    not sure how LG does it, but you will most likely have to flash a firmware update. this should fix your issue. also we need some more background details.....like how did this happen? did you flash something? why are you trying fastboot? remember the more details you give us, the better we can help.

    also what do you mean "fastboot reboot" doesn't help? what happens? nothing? error? can you post a screenshot of your adb fastboot commands?

    do you have adb and fastboot setup correctly? are you using the adb commands in the right folder? if you type "adb devices", does adb see your phone? can you post screen shots of your commands?

    I had to know how to use boarddiag to reinstall the phone so the firmware extract says out of memory so what way to reinstall without download mode is?

    are you sure you have the right file for your phone? where did you get the "fastboot system .img"?

    and as far as your "invalid sparse file format header" error you can try this:
    https://forum.xda-developers.com/t/tool-sparseconverter-v1-0-1.2749797/

    where does it say "out of memory"? on your phone? and you are asking about how to install firmware, correct?

    what is your exact model?
