ok thanks understood i havent clear if you were the picons logo updater. Its not a problem for me the picons are fine for me.
at this moment i have prefectly working. I tried to format with the dream and create a ext4 format usb with software diskgen i can read write on the usb under windows10.
one test that i would like to perform its format usb in ntfs and then check i already can give permission read/write to the folder because installed the drivers for linux on gp4 ntfs-3g.
the default attributes when i format the usb with dream in ext4 its 444 i think only owner can write.
Now with ext3 attributes 777 the plugin can write the picons on usb without problem. i check that previously extract the files from the tmp folder where is downloaded the zipped file.
