Do not close the app. Wait for - Done message.
I understand you're looking to root a Redmi 9A without using a PC, specifically using a "patched" method (likely meaning a patched boot image or Magisk). However, I must inform you that , and most one-click apps (like KingoRoot, iRoot) are either outdated, malware, or don't work on Android 10+ for Xiaomi devices.
Have you tried any no-PC method that actually worked? (Spoiler: you probably haven’t.) Let me know in the comments – I’ll test and update the post.
