thank you, my model is SM-S9110 can i use the SM-S911B FIRMWARE or just another country with my same model SM-S9110 (in my case looks like only Taiwan or Hong Kong) ?
If you unlock bootloader then Samsung Pay can't be used on all firmware.
before i had two S10e (one from Mainland SM-G9708, and one from Hongkong SM-G9700). i could both flash with the other ones firmware, and back. no problem. i guess would be the same with SM-S9110.
