Ok i have solved the problem.
here is the way i use
:
1)For the PSTV device ID you can use any 17 numbers code for generating the liscence file PSM+.
2)After that start by a fresh install of the PSM for unity client ( i have formatted my memory card and backuped my PSM unity APP)
and don't launch it :
3) First do the first EML Tricks with the 4 elements in the first mail
Turn off internet connection and restart PSTV.
4) Launch the dev assistant it will tell you a network error press ok and close the app
5)Re-enable wifi and do the last EML tricks with the 2 file and launch the Unity APP.
At this step you must have no update message and it will display "no content installed" .
If not you must format your memory card and restart from the beginning.
6) Install Vitadefiler with smoke method --> bit.ly/1VEeb9J
use QCMA for transfer the file ( the CMA must show the correct size file 432 Ko and not 5Ko ).
Make sure you have no notifications and are not downloading anything and Rebuild the Database
7) do the update tricks and launch Unity app , at this point the app show me " Developper Liscence could not be confirmed"
8) Do the PSM+ once again and load Unity app it will now display the 2 applications :
"0000 "app" and "VitaDefilerClient" you can delete 0000
but when you launch Defielr it will show the Error
"failed the authentication to execute [the] application. Please re-create a Device Seed and App Key using...Unity Editor or Publishing Utility for Unity."
9) Just Close the App and Rebuild the database
10) It's all good now Ouf !
Thanks to Major Tom for help and telling me i can use any 17 numbers for PSTV liscence
