Samsung Pay on Rooted (0x1 Status) Phone

[schwags]

OK guys, sorry I know this has been brought up a bit, but I've been determined to find a solution. I've been trying to get Samsung Pay to work. More specifically because I use it a lot and have a Gear S3 that I want it to work with.

Yes I did research before I rooted, and it appeared there were many solutions to this problem, but I've tried them all and none have worked. I just want to see if anyone at all has got this working. Maybe I can update with different things everyones tried as we go. I feel like there HAS to be a way to make this work. If anyone has gotten this to work in any way, please post!

My Phone: SM-G950F
Knox Status: 0x1 (Faked 0x0 by Magisk)
ROM: Renovate Ice 5.1
CSC Version: SPE (Spain)

From my research, the SPE seems to be open to Samsung pay along with some others. I have encountered different error messages with different combinations of software, hiding Samsung Pay in Magisk, etc. It might just be due to newer and older version of Samsung Pay

Things I've tried:
Fake 0x0 with Magisk, v13.6, 13.7, 14.0
Hide root status with Magisk
1.3.7 Samsung Pay Gear Plug-In (I found somewhere that said this version works, although it just keeps updating for me)
Moved /system/xbin/busybox to SD card

Error message I'm receiving on latest software: Access Denied: Samsung Pay has been locked due to an unauthorized modification. Tap the link below to call customer service and unlock Samsung Pay (RD-SXA).
Note, I have not tried calling customer service yet, that will likely be my next step. I will just tell them I bought the phone on eBay and I'm getting this message. I doubt there is anything they can do, but it's worth a try.

Please don't grill me, I know basically everyone claims this is NOT possible with 0x1 due to hardware fuse, etc. I know this community is strong and I've seen people pull off the impossible before, just hoping to get this to work so my S3 Gear doesn't become a paper weight.

The actual functionalities of Samsung Pay (MST for example) are handled by trusted apps running in secure world. Root in normal world does not affect anything there. Saying that we can fool normal world apps, we still can't fool the TA running in secure world. So even though Samsung Pay app can launch, it won't be able to function in the end.

OK, I have an update. I was able to get Samsung Pay (mobile version) to work! The regular version still gives me an error, but if I launch from my watch, it pulls the mobile version instead.

Here's what I did:
**NOTE: This only works if you have a Gear S3, I have not been able to get the full version of Samsung Pay to work on the phone yet.

1. Boot into recovery
2. Wipe all partitions except the SD Card and OTG
3. Installed Renovate Ice 5.1
4. Select Custom CSC during install and chose "214 Spain"
5. At the end of setup, don't reboot, flash magisk again manually (It's installed in the ROM, however this is the only way I found to get the icon to show up)
6. Open Magisk Manager
7. Click Menu and go to "Magisk Hide"
8. Search for "Pay" and check all apps that show up
9. Update all apps and connect S3 as a new device (you can restore apps/settings)
10. Use root explorer to /system/xbin and move busybox to your SD card (Make sure it doesn't exist on internal storage, if it's present, app will fail)
11. Launch Magisk Manager again and search for "Pay", again make sure all are checked, for me there was another new Gear version that I had to check to hide
12. Reboot the phone
13. Hold down top button on S3 to launch Samsung Pay
14. Proceed through wizard and add a card or "Launch" Samsung Pay on the phone from the S3
15. The Samsung Mobile app should open correctly on the phone and let you add cards etc.

If you try to add busybox back and reboot, it will not work. And again, the actual "Samsung Pay" app on the phone does NOT work, I still get an error. Maybe it's not possible.

Nice findings! So Gear S3 has stand alone pay capability even with non-Samsung devices?

I'm not sure about non Samsung devices. All I'm saying is there are 2 versions of Samsung Pay on the S8, one standard version that you would use if you didn't have a Gear S3 and another version that s triggered from the S3 but then runs on phone. That's the one I can get to work.

Does this method work with renovate 7.2? I have followed the steps and appears denied access

Same problem here, and I live in Spain too!
Does it work with other rom?

I have an sm 930f with 0x1 status, also. since the error message has changed and suggests "call customer service to unlock samsung pay at 0330 726 7729" I just got off the phone with UK customer service.
1. agent didn't know anything about unlocking samsung pay
2. since I reside in the U..S he suggested I had to call U.S customer service which I have already done and they know nothing about unlocking samsung pay. Perhaps there's a change in the works but not yet.

I wonder what happens if the flash counter hits 0x9. One more flash and it hits 0x10 or does it go back to 0x0??
