[Q] Cant even get into download mode - reboot loop - Galaxy Note II Q&A, Help & Troubleshooting

ok so it got a bit wet, then started rebooting randomly once or twice (when i say a bit wet, it was some sticky kids medicine)
it stopped doing that but the power button was a bit sticky so i applied suction to get any residue out of there and the button stopped sticking.
but now its on a reboot loop.
it goes to the gt n7100 screen, then goes off then back to the n7100 screen.
ive tried going into download mode, but it gets to the "warning custom OS" screen, i press volume up and it just restarts again.
ive tried plugging it in to charge and it brings up the battery icon and a circle wait timer then after 10 seconds or so it flashes again to the wait timer (which is not turning)
what else can i do to make it work? is there not a pin button for factory reset anymore?

It got wet. So it's not a software based problem.
Return it to service center and see if they can fix it.

[Q] NO WAY! This is not possible?

I was talking on the phone and BOOM it resets.
It started reloading and can't! WTF!? It just gets caught. The Samsung logo comes up and then the darkside boot animation (been running this rom for a few weeks). Then it blacks out and does these intermittent vibrations like it's trying to boot but just stays black.
When I take out the battery and put it back in, it attempts to load itself without me touching any buttons. After the boot animation it goes black and does a single vibration that pulses every other second.
I've changed the battery several times, plugged in, unplugged, everything I try can't stop this.
I attempted to get it into recovery. After I get it there, it resets within seconds and puts me back to the same place. There is no way to get into download mode as it goes into this weird loop as soon as I plug the phone into USB.
Ever heard of this? What do I do?
Your explanation sounds like a hardware issue. your power button is being pressed and held without you doing it.
1- is the phone in a case? take the case off.
2 - if no case, did you get the phone wet? somehow the power button connection is being activated.
3 - power button is stuck.
Possible solution - remove battery then press and release the power button several times.
Let me know if that solved the issue.

stuck in blank screen vibrating bootloop, stock, t989d

Hi i have a telus T989D, stock unrooted. I was trying to open a picture in my gallery and my phone restarted, then it showed the samsung loading screen and at about 75% it restarted again. Then it just vibrated, paused, vibrated, paused, etc. and its a blank screen. I tried holding volume down + power and it takes me into download mode warning screen, but it shuts itself off before i can do anything and continues this blank screen vibrating loop. ive tried pulling the battery, but the second i put it back in it loads the samsung screen, restarts and continues the loop. if i cant even get it to stay in download mode is it even possible to fix this?
sounds to me like you have a sticky power button (very common) on these phones/samsung !!! so if wiggling a took pick in there and un jamming it a bit then you need to send it in try leaving your battery out for like 10 min take out sim cards memory everything leave it sitting ..... then try again
There are some fixes for the sticky power button here:

[Q] Hard soft brick???

Until two hours ago my I747 was running fine. I picked it up and attempted to unlock it and got nothing. I decided to try to pull the battery and do a reboot, it got to the KT747 splash screen from the kernel I run and went black. I tried booting into recover and download mode. Recovery mode gives me the little blue text at the top left of the screen indicating its booting to recover, black screen and nothing. Download mode pops the warning screen and 2 seconds later, whether I press up to continue or not, it goes black screen as well. I was running a rooted version of TW 4.4.2 with the TW version of Ktoonsez most recent kernel. I have been running this combination for over a week with no issues. I tried creating a 16gb debrick sd card but the phone doesn't want to stay on long enough to boot to anything. Any suggestions would be greatly appreciated. If there is any other information I can provide, please let me know and I will add it.
****edit for more info*****
I tried having odin open on the pc while i booted into download mode. Removed battery and usb cable from the phone, inserted battery while holding vol down and home. Download mode came up, pressed up to enter and quickly inserted the USB cable. Odin detected the phone and one second later shows it was removed. I have tried multiple USB cables as well.
****edit for still more info****
After several hours of cussing and google searching I came across a thread that described my issue perfectly. The solution turned out to be a stuck power button on the phone. Just like my phone, the one in the thread would boot immediately when the battery was inserted and shut off at the splash screen. Recovery and download mode both did the same, as does my phone. The site suggested rapidly tapping the power button to jar it loose. This did not work for me. Neither did the suggestion of sliding a finger nail into the gap between the chassis and power button. I went so far as to disassemble the phone and remove the physical button from the case. I put the battery back in and the phone booted immediately. The problem persists, the phone shuts off completely after a 2 - 3 seconds. This occurs with the battery in or with the battery out on USB power.
Sometimes messing around with the power button will work, but not always. Its only a temporary solution in most cases anyway.
The switch appears to have gone bad and will need to be replaced. I believe the part is only a few bucks if you want to DIY. Otherwise most local cell phone shops can do the repair relatively cheap from what ive been told.

[Q] Display and touch screen major issues following lollipop update.

Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:
Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.
If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

Phone not bricked, but usually won't boot in any way

Hello everyone, thank you for your time.
TL;DR: Phone boots into download mode up until "Downloading...", recovery mode until "RECOVERY BOOTING," and can only boot right when I put the battery in. The battery is fully charged, and I can boot up until my home screen only once so far. Will a jig fix the issue, or should I try to get the phone replaced by TMobile warranty as I have before?
I have a Galaxy S3 from TMobile, and have been running CyanogenMod for about a year now. 2 days ago I flashed a nightly release, which I assume was unstable. Yesterday, my screen was on and then my phone turned off (low battery, but 99% sure it was a crash rather than a power off), and did not boot up again. After attempting to pull the battery out, charge for hours, turn on and plug in (in different combinations), the furthest I could get was a couple of seconds of the CyanogenMod Galaxy S3 logo initial boot screen (not the rotating splash screen).
I took my phone to TMobile today and was about to get it replaced until I realized I didn't mask the flashes.
The last time I was in an exact same situation with the same phone model, and my flash counter was still showing custom firmware, yet I did manage to get it replaced effortlessly, but I didn't want to risk what was a possible fluke again.
I get home, and here's my current situation.
The only way the phone boots up in any manner is when I take the battery out and the charger is not plugged in. Here are the scenarios I run into:
1. Boots into download mode, can press VOL + to get to the "Downloading..." screen, then shuts off 2 seconds after.
2. Boots into recovery mode, only up until "RECOVERY BOOTING", then shuts off.
3. Boot by pressing power button, plug charger in, shows grey battery icon.
3. Boots into download mode, can press VOL -, either shuts off, OR
3b) Only after tons of tries, it booted up all the way up until my actual home screen, then shut off.
I can't have the charger plugged in while booting (pc or wall), and I can only boot right after I put the battery in.
Are there any suggestions as to what I should do? I was thinking of buying a jig from Amazon, but I don't know if it is hard bricked or not. Should I just attempt to get it replaced under warranty once again, even though it shows the flash count?
Thank you very much!
FIX: STUCK POWER BUTTON PROBLEM
So, one thing I didn't check. Take the battery out of the phone, wait about a minute. If it buzzes as if its powering on, that means that your power button (either the actual button itself or the switch on the mainboard) is stuck.
Solution: Smack the power button with your battery until your battery has a (small) dent. If it doesn't work, smack it a couple more times. Took me 2 tries, second try, phone didn't buzz when I put battery in. I press the power button, works like new. Absolutely....ridiculous
