Samsung Galaxy s6 keep shutting down - Android Q&A, Help & Troubleshooting

I'm not sure what's happening to my phone. It keeps shutting down. I can't use my phone if it's not plugged in to a charger.
Anyone with the same issue?

Hi , probably you have bad battery which doesn't keep energy , some issue on your usb charging port or you have some software issue .
Make sure you backup your data , remove all accounts from your phone like Google , Samsung ...
Now , make sure your phone is off , now hold together Vol + , Home button and Power button at the same time keep holding like that and plug charger on it to get the power keep holding like that and once your phone vibrate one release power button but keep pressing Vol - and home key until you see Recovery menu. Do Wipe cache partition and Factory Reset with vol - and vol + key and confirm with power button , once you do that reboot your device and wait for full system loading . Once system is full loaded turn off your phone and remove charger , now try to power on your device and see if the problem is fixed.
If you have still that issue put your phone in download mode the same way as above just this time use vol - instead vol + button.

Hi , if you changed brand new Original and working battery and still it wont work without charger then probably you need to replace new power IC . So is better to send him to some legit Service Center .

How can I get "Download mode" Samsung vibrant

it's dead plzzz help me to fix it
Are u referring to the market? if so... while on market page..press the menu button.
No. Download mode... hold volume down and boot it up, just hold down both until it pops up.
Why is it that there are like 4 different ways posted of how to boot into Download mode on each of the download mode threads but none of them work for me? Is it because I'm retarded and missing something simple or is this phone really that touchy to boot into download mode?
Can someone either post a very detailed account of how to boot the phone into Download mode or post a picture as proof that you have reached download mode successfully so I can at least know what it is supposed to look like should I ever make it there. Prob a good thing I havent made it there yet as I'd just end up flashing the wrong rom and mess up my phone, but it is just really bugging me that people have been posting about this, yet none of the methods in the posts have worked for me.
So far I've tried vol up+pow, vol down+pow, and vol up/down+pow with usb plugged in....Vol up+pow from the phone being fully booted and all the other combinations from recovery and the charging battery screen. What am I missing? Thanks to anyone who can point out my retardation, should it be my fault that it is not working for me.
I have recorded a video for my problem
http://www.youtube.com/watch?v=UYLI8gUN3S4
I was able to root my Vibrant following the thread in here... u gotta hold down BOTH the volume up and down keys AND the power key.... it worked... ( use ur right hand...three fingers to make sure u do it right)
thank you
I tried these
Hold down; {volume both UP and DOWN + Power }
Hold down; {volume both UP and DOWN + Power } + plug in USB
Hold down; {volume DOWN + Power } = Recovery mode
Hold down; {volume UP + Power } = upload mode !
I tried more than 5 millions times what can i do
are there a ways open the internal SDcard then put update.zip and use recovery mode instead download mode ?
I had this same problem also the first day I got my phone...I installed an update.zip that caused the phone not to boot, and for the life of me could not get it into download mode to flash with odiin3. I read all the download mode post, so I thought maybe it was whatever I installed in the update.zip that cuased the button layout to change and thats why I couldn't figure it out. But I returned the phone...and now I still cannot get the phone into download mode.
To my understanding holding vol up+down and then hitting power sends you into recovery, which is totally different from download mode...So can someone clear this up...is the same screen displayed for download and recovery, just with different modes activated on the phone, or do they both show different pictures? Also again...I have still not reached download mode...so if you have a detailed account of how to do such...please post it...
Thanks.
Adb push update.zip /sdcard/update.zip
Do that while in recovery...
Also, I if vol down and power don't work try vol up because you may have flashes a European updated and their buttons are different. For me if flipped the volume buttons.
Oh, and hold the buttons through two cycles seems to help me

Ok, I made a sh**ty video just now, uploading to youtube...
http://www.youtube.com/watch?v=E9LYLoK1Qog
EDIT: The video isn't the best, the camera apparently didn't like the screen much and the lighting is bad but I think it gets the point across... Sorry for being so monotone...
I tried to open internal;Sdcard but I couldn't iconsider that is the solution
I need to give an authorization to do this like : Mount from the notification menu to open the internal sdcard
I wrote some commands by run so appear to me; permission denied
iam so sad
iam going to go to t-mobile store they might solve my problem
I seriously can't get my vibrant to download mode. I have check every combination and no I haven't flssh any firmware. I am in the stock one. This is serious problem. Could it be that it has being block in any way by tmobile?? But them there are some of you that can get into download more very easy. Mine just won't. I can get to recovery mode.
I have tried:
1. hold Volume Down then hold power - vibrant splash screen - reboot after 10 secs.
2. hold Volume Down + hold power at the same time - vibrant splash screen - reboot after 10 secs.
3. hold power then hold Volume Down - vibrant splash screen - reboot after 10 secs.
4. hold Volume Down then press power and release - vibrant splash screen - boot of firmware very slow.
5. All those previous combination's with cable plug into phone
6. All those previous combination's with cable plug into phone and computer
Please help!!!

I'm having the same problem. Simply cannot get into download mode. I have to believe that something else is going on here!
hi guys
I went to RadioShack I told them , I was honest to explain the problem that I downloaded a wrong firmware EU on my phone so the software broken
although they exchange the phone hhhhh
I am so happy now
i really won't back to rooting and "download mode" until hell freezes over
I'll be a polite customer just waiting the officially updates

Just rooting isnt that dangerous... it was the fact that it was the wrong firmware, not just that you flashed the firmware. Either way it's your choice and if you are happy with that more power to you, but the risk of doing anything with the rooting process is pretty low.
I've had good repeatable luck getting into download mode as follows:
1. Power down phone with no USB cable connected.
2. Once you see "good bye" connect USB cable.
3. Wait till battery indicator is visible, and you can see the current charge in green.
4. Hold vol+ and vol-.
5. Press power until screen goes black, then let go of power only.
6. Should see the yellow digger.
Again, your mileage may vary.

I can not thank you enough for this. Although I just took the battery out instead of powering down. So it appears the key is to making sure the battery indicator is on, and that you release the power button as soon as the screen goes black. I tried so many other combinations...even holding the power button past the screen turning black, but I got this on first try.
Thanks!
If you've got ADB setup just do 'adb reboot recovery'...
Is there a differnence between download mode and recovery mode?

[Q] GS2 unable to boot ..might be DEAD

Hi,
While flashing the device got stuck and have to unplug..
now the device is not booting and black screen is displayed...I think the device is dead ... I tried all the option
- volume down + power button
- press power button for 20 - 30 sec
- remove battery for 24 hrs and put it back n try again to boot
but nothing work...
Is there any way to start my GS2 again?
Hold the volume down & home buttons tight & keep them held down. While you're holding them down, press the power button & keep pressing it until you see the start screen. When/if you do, release the power button but keep holding down the volume down & home buttons until you see the download mode screen.
If you can't get into download mode, your next best chance is to try a jig. If you can't get into download mode, I strongly suggest you order one from eBay post haste (search for "Samsung Galaxy S2 jig").
If the jig fails, it's back to Samsung/your telco for repair (probably at your cost given flashing non-Samsung firmware voids your warranty).
What happens when you hook it up to a charger ? And what happens when you hook it up to a PC via USB cable ?

Can you get to recovery or download mode ???
RECOVERY= Vol Up + Home + Power release at splash screen
Download = Vol Down + Home + Power
USB Recovery JIG to enable download mode search XDA buy EBay .

What have you flashed?
Did you come as previous speakers have said in the download mode?

It certainly sounds like the power button is shorted out, send for warranty repair.

this happened to me once. i removed the battery for a few minutes. then put it back and immediately entered the recovery mode. i hold the combo for a long time so that the samsung logo appears for 3 times and after the 3rd time, i released the combo and it entered the recovery mode. may/may not work for you. but worth trying? sounds funny but worked for me unexpectedly!!

Try to enter into Download mode by pressing Vol - Home button and Power button at the same time once you feel vibration or you see first logo fast press just Vol + if not , disconnect the battery , press Vol - , Home button and Power button at the same hold like that and plug the battery in and see if the download mode is showing up.
If is OK reflash stock firmware ....
Good Luck
the problem is that when i try to turn it on in any way, doesent matter if its pwr+volume down + home, or just the pwr button it doesent turn on, the only way i can turn it on is by connecting it to the charger and the loop begins...

Then try to hold VOL + Home button and power button and connect charger .... probably boot images are corrupted ... I don't know if USB jig can help you to get into Download mode ....

i have tried this already, i cannot acces download mode or any other mode...
Are your device somehow getting recognised on PC ?
If is recognised try to reboot into download mode or recovery with ADB:
adb reboot download
adb reboot recovery
Or you can try with another battery if not then you should try with sd sdc repair method but you need ATX box
https://www.youtube.com/watch?v=xsyD09IYbxg
Maybe over the internet someone has made for your device , or to ask someone who is expert for creating custom OS boot files to somehow make sd bootable download mode if is possible ....
my pc doesent read that... ur other suggestion with the atx box looks too difficult... so i guess i can sign off the phone :/

First you must to know that all modification on your device below official fabric state can damage your device whatever is Soft Brick or Hard Brick or Hardware issue ....
From start you know you was doing wrong things by choosing A5 2016 instead A5 2017.
Second you can't expect we are magical people primarily I to solve your problem just like that .
You don't need to give up of your phone , there is Service Repair Center send to someone you trust to repair with Micro SD CDC method or to replace new eMMC chip and reflash new OS on your device ...
Next time do little bit more research before doing anything on your own : ) !
yes i know it is my fault, i dont blame you guys about anything, you did what's right, you tried to help me and gave me a solution of the problem wich i apreciate a lot, thank you

Question How to save a black brick

I tried to root my phone by magisk.
After flashing a patched boot.img, it's failed to boot into system and I got a message that "the device need factory reset". I clicked yes and everything seems ok,I can boot into system. Then I tried to flash img again. So I boot into bootloader. Unfortunately, this time I got a black screen. The phone doesn't response me anymore.
I tried the software repair in xperia companion but It cannot dected my phone when I hold on volume down and plugged in it. I also tried hold on volume up + power but nothing happened. Hold on power key also no response. The led light always black, only become red when I connect it to my pc.
What should I so now and what's my phone's status? I searched something about 9008 mode and edl but I don't know how to check whether my phone is really turn into that status, my pc cannot dect my phone.
Have the same problem, only with the 5 iii instead. Still looking for a fix.
Try to switch the phone off; then just plug it into your PC without holding the Vol- key. It has happenned a couple of times with me that the phone does not want to boot up, with attempts to get it into FLASH mode by holding the key down throwing more confusion into the mix.
I think there is a low battery protection. Make sure the phone is charged up. Keeps the device from death during a flash.
Red led mean a very low battery. Keep it plugged (not to PC but to power adapter) for 2-3 hours and then try again a force reset.
Never, never try flash or other stuff under 50% battery
Also force restart is keep pressed vol+ and power button (or vol- and power button) till you fell a vibration.
Try this after a good charge

It might require experimenting with service modes and different chargers. I had an early Xperia 1 III that bootlooped while charging after setting up the fingerprint reader. It seems that charging is disabled during booting. It has to finish or enter a service/fault mode.
my phone is having this after doing fastboot --slot=b reboot recovery (which actually I had to do fastboot --set-slot=b and then fastboot reboot recovery). the notification light blinks red. have tried vol up + power, vol down + power, and vol up + down + power for like 30 seconds and nothing

I feel sorry for you brother...such a nice device...OK let's talk what happened, the state now your device is in is called hardbrick and it had a corrupted bootloader or no boot loader, but your device is still alive, in your PC in device manager it lists as Qs USB mode with some number after it like qsusb9008...now this device can only be brought to life with the help of a blankflash file which can flash your boot loader in snapdragon service mode...actually no snapdragon can be hardbricked permanently now you need appropriate blankflash file for your device.. Please don't open the device if some repairmen suggests to do JTAG nothing is necessary all you need is blankflash file which is shared to only Sony testers groups.... Who tests ROMs before release and they hardbrick so they share those files to them.... Please don't loose hope....it takes time but certainly it can be bought back to life... And dont try any flashing utility as there is no functional boot loader on it now and nothing will work...Sony won't provide that for sure and they will say then can only solve by mother board replacement ,don't believe therm your device is perfect it only needs blankflash file as it entered into final safe mode... I ain't regular on XDA if you need any info contact me via my mail [email protected] g ma I'll .com
Have any of you tried this - https://developer.sony.com/develop/open-devices/get-started/flash-tool/download-flash-tool/
ok in my case it was the charging IC
