flash stock firmware.
go to sammobile.com
Search for grand 2 firmware
then download it.
The firmware must base on your country.
after that flash using odin.
after complete. Remove battery then insert it again.
go to recovery
wipe everything
then reboot system
wait about 10 minutes
congrats your phone is normal again

Solution to your problem:
You will need to download the NK1 version of kitkat 4.4.2 stock firmware.
1) install samsung kies or samsung usb drivers so that your PC will detect your phone.
2) Switchoff your phone first and put it in download mode by pressing volume down and home button and power button at the same time.
3) connect your phone to your PC through the usb cable and start odin. (The com port turns blue in odin which means phone is detected).
4) In odin, check the "Nand erase all" in the checkbox and then click on "AP" buttion and select the "G7102DDUBNK1_G7102ODDBNK1_G7102DDUBNK1_HOME.tar" file.
5) Click the start button and wait for 5 mins till the OS is installed.
6) After installation, on your phone it might show 'memory damaged' and 'erase memory'. Don't worry, nothing is damaged or serious, just click to reset and everything will be fine.
7) Done!
I have provided the NK1 version link to you from my google drive account:

(Please hit thanks if I helped you)

Thanks guys
Problem solved and it is working now :fingers-crossed:

I have this same problem and I downloaded the above file and followed the instructions accordingly, after flashing it is still stuck at REBOOTING TO RECOVERY for about one hour now.I guessing it might be related to hardware.

Which firmware were you on before the first boot loop? Flash that firmware, and don't forget to pull the battery afterwards.
(Don't hit thanks, hit the phone on a pillow/bed of you think its hardware related).

Now it wont even go into recovery mode or download mode. Help Me plz
Thanks In Advance.

So nothing at all happens when you press the power button with or without volume keys? If so, it is highly unlikely that you will be able to revive the phone, unfortunately.

Follow this awesome tutorial by @usman_fareed

SoftBrick - stuck in recovery with LDU, please help!

Hey guys,
So recently I got a SM-G928X Live Demo Unit. I just read that flashing G928F firmware is completely fine and so I did aaaaand well, I am stuck in recover. Forgot to flash a custom recovery, also the phone has Factory Reset Protection so I am here with:
Android Recovery
MMB29K.G928FXXU2BPB6
samsung/zenbltexx/zenlte
6.0.1/MMB29K/G928FXXU2BPB6
user/release-keys
volume up/down and power
____________________
then goes normal recovery options
and at the bottom of the screen, there's
Supported API: 3
dm-verity verification failed...
Need to check DRK first...
Anyway I can't get to download mode, cant wipe data, cant flash from ADB/SD Card. When connected to PC no software recognises the device so yeah, that's a great situation to be in, right?
So if any of you have any idea how to make this thingy work again, I'm up for anything.
Thanks

Hey, how comes you can not get into download mode? In case; do you know how to get into DL mode with the button combination?

Thing is there is this FRP thing and since I flashed a stock ROM it somehow blocks it from reseting the phone and even if I try to boot to download mode thru the button comb or thru the recovery, it just resets the phone and then boots to recovery immediately. Also this thing is preventing me from flashing anything from the SD card or ADB.

The guys were avoiding this issue by flashing the firmware. Since you can't boot into DL mode, that's odd. Maybe smart switch(or whatever it's name) helps. As far as i remember this lock is related with ''OEM Unlock'' in Settings » Developer options. Also there were some tricks around which you should research it at xda or youtube. Good luck.

I had no problem getting into DL mode but then I flashed the stock firmaware for G928F because I found here on XDA that it is completely fine flashing it onto G928X and since then it just boots to recovery and everything else just doesnt work. Pitty. Will try the USB JIG thing and will see..

hi

sorrry for bad english

Went to sleep, phone died, now stuck in a bootloop, can't enter recovery and etc.

Stock 7.0 AT&T model, I went to sleep, forgot to plug in phone. It died in the middle of the night, and the phone refuses to boot past the s7 edge splash screen and restarts every 10-15 seconds. It also will not enter recovery mode and says "Recovery booting..." I can make it enter download mode but I have attempted almost everything I have found and I either get a binary issue or it will successfully flash but then nothing will happen and it will continue to be in this bootloop. I actually brought it to a samsung "representative" at Best buy today and she said it wasn't recognizing the phone at first then it did, and she flashed something that she didn't say what it was and then it still didn't work. She then told me to send it in to samsung but since my glass is cracked (2nd day I had it too...) they try to say that i'm at fault. I just want to know how to fix this, I haven't had my phone in 5 days, I don't care about my data cause it's all already backed up online! Any help would be greatly appreciated.

Have you tried using samsung smart switch?

use samsung smart switch emergency software recovery initialization which is in the right up corner in "more". if its gonna be stuck and installing the software then connect your phone to a charger, hold volume down and power button and turn it off, this way the phone should stay turned off. then go to download mode and install s7 edge firmware from sammobile through odin

****, I forgot to mention, yes I have tried smart switch and every time I input the model number and S/N, it just closes out. Based on my research, that means initialisation isn't possible.

you'll need quick hand play
push volume down boton and power at the same time when the phone restars quick push the download mod conmbinaison and flash a stock at&t firmware you can download throught sammobile.com site;*,
edit : download the firmware throught this post: https://forum.xda-developers.com/att-s7-edge/how-to/firmware-att-s7-edge-g935a-official-t3412312
another edit lol: don't forget to unzip downloaded files
tell me if it works

Recently, I have seen many phones with bootloop problems and, at the end, the sim card was the one to blame.
I know it's silly but have you tried booting it without the sim card and micro sd?

I just actually successfully flashed SM-G935U firmware but to no avail it is still in this bootloop. I am about to just replace the screen and send into samsung ffs

Bricked S8s after software update.

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
memreb

Still trying to get them on. Powered on to download mode but only for a couple of seconds and switched off again.

i have the same issue with my s8 but when i boot in download mode the screen goes black but if i press volupe up it connect to odin with black screen you shoud give it a try

Will try that

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.
Now when flashing TWRP is gets to a fail due to
"Complete (write) fail

Hi you should try flashing official firmware

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
