Custom kernel list for Xiaomi “juice/chime” devices

This article is no longer maintained as I don’t have the device anymore.

Notes:

  • juice = kernel based on stock MIUI vendor
  • chime = kernel based on OSS vendor
  • Both codenames is unified codename made by 3rd party devs for POCO M3 (citrus) & Redmi Note 9 4G/Redmi 9 Power/Redmi 9T (lime, lemon & pomelo). It is used in custom ROM builds. Thus, it is ONLY COMPATIBLE for these four models!
  • Bootloader must be unlocked first using this tool
  • It is up to you to determine which kernel works the best.

Custom kernel:

GreenForce kernel

  • Made by Mhmmd Fdlyas and Zecho Satria
  • Continuous Intergration (CI) builds, frequently updated
  • TD4330 panel supported too
  • Builds are posted in Telegram group below
  • Needs decrypted vendor
Telegram group
Telegram CHannel

There is also custom kernel named Anya/Twilight kernel (successor to SucksGuuji kernel), but they usually bundled with custom ROMs, so there is barely (atleast publicly) any separate kernel zip made.

Notes:
