This exact thing happened to me.

I couldn't ODIN or went into recovery because the phone wouldn't stay on long enough.

It would turn on for a few seconds and died and would constantly vibrate.

I tried JIG to force into download mode. Didn't work.

I tried JTAG service. Didn't work.

I was lucky enough that the phone was still under warranty so I had it replaced. But I think your phone is as good as gone.

You can always try JTAG (the only service that MIGHT bring your phone back to life) and hope that you're luckier than I was.
[T-Mobile Samsung Galaxy S II SGH-T989] Radsolutionz:
yeah i think its beyond fixing, as far as what im capable of. I knew the answer just wanted to hear it else where.... i contacted mobiletechvideos.com for a jtag service lets see if they can fix it. other than that.... u know anyone who would buy it? for 100 bucks?
[T-Mobile Samsung Galaxy S II SGH-T989] belly1026:
I suggest that you send it for JTAG service anyway. If they can't fix it, they'll refund your money less shipping charge so you're only out a few bucks.

If they could fix it, then you obviously could sell the phone for a little bit more. Considering that you're already willing to cut your losses anyway, might as well give it another week or so. At least this way you know that you've tried absolutely EVERYTHING and know for sure that the phone is actually beyond fixing.

Or, you can try contacting this guy.

He's looking to buy a T989 motherboard. I'm assuming a "working" motherboard, but hey... you never know, right?

Good luck!!!! :fingers-crossed:
[T-Mobile Samsung Galaxy S II SGH-T989] Radsolutionz:
is there anyone u recommend for jtag?

Could you get in recovery at all?
[T-Mobile Samsung Galaxy S II SGH-T989] belly1026:
Everybody on here raves about MobileTechVideos and how this guy can fix anything

here's the link

Notice that they charge $50 on their website.

But if you were to go through eBay, they only charge $35!! A saving of $15 :-)

Here's the link

I didn't read the whole description, but you can read the "refund" part in case they can't fix your phone.

I personally didn't use MobileTechVideos because when I was looking to have my phone fixed, they took a while to respond to my questions (like a day or two).

So I decided to use this guy's service that I also found on ebay: click me

Although he wasn't able to fix my phone, communication was flowing nicely. He'd respond to my e-mail a few times a day. And when he refunded my money, he didn't charge "diagnosis fee" or anything like that.

But then again, since he wasn't able to fix mine, you might want to try MobileTech and see if they can perform magic with your phone.

SO IT IS JUST A DEFECTIVE POWER BUTTON, i trust this guy because hes came through in the past... soo its 35 bucks, im just gonna send it out, shes got a loaner phone for now, lol she hates it... i just told her the good news, so she wont be wasting the 350 getting her self a new phone, thank god... n e way thank you all for your help. this is what the xda community is all about.
[T-Mobile Samsung Galaxy S II SGH-T989] belly1026:
Well, I'm glad to know that he could get it fixed.

Better than selling it for $100, right? :good:

And I think he's based in College Station, so it won't take the phone too long in transit to him and back to you!

I wish that he had communicated like this with me. I would have had him fix my phone as well.

Although I had a replacement phone from T-Mobile, there were some data in in the internal sd card that I would have liked to save from the old phone. Oh well.

And... you're welcome!!! :D
[T-Mobile Samsung Galaxy S II SGH-T989] singlebyte:
MobileTech is awesome.....Used them 3 times now.......

But one more suggestion....

Try to fully charge battery with another charging source. I have seen batteries get so low they will not come out of this power cycle. Not sure if it is a hardware or software issue but I have had it happen to me. It just keeps trying to boot but doesn't have the juice to complete.

Other than that....MobileTech! (They are great!)

---------- Post added at 10:16 PM ---------- Previous post was at 10:13 PM ----------

One more idea.....

Make sure you haven't grabbed a wrong charger or cord. I one time grab the kids Samsung charger to charge my T989. Problem was it was not pushing enough juice for our phone model. It FIT but DIDN'T work!
[T-Mobile Samsung Galaxy S II SGH-T989] Radsolutionz:
yea, personally i know the phone is working... and ill only go to someone else if i absolutely tried everything i can think of, i mean i fix and root phone for other people all the time... so when i cant figure something out.... its kinda a big deal. i would have never guessed it was a faulty power button, i was going to open it my self. but id rather just send it out and get it back in a week
[T-Mobile Samsung Galaxy S II SGH-T989] Radsolutionz:
Shipped the phone off this morning should know by next week wuts up.... will keep u guys updated. Its a good thing my galaxy s 3 is insured and under warranty!!! Lol I paid 500 bucks for this phone the day it came out!

[T-Mobile Samsung Galaxy S II SGH-T989] rymanh:
I had a feeling it was a hardware issue... The whole vibrating thing didn't make sense.. Usually if it's bricked it doesn't do anything at all

[T-Mobile Samsung Galaxy S II SGH-T989] rymanh:
:cool:
[T-Mobile Samsung Galaxy S II SGH-T989] connexion2005:
Thanks for the referrals guys. Remember we repair over 4,000 devices and counting annually so we have almost "seen it all". I'll be making a YouTube promotional for my Samsung power button services soon to help raise awareness on this subject. To my knowledge no other shop offers the button repair service on this unit. This is also most likely because they aren't aware of how to diagnose the issue as many wouldn't believe it would be power button related. I verified this when I first found a T989 with a bad power button by monitoring the current draw on a digital power supply. It would pull current with zero button presses. After a new button, it was good to go and the T989 power button service from MobileTechVideos was born... ;)

If you have the same issue as stated in this thread then you shouldn't need to brick your device to get a warranty replacement..

Btw intentionally bricking your device to get a warranty replacement is dishonest and probably illegal and it won't be discussed on xda
[T-Mobile Samsung Galaxy S II SGH-T989] EnigmaticGeek:
If you are still getting a boot animation, then you aren't truly bricked yet. There might still be hope in recovering your device. Have you tried to odin back to stock?

sent from my T989 full of CM awesomeness and a touch of Venom from the Darkside!!
[T-Mobile Samsung Galaxy S II SGH-T989] jioooz:
I did, there is not way it is going into odin or download mode. But on the bright side of things, I took apart the phone, messed with the power button and got it to work! apparently it is a part defect, so now I just have to restore back to stock and warranty will cover. Thanks
[T-Mobile Samsung Galaxy S II SGH-T989] frankaloni:
I have this same problem that is apparently related to the power button (the sudden turning off, the vibrating at 1–2 second intervals, the dark screen), but on my phone the camera flash is also going off. Does that mean anything extra special to anyone?

As it happens, it flashes at the same interval as the vibration. Except sometimes it doesn't seem to feel like flashing; the vibration is consistent, but occasionally the flashing won't start at the same time as the vibration, though eventually it will start flashing too. A few weeks before the power-button / vibration issue appeared, on one occasion the phone turned off suddenly at the same moment the flash went off when I was taking a picture.

At this point I can't even get it to reboot by fiddling with the power button and I have the battery out, getting ready presumably to send it off for repairs.

Everything's stock on the phone.
[T-Mobile Samsung Galaxy S II SGH-T989] jioooz:
This may sound silly, but try hitting the corner of the phone (where the button is) against a semi hard surface. Make sure to turn it off, keep the case on or wrap it in a towel or something similar. The main problem seems to be the inner part of the button is getting stuck so smacking it around actually frees it up. Happened to me a few times now. Just be careful not to damage your phone.
[T-Mobile Samsung Galaxy S II SGH-T989] burntuakrisp:
Try this

I had this problem and learned from reading all the posts in this thread that it is a power button issue. I fixed mine by taking a small screwdriver and worked it around the power button gently, and the vibration issue stopped.
[T-Mobile Samsung Galaxy S II SGH-T989] jessask214:
hey im having the same problem

This is exactly whats going on with my s2.

Im in Dallas as well. Is there anywhere u know

I can personally go to to fix it. Instead of sending it off?
[T-Mobile Samsung Galaxy S II SGH-T989] machaira9:
screwdriver solution worked for me

that worked for me, too. took the smallest flat-head screwdriver i had (from one of those sets of tiny/thin screwdrivers) and gently worked it around the two longer edges of the power button. didn't really feel like i did anything (other than introduce a tiny, cosmetic notch in the edge of the power button slot), but when i tried to turn the phone back on, it worked!

it's been on for 20 mins or so. hopefully the issue won't come back, but at least i can send it in for a replacement button if absolutely needed. i'm most thankful that i have another chance to backup all my data (photos and what-not).

thanks, everyone! :victory:

Out of curiosity, is anyone else who's having this issue using the D30 Impact Protection cover?

I noticed, with mine, that the power button (while using the cover) has always been difficult to press in (whereas the actual power button, without the cover on, is super easy to press). I wonder if there's a correlation between the stuck button issue and the cover. *shrug* Just curious. :)
[T-Mobile Samsung Galaxy S II SGH-T989] Quadratomic:
I'm using the D30 Impact Protection cover as well.

I had the same problem; for a week or two prior to the continuous vibrating/not booting, my flash would fire off in rapid succession, and finally today it ceased to boot at all. I took jioooz's suggestion (thanks!) and tried it out and my phone is running just fine now.
[T-Mobile Samsung Galaxy S II SGH-T989] EternalSoil:
I also use this cover. Anyone having the power button issue and NOT use this cover?
[T-Mobile Samsung Galaxy S II SGH-T989] frankaloni:
Yes.
[T-Mobile Samsung Galaxy S II SGH-T989] EternalSoil:
Okay, just wanted to make sure.
[T-Mobile Samsung Galaxy S II SGH-T989] frankaloni:
Although, now I'm not so sure. I mean, I'm still not using that cover, but—any chance these same symptoms (rebooting/vibrating, plus the camera flash going off) could be caused by shorts on the motherboard?

(I took the phone into the shop to get the power button replaced; at first they said it looked more like a software issue that could be fixed by flashing it if they could get it to stop rebooting long enough to go into download mode, but then they called me up and talked about shorts on the motherboard instead. The thing is, following some of the power-button-related advice given above, such as tapping the phone against a semi-hard surface in a way that would loosen the button up a little bit, seems to have actually helped, because doing that lengthened the rebooting cycle a little bit too—just not enough to let it get the whole way booted up.)
[T-Mobile Samsung Galaxy S II SGH-T989] drLouie:
Mine just started today and yes I've been using the D30 cover since day 1. Wonder if the case hastens the problem occuring.

[T-Mobile Samsung Galaxy S II SGH-T989] Snooplongylong:
Had to fix my sister's phone. Power button was broken and she was using the D30 impact case as well. Common issue with this phone and I guess this case hastens it. I used the MobileTechVideos site recommended earlier in the thread to fix the issue.

They fixed it for $35. Altogether, it took about a week to fix. Great service. And thanks for everyone on XDA for diagnosing the problem!
[T-Mobile Samsung Galaxy S II SGH-T989] Kidovzky:

[T-Mobile Samsung Galaxy S II SGH-T989] railmeat:
Thanks for this.

Found one on ebay that was having this issue. Got it very cheap :)

The screwdriver trick fixed the issue instantly, both power off/vibrate issue, and call sound.
[T-Mobile Samsung Galaxy S II SGH-T989] railmeat:
So, the screwdriver thing was only a temporary fix (if at all). I gave up and sent it to MobileTechVideos via ebay. $35 plus shipping one way. Problem Solved.
[T-Mobile Samsung Galaxy S II SGH-T989] paypalbid:
Problem solved. I wrapped the phone in a towel and hit it on the granite counter where the top corner of the phone near the power button. Phone works like a champ again. Thanks for the tip guys.

PS: Some phone refurbished guy told me the phone was done because he believes the mother board is damage. I'm glad i did the research and turned out to be a sticky power button.
[T-Mobile Samsung Galaxy S II SGH-T989] awoolf:
This is a old thread, but lots of people are being linked to it. So, here's some good, up-to-date info on this problem:

This is almost certainly caused by a bad/stuck power (on/off) switch. It's a very common problem on all the US-carrier Galaxy SII phones. (I think the international "i9100" model uses a different type of switch.) You can simulate the issue on a good T989 by holding down the power button when you turn it on - it will reboot and then vibrate every few seconds with a blank screen, until you release the power button.

Some people have had success poking/pulling/cleaning/washing the switch, but replacing it is the only long-term reliable fix.

If you don't have insurance coverage and are out of warranty, you can replace the switch yourself. Several eBay sellers offer replacement power switches for the SGH-T989 Galaxy S2. (about ten bucks)

Or, if you don't have mad soldering skills, a few companies offer mail-in repair service:

[T-Mobile Samsung Galaxy S II SGH-T989] nelsonmunoz:
works for nexus 5 too!

Thank you! I'm soo glad to have read through this old thread, it did the same with my 32gb black nexus 5 and it fixed it. After leaving it charging overnight, it wasn't powering on or responding to plugging/unplugging or charging or button presses or combinations, only did the very slightest repetitive vibrations (as in easly mistaken for my own pulse both in lightness and frequency). So after reading this i put on a cover, wrapped it in a towel and smacked it good agaisnt a hard surface in the corner right above the power button with it facing down, so it would dislodge itself. Sure enough, it worked!. The phone is no longer "bricked" and working perfectly.

I suspect the cause of it might've been a google cardboard headset i'd been trying on wich must have pressed against the power button too hard.

[Android Development on Bada] Rebellos:
Now we're talking. I think...

You'd have to write your own bootloader (or modify existing one anyway) - wiping Bada is dangerous, because if something go wrong you are without Bada and Android. You should look for the safest way of modifying existing bootloader, or, even better - find some security hole where you can inject your code, without modifying bootloader, as we did with S8500/S8530, we're convincing bootloader there's Samsung's FOTA module to execute, but it's in fact our own code. I'm sorry, but I can't help you in that. Too many projects atm taking my time.

Long, long time ago I checked some bootloader from S5330 (boot2.img). It did have the same Fota_check sequence as S85x0. Most probably the same would be for S7230 so it's the matter of analyzing the bootloader to get the right addresses to be able to boot something else than Bada. Then, it's completely different story how to get the right drivers working and that will not be kindergarten as well.
