Unable to revert to stock rom - Samsung Galaxy S8 Questions and Answers

I have an unlocked Galaxy S8. I flashed it with the stock Sprint rom to get Sprint visual voicemail and wifi calling features. Doing so changed the model of my phone from SM-G950U1 to SM-G950U. Now, I am unable to flash back to the stock rom because Odin says the model number doesn't match. What can I do to revert back to the stock rom for the unlocked S8 with region code XAA? All help is appreciated.

I recently reverted back from T-Mobile firmware to unlocked S8 as it used to be. You need to use custom Odin, not the regular one.
Do the section where is says "Flashing Unlocked Firmware"

Same happend to me, sadly the walkthrough linked above does not work for my SM-G950F (Exynos, cz version)
Mobile had TWRP+LineageOS 17.1 installed, is currently in Odin download mode and both version of odin (PrinceComsy 3.12 and Samsung's 3.14) look like in the picture below, they always get stuck like this.

[Q] Need some information about I9502 (Samsung galaxy S4 Dual)

I had purchased an I9502 through olx.in, last week.
Second hand.
Due to rare users, there is no dedicated thread on XDA for my device
Now, many questions arises.
I had updated to official lollipop (5.0.1), by SAMMOBILE's official ROM. After upgrading, my second SIM cant connect to network. So I revert back it to KK (4.4.2). Still the problem persists !!!!! . I couldn't use it as a dual sim phone Is PDA and CSC version is important while flashing? or we could install any PDA/CSC rom version on samsung phones? I don't know the original ROM so, I had downloaded all firmwares available at sammobile and tested. only 2 of them managed to register my SIM(first) on network. Is it a hardware issue? or by a wrong ROM ? anyway now my mobile admitted at hospital and specialized doctors have been studying his disease
Is there anyone using dual SIM without any errors?
The PDA and CSC are vital to ensure you get the right regional variant for your device. The only exception is if the phone is unlocked for use on another carrier, in which case you can use a ROM from any region. Where you have the dual SIM version however, you only have one region available to you, but with multiple Android versions. The firmware here is the latest for your device. Do a factory reset before flashing through Odin.
I am totally disappointed.
My technician said that it had lost IMEI !

What will I do?
Is there anyway to recover its IMEI?
I had followed all guidelines available through search.
But, I couldn't...
Please help me on this....
Flash just the modem through Odin. You can extract it from the firmware download. Sometimes the modem needs to be flashed twice before everything functions correctly.
Other than that, I'm not aware of anything else software-wise that can be done. You'll need to take the phone to Samsung themselves and have them look at it.

Return SPH-L720 to stock FW

Good Day everyone, I am looking for some directions to the correct section. I live in Australia and have a Sprint SPH-L720 S4. I would like to take the phone back to stock S4 firmware, as the phone works awkwardly in Australia. Any help please? Cheers

Follow the first 6 steps in the instructions section of my ROM thread (linked below). Substitute OD2 for whatever firmware version you desire to flash. Just know that you can't go backwards, as in you can't flash older firmware than what you are on.

Thank you I will give it a go. I bought this phone from a guy, not knowing it was a US Sprint phone.

Depends on which one you choose. OD2, OH1, and OK3 are all Lollipop firmware.

SM-T377A -> Tmobiles T337T rom?

Can I flash the Tmobile rom for the SM-T377A (AT&T) over the top with Odin and have it work out ok? Im assuming they are the same exact hardware. Thanks
smt377t
i have the tmobile version of this tablet.
do u know if i can root my device?
can u recoomend a good rom?
Unfortunately it will not work that way when they write the programs for these devices they write them as stated sm-T377t is for t-mobile, and sm-T377A is specifically for at&t
SM-T377A Samsung AT&T Marshmallow or Nouget Stock ROM
Hey everyone,
I successfully rooted my LG V-20 and I really enjoy how nicely my phone works now. Smoort, responsive and everything is editable (within reason of course).. So, I have set my sights on my tablet.
Samsung E Tab
(Model: SM-T377A)
AT&T varient
Android 6.01 (Marshmallow)
- I have tried every possible combination of flashing the tablet with Odin. (all 3.x versions)
- This includes trying the COMBO package, the 4 part flash with or without using the PIT file and I also tried just the 'boot.img' falsh (with PIT and without PIT)
- If I include the PIT file then it very dependably fails via the PIT error.
- I have also done the Factory Reset and made sure I used the proper drivers, matched the Build number with the flash file that I am trying to use. (ATT_T337AU.....)
- I have also Unlocked the Bootloader via the Developer settings within Android andUSB debugging (per usual)
- Below is what I have been getting plus/minus a a couple of variable details

The only thing I haven't tried is using either Marshmallow or Nougat. I thought that Lollipop or Kit-kat would work (or it was worth trying)
With all of that said, does someone have either the silver bullet suggestion on what I need to do to or have a good copy of the AT&T E-Tab series ROM???
Specifically: 6.01 or 7.01 ROM for SM-T377A ROM
It would make me so happy, THANK YOU,
Davis

Odin failing at sboot.bin could mean you are flashing wrong firmware for your phone or your trying to flash older version firmware than what is on your phone(bootloader version). Have you tried latest firmware g950fxxu4cri5.
Yes,I think it's the last one for my phone,actually using RENOVATE_ICE_G95X-13.4,but now I see that it was locked to a Portuguese operator, MEO and I'm trying to flash the unlocked operator rom, could it be that?

Could be. I don't use carrier branded firmware and if I can help it never will there's enough crap just with Google and Samsung. If it does fail with unbranded (carrier) firmware then flash the carrier version. Either way you will more than likely need the latest firmware version to return to stock rom.

S8, download mode shows Knox 0x0 but S-health and other related app say rooted

Hello everybody,
I am totally new so please forgive me if I ask something stupid.
So I got this phone, S8. In Download Mode, it shows Knox is not tripped (0x0) but my S-health and Samsung Pay doesn not work. And I am sitting at android 7 and cannot upgrade.
Pics attached below.
I know nothing about rooting or flashing so a little more details would be super great. Thank you guys.

Go in the recovery what version does it say at the top. Also what model is the device its written on the back next to imei number.
Looks like you are on carrier locked device with locked bootloader and rooted rom.
Your solution is to flash same version of stock firmware.

Hi Vcek,
It is S8, SM-950U. Unlock carrier. Android 7 version, G950USQU2BQK5
So in the end, is it rooted or none-rooted phone? The Knox 0x0 confused me alot.
I did some google and someone says sth about flashing with Odin, and flash all of the options such as Bootloader, AP, CP, CSC and so.
Then my question is,
1. Will flashing with Odin using the firmware I download updato.com (could not download from SamMobile) trip the Knox?
2. By saying stock firmware, do you mean "official" firmware or else? Like I can use a firmware for T-Mobile, android 9 (Pie) or I have to use a T-Mobile, android 7 version?
3. The firmware I got from updato.com is for AP flashing, so for other options like CP, CSC, where can I download the official files?
4. I should not flash bootloader, should I? Since it will trip Knox?
5. Is there any better sites than updato.com and SamMobile? One is so freaking slow and the other is not downloadable.
Thank a lot for helping me!
Hi all,
The problem was solved. I just flashed all of the options with a stock room using Odin.
