After downgrade only older app on Smartub ?

[lighttear]

Hi all,
I have a BD-D6900 BD player and I tried succesfully DNS trick for downgrading (from B-FIRURDEUC_001012 to PATCHED B-FIRURDEUC_001103 (real 001003).
After that I supposed not to have SamyGo extension installed, so through develop user account I syncronized with SamyGo server, but after 100% download I didn't get any message for 10 minutes, I pressed "return" key on the remote but nothing happened.. after other 5 minutes a live tv channel was tuned;
so I launched smarthub and discovered that no SamyGo widget was present BUT all 237.4MB of 237.4MB were taken ! so I wasn't able to install anything else.
I then performed a Smarthub reset and fortunately all my apps were wiped out and smarthub memory released BUT when I pressed on the Youtube widget ,
smarthub wrote "updating app" and at the end , with my great surprise I found that an older version of Youtube was installed ! (different widget icon also !)
So my questions are:
- with this downgrade I have an old firmware before Cinavia implementation but the prize to pay is to keep an outdated version of Smarthub ?
- what have I to do to have SamyGo extension working ?
- in DSpExe patch wiki it is written that FW B-FIRURDEUC_001012 was succesfully patched but since the downgrade I performed reverted to 001003 FW release I am confused on the real alternative I have to keep my BD player Cinavia free, SamyGo extension boosted AND updated to latest Smarthub

Many thanks in advance for whom will help me to understand

Cheers
