Stuck on logo bootloop with no ability to flash TWRP nor downgrading - Samsung Galaxy S8 Questions and Answers

Hello guys,
here I am on the Galaxy S8 bootloop caused by flashing following firmware using Odin 3.14:
G950FXXSBDUA3 FIRMWARE.
After that I got bootloop on Samsung Galaxy S8 logo. I can't downgrade to previous version, as Samsung blocks that and I can't flash TWRP neither (when trying to do so I get "Only official released binaries are allowed to be flashed (RECOVERY)" ; I've forgotten to tick "OEM Unlocking").
So now I'm stuck at the moment where I don't really know what to do. Have I bricked it completely or is there any way to recover?
Thanks in advance for answering.
Cheers.
UPDATE: I just solved the problem. The solution was to flash the stock ROM again, but this time with the .pit file and tick the Nand erase and Re-Partition. After that it booted normally. Hope this will help some fellows with similar problem.

Look for instructions regarding soft brick, you'll just have to reflash via odin.

Flashing a N900A firmware in one N9005 is SUPER WRONG WRONG WRONG. Give a look here select one firmware good for your device and flash it via ODIN.

Rooting Samsung Galaxy J1

Hello, I would like to ask for advice rooting this phone (J100H). I've already tried this http://forum.xda-developers.com/android/development/rom-gennxt-prerooted-stock-t3126368, but got stuck in the boot loop and flashed a stock rom back. Would flashing the TWRP recovery help? Or do I need to flash a new bootloader? Doing the "oem unlock"? Thanks for any help.

SM-N910F Won't boot

Hi,
My SM-N910F wont boot. I have tried to flash a stock rom through Odin, and the flash is successful but when the phone boots up it just says "System UI has stopped" with a black screen.
I messed it up by flashing both modem and bootloader wrongly, then wanting to reset it by flashing stock firmware, but it won't work.
Edit:
I have flashed twrp and managed to factory reset, and it boots now. But now I have another issue, it restarts every 30 seconds, can't even get past set-up.
Edit2:
I have fixed it. I flashed the right modem and a bootloader update and it no longer restarts.
Would appreciate any help.
Thanks.

Galaxy A510F bricked

Hi all,
I bricked my phone installing nougat and after i formatted all. Now my phone can start in download mode only or loops on Boot logo.
Ca anyone help me to fix it? How can I find the right OEM firmware?
Thanks.
Hi. What do you mean by formatted all? If you formatted system your os is gone and phone won't boot.
Check updato for firmware fownload and flash with Odin.

From Recovery i clicked on all wipe functions. My phone is empty now. I flashed a PIT file and a bootloader but I got error flashing CSC and other.
Can you help me to find a full backup to restart my phone?
Originally it was brand tim but It'n not important for me.

You got twrp recovery? If you do, you probably wiped system partition too.
You don't need to flash pit, bootloader etc. You can just flash any custom rom to get it booted again.
Otherwise you'll have to download firmware to flash in odin. You probably need one starting with FXXU3 if you was updated to latest MM version, or N.
I wiped all. Can you guide me to download right file?

Bricked S7 Edge

Hello guys,
After stock OTA update phone started to randomly reboot and sometimes got stuck in bootloop.
I Flashed stock ROM over ODIN 3.14 ,got stuck at S7 logo,then i flashed TWRP and tried to flash like 10 roms with no succes,tried to reflash Stock rom,sometimes it goes to SAMSUNG logo but bootloops there.
My device is SM-G935F t-mobile version,twrp is crashing randomly while installing custom roms,tried lineage and got boot loop there,i maybe messed up when i went in TWRP and formated all to ext4.
This is stock rom i used https://www.sammobile.com/samsung/g...e/SM-G935F/CRO/download/G935FXXS7ETA7/315446/
i marked BL,AP,CP,CSC and picked corresponding files,I tried to flash older TWRP but still same problems,and also when i flash stock rom i get to blue erasing screen where it freezes,seems to me like there is no fastboot or smth.
I am trying to fix this for 3 days,any help is welcome,sorry for my bad english and thank you in advance.
Make sure you are using odin 3.13. Then you will be able to flash without problems:fingers-crossed:
