[HELP] S8 Stuck at boot Screen - Samsung Galaxy S8 Questions and Answers

Hey guys,
I really need your help. I have done an update of my twrp. My phone is rooted.
Now after it the phone stucks at the boot logo "Samsung Galaxy S8 powered by Android".
The hotkey combination for booting to Recovery does not work; nothing happens. The hotkey combination for download mode works.
I tried applying TWRP via Odin; nothing changed. What can I do? I don't want to lose all data

EDIT:
Problem solved: TWRP Version twrp-3.1.1-2-dreamlte.img.tar seems to be broken. DOwngraded via odin and it works again!

flash stock rom through odin then flash twrp. yes you will lose your data this is why it is advisable to keep a backup.

[Q]Rogers Galaxy S4 stuck at boot logo

After flashing some ROM, I am having trouble because the phone is stuck in Samsung Galaxy IV logo.
First couple times I was able to boot to twrp and do a format, wipe, flash, then davik wipe. The problem is that I was able to restart and set up and update etc but if i restart the phone, it would stuck at boot logo.
So I flashed it again and installed GooManager and installed twrp again, tried to restart and it would just stuck at Samsung boot logo, I can't even get into recovery mode.
I tried using Odin and flash cwm but it would not boot into recovery mode.
Does anyone have any suggestions?
I'll try to flash it with stock ROM with ODIN going into download mode, but somehow I don't think that will work.
I'm using Canadian Rogers Galaxy S4 SGH-I337M
Please let me know if there is anything I can do
Boot to download mode (volume down+ home during boot) and Odin to stock MDJ firmware would be my suggestion. Give it a boot and then factory reset. If hangs on first boot, go into recovery (volume up+ home during boot) and factory reset via recovery. After phone boots install triangle away, reset counter, and then do the OTA update.
Finally got around to updating to the MG1 firmware last night and found that Odin directly to MG1 did not update the modem (baseband) and also left me with no Wi-Fi. The above steps applied the new modem and did not cause any Wi-Fi issues.
After update, to root just use the CF auto root for Canadian models with Odin then goo manager for custom recovery (twrp).

Unable to flash stock rom, please help!

Hello to you all,
I've downloaded and flashed the original samsung lolipop rom for my SM-T535, but something went wrong and it gets stuck at boot (samsung logo) and once or twice it boots up but freezes when I'm making the initial setup (google account etc.) and restarts and stops at boot indefinitely.
Now I want to go back to kitkat and I've downloaded the correct firmware for my region (Spain), but I've been unable to flash it. Odin tries flashing it (almost completing the process), but it says FAIL at the end. I try installing lolipop again (and Odin succeeds flashing it), still stuck at boot, but I can access recovery mode. I then make the factory reset and wipe cash, and try flashing kitkat again, but still Fail.
I would really appreciate some help, if anybody has an idea what could the problem be.
One other thing, when ODIN fails I try accessing recovery mode, but it says Firmware upgrade encountered an issue, please select recovery mode in Kies and try again.
Can you flash a custom ROM?

[SOLVED] Can not install TWRP [#failed to open recovery] Help!

[ORIGINAL POST] - solution further down - (TLDR do not reboot into system after flashing recovery)
Hi,
I'm trying to install TWRP but when i've flashed PDA via ODIN and reboot into recovery, this is what i get. [see images] https://imgur.com/a/zfdvs
TWRP file from TWRP website: 'twrp-3.2.1-0-dream2lte.img.tar' for Samsung Galaxy S8+ (Exynos) (dream2lte)
As this did not work i tried to flash new BL and CP and then i retried to install TWRP, no luck.
Can you please help me! Thanks!
I also tried flashing TWRP (another version just to be safe) via heimdall, but that didnt work either. The enitire prosess is fine, but when i reboot into recovery i still get to the same page. [see images above]
[SOLUTION]
*Do not* boot into system after flashing recovery (TWRP), instead, make sure to boot directly into recovery.
Apparently Samsung Reinstalls recovery when you boot into system after flashing TWRP (or any other recovery for that matter). I do not know if it's like this for all Samsung devices or only the S8, but that's the way it is.

I had the same problem and found instructions to press volume down + bixby + power and then start the Odin load. The load went fine but my phone locked up at the Samsung Logo screen. I tried getting back to the download mode but the screen went black. Now the phone will not power on at all. Exceedingly frustrating.
I've spent 2 hours trying to work out what did I do wrong (checking hashes, odin version, etc) and the simple solution was to boot into recovery right away after flashing via Odin. Thanks!

I've followed different procedures but basically use ODIN to push TWRP to my SP-580. After that, the tablet reboots. I disconnect the cable and power the tablet down. I then hold VOLUME DOWN and VOLUME UP and connect the cable again. But instead of going into recovery mode, it just shows me the percent charged dial. I can get no further than that and have done that at least 15 times. HELP???? Thank you!!

Cant flash anything other than twrp on galaxy s8 and phone wont start

so i accidentally destroyed my efs partition on my Samsung and last baseband and all that in the process of trying to fix that i seem to have broken the bootloader or something so the phone just flashes on the samsung logo, when i try to flash stock firmware or anything other than twrp the flash fails and the phone shows this error: "an error has occurred while updating the device software. Use emergency function in the smart switch pc software." the phone isn't reconised in the smart switch software though so i cant try to fix it through that. im really not sure what to do at this point, does anyone have any ideas?
Update: i managed to find the latest firmware to flash (CRGB) however my phone gets stuck on the flashing samsung logo and idk what to do now. also my efs partition is broken is there a way i can fix that? (i dont have a backup)

[Help] Not rebooting after successful flashing (Odin)

Hi,
I have a Samsung J5 Prime (SG570M) that is stuck in download mode. I flashed the stock rom with Odin (both last version) and when the flashing ends, it says 'successful' in Odin, but when the phone reboots it doesn't boot up, the screen remains black. The samsung logo doesn't even appear. Any suggestion what could it be or what should I do? I have done this a few times and followed all steps, and already tried changing PC, USB port and cables. I don't know what else to do or what I'm doing wrong.
Any help would be awesome, thanks in advance!
Are you able to enter recovery mode and wipe the cache?
Thanks again for answering
No, I'm not able to enter recovery neither. Tried every possible button combination :/
