• "lsusb": It's a typing error, thanks.
• "udev": you may need either to install the package, or to create an alias.
• "bootloader": did you tried to run the command as root user?

"bootloader": i can't acces root.
i cannot downgrade to flyme 4.54.l. i've put update.zip to internal and update via file manager then restart, but my phone just reboot. Not entering to recovery, because my recovery lost
before this, i install nethunter kali, and unchroot. and i was install busybox to /sytem/bin. since this ,the trouble began.
How to re-root again, after uninstall kingroot, i can get root anymore..Kingroot not work, just 70 % then end. my stock recovery lost too. Help!
im not install TWRP and not unlock bootloader before. flash recovery need root acces. now i dont have root acces to flash with rashr/flashify. i have change kingroot with super su script (sh /sdcard/mrw/root.sh)
when i uninstall kingroot, and run terminal android sh /sdcard/mrw/root.sh, it appear like this:

/ $ su
/ $ sudo su
/system/bin/sh: sudo: not found
/ $ sh /sdcard/mrw/root.sh
