How to unbrick my S8+ stuck at Galaxy S8+ logo? - Samsung Galaxy S8 Questions and Answers

I tried to root my phone today but after reboot, it got stuck in the boot screen which says "Samsung Galaxy 8+". I can only go to the download mode. I tried downloading the stock firmware and tried to flash it using Odin but the flash always fails to give a Fail! (DeviceInfo) error.
I don't know what to do. I am afraid the phone is not charging as well, it the battery dries out my phone will be dead. What should I do?

Did you try and root the new AQG5 base? Flashing TWRP or CF Auto root will fail if you do so. If this is the case then follow the guide @Nameless provided https://forum.xda-developers.com/galaxy-s8/help/stuck-bootloop-flashing-aqg5-fix-t3636857 and throw him a thanks.
If you didn't do that and Odin still continues to fail when flashing stock you should give Smart Switch a try and go for an emergency recovery. You will need your device model number and S/N code ready. http://www.samsung.com/dk/smart-switch/

bootloader problem on s6edge+

hey guys im sorry if i post this on the wrong section but i followed this tutorial: droidviews(dot)com/root-galaxy-s6-and-s6-edge-on-android-6-0-1-marshmallow-update/ to root my s6 edge+ and it went black... after some research i found out the tutorial wasnt for my device(SM-G2928F) so i flashed it with cf-autoroot and then it boot looped for like an hour. I downloaded the original greek firmware from sammobile but it brings me up this error: SECURE CHECK FAIL : (BOOTLOADER).. any help?
UPDATE: changed the port and run Odin as admin now it says: SECURE CHECK FAIL : (RADIO) Odin log: pastebin(dot)com/4w1943HF
UPDATE: now when I exit recovery mode it doesnt start and tells me: An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.(I can still go into recovery mode)
Let me check you have flashed a firmware not for your device with odin or just a zip? First I would try flashing the most recent firmware you can find for your device with odin, some bootloaders can't be downgraded. If that doesn't work then the emergency firmware recovery will work, I've used kies emergency firmware a few times.
Hopefully someone with your device will point you in the right direction if you are stuck
I flashed a firmware not for my device but I found a solution on another XDA post thank you

Please help!!!!!!

Today i was trying to install the Android Marshmallow 6.0.1 on my Galaxy S5 Snapdragon via Odin, i downloaded the firmware from Sammobile, i verified that the phone model was exactly the same as named on the firmware, i place the .md5 file in the AP slot and everything was ready to go! (The phone was already plugged and in Bootloader mode, and drivers were up to date) then when finishing the flash Odin FAILS to complete the flash and the phone is left with nothing than the Download mode, i panic and try to access recovery mode but realize that there´s no recovery....I proceed to install the recovery.tar into my phone and it works, i start the phone and Samsung logo comes up, finally it loads and does al the process after you flash a Samsung phone.
Everything works just fine!...except for one thing, THERE´S NO RECOVERY!!!. The phone works perfectly but when i try to enter recovery mode, it sends me to Odin mode as it displays a message saying that failed to boot into recovery.
Please help me i don´t know what to do.
Thanks!
Just flash a custom recovery like twrp or cwm
Already did...same problem, recovery won't boot

You need to flash a pit file to complete the install correctly.

My Galaxy S5 appears to be unflashable/unrootable, any advice?

Hi,
I recently got me a Galaxy S5 (SM-G900F) and the first thing i wanted to do was installing CM13 as I always do with my new phones. However, when i followed te steps on CM wiki using Heimdall to flash TWRP the blue bar of the downlaod mode increases a small bit, then stops and in the command promt it says something about error with finding PIT. After trying this for three times i decided to go with Odin, which I do prefer anyways.
I tried flashing TWRP , the blue bar is filling to 100% but then on the little screen where Odin usually states FAIL! or PASS! it just says RESET! and my phone is restarting. Shortly after it restarded you can see the RESET! turning to PASS!, but when I tried checking in TWRP is installed, it wasn't. I tried it again and then Odin suddenly says FAIL! After restarting my phone it says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again". I couldnt even enter download mode anymore till I tried if getting out the battery would work. I could enter download mode again and flashed the same TWRP on my phone again, and aigain it says RESET! but after that my phone worked again. I tried flashing with another version of Odin and TWRP but same thing happened - First run it said RESET!, second run FAIL!.
I thought maybe rooting the device and installing TWRP via their app afterwards could do the trick. So i tried flashing Autoroot with Odin but it made my phone showing a screen with Samsung logo and in the upper left corner something about recovery mode, seemed to be a loop/freeze. So i took out the battery again and flashed TWRP and that solved the problem again. At last I tried rooting by using TowelRoot but it says the service is not available for my device, even though S5 is listed as a supported device.
I really have no idea what to do anymore, would be very grateful if someone could come up with a solution.
BTW: Is it possible to flash CM13 without using custom recovery by using stock recovery?

RESET! is basically the same thing as PASS! What version of TWRP are you installing? The keis screen you got is the same as download mode. Why are you using heimdal? your idea to go with Odin was a good one. Anyways, download TWRP 3.0.2 (not 3.0.2-1 or 3.0.2-2 as they are buggy) and flash it in Odin, reboot to recovery and install the ROM you like, of course following its specific install instructions. No, you cant install a custom rom with stock recovery
Thanks for your answer, meanwhile i managed to fix this problem. Had to flash the latest Firmware because twrp (could just install the oldest version otherwise I had no option to boot into recovery at all) said no OS installed. After rooting via Odin worked like it's supposed to.
Why did I use Heimdall? Because I wanted to stick to CM-wikis instruction and they used Heimdall.
