wer to put bootlogo files

If you are installing a new one you downloaded this is usually an ipk package so ftp it to /tmp then do manual install via remote.
If you want to edit what you are already using the location is usually /boot but can differ depending on image especially open pli.
Ask if you need more info.

Bootlogo.mvi files go into folder /usr/share/, you must choose an image with 1280 x 720 resolution, and have chmod 755 or it wont show during bootup.
I use dream logo generator it will convert the image then ftp to the correct folder. Let us know how you get on buddy...
