Checksums are possible and cheap why is nobody just checking it? 
This time, the new blob (as far as I can see it …) comes with the same old files. They just moved the four libs from libs dir to the system dir.
Just compare the last 4 lines with the old 4 libs on top. @tphysm I have not clue why one build works for you and the other doesn’t. But once the files are copied into the target system folder it should work the same.
