shuts down, and showing no signal - Galaxy S II Q&A, Help & Troubleshooting

Hello!
I have this problem with my s2.. I was browsing for my joy when suddenly the screen flashed couple times and my phone suddenly shut down (when battery was about 70%).
I already had this kind of problem but last time it was the battery (it swelled) but i replaced the battery and for a month or so everything was fine.
now with no warning it happened again!
I checked the battery its fine...
now when I boot my phone up it stays up for a minute or so and freeze or shutting down..
and also the signal icon shows that there's no signal!!
when its off and plugged to the charger its all fine looks like charging...
sometimes when it shows the samsung logo on boot I can see the the lights on the back button and menu button flickering and then shutting down.
I didnt download anything new in the past week..
did anyone here had this kind of problem? how can I fix it?
PLEASE help me I was at a job interview and they should call me today !! T_______T

ROM?Kernel?Did you try Factory reset or flashing stock ROM?

Are you using a genuine s2 battery or it's just a generic one?
It's a generic, isn't it?
Sent from the little guy

I did hard reset, now running Samsung's original ROM and stock kernel..
the battery is original..
somehow everything is now fine.. but I don't think that this is a normal problem.. it really freaked me out today.. I wanna know if any one knows what its all about and how to prevent it from happening.. thank you very much

TMobile PDA Phone keeps restarting and wont charge

It was unlocked and working perfect until the battery went completely dead and wasnt charged back up for a week. After pluging in the charger I was unable to do a complete charge as the pda keeps starting up. It runs for about a minute or two then restarts and boots back up, the cycle continues with no end. I got to work for about 10 ten minutes, the phone worked, the charger was active in the battery option menu, but then it started all over again. I've reflashed and changed roms. The amber charge light does appear. Also hard reset doesnt work. Please help, bought the phone used but only got to enjoy it for a day.!
It maybe the battery is banjaxed, I have seen similar behaviour with an ipaq and a defunct battery.
if not its board memory
if im right yourin big trouble u have to replace the whole main boards .. i hope im wrong it juist bthe battery.
good luck bro

Dropped my Ray now wont boot past the Kernel screen?

Seems like a power issue almost.
The kernel screen will show, and then it shuts off. Sometimes it makes it to the bootloader screen if i have the USB cable in, then shuts off.
Guess its like it has been the whole time i had it buggy
Anyone wanna buy a half dead ray?
Have you tried flashing ftf files, another kernel, or something?
Nahh. Tired of messing with it. $100
It probably could be a hardware issue. Any ftf or kernel flashes can't help hardware problems.

Possible fix...
I had the same problem on my Ray, but i don't know what happened to it, all of sudden starts to bootloop... Sony logo, stands for a while and then reboot... tried flashing everything, but no luck... everything i did ened with bootloop... Now i'm a happy ray user again. This is what i did... Turn on the phone and left it boot-looping until it drained the battery, until completely dead (red blinking when try to turn on), then i connected it to a charger and suddenly it started working again!! but when i turned it off, it couldn't boot again... So i did the same thing, left the battery drain, but this time with SIM and microSD inside, and when i connected the charger, but this time it didn't boot... That'
s it, the phone stopped booting again so i left it on the charger bootlooping all night, and in the morning i disconnected it and left the battery drain, AGAIN... the time when i got home from work, the battery was drained, i connected the charger and it started again! I used the phone for a few days without powering off/reboot, and now it's all fine, it boots normally, i use PACMAN rom and it's wonderfull... Hope this helps...
What you did was exercised the battery !!!
This happens due to battery problem !!!
But in his case , he may need to try out a new or working battery !!!

tried a battery, same effect. Going on ebay this week.

Galaxy Note i717 Shuts off

Hi I have a Note i717 with a custom rom and when I installed it ,I noticed my battery was draining quickly and sometimes it'll shut off at 100% and the battery had swollen up..I got a new one then the phone was working fine but the battery was still draining too fast.So when the phone gets to the splash screen it shuts off and restart.It does it over and over. I've tried different ROMs and it still does it.. I thought it was the battery again,I order a new one and it still does it. I've done the flicking of the power button,didn't work.Took it apart it and cleaned around the power button too.Some of the ROMs will make it to the home screen then it'll shut off after about 20 seconds.Some ROMs doesn't make it that far.It stays on only in recovery mode and download .Any advice?Thanks in advance.
Broken power button
This happened to me. I went to a repair shop and they fixed it for 10 dollars. I suggest that you do that also.

Possibly bricked phone.. Out of nowhere? Not even flashing

Been running the GPE ROM flawlessly since I flashed on the 12th... Until today. Don't know if this is ROM related but maybe you guys can help.
Out of nowhere, my phone kept shutting off. Couldn't use it for more than a minute after booting before it would turn off completely. Battery was charged so I was kind of like 'wtf'. Then all of a sudden it wouldn't even get to the swirling colors boot screen. It would shut off halfway though the Samsung Custom logo. ****.
Tried plugging it in and pulling the battery multiple times. I can't even boot to recovery! The blue text shows in the upper left but then it will go off again. It's plugged in now but not showing the battery charging screen.
I can only get it to turn on for about a second. Am I ****ed? Is this thing bricked? Super random because I changed NOTHING this morning and it was fine yesterday.

It could be a power button failure, it's actually quite common on the S4.

Phone usually doesn't turn on

Hey guys!
So i have this unusual problem with my phone. The phone won't turn on, but when i plug it in the charger it shows the battery icon with the little "loading" circle in it. It does that constantly when plugged in, icon is on the screen for a few seconds then the screen is all black, it goes like that untill I unplug it.
I thought that the phone was broken, but today while it was plugged in i saw the real charging animation and it said that the phone had 50% of battery so I quickley pressd the power button and it turned on normally. After that i turned the phone off and back on again, everything worked perfectly. So i tried turning it off again and pulling the battery out. Now it wont start again.
The firs time it happend I was using the phone and it freezed, so i pulled the battery out and then it happend.
The phone is running latest version of cm11 donwloaded from cm website.
I hope that somebody knows the answer to my problem.
Thanks in advance!

The battery is new
I'm might know what happening with your phone, and i don't know the final solution either, but you can use your phine with a little bit of effort, just plug your phone to charge and open download mode (press power key, home key , vol down key simultaneously)
And let be in that position for 5-10 min and then press cancel. Then it will show your device name for real long...... wright there for 5-10 min again and it will be working again, don't let it go off again or do same procedure if it goes off, you may have problem with your sensor's, wanna stable solution? Go to your service provider
