ENG Boot + Root

Thread on how to root S8! https://forum.xda-developers.com/galaxy-s8/development/samsung-galaxy-s8-root-snapdragon-t365930
Here is the Eng Boot for the SM-G950U. I did not get this, @unitz0mbie posted it. I am just posting it here. I will write a tutorial to root with this after it is done. We should have root at some point.
G950U1 firmware is the US firmware. It has the CSC info of each carrier but does NOT have any of the bloat or boot logos. For T-Mobile it has WiFi Calling and VoLTE. Verizon texting works with data and WiFi calling. All those carrier features work. AND It changes depending on the SIM card in your phone. So you don't need to keep flashing firmwares.
Thanks to @Rushstrike for going through everything with me for carrier changes.

we still need to get root for the S8. We have permissive SELinux status but still cant get a system mount. We have some people working on it currently. We are also waiting for another kernel from JUSMEJOSE.

Why? The eng boots that 3 or more ppl posted are the same ones we've had this whole time lol..
But to let you and everyone else know again none of them have root access at all.. all they have is permissive and that is it.. the s7 root bat does nothing, does not work

Let me get this straight. Root for Snapdragon in a couple days? I thought we were still waiting for stuff..?

[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.

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.

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.

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.

Help Me Convert 950U to AT&T 950A Please

OK I see there are a few threads on this but would someone please point me to the correct post to convert the unlocked US S8 to the AT&T version so I can get VOLTE and wifi calling? TIA for your help!

I have the same phone.
But what is so special about volte?

1st only works with other AT&T users with VOLTE capable devices but the audio is very strangely clear. For me this is about my entire family, plus I want wifi calling

Umm I have 950U that I Preordered direct from Samsung as an AT&T phone. I don't think there is an S8 950A model. I have VoLTE and wifi calling.

All model numbers are 950U, but to get to the at&t specific firmware, follow directions here:

Yes my mistake, I'm stuck in the past where every AT&T version is the A. I found the AT&T firmware for the 950U on SamMobile (G950U1UEU1AQE3_G950U1OYM1AQE3_ATT.zip) and was thinking I would need the CSC from that firmware but it seems not, Anyway thanks for the link and I'll give it a shot.

That's not att firmware that's unlocked us firmware since it's compatible with all major us carriers. I have that software version on my Factory unlocked US model S8.

Wow that post is all over the place. Can any kind soul that has an US unlocked and set it up as an AT&T device can help set me strait please? I'm thinking I need to flash the Engboot (never did this in ODIN so I don't what block it is?) and then Launch IMEI factory dialer and put in code ( *#243203855#). Not sure how to do this either unless they mean the phone's dialer app. Thank you sooo much for your help!

Follow the directions in the link I posted step by step... That's what I did and it worked to change mine from a Cricket phone to an AT&T phone.

I'm using an S8 unlocked version on AT&T postpaid account and I would not use AT&T's Firmware it's all full of junk apps that are not Useful at all.The S8 without all that blot where is much snappier lt is fantastic everywhere I go I even get LTE+

so I need every step for an unlocked as would be a locked phone?

You could try flashing the userdata section from an att firmware, some have said that worked too.

OK so I need all these steps at the bottom, still doesn't click to me why I need Canadian CSC to get AT&T features but ok. Can I get help with the following steps, Thanks,
Step 1. Download Factory Binary, (is this my factory unlocked ROM on SamMobile?)
Step 1. Download 950W firmware. (does it matter which version, there are like 15 different on SamMobile)
Step 15. Open IME setting on Factory Binary, I have no idea what this is, Is this something in the modified ODIN?
How to change carrier:
1. Download Factory Binary, EngBoot, and the G950W firmware. (i dont think engboot is needed i did it without eng boot and works)
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 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 (unmodded)
14. Click start
15. Open IME setting on Factory Binary
16. Type in *#243203855#
17. Select XAC
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 "XXX" > /efs/imei/mps_code.dat
22. Type in exit into adb shell
23. Type in adb reboot bootloader
24. Flash the G950U firmware of your choosing without Userdata. Also make sure to flash the non-home CSC
25. Enjoy your new carrier!

I've actually found you can simply:
flash engboot w/mod ODIN
Boot phone, enable usb debugging
adb shell echo "ATT" > /efs/imei/mps_code.dat
flash full stock firmware (any carrier) in stock ODIN w/non-home CSC
upon reboot, you'll boot with att features

Thanks for the reply, I flashed Engboot with PrinceComsey ODIN and it erased my data and reboot me to setup (hope this is normal).

Doesn't the unlocked version have different bands than the att version? It is my understanding that if you have att service that att branded version has wifi calling, volte, and virtual voicemail. Correct?

All S8 use the same hardware, the software/firmware dictates which bands/features are active.

Thanks for the reply, I flashed Engboot with PrinceComsey ODIN and it erased my data and reboot me to setup (hope this is normal).

Since you have unlocked phone, you may need to flash carrier firmware before getting access to /efs/IMEI
Although, the unlocked one may not have that file either. Not sure...

If you compare them side by side at Samsung.com, the unlocked version has less bands than the att version.

I've actually found you can simply:
flash engboot w/mod ODIN
Boot phone, enable usb debugging
adb shell echo "ATT" > /efs/imei/mps_code.dat
flash full stock firmware (any carrier) in stock ODIN w/non-home CSC
upon reboot, you'll boot with att features

A question for bit a of clarification:
I understand that you flash full stock with the Non-Home CSC, but which Non-CSC, the one containing Cache, PIT, and OMR or the other with Cache, and UserData?
Thanks.

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.

OP what's the difference between this and this: https://forum.xda-developers.com/ga...covery-stock-t-mobile-950u1-firmware-t3670924 ?
I see that they are different file sizes, one is 2.9gb and the other is 3.4gb .

I keep getting "odin model dismatch fail". Any help would be appreciated.

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.

download the firmware and follow the process above.
i can confirm going from tmobile to unlocked firmware and vise versa.

Unable to flash back BST rom after flashing ATT rom

I have a Boost 205U. I managed to flash an ATT rom using the patched ODIN. But I need to flash the Boost rom again so that I can request a sim unlock. The flash goes successfully (BL, AP, CSC, Home) but I still see it sticks to ATT (shows the ATT logo, csc is att). I verified that the rom I'm flashing is a BST
What could be causing this issue?

3. Flash each part of the firmware into its slot.
BL_20xxxxxxx.tar.md5 goes into the BL slot
AP_20xxxxxxx.tar.md5 goes into the AP slot
CP_20xxxxxxx.tar.md5 goes into the CP slot
CSC_xxxxxx.tar.md5 goes into the CSC slot

I did that. Matched each of the files correctly. But I keep seeing ATT. I've also tried downloading other versions of the Boost firmware but the CSC still shows up as ATT. Something is off!

CSC is supposed to erase everything unlike CSC_HOME. I did however flash CSC_HOME with the same result Something is awfully off! :silly:

Y0u can't decrease your baseband binary number

I'm aware! I flashed the same baseband (and even went higher since) to no avail.

I found the solution.
Make sure to use the right SIM before flashing. It picks up the carrier info from the SIM.
If you need it to show BST, flash an non-carrier (that comes with unlocked phones) ROM, type in *#272*IMEI, select the carrier you want to change to and voila!

Newer versions of phones have small packages that change depending on the sim inserted.
Learned that the wild way with a galaxy 9 plus

Just wanted to know if you had any issues with network not working with sims on the phone ?
