[Q] Samsung Galaxy S2 I9100 won't turn on - Galaxy S II Q&A, Help & Troubleshooting

Hi Guys, first post in here, and I have searched the problem and tried a few things but my problem seems to be slightly different to the usual "not turn on" problems.
Basically, the phone refuses to turn on, but unlike the other cases I've seen, when put on charge the battery charge icon flashes on and off the screen.
Sadly I have no history with the phone, it was given to me a few days ago, and the friend who gave it to me bought it in a box of electricals in an auction.
It would be nice to get it going just to have as a spare.
What I've tried so far:-
Hold Volume down and press On (Holding for at least 10 seconds)
Hold Volume up, home and press on (As above)
A "fix" I same which involved taking the battery out for 30 seconds, then plugging it into charger, then putting the battery on and switching on.
Taking the battery out for 24 hours, then trying the Three button salute.
Has anyone got any more ideas, or shall I just go to the nearest lake and see how many times I can make it skip before it sinks
Thanks in advance for any help you can give

You won't be fixing it without spending money, so...
1) Try a new battery first.
2) After the battery, if you're really that keen & want to spend another 10-15 bucks, try replacing the USB/board port. KeithRoss39 has a guide in the general section (search for 'replace USB charger board'/similar), has all the info you need to get it done.
I'd bin it if those two things don't work. You'll have already spent $30-$40 at this point (assuming you paid for the other battery). If you have to do something like replace the motherboard, there are plenty of decent phones you can buy new for that kind of money 'just to have as a spare'. Your biggest problem is you have no idea about what's happened to the phone previously, and unless you're experienced with diagnosing electronics like this, you're guessing at best (and taking it to someone who is costs money unless it's a friend).

[Q] Could it be hard bricked?

I know many have gone on saying, oh I hard bricked my phone, etc, but turns out it was soft bricked. So let me say, I've soft bricked my phone many times and recovered it using Odin trying out different ROMs.
So what happened tonight is I was using my phone, browsing the internet when it locked up, screen stayed on, no response. - Sure, no prob, just restart, it's happened before. I held down the power button and shut it off. But now it won't turn on again. Battery is fine, I tried it in another phone and swapped the other phone's battery into this one.
Plugging in a charger doesn't do anything. I can't check Odin, cause it there is absolutely no response from plugging it in, removing battery, plugging it in again, holding down power buttons while plugging in and inserting battery, etc. I've tried many ways of getting it to power up, nothing seems to be happening.
I was running Bionix 1.1, with no problems for a couple months, so I really don't think the ROM did anything to it. Think my hardware just took a dive? It's really strange, and I'm sad. This phone is just about to hit 6 months old.
Do you guys have any other ideas of something I could try? Maybe I'll even open it up and take a multimeter to it to see if power is at least going through the phone.
Help!
Thanks.
Hmmm... Maybe Try the jig and see if it responds (check the sticky on that)
If not, Then check with a multi-meter and check continuity check the usb, check if there is voltage passing through battery contact (continuity). this all fails, then i would dis-assemble and check components,
http://forum.xda-developers.com/showthread.php?t=908211
here is a link on how to do that. The nice thing is you can check easier when all assembled. Also, If you do figure it is a component then Globaldirect.com does sell the pieces so you can replace.
Not much help but without really seeing the phone it is just guess work (and even seeing the phone it usually is guesswork as well )
Thanks Oka1.
I don't think the Jig is going to help in my situation. I'm not having an issue getting into Download mode. The phone won't power on at all. If I saw an image on the screen at all, I'll feel alot more confident. But nothing at all is showing.
I'll figure something out. I'll probably call up Samsung when I get to work tomorrow and pull the phone apart.
Thanks.

I've been in this spot before. Try, pull the battery, plug in the phone, hold the three buttons and at the same time push the battery back in. Should do the trick. It's been a long time since i've had to do it but I think those are the steps.
pull the battery and only hold down the volume keys, plug the usb in and put the battery back in...download mode..
Well... it's working again.
I did nothing other than pulled battery, sim, memory card and left it all apart overnight. I don't know what this causes, but after 8 hours, I put it back together again and it started working.
I had tried this over a 3 hour period before going to sleep and it hadn't worked, but somehow overnight worked..... sooooooooooo strange!
But thanks so much for the suggestion guys!

[Q] X10 Mini Switched Off, won't charge/repair

Hi all,
I've spent hours researching and nothing so just looking for new ideas.
The last few days I've been running official SE 2.1 and today it started force-closing many apps. I restarted the phone a few times and that didn't fix it. So I restarted again to go into recovery and switch ROM. The phone switched off and won't turn on. It said it had low battery life if that's a part of it. The phone will not switch on, it will not charge with any combination of with/without SD card, SIM card etc.
1. SEUS and PC Companion will not repair it, they don't see it.
2. Laptop/PS3 don't see the phone.
3. I left the phone connected via the wall-charger for over 2 hours at two seperate occasions uninterrupted an nothing.
4. The phone shows no LED. Not even the quick-flashing red LED when the battery is extremely low.
I searched every SE site where this is discussed and no help, I've tried everything. I emailed SE and they said it would be better to send it away. I note that they charge a fee if they can't fix it. (It's within warranty though) and my phone is unlocked, debranded and shows various mods typical of users' phones from this site and the warranty says if SE find user mods they phone will void warranty. It may not switch on and neither the network or SE may find the mods which may mean I get past OK, but besides that, is there anything I can do myself? Thanks.
REPAIRED MYSELF
After hours and hours of research and effort, 5 minutes after posting this thread I fixed my phone myself. I hope though that this will help others out there. As with everything like this, especially on this site, these are user mods and frequently delicate or dangerous - you do them at your own risk, and could destroy your device or warranty. If you haven't rooted/flashed many times or don't know what they are, you do not know enough to do this. I say this to protect you, trust me.
If you take off the back cover, above and to the left there are two RUBBER coverings. I used a pin to remove the LEFT cover. You see the power connector of the phone to the battery. Use the pin, carefully and at your own risk, to remove the white part by gently pulling back and up. It's stiff so try a few times. You see 3 wires connected to the white tab. I clean the white tab and metal connector with my finger, re-attached the white tab, you must do that firmly or it won't connect, try again and again. Try the power button on the phone when you have it connected to laptop/pc/etc. and you should see the the red LED gently indicating it's slowly returning to power.
That was a hardware issue it seems?
I really don't know...I've seen other's recommend giving your phone a jump-start with a battery and connector but I couldn't find a connector, and just tried cleaning it with my thumb (no obvious cleaning needed, but I tried) and it did the job...strange. I'm sure this info. will help the next person who gets lost. It'll save time and perhaps money. And us guys around here like to fix things ourselves anyway...

[Q] Samsung Galaxy S2-i777 Spontaneously Rebooting - Power/Unlock Button Not Working

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.

lumia 800 overheated and failed to sustain reboot replaced with new battery all keys

all key combinations have failed to produce boot and screen but the vibration responds quickly to the sequenced key combinations. no password issue always seemed to need a reset and extra attention but worked fine until left in partial sun through draped window and was powered on without a cool down. I heard a hiss and though the battery was discharging itself, tried when cool nothing so I put new battery in got a battery icon with low level and would not progress in power from there would not accept the charge . I charged with a new cube led usb charger and data cable overnight got the right results noted above but this time no icon just black screen I dont know what the power level is. I have tried three days charging nothing computer and wall. Tried to make phone vibrate and plug back in no. Windows phone one after mango, have lumia 710 zero problems removed battery twice to reboot phone twice in three years no biggie. Mango 7.5 on 710. want to use 800 as a data phone only would not trust it (mine anyway) for communication. Paid good price for it would like it to work again. Should I try powering it up for a few days? Oh phone always put on a surge protector as all my phones are. I once put phone under my pillow and a few hours later it booted screen came on. Have read people putting hair dryers on them I dont think thats the way to go got me here in the first place. very wonky phone it will and then it wont. I thought maybe usb connection damaged but obviously it is accepting some power and phone responding normally and readily to various key combo prompts but no boot and screen. How might this phone be repaired I would like to know what specifically could be the problem a base power or temp for reboot, what parts I could purchase (out of warranty) all parts inside were connected and looked pristine. No evidence of any heat damage. Used another Nokia battery for this phone new. This phone was let to totally power drain and what I have read that is not good for this phone. Maybe it is only accepting minimal power as before dont know but will try to charge another day to see if any activity occurs but would appreciate any help in zeroing in on what the problem or problems maybe, no software updates if no boot and it should do that if anything.
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.

My Galaxy View won't turn on

I've had my View since 9/16. I use it everyday for probably 6 hours or more. Every night I turn it off and plug it into the factory charger. I tried to turn it on the other day and it will not turn on. I'm a geek so I've tried everything I can find on the web and Samsung's site to get it to work. I contacted Samsung and they've sent me a label to send it back to them for their evaluation and price to fix.
A couple questions for other forum members:
1. Has this happened to anybody else?
2. Anybody had the battery die? I've put a lot of hours on mine...
3. Anybody had any experience with Samsung service?
Thanks for any feedback...
Larry
I have not had this happen to the View, but I have had it happen to a few other devices when I used to test devices for a wireless carrier. This can happen when the battery is "too dead". If the battery drops below a vital level then it can fail to start up into the charging boot screen. If it was on the charger, it's possible that your charger failed and caused a parasitic loss to the tablet. This is, perhaps, the worst problem with non-removable batteries. Sometimes you can hold the power button down while plugged in and it will start charging again. I assume you have purchased, or already have, a second charger, to rule out it being a charger issue. To have any chance of this method working, you will likely need to hold the power button for at least 10 min while attempting to charge. Basically the concept is that you are trying to get the power to flow to the battery even while it can't boot the charging screen kernel.
Thanks for your detailed reply. I really appreciate it. And I did try another charger. Didn't try holding down the power button for 10 minutes, but I get your point. I contacted Samsung and they provided a 2nd Day Air return label, which I thought was generous for a tablet out of warranty. So it's on its way to them to evaluate and give me an estimate to repair. I'll post when I hear back from them. Thanks, again, for your reply.
Samsung discovered my motherboard needed to be replaced. Cost $109 including shipping both ways and it seems to be working just fine. Of course now I have to get everything set up again. I thought the price was reasonable - a heck of a lot cheaper than a new one.
