1. your modified fastboot won't work unless using `chmod +x ./fastboot`
2. When I used original fastboot
for first time
`fastboot oem get_identifier_token
FAILED (Device sent unknown status code: SNIdentifier token:
)
fastboot: error: Command failed
`
and when I used it again
`fastboot oem get_identifier_token
FAILED (Device sent unknown status code: SNxxxxxxxxxxxxxxxxxxxxxxxxxxxx
)
fastboot: error: Command failed
`
and that number xxxxxxxxxxxxxxxxxxxxxxx is same as result from your modified fastboot, and both are resulting same error `dd: invalid number: ‘’`
3. Another Error: `./signidentifier_unlockbootloader.sh: 88: let: not found` and I passed It by removing `let`
