Sorry to bring back an old thread, but this seems like the best place to post to. I'm stuck at step 11. Odin keeps coming back with a fail! (auth) error. I've done this before with a G950, but I'm not able to get past this part with my G955.

Try a different cable.

Tried 3 with different ports too. Same result
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
I have no idea then. Are you using the correct version of odin?
[Samsung Galaxy S8+ Guides, News, & Discussion] trebills:
Attached a screenshot of odin maybe you can see something I am not. I am new to Samsung. Use to Nexus/Pixel
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
If you are flashing the G950U1 firmware, you are good. If you are flashing a stock firmware, download regular Odin in the OP post.
[Samsung Galaxy S8+ Guides, News, & Discussion] pankaj981:
[MENTION=7277512]mweinbach[/MENTION] You may want to edit the OP that the Gear VR works now, atleast my Verizon S8 flashed to the 950U1 firmware. I am sure the 955U1 might work as well.

I'm trying to to convert to carrier unlocked. This is my first Samsung device, coming from an htc 10. When I boot into download mode, should the bootloader still say my carrier is vzw? I'm not sure how to do this properly.
[Samsung Galaxy S8+ Guides, News, & Discussion] Saythis:
Pretty sure it detects based on the Sim card but I could be wrong.
[Samsung Galaxy S8+ Guides, News, & Discussion] rando191:
Not sure if I'm doing something wrong but I am always stuck with TMB/TMB/VZW after doing all the documented steps here. Trying to switch from Verizon to T-Mobile. Everything appears to be working ok, just not sure if it's some hard coded VZW thing at this point?

Thanks!!
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
lol.... the last part will not change since u originally had a verizon device.. it shouldnt effect anything at all

[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
Thanks for handling this support stuff for me. I have been busy lately. I forgot to ask, who should I contact to try to get engroot? Let's see what I can find out.
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
no one right now.. i have been asked to not share it and i believe the only other person who has it.. the boot flashes but since we are on user binaries it wont get out of download mode...

he does have debug energency download firmware which he (i believe) was able to accomplish somwthing but i havent talked to him yet
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
Can you tell me who. I would like to join in on the development. I am not asking for the files. Just the person. You can send their name to me in a pm is you are willing to tell me

Does this allow me to flash my Verizon G8+ using Unlocked Firmware while using it on T-Mobile and keeping all of T-Mobiles features?

Currently I flashed the Unlocked Firmware, but it's missing features like Video Calling on T-Mobile.
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
use a activity launcher and enable it in IMS settings.

Thank you, can you please explain how to do it?

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.
[Samsung Galaxy S8+ Guides, News, & Discussion] JustusIV:
I am like 99.9% sure. Both are valid firmware flash back and forth to your hearts content.
[Samsung Galaxy S8+ Guides, News, & Discussion] guaneet:
Yes you can .

Use latest Odin to flash the Verizon firmware and use the patched odin to flash the unlocked firmware.
[Samsung Galaxy S8+ Guides, News, & Discussion] clintw22:
That was the one thing holding me back! Thanks guys!
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
flash the TMB userdats andswitch csc to TMB.. once done should read TMB/TMB/VZW

---------- Post added at 12:30 PM ---------- Previous post was at 12:28 PM ----------

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
[Samsung Galaxy S8+ Guides, News, & Discussion] notmilk:
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?

https://xdaforums.com/tmobile-galaxy-s8+/how-to/sm-g955u-odin-firmware-g955usqu1aqd9-t3593600

[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
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!

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
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
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?
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
yah
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
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

[Samsung Galaxy S8+ Guides, News, & Discussion] ChrisM47:
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?

https://twitter.com/NevilleRay/status/875151223577391104

Should I just flash the T-Mobile firmware? Sucks using Samsung Caller ID and no bloat.
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
Flash it if you want. I do believe he is wrong. I don't know how to check.
[Samsung Galaxy S8+ Guides, News, & Discussion] ChrisM47:
Lets prove him wrong! How do we do it? :p
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
Download the G955U firmware from SamMobile. Download modified Odin from first post. Enable adb. Type adb reboot bootloader. Put your files into Odin. Hit start. You would then have the TMB firmware. It will factory erase your phone so backup before.
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
i totally would if i was on binary firm but i am not lol i am trying to get us root and tgen some
[Samsung Galaxy S8+ Guides, News, & Discussion] Nexii5:
I see people in this thread mention they are on XAA/XAA/VZW or TMB/TMB/TMB etc.

How do I check this?
[Samsung Galaxy S8+ Guides, News, & Discussion] Smithfolk4:
You can look at Settings - About Phone - then scroll down until you see Service Provider. Mine is on the bottom line of that entry.
[Samsung Galaxy S8+ Guides, News, & Discussion] Nexii5:
Just checked and I don't have a service provider in that section. Weird!
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
u must be on U1 firmware
[Samsung Galaxy S8+ Guides, News, & Discussion] ChrisM47:
I mean I don't know for sure if all the T-Mobile data features are working but this is just the out of box firmware of the US Unlocked S8+ haven't flashed anything and I've never seen data speeds like this.

[Samsung Galaxy S8+ Guides, News, & Discussion] guysohigh:
I tried to the do carrier switch method, however, I could get the HOME_CSC from the 955W firmware to flash correctly, and I could get XAS installed from the IMEI menu on the phone. So I gave up ,and just went with the unlocked firmware, figuring it'd be better than stock Verizon. However, when the unlocked firmware loaded, I got the TMB update through Samsung SmartSwitch as detected from my SIM card. So it looks like it'll pickup and update the firmware based on the SIM card carrier, from the unlocked firmware. Of course, if you wanted, you could just stay on the unlocked firmware.
[Samsung Galaxy S8+ Guides, News, & Discussion] mellojosh:
The original post states that Verizon Wifi Calling is working, but I do not see any menu option for this under phone settings, connection settings or have an Advanced Calling menu. Can anyone else confirm?
[Samsung Galaxy S8+ Guides, News, & Discussion] Smithfolk4:
Verizon wifi calling won't work just using this method. If you look in the S8+ Verizon forums there is one that shows how to get it working. Also, there is now a ROM in the Verizon S8+ ROMs forum that should get it to work. Yes you can flash the ROM in ODIN. Check the Forum.

[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
Just flash the U1 firmware in ODIN.. it's carrier bloat free and your device is already unlocked so it should work out of the box

I somehow had a driver issue. It is fixed and all is well. Thanks for the help!!
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
thats dif. than previous s reen.. that shows its connected n begins flashing partitions then disconnects for some reason during process..

honestly doesnt seem download related.. have you tried dif cords, dif ports, u have samsung drivers installed etc?

u are only getting a conn short time its either losing conn immediately or during flash.. that is not an odin failure or rom failure but a conne tion failure..

is your usb port wrt or damaged?

Thanks

EDIT:Found it and now in IME menu, SOmehow i cant enter that *# command as its vibrate and show error "The process com.android.phone has stopped" Anyone please?
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
why not just flash the U1 firmware and bypass all the steps?
[Samsung Galaxy S8+ Guides, News, & Discussion] gotojanoo:
Haha originally it was unlocked version U1. I converted to T-mobile firmware successfully but had that TMB/TMB/XAA so I was thinking if I can change that XAA to TMB by flashing t-mobile CSC.
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
so original device is a U1? you didnt read up on software codes i assume lol that last XAA is hardwired in the device, you can never change it lol

so you are essentially wasting time trying to do so
[Samsung Galaxy S8+ Guides, News, & Discussion] gotojanoo:
Yes you are right last XAA can't be changed I read that. But I had also read somewhere here in XDA that someone was able to make all TMB/TMB/TMB. So i was just giving a shot. Binary keep giving me an error so I gave up. Flashed back latest T-mobile firmware lol. Working great. Still that XAA there not big deal. :) If its hard coded with variant there is nothing we can do as you says. Thanks though.
[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
whoever said that probably has tmb originally and went to xaa then back lol

G955u1*? I mean lol
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
When TMobile releases an update, if you flash it you will be on the Sprint firmware but newest update. App updates for all carriers are the same. You can't go onto the G955U1 firmware and get those updates because Samsung does those updates.
[Samsung Galaxy S8+ Guides, News, & Discussion] lethalboy:

flashing the HOME_CSC of the G955u it goes through but starts with the process com.android.phone has stopped close app. and i cant proceed from there on. .

any ideas?

much appreciated

thanks
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
You need to use missed Odin.
[Samsung Galaxy S8+ Guides, News, & Discussion] naack:
Missed ?

I get model mismached in moded Odin.

Normal Odin I get the errors mentioned in m previous post. After booting.
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
Are you trying to do it on the S8 or S8+. This stuff is for the S8+. If it's for the S8 just switch it for the G950 files. If not, try flashing the G955U1 home_csc then G955W home_csc then type the code into IME. They might have done some stuff to fix this. I don't know. But once you get it once, you just need eng binary and the command. Try that then do what I said before for the G955U1 and G955W.
[Samsung Galaxy S8+ Guides, News, & Discussion] naack:
mweinbach, thanks that helped. but i cannot get the spint logo. i

is this supposed to change the 3 letter carrier on the download mode page?

nevermind i got the logo back not sure why i wanted that haha.
[Samsung Galaxy S8+ Guides, News, & Discussion] mweinbach:
even if you got your answer, you do it after you launch your phone. you can do it at any time after this as long as you are running on the engboot.

Hi guys. I'm kinda confused about all these S8+ models.

[Samsung Galaxy S8+ Guides, News, & Discussion] elliwigy:
well that depends on what carrier u r on.. if someone say has an unlocked verizon device and wants to use it on tmobile and get the tmobile bells and whistles theyd need to carrier switch..

some carrier specific features such as volte or wifi calling would only work on carrier specific firmware

thats only benefit i can see to be honest lol
