• 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

• 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"

• 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"

• /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

mount '/system'

mount '/data'

mount '/cache'

mount '/firmware'

****

mount -a

adb shell

mount '/data'

rm -Rf '/data/dalvik-cache'

• 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

• Run after booting into TWRP

adb shell "mount -a || fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/firmware' && sync"

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

sudo fastboot erase 'all'

• 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
