Hey guys, was using my SII a few hours ago, and I put it down at ~48% battery life. I had it charging off the USB of my PC. I don't have Samsung Kies installed, or anything. I was purely just charging it, on stock rom/bootloaders/no-root.
I went to pick up my phone a few minutes after, and all the sudden the phone won't turn on anymore.
I've tried pulling the battery, I've tried letting it run through any power still in the circuits, by having the battery out for 30+ minutes. I tried the "pull out battery, hold power for 10 seconds, then pop battery back in," to no avail. I've tried download mode, I've tried using my old Captivate jig.. It doesn't seem to be responding if I plug it in(no heat.)
Any ideas? Going to bring it back to the AT&T store tomorrow to try and get a new one.. I really hope they don't give me any ****. -_-;
Update:
I went to the AT&T store today since they just got a new batch in. Unfortunately, my faulty phone actually wasn't a problem with the phone.. It was a problem with the battery.
Somehow, the battery shorted out the entire phone, and killed it. The reason why I suspect this, is that I asked for the old battery in the new phone they were giving me. Sure enough. That phone is now a brick, also..
Thankfully, they were nice enough to give me a different one and not shove the newly dead one down my throat..
So.. Not quite sure how that happens, but sure enough.. That battery is a Galaxy killer.

You got a dud piece of hardware. Shouldn't have any problem exchanging it.

The only thing you didn't mention is using the stock charger to charge the battery for an hour or so. Did you try that? It could be a dead battery. And once the battery is critically low, your PC can't supply enough juice to charge the battery.

Yes, the USB charging mode on the computer sucks. Its easy to draw a deficit of power running off the computer. I had 8 percent and plugged in via USB and within a minute. Or two it was almost dead, fell to 1% in literally 5 mins. It was almost like it was pulling power FROM. The phone
The stock wall charger is 700ma IIRC. Most PCs can output only 500ma max (USB 1.0/2.0 standard). The 700ma is needed when battery level is really low. So, don't leave home without the wall charger.
I tried plugging the phone into the wall charger, to no avail.
Won't even show the charging screen, or get warm.
Bah! Hopefully the AT&T store will have new ones in stock tomorrow.
Bump.

That's surprising - did they confirm that the phones remained dead even with a "good" battery in?
The charger chip in our phones (MAX8922) has plenty of short-circuit protection mechanisms. (Battery prequalification mode limits current to 90 mA at extremely low batt voltage, and it also has temperature limiting.) So a shorted battery shouldn't have been able to damage the phone.

Indeed, we tried swapping the "new" battery into it. Both of the phones were gone. I never even thought it was probable. Maybe it was just a bad batch? Who knows.
Either way! New phone smell, is great. =P
So I had bought this phone off ebay and when I got it today I tried to turn it on, but nothing happened.
I then plugged the phone in and tried powering it on and still nothing. I tried charging the battery and left it alone for an hour and afterwards the result is the same. Basically when I plug in the phone to the charger, the phone's screen will flash a battery icon as if its going to charge for a split second and then go blank. And then it will flash the battery icon again and then go blank again and it will go on like this for a couple of minutes until the screen finally stays blank.
So as I said even though I leave the phone to charge for a while, it still won't turn on and the only result seems to be that the phone gets warm near the camera. Also I tried to see if download mode works and pressed both volume buttons and I get a brief flash of some words. After doing it for several times I saw it said 'Low battery, cannot download' all in red.
I searched the forum and tried leaving the battery out for a while and also putting it in the fridge to see if anything would happen but nothing. So can anyone help? Is it just the battery?
Could be the battery - if you are on good terms with a local ATT store, try going there and asking if you can borrow a battery from their demo device to see if yours will power up. That's the best cheap way I can think of to rule that out.
Other possibility is a bad USB port. My first device developed a failure at about 2 months - I'm actually on day 5 with my warranty replacement. There is another member here, Moustro I think, who also may have a bad USB port. He and I were wondering if perhaps there was a bad batch out there. I'm not sure what ATT's warranty policy is for items re-sold on eBay, but might be worth checking out...
yeah that does sound like it could be the battery boot loop, take some photos of the battery to see if it is the oem... if it is the oem try a stand alone chager

I live in Canada don't think I'd get much help from AT&T probably.
Also the battery is the original one and not a replacement. I left it unplugged for a few hours and just now plugged it back in and its the same battery icon flashing for a couple of minutes and then blank screen. No charging whatsoever. I tried different outlets and different USB ports on my notebook and its all the same.
I also have an Infuse and charging for that every by every method is just fine so its my SII that's messed up.
If it's any condolence to you, I just bought a brand new GS2 from the ATT store today. The battery was semi-charged when I got it, and when it ran out, I plugged it in and got the same thing you did. Battery is flashing, cannot power it on, even plugged in. I also got the red "Low battery, cannot download".
I spent the better part of 4 hours reloading my apps and email addys, and everything else to get my phone up and running, and now this.
I am going back to the ATT store tomorrow and requesting a different brand new one.
This is my 2nd GS2, because I destroyed my first one in an accident.
Just as dandrumheller was saying. I had simimiar issues where the phone battery would blink on and off even if the charger was plugged in or not while the phone was powered off. The only way I could get my phone to boot to prepare it for warranty exchange was to flash a rom through Odin. But if you can't get it into download mode this wouldn't work.
My suggestion would be to use a different battery. That would let you know if its a hardware issue or bad battery.
hmm...
I was able to to get it to power on last night with what little battery was left. I then plugged it into the USB of my Mac, rather than the charging wart. When I awoke this AM, I have a fully charged battery, and a working phone. I will let the battery run out again completely today and see what happens.
That's great news! I hope it continues to work for you
I would not let it completely run out. Our batteries don't like that. Don't go below 25 percent. I'm glad you got it working. I know you're relieved.

I'm not sure relieved is the right word.
Apprehensive might be better.
We all know AT&T isn't in the best graces with most.
They must be the ***** of Comcast.
Anybody got anymore suggestions?? Can't get it to work no matter what I try.
Call samsung and see if they will honor the warranty? Don't know their rules, but in another thread someone suggested that sale of the phone does not void the warranty.

Max,
Were you able to find a fix for your problem? i bought a SGII from ebay and is presenting the same issue
For what its worth I am able to enter download with NO battery. In fact I ONLY do it without a battery. I just hold both volume buttons and plug in the USB to my computer while not pressing anything else. Without battery.
Thought the OP said he couldn't enter download.... so if that doesn't throw it in download it's more than just battery.

Guys,
I tried this and it worked...
At a last resort, i put the battery on nexus to see if it will charge and DAMN !! it did,, so the battery was not the issue...so i grab a swab with little alcohol then clean the terminals on the battery and the spring connectors on the phone... and voila !!! started charging and keeps working perfectly.
It worked for me, hopefully it will work for you guys.
Glad you were able to isolate the problem.
Sent from my SGH-I777 running MIUI with Siyah
Same problem
Flashing on for a sec then flashing off, buttons flashed too. Phone got hot around the battery. Couldn't have described the problem better
Took some alcohol, cleaned the contacts for the USB connector, cleaned the battery contacts, and booyah, got the charging symbol again! Problem was, I didn't use the phone for a month, it rode around in the front pocket of my laptop bag, and apparently got the contacts dirty. A little toothpick and q-tip fun later, and my phone started charging again. Thanks -

Really? I've had mostly HTC phones and we could run them down pretty low.. I've been running mine down past 10 and it's been fine.. stock battery.
I had the same problem as op. My last resort was to cut the micro usb end of a spare cable and connected it to the (+) and (-) on the phone itself. since the phone booted up, i knew it was the battery. Next, i did the same thing but (+) and (-) on the battery itself while connected to a computer. i held it in place for about 10 seconds. put the battery back in the phone and it started charging again. im sure it wasnt the safeat thing to do, but it worked. Maybe the dead battery needed some kind of jump.
btw. The wires you would be using are the the black and red. and i got this idea from

I believe these are different types of batteries. Not Lithium, but something else. I bought some spare batteries from eBay and the batteries had the same instructions... That it is not good to let them die completely, and charge then preferably when they still have 1/3 charge left.

My SGS2 died on me yesterday. was working all day as usual but at the afternoon when i where to make a call it wouldn't wake. Had 50% or more left on the bats for sure at the moment.
The phone where running the CM9 development rom wich has been running on it since beginning of january Last time i updated it was about a week ago. (Don't think this problem is related to the rom though)
Symptoms:
The phone is totaly dead, no signs of life on the screen. Cannot get in to download or do normal boot.
When I charge nothing happens on the screen, but after a little while the phone begins to get hot betwheen the camera and the battery (where the simcard is)
This video is not mine, but our phone seems to have the exact same symptoms.
I have tried:
Re-attaching the battery, and leaving it whitout bat for a few hours
Starting it with charger in with and whitout a battery
Tried a bettery of a friends SGS2
Pluging it to the computer, no sign of life (my computer does not react at all)
Nothing works
My thought is that this is a hardware related issue. But please correct me if I am wrong.
I haven't tried a JIG yet, will see if I have correct resistors at work tomorrow and make one. But i hardly believe it will work.
Is there any chance the JIG can reset the counter even if I wont get any life from it? or is it first after the flash to stock with JTAG the counter resets?

You're confusing JTAG with USB jig, but it's extremely unlikely to do anything. Considering the phone isn't responding to anything anyway, I also doubt the custom binary counter matters much.

So I figure this is a hard brick tried everything u did and a jig gonna send it to Mobiletech videos for jtag fix after i get paid and hope that works.
any news?
My phone did the same last night.
cm9..
Totally dead, cannot charge. Please any advice would be great. thanks.
You could try a jig, but as per the above unlikely to work. Needs to be JTAG'd/repaired either by Samsung or a 3rd party repairer. Hopefully if you send it to Samsung they won't be able to tell the phone has had non-stock firmware on it as per Oinky's post & fix it under warranty (they may not tho).
This is going to sound odd but check you're display.
Wipe it clean and hold it at an angle against a bright lamp. Look for any small cracks or black lines.
Could the phone be water damaged?
The backup battery on the motherboard also can leak and cause problems like this
I work on the Samsung team at a service center in Norway and these are some common reasons for a dead phone like this
Could maybe be the battery on the motherboard that has leaked, but i guess i won't find out until it comes back from service.
Strange though.. Phone has been fine, just all of a sudden this. Exactly as the op describes..
I put it on the charger last night, had around 20% battery left. In the morning it was completely dead, and a bit hot. Plugged in the charger again, and the charging symbol comes up for a few seconds, disappears, comes back etc a few times, then it gets rather hot around the camera, and on the front side (screen side) and stays completely dead (no charging symbol), until it has been unplugged and let to cool down a bit.
Every time i plug it in, the same thing happens.
I'm traveling, and wont be able to send it on service until after a month's time.
alas, phone free holiday
Hi, my Samsung Galaxy S2 (i777 from AT&T) had been spontaneously rebooting every few minutes in the last few days. (FYI, I am using the unlocked phone outside the US. Currently running Android 2.3.6). I have been charging the phone with my USB cable lately (which might have caused the problem), and it doesn't recognize the device anymore.
When the repeated restarting started, then I somehow managed to delete some recently updated apps/new updates, and the restarting stopped for a while before returning the next day.
Then finally, the power button just stopped working altogether. For unlocking the screen - I now have to either plug in/disconnect from the charger, when it beeps & lights up, and then I can use the phone. I have tried using apps such as: Fix Broken Power to at least maintain the usability, but the app only seems to work after I plug the charger in/out, so it isn't any help.
I guess the power button could've died & need replacing, since the device is almost 2 years old. But before taking the phone to a mobile-phone repair shop, I wanted to check if there is any other option for fixing the issue (without doing a factory reset). Also, please advise any alternative screen unlocking app for using in the meantime.
Thanks in advance!
Replacing the power button is extremely easy, I wouldn't spend the money to send it off. All you'd have to do is take the cover of, remove a few screws and pop the new button in. Takes about 4 minutes.
An alternative is to root your phone, upgrade your firmware to 4.1+ and use either the AJK or STI kernel; they both use Stweaks, which has a slide2wake feature that allows you to wake the screen up without using the power button.

Thanks SteveMurphy! That was some good advice. But since I'm not very technically sound, so I took it to a repair shop. After keeping it for one day, they said that, the power button is fine, but the internal processor is having problems (probably because I've been charging it with a USB cable), and they quoted a pretty high amount for replacing it. What's more annoying is that, the battery went dead since it wasn't charged while it was with them, and over 24 hours of charging (after I got it back) didn't bring my phone back to life. At least before I could use it while it was plugged in to the charger, but now its all darkness. I'm thinking of taking it to my local Samsung Service Center, and I can see it costing a fortune, if it can at all be fixed. Very upsetting.

Hi All,
I was using my phone normally about 2 days ago, then put it back into my loose shirt pocket. When I took it out a few minutes later, I realised that the phone was off. I turned it back on, and while it was on the "Samsung Galaxy S II" logo, I placed it back in my pocket to give it time to boot.
I kind forgot about it later, and when I took it out about half an hour later, I realised it was still on the same screen. Thinking that my phone has frozen, I tried to depress the power button for about 5-10 to shut it off, to no avail. I did a battery pull, replaced the battery but found that I was unable to boot the phone at all.
Thinking that maybe the battery is flat, I tried another 2 more original Samsung batteries that I had with me, both fully charged. Nothing worked. I even tried entering recovery and download modes to no avail. I also tried several other methods described in XDA including plugging in the battery while doing the keypress for download mode, both volume buttons while without a battery and sticking in a connected USB cable, and even my old USB jig. Nothing. No boot screen, nothing on the capacity buttons.
Oddly though, if I plugged in my battery and press and hold the power button for 5 seconds, then leave the phone aside for a while, I noticed that it gets warmer. If I pull the battery out, it cools down. So it seems like turning on the power does "something", but the phone wouldn't boot. Plugging it into to computer doesn't recognise it either. Neither can Odin 3 see it.
Is my phone truly dead? Or is there any possibility of fixing it?
Thanks.
Replace motherboard - Samsung service centre (expensive option), or source a 2nd hand board online & either replace yourself or pay a local mobile repair shop (not Samsung service centre) to do the replacement for you (cheaper option), or new phone.

So it sounds like a defective mainboard to you? Mm.. If so I'd probably go for the 2nd or third option. Already bought a new phone, but I do have 2 SIM cards (one issued at work without a phone) and I would like to be able to use my S2 (currently using and aging Motorola Q9H). Plus there's some data I had in the internal memory and the phone does have some sentimental value.
I'll go source for a board I guess... But the flash memory will be lost with a new board wouldn't it?
Thanks for the advice!
Given the majority of components that would cause a phone to simply die like that are located on the motherboard, that's the fix. As to what component(s) specifically died, nobody here could tell you that because we don't have the phone open in front of us with the gear to diagnose.
Some repairers in some countries have been flogging a 'we can just replace the individual component(s)' fix lately (as evidenced by people making threads here saying they've been offered these fixes), but this is a very tricky job that not even Samsung service centres attempt; basically, if you want it fixed guaranteed first time without the risk of potentially double paying (for the first fix that doesn't work), you replace the board.
Yes, you'll lose whatever data is in the NAND on the existing board, that's not really recoverable, but a company which specialises in recovery of data from dead HDD's may be able to help (I haven't seen a single thread on here in 2+ yrs where someone has been able to get this done though), expect this to be very expensive if it is possible.
I see...
Worth a shot I guess. Samsung's CSC aren't really an option here past warranty, and the professional recovery firms here charges sky-high rates. I'm looking at motherboard replacement guides for the i9100 for now, may look for a 3rd party repair shop if all else fails. Pity, it was a great little tool. I had it running on a smooth JellyBean 4.2.2 =\
I had this exact problem, what my case was that the battery died completely.
I bought a new 1800mah battery and it works fine. I can't boot with the original old one anymore, it is 100% dead (still has some juice in it)
but if you can't use other batteries (that work with the s2), then I guess your nand is dead.
