It worked, thanks.well, i'm not really sure if its help, but try to use fresh Ultarhand, first delete your Ultrahand ovl in folder /switch/.overlays, and delete Ultrahand folder in /config/ultrahand, after that restart and copy new update Ultrahand, and run for the first time, and check the folder ultrahand in /config/ultrahand, you should find 2 zip file nx-ovlloader inside it.
** don't forget to backup folder in /config/ultrahand first, in case you use some custom setting.
I wanted to know how you created this command and where the text file is?
