Posting it here so everyone knows:
Code:
C:\Users\User>fastboot boot boota_patched.img
Sending 'boot.img' (38708 KB) OKAY [ 0.894s]
Booting FAILED (remote: 'unknown command')
fastboot: error: Command failed
It's as we expected.
Everything went ok and normal. In other words I have root access.
My gratitude is huge. Hit me with a PayPal addresses for 2 cups of coffee.
Now going to test adding support for said app. (kanji study)
