Strange Reboot Occurrence - T-Mobile Samsung Galaxy S II SGH-T989

Right now I'm on Darkside Evolution V8. I've been on it forever. Today, my phone RR'ed and then the screen stayed black and kept vibrating. I tried pressing the power button which starts the reboot process, but it hangs then returns to the black screen/vibrating. It finally rebooted to my home screen once, but whenever I hit my power button, it goes back into this reboot process. I tried going into CWM a few times, but it continued the reboot process even then. Can anyone explain what is happening with my phone, and how to alleviate this problem? Thank you in advance.

Your power button needs to be replaced. It's all over the threads here.

[Q] HELP! Rooted Mytouch Slide will not boot!

Okay, so for the past couple of days I have been having problems and I was wondering if anyone can help. I rooted my phone with Cyanoginger and it had been working fine for the last few months. I tried to turn my phone on yesterday and it simply vibrated and no screen came on. I decided to charge it and try again today. I turned it on and the screen got stuck on the mytouch logo. For the next times i tried to reboot it, this happened again, before it stopped showing anything on the screen all together. I tried to access the boot menu by pressing volume down then power with no result. Not even a vibrate from the phone. I was wondering if there is anything I can do to fix the phone, or if I should just give up on it.
Thanks a lot, Kevin.
Try pressing back+power to reach the bootloader, then from there get into recovery menu and load clockwork mod recovery.
Then flash cyanoginger again without wiping and then just wipe cache and dalvick-cache
Should boot up after 5-15 min
But did you flash a radio or spl/hboot or try s-off but it failed?
back+power didn't work. and for the last thing you said i have no clue what you are trying to say, so if you could please explain it a little better I might understand. thanks, Kevin.
lol that's because its not back+power
LMAO
Do this..
Turn your phone on by pressing the following:
Power+Volume DOWN+Camera button.
You will enter a screen, now select recovery by using the VOLUME and POWER keys and enjoy.

[Q] Phone possibly hard bricked, need help

So I'm running CM 10.2 android version 4.3 and I started to notice that when I pressed the power button, it brought up the reboot menu instead putting my screen to sleep so I downloaded the newest nightly and figured it was probably just a bug and went to flash the latest nightly. Upon reboot, my phone got in an infinite bootloop so I pulled the battery, let it sit for a minute and then held the power, volume up and menu button to enter recovery. I got the blue words in corner that you will normally see when booting into recovery, then saw the S3 screen that you'll see right before entering recovery, however, my phone started rebooting again constantly vibrating etc. So then I decided to try and get into download and flash back to stock with Odin. So I entered download mode, pressed volume up on the confirm screen and then it entered download mode and then immediately rebooted and wouldn't stop. Is my phone bricked? I'm wondering if the power button is broken since when in download mode, it reboots which normally occurs when you hold the power button in download mode. Sorry for the long description but just wanted you guys to know what I've done so far and am experiencing. Any help is appreciated. I've been rooting phones from all manufacturers for years now and I'm out of ideas at this point. Thanks!
Definition of a bricked phone: A completely unresponsive device which doesn't turn on at all. Doesn't vibrate upon start up and doesn't have any signs of life.
You most likely have a jammed power button as that has been the issue with the GS3. Not a brick.
Clearly not bricked as the first reply explained. And for the love of god, please use some white space (paragraphs) next time.
If you think that a button is jammed, see if you can physically unjam it without causing damage. If you believe that the flash may be messed up, the mskip's Samsung Toolkit may be able to reflash a known good ROM even with a stuck button. And look into some of the button remapping apps like the aptly titled Fix Broken Power Button app.
Good luck.

r800i LUPUS Softbrick

I've dug around trying to find a similar problem here and on google, so my apologies if this has already been addressed.
The problem originally began when the game pad stopped being responsive (or at times took multiple presses to get a response) and after no luck troubleshooting it, I tried to reset from clockwork recovery.
Ever since my phone no longer boots. It just sits on the LUPUS wolf logo (I do not recall exactly which rom I am running, but I hope this helps) and at first I thought it was your normal "this can take a bit" first boot, but I've let it eat the whole battery and it never gets anywhere. I've tried to prompt the phone to boot into both custom recovery and d/l mode and neither get me anywhere. Any suggestions?

IMHO, it looks like faulty slider flex cable (exact same situation i had, but i was able to enter recovery after 2 minutes of logo on screen)
Try to power on phone with slider open.
If you can enter in recovery mode with "volume -" (if it light blue led or vibrate) and see is d-pad is working.
Sorry for the delayed reply. The notification went into my spam folder :/
Alright, I followed your steps in two ways. I opened the slider and held both the power and the volume down till I got the buzz buzz and the LED blinked green once and continued to hold volume down till I got the LUPUS logo. No luck. I did mostly the same thing the second time but I held the volume down for 3 minutes with the same result. I still have yet to make it back into recovery.

To be able to enter recovery, it is not "holding volume-" while powering on phone or keeping it pressed.
Press power button (and it should vibrate), and release it.
When blue led is on press and release vol- button many times untill you enter recovery (don't keep it pressed all time)
Ah, you are absolutely right. I've never entered recovery like that on another Android before. I loaded up the "near perfect" rom and my game pad seems to be working for now, so it appears I am back in business.
How problematic is it if my slider flex cable is going bad? Will it permanently fail eventually?

HELP! I bricked my RK3188 Pumpkin..

While at the Android logo, did you push the reset button and waited for the system to correct itself? This will
happen when you load a fuse-prom the first time.
I have tried both the "RST" button push at the Android logo, and the smaller button that is not labelled. How long do you think it should take? Neither button seems to return the HU to normal, it just sits there at boot logo.
The recovery mode no longer works either, so it appears I am totally stuck!
Thank you for your help so far. Will go and try it again.
OK. Just tried a quick push of the reset button and it did nothing. Retried with a long push and it turned off the screen but nothing else happened. A push of the "RST" button just cycles the unit and it sits at the boot logo again.
Press reset button and power button together
After about 5 secs release reset button, but keep pressing power button
When booting screen appears release power button.
It boots into recovery.

Marius, thanks for the reply. My unit has no hard buttons, so this method won't work for me. I already got the unit into recovery mode ot apply the ROM, but after the unit rebooted the recovery screen is no longer working, it is just black with a few vertical bars displayed top left...
It is truly annoying.

I tried everything but nothing even logo you see
My unit is on its way back to Amazon. Nothing worked at all and I tried every recovery method on here.

Boot loop and random reboots after TWRP install/stock rom flash

Hi all, my Tab S 10.5 (T800) was running stock MM with no root. I tried using the Adoptive storage enabler patch from this site. After installing the TWRP using Odin and flashing the adoptable storage patch, I am stuck in that stupid reboot loop. I did selected "Allow modification to system partition..." in TWRP. I managed to apply the batch and after a number of attempts boot successfully, changed to internal storage etc but still getting random reboots all the time now. Read more on the site; then did cache clear, factory reset via recovery and then also flashed back stock MM firmware - everything successful but still getting random reboots.
Just to mention, the tablet has recently had a brand new original battery so that is not the problem. It was working fine before I attempted the TWRP/Adoptive storage patch or stock firmware flash and now getting random reboots (sometimes right at startup logos and sometimes soon after booting up).
This appears to be a very common one on these Samsung tablets so no clear reason anywhere why it happens. Any suggestion for a quick fix for this please. I am getting random reboots at the moment all the time since I tried flashing the recovery/patch/stock firmware. Any help would be appreciated please...
update
Just to provide quick update and info:
Purely by hit and trial, I have found that if I keep hold of the power button (pressing it constantly since power up), it goes past the initial boot loop consistently and boots the device up. But then, once it hits the limit for holding the power button (think 30 secs), it vibrates and turns itself off (which I think is normal behaviour). So I thought this is interesting to share as not something I have read anywhere else. Not sure what difference it makes to the startup by holding down on the power button but that does not appear make it loop. Of course, this is not a solution as the tablet eventually shuts down after 30 secs of holding the power button.
The power button itself seems fine and not broken/damage or anything - clicks fine and solid and works fine every time. Also the random restarts does not happen in recovery/download mode so I take it the power button is not faulty as else, it should be happening for everything.
Again, requesting everyone for some help please as I am a bit stuck what to try next.... thanks in advance!
anyone pls...?
Bump again... in the hope one of the experts will jump in to help!!
Thanks in advance
I'm experiencing the same exact issue, The tablet will power up to the setup screen and I can almost finish the setup process but then it vibrates and powers down. PLEASE... someone, chime in and help with this problem.
Thanks In Advance
