• 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/mmcblk0p39' && e2fsck -y -f -v '/dev/block/mmcblk0p40' && e2fsck -y -f -v '/dev/block/mmcblk0p41' && e2fsck -y -f -v '/dev/block/dm-0' && mount '/system' && mount '/data' && mount '/cache' && mount '/vendor' && rm -Rf '/data/dalvik-cache' && fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/vendor' && sync && umount '/system' && umount '/data' && umount '/cache' && umount '/vendor' && reboot"

• /dev/block/dm-0 is /data and /sdcard
• /dev/block/mmcblk0p39 is /vendor
• /dev/block/mmcblk0p40 is /cache
• /dev/block/mmcblk0p41 is /system
• All 5 partitions are ext4

• Do nothing else and immediately re-flash bootloader if it's wiped

fastboot erase bootloader

fastboot erase radio

fastboot erase recovery

fastboot erase boot

fastboot erase vendor

fastboot format vendor

fastboot -w

umount '/sdcard'

umount '/data'

umount '/cache'

umount '/system'

e2fsck -y -f -v '/dev/block/dm-0'

e2fsck -y -f -v '/dev/block/mmcblk0p39'

e2fsck -y -f -v '/dev/block/mmcblk0p40'

e2fsck -y -f -v '/dev/block/mmcblk0p41'

mount '/system'

mount '/data'

mount '/cache'

mount '/vendor'

adb shell

mount '/data'

rm -Rf '/data/dalvik-cache'

• If done immediately after booting TWRP, /data and /cache are already mounted, but /system and /vendor aren't

adb shell

mount '/system' && mount '/vendor'

fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/vendor' && sync

• Run after booting into TWRP

adb shell "mount '/system' && mount '/vendor' && fstrim -v '/system' && fstrim -v '/data' && fstrim -v '/cache' && fstrim -v '/vendor' && sync"

• Expects a factory image folder extracted to ~/Downloads starting with the name bullhead
• Flashes bootloader and radio partitions

sudo fastboot flash 'bootloader' ~/'Downloads/bullhead-'*'/bootloader-bullhead-'*'.img' && sudo fastboot reboot-bootloader && sleep 5 && sudo fastboot flash 'radio' ~/'Downloads/bullhead-'*'/radio-bullhead-'*'.img' && sudo fastboot reboot-bootloader

• Expects a factory image folder extracted to ~/Downloads starting with the name bullhead
• Expects a image-bullhead zip archive in that factory image folder
• Flashes boot and vendor partitions

unar -o  ~/'Downloads/bullhead-'* ~/'Downloads/bullhead-'*'/image-bullhead-'*'.zip' && sudo fastboot flash 'boot' ~/'Downloads/bullhead-'*'/image-bullhead-'*'/boot.img' && sudo fastboot flash 'vendor' ~/'Downloads/bullhead-'*'/image-bullhead-'*'/vendor.img' && sudo fastboot reboot-bootloader
