked fine. I can provide more details if needed but I need to find a solution to this.

Did it run down on battery completely before it did this? You might need to charge it for a bit before it turns on. Also, see if you can get your hands on a spare battery to see if it's the battery's problem. I would also try removing the battery and putting it back just to make sure it wasn't jostled loose.

Two days ago I completely let the battery drain on its own because it was draining faster than usual and I was using it very minimally due to the lack of phone signal during the power outage. And yesterday I charged it until it was 100% in the morning and at night I charged it again until 100%. Before I went to bed, I turned off my phone and it was 90% and when I turned it on in the morning it was at 77% (which I thought was weird since the phone was not even on). Now the phone will not work at all. I took the battery out and everything. I even tried turning the phone on while trying to charge it (but it would not charge). The only feedback I got was that it vibrated when I tried turning it on this afternoon and after that was nothing. (it would either get stuck at the AT&T bootup part or I would get no display at all)

And nothing happened to it in between at all? That's very odd. The only thing I can think of to try is another battery.

Please post all questions in the Q & A section. Thanks! Thread moved.

Nothing I can think of. It was fully charged by 9PM the other night and shut off before I went to bed. Next morning the batter is nearly halfway drained for no apparent reason. I think I will get another battery to test.
Also I let the battery sit out of the phone for a few days now and the phone still does not work.

Get a hold of a charged battery, then after 1 hour with no battery in the device, replace the battery remove the SD-Card and the SIM-Card, replace all covers. Reboot your PC and go to firewall tab in the control panel and turn of your firewalls, then reboot your PC, then using USB data cable not a charging cable.. with your device being OFF conect to a USB connection in the back of your PC, if it's a laptop use the one next to the intranet connection. Then wait about 1min. If nothing happwned, hold the volume down button then press and release the power button. if nothing happened, hold the volume up then press and release the power button. If nothing happened do the samething this time by holding both up and down volume buttons. If nothing happened with your device connected to the PC go to MY Computer tab right click on C>Properties then go to tools click on check disc tab check mark both options then restart your PC. Before windows tour OS starts, your PC will go through a self check. let it do its thing. it takes a couple of hours. then after its down check to see if it has seen your device. if not then do procedures above once again. GOOD LUCK.

Okay so I finally got it to turn on but in order to charge it, the phone must be turned off for some reason. Also, the touch screen is not working, even after I did a hard reset and erased all my data. I'm not sure if it is a hardware issue or a software issue because the display is working fine.

That same thing happened to a friend of mine. She took it to a technician tho and they sorted it out for her.

Hello every one, this just my first post here, but I have been follow the forum very very close since some days ago thanks to Mustaavalkosta and his new CyanogenMod Rom here:http://forum.xda-developers.com/showthread.php?t=2533007&page=283.
I am having a similar problem with my HTC Inspire, here is my story. I bought it like it a year ago, the first thing I do was to rooted with AAHK and install CyanoyenMod cm-7-20130301-NIGHTLY-ace. Everything works just fine till a couple of months ago. One night I just leave my Inspire and go to sleep, the next morning I wasn't able to turn on, not charging, not turn on. Was not the battery because my brother has another Inspire and I check with his battery. I just leave the phone without the battery and Sim and SD for a day and them come back again, but at next day the same occurs. I try all that time, vol down+power. voldown+volup, every convination but nothing works. So I decide to dissensambly my phone... in the process I broke the ribbon flex cable http://www.ebay.com/itm/OEM-HTC-Desire-HD-Inspire-4G-Camera-Socket-Keypad-Membrane-PBC-Ribbon-Flex-Cable-/320925341841?pt=US_Cell_Phone_Replacement_Parts_Tools&hash=item4ab8a41891 The phone was in parts on my table like a month till I was able to buy and recieve the ribbon (I live in Colombia). Finally the ribbon arrives 3 days ago, so I assembled the phone again and...magic! the phone turns on. My next step was install the Mustaavalkosta Rom that I mentioned before.... but, yesterday, my phone was dead again. So a try all steps again, put out the battery, Sim and Sd... and again try all the combinations of buttons, but nothing works... So I do it again: dissensably again my phone: Only disconnecting the display doesn't works... I have to disconect the display and the ribbon cable, assembled again and just turn on again.... Now I am waiting for the next black out...
I know is a weird behavior, but may be some one can point me in some direction to fix it.. I am not a developer or anything like that, but I like to investigate and solve problems... any help will be wonderful.
Cheers!
PD: I dont have any apps installed, just trying the Rom as it is.
PD: The next time it happens I will try the niavaran advises.

S6 immediately turns off when unplugged

Hello.
After falling to the ground with my S6 in my pocket I noticed it was off. At that time I thought I just ran out of battery even tho it didn't show the zero battery logo. After plugging the phone the battery logo showed and it started going from 0 to 94/95 in a matter of seconds (like 5% per second). I turned the phone on, it charged normally from 94 to 100 and after unplugging the charger the power was cut - immediately turned off.
It does this every time I plug it in: "charges" stupidly fast to 94%, turns ON and works normally until I disconnect the charger.
Do you guys know what the problem is? I find odd if the battery is dead because it went In for service 3 or 4 months ago and they replaced almost everything except screen, camera, back panel and frame. I would send it again to service but I rooted it so Knox is cracked.
Maybe because of the fall I took the battery cable was disconnected?
Thanks

Certainly sounds like a hardware issue because of the drop it took. Now it is charging but obviously erratically, could be the charging daughter board or the ic that needs replacing. Either way it needs to go in for repair, id try and get some quotes

I just find it weird because the phone was in my pocket when I fell to the ground. I see all the time S6's with cracked screens almost destroyed but working well. My S6 has no external damage.

The only way you'll know for sure if this is not a software issue is to factory reset or flash Stock firmware, it very well could a connection has come lose or some sort of damage to the charging part of board if you continue to have issues.

Sent to repair and they replaced the battery. Since I live in Europe Knox 0x1 wasn't an issue.
