If I switch from Verizon s8+ firmware to the US unlocked firmware, can I switch back if I wanted too? I thought I remember reading that a couple weeks ago that you couldn't.
Carrier Switch Snapdragon
- Thread starter mweinbach
- Start date
I am like 99.9% sure. Both are valid firmware flash back and forth to your hearts content.
Yes you can .
Use latest Odin to flash the Verizon firmware and use the patched odin to flash the unlocked firmware.
flash the TMB userdats andswitch csc to TMB.. once done should read TMB/TMB/VZW

you definitlely can switch back from U1 not a problem at all.. you will need reg odin and comsey.. if one doesnt work (model dismatch) use the other odin
Thank you elliwigy!!!
1) Will my phone still be unlocked and receive the Unlocked Firmware OTA updates If I do this?
2) For the TMB Userdats? Is it the user data from this post?

3) how do you switch the CSC to TMB?

I'm trying to do this and step 15 I'm not sure how to do. Can you tell me how to open IME setting on factory binary?
on factory binary there is an icon for "IME" LOL just open it by tapping it

then enter the code in next step..
Maybe a bit off topic but figured the more threads its posted the more people we will have searching for needed files!
To update everyone, everyone should know by now we can get into Emergency Download Mode (EDL.)
Although this is great, we are at another roadblock lol. We cannot actually flash anything yet since we need some programmer files and an xml file.
Apparently they exist but Samsung owns them as they are proprietary so Qualcomm doesn't provide them, need to be obtained by Samsung.
I know someone who has them but as of right now he is not willing to share (he has his reasons.) Let's not get off track again and complain and try to locate the files by other means.
Once we have said files, we can then flash away and work can be done for root for sure, and theres a good chance we could even have TWRP!
I also have ENG root boot for G955U so once we can find these files we can flash it and most likely release it if I get the green light.
With that being said, the files needed are:
1) prog_ufs_firehose_8998_ddr.elf
2) prog_ufs_firehose_8998_lite.elf
3) provision_samsung.xml
Also a picture is provided below as proof they exist. Keep in mind these files are specific to the Snapdragon 835 UFS msm8998 (the US S8/S8+.) Without these files we cannot utilize edl to flash as we need to set it prior to a flash in QFIL or Mi Flash tools or other tools that are capable of flashing in EDL mode.
Another potential avenue is similar to the Axon 7 if someone can write up acustom ADB/Fastboot exe that can communicate in EDL then we can simply run a cmd to flash boot and/or recovery (in theory.)
If you locate any of these files please PM meand we will bring you into the HO and we can get the ball rolling!
We are close but so far still... We have at least 4 othersactively seaking these files. More brains in finding them is needed. If anyone knows anyone that can access Samsung servers or GSPN (business affiliates) then try to get them to help us out!

The "Factory binary" file I downloaded from here:
https://forum.xda-developers.com/galaxy-s8+/how-to/carrier-switch-snapdragon-t3615680
I don't see an IME when unzipping this file. I'm sure I'm not doing this properly so I apologize but I really need to figure this out.
So just to be clear I can use this to convert my sprint s8+ into a unlocked variant? Sorry for the redundant question been away from the android game for almost a year wife made me get an iPhone and I'm glad to be back
I don't know if I could get these. Try getting that person to share then I guess. Would these work on the S8 and S8+ with the same files?
i am not sure to be honest lol i would think itd be fine for both s8 and s8+ as i dont see where theyd distinguish the two in the name of file
please check this

in the comment he said he had s8 service ready? not sure what it is
Can you show me a screenshot of what you are talking about? I think I'm not looking at this right.
I bought a SM-G955UZKAXAA Unlocked US S8+ from Samsung.com and would rather just leave all the firmwares alone but after reading this post saying T-Mobile works fine but also reading tweets like this from T-Mobiles CTO I dunno who to believe?

Should I just flash the T-Mobile firmware? Sucks using Samsung Caller ID and no bloat.
