Thanks for your information

By following instructions found in XDA forums,
now I am able to install an unlocked bootloader,
boot among primary kernel, recovery kernel or fastboot,
an Android custom stock rom also has been installed

Could you please let me know how to install local built ubuntu images

Thanks,
