Note: Always verify your specific model (e.g., Redmi 9, 9A, 9T, or 9 Power) as pin locations differ between variants . Power Off: Ensure the device is completely powered down.
The phone is stuck on a black screen and won't boot into System, Recovery, or Fastboot.
Look near the bottom of the motherboard (near the charging port flex cable). You are looking for two tiny, unlabeled gold dots (circles) about 2mm apart. On the Redmi 9 ( lancelot ), these are usually located near the EMI shield, close to the battery connector. Do a Google image search for "Redmi 9 test point location" to see the exact photo—this is critical.
