I have a galaxy S8 SM-G950U from T-Mobile while trying to install stock firmware on my device, my device received an error. Currently my device does not boot into safemode, recovery, or the os. It only boots into download mode. I tried to do an Emergency software recovery but smart switch does not support my device. I need help. I do not know what to do. My device’s warranty is still valid.

You can use the latest Odin 3.13 and download your firmware from sammobile.com and load it from download mode

Hi, I am using P600 (note 10.1 2014 Wifi) XAR one
Yesterday I was trying to install magisk all day, but failed all
When I rooted device and instaled TWRP, in TWRP it made error number 1 and it says something like turn to stock boot, so I tried to reinstall stock firmware via Odin, but it didn’t change anything.
I guess it’s a problem with boot.img or the autoroot method I used.
So I tried to use fastboot to install TWRP without rooting, but this time it didn’t boot into bootloader from fastboot, it just restarted the tablet all the time.
So I tried to manually reboot into the download mode, but fastboot didn’t recognize the device then.
When I did it, I turnned on the USB debugging with no mistake since it’s just samsung.
So I booted into recovery mode(It can go into recovery mode without problem)
Then tried option “reboot to boorloader” and it just restarts the tablet again.
I guess something corrupted boot.img or bootloader somehow, while I was rooting or something.
Can I get factory boot.img and solve it? Or when I install stock firmware via Odin does it also fix boot.img and boot loader?
I tried to install stock firmwares and factory reset several times. It didn’t help anything. It did unroot or turn the recovery to stock recovery, but couldn’t get into bootloader.
Can anyone please help me or give me advice to solve this problem?

Hi there, I hope you guys can help me. Here is the information I have, and thank you so much in advance for your help. Really hope someone will be able to help my stupid self. Haha.
SM-G925F
1.Your bootloader status if applicable - UNLOCKED
2. Rom name with complete baseband/date/version - NEMESIS NOUGAT STABLE S7E PORT V3.1 -
3. Kernel name - Linux 3.10.x
4. Any Mods you are using - None
5.If you are using Custom Rom, your flashing style i.e dirty/clean or you wiped anything else in specific - Flashed Nemesis after flashing another rom that used superSU, then attempted to restore superSU while still using the same rom. I believe this caused a bootloop and I factory wiped the phone to attempt to resolve the bootloop, which has been unsuccessful.
6. If you used any guide, link to the guide - N/A
7. Root status - ROOTED
8. Your exact problem - When attempting to power up the device, stuck in the flashing samsung logo screen. I am able to access both TWRP recovery screen and download screen, however TWRP does not recognise .tar.md5 files, so it seems I am unable to flash a recovery.
9. Any method you tried that failed - Factory wiping the device
10.Any other detail you think would be necessary - I believe am unable to use ODIN as I am using a Macbook, however I am attempting to use it via Parellel. I can still transfer zips to the sd card using the TWRP recovery. The download screen reads:
ODIN MODE
PRODUCT NAME: SM-G925
CURRENT BINARY: CUSTOM
SYSTEM STATUS: CUSTOM
REACTIVATION LOCK: OFF
SECURE DOWNLOAD: ENABLED
KNOX WARRANTY VOID: 1 (0x030c)
RP SWREV: B:5 K:2 S:2

First thing... if it's just stuck on the glowing Samsung logo then it's not a bootloop. It can take a while to boot so leave it about 20 minutes.
TWRP won't recognise tar.md5 files as it doesn't flash them. It flashes .zips. Odin is the one to flash tar.md5.
TWRP is the recovery, so you can't flash a recovery through a recovery (twrp)
What I would try from here... power on the phone and leave it on the Samsung logo for a while and it should boot. If it doesn't then just reflash nemesis ROM through twrp and start again.
I tried to root my g9650 s9+, I finished everything with TWRP recovery and now everytime the phone tries to boot it just gives me the Security Error this device has been locked because of unauthorized software. I cant access recovery mode. I am planning on flashing the stock rom with Odin, is this the right thing to do? Please help.

Solved it by flashing stock fw, do I have to wait a week again to attempt root again?
trying to flash TWRP on my S5 but when trying to enter recovery i get "could not do normal boot", "Secure download : Enabled", "UDC start"
looking online people seem to have problems with having Odin not recognise the device or stuck on the bootloading page but my issue is reserved to just not being able to flash the recovery.
I'am still able to flash CF Auto Root and the stock firmware via Odin. also tried to check if my bootloader is unlocked but does not show up as a fastbootable device (i already had twrp 3.0.1 and lineage os 14.1 so i would assume it already is unlocked)
sorry for missing any needed information
Hi , try to flash latest twrp recovery with Odin.
https://eu.dl.twrp.me/klte/twrp-3.2.3-0-klte.img.tar.html
If that doesn't help you flash this stock recovery with Odin , if that doesn't work download latest stock firmware for your device and Region and extract just recovery.img and make it as tar or tar.md5 to be flashable with odin .

Hello,
I have been trying to install Android 11 on my phone (Galaxy S9 SM-G960U1) for a while. I have realized that in order to flash new firmware onto my phone, it must be signed or the bootloader won't accept it. When I flash non-signed custom firmware, Odin returns an error about authorization.
Only OEMs/Carriers sign Stock ROMs / OTAs provided by them. ODIN works with Stock ROMs only.
To flash a Custom ROM you need TWRP or similar.

I cannot use TWRP without rooting my phone, which will take some time. I will use the Extreme Syndicate method (https://forum.xda-developers.com/ga...pment/root-t4041815/post81608559#post81608559) to root my phone, then install TWRP.
