re-flashing stock OS onto Samsung Galaxy S8 - Samsung Galaxy S8 Questions and Answers

Model: SM-G950F
Build Number: PPR1.180610.011.G850FXXUCDUD1
So I recently flashed /e/ OS (a fork of Lineage if anyone is unfamiliar). Unfortunately, /e/ was giving my phone problems, and also Verizon doesn't work with it, so I decided to flash Android 9 Pie back onto it. After hunting down the version of my phone's firmware (I live in the US but my phone is a refurbished phone from the UK), I downloaded it, plugged the BL, AP, CP, and HOME_CSC into PrinceComsy Odin. In TWRP I formatted the storage and all that, and then I flashed it using Odin. I got the green "Pass!" and the <OSM> All threads completed. (succeed 1 / failed 0) messages, but when I went to TWRP's reboot screen, it said there was no OS.
Are there settings I am missing or something? I have the G850FXXUCDUD1 firmware, I tried combinations of just flashing the AP and CSC, just AP, AP BL and CSC, so on and so forth, but no dice.
I've scoured the internet for help but nothing I have tried has solved the issue, so I figured I'd try here. Any help literally at all would be appreciated. If you need more information on the device or what I did in specific I would be happy to oblige. Thank you in advance!
EDIT: I've only gotten into software hacking relatively recently, and XDA-Developers even more so. As you can tell by the age of my account, this is the first time I've ever posted or anything haha. I tend to lurk on tech forums. Anyhoo that is all
EDIT 2: I downloaded Odin 3.13.3 and am trying that. Thus far it either fails or gets stuck on SetupConnection
EDIT 3: I downloaded a different zip from a different source for my phone. It succeeded in Odin, put the default recovery back on my phone, but now it is stuck on the samsung logo when trying to boot.

Noob - Rooted Samsung Note 4 randomly turning on and off

Hi ,
I recently rooted my Samsung Note 4 (running Lolly Pop 5.1.1) and about 5 days later it started turning on and off by itself. I noticed it only started doing it when I went to update the apps. Often when it self restarts it will get into a stuck loop, where it gets to the load screen, freezes, and re-starts again. The only method to get it to work again is to leave it with the battery out for 30 + mins and it always seems to right itself - except.. I thought it would be a smart idea to do a factory reset. Now it keeps getting stuck in the loop on the load screen of optimizing apps, and since this is a bit a of a lengthy process, it always resets itself now.
What can I do? Any help from experienced individuals appreciated!
Really don't want to brick a 4 month old $899 phone.
Thanks in advance people
Make a clean rom installation; download the latest firmware for your variant, clean dalvick, cache, system, and data. Then, flash the firmware through ODIN. After that, root with a custom kernel. If you have an N910C I recommed you this kernel:

Hi Bryan,
Samsung Kies will not let me do a latest firmware install, it just keeps popping up 'device not supported' when I try to do a software reinstall and upgrade via Kies on my laptop
Is there anyway to do this on the fly?
Thanks for your help

Visit SamMobile and register, then search the appropriate firmware for your phone variant.
Example: My phone is an Exynos-Note 4 (N910C) and my operator is Tigo Colombia which in SamMobile appears COL. You just have to register, search the firmware for your phone and flash it using ODIN 3.10. (ODIN is a program you use to install firmwares in Samsung phones) There are lots of tutorials for flashing, it is quite simple.

Won't flash after XAC

I got a s8 VZW a couple weeks ago and flashed XAC firmware on it everything went smooth, now I can't flash anything anymore. I place all the files in the correct place in Odin (tried different versions and different firmwares like G950U1 and TMB) but when it goes into file analysis, setup connection, it goes All threads completed (successful 0/failed 1). I can't figure whats going on. Help would be very much appreciated.

Galaxy S8 Installing System Update Loop (VZW)

I recently was given a phone from a friend. He told me that his phone worked fine until he powered it on one morning and it was stuck in a loop. I do not know exactly what firmware version it is on but I have downloaded a number of versions from Sammobile. I have attempted to use Odin to flash the stock files onto the phone but it has failed every single time. I have tried to use different versions of Odin aswell. I have also spent countless hours trying to find the solution through other XDA posts but nothing I have found so far has worked. Going into further detail with Odin, I have posted a picture of my settings. The first 2 attempts just end with "<OSM> All threads completed. (succeed 0 / failed 1)." When I try a 3rd time, it reaches the initializing process but Odin closes after a few minutes of saying that. The screen on the phone doesn't seem to change at all either. I have installed firmware before on other phones, but this phone just doesn't seem to work.
I am willing to give more information or try other things if anyone has the ability to assist me. Thanks All!

Samsung Galaxy Note 4 System software not authorized by ATT has been found

Got a huge problem with a AT&T phone Samsung Galaxy Note 4. Got it from an ebay handler. It was supposed to be rooted. However, after installing Magisk software (https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445) I got the message "System software not authorized by ATT has been found on your phone". Whenever I turn it on, I see it and the phone doesn't start. Since more than 6 months have passed, the ebay handler declined to help. I called AT&T, but since the phone is rooted, they declined to repair it even after I offered to pay. There are some solutions I found online for other samsung galaxy models, but none which works for note 4.
Tried to restore the system to the factory version, it said that restoration has been successful, but I still see the AT&T message.
I followed the instructions to unbrick the phone by reinstalling the firmware - the method that should work for all phones (not just note 3) https://www.youtube.com/watch?v=bv_NCfYemEs with the firmware for SM-N910A , however no matter how long I waited, the download process never completed.
Any suggestions?
Thanks!

Grab latest firmware for N910A from here
https://androidfilehost.com/?fid=745425885120746376
Make sure samsung usb drivers are properly installed on your pc before you begin.
STEPS
1 Download odin and Firmware and Extract it.
2 open odin tool and upload firmware in AP slot.
Odin can take up to 5 minutes to upload firmware so be patient
3 put phone into download mode
4 connect phone via usb cable and hit start.
5 After FLASH once odin shows pass boot into stock recovery by pressing 3 button combo volume up+ home+ power.
6 in recovery do wipe cache+ wipe data factory reset.
7 reboot system and wait 10 to 5 minutes.
DONE
Trex888 method should be good, however you may need to find the pit file and flash it before odin back to stock. I bought my note 4 already rooted, but the person that did it used the wrong files to flash. Mine was good but buggy. The rom flashed was not verizon, and it locked out some partitions including the one where the imei was held. I had to fix the partitions with the pit file then reflash to a different rom and i was good to go after that.
Thanks
Thanks for the reply! Great! I will try that - very hopeful

You dont need dedicated pit file unless your device has errors such as "dm verity verification failed" or failed to mount cache/efs etc etc.
If stock rom flashing by odin went smoothly no require for repartition or pit file.
Playing with pit file and repartition is extremely dangerous and can cause device to hard brick so i would not recommend unless some serious issues with device.
Fyi every samsung stock firmware has pit file in the system image by default and odin take advantage of it by it self during flashing.
Have a nice day.

in my case, whoever flashed my phone flashed an f file instead of the v file. It lost the imei and would not recognize a sim card. I tried flashing original firmware but the imei was still gone. The ONLY thing that saved mine was to find the correct pit file and flash it before firmware. It fixed my issue and got me back up and running. every original fw flash for me failed until I flashed just the pit. I cannot explain why the original fw included in the odin package would NOT work. Hence the statement of "you may need to" instead of "you will have to".

Root attempt fail, "kernel is not Seandroid" bootloop.

Bought a Galaxy S7 Edge today from a coworker, SM-G935F, Verizon variant (as far as I know. She bought it brand new and used it on Verizon.) First thing I tried to do was root it using this method -- https://theunlockr.com/root-samsung-galaxy-s7-s7-edge/
(basically used Odin to flash Samsung_G935x_QC_Rooted_BOOT.TAR)
Got a "Pass!" message in Odin, rebooted the phone.
Was greeted with a pretty red-colored message on the top left, "kernel is not Seandroid" followed by a continuous bootloop. Would automatically shut off on its own, etc. Had to boot into recovery to actually power it off. (Still stock recovery, by the way)
Anyway. Googled the error, didn't seem like a big deal with so many results and "Solved" also being prominant. Tried to revert back to the stock firmware and got this in Odin's log:
<ID:0/003> Re-Partition operation failed.
Came across another post suggesting to un-tick the "re-partition" option in Odin, which it already was/is. Now I'm kind of lost on what to do. Came across one thread suggesting that the firmware on my device doesn't match the one that I downloaded which.. I have no idea how to check that given I'm unable to even boot the device. I do recall seeing 2017 briefly when scrolling through the build/kernel section, possibly December 2017 if my memory serves me correctly.
Another thread suggested something about flashing a .pit file.
Does anyone know I how I can get this back up and running? Preferably rooted?
Thanks much in advance!
