Samsung Galaxy S2 - Wont turn on. - Galaxy S II Q&A, Help & Troubleshooting

Well back again with new problem.
Have just had my phone back after it was repaired only a week ago by samsung; they repaired the software, replaced screen, battery and USB port. Now my unrooted phone, with only usual apps, has again failed on me. Was on the home screen, nothing else running, and it turned itself of. After a minute turned itself back on, held at the Logo, and then turned of again. Now it wont turn on what so ever. Its not got hot, its not got cold, its not been in a room with steam, its been sat in a decent zenus case, in a house with radiators etc on.
I seem rather unlucky with phones, my old Nokia 5800 went into repair 6 times, until I gave up and brought a £10 phone, that I'm having to use again now.
I have tried charging, despite the fact it was still 62% full when the phone went of. I don't do extreme sports with the thing, I barely use the phone, yet it still keeps breaking. Disappointed, because the phones pretty decent, but starting to feel like I don't do well with them.
Rant over.

Update: Just tried after 30 minutes to turn it on. It turned on for about 15 seconds, got into the unlock screen, unlocked, went to the menu screen and it turned itself of. I put the charger straight in, was charged up to 59% anyway, but thought maybe might be battery... But doesn't seem to be.
Wont turn on/Charge again. The phone is fine temp.

What you're describing could be a phone with a drained battery.
So check the battery with a voltmeter and check the charger. One (or both if you're really unlucky) of them could be busted.
Edit: You can check the charger by plugging your phone to your PC and charging it from there. If it works then it's the charger if it doesn't then check the battery.
Is all else fails return the phone to a service center.

Try this-
Take out the battery, then press and hold the ON button for 7-10 seconds (the longer the better). Reinsert the battery, then press ON button to start it. This is a soft reset, and wipes the temporary memory and empties all remaining power in the circuits. This helps on many phones and even laptops that won't start properly or show anything on screen.
If this does not work, try the next step. Again, do as above. But after inserting the battery, do not turn the phone on, but press and hold the ON button and the HOME button at the same time for 7-10 seconds. This is a hard reset, and works best if done after a soft reset. Just be sure the battery has at least some juice in it and isn't empty. If possible, try with another battery if this does not work.

I read earlier about a similar problem and it turned out to be a loose fitting battery. They put some foam or something at the bottom of the battery so that it would stay tight and retain contact.
You could probably test for this by removing the back cover and pushing the battery upwards while powering on.

Thank you very much MichaelAmrs. you saved my Galaxy S2

Awesome Advice
Thanks MichaelAmrs
I have had some serious trouble with my GS2 not working and the latest has been it not turning on. I stuck my battery in the freezer and then did what you suggested and it worked like a charm. Instead of getting it to boot I tried putting it in Download mode and was able to install the Stock ROM on it and hopefully now it will last. But if nothing else at least it is turning on again.

Good luck.

Phone won't boot up

I have a Cingular 3125, working fine for weeks, happened that two days ago, I was charging the phone and transferring files to my computer via Bluetooth, nothing unusual, then it just got frozen, nothing responding, so I just took out the battery to manual reset the device and reinserted it, then tried to turn on the device, but it refuses to boot, no lights at all, also when I attach the phone charger, it doesnt show the usual orange led when charging, but I can feel that the phone gets warmer because the charger is attached and then after a while it gets a bit cooler, just like when it finishes charging, the usual behavior, but again, no lights at all trying to boot it or even attaching the charger, I've tried taking the battery off for hours and nothing also, and I wasnt overclocking the phone... would you say it just died? or maybe someone had same issues and solved it someway? thanks.
try this
OK, I don't remember where I read this, or the exact procedure, but give this a try.
remove the battery, press and hold the red call end key (power key) for 30-45 seconds. insert battery and do a hard reset, IE.. power on holding the 2 top soft keys while powering on the phone.
this method is supposed to clear any mother board issues and reset the phone. It has been a couple of years since I read the procedure so I am not sure if this is the correct way, if it does not work, try the same thing, only try taking the battery out, then put it back in and press and hold the power key for 30 - 45 seconds.
may or may not work, but can't hurt to try.
i had the same problem with startrek which i had bought from eBay
one more advice - try to hold record (notes) and camera buttons and insert an USB cable to your PC, it should enter to Bootloader mode
well, I have dissasembled the whole thing, I havent reached anything, even disconnected the backup battery, nothing, have checked battery with a multimeter and is full loaded... in short, someway the cell phone seems has just died, Erofich, to enter bootloader mode, the phone must turn on, it just doesnt want to start at all, no lights when connecting charger or USB cable... I'm sad because it was working fine with no problems for three months and more sad because it's the end for me to windows cellphones for a long time, I've invested a lot in this phone, accesories, unlocking, and even the same day it died also bought more memory and a neat skin cover and I'm not in mood to invest more in a cell phone so I'll use a spare crappy feature phone.
Thanks for your support.
one last effort
You could try one last thing, this has worked for me with a couple of startreks,
take the phone apart, and take the motherboard out, use a hair dryer to heat the motherboard, don't get crazy with it, but using the hair dryer on the high setting for about 30 to 45 seconds at about 3-5 inches, might revive the phone. (don't heat the battery, just the motherboard)
Put the phone back together while it is still hot (but not so hot that it will burn your fingers) and try to fire it up.
This has worker for me in 3 cases (phones that I bought off eBay that had the same symptoms as you have described)
good luck
big problem!!!!!!!!
I have been struggling to flash (again) the great pro V2 rom, but I always used my VMWare based XP windows version on my Vista laptop. Today I could use a genuine XP Laptop and I could make a connection and start the upgrade!
Sounds good? That's what I thought too, until the upgrade stopped at 70% (and I didn't touch anything), because of a connection error. I followed the text on my PC screen and I finally it started flashing again for a few seconds and then my startrek suddenly restarted, but it stops at the first splash screen! I tried to get my device back to bootloader mode (push 2 soft buttons and start), but no bootloader mode, only the 1st splash.
I solved the problem.

Sudden crash and won't turn on

I've had this phone for 2 months.
I started up dead space, had wifi on and it was downloading the game data.
left the room to clean the kitchen (maybe 20 mins) when I came back the phone wouldn't unlock
pulled the battery and turned it on, phone booted but wouldn't get past the initial samsung logo.
after that it wouldn't turn on at all
I pulled the battery, left it for a few mins, put it back in, tried booting up, tried getting to recovery, download mode, tried removing sim and sd card
is this an issue other people have had? am i screwed? i left it plugged in w/ the battery in on the off chance it didnt have enough charge or something. but the battery logo isn't coming up
Try charging phone for an hour or so.
Question: when you connect your phone to the pc, any reaction on the pc side? Is Odin recognizing the phone?
If you can't get into download mode by holding down home+volume down+ power at the same time, you can buy a usb jig (or make it your self it's not that hard)
Just google for usb jig.
Other than that. I have no idea.
Good luck to you dude.
Sent from SGS II Running CriskeloRom V34.
no reaction anywhere. the battery animation isn't displayed when plugging in either.
can't get into download mode to use odin. i ordered a usb jig (figured it would be good to have it anyways)
the phone is currently plugged in, the battery feels slightly warm but it still wont turn on. i'm hoping it is a faulty battery.
my plan is to go to a phone shop tomorrow and ask to borrow a battery just to see if it will turn on, if not ill try a repair shop. if not that, then i'll start complaining about my warranty to the international seller i got it from on amazon.
Sorry to hear that.
Good luck.
hi if u have a tester test the voltage on the battery -/+ for dc voltage if it's zero u need to shock the battery.
i brought it in to bell and asked to use a spare battery. the girl took it right out of her phone and put it in mine, tried to turn it on, nothing. no download, no recovery, no reaction whatsoever except for a slight warming around where the camera lens is if you hold the power button for a long time.
looks like it's fried. i really hope I can get a return with the amazon seller. i've only had it 2 1/2 months

[Q] Rezound Bricked?

My Rezound is broken
I unlocked and de-sensed it, but that was when the unlock first came out and it's been working fine since, so I don't thing that's the problem.
The phone won't come on, and when I plug it in the charge light doesn't even come on. If I leave it plugged in, then take the battery out and put it back in the charge light comes on for a few seconds, then turns off.
I was at a new years party the night before and I may have laid down on top of it while it was in my pocket, but the water sensors are fine, and I don't remember it ever getting wet.
I notice there are a lot of connections between the phone and the back cover. Is it possible that something could be bent and these connections aren't being made, so the phone refuses to do anything? I tried putting wires across them where they would normally be connected, but it didn't seem to help.
So what do you guys think? Is there something else I can try? I guess if it's totally broken then they can't tell that it's unlocked, so I could try getting a replacement :/
First off, I wouldn't have put any wire across any of the antenna leads like that. Second, if the phone is not coming on with the cover off then you may have another problem. The phone should turn on without the cover. You just wouldn't have signal.
My opinion, try another batter if you know anyone who has one. Or maybe go to your VZW store and see if they will let you use one of theirs. If the battery/phone is too hot the LED will blink orange, once it is cool enough, or full enough to turn on/charge again it will become solid. The fact you get an indication when there is no battery leads me to believe there may be a problem with the battery itself.
with the phone off, pull the battery for several minutes. Then put it back in and plug it in to the charger. Do not try and turn the phone on. If the charge light comes on and stays on, just let it charge for a few hours until it turns green.
I've read of rezounds dying from the battery going completely out. Screws it up somehow. Verizon also has thunderbolt external chargers for 5 bucks. You could use that to charge the battery (it fits), then try and turn it on. If it still won't turn on after charging, put the battery in and try and boot into the bootloader menu (power on and vol down at the same time), from there you can restore your nandroid or flash another ROM if it will boot to it.
I tried leaving the battery out for a few minutes, and then for the rest of the day. No dice in either case. I'll try to get an external charger tomorrow :/
Thanks for the ideas, I'll let you know how it goes.
Mine died overnight. Same symptoms, charging light for a few seconds then nothing. I plugged it in, let it sit for a while (didn't time it, but not more than 15 minutes). Unplugged it, then: held power, volume up and volume down all at the same time. It booted up, as soon as the screen came on, I plugged it back into the charger. Running fine now. Hope this helps someone else.
Went to Verizon today. I bought another battery and ordered an external charger. Swapped in the new battery and the phone started right up
Now I just hope I didn't screw anything up messing with the antenna contacts :/

After getting the new battery, does the orange LED come on while charging the phone when powered off? I replaced my battery after having the same problem and now the orange light does not stay on while the phone is charging when it is powered off. I guess it's no big deal, but it bothers me.

Yeah, it still works just fine. I turned it off just now and then plugged it in to check and the charging light came on immediately.
Maybe the battery is faulty or you got a thunderbolt battery by mistake and the phone is confused? Otherwise I have no clue why that would happen :/
I have them same problem. My phone is completely dead, won't turn on and a orange light comes on for 3 seconds and goes away and nothing happens. What do I need to do?
Sounds like your battery died. Pull the battery and let it sit for a few, then try to boot it back up and plug it in immediately.
I was reading a thread about this last night on RootzWiki. Dude did a lot of testing, came to find out it was ClockWorkMOD keeping a completely dead battery from charging at all. Is that the recovery you have? If so, I would put AmonRa on, try that.
Agreed, almost definitely a dead battery. You can try this:
1) Take out the battery and put it back in
2) Hold down power and volume down to enter the bootloader
3) Immediately plug the phone in and leave it there for 10 minutes or so
4) Reboot the phone now that you have enough power to make it through booting
This should work as long as your battery is completely dead.
My suggestion for the future though is to buy an external charger and a second battery. That's what I did, and now any time I accidentally let my battery die I just swap it out and I'm good to go at 100% while the other one recharges. Also an external charger is the easiest way to fix this if your battery is too dead for the above method.

Also, remember that if you are using Clockwork Recovery for some reason that makes the phone not charge when its powered down. I had the similar issue where i couldnt get it to charge or come on at all, i put in a battery from my TBolt and it turned right on, switched Recovery to Amon Ra (Blue one, not the Red one) and from there it charged no problem!
worked...

this worked for me! thank you!! also to come to think of it, the problem happened after installing clockworkmod recovery. so there certainly seems to be a connection

This absolutely helped me! I'm really liking this Rezound I picked up but the damn thing is also just very temperamental in general. Still a fantastic underrated device overall though.
My wifes d2g did that once. I ended up taking an old charger, stripping the ends off and taping it to the contacts on the battery for 30 minutes. It charged it up and after that it would charge thru the phone again. A lot cheaper than a new battery.

[Q] Evo3D: Ive spent hours troubleshooting a power problem!! Please help!

Its been day 3 of having a phone that refuses to power on..
I went camping over the weekend and had it plugged into (and charging) my travel charger via cigarette lighter and it was working fine. At one point I went to use it and turned on the screen but it glitched out by the screen turning on then off a few times until i left the screen off, gave it a few seconds, and turned it on again and was able to put in my security lock etc. It does that once in awhile and I chalk it up to a computer booting up and my impatience
Well the screen powered off while reading on my phone, and I went to power on but it wouldnt stay on this time. I got a glimpse of the battery and its probably 85% charged, but upon coming home and leaving it on the charger all night I am still with a dead phone.
There is no flashing white/green/red led light a the front, even when plugged in.
Ive tried all the solutions on these forums (camera + power button, camera + power + volume buttons, removed battery, cleaned with eraser, tried different chargers via wall outlets & laptop, and even the cmd & "bootloader" stuff but the request is never recognized..) I really need some help with this, PLEAAAASSSEE!
Ive never rooted (?) or flashed or did anything of the sort with this phone, its pretty much stock.
**I just tried putting the battery in after a few min, and as soon as the pins touched and the battery was in, the back lower camera light flashed on for a few seconds and then shut off. Still no power to the phone though
I cant find anything close to my problem so I hope someone out there has a new & successful suggestion!!
Thanks all!
Have you tried a new battery? It truly sounds like your battery is gone and doesn't hold (much) of a charge.

[Q] Rezound dead?

Hello!
Earlier tonight I received a text message and then my phone died - I knew the battery was nearly dead.
When I plugged it in, nothing happened - no orange LED like usual.
I let it sit for a while and still nothing.
Eventually I pulled the battery and put it back in and still won't power on.
Pulled the battery again (left it out), left the back cover off, and then plugged in the power.
After about 2 seconds the orange LED comes on for about 4 seconds and then turns off <---I've not seen any other posts mention this.
The phone will not boot still though - tried holding down power for 60 seconds, and even tried in conjunction with volume up and volume down.
The screen remains black, no vibration, no HTC logo .. nothing.
My wife has the same phone, so I put her battery in mine and it still will not boot.
My phone is NOT rooted or modified in any way (using stock VzW rom)
The screen is cracked but it's been that way for months and I've had an Otterbox on it ever since (go figure .. should have had one before it got broken). It's been working fine. It has not gotten wet today, or been sat on, or dropped or even looked at funny.
The phone is out of warranty and I do not have VzW accidental coverage.
Are there any more tricks to try, or should I go to the store tomorrow?
Thanks!
I am going to plug it into the computer and see if ADB will see it, but my assumption is no.
I'm thinking maybe the processor died... ???
I know if a PC processor dies then nothing happens when trying to boot .. no post beep or video.

Try charging the battery on your wifes phone then turning yours on and see if it works if the processors dead like you assume then well R.I.P Rezzy if you call verizon they will tell you to do a factory reset from the recovery maybe you could try that
