Redmi Note 9 Pro: Xiaomi replacement battery not working

Mon, 02 Feb 2026 18:15:04 -0700

My phone battery is addicted and I bought a new one and replaced it but I can't get my phone to work.

I bought an original BN52 battery that is compatible with this device.

The only thing that I see is the notification led blinking when I connect the new battery.

I already try to disconnect the battery, plug the charger, connect again and the behaviour is the same.

I already try 2 new batteries without sucess.

Any sugestions?

Redmi Note 9 Pro: Audio Chip/Codec not working.

Wed, 15 Oct 2025 11:02:47 -0700

My phone’s audio completely stopped working. None of the outputs or inputs work – headphone jack, USB‑C audio, the build-in speaker, Bluetooth sound, and the built-in microphone are all dead. I’ve reflashed the system and firmware, but the issue persists.

Looking at the logs, the system cannot detect any audio device, and /proc/asound/cards shows nothing. It seems the audio codec (audio IC) is not being recognized by the system.

Could you help me diagnose or repair this issue?

Ps: I bet the audio codec/chip/card (as you call it) is broken.
