Flashing Verizon SM-G960U to other Variants

Hello, I have a Galaxy SM-G960UZKAVZW, The Verizon model, and it is unlocked. I use this phone GSM in Peru, but It noticed that I can not switch freely between 4G and 3G like I could in a S8 Tmobile model.
So I have to Flash other firmware, if it is possible, I don't want any carrier logo so I need to know what firmware I have to choose. I looked into Sammobile for G960U and found:
Spint (cdma) (SPR)
USA (TMK) MetroPCS
USA (USC) US Cellular
USA (T-Mobile) (TMB)
USA (Verizon) (VZW)
Unknown (BST) Bosst Mobile
Unknown (CCT)
Unknown (XAS) Sprint XAS
Virgin Mobile USA (VMU)
What firmware I have to choose, or I need to choose a G960U1?
Then, I have to do wipes?
Thanks.
Use the one for the SM-G930U1 with CSC code XAA and flash with the modified odin found here on the forums

Flashing G960U software to G960W

Hi,
I'll be getting a Canadian S9 soon but i have no need for the device and i'll be sending it to my sister in the states (she is on AT&T). I want to know if i'm OK just flashing the latest version of the US firmware to the Canadian device? and what is the CSC of the unlocked version of AT&T in the states? Will she be able to update as usual after that and will Samsung pay work?
Thank you very much in advance.

S20+ CSC Change

Hello Everyone,
I have the SM-G985F/DS in Canada. The current CSC is XSP/XSP,XSP/XSP.
This phone is the international variant. Can someone please guide me on how I can change the CSC? I am a total noob. I would like Samsung Pay/ VoLTE to work. Preferably Fido CSC or Unlocked Canada, some bands aren't working properly.
If this isn't possible will I get updates for my phone?
This has been a big headache.
The phone is Exynos and I'm in a Snapdragon country.
Thanks

Since you're using an Exynos phone in a country where they officially sell the Snapdragon variant, you won't be able to flash the Canadian CSCs since they're only available for the Canadian variant.
VoLTE should work after you insert your SIM and reboot the phone, I've seen multiple reports of VoLTE no longer requiring the correct CSC to function.
Messing with band support is almost impossible on Exynos variants and I believe Samsung Pay requires the correct CSC to work so you're out of luck there.
All this aside, you will still get OTA updates based on when they're released for the XSP CSC.
