[Magisk] CONVE3RSION:
Sure! I don't know how to attach files so I pasted it below.

I used MagiskHide Props Config from Magisk to edit

ro.product.brand

and

ro.product.manufacturer

to change them from

samsung

to

htc

I'm on an S5 (kltedv, SM-G900i) using Resurrection Remix Pie v7.0.2 published on 2019-09-15. My watch is a Gear S3 Frontier (International Edition, SM-R760 on software R760XXU2ESF2/R760OXA2ESF2). My Galaxy Wearable app is version 2.2.29.20012861. My Gear S Plugin is version 2.2.03.19082641N. My Samsung Accessory Service is v3.1.93.90807.

Good luck :)
