Boot loop or power button? - T-Mobile Samsung Galaxy S II SGH-T989

Ok here's the problem
My brother's GS2 is on stock gingerbread, just rooted. For a long time over 4 months it worked fine. Just randomly since 2 days if u turn it on it keeps buzzing. It might turn on go through the splash screen but halfway through it will buzz again. If i hold any buttons it might go into odin mode or cwm but just restart by itself after. Anyone have any suggestions how to fix this? I can't afford another phone.
Also if I put the battery in the phone buzzes and starts to boot itself without me pushing the power button. I tried taking the board out. Took some alcohol and cleaned up the power button and charging port. Let it dry for a few hours then plugged everything back together and its still doing the same thing. Power button seems like a tight solder so i dont want to mess with it unless I absolutely need to

"bump"
Please any help would be greatly appreciated. Thank You

Evo damaged (screen doesn't work), not sure what is wrong.

Someone tried to steal my phone while I was recording a video, when I got it back, the screen didn't turn on. The backlight works when I turn it on, when it boots in, the backlight turns off and the screen remains black and the buttons light up, pressing the power does nothing when its on (the buttons remain on).
Not sure if it can be fixed or if its just broken.
This happened to me a few times, just pull the battery, replace and reboot. If it boots into that screen off phase plug it into a power source, and if it still doesn't light up then leave it off for a few hours, could be an overheat. If all that fails then you may end up on the toilet giving Sprint a ring.

Could be a corrupted battery,you can try pulling the battery and plug the phone into the wall and try turning it on.
Hey,
Pull an Andy Sandburg and throw it on the ground! then take it to sprint and have TEP replace it lol
just kidding, yeah it sounds like a hardware issue of some sort, like they said try a different battery or see if pulling it and trying to boot makes a difference.
When booting hold volume down as well as the power button to see if you are able to boot into the bootloader.
If neither of those things work I would say its the screen or in internal component man and you will need to take it somewhere to get evaluated and fixed!
Good luck!
I hope I helped If I did please hit the thanks button!

I tried different batteries, and unfortunately it seems to do the same thing. I opened it up and I'm almost sure there was some sort of internal damage, but I have no idea what it was.
Its such a nice phone, I am gonna be so sad if it doesn't work. I'm putting it on the charger right now with a dead battery. I hope it works. If not, I have a very expensive HTC battery charger... :/
Its been broken for like a few months now, so I don't have much hope, but if it works then I'll be happy.
hey,
Yeah I have a broken htc and i use it to charge my batteries to, it works really well since you dont power it on but yeah,
I hope it works for you man. good luck

[Q] HOX wont charge nor boot after a drop

Hey there guys,
I was repairing an HTC One X for someone i know, (she dropped it and broke her glass) but since i got it (ofc) i tried to turn it on.
No succes. So hey, why not walk to the charger and plug it in? No charging light.
Opened up the phone and checked all the connectors. they were fine.
During an hour or two charging, i was googling, and some people reported that holding vol +&- and power button would revive it. no success.
I'm not replacing her glass untill i know this isnt a hardware problem
Please, share your knowledge
Greetings,
djpbx
UPDATE: Suddenly the hox's led started to blink, idk anymore what i tried and buttons and power combinations but lets leave it going. fingers crossed then.
UPDATE: No boot after the blinks (just faded away again), put another battery in it and boom, it booted. only nothing on-screen lol, lets replace that screen.

cell phone keeps vibrating will not turn on

hi. i got a tmobile samsung galaxy s2. I am out of my warranty. i had my phone for about six month thru a warranty exchange.
I was browsing espn.com, then out of no where the phone turned itself off and started to vibrate. I have tried to power it on, and it just vibrates. it turns on a quarter way then begins to vibrate. i left the battery out since the problem started waited the whole night to pass, still just beeps.
I googled how to put phone into discovery mode, but when I do the steps, it also powers the discovery mode quarter way then turns off and starts to vibrate. Is it a sticky power button. The power button presses normally,doesnt resist when i press it.

Sounds to me like a sticky or stuck power button. If you can take it apart...clean around the button that might help. There are a few guides in the Skyrocket forum on how to do it. Search for sticky power button or look at the stickies by Vincom. I have a T989 as well and used some of these methods and it worked. Good luck!

To be honest your probably going to have to the the button replaced I had same issue I tried everything to cleaning it and around it and even prying it away from the connector and nothing worked I had to send it into Samsung and they had to replace the motherboard thankfully it was still under warranty its worth a shot to call em n ask if yours is

I had the same issue, took it apart and tried cleaning to no avail. I called a local cell repair shop and as soon as I said I had an S2 and started to describe the issue, he stopped me and said it was a short in the switch, which had to be replaced, and gave me a quote. Seems to be something of a common issue.

How much was it for the shop to fix this?
I am looking at buying an S2 for $100 that is doing this shut off & vibrate.

I got something similar happening to a S2 I have. I was using it, it just shut down and won’t boot anymore. As soon as I plug it in it'll start vibrating indefinitely, pull the battery and re-insert it, and it'll keep on vibrating indefinitely. Sometimes I see the SAMSUNG logo but that as far as I can get. RECOVERY doesn’t work, ODIN doesn’t work, no button combination works... seems kind of dead to me.
You guys think it’s worth sending it to SAMSUNG and getting a quote to get it repaired?
EDIT: sometimes i can get into download mode for about 3 seconds then it blue screens and reboots. I can get as far as pressing the VOL+ up and then reboots...
So did anyone find a solution or was it a "short in the switch"?

SOLUTION !!! Hey i share your pain... i have an
S2 as well and have been facing the same
problem... my phone is rooted so at first i
thought the problem was due to an unstable
custom rom... anyway the REAL problem is
called a "STICKY POWER KEY". all you need is a
bright light, a can of CRC (the none conductive
type) and a Phillips head screw driver.. you need
to remove the back cover of your phone, remove
your battery and or charger , sim and sd card
then remove the six screws that is holding the
phone together. after that , carefully pry open the
phone and remove the circuit board that has the
power button and the volume Buttons.. this is a
little tricky because in order to get the circuit
board out you will need to detach some
connectors.. now you need to spray some CRC
on the power button using the fine tip straw that
comes with the CRC CAN .. then you just need
to press the power button until you get tired... i
use CRC intermittently while i press, be careful
not to get too much on the circuit board tho..
when you are done , put the phone back together
and let it sit for an hour then replace the battery
and turn on your phone voila ..... feel free to
inbox me if you require further assistance...

Phone died?

Hello everyone.
I have been using Tasks ROM for a while now. Last night my phone had a random reboot and other than that, no troubles.
Well about 20 minutes ago, my phone just turned off and will NOT come back on at all. I have done nothing different, cant get in to get a logcat or lastkmsg. It will not even boot up to the samsung screen.
It will vibrate when I plug it in or take out the battery and reput it in.
The only response I am getting is taking everything out (batter/sim/sd) and plugging it into my comp. The response is a Red light in the notification LED and a short vibrate, then nothing.
I get a Samsung logo if I just pull battery and reinsert.
Any help would be greatly appreciated.
Thanks
So you can't get into CWM or TWRP? And what Galaxy S3 Variant are you using?

Ii it possible you may have a bad battery? How new is it?(not that age of it matters) Also, do you have a case on the phone? Check to make sure the power button is not stuck. If you can get to boot logo, then its not dead-dead. If you've had your phone for awhile, double check the battery terminals are not oxidized. Unlikley, but worth checking and maybe check battery wih voltage meter if you have access to one. Then charge it overnight and check it again. One last thing to try is plug it in with the battery out and see if that does anything. Have you flashed anything lately? Modem? Scripts?

I have taken the battery out and plugged the phone straight into the computer and all that i get is a red light where the notification light is and then it disappears.
As for age, its a little over a year old.
I wasnt doing any flashing at the time, it just went kaput right after a phone call.
I had a mophie case on it, but not right now. I guess ill take it a part when i can and throw som alcohol on the battery button to see if it loosens it up. But other than that, I'm at a loss.
Not trying to pay $80 for a craigslister either.

Man, I don't know. Sounded like a charging issue at first, but looking I'm not so sure now. Anything stuck in your power slot? Maybe try leaving battery out overnight and see if it clears anything. If it starts to boot I would go right to recovery and try flashing something. I would be concernedabout going straight to download mode and using oOdin cause of it does during the flash that is really bad...
Can you get into download mode? Pull battery plug in USB and hold volume down and home buttons I think... when you plug USB in to computer does Odin recognize it at all?

I just started having the same issue. I have a an ATT S3 running the newest Hyperdrive. Mine wasnt doing a random reset, but it seemed like it has been turning itself off. Totally intermittent, i couldnt pinpoint the cause.
Then just today when i went to see if i had any messages and the phone was off again (i had about a 60-75% charge) I hit the power button a few times and now i am getting the symptoms described above.
When i try to go into TWRP, i get the blue text at the top left of the screen, sometimes i make it to the first hyperdrive screen, then it goes black.
When I go to download I can get to the hit up or down screen, i hit up to go into download, i get to the next screen then it goes black again.
I did leave the battery out for about 15minutes and no dice. I even tried to leave it on the charger thinking i lost all charge or something.
I am just a mere user, but i have always been able to tinker around enough not to bother the devs and get my way out of these situations, but I think i am stuck. Anyone have any ideas?
Thank you!

Maybe a stuck power button? Try cleaning it out a little. .. sounds like it's rebooting itself.

If the power button was stuck on, wouldn't the phone keep trying to restart? Or no?

I believe so, unless you pull the battery. In fact pull battery plug into usb and go into down load mode and see if it restarts. Or go into recovery without holding power button, and if you can then that means the power button is stuck on.

I have tried that as well. Whenever it goes into download mode the screen goes black after a couple of seconds. And it doesn't boot into recovery as well since it seems to go dead too quick.
I mainly just want to recover my pictures at this point. I am leaving the battery out of the phone for the day and see if that makes a difference this evening.
I am out of ideas, lol

Pretty sure the flex cable on you're power button is not working as intended, could be a short from a rain drop or just everyday wear and tear another issue could be that the battery is fried and can't hold a charge, but this seems unlikely given you're circumstance.
I always tell people to utilize pie controls to save you're everyday use from wearing out our precious hardware buttons, My power and home only get pressed to wake the device, everything else is pie control via LMT launcher
That happened to me a few months ago. I was at work when it happened. The phone would just continually restart, vibrate, restart, back and forth. I ended up taking the battery out so it wouldn't get drained. Had it out for about four hours. Once I got home, I put it back in and never had any more problems. It was just a random thing, so try keeping the battery out for a while.
I'll keep my fingers crossed. I took the phone apart last night to clean it out and it was pretty spotless. But It keeps shutting off after trying to boot after a few seconds. I just hope I can get to a point where I can get my pictures off of it now.

Hello all, as an update, I did nothing to my S3 over the weekend haping something magical could happen.
Today I went through all the normal steps again, and still a dead soldier. Now it wont ever SHow the Samsung logo however - just a short vibrate then nothing..
Still get a red light and a short vibrate when plugging into the comp without battery in though.
I have NOT taken it apart yet, but I will tonight most likely.
Thanks for all the suggestions and Ill keep this updated.

Hello again,
Some news, I am able to get it into download mode for about 1 second then the phone shuts off - just like the other person in this thread with the same issue.
I took the phone apart and used a Qtip with 91% isopropyl Alcohol to try and clean the power button (which looks surprisingly clean). Still the same thing happening.
I'm running out of ideas here, so please chime in if you have any.
Thanks

I was going to try the alcohol tonight, but I am afraid that I will have same results. I am going to try a new battery from another s3 tomorrow. I will post the results.

Final update (hopefully)
I got the qtip and scrubbed anything to do with the battery, pressed the power button, got more alcohol in by the button (not a lot) scrubbed some more terminals, and the battery terminals, etc. waited about ten minutes and put the battery in...
Low and behold, something worked and now the phone comes on.
I dont know which part of the scrubbing actually did it, but something worked.
All in all I have no idea what actually fixed it, but the point is that it works.
Thank you for who those that insisted that it was a power button issue - you were most likely right.
So here are my results as of today, and what I have tried to get to this point:
After my S3 died and wouldn't boot up into recovery i tried cleaning all the internals with alcohol. I cleaned thoroughly, and focused on the charging port, the power switch and battery terminals. The phone acted exactly the same.
I then tried putting it in a bowl of rice for about 24 hours. I was thinking that it might have been caused by some condensation. No success.
I was thinking since the power would turn on whenever i plugged the battery in, that maybe the switch was stuck. I took it apart again and tested the switch with a multi-meter. The switch seemed fine. It was responding when i pushed it, so i figured that wasn't the problem.
I kept reading that apparently this is an issue with the mother board. I tried the broken PS3 method of heating up the motherboard with a heat gun in hopes to re-seat something that may be loose. This did not work either. After this, I figured i was SOL since I was out of ideas and out of warranty (which didn't really matter anyway since I am running Hyperdrive).
Earlier today I figured the best tool in your toolbox sometimes is a hammer. I started tapping the phone on the side of my table, especially around the power button, while trying to turn it on. It didn't seem like it was doing anything either. I then plugged the phone into the charger since i thought the battery was totally dead.
A few minutes after i walked away from the phone, I came back into room and the red charging light was on. I tried turning it on, and holy cow it works...wtf...
I have no idea what made this work. It could be a complete coincidence. But, this phone has not worked since last Saturday. I just kept messing with it and may have just gotten lucky. I don't think banging your phone will fix this, but if truly was a hardware issue, maybe something in the phones mother board is becoming loose from the extreme heat they endure at times. I know my S3 has gotten pretty hot when I use it to navigate and leave it in the case.
I don't know if any of this will help anyone, but this is my experience so far of my S3 having what I think is the sudden death failure. I will followup with any updates if it decides to act up again.

[Q] Desire wont start up. The screen just keeps flashing.

So i went out on a night out and my battery went flat whilst i was out. I come to start it after charging it up and it just keeps popping up with the start up screen for a split second and then going off. It keeps doing this until i unplug the charger or take the battery out. I managed to get into the reboot screen and tried starting it from there to no avail. The battery is only a couple of months old so that should be good.
I took it to a phone repair shop and they said the board was gone and that there was nothing that could be done with it. Is this the case?
I don't generally turn it off just keep charging when it gets below 20% battery life. I did however install solitaire since i last powered it down if this might have any influence on the situation.
Check if you can get into the bootloader. Hold volume down and power.

I have tried this but although it comes up with the bootloader screen it flashes off gain as with the boot up screen. It does not give you time to do anything in the bootloader.

Are you sure the battery isnt completely dead? Did you drop the phone or do anything that may have caused this, or did it just suddenly occur?

No i have charged and recharged it until the green light comes on. The chap at the shop tried another battery also and this had no effect on it.
I dont recall dropping it. It is in a substantial wallet holder so i would think that would take the brunt of the blow even if i had. But it worked fine all night until it powered down then it just started to play up.
Right while messing a bit further it seems to me that the on off button is constantly activating. If i just hold the return button it comes up with the reboot screen and allows me to choose the various options. If i hold the volume button the fastboot screen appears but disappears just as quickly. All of this happens with out me touching the on off button so it looks like it is constantly trying to start up. The button does not have any visible signs of damage. Is this a normal failure point for these phones?
If it charges completely while it's off, then the board should be fine. You can check the percentage in your recovery mode if you can get there.
If the board is fine, it either means that the button is stuck or you have some gunk short circuit in the button.
If it's gunk, you might get away with some rubbing alcohol, If it's in a spray can, even better. If it stuck, it should be opened and see what's keeping it pressed.
I hope this helps.
