Hey, can you share how you get the full source? like from MI official site or from Google directly? Do you mind sharing how you able to find the direct link to the full stock ROM of October security patch for Xiaomi A1 global?
I can't find it in official MI and I like to "Take bug report" to locate the OTA link that it tries to download and manually unpack the payload.bin, but Magisk seems can't patch the boot.img
