Mi 9T Pro to Redmi K20 Pro conversion patch (MIUI 11 & 12)

Mhh I flashed the minimal patch and now I have a k20 pro, however Amazon still won't show hd (fresh install). I remember when xiaomi.eu was a k20pro by default I could watch HD videos so what am I missing?
You have to clear "All app data" of Amazon Prime app. :)

Also check the Widevine level of your device/ROM with "DRM Info" app. ;)
