android - fastboot and adb not working with sudo -

-

i have weird issue on ubuntu machine when trying run fastboot command.

when run:

fastboot devices

i get

no permissions   fastboot

so run command adminidtrator permissions:

sudo fastboot devices

and result

sudo: fastboot: command not found

how can be? have directory in path , works correctly without sudo.

instead of forcing permissions via sudo each time need run fastboot, can permanently fix issue:

  1. use lsusb identify device usb vendorid
  2. configure udev set proper permissions when device plugged in
  3. profit!

as bonus - fixed adb too.

for example, in case (for 'megafon sp-a20i') :

$ fastboot devices no permissions  fastboot $ sudo fastboot devices [sudo] password kaa:  medfielda9055f28    fastboot $

let's fix:

first, need identify device:

a) usb bus number (hack: know device intel-based one)

$ fastboot -l devices no permissions         fastboot usb:1-1.2 $ lsusb |grep 001 |grep -i intel bus 001 device 044: id 8087:09ef intel corp.  bus 001 device 002: id 8087:0020 intel corp. integrated rate matching hub $

b) other intel devices: 

$ lsusb |grep 8087 bus 002 device 002: id 8087:0020 intel corp. integrated rate matching hub bus 001 device 044: id 8087:09ef intel corp.  bus 001 device 002: id 8087:0020 intel corp. integrated rate matching hub $

hubs not smartphones definetely, - usb vendorid need "8087".

second, configure udev (you must replace "idvendor" value yours) :

$ sudo sh -c "echo '# megafon sp-a20i' >> /etc/udev/rules.d/51-android.rules" $ sudo sh -c "echo 'subsystem==\"usb\", attr{idvendor}==\"8087\", mode=\"0666\", group=\"plugdev\"' >> /etc/udev/rules.d/51-android.rules" $ sudo service udev restart udev stop/waiting udev  start/running, process 1821 $

third, re-plug device allow udev perform it's magic.

final check:

$ fastboot -l devices medfielda9055f28       fastboot usb:1-1.2 $ adb devices list of devices attached   $ fastboot reboot rebooting...  finished. total time: 0.253s $ sleep 90 $ adb devices list of devices attached  medfielda9055f28    device  $

voila!
