Seul, ça ne permet pas de créer de CFW !
Voici les remarques de MathieuLH concernant les fichiers tar du firmware 3.56 et supérieur, comparé aux firmwares précédents :
To those planning on building a 3.56+ pup for whatever reason, the files attributes changed, the group and user ids for the files as well.
The new 3.56+ values for tarballs are the following: owner_id, “0000764″ group_id, “0000764″ owner, “tetsu” group, “tetsu” ustar, “ustar ”
You can use fix_tar to use those new values. Use with caution.
By comparison, those are the pre-3.56 values. owner_id, “0001752″ group_id, “0001274″ owner, “pup_tool” group, “psnes” ustar, “ustar “
