Hello, you dont need to upload 16GiB of dump files.
Just cut sector of the dump to 128MiB is enough. You can do this via HXD program.
Open your dump files using HXD, go to edit, select block, and fill the block like this :
After that, do copy(ctrl+c), create new file(ctrl+N), go to Edit, make Paste Insert(Ctrl+V), then do Save As 128MiB of dump files, make compress using 7zip, and upload here.
