Just now I have received an update notification for MIUI firmware update for Xiaomi Mi4 (Mi4w) phone. Update version is V18.104.22.168 KXDMICH with 135MB file to download.
As of now I've connected to a working wifi network. Still, I'm getting a problem downloading the update. It shows the error : something went wrong. Please try again later. Tapped many times, not downloading yet.
I am currently having MIUI V22.214.171.124(KXDMICF) stable firmware. I've attached the screenshots below.
Will update asap.
