Galaxy S7 Edge not bootable, Bootloader Exception, No key combos can power it off - Samsung Galaxy S7 Edge Questions and Answers

Today, I was using my phone, and then it starting running really slow, so I decided to restart it. I powered it off like normal, but then when I went to try to turn it on, nothing happened. So I decided to plug it up, and that's when a screen came up saying the following message in red text on a black background:
Bootloader exception
[ AST_STAT = 0x10000 ]
Exception: do_handler_sync: DABT_EL1(esr: 0x96000010)
pc : 0x8f026210 lr : 0x8f0261cc sp : 0x8f117f60
I've tried looking up other solutions such as holding down power+home+Vol-up, and it does nothing. Holding down power button does nothing either.
Whenever I plug up my phone to my computer, it shows up as "SAMSUNG Mobile USB CDC Composite Device" in the device manager, but it doesn't show up as a drive like it normally would when I plug it into my computer.
My phone was also on android version 7.0 using the stock samsung ROM. I have never tried to root the phone either, so that shouldn't be an issue in this situation.
Does anybody know what I could do to try to fix this issue?

I would use Odin to flash a new bootloader or just a new ROM, but the problem is, I can't find any way to reboot the phone to boot it into download mode.

Haven't tried this since the s3, but maybe it'll work.

Hold power + volume down + home for 15 seconds. It's supposed to shut off from there and attempt to boot up, but if it's still getting stuck on that screen there may be a major hardware issue. USG jig wont work on S6 and S7 already tried before.
You can hold the combinations for longer until the phone reboots multiple times and you see the light blue screen prompting for confirmation to boot download (ODIN) mode.

The buttons seem to be unresponsive. No matter what combination I press, or how long I press, none of them do anything. The phone just stays on that screen until the battery dies. And as soon as I try to boot it back up or plug it into the computer after it dies, it just goes back to that screen.

Yours phone mbo is dead,try to rma phone.Emmc chip is dead on mbo,no flashing will bring him back to life.

[Q] phone to pc screen :(

dont kno if im posting this in the correct section or not but can some one plz help? i was trying to flash the stock files for my samsung vibrant with odin, but it froze so i unplugged and tried to reboot my phone but the phone to pc screen came up. ive tried holding the volume buttons + power to get back to download mode, but it just reboots and goes back to it, can anybody help?
Did you hold the power button down till it disappears and then release the power button immediately as it disappears?
hadnt tryin releasing the power button right away but i just tried and still no luck
Johnz is right. To make sure, unplug & plug back in the usb cable, then hold down the volume keys & power, wait till the screen flashes to black, then release power.
Unplug and pull the battery.
Install battery.
While holding both volume buttons, plug in usb cable.
Have odin ready to go, it seems to help. The phone should power up directly to download mode, once odin sees it, hit start.
i dont get what im doing wrong because ive tried what u guys said but after the screen flashes black when it comes back on its the phone to pc screen. ive also noticed that if i pull the battery while the usb cord is connected the phone stays on at that screen until i remove the usb cord, is that normal?
i just read that if the normal ways dont work that means ur phone is hardware locked. looks like im gonna have to try to send it back to tmobile and hope for the best
Try the above, but also hold the home key. I did the exact same as you, and this enabled me to get back to download mode, so I could Odin.
1) Remove battery, SIM, and sd card.
2) Plug in USB Cable.
3) Hold down Vol +/- as well as home.
4) Press power button for 2 seconds, then release.
This should get you into download mode. Then you can Odin back to whatever you were intending to do.
thanx for all the help guys but nothing seems to be working for me
Just throwing out an update incase anyone was wondering, I got my replacement phone yesterday and it turned out to be hardware locked as well. Tried to flash the fix for it and it failed and bricked my phone! So after calling tmobile they will be sending me another replacement and hopefully that one wont be locked as well
I had the same problem trying to get into Download Mode, I got into download mode and using ODIN tried to flash update. The process was stick for 10 min.
So I unplugged USB and got this phone to PC icon. All I had to do to fix it was to go into download mode again by holding both vol +/- keys and pressing power button until screen goes black then release the power button as soon as the screen went black. If you hold the button longer it will go into recovery mode. Then open ODIN again and re-connect USB and ODIN will detect COM port. However you have to make sure that all samsung usb drivers are installed. That is it. Then flash the update and you all set. The phone will reboot and you are back up and runing.

there is another way to this method, that works on any vibrant i've tried it on and also the captivates, had to help a friend restore his yesterday.
remove battery, sd and sim cards
plug in usb cable to pc and phone
hold down the volume buttons only
pop in the battery
if it comes up to the battery charging icon, pull the battery and put it back in again, should go right into download mode.
again, this works on any vibrant i've tried it on, and the captivate as well, good luck.

[Q] Strange: Boot logo stuck, no recovery mode.

Hi guys,
Been a samsung user since S2, unfortunately ive made people bring me their devices so i can polish them, if not fix.
I got an i9505 at the moment with a very strange issues:
It boots up, hangs on the boot logo.
It boots in Download Mode, but volume up button wont work, i've opened the device and yet the button was fine.
Sometimes just connecting it to the PC using USB, the device vibrates as if it's turning on, though it vibrates every 2-3 seconds. Device is Off btw.
Recovery Mode wont boot, Home Button + Volume Up + Power Button until the thing vibrates, i release the power button, and it just hangs there. Makes me doubt it is not even reaching the point where it knows where the recovery is. However, i got it in to the blueish "booting recovery..." once, but it hanged there as well.
Am clueless here, (re)searching usually brings me near the answer, but it hasnt, i hope the answers here will do it for somebody else.
Edit: since i am doing this out of pure compassion, i have no idea what is loaded inside .

Flash a stock rom base in your country mate via odin and you can download it from here http://www.sammobile.com/firmwares/2/ , then once your done downloading the file, Boot into Download mode (Power+VolumeDown) , Open Odin select PDA /AP , Connect both cables (Wait until you get a blue sign in Odin)and flash away.If you encounter any issues with the firmware (Any FC, Bootloop etc)Boot into recovery mode (power+vol up),Choose to wipe/factory reset. (THIS WILL ERASE ALL OF YOUR DATA INCLUDING YOUR INTERNAL SD CARD! Then choose reboot and you should be good to go! Have a nice day
Mate, is there a way to flash through Odin without pressing the Vol Up button, cause i am not aware of that?
I cant get past the first point of download mode, to actually enter you need to press Vol up.

Hence the thread. There was no other option left.
I usually do this to gain the knowledge for future use, is this a common death for the S4. the user that had it is definitely not a flasher, what couldve gone wrong?

Samsung galaxy s8 (tmobile) stuck in bootloader / odin mode

Hello. I was in the boot menu whilst using my Samsung Galaxy S8 (I was just looking around) and entered the bootloader.
I see a blue screen with a down arrow which says "Downloading... Do not turn off target"
The phone will not receive any input and I cannot turn it off.
I have tried to use fastboot reboot to reboot the device, but the device isn't being detected (In the device manager it says "Unknown USB Device (Device Descriptor Failed)").
I'm sure if the device dies it will boot properly, however I would not like to wait that long. Any help would be helpful, thanks.
just long press the power button (for 15 seconds or so). It will restart.
I have tried this already, a restart has not happened. To make sure, I tried it again and timed it for 25 seconds, the device did not power down.
Try holding both power and volume down.
That worked, thanks.
I've never had a device which required that combination. Perhaps I should have tried it first before posting, regardless, you have been a big help.

[GT-I9515] [BRICK] Help with Samsung Galaxy S4 Value Edition Full Brick

Hi Guys!
I'm new to XDA developers, but I've been following this forum for many years.
I would like to resurrect my old phone, a Samsung Galaxy S4 Value Edition (GT-I9515), witch is most likely bricked.
About one year ago, the device started to randomly reboot, until it no longer powered on (It was NOT rooted or modded).
Recovery also did not work, so I decided to flash the stock firmware with Odin. The flash failed, so i decided to follow a (really stupid ) guide that said that to solve it was necessary to flash a PIT file of the Samsung GT-I9505, so I tried it.
Since then, I'm not able to boot the phone anymore.
What can I do with the phone now? What have I tried? I'll try to be as clear as possible:
Recovery mode:
I can boot into recovery only by pressing VOL UP + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Recovery Mode, 3 different things can happen:
It does not power on
It vibrates, then reboot and freeze in Samsung GT-I9515 logo
It vibrates randomly and then open successfully the stock recovery
Download mode:
I can boot into download only by pressing VOL DOWN + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Download Mode, it seems that the screen freeze at a certain point while loading the recovery mode warning (this warning loads slowly, like a slide from top to bottom). The device rarely fully load the warning, and when it does, when I press the VOL UP key to confirm entering download mode (sometimes it does not respond to VOL UP click for confirmation and i must reboot) Odin is able to find the device but during a flash the Odin log stop at Setup Connection, so the device is not responding.
Normal boot:
Yesterday, after hundreds of attempts, I was able to start the phone normally (I don't know how) , it asked for the initial configuration and language, but when I turned it off, the problem reappeared and I was not able to boot it normally. In most cases, the device freezes in Samsung GT-I9515 logo, it continues to restart or simply does not vibrate or power on.
When charging, I don't see anything such as the charging battery icon or the LED.
I realize that I was wrong to flash that PIT file, but is there anything I can do to make this device work properly?
Thank you in advance for your cooperation.
Noone?

Galaxy A40 infinite loop - impossible to turn on

Hi!
I have a problem with a galaxy a40 device, I flashed a stock ROM with Odin, everything went fine, green lights, PASS and all, but now the device just won't go pass the SM logo anymore. When I turn on, logo appears 2-3 secs I get a warning of the unlocked BL then logo comes back and after a second the phone restarts itself and the same goes on forever ( well about several hours, and after that it just shuts off somehow ). I cannot enter recovery mode or download mode at all. I keep pressing the combinations Power + Vol Down, Power + Vol Up, All three and every combinations I have just found on the internet so far. Odin doesnt recognize the phone, which is not a surprise since it won't start up. I have tried with adb but waiting for device is all I get.
How is it even possible that I cannot enter download mode at all? There was no problem with the physical keys, and the power still works, I cannot test the Vol buttons tho.
Has anyone ever had a problem like this? How can I come back from this? Is there a way to flash a ROM without download mode or turned off phone?
Thanks for any help!!
The download mode for this model is different from previous Samsung's :
IIRC, with the phone off, you need to hold VolumeUp and VolumeDown, then plug in the USB cable connected to a computer (you may need to press Power to power up the phone, I can't recall properly).
From there, you should be able to restore a stock ROM with Odin.
Let us know if it helped !

Here the same problem, have a40 in loop and never get rocgnized for computer, tryed many different cables, and installed a booring large amount of drivers software and nothing...
you need to power off device completely. let battery drain if you can't shut down. press and keep holding volume down + plug in usb cable for Odin3 (I doubt both?)

Generic answers, repeated 800 times why really need to waste a post with that? and that not was the problem:
1- For no usb recognition, is this phone bad design, in the back tap where is the battery in the samsung logo more or less if you push with fingers and charge is because the design of baterry is so crap and your usb port goes off when the under tap cable moves or just get little out of conection. If you can get working after push, usb on phone will do too.
