r7 Release Notes

  • Based on odessa-11 tag (LA.UM.9.1.r1-09100-SMxxx0.0)
  • Massively debloated
  • Optimized frequency table
  • Custom thermal throttling solution
  • Merged all Sultan floral patches
  • zram, zsmalloc and zstd backported from mainline
  • mm backports
  • Merged Samsung’s memory management optimizations
  • Other optimizations from previous releases


This release is based on R tag, so this won’t work on Q ROMs. It works on stock Android 11. On custom ROMs, it’s compatible only with ROMs that use QTI power HAL. If you don’t know what that is, ask your ROM maintainer.

Companion Module

No longer needed with r7, remove it if you have it installed.


  1. Back up your boot and dtbo partitions. You can do this in two ways:
  • Use TWRP

  • Connect your phone to your PC and run these ADB commands:

    adb pull /dev/block/by-name/boot_a boot.img
    adb pull /dev/block/by-name/dtbo_a dtbo.img

    Replace _a with your current boot slot, which can be found by running this command in fastboot mode:

    fastboot getvar current-slot
  1. Flash the kernel ZIP from TWRP or using adb sideload on other recoveries.

Reverting to stock kernel

Restore your boot and dtbo backups. Depending on which method you chose, you can:

  • Use TWRP
  • Flash the images from fastboot via these commands:
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img

If you didn’t take a backup, you can dirty flash your ROM zip without wiping anything.
