[RTW590]

I downloaded and used APAC_WM6_R0_Sprint for a long time and my device broke and I put it back on my phone, but know I see there is this new version and I do not understand how to install it. I tried looking through everything, but nothing helped. The last version I just downloaded and walked through it so this is all very new to me. Can someone give me a very dumb down step by step walkthrough of everything because I'm completely oblivious idk what the buildOS is or the Updater etc.
