I'm also awaiting for this... Stable 10.3 fo Redmi 4X was released today/yesterday, and our rosy should be near.Hello,
When will be Xiaomi.eu 10.3 STABLE for REDMI 5?
BTW, do you know any official TWRP that supports Oreo encryption? I have one which seems to be a personal mod, but i'd prefer an official one (TWRP 3.3 doesn't decrypt internal nor data)
