[Q] Random boot loops - T-Mobile Samsung Galaxy S II SGH-T989

Hey guys, I'm looking for some help. Lately, regardless of which rom I've been on, I've been getting random reboots. I've been on embryo, pac, and aokp. When I was on PAC, I went into a boot loop for a few hours until the battery died. Once I charged it and started it up, it seemed to be fine again. I switched to aokp mr1 build 4 anyway. I thought all was fine, until just now when the phone restarted itself into a boot loop. Any ideas on what's wrong? Thanks.

My only guess is that your battery is starting to crap out.

Have you done s factory reset in your recovery?

Clear battery stats and dalvik cache, if there still a problem I'm pretty sure its your phone battery or processor is fried

Never mind. It seems that my power button is somehow getting stuck without really being stuck if that makes any sense. If I barely run my finger over the button, it gets activated and sometimes stuck, which then procedes to cause the phone to freak out. Should I flash back to stock before I take it to tmobile?

It's a known issue. Search stuck power button
Send yes, return to stock before bringing it in. Use Odin.

I had the same problem with my Sprint S2 ("Epic 4G Touch") - it was "randomly" rebooting a couple of time per week. It gradually got worse and worse, and then I was able to narrow down the problem. I noticed that even barely brushing the power button, the phone would wake, and about 10 seconds later would reboot. I cleaned the switch and it worked better for a week or so. I then sourced a new power switch. (From China - took a MONTH to get here)
Long story short, I bought a replacement power switch, soldered it in place, and have had zero problems since!
Several eBay sellers now sell the switch you'll need.
(They don't include the skills you'll need to properly desolder/solder it, however. It's a tiny switch - only about 4mm wide - and you'll need a good-quality fine-tipped soldering iron and a steady hand.)

CDMA galaxy nexus - unresponsive to touch

Hello everyone,
Basically went to unlock my phone today and touch screen is not responding, however the hardware buttons work fine. Now i've done some research and found other posts of people with the same problem, however their touchscreen problems seem to be fixed(temporarily, at least) with a battery pull.. mine however is still unresponsive after half a day and multiple battery pulls.
Id rather not have to send in for certified to replace an otherwise perfectly working phone.
Any ideas/suggestions would be greatly appreciated!

are u undervolting?
Nope, sorry forgot to say. Completely stock never unlocked or rooted.
Also i tried getting into recovery to try and do a factory reset but when i select recovery i just get the android on his back with the red triangle..
so instead i just went through the steps and unlocked the bootloader and booted up (in order to give me the factory reset without having to touch the screen)
It unlocked and booted up fine but still no response..
No new recent app installed and never had this happen before.
Mine did this after a few days of owning it, and luckily the store took it back and swapped it out with a perfectly working unit. Is yours within a few weeks of purchase?
Figured this out randomly. Remove battery cover. With phone turned on, press on the area to the to the left of the camera lens until the screen is responsive. My screen becomes unresponsive when the phone is dropped and this fixes it.

hrmm this does not seem to fix either. I also have never dropped my phone, although this seems to be worrisome if the issue is hardware related.
@ tmellen i purchased the phone from amazon and am a few days past my return date :-/
Guess ill just give them a call and hope for the best. Thanks for the ideas everyone.
(update) called amazon and they are sending me a brand new phone.
Knowing this i thought i'd try dailong's method again only this time i was quite a bit more "rough" with pressing down on that area, and it actually worked!
Ill still be taking the new phone once it gets here but for anyone who is having this problem there's a sweet spot on the left edge of the phone towards the top (looking at it with the back cover off) there should be a circle shape. press on that area really hard and it should fix.. weird
Experienced the same on my GSM version a few minutes ago. I had to call my mobile to get it to respond. After that it worked again as normal. I'll see if I get this issue again in the next few days. Hope it's just random
Had the same happen earlier to mine and I was on AOKP. I've had this happen to other phone before, shouldn't be a a cause for alarm unless it happens very frequently. Btw, next time it happens to me I'll give that left side of the camera trick a try.
mine got fixed by removing battery.

Soft-Bricked? Maybe?

Hi all,
I'm having trouble with my Telus Samsung Galaxy S2x. I was coming home from work on Wednesday and was listening to music at the time. I turned on my phone, went to text messages, the phone makes a really harsh and nasty noise (the music cutting out) and the phone shuts off. I instantly took out the battery and turned the phone back on again. It got to the boot screen and then rebooted itself and started to vibrate in 2 second intervals on a black screen.
I did some research and it seems like it could be a power button issue? The phone thinks you're turning it off and on again in an infinite loop. At first, I thought it was a battery problem (it still can be without testing a new battery) but I took out the battery and tried turning it on with just the power from the wall, and the same thing happened again. I have however, been able to get into Recovery/Download mode for about 2-3 seconds before it reboots and vibrates. There has also been times where I got as far as into the OS on the lock screen before it rebooted. For the most part it's usually gives up on the boot screen. I should probably note that I'm not a Telus customer, I bought the phone through a friend that worked there and used it on Wind.
My phone is rooted and I have Slimbean 3.0 installed on it - if that helps at all. I was wondering if anyone else had the same problem as I do and what they did to fix it. I'm not too too concerned about the phone (in terms of getting it refurbished). It's the data on the phone that I need to recover if getting it refurbished is my last option. That being said, I am running out of options and any help is greatly appreciated!
Thanks guys!
It is indeed a sticky power button issue. You can get it replaced or u can try to unstick it urself. Don't know where or how much. Try a needle to clean around the outside of the button. Try to rub alcohol to dissolve residue. Try to leave the phone off and water protected while in the freezer for 20-30 minutes and hope for shrinkage that'll loosen the power button. Weird but I heard it worked for someone.

[Q] Water damaged/Bricked??

i dropped my phone last night during heavy rain and forgot about him for about 30-45 mins when i went back out and got it the battery was out. i turned him on and he booted up to the lock screen but then i couldnt unlock it so i turned it off and put it in rice for about 12 hours and i turned it on and it got stuck at the lock screen again. Then it wouldnt boot up past the kernel splash at all nor go into recovery. i got it in download mode and odined to stock but still no go. It seems to be going very very very slow because i just randomlly found it in recovery and the volume controls were very slow and the home button wouldnt do anything. can someone help me? any advice anything to try out? its like its water damaged and bricked.
Edit: i got it to boot but it is the slowest thing ive ever seen. any suggestions?

Sounds like you have a water logged defective unit on your hands. Aside from dismantling the thing and drying out the insides, you probably have a paper weight on your hands.
Sorry man.

thanks for the reply. i guess i need to find a new phone somewhere.
So I ordered a replacment and the guy emphasized on the "as long as its not water damaged" part so does anyone know if theres like a water damage indicator inside the phone that may have changed or show that some water may have gotten in the phone?

Majority of phones have a water saturation indicator on in the inside. However, I couldn't tell you where that is located in our's. You could search a bit on the internet, I'm sure you could find a tear down video or something.

I did a little search and apparently the only indicator is on the battery so I should have no problems. The phone does turn on it just takes about an hour to get passed the Samsung screen so hopefully they wont look too deep for any water problems.
Okay, so after letting my phone sit with no battery for like 5 hours i tried to turn it on and it worked 100%. It was back on stock since i odin'd stock FC09 on it. Then I flashed cwm and restored my backup and i ended up with the same touch screen problems. So now I'm back at the point where i just odin'd stock on my phone and it still won't boot passed the samsung screen. I'm going to take out the battery and let it sit. Can anyone explain why this is happening? Could this one time working event be just a random thing or is it from leaving the phone alone for the few hours I did? Any suggestions or thoughts?

The touch screen problems sound like it's hardware related. As for it not booting passed the sammy screen idk.

Phone shutting down

Where to begin....so I've had my S3 for almost 2 years now and it has run smooth since I bought it. However, about a month ago, my phone just shut off and did not want to turn back on. I tried taking out the battery, putting it back in, using a different battery, connecting it to a charger, but still, nothing. When I would try turning it on, the SAMSUNG logo would flash, the splash screen would play, but then it would just shut off before fully booting up. I tried going into recovery, and I would be in recovery for about 10 seconds before it would shut off. I just tried turning it on for the next hour, and eventually, it turned back on, and stayed on. I thought it was a ROM problem (Was running MOAR v.8) so then I flashed PacMan ROM and my phone was fine. I would reboot to recovery and everything ran great. But....the same problem occured again about two weeks ago. I did the same things as the first time, and it eventually turned back on after about an hour and a half. I change ROMs again and now I'm on SlimKat and things were smooth.....but...once again.....it shut off yesterday. I tried the same things as the previous times, but it would not turn on. My phone would reach the endin of the SlimKat splash screen, but shut off. It has been almost 24 hours since this happened and it still doesnt turn on. Now I am getting worried because it has never stayed off for this long.
Something that may have caused this is my headphone jack replacement. I replaced the headphone jack module myself about 3 months ago, but It was a simple replacement, so I don't think this could be the culprit. I am just lost now and don't know what my problem could be. I have no insurance on my phone, and I am waiting until the LG G3 is released for sprint so that I can upgrade, so I really need this phone to work for another month.
Does anyone know what my problem can be? Any ideas?
Edit: My phone was on the SlimKat splash screen for about two minutes before shutting down. Felt like adding this, maybe it'll help.
Could this be a soft brick?
I really doubt it's a brick of any kind. More than likely your power button is going out. It's very common. You might get away with just taking the phone apart and really cleaning around both the button that you push on from the outside and the actual switch on the inside.
Mind you, this is what I've read and some people have fixed it doing this, but I haven't had this problem...knock on wood.

The power button is probably going out. My S3 which I had for about a year and a half just completely stopped turning on and would only make it as far as the initial Samsung screen when you first press the power button before it would turn off. This problem can't be fixed due to the actual pad is a part of the motherboard. Since Sprint couldn't tell that my phone was rooted because they couldn't turn it on either, the only thing I could do was trade it in for another S3.
Also, when you put the battery in the phone, does it automatically turn itself on without pressing the power button? If so, this is definitely your problem

Thank you both. I will try to clean out the power button and search for a tutorial. Yeah, it does automatically turn on. Does this mean it can't be fixed?
Edit: Fixed it by watching a video that said to just bang the power button side on the table.....Thank you for the help!

There's a myth that the term "reboot" came from the Apple III (yes they had an Apple 3, totally different animal from the II-line). Word was that it would overheat and the chips would actually pop out of their sockets, and that it became common practice to lift the Apple III a few inches above the desk and drop it to reseat them.
Again, take it for what it is, a humorous story, probably not the truth.

Old, old computer term for pulling it up by the boot straps.
As far as thumping the back of a TV... I have a buddy that was doing that with his HDTV a couple months ago. I took the back of the TV off and it turned out to be a loose cable running from the motherboard to the back of the screen...
The moral of the story is old tech solutions can still work!

Well you're lucky. I've tried everything in my trick book with no luck when it happened to me. I tried tapping the side of the phone and picking at the button to see if that would fix it and even went to the extent of taking the phone apart with no luck.
Ive had a similar issue but my phone will have more than %20 battery and just shut off. Sometimes it has as much as %67 left. Then it won't go past the splash screen till i plug it in. When it does turn back on sometimes it has the same amount of battery and sometimes it says that it has 0. Is there any way i can check if this is my battery just being dead or perhaps it needs to recalibrate or something.

[Q] Power Issue on Note 3

I was looking and looking for a thread with a similar issue before posting but I had no luck.
My issue is that when I turn off my Note 3 I have a really hard time getting it to boot back up. This happens every time every single time I shut it off. I hold the power button for about a minute with the battery removed to supposedly drain any power as I've read around but that doesn't help. I'm pretty tech savvy and internally the phone looks perfectly fine. The weird thing is that I don't actually have any issues once the phone is up and running to make me think it's a hardware issue. It charges fine, I get data, S pen is fine, no other issues what so ever. I haven't been able to pin point what I'm doing to bring it back but eventually it does end up booting like normal. I try to pull the battery multiple times with no success. I eventually get frustrated and just leave it alone with the battery removed. When I return it boots up just fine.
Anybody else having this issue or heard of it?
Forgot to mention that the phone is stock. I don't have it rooted or a custom rom installed.
Thats weird. Have you tried reseating the SD card. Sometimes it might bethe memory card.
Why turn it off?
Just let it sleep. I can't remember when I ever turned my phone off.

I noticed you also have a thread which states the same thing and I'm not sure if you figured it out yet, but just out of curiosity did you happen to ground yourself while you were working on your Note 3? This goes for any device in general but it's pretty amazing how much damage the static electricity from just your clothes can cause if you're not grounded while working with an exposed main board. If you weren't grounded while working on it though it also doesn't mean that something automatically happened, I'm just saying it's always a possibility at least. One thing I would try if you're having problems powering it up even just in general, is to make sure it's plugged in and charging first and then hold the volume up and power buttons down together at the same time (and keep them held down) until you feel a vibration and then let go. It will take at least 10 - 15 full seconds (and sometimes even longer) to happen, but that should usually get it to power it up whenever it's being stubborn. Another thing I'd definitely check, especially if it was working fine before disassembling the phone, is the alignment of the power button itself (the button you press with your finger) and the actual power button which is located behind it on a data ribbon that connects to the main board. It's actually kind of a flimsy setup so whenever you reinstall the back frame plate you have to make sure the power button data ribbon doesn't shift, or it can cause all kinds of weird problems when trying to power on or off the phone. Anyway good luck and hopefully this helps [emoji106] [emoji106]

I just mentioned this in my response to someone else in this thread, but it actually sounds like yours has the same kind of alignment issue with power button that I was talking about. I'm not sure if you've ever disassembled yours for any reason or not, but even if you haven't it's still totally possible that it could've happened from the factory and especially if you got a refurbished phone for whatever reason. It's a pretty poor design choice in my opinion because it's such a "fragile" setup, and even the slightest misalignment of the power button itself and the button on the data ribbon can cause the exact same problems your having. Anyway if if you haven't messed with it and it's still under warranty I'd say just get a new one, but if you have taken it apart I'd say first thing to check would be the alignment of those buttons (once you take the back off). I've even had to make a tiny little "shim" and wedge it behind the power button on the data ribbon in order to get it to line up right with the button itself a couple of times, so I'd say it's a fairly common problem with these phones. Anyway good luck and hope it helps! [emoji106] [emoji106]
