Phone hangs and cannot shut down - Galaxy S6 Q&A, Help & Troubleshooting

Hello I have a Galaxy s6 model SM-G.920F that hangs on the main screen and cannot shut down. I cannot go into recovery mode either to factory set it. So, I flashed with stock firmware from sammobile and phone works. I then hard reset it from recovery mode and phone boots and everything fine. Then after a couple of minutes hangs again and same problem. Someone pls help...thank you

Have you tried booting into safe mode?

How do I do that? Please tell me

Reboot the phone. As soon as it starts to boot, press and hold the volume down button until it comes up. You should see Safe Mode in the bottom left corner.

Booted into safe mode, still hangs on it, any ideas?

If it was a US model I'd say go to Best Buy for a software re-flash.

Stuck in safe mode help

I need help getting the wife's phone out of safe mode. I rooted the phone and its on a stock rooted 2.2.1 rom and if you do a restart it loads the the boot loader screen and I can pick recovery and then restart but it still boots in to safe mode says it in the bottom left corner. She has apps and stuff on there so trying to get everything back but not really sure how to get this fixed. Also have pulled the battery out and still no luck going to safe mode. I guess if I can't get it fixed can I install a factory stock rom back on it to fix this? I know if I do she will lose everything. Just need the best option to get this fixed.
Thanks
"Safe mode"???? I've never heard of that.
Yeah it the bottom left corner of the phone it says safe mode it says it down near the home icon and over top off the circle with the up arrow. It looks like it may only load mainly core apps and some others but not all kind of like a windows pc in safe mode. And like I said I've pulled the battery out and rebooted and still says it and also from the boot loader screen picked recovery and then restart and once booted it still says it in the bottom left corner.
I gotta ask... Are you sure this is an Inspire?
Yes this is a inspire. I'm at work and once I get home I will use my inspire and take a pic of the screen with it saying it and upload it here. Mine I just got and haven't rooted it yet still a little unsure on the new way so you may see some questions from me on it a little later.
I have seen people stuck in safe mode . The guy was stuck in hboot and would not boot up. somehow he managed to boot it up but he said it was in safe mode. he was going to flash the gingerbread ruu, but havent gotten an update.
you posted in the thread gene it was titled bricked.
as to the question isse here. you might have to flash a new rom, though not ideal. But google does a good job of backing up apps/settings
I'll be damned:
http://www.technipages.com/htc-hero-start-in-safe-mode.html
This seems more applicable to the Inspire:
http://www.myvusers.com/forums/htc-thunderbolt/7426-safe-mode-htc-thunderbolt-adr6400.html
I'll try and see if one of these works. I think I read some where about the hero and tried it but may not have. So will give it a shot.
Thanks

Apparently the hero has a "hard" menu key. The Inspire does not so you have to ue a different "hard" key. I tried it and the thunderbolt method works for the Inspire (using VOL "hard" key).
It was mentioned over on #liberatedAria that you may have a stuck VOL-UP key so it goes into safe mode every time you boot.
Ok thanks Gene I'll try it for the thunderbolt method. Like you said the key maybe stuck. So when you powered back on you held power and vol up key and it turned safe mode off for you then? Just checking cause not sure if vol down does any thing or you always use the up vol.

No, I just rebooted. That's why we thought the key might be stuck.
yeah I think it is the vol key stuck as soon as you try to turn phone on it just goes to hboot screen. Sense I do believe the volume key is stuck does anyone know how hard it would be to fix this problem? I'm sure I can order a new volume button on ebay but not sure that will fix the problem. I need to get it fixed so I can get it back to factory rom so I then can take it back to AT&T cause I do have insurance on the phone but don't believe they will take it back cause of it loading to the hboot screen menu.
Can anyone give me any suggestions on what to do to get this fixed? And would it be possible to use the stock rom or stock exe file to put it back to stock form to take it back to AT&T to get it repaired or can I repair this problem myself by ordering a new volume key off ebay.
You should try gene pooles s-on tool in the Dev section. Since you have insurance I would just have it replaced

I think I bricked my Samsung Galaxy S6 SM-G920I

Ok, so I tried to root my phone using odin and cf auto but at the end of the process when my phone got rebooted I was stuck on the logo screen for ages and this small red text showed at the top saying something like recovery is not seandroid enforcing. So after searching through solutions I tried formatting the phone but when I tried to go into recovery mode it just rebooted back to the logo screen. So I then tried to reinstall the firmware but after doing this Odin said failed and then my phone got rebooted and is now stuck on the message "An error has ccured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software." But Samsung Kies and Smart Switch says my device is not supported and when I try to go into recovery or download mode the phone just turns of and goes back to the error screen. Can anyone please help me. This is a new phone and my parents would kill me if they found out I screwed it up already.

Put your phone in download mode and use odin to flash ROM. It will work.
Good luck
1) smartswitch or kies wont work at all because you already tripped your knox
2) recovery is not seandroid enforcing <- this text shows you have custom recovery installed.
3) you possibly didnt turned knox off. settings>lock screen and security > find my mobile> there will be an option to switch it off
now solution
1st of all you havent bricked it! its soft bricked and not hard bricked(hard brick wont even turn on)
what you can do is let the battery drain off totally charge it and try to put it in download mode > odin > flash stock rom first(important step).
from there try to turn it on if it does you great. and dont use cf auto root if you are not familiar with it download some other roms which are way better than stock touchwiz,pre rooted and way better than it(like the note5 rom for s6 by arter).
by the way keycombinations >
downloadmode = vol down+home+power to switch off download mode vol down+ power only
recoverymode= vol up+home+ power
if you can put it in download mode follow my steps and hopefully you can,just keep trying

My phone wont go into download mode. When I press the button combination, the phone reboots and goes back into the screen saying the software error again. And the first time I tried to flash stock the phone is how the error message came up.

Ok so I let my phone completely drain of charge, then the second I put it on charge, the phone goes to the software error screen. Download mode just reboots phone into the error screen and recovery mode doesn't seem to do anything. Ill see if Odin recognizes the phone though
Ahm probably you missed something that could help you resolve your issue in much less time.
1. Press Vol Down + Power Button for 5 seconds until it reboots. After the screen is off then quickly switch to Vol down + Home + Power button to access download mode.
It is the key combination to safemode but it your case, it will just force restart your phone. No need to drain your battery.
2. Maybe most of the newbies always missed this part before doing anything to their phone. Backup (either on smart switch or Nandroid*best option)
3. You need to have proper samsung usb drivers installed and check in odin if your phone was recognized.
The only thing I see from your first post is that the firmware installation (odin) was interrupted. Please let it finished installing before doing anything in ur phone. Check faulty usb ports/usb cables to ensure your pc/laptop works well with ur s6.
Let us know how if u still encounter any issues.

do as the guy above said in 1st step thats a key step to put it in download mode
Thank you guys
The phone is all good now. It turns out that the software error screen was also the download mode. So I flashed the stock rom and everything is fine now. Thanks for the help.

Even though knox is tripped you can use smartswitch.
I know this because I have done it.
I rooted my phone, installed custom kernel, etc.
I then broke the screen, and since it was a hardware issue, I got it covered by my phone provider. (I am in Aus, we have different warranty laws compared to the USA.)
But I had to return it to stock. So I used Smartswitch to do so, even with knox tripped.

S6 Screen working on recovery mode, but not when phone boots

Hello,
I accidentally dropped my Galaxy s6. When i picked it up, the screen was blank.
Fearing the worst i rebooted the phone. The screen works fine when in recovery/download mode, but when the phone boots normally, it doesn't show anything. The odd thing is that the when it boots normally, the phone appears to be ok... i can press the Vol+ and Vol- and get the usual beep I would expect.
In recovery mode the screen is fine. I can see the bright greeny blue glow with white writing etc...
Please can anyone advise on some tech support for this? I can;t see that the screen is broken becuase it works fine when in downlaod.recoivery.
Help me Obi Wan! You're my only hope!

SM-G955FD can only access Download Mode

Hello everyone,
I apologize that my first post is directly asking for help but I've spent days reading and trying to figure out my issue to no avail.
I have a SM-G955FD and a few days ago it just turned off (battery at 40% and charging) and wouldn't turn back again (stock firmware, never rooted).
Recovery Mode (Pwr + Volume Up + Bixby) doesn't do a thing (Black Screen)
Download Mode (Pwr + Volume Down + Bixby) opens the Download Menu, if I proceed (Volume Up) , the device shows up in Odin.
I tracked the same firmware I had to flash it and found it. I load up the BL,AP,CP & CSC and proceed with flashing the device through ODIN.
Everything completes and I get a "PASS" from ODIN. However, when my phone reboots I get a blank screen with no vibration or logo or anything, it seems as if rebooting is actually turning the phone off.
Do you have any suggestions on what I can do? The device is still under warranty but I'd rather try everything within my ability to try and fix it.
Thank you so much folks.
Edit #1: Took it to a Samsung Repair Center and they told me I've voided my warranty because I installed a custom firmware. I clearly show them the "Download Menu" and how it's clearly marked "Official" & the Warranty Void bit/hex is 0 (I only flashed the same exact firmware from Sammobile using Odin, nothing even related to rooting which they claimed I did). They tell me this doesn't matter and that it's now out of warranty and if a software flash doesn't work then they would have to charge me 380$ (American Dollars).
I have a gut feeling that it's a software related thing at this point but my realistic assumption is that since the power button isn't causing the phone to vibrate it's probably a hardware issue.
What do you guys think?
I really apologize for the long posts, but I'm really pissed since the phone is barely 6 months old and I bought it unlocked.

did you try soft reset ? this is how :
To soft reset a frozen Galaxy S8 or S8 Plus you need to hold the power button and the volume-down button for roughly 7 seconds. Let go of the buttons once you feel the device vibrate and see the Samsung Galaxy S8 logo on the screen. Your phone will then reboot, and hopefully, start working properly once again
One thing to note: On the forced reboot/soft reset, you will be given four (4) options. Use the volume keys to navigate, and the “Bixby” key to select. Option 1 will do a normal boot, as if you’re turning the device on.
i hope your phone work again... try another Samsung repair center and don't explain anything just told them that your phone worked fine and one morning this problem appears... and nothing else don't mention Odin flash or....
i think this its storage problem or a hardware fail...

Hi there! No solution other than changing the motherboard. Went to another repair center and they did that in less than 2 hours and around a day to complete the water test.
Good luck

Bricked my S10e one day after getting it, i need some help

So, today my dad bought me a new phone because i needed one, an S10e. And i, like a massive idiot, decided to flash it with TWRP to try and root it. It worked, sort of, TWRP recovery worked fine, but the phone was in a boot loop when it wasnt in recovery. So i decided to flash the stock firmware, only that it got stuck on the System part when i flashed it with Odin, so i had the brilliant idea to disconnect and try again, except i ended up bricking the entire download mode. I cant turn off my phone, nor can i go into recovery mode, everytime i try to turn off the phone, it boots up back into the download mode with the Smart Switch error, no warnings, no cancels, nothing. Just the error screen. Now if i try to flash it again with Odin on the error screen, it gets stuck on Boot.
Am i royally ****ed to the point where i cant send it to the store? I got it today so i thought i could take it back to where i bought the phone for a replacement or repair, but if not then i honestly dont know what to do. I tried using Kies or Smart Switch for restoration, but they dont even recognise it.
Ooohh...So sorry. Im going to look around for some help for you.
I used to do this but havent the need in years with the new technologies.
Better to ask over at the Magisk root thread in the regular S10 forum.
You can call Samsung and if its under warranty they can walk you through or do it while connected to your computer.

you should be able to get into download even after that error
just take out the usb cable and hold power + bixby+ vol down to force reboot then just hold bixy and vol down and plug the cable then you are back into download mode and restore your phone. It's not messed up
Search on youtube s9 download mode.
:good: Help it rise Undertaker21.
Try to boot in fastboot and reflash all partition.

Thats the thing, if i hold vol down and power for the 7 secs to get out of download mode, it automatically boots itself back into download mode without any "press vol up to continue" and stuff, its just the constant "an error has occured while updating system software" screen and absolutly nothing else, and like i said, i tried to reflash all the firmware back to stock, but odin just stops at Boot, and a message appears on the error screen saying a PIT check failed (thinking about it, i could just be that i downloaded the wrong firmware, i dont actually know what country the phone was made in, and if it helps, i bought it in Lithuania, and i unlocked it with a Lithuanian SIM card, so im not sure what country firmware i should get. One strange thing: i remember looking at the display case at the salon i bought the phone at, and it said that the phone has the Snapdragon CPU chipset, but if that was true then i wouldnt be able to have unlocked my bootloader for Odin in the first place)

Use smart switch, please follow the instructions in this video
You need IMEI and Serial number which can be found on the box of your phone or it will be embedded in the back glass
I believe on the newer version of smart switch you have to enable device Initialization from the preferences tab

yes, i have, and again, nothing happens, it just instantly goes straight to the error you get when you **** up an odin flash in the middle of its work
This is so odd. Ideally a picture of the error screen would really help here. It's usually pretty darn difficult to brick a Samsung phone.
Have you tried using a different USB cable and PC to do the Odin flash?
