FRP Locked S8 G950U - Samsung Galaxy S8 Questions and Answers

I have a Galaxy S8 that is FRP locked.
The exact model and version is: 8.0.0/R16NW/G950USQS3CRE2
From what I understand this has the v3 bootloader and Oreo, correct?
I need some help getting this phone unlocked. Anyone care to lend a hand? I can use Odin and ADB just fine, I just need to find the correct files needed for the version I have.
Also, if I can actually get the correct files., can someone outline the steps needed to do this? I've been trying to unlock this thing for about three weeks and my brain is turned to mush with all the things I've tried.
Please don't send me PMs trying to get me to contact through other means.

Hey. Don't worry. Frp lock is a protection for your phone this occurs when your oem lock is on. To unlock it go into developer options and then tick the oem unlock option . But for now your phone locked all you can do it flash stock firmware using odin . That's the only way . I know the data ma be precious inside the phone but it be useless until phone in not booting . So ho and flash stock firmware for your device from sammobile.com
Thats all . I hope may this helps you and inform me as soon as possible.
Stay Blessed?
Sorry for bad english.

Yeah, flashing the firmware doesn't reset the FRP. Tried just AP, AP and BL, all five, doesn't matter. On first boot it requires the previous owner to log in. It's stored somewhere that's not touched by the flashing process somehow. Or it fails. After doing all five files on first boot it says it's installing something, gets into the 30% range, then says erasing for a bit and reboots.
Is there any way to do this?

There is no oem unlock on a U model. Need to study up a bit before advising.

flash a combination file factory reset from combo then flash legit bit 3 or higher firmware. The 30% failure after erasing is normal. 32% normally

Thanks for the reply. Is this what I need?

I've never done a combination file, so not sure what's involved.

Its test and diagnostic firmware released by Samsung. It is not a usable rom. You'll flash this. Factory reset from inside the settings menu. Then you can reflash official firmware. And you should be good to go unless this has been patched

So I went ahead and flashed the combination file in the first link and did a factory reset. Now when I try to flash the files I already have it fails. I'm assuming that's because I flashed a bit 5 combination firmware, and the stock files I have are not bit 5.
How do I know which firmware files I need? Do I need to do all files (BL, AP, CP, CSC) or just one? It's very hard to figure out what to do when everything I read is different.

Yea you need bit 5 files. Flash all 4. If you look at a firmware number. 5th dig from far end will be a 1-6 that's the current bit, anti rollback whatever you want to call it.

Thank you so much for the help. I'm getting closer.
I am currently downloading a file called G950USQU5DSC1. Should be bit 5. I'm pretty sure it's for Sprint, and this phone was originally Verizon. Will this be a problem? I'd very much prefer AT&T or T-Mobile, but Verizon might be OK if I'm locked to it.

verizon firmware is unlocked sim wise sprint firm probably wont work but also should setup based off of your sim card inserted.
dsc1 i believe is pie which is awesome on s8 you can change carrier also with the combination file pretty much as your doing with each personalized firmware to each carrier

I'm grabbing the file from this page: https://www.theandroidsoul.com/samsung-galaxy-s8-firmware/
How can I tell which carrier is which? I'd rather just flash the correct one off the bat. Looks like the only one on that page for the 950U that is Pie is the Sprint one. I don't have a SIM. Well, I could take the one out of my current phone temporarily if it'll help set it up correctly.
Is the process for switching carriers just flashing the CSC file? Or is it more involved.
EDIT: There is a CRK1 file that is U5 and Oreo. Pretty sure that is Verizon. Cancelled the other file and am downloading this one. Going to take a while, using my phone as it's faster than my home internet.

The CsC determines sales code and carrier setup. I use sammobile or updato.com they have all firmwares needed

Boom. It worked. Typing this on the S8. Even accepted my AT&T SIM and connected to data.
Flashed an 8.0 firmware, but it seems to be getting updates. Maybe it'll update automatically to 9.
Anyway, thanks again. Free S8 is nice.

that firmware is from sprint. something worth sharing is that all S8's designated for the US market are literally the exact same physically. You CAN flash whatever firmware you want for whatever carrier on a g950u. You will need a modified version of Odin to flash firmwares originally intended for a different phone tho. I had the FRP lock on my dads old S5 the other day, but i was able to get thru it with my gmail information oddly enough. Not sure why google thought that authenticating use on that device per my gmail account credentials was ok, but..... ok i guess.
Once you get the phone up and running, put a sim card from whatever provider you intend on using in the phone, if it asks you for an unlock code, then youll need to get one from the original carrier it was intended for or a third party paid site. AT&T has a sim unlock tool on their own site you can try.
Teh reason i mentioned that all the S8s intended for the USA are literally identical is because you can take a sprint S8 and use it on Verizon, AT&T, T-Mob blah blah provided youve flashed the correct firmware, which is either the U1 version or the bespoke firmware for that carrier

Very good info. Thanks.
When I first booted the phone after flashing I had put my StraightTalk AT&T SIM in and it connected right away. It also started downloading and installing system updates, all the way through the Android 9 upgrade and the August security update. Pretty cool. The only thing I see is after a reboot or power on a notification pops saying that a non-Verizon SIM is installed. But that notification can be dismissed, and as far as I can see doesn't recur until next boot. So easily ignored. And there's Verizon specific bloatware. Maybe I'll download AT&T and T-Mobile images just in case. I've been thinking about carrier hopping, as I have pretty poor AT&T coverage in my area, since with StraightTalk I can get a Verizon SIM added to my plan and take my AT&T one off pretty easily.
I haven't really used the phone much yet, as I'm waiting on a case, but I'm not sure I'm going to like the Samsung skin. I'm used to a very stock Android experience, as I've only really used Motorola phones and my current Nokia 6.1. I just like plain vanilla Android. But I'll give it a shot. Already installed Nova Launcher and F-Droid.

followed everything on this thread, uploaded 5 level firmware files just fine, but now i get a "system software not authorized by at&t.." message.. any help?

Need help asap please - SM-G935W8

So I was setting up my device yesterday and enabled fingerprint unlocking and choose a pattern unlock and written password as backup options.
When I restarted my phone, in order to unlock the phone it stated to use pattern unlock to protect fingerprint scanning after reboots (something of that nature).
Problem is for some reason I cannot figure out the pattern to unlock (I'm sure im using the one i set in place) and I cannot use my written password to unlock either, it's just by pattern.
So am I locked out of my phone and don't know what to do. I'm trying to do a factory reset to see if that'll work.
But I also flashed twrp and noticed that this model cannot be rooted so i left the custom recovery as it is. I do not want to swipe right to "allow modifications" as I heard if I do not install the right files it might be stuck in a continuous loop. So I clicked on Keep Read Only. When I try to wipe it keeps on telling me it's failed is it due to being in read only (I also don't see any of the contents on my internal storage)?
Should I flash the stock recovery with odin but I cannot find it for this model. Can someone point me in the right direction?

Installing BTU rom help

Hi Guys I was one of you for a long time then drifted to the darkside with apple. I am back but so much has changed and I want to ensure that I dont goose up.
I have a SM G935F S7 edge
I have contacted my provider and recieved sim unlock code. Placed alternative sim in phone and entered the code and it returned sim unlock. (its a pay as you go sim i used to unlock with no credit so I cant test I can make a call)
I am torn between rooting and not because of my banking app with Barclays, but on the advice of others I would like to try a stock samsung rom without all the bloatware.
I have sith super backup backed up my contacts apps call logs and sms messages and saved them to google drive.
So have I dont all i need before flashing and if so which stock rom can I use. do I simply use the most recent BTU from smmobile for my country or is there a better way to select the rom I should install.
Look forward to your answers but if anyone has Barclays app working on root let me know then I will just take the plunge I care not about the warranty as I have alternative insurance which wouldnt care.
Thanks again in advance
One of the reasons I haven't rooted is for the same reason as you. Barclays are a real pain in the arse to rooted customers. I have tried everything to get around this but nothing can. The only other option is logging in via the website but every so often this requries a card reader so it can be a pain in the arse.
Anyway, to answer your question, you seem to have covered anything. BTU is probably your best option if you would like stock samsung with less bloat. Although, I believe you will not receive any OTA updates and would have to update manually when updates become available.

BTU is UK unbranded.
Download this: https://www.sammobile.com/firmwares/download/116121/G935FXXU1BPLB_G935FBTU1BPK3_BTU/ this is the latest
Also download odin 3.11.1 the link is just below the details on the download page.
once everything has finished downloading, backup important data on your phone and put your phone into download mode, unzip the Rom file, there will be 5 files inside, delete CSC_HOME (you don't need it), Flash BL, CP, CSC and AP all with odin, but in odin settings, select Re-partition, F.reset time, Auto-Reboot, then start, the CSC file contains a PIT file which will wipe your phone.
Here is my thread on Sammobile confirming the flash: https://www.sammobile.com/forum/showthread.php?t=34984
I did the same with my S7 Edge to debrand it, I can confirm the Barclays app still works as its Samsung official software it doesn't trip knox, although I'm fed up now of waiting 6 months for android 7 I'm thinking of just going to a custom rom, i'll just use the browsers to goto Barclays.
The only way the Barclays app wont work is if you have ever flashed a custom recovery, rom, or rooted which all trip the knox counter to 0x1

Doesn't really matter to be honest, just means you loose a bit of space as the BTU firmware file is one of the smallest out of the lot due to the lack of bloatware, repartition would have given you this space as user storage, but its not much to be fair.

Still think I might redo it when finished. the reason being is I let samsung reinstall stuf where I feel I should just have loaded super backup on my device then restored that way.
Plus I stupidly said yes to microsoft stuff beacause I need outlook but I dont need all the other crap.

[Guide] How to Convert BACK to 100% Stock T-Mobile from 950U1 Firmware

Hi everyone,
If you've clicked on this thread you are probably just like me. You have a T-Mobile Galaxy S8 (950U) and wanted to try the unbranded/unlocked firmware. Maybe you thought it would SIM unlock your phone (Nope) or maybe you thought you'd like it but just don't. I was unable to find anyone who successfully reverted back to fully stock T-Mobile. My phone stayed XAA/XAA/TMB no matter what I did. Well, now I'm TMB/TMB/TMB and here to hopefully help you do the same.
I mostly followed this post: https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487. Here's the instructions:
1. Download Factory Binary, EngBoot, and the G950W firmware.
2. Turn off phone
3. Hold down on Bixby button + power + volume down
4. open Odin v3.12.7
5. add the Factory Binary to the AP section of Odin.
6. Plug your phone into your computer (NEEDS TO BE WINDOWS) with Odin open
7. Make sure your device is connected and recognized by Odin.
8. Click start.
9. One the phone reboots run the ADB command, adb reboot bootloader
10. Open PrinceComsy (modded) Odin and flash the EngBoot
11. Click start
12. Once the phone reboots type the command adb reboot bootloader
13. Put the HOME_CSC of the G950W firmware into the CSC part of Odin 3.12.7 (NOT PrinceComsy)
14. Click start
15. Open IME setting on Factory Binary
16. Type in *#243203855#
17. Select XAC
****NOTE ABOUT 15-17: A bunch of system processes kept saying they were force closing, but I just kept saying OK until I could successfully type the code into the dialer and select XAC. It worked, even with those processes supposedly failing.****
18. Click install
19. Wait for phone to reboot
20. Once it does open terminal and type in adb shell
21. Then type in echo "TMB" > /efs/imei/mps_code.dat
22. Type in exit into adb shell
23. Type in adb reboot bootloader
24. Flash the G950U T-Mobile firmware without Userdata. Also make sure to flash the non-home CSC.
25. Enjoy your reverted back to T-Mobile 100% stock phone.

Great work, bro
This was all mine. I did all of this. Why does nobody say anything about me doing it. It is in the EngBoot + Root thread. I mean really, thank the people that actually DO the work.

Agreed, I used your guide to help me get back to TMo version. You will find variation of your work here and there. But I agreed that OP should be credited.

Happy to give you credit man. I spent days asking on four or five threads if anyone had converted their T-Mobile S8 back to 100% stock. I found no one. One guy mentioned he got his Verizon S8 back to stock.
I found the carrier switch thread ...which gave great instructions, but didn't tell you anything about where to get these files. So I searched around to get the files and spent a good two hours trying and failing until it worked. I figured a thread with not only the instructions, but also all the files you need...would be helpful.
I'm on XDA a few times a year when a new phone comes out. I could literally care less about "credit." However, I can tell you do...and I am thankful for your instructions. I would honestly have no problem with me deleting this thread, having you copy the text, and then you can post the same thing again only with your name as the thread maker. Let me know.

Can you copy the instructions (and the files I gathered in this thread) and make your own post? I will delete this if you do. Because it does no one any good to have the comments on here being about people wanting credit. Why don't you just re-post this under your username?
All I care about is helping people.

Hi everyone,
If you've clicked on this thread you are probably just like me. You have a T-Mobile Galaxy S8 (950U) and wanted to try the unbranded/unlocked firmware. Maybe you thought it would SIM unlock your phone (Nope) or maybe you thought you'd like it but just don't. I was unable to find anyone who successfully reverted back to fully stock T-Mobile. My phone stayed XAA/XAA/TMB no matter what I did. Well, now I'm TMB/TMB/TMB and here to hopefully help you do the same.
I mostly followed this post: https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487. Here's the instructions:
1. Download Factory Binary, EngBoot, and the G950W firmware.
2. Turn off phone
3. Hold down on Bixby button + power + volume down
4. open Odin v3.12.7
5. add the Factory Binary to the AP section of Odin.
6. Plug your phone into your computer (NEEDS TO BE WINDOWS) with Odin open
7. Make sure your device is connected and recognized by Odin.
8. Click start.
9. One the phone reboots run the ADB command, adb reboot bootloader
10. Open PrinceComsy (modded) Odin and flash the EngBoot
11. Click start
12. Once the phone reboots type the command adb reboot bootloader
13. Put the HOME_CSC of the G950W firmware into the CSC part of Odin 3.12.7 (NOT PrinceComsy)
14. Click start
15. Open IME setting on Factory Binary
16. Type in *#243203855#
17. Select XAC
****NOTE ABOUT 15-17: A bunch of system processes kept saying they were force closing, but I just kept saying OK until I could successfully type the code into the dialer and select XAC. It worked, even with those processes supposedly failing.****
18. Click install
19. Wait for phone to reboot
20. Once it does open terminal and type in adb shell
21. Then type in echo "TMB" > /efs/imei/mps_code.dat
22. Type in exit into adb shell
23. Type in adb reboot bootloader
24. Flash the G950U T-Mobile firmware without Userdata. Also make sure to flash the non-home CSC.
25. Enjoy your reverted back to T-Mobile 100% stock phone.

Where would I check if I'm TMB/TMB/TMB? I went from XAA firmware back to stock TMB firmware using official Odin 3.12.7 and all seems fine. I don't see any issues at all but I do wanna confirm everything is good to go.

If you follow all the steps to change the CSC to TMB, then at the very end flash the unlocked G950U1 firmware, does the phone still identify as TMobile? And would you be able to get the TMobile updates (like the 6/7 update)?

Nope, the systems are different. The updates are also different. The G950U1 ones come from samsung the others come from TMobile.

Gotcha. Thanks for your replies. Main reason I'm worried about staying on the unlocked firmware is Samsung's horrible reputation for updates last time around. I'm afraid we won't get the updates on this firmware until 6 months after the carrier versions.
Can I use this ROM and instructions to switch from Verizon S8 to Tmobile S8 Rom?
Thanks

Help
When I try to flash the home_csc in the CSC spot odin then click 'start' odin says Fail!SHA256 is invalid.
I thought if we just flashed 950u1 firmware we could just flash straight back to the tmobile stock firmware in the same method.
So this whole thread is about 950U1, which is the S8, what about S8+? I have a T-Mobile S8+, flashed the unlocked version firmware, wanted to go back, but this instruction only deals with 950U1, what about 955U1?
Ok, i can say if you just flashed the 950u1 or 955u1 firmware with modified odin. All you have to do is flash the tmobile firmware with official odin and then do a data reset from the bootloader menu.
I was able to go right back to official tmobile firmware and get OTA updates.

Try a different download...Sprint firmware flashed fine on unlocked version
I was able to get it to flash onto my unlocked by enabling only UMS/PATCH in Odin, not USERDATA, and after I had let the unlocked firmware provision the device with a T-Mobile SIM.
Also, I have the latest T-Mobile firmware if someone can get me somewhere to upload it. Downloaded it using Smart Switch this morning. N950USQU1AQI5

I will be picking up the unlocked model today and have T-Mobile. I assume you are in the same boat? Have the unlocked model, and then flashed the tmobile firmware?
As for uploading, if you have a google drive account, you should be able to upload it there and then make the file public. That or MEGA should work just fine.
Do you have a short guide of how you flashed the tmobile firmware?

I tried making a thread with the download link to the new firmware but I don't have enough posts to do so.
Here's a Google Drive link: https://drive.google.com/open?id=0B2hgX_SwidPzcEhIWDJ1ZGRRbjQ
In terms of flashing, I put my T-Mobile SIM into the device with unlocked firmware and let it provision (it, oddly, took about a half hour before mine did, but it should have been instant). After it reboots after provisioning I boot into download mode. I used Prince's Odin and in the ini file I changed UMS/PATCH=0 to UMS/PATCH=1. Start Odin, connect phone (in download mode) select the 5 files with the appropriate button but select USERDATA with the UMS button. Start, wait, reboot, viola.

how do you extract the USERDATA file from the carrier files and is it in the AP or CP

I m trying to understand each step:
Insert the TMO sim into the unlocked Note8 (bought from Samsung).
Let the phone runs its course until it reboots (could take some time).
Boot the phone into the download mode.
Open Prince's Odin and change UMS/PATCH=0 to UMS/PATCH=1. Do you make the change in the Odin3.ini?
After the change, Start Odin and connect the phone which is already in the download mode.
Select the 5 files with the appropriate buttons (which files and which buttons?)
Select USERDATA with the UMS button (is that the USM/PATCH=1?).
Start the process and the phone runs its course until it finishes.
Am I correct? Is there a chance you can post the screenshots?
I have the unlocked one from Samsung and want to use it with Tmobile firmware to take advantage of all its features.
TIA
I’ll pay someone $20 via PayPal if they can help me swap Verizon firmware on the Note 8 to T-Mobile or Unlocked; I would prefer T-Mobile. Seriously, $20 if someone can successfully help me.

Sprint A205U Flash Firmware To MetroPCS

I have a Sprint A20 that hasnt been sim activated and unable to locate OEM unlock. I have tried to flash the MetroPCS firmware on to this phone but no matter what i flash, the Sprint firmware is still installed after reboot. I receive no errors during flashing and everything succeeds, but no sign of the flashed firmware upon reboot. Any Ideas? Thank you.

You can't unlock the bootloader of A205U, that's why you can't see then OEM Unlock on dev. options.

Im not looking to root though and i dont even want to use any custom rom or any of that. When i flash metropcs successfully, i just want it to stick when the phone boots, instead of Sprint firmware magically re appearing. If its a successful flash with official firmware, then why wont the Sprint firmware go away / be overwritten, especially when it is a successful flash. Maybe i am wrong, but from what i remember, even when bootloader is locked, you are still allowed to flash official firmware, or am i wrong?
