This is a Beta Build! There may be unexpected bugs.

Changes:

  • Fix BB Hub Inbox notification actions missing, BB Notes crash (was affected by flawed fix of BB Keyboard personalized suggestions permission in last release)
  • Haptic feedback: Restore kernel 4.4 fingerprint vibration strength and device-specific tuning
  • Settings/System/Buttons: Add Search button (i.e. Assistant/Convenience Key), remove Menu button (not on Key2)
  • Fix network access being lost on each reboot for apps stored on SD card when using adoptable storage
  • Fix front-facing camera showing live image when camera access is blocked
  • Sept. 2026 Android platform security patch

Notes:

  • If you are using adoptable/internal SD storage on kernel 4.4 ROM (v1.10a-v1.12a): Before updating to v1.20c, migrate/backup all apps/files from the SD card, format the SD card as normal/portable storage, then repeat formatting as adoptable/internal storage after updating to v1.20c
  • Default ZRAM compression changed to LZ4 in kernel, but if you had previously forced a compression algorithm with persist.vendor.key2.zram.compressor, that manual override will persist. It is recommended to switch to LZ4 - see last section below.

Known Issues:

  • Some users experience ghost Recents input spamming on kernel 4.19 - under investigation
  • Double tap to wake (DT2W) is working intermittently at least for FocalTech/Livata panels - under investigation
  • USB-C screen mirroring crashes LOS

Update Instructions:

  • You cannot update to this ROM if you are running a Krab-v1.20+ or Krab-2.0+ build unless you wipe userdata
  • If you are running a ZKrab Key2 ROM from v1.9a-v1.12a: Download "lineage-22.2-20260915-UNOFFICIAL-zkrab-v1.20c-athena.zip" to your Key2 and perform local update through Settings/System/System updates/3-dot menu/Local update - Userdata wipe NOT needed!
    • You can return to v1.12a (kernel 4.4) with the same method if you experience issues with this build (again no userdata wipe needed)
  • If you are already running v1.20b: Perform an OTA update on your Key2 through Settings/System/System updates (the OTA update is downloaded from the first link below)
  • If you are currently running stock Blackberry Android 8.1 or an older LineageOS version, download "LOS22_Key2_ZKrab-v1.20c.zip" to your PC and follow this guide for install instructions: https://daphnis-past-midnight.nekoweb.org/wiki/key2.html

Choose ZRAM Compression Algorithm

  • To switch to lz4 compression (other options are lzo and zstd, but lz4 is recommended):
    adb root
    adb shell setprop persist.vendor.key2.zram.compressor lz4
    adb reboot
    (after reboot confirm change with:)
    adb root
    adb shell cat /sys/block/zram0/comp_algorithm
