I have a phone I am fixing for a friend, so I don't have a complete accurate history of what happened, so please bare with me.
Basically, you put the battery in and it boots right to download mode (Factory Mode), no power button required. I can then reboot it using the power, hold down the Vol-Down button and then I am prompted if I want to enter D/L mode, in which you can use Vol-Down to cancel and it boots like normal.
I have tried the following, nothing fixes it!
Factory Wipe
Root using CF-Auto Root
Every Key Combination Possible on Boot
Odin Stock Install
Kies Upgrade (just stalls on that)
It was not rooted when I got it, and now it is. I haven't installed any recovery yet, but am willing too. It has possible water damage, so it ain't going back to the store anytime soon. I can't even get USB Debugging to appear that it is connected, nor will ADB recognize it. But the USB is working and read/writing.
This isn't my first time working with this sort of stuff, I am just at my wits end, plus I'm a Sony/HTC/LG person, so if there is something I am missing with this wonderful(ly crappy) bootloader, let me know.
Thanks in advance!

If you can hold the vol-down and home button when you boot it up and get into Odin mode you should be about to flash the stock MD5 for your phone. Stock Canadian Odin files here:
http://forum.xda-developers.com/showthread.php?t=2269304
Also make sure to use the lastest version of Odin, 3.07 I believe. After you are done flashing with Odin you will have to boot into Recovery (vol-up when booting) and do a factory reset. This has always fixed any boot problems with my phone.

So did you go into settings, more, developer mode to check usb/debug?
USB debugging isn't required to flash the Odin MD5. One thing I did notice is that you should boot into Odin download mode before connecting your USB cable. I was having issues with Odin not detecting my phone and waiting to connect the USB cable solved that.

Duh...
I was referring going to adb fastboot
see the thing is that flashing did work fine, it just didn't fix the problem. I guess in Samsung terms I am stuck in Odin download mode when turning the phone on. This is why I wanted to see of I could push some standard reboot command via adb to see of it would "jig" it into place, but no matter what I try it always boots into download mode first.
and yes, I did turn on usb debugging

Could you have bent pins maybe where you plug it in? Its doing exactly what a jig would do..

Nothing is wrong with the pins, USB is working fine and can be used in any other mode. I got ADB finally, I guess it was just not playing nice with me before. However, still anything I try the bloody thing still insists on booting first into download mode.
Just an update, it is still booting into download mode, tried a couple different stocks and still no good result. Anyone suggest any of the options in Odin might help work? Like F Reset Time or Phone EFS Clear?

I have seen this elsewhere, one guy suggested, using Keis, and it took him 2-3 times to get the stock to stick.
As far as checking those items in odin, could brick the phone. he also said, he got nowhere using odin in this situation.
Have you tried maybe flashing a recovery via odin? could be the recovery is corrupt.
what does this mean: in which you can use Vol-Down to cancel and it boots like normal. <<< Can you boot to the OS?
I can imagine your frustration here...good luck.
I did try Kies and it would keep getting stuck at 10% (I let it sit overnight) so I had no luck with that...

Yes, I have gone from stock recovery to CMW and back to Stock and still nothing. As for you other question, yes, I can boot into Android. The downside is I can't turn the phone off unless the battery is pulled out. This is why I bought an HTC One and not an S4 lol .. thank god this isn't my phone, but it is frustrating because of all the things I've tried to do to fix it.
Hi,
Have a weird situation, but try as much as I may, I'm unable to resolve it.
My phone is rooted (international D802) and was running fine. Had a screen issue and got it replaced at the service center but their system identified my phone as a rooted device, and a couple of days later the problems started.
The issues I'm facing right now:
1. The phone doesn't charge when switched on, at all.
2. The phone doesn't reboot either.. not instantly anyways. If powered off, or rebooted, the phone doesn't turn back on, it just goes dead. It does boot again though if tried after a couple of hrs.
3. The phone charges when its off (shows no light or indicator though, like its bricked)
4. Cannot go into either recovery or download mode. Coz the phone doesn't boot when restarted or when i try to reboot into recovery.
5. When it does magically start after a few hrs (upon long pressing the power button), even if I try to go into download or recovery via the vol keys, it just boots to android.
6. The phone is recognized properly as LG G2 under windows and all the drivers install too.
7. The phone isn't recognized under Linux... tried both Ubuntu and Knoppix.
Travelling out of the country in a few days, really need to sort this out.
Any and all help/suggestions will be greatly appreciated.
Thanks in advance
Somebody... Anybody? :'(
When your phone rebooted I would recommend you firstly to activate USB Debugging in the developer settings. You said your device is rooted? So try to install the Auto Rec recovery here
https://www.androidfilehost.com/?w=files&flid=13763 - but make sure you are on Kitkat. Now, install the app normal and let the app install all things. After installation, the app asks you to reboot to recovery, now press reboot to recovery.
Maybe you have luck and the phone reboots to TWRP. In TWRP you can go to Reboot and then Reboot to Download mode.
Now (if all worked) you can flash the stock rom .kdz file of the d802 via the FlashTool 2014.
Hope you have luck, please keep me up to date if everything worked.
Yours, Flo
Good luck!!
Thanks a lot for the response Flo, but the problem is that i never got around to updating to a Kitkat rom... the rom i was never got updated and I was kinda happy with how things were working so didn't jump on to any other rom.
Anything I can do in my current situation?

Hello guys,
I guess I won't be the only one having this issue. My phone went dead suddenly, and doesn't boot. It only give a circle with a lightning bolt but not charging, is it a battery issue ?
At the same time, I can only go to download mode, no recovery, and I can flash via Odin, with success, but it doesn't boot up still.
This is driving me crazy and I am not sure whether it's a hardware or software issue !!!
Anyone having any thoughts on this ?
Thank you.
Turn your phone off. Put it on the charger. Leave it alone for at least 1/3 of the day. I've been using Android for a long time. This usually happens to my Androids, at least once in their lifetime. It should be good to go afterwards.
PS: Make sure your charger works and don't touch the phone. Let it get a good 8hr charge w/o touching a button.
Let me know if this works for you.

HEY brother.
my case is a bit weird
i bought my s8 running nougat used it for 2 days and it was all good , so i received the Oreo update and updated it using the over the air when I received connected to wifi.
my phone started to reboot randomly even for 30 times per day , i tried several things like wiping cashe and the only solution that reduced the problem was uninstalling my installed apps. basically normal apps like facebook , whatsapp , spotify ,and even stock apps like calculator and music player.
today as usual I woke up picked up my phone and it started rebooting so i uninstalled some apps but it kept rebooting.
sometimes it reboots and get stuck at GALAXAY s8 boot screen [ not samsung flickering screen ] and all i had to do to overcome the boot loop is pressing and holding volume down and power button.
but one time it got stuck and boot looped once and for all. I tried to press volume down and power button to make it reboot again and overcome the bootloop but it rebooted and got stuck at the bootloop.
I tried to access recovery but i couldn't access it.
I can access download mode only.
my phone switches on itself when it is plugged in to charge , i can't turn it off completely to charge it while off.
I reflashed stock firmware and it succeeded using odin but the bootloop is still there.
please help me with my problem SIR.
and thank you really a tons.
sincerely,
Zack.
Did anyone manage to solve this? My phone has started exhibiting the same behavior.
Unable to power on the phone unless it's plugged into the charger, but if plugged in just keep boot looping to the Samsung logo.
I've tried re flashing the latest stock firmware, but this hasn't made any difference.
sounds like a typical case of the battery beginning to fail
Flash twrp and a custom rom... Only solution but go to YouTube and check how to flash twrp s8 oreo? Must watch
Flash back to stock, leave the phone charged until 100% then use the stock recovery or flash twrp and wipe cache and dalvik
Thanks all for the suggestions.
I've tried to flash twrp but I get the error "Custom Binary(RECOVERY) Blocked by FRP Lock".
I've flashed the stock firmware multiple times successfully via Odin v3.1.13.1 (G950FXXU2CRF7) but this doesn't make any difference.
I still can't boot up the phone. The only thing I can do on the phone is have it plugged in and go into download mode.
I can't boot into recovery.
If I leave it plugged in it will power on, vibrate, boot loop to the Samsung logo all day. (It does not show the charging circle)
Could this be a worse case scenario and be a hardware issue? Don't want to give up hope yet, since I can still flash a firmware with Odin.

It varies depending on what firmware I try to flash it acts differently. All firmwares I try to flash will take a while in "flash analysis" and then to "setup connection" it takes so much time. After wait some time it fails.
I can send you some pictures if needed. When I get home I will.try again and send you the error.
This is what one error looked like trying to flash G955USQK2_Stock_recovery_BoxWares.tar.md5
This is the error.

even after a new download of the 4 files?
Hi. Browsed for ages and always come here for answers.
Here's my problem.
2x S8s. SM-950f.
Updated to most recent software through software update. Both phones were glitchy and crashing and just generally irritating after.
Factory data reset etc. This did not resolve the problems, also led to one of them having issues with FRP (annoying)
Used Odin to try and flash the latest firmware (from sammobile, UK BTU) after flashing both, they reset and powered on. Got stuck at the S8 screen.
Restarted then both were at the "an error occurred during update" screen.
Managed to get back to download screen. Re checked the software and model numbers, even that the bootloader was the correct version etc. All was fine.
Connected to Odin, shows that it is connected, but nothing happens when clicking start.
Now after attempting that, both phones will not power on.
(One will when placed on the wireless charger, but just sticks at S8 screen) and download mode or reset screen can not be accessed. So, not exactly happy. And totally out of ideas
Any suggestions, beyond taking it to a shop to see if anyone can help.
yes .....dont tuch the phones for 24 hours let the battery die ...it will...connect to pc and then try download mode....u may need to press combination for like 1 minute to get to download mode....flash twrp reboot directly into it when odin says successfully .....wipe system data ....dont turn on phone download any custom rom flash and enjoy.....it will trip knox but worth than getting a new board....
Okay, will give that a try.
TWRP?
TWRP install
https://dl.twrp.me/dreamlte/twrp-3.2.3-0-dreamlte.img.tar.html: Download link for twrp SM-G950F (dreamlte)
Just said, wait until your device powers off due battery insufficience. Plug cable and hold at the same moment vol(down)+bixby+power. Then press vol(up) at the warning screen to proceed to odin mode. Let it charging a while like 1 h. Then unplug it and plug it to your pc. In Odin select ap the previous downloaded file. Take your mobile in your hand. With one hand, prepare your fingers to vol(up)+bixby and with the other hand start the flashibg process. Be careful, and take your hand directly from the mouse if you clicked start in odin, and position your one finger to power button, but dont click. If odin start pass, press immidiately the buttons (vol(up)+bixby+power) and let it to start into recovery. If you arrived to recovery, reply to us if not search for help!!!
Good luck

Okay, downloaded TWRP, can get phone calls nected to Odin but when I extract TWRP it doesn't give a valid file type.
Am I being dumb.
No files appear that Odin will recognise.
Also just shows as "recovery" no .tar or anything
Ignore above. Corrupted download.
Sorted.

Not sure what stage your at and maybe some more useless ideas
1. Trying to flash twrp is kinda of useless if you can't get into your system need oem unlock for that.
2. Have you tried taking out Sim card and SD card and reboot.
3. If you can at least boot try smart switch as it has a emergency recovery option.
4. Trying rebooting in safe mode.
All been attempted
I was going along ok until I made the fatal error of transferring the Magisk patched file to PC via MTP instead of taking the time to re-learn adb, which must have corrupted it. Thus predictably Odin hung and I am in trouble.
Where I am stuck is being unable to turn the phone off to come back in download mode to start over with stock firmware. I have been unable to find any secret button presses, and the battery doesn't seem to want to die leaving me with an $800 paperweight.
I did search around for this first and didn't find any real answers. Has anyone found an effective solution to this problem? Thanks.

Thank you, but the PC won't recognize the device. What does happen is the emergency recorevy screen tries to come up. I tried starting in download mode with bixby+vol down then USB. I did get the battery low enough where I don't get the teal screen of death anymore, perhaps it is too low for USB to work? What I was hoping for was the charging animation but no luck. Surely this is just a software problem and there is a way out.

Did you try getting into recovery and perform a data factory reset and then see what happens?
Just load the stock firmware BL, Ap, cp and home csc into Odin if you see emergency teal screen. The emergency screen will start loading
Black screen ....Perhaps your battery is dead?
Thank you all for the replies. I had let the battery get low in a misguided attempt (based on advice elsewhere) to get it to shut off. I had to let it charge a while for it to wake up enough for PC to see it. Then I was able to flash in Emergency Recovery mode.
Thank you for the help.

Glad you got your device up and running ?
Maybe someone can help me. I seemed to have borked my phone. I kept getting "Google is Stopping" with no way to fix it, so I tried reflashing my firmware in odin. After I loaded all the files and hit start, I realized I didn't untick auto reboot, so I tried aborting the installation and ended up with screen (I've had it before and got out of it by still flashing in Odin, but now, if I try to reflash firmware while in this screen, it's stuck on SYSTEM in odin.
Any help appreciated!
Try this
That is where I got stuck. Are you trying to flash stock or patched firmware? I had to start over with stock as I copied the patched via MTP instead of adb and it got corrupted.
I think what I did was unplug and reset Odin. Wait for screen to turn off, then make sure it is at least 80% charged. Then Bixby + Vol Down + plug in and you will go back to this screen. Then I was able to flash stock. I had to go so far as to re-lock bootloader and flash stock again since my "OEM Unlocking" was not just greyed out but missing. Since then I've had no time to try again, but at least I have a working phone.
This is my anecdotal procedure, can't say if it is the right or best one.
Hi All,
I was trying to flash the latest firmware for my device (G9750ZCU2ASG4) and during the odin process, my computer restarted which failed the update halfway through. I rebooted the computer, tried again, and it was trying to establish a connection for a really long time, so I disconnected my phone from the USB port on my computer, and held Power and Volume Down to try and force reboot the phone. I was going to try and go back into download mode to restart the process. My phone mentioned something about needing to do an emergency recovery, but I continued to hold down the power and volume down keys and then everything went black on the phone.
I've tried multiple USB cords, all of the button commands known for the device, and have even tried to perform the emergency mode recovery on my device, but it seems like it's in some sort of locked state; What I mean is the phone is stuck on a black screen. I can't "boot" into recovery or into download mode. The phone doesn't even vibrate when I hold the power button or power and down to try and force reboot it. Odin doesn't recognize the phone when I plug it into the computer nor does the device manager on my windows computer.
Does anyone have any experience with this sort of issue or any idea of what else I can do to try and get into download mode to flash my firmware again? All help, suggestions, or comments regarding this are much appreciated.
Sounds like the battery is dead
Hi Dude, I am struggling with the same problem, read this post and it came to me, had to come back and give you the solution.
Press bixby+volume down, IMMEDIATELY after the screen goes off, hold volume up and down while connecting the USB cable super fast.
You have got like 10ms to do it
Otherwise it just goes back to the AVB FAIL screen
Ran into this issue, none of the above worked for me.
This is how I resolved:
1) Placed phone on wireless charging mat and let it boot to emergency recovery screen
2) Load TWRP into AP slot of Odin and leave the window open on your computer ready to flash
3) Connect phone to computer whilst it's on the mat and press start in Odin as soon as your device appears
It may fail a few times but if your quick you can install TWRP.
4) Now boot into recovery and let your phone charge to a reasonable level (above 20%)
5) Boot into Download mode and flash your desired rim via Odin
