Same here, new version of lgu, cannot be opened, file signature
(or magic number if u prefer) is now ULC2.
And the archive in the lgu container is no more RAR but a Zip tipe, as usual seen inside the file with the hex editor, i tried to cut out the archive but archive won't work i suspect that's somenthing like a byte shift or other kind of "protection".
I have spotted that at address from block 18 to 1B is stored that crc in reverse way.
But i'm not found the way to recover the internal archive.
Did you have a new version? (If u are still around here, seems that these posts are the only 2 that you are ever made
Thank you in advice.
Are you working with new medianav evolution firmware too?
