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.

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, sim card and memory card 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 (still flashing "dead" battery now off the charger)
It has never been rooted, or updated or anything like that. Factory settings other than downloaded apps. haven't downloaded anything in weeks
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.
I tried holding the power, home and volume (tried up and down both) and nothing happens, just keeps blinking the "dead" battery, even tho it's fully charged
HELP PLEASE!?
Given it's you haven't rooted the phone/run non-stock firmware or messed with it in any way, you'd be silly to try anything like that to try and fix it now (not that anything like that would work anyways by the sound of things).
Send it in for warranty service, assuming it's still covered by warranty. If not, have it repaired by Samsung/a Samsung authorised repairer or a mobile repair shop.
I think they only come with a 1 year warrenty I believe, I can't remember and if I have one its through Tmobile and not samsung. I got the phone a year ago, I believe on June 30th! GO FIGURE RIGHT!?
And, I don't think anything is going to be open today at all given it's Independence day.
Take it to a local mobile repair shop in that case. Will probably be cheaper than an out of warranty repair by Samsung/authorised repairer. If you bought it through your carrier, call them in the first instance & ask them what the go is re: warranty.

I was affraid of that. I just wish I knew what possibly happened!?
Just sucks it's a holiday and I have to wait til Thursday.
Without opening up the phone & having a look, who knows what/why happened (irrelevant anyways). Wait till holidays are over & contact your carrier re: warranty, if no warranty go to local mobile repair shop.
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 bet another battery works, this battery proberly needs some boosting to get to life again... after boosting it starts charging again...

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.
Hi,
today my I9100 froze while in the browser. It didn't respond to any touch or button activity. So I removed the battery and reinserted it, but the phone didn't boot up. There was nothing, a black screen, no matter which buttons I pressed.
I tried the Download Mode, Pushing the Volume-Up/Down while plugging in the USB cable. The battery is fine, I tested it on another phone.
The phone was rooted with cm-10.1-20130606-NIGHTLY-i9100. It does not matter if a SIM is placed or not, still no response from the phone.
One odd thing tough: The phone gets warm in the right corner, near the flashlight when the battery is inserted for a while.
Can I do something or is it dead?
Replace motherboard; service centre - new motherboard (most expensive option), source 2nd hand motherboard from 'donor' phone (with a broken screen, etc; search online) & either replace it yourself or pay a local mobile repair shop to do it (cheaper option).
And if your warranty is good, you could always take it to a service centre & play dumb (obviously they're under no obligation to repair or replace it under warranty tho given you've voided it).

Wouldn't it be have to repaired in order to determine if a custom ROM was used? The phone is not showing any reaction at all, so I guess the only way finding out is reading the flash chip itself, is that possible or is this the normal case?
Anyway I purchased a USB JIG, just to be sure before I give it into repairs.
They might be able to tell. You might get warranty service. These things are never guaranteed either way. Take it to a service centre & find out.
Edit - Jig has 0.00000001% chance of working, but try it anyways. Heat around camera & no life = dead components on MB.
Similar or probably the same issue

My phone is a I9100, rooted, running CM 10.1 Nightly (I don't remember which exact version but definitely not the latest nightly). My phone was in my backpack along with my laptop. When I tried to use it, it remained unresponsive so I turned it off by holding the power button and then turned it on again. It showed the "Samsung Galaxy SII" boot logo and was stuck.
So I pulled the battery out, waited for about 15 secs, put the battery back in and turned it on - no reaction. The phone won't turn on, my computer doesn't detect, not charging. The service center says that my Mobo needs to be replaced.
I have ordered an USB Jig but I'm not sure if it will work. Did you try the Jig? Did it work?
My phone does get heated up near the rear camera even before it died. So not sure if it really is a fried mobo and bootloader failure.
If a service centre has told you its a dead MB, a jig ain't working. Save your time & have it repaired now.

He could maybe try the jig 6 times a day for 6 months to see.
He either didnt read your earlier post or doesnt want to accept reality.

I know the reality. I have ordered a Jig and just wanted to know if it worked for the other person who had a similar problem. Thanks anyway for the time to respond!

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.

Good luck my friend. Sorry to hear about your phone.

So a few days ago, when I got up in the morning for work. I noticed my phone was off, even though I leave it on the charger turned on.. Turned it on, and got a message , the phone was powered off because it detected it was overheating.. Weird? While coming home from work, I had it plugged into my car charger and it seemed fine.. Was up to 69% once it was unplugged, it went down to 49% in 10 minutes.. Put the phone back on the charger in the house, and after a couple of minutes it powered off again.. That same evening went to use a different charger from the wifes Samsung work phone.. The phone would not charge, but would charge hers.. I tried a different charge block and her power cord.. it would show for the phone to reach 100% from 61% 3+ hrs. A couple of seconds later it was not charging.
Ok, tried a different charging cord, and my wife's charging block.. Time to reach 100% 14 hr 57 min..So today I took it to a Samsung repair center not far from my home.. They told me, the phone would not connect to their computer so they could diagnose it.. it was charging fine, so the told me the main board was bad.. They are ording one and will install it next Tue. I never had a issue with my other Samsung phones overheating, or needed to have the main board replaced..
I will say this.. Best Buy is suppose to be a Certified Samsung repair center.. But what I found out, they only service their Flagship phones.. I asked Samsung directly. when I called them first about the overheating issue, before bringing it into them.. Best Buy does not have all the tools to fix all their phones. But they do have all the tools to fix all their flagship phones???????? I find that odd for sure.
I purchase this phone, because it suits my needs.. I have always have flagship phones, but they are not needed for me at this time.. I'm was so pissed about this issue, and first getting alot of running around from different sources about this issue. I was almost ready to trash the Samsung and android all together and go Iphone..
Best Buy is a certified Samsung repair center. It is posted on their website. They just seem to do their high end phones. They also are listed as which devices they fix. Which is Samsung latest flagship phones S9+ and up.
I brought my phone to a actual Samsung repair center. The new board for my phone will be in next Tuesday.
When I started to read this I was constantly thinking this is a battery issue because its charging is so erratic. Now I wouldn't normally question the repair centre but I'm not certain how the main board would cause this. You mention charging a lot but not if the device can be powered on or used. If it can then theres no way there is a main board issue. Virtually all Samsungs have a secondary board which handles power and since your issues seemed power related, I would have thought that would have been culprit number 1. Anyway, I hope they informed you about data loss? The mainboard contains the storage and if they say it won't connect to their computer and you can't power it on for a cloud back up then you will lose all data.

The phone powers on and off just fine.. I purchased a new charger as I had mentioned I think my other one was overheating because of heavy use.. They said the main board and charging port will be changed. The main board because it will not connect to Samsung's computers fo they could diagnose the issue.. I'm not worried about losing any data, as all my stuff is backed up...

Fair enough. Good luck with the repair. Hope it fixes the problem!
Phone fixed. Mainboard, and charging port new.. Charges better, than it did when new..
Hi, did you still have this problem ? I was wondering about buying the samsung A52s or M52.
