Galaxy S8 bootloop fix (ODIN, Smart Switch not working) - Samsung Galaxy S8 Questions and Answers

Hello everyone,
I know this is a topic that had already been widely discussed but none of the suggested fixes were able to solve my issue. I also was not able to post this into the recoveries forum thread as I have just made a new account and I do not have the permission to do so.
My galaxy s8 is now stuck in a bootloop on the Glalaxy S8 screen and it does not progress from there. I can access the download mode but that is about it. I am not sure how this happened as it was fine one night and then i put it in my pocket, and when I pulled it out the next morning, it was stuck in this bootloop.
I am overseas currently, and so unfortunately I am not covered by the local Samsung warranty, else I would have gone through them.
I have tried flashing the firmware which I downloaded from Sammobile, including the BL, AP, CP & CSC which has not worked. I tried using Smart Switch which does download and re-flash the software, but in both situations, my phone still remains bootlooped.
I am not sure if I am doing anything wrong in these steps. Please let me know if there are any other solutions I can try to get my phone working again.
Much appreciated!!!

Did I make jewellery out of my s7 edge? :S

I have the S7 Edge SM-G935F, which is the exynos version I believe.
It starting with unrooting, which boot looped my device. I have tried samsung kies firmware recovery but the download always stopped at a certain percentage saying an error was found in the dowloaded file. I tried to fix it by flashing what I believed was the stock bootloader with odin but that made my problem worse.
It turns on and shows a red coloured screen, and the voice assistant kicks in to babble but seems to not respond to touch at all. I think I can go into download mode, because I've seen a shop assistant get into it when I took it to see if they can fix it. Unfortunately It would cost 230 euros, which I cannot afford. And in case you are wondering, no I didn't buy the phone. I got it as a birthday gift, as I never owned a smartphone before that.
I loved trying out apps and tweaking the phone with root, but unfortunately I wasn't careful enough.
Is there any hope for me? Thanks in advance if anyone could help me out.
EDIT: Thank you to both replies! I did as you said and I downloaded the correct firmware. It seems the one I flashed before was actually incompatible. Everything works now thought, I lost all data but better than having no phone.

Go to sammobile.com, create an account & download the latest firmware for SM-G935F. Install Samsung Drivers on pc. Boot device into download mode. Extract the downloaded firmware and use odin to flash it.
In case you don't know there are 2 S7 phones, S7(930F) and S7 Edge(935F) and their firmware files are not exactly interchangeable.
I think you might flash s7 firmware on your s7e since red screen is the same symptoms when you flash S7flat kernel on S7 Edge. The fix is easy, just reflash again with the correct file.

Bricked AT&T GALAXY S6 EDGE PLUS

I was trying to root my at&t s6 edge+ using Odin. As soon as the process completed, my phone froze on Samsung screen. Then I tried wiping cache and data but nothing worked. I downloaded few stock ROM for Odin but flashing keeps on failing. I read in some thread that new Samsung devices do not support downgrading. I went and checked my current build number and found that to be G928AUCS4CPK1. However, the firmware I was trying to flash were older version.
Has anyone experienced similar issue before? The main problem here is I cannot find the exact build number anywhere. I spent a lot of time searching and finally decided to post here.
Your valuable suggestions will be greatly appreciated.
Thanks.
hey man, you flashed an older version of the firmware? even if it wasnt bricked, your phone is essentially useless now. the efs is gone, meaning you cant make phonecalls or connect to wifi at all. sorry; your phone is bricked. perm.
download mode dosen`t work ?if so the only thing you can try is to use samsung kies to restore your phone but don`t know if that works
I done something similar to my standard S6 Edge the only difference was i was able to start it up ok and i thought everything was ok until i realised i had no reception. I so happened to notice my imei number was gone. I had no back ups of the partition that saved this info so i totally bricked my phone.
I did however find a website that would be able to do a work around ( for a fee of course) for it however it does question your morals as its essentially illegal in alot of countries. I dont want to post anything on here so if you want any info send me a PM.
Exact same thing happened to me... went to AT&T repair center but they didn't have the 'K1' firmware..
anyhow managed to find the latest firmware (gsm-firmware.com)... cost me $4, but the phone is up and running... I only flashed the AP file.. also used Odin 3.12.5..

Samsung Galaxy Core Prime SM-G361F stucked on download mode

Hello.
I have big problem with flashing SM-G361F.
It has stucked on download mode after regular OTA update and i can`t do anything with phone anymore. Recovery isn`t working also. I have already try everything i have find on net to fix it,but with no luck. I try to flash it with all versions of ODIN, and try 5 different USB cables on a 3 different PC-s, and always with the same result.
All what I can "flash" is PIT file, everything other isn`t working. I have try sofar every repair firmware i have found,lot`s of kernels, recoverys, custom roms, etc, but with no luck at all.
Any ideas?
Thank you.
Hello and apologies for my absence.
It seems you are in quite a pickle here, but since you can access Download Mode and Odin, that's great.
What I should tell you is that you don't need separate BL, AP, CSC and CP files to flash the ROM, since it uses the older method of flashing (which is much easier and more logical).
Unfortunately, since I am unaware of your mobile's network and it's nationality, I cannot recommend a specific ROM.
There is quite a list at https://www.sammobile.com/firmwares/galaxy-core-prime-lte/SM-G361F/ for this specific type of phone.
You need to put in your country and carrier and choose the latest version of the firmware since I am unaware of your phone's carrier and your nationality.
Either you can provide me with your country and mobile carrier or register to download the firmware yourself if you prefer.
Hope you get it fixed!

EDIT:
TAKE YOUR IMEI NUMBER DOWN IMMEDIATELY!
I know most of us on the forums are nice folk, but posting your IMEI number is bad, since someone could use it and take calls and texts from it if you insert a SIM card, leading potentially to some bad things happening, for example someone using your phone's IMEI to take calls and texts while you are stuck with the bill!
Please! At least blur it out!
Thank you for your quick respond.
Unfortunaly i have already try all available rom from that link for my country and carrier, and it is always the same result.
I have the same issue with the G361F. Except mine always stays on the "samsung galaxy core prime" logo. I have tried around 15 Roms and always the same result.
I think i have the same problem:

Any news about that?

S8 SM-G950F - Unkown cause, possibly bricked!

Hi guys,
Phone: Samsung Galaxy S8 SM-G950F
I was given this phone by a friend of mine who attempted to install factory binary or something or rather.
He can not recall exactly what he attempted to do, however.... This is the condition it is in now..
I have no clue where to even begin with it.
Any and all help would be greatly appreciated.
Drew.
Blind bet is that freund is finished with this phone if doesn't go to download mode.
Your are need to download official firmware from Sammobile and flash it through odin .
First thing is to see if odin detects it in download mode.
Ive managed to get an almost bricked s8 at least alive and kicking a few days ago by reflashing *only* the AP file (stock 8.0 XSA from Sammobile) which at the very least got me around the locked bootloader issue. Its just killed the IMEI in it.
In a couple of days ill get another shot at restoring it to full funtionality but ive already replaced it anyway so its most likely only going to be used for DeX now.
Ive had no responses to my post so meh.
Which exact one did you use Funkymonkey..?
Thanks in advance.

Samsung Galaxy A5 2016 SM510F Only Download mode no booting

Hello, a friend of mine gived me an hard bricked phone.
As written in the title the phone is a Samsung galaxy A5 2016, SM510F.
Is not the first time I do things like that, but this phone is quite frustrating to work with.
I tried everything on this phone but the only thing that it does is the download mode.
It has no hardware problems, everything is working fine. The battery can't be removed.
I obviously tried to let it charge for long time. It does not even shows the battery icon while charging.
No boot, no logo.
I tried flashing 2 different version of the original ROM downloaded from SamMobile with Odin.
I tried an old and a new one.
I tried Flashing the Bootloader extracted from the ROM.
I tried flashing the 4 part ROM.
I tried flashing the PIT, since i suspected that my friend somehow cleard NAND while he was trying to flash the Root.
But out of this I get nothing. Odin gives a success but the phone only turned off and did not reboot.
I ask you if you have some different ideas, some similar experiences or some advices.
If you have some files please remember that I'm italian, so I need ITV.
I have no more ideas. Otherwise I will tell my friend to try to go to a samsung center.
Thanks.
You can try install custom recovery
