Notes

  • Can only be done within TWRP Recovery either via built-in Terminal or over ADB
  • Ideal to do before a clean ROM flash, after an improper shutdown, and/or after configuring all apps/copying over all data

Quick-commands

ext4

Encrypted

  • This expects /data and /cache to be ext4
  • This expects /data to be encrypted
  • Boot TWRP, enter encryption password, and immediately run the following from a computer
adb shell "umount '/sdcard' && umount '/cache' && umount '/data' && e2fsck -y -f -v '/dev/block/mmcblk0p41' && e2fsck -y -f -v '/dev/block/mmcblk0p26' && e2fsck -y -f -v '/dev/block/mmcblk0p21' && e2fsck -y -f -v '/dev/block/mmcblk0p1' && e2fsck -y -f -v '/dev/block/dm-0' && e2fsck -y -f -v '/dev/block/mmcblk0p38' && mount '/system' && mount '/data' && mount '/cache' && mount '/firmware' && rm -Rf '/data/dalvik-cache' && fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/firmware' && sync && umount '/system' && umount '/data' && umount '/cache' && umount '/firmware' && reboot"

Unencrypted

  • This expects /data and /cache to be ext4
  • This expects /data to be unencrypted
  • Boot TWRP, enter encryption password, and immediately run the following from a computer
adb shell "umount '/data' && umount '/cache' && umount '/sdcard' && e2fsck -y -f -v '/dev/block/mmcblk0p41' && e2fsck -y -f -v '/dev/block/mmcblk0p26' && e2fsck -y -f -v '/dev/block/mmcblk0p21' && e2fsck -y -f -v '/dev/block/mmcblk0p1' && e2fsck -y -f -v '/dev/block/mmcblk0p42' && e2fsck -y -f -v '/dev/block/mmcblk0p38' && mount '/system' && mount '/data' && mount '/cache' && mount '/firmware' && rm -Rf '/data/dalvik-cache' && fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/firmware' && sync && umount '/system' && umount '/data' && umount '/cache' && umount '/firmware' && reboot"

Information

  • /dev/block/mmcblk0p41 is /system
  • /dev/block/mmcblk0p38 is /cache
  • /dev/block/mmcblk0p42 is /data and /sdcard
  • /dev/block/mmcblk0p1 is /firmware
  • All 5 partitions are ext4

Unmount Partitions

umount '/system'
umount '/cache'
umount '/data'
umount '/sdcard'
umount '/firmware'

AIO

umount '/system' '/cache' '/data' '/sdcard' '/firmware'

ext4 Filesystem Maintenance

e2fsck -y -f -v '/dev/block/mmcblk0p41'
e2fsck -y -f -v '/dev/block/mmcblk0p38'
e2fsck -y -f -v '/dev/block/mmcblk0p42'
e2fsck -y -f -v '/dev/block/mmcblk0p1'

Mount Partitions

mount '/system'
mount '/data'
mount '/cache'
mount '/firmware'

AIO

mount -a

Clear Dalvik/ART Cache

adb shell
mount '/data'
rm -Rf '/data/dalvik-cache'

fstrim

  • If done immediately after booting TWRP, /data and /cache are already mounted, but /system and /firmware aren't
adb shell
mount '/system' && mount '/firmware'
fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/firmware' && sync

Quick-command

  • Run after booting into TWRP
adb shell "mount -a || fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/firmware' && sync"

Erase Everything

  • This requires a radio re-flash 1)
  • This does not erase the bootloader nor recovery
sudo fastboot erase 'all'

Flash Base

  • Requires a Factory Image extracted to ~/Downloads
sudo fastboot flash 'bootloader' ~/'Downloads/shamu-'*'/bootloader-shamu-moto-'*'.img' && sudo fastboot reboot-bootloader && sleep 5 && sudo fastboot flash 'radio' ~/'Downloads/shamu-'*'/radio-shamu-'*'.img' && sudo fastboot reboot-bootloader
