HELP with Netflix 2.11 update on CFW 4.21

Hello,

Can someone here let me know how can I successfully resign this update pkg?

URL= b0.ww.np.dl.playstation.net/tppkg/np/NPUP00030/NPUP00030_T23/9f0bf66d8933d9df/UT0007-NPUP00030_00-NETFLIXRIGEL01NA-A0211-V0100-PE.pkg

I tried the following without success:

1. Install original pkg
2. FTP with Multiman and copy the EBOOT.BIN and all SPRX and SELF files to my PC
3. With TrueAncestor, I resigned the EBOOT.BIN and all SPRX and SELF files.
4. Copy back all the resigned files through FTP to the game folder again.
5. Done.

When I start Netflix I got a black screen and then the game returns to the XMB :dontknow:

What am I doing wrong?

Any assistance will be greatly appreciated.
