Editing Activation AFV

Only used by [[SKU_Models_Nonretail|Nonretail]], Kit Activation expires after 90 days, reducing several development functions of a TestKit/DevKit. The AFV file is a <abbr title="ps4_activation_&lt;YYMMDDHHMMSS&gt;.afv"> generated on request</abbr> by Sony and tied to console internal serial. An up-to-date console-tied AFV file must be sent to the PS4 using Neighborhood or USB to activate the console for up to 90 days. Once the PS4 has access to the AFV file, the user has to trigger activation by going to the [[Debug Settings]]. The PS4 OS then converts the AFV to an [[Activation ACF]] and writes that ACF token to the [[Serial Flash]] [[Non Volatile Storage]].

= Location =

(USB:)\ps4_activation.afv

The AFV file is downloaded from DevNet to a PC allowed to connect to such servers.

It can be sent to the console through a USB storage device or using Neighborhood and an ethernet cable between the console and the host PC.

= Description =

[[Neighborhood for PS4]], does not require any activation but an unactivated PS4 Dev/Test Kit cannot run fSELF applications. If the Kit Activation is expired, the PS4 shows the following message on the Main Menu: "''This Development Kit is Expired. See DEVKIT_Activation-Users_Guide.''" On later System Software versions, the message was changed to say "''This DevKit/TestKit is Expired. See Activation Guide on DevNet''".

= Format =

The Activation Key is a <abbr title="[length 8 string][hyphen][length 8 string][hyphen][length 8 string][hyphen][length 8 string][hyphen][length 8 string]">xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx</abbr> string (where x = hexadecimal).

The AFV format for PS4 is almost the same as the one for PS Vita.
