?? find the motorola fastboot file called mfastboot and use that instead of normal fastboot.

( or :
- open the Phone app and enter the code : “##7378423#*#”. as if you were dialing a phone number (voice call ? )
- a new window should pop up.
- navigate to Service info and then to Configuration*.
- On this screen, look for the “Bootloader unlock” heading
- see if there’s a “Yes” next to it. If there’s no next to the heading, the bootloader is locked )

INSTEAD :
- restart phone in normal mode
- copy the TWRP image to SD card via usb (? in de “root” folder van shared storage , dus boven /Documents /Download etc )
- temporaly boot into TWRP from pc :
./adb reboot bootloader
./fastboot boot twrp-3.2.1-0-athene.img
=> lukt ook niet
locatie .img ?

then TWRP : menu > advanced > select the image and choose flash current twrp ( to recovery )
