samsung s2 skyrocket bootloop plz help!!!! - AT&T Samsung Galaxy S II SGH-I777

Hi,
So my SGS2 Skyrocket is stuck in a boot loop. I've have the Sky Icecream Sandwich ROM installed for a few months now, and haven't changed anything recently.
What is happening is my phone with vibrate every 2-3 seconds with a blank screen. When I take out the battery/power source, and put it back in, the phone shows the Samsung splash (not the Android splash) for a few seconds, then goes blank and does the vibrating again.
I've tried plugging it into the computer, but the power it gets from USB turns it on and into the boot loop, so I can't get it into any kind of recovery mode. I also tried the Vol+Home+Power key combo, with nothing.
Any idea what could cause this/what the course of action should be? Thanks!

The Galaxy S2 and the Galaxy S2 Skyrocket are two completely different phones. This is the forum for the Galaxy S2. Go ask this question in the forum for the Skyrocket.

Haven't seen one of the slow rockets in here in a while. Good to know they're still around

Vibrant Wont stay on

ok so my (edit) *Vibrant is not booting up...
I press the power button, the vibrant turns on, logo pops up, boot animation, Tmobile animation and galaxy s animation plus sound all happened, The phone gets to the lock screen and within 3 seconds just shuts down.
Anyone know what could be wrong.
Phone is stock, neither romed or rooted. is this a battery issue, hardware or software
Does it boot up when you have it charging? And which phone is it, the Vibrant or the Captivate? Those are 2 different phones.

sorry simple mistake, it is a tmobile vibrant...
it boots up when plugged in and when not plugged in... gets to the lock screen and it just waits and then shuts down completely.

If you can boot into stock recovery/download mode, just do a factory reset or flash the stock rom using odin

Maybe you have a defective bootloader or phone. If it's still under warranty, just bring it back to T-Mobile and exchange it.
was trying to fix a vibrant for a friend of mine with a very similar problem
after many hours of work w/ odin & attempting to flash different things.. i concluded that it was hardware related bc i made it all the way to stock but it would just shut down randomly
does it give any sort of message when it shuts off? or just goes black?
have you dropped it a lot?

im starting to think its hardware related as well. at time when i boot into stock recovery the battery logo just shows up, the android man with the the exclamation point. idk if up to a certain level of currect is drained the battery shorts out. how can i possibly test the battery??
There is no message or anything... as soon as it boots up to the lock screen it just goes black.
i just acquired this phone. I have a HTC Glacier that i use for my everyday. this used to be my friends old phone and it started doing this, he just got another one and gave me this said if i could fix it i could have it to mess around with. as far as i know it hasnt experienced much rough and tough life. on the outside it looks almost brand new.
So I bought a brand new battery and the vibrant won't even charge the new battery...

sorry to revive this but did you try cleaning the battery contacts?
You probably moved on with life lol

[Q] Galaxy Vibrant - 2 Problems

Product: Samsung Galaxy S Vibrant i9000m
Problem 1:
Connect usb into phone from laptop - both connected
Battery appears for second and continues loops
-=-Unplug
Problem 2:
Power on phone, stays on Vibrant Logo
I try to get into recovery and it just loops the Samsung Galaxy S and Vibrant logo.
Looking for solution to fix this, as it wont connect to my laptop - cause it loops and since it does that, I cannot use odin.
Have you recently dropped it? Ive seen phones get dropped or knocked around and a cable/ribbon comes a little loose on the inside that will cause that. I usually take apart and re-seat the cables/ribbons. By the way, are you running a ROM?
Sorry for late reply
I managed to fix it in the afternoon, I placed the stock of the wrong provider on the phone and it messed up, so I found Sasktel i9000m stock firmware and installed that without problem. Thought it bricked on me, but got it fixed

HELP! Samsung galaxy s2 sgh-t989 stuck in the ultimate boot loop.

Ok, so heres the deal. The s2 is my sisters phone, and she comes home and told me the phone wont turn on, that its stuck on the boot screen and it just keeps turning off and doing it again. So I started looking into it (Im an iPhone user, so I'm not too familiar with android devices. BUT I do know a bit about computers, cell phones and just technology in general). I ended up finding out that its stuck in a soft brick. So I started youtubing how to fix it. Found a great method using Odin3 and Samsung Kies. AND IT WORKED. I turned the phone back on, got past the lock screen and everything was all good.
After about 30 seconds, THE PHONE BRICKED AGAIN:crying:. And it went right back into the boot loop, I cant get it into download mode because it just keeps restarting after a couple of seconds. With that happening, I cant get the computer to recognize it so I can do a recovery fix with Samsung Kies. I legit cannot find any solution to it.
The thing that baffles me and is causing me a huge headache is the fact that THE PHONE IS NOT ROOTED. nothing has been done to it, its completely stock. So if there is no solution to it, can somebody at least tell me what might have been able to cause this?
Thanks to all,
Dariel
Well, you're in the wrong forum for the SGH-T989. That's probably your issue.

[Q] Galaxy S2 won’t start if after upgrading to Jelly Bean

I recently upgraded my Galaxy S2 from 4.0.3 to 4.1.2, upgrade went well and everything seemed to work fine till my battery discharged.
I charged the battery and tried to start the device, I can see the initial galaxy screen (the one with the yellow rectangular) after which the screen goes “black” and the device doesn't proceed any further.
Tried to turn off and then on the device, and the same behavior.
The device will not start if for some reason it gets turned off but the device gets heated significantly even though it seem to be turned off, I can turn it on only if I get into recovery mode and restore the 4.1.2 rom from my backup
Any suggestions?
Use common sense just use Odin lol

[Q] possible brick?

Hey guys and gals, I think my note 2 is bricked. I am on stock rom, dont know specific builds, probably whatever is the latest update. I was using the phone friday afternoon and all of a sudden it just shut off. I tried to get it to turn back on, but it would only go to the Samsung galaxy note 2 bootup screen, then do the sounds to boot up. Then it would reboot. I did a battery pull, and it will not even make the sounds now (still get the bootup logo) then shuts off. I have searched some on the forums and I can get it into download mode and i can get to the screen where i can reboot/factory reset/ update (i have the red triangle w/ black exclamation mark). I have to hold the buttons down first and then install the battery to do either though. I have played with roms some when i had a galaxy nexus, but am a little rusty on it. I have not tried to install any roms on this phone though. Anyone know what might have went wrong/what i need to do to fix? I did a factory reset to no avail. Also, like i said, i have done some flashing if thats what i have to do, but really good directions would be great. Thanks.
