[Q] Infinity bootloop. How to solve it?

Hello,
Today, while shopping I saw that my 8s is turned off and I couldnt turn it on. I was suprised, because few minutes before, baterry was 50%. Still, I cant turn it on.
When I plug my phone to charger - bootloop starts. When I unplug phone from charger, phone goes off and I cant turn it on. Turns on (and starts bootlooping) only when pluged to charger.
I can go to boot loader only when pluged in but it don't give me anything.
I putted off sd card and sim card and tryied to turn on - nothing changes. Still bootlooping.
Phone didnt have any contact with water - I'm sure.
Any clues? I'm very disapointed because I bought 8s just one month ago.

Have you tried a Hard Reset???
Warning! All user data will be lost!
1. Turn the power off.
2. Press and hold the VOLUME DOWN button, and then briefly press the POWER button. Release the VOLUME DOWN button when you see an icon on the screen.
3. Then press the following hardware buttons in this sequence: VOLUME UP > VOLUME DOWN > POWER > VOLUME DOWN.

Ofcourse I was trying. But when phone is unplugged from charger it doesnt respond at pushing buttons. Its like brick.

I assume you already tried to fully charge your phone??? Do you use the original power adapter and the original cable??
Is the Hard reset possible while the cable is connected??
Mine is showing a big exclamation mark "!" when I do a hard reset with the button combination....

Did you have wifi on when this happened?
Have you tried the actual hardware button combo to get into recovery?
Perhaps pull the battery greater than 30 seconds or a minute then try powering it back up.
Pull the battery and then plug it in without the battery to see if you can get to "download mode" I believe it's called.
What ROM?

I would second this. It sounds like Sudden Death Syndrome Bricking.

Now it turns on when volume+home and power are pressed but only last a few secs and turns off.

Sudden death brick? First I've heard of that issue. Hope you have insurance!

FWIW, I had something similar to his happen to me today. It turned out that despite showing a full charge on the battery, the battery simply ran out. I plugged it into a charger for a while and it fired right up.
To be clear the symptom I was experiencing was that my screen shuttered and then my whole phone died. When I tried to pull the battery or power on in any way, I'd get a short vibration pulse and then it would die again. I also cycled through the different key combinations trying to connect it to my computer, but with no success. Once I saw the red led charging indicator, I knew I wasn't bricked, so I just left it on the charger and let it continue to do the vibration pulse repeatedly until it had enough charge to display the on-screen charging indicator. Once I had that, I let it go a while longer and then tried to power it on and BOOYA! We're back in business.

Thank you so much, I almost pooped a donkey when this happened to me. Could it be a sign of a failing battery?

Same issue - power button culprit?
Hi,
I am having the same issue. My bud has the same phone and I swapped batteries, still boot loop. It seems after some research that the problem is the power button contact not opening. I have seen two videos now where people de-solder or snap the power button off (after metering it) and softboot the phone via their PC to recover their data...
I will be switching out my board for my friends tonight to see if his button panel will do the same thing...
Long troubleshooting process for this one.

It might be a power button issue when restarting and showing galaxy s3 screen tap on power button with a lil force like you would on a table. Then don't touch power button when up

Thank you So much.I was in the point of going to buy another Phone!

My vibrating brick was caused by dead batter too!
Came back here just to write this!
I was ready to toss the phone in the toilet... and then saw this thread.
Exactly my situation, got the phone to charge for a bit (on wall-USB, not PC-USB), trickled in a % or two of battery life and now I'm back in action!

I'd say just leave it plugged in. I've had this happen to me in the past. You should try a new battery.

Please help!!!

I second the dead battery
My phone was plugged in and battery showed a full charge. In fact it had just woken me up with the alarm. When I went to take it off the charger (100% battery on the meter, mind you), it turned off instantly. Attempts to turn it on only resulted in intermittent vibrations with no display. I tried plugging it in and charging light would come on for a few seconds, then turn off. Same as if no battery was in it.
I tried all of the usual recommendations like boot into recovery mode using Vol Up + Home + Power button, tried removing battery/charger and holding power for 30+ seconds, etc. None of it helped.
Fortunately this was a battery I had purchased about 3 months prior. I still had my original which I threw in the phone and it booted up instantly. The battery that had been there was fairly new and had worked without issue until it just died on me. My original is now back in place and working.
Don't overlook your battery! Your phone may very well be okay.

A new message for other GS3 users having this problem (2016)
SOLVED! as in a few minutes ago as of this post
I was sure that I just experienced the sudden brick of death because of all the signs pointing to it. I couldn't boot to any mode nor get it to recognize on a computer.
It wasn't the battery since it was still 50% full-- tried taking it out of the phone and straight turning it on with a USB cable. I got the red LED indicator for a short moment but that too shut off, so it definitely wasn't the battery.
After reading the comment about the power button I thought I should give it another go.
Solved my problem a few minutes ago by pressing down really hard on the power button!
I also gave my phone a mild whack on the back where the logo is/should be if that contributed anything.
My phone almost gave me a heart attack. Try this and see if it works for you. :good:

Why battery consumption while turned off?

Looking at my battery consumption chart, I show a steady declining slope during the time when my phone is powered off.
Is something active when the phone is shut down? I don't understand the downward slope during the night hours when I've shut down the phone for the night so I can go to sleep. The phone is unplugged and does the shutdown routine fully.
Specifically the battery consumption shows a perfectly straight sloped downward line decreasing for about 7% (from 87% down to 80%) over about 6.5 hours. Then the line gets curvy/steep to indicate when I turned on the phone. It's a Sprint phone.

Can you post a screenshot? I've always seen it show up as a gap. The phone is completely off and not just the screen, right?

Your phone does not go into full shut down mode with Android when you turn it off. It goes into a deep sleep. When you hit the task manager, you will see a list of apps still opened.

I think he said while the phone is completely off and not sleeping

He said powered off. But I'd agree that the symptoms sound, to me, more like just hitting the power button briefly to turn the screen off.
KingFatty, I apologize for asking. But just to make sure we are all talking about the same thing, when the phone is powered off, and you hit the power button, does the screen immediately turn on, and instantly bring the phone back to a usable condition? Or does the phone boot up again over the course of 30 seconds or so, before being usable?
When you say it's powered off, I would assume you mean you held the power button until the prompt came up on the screen, and you selected Shut Down (or whatever the wording is), and the phone took 15 seconds or so to power down completely. In that state, I'd expect to see gaps in the battery graph, during the time duration that the phone is powered down. And I'd expect the battery to not drain measurably while powered down fully.
Please forgive me if this is dead-obvious, and you really meant actually having the phone powered down completely, but still observed the battery discharging. In that case, I'm afraid I don't have a guess of what's going on.

Yes, it was "off" because of quickboot. Quickboot has been in Android for some time now.
If you really want to test it, do a battery pull. I guarantee that your battery will not drop if you do so.

Yes, when I power-off the phone I hold the power button and the menu pops up for power off, restart, or airplane. I select the top option, "Power off." This is further confirmed in the mornings when I power on the phone, I need to hold the button for a bit, then the phone comes on and displays the LG logo screen, and then prompts me for the device encryption PIN (need to encrypt the phone for Exchange email rules imposed by work).
Here is a screen shot showing the very slow consumption during the hours the phone is "off," with the discontinuity at the far right when I turned on the phone:

EDIT: Is there a way to turn off the "quickboot" or whatever? My previous phone had an option to turn off the quick boot so I felt the phone was "fresher" that way after a boot up. However, is the quick boot feature of this phone so good/mature at this point that it won't make a difference whether quickboot is enabled or disabled?
I have plenty of time in the morning to let the phone boot up so I'm in no hurry to need quick boot, so I'd prefer to disable it if that would 1) stop the miniscule battery consumption while powered off, and 2) make Android/apps even more responsive/fresher due to really actually booting up fresh, instead of quick boot

[Q] HOX stuck in bootloader/NO Rom/NO recovery

Hello all.
I think my HOX stucked in bootloader, and how I noticed there is no rom/recovery on my phone.
I already tried bunch of ways, but nothing worked.
First I need to re-unlock, but it does not work. When the screen comes up, I navigate with vol buttons, and when I want to confirm with power buttom, nothing happens. without power putton can I re-unlock?
Or someone can guide me out?

Someone can help?

First of all you need to get in fastboot-mode, but since your power button doesn't do anything, means you probably can throw it away....
And how do you know there is no recovery / rom on the device?
Kind regards MrMaddTraxx

I know, because if I wanna boot, nothing happens, simply only bootloader comes up.
And am no sure about recovery, because my power button is ****.
I ordered a power " cable" and i hope that will work otherwise i can throw away..

The solution would be getting the power button to work. Get your HOX out of it's plastic housing by pressing the white part under the screen backwards (carefully) and push the screen out.
When the bottom part is out, you have to shove it a bit downwards (the top is sitting behind the white part, so it has to come down first).
From here on out you will be able to see the part where the power button would be pressed.
So you have to be sure whether the power button does 'click'
or if it is more like a bad HBOOT you have installed (which stops the Power-button in a way.)

My HOX already in parts, and I noticed the power button cable was damaged, when i took off the black " folio " from the button i saw it was damaged.
So I bought a new cable, and I hope it will solve the issue, because I did NOT changed my HBOOT, so I think this can be my issue.
I bought a power button cable like this:

Just an original one.
Whenever it arrives I can tell if it works or not.

One quick question: How did you know that your power button wasn't working? Because that would mean that you weren't able to turn your device on or off in the first place

I had to take off the battery to turn off the phone. Also i can not apply unlock bootloader screen so i checked the cable and it was damaged.
Btw when i plug my phone with usb to my pc automatically bootloader comes up.
So this is why i no need to use power button for this.
Also i already had power button issue with other phone so i know how that works ?

Entered recovery mode for no reason. Can't get out

When I woke up I saw my phone like this. Can't select any of the options because my power button has not been working something like 2 months. I was using the accessibility menu for the power button.
What can I do now? Is there a way to flash a new room without using the power button? By the way I was using Stock Android without root. Please help me. Thank you.

That's a subsystem of your recovery called "Rescue Party".
Your power buttton isn't working? So also rebooting or turning on your device (in case it turns off due to 0% battery for example) won't be possible?

It doesn't have physical home button. I never dropped my charge under %5 so never needed to turn it on. I was restarting weekly via accessibility menu. I was thinking that if it willl turned off I can connect to pc via usb and use some boot app. But now can't do anything.
By the way the reason I am not getting repaired my power button is because I live in Turkey. Pixel or pixel parts doesn't in sell here.

Well but without power button the device won't power on / reboot using hard keys.
Do you know what exactly is broken? If you disassemble your device a bit you can see a little "plate" which is very thin.
Maybe this thing is still working but your button itself doesn't touch/press it correctly.
If you know how to disassemble your device (or want to try out. You can't really do that much wrong as long as you unplug cables on the corresponding place and you unscrew every screw) you could try to manually press the little (circular) pinpoint (located on that little "plate") and see if it works to turn on your device.
Else I have no further ideas, unfortunately.

Not without a working power button. So obviously the solution is to get the power button fixed or replaced, because you're dead in the water without it.
