How to fully block YouTube from being updated on the PS5 when using YT2JB.

Full-Y2JB-YouTube-Block.md

Simply modifing appinfo.db will not block YouTube from being updated. As soon as you connect to the internet without setting a DNS it will automatically refresh itself to the correct clean state, the icon also switches back to original. This can result in a softlock where you have to set up everyhting again.

In order to properly block YouTube from being updated, you also need to fully update YouTube's parameters after a new installation.

The param.json file of the YouTube app is actually located at 3 positions when installed :

• At /system_data/priv/appmeta/PPSA01650/param.json
• At /user/appmeta/PPSA01650/param.json
• And also inside /system_data/priv/mms/app.db TABLE: tbl_contentinfo COLUMN: AppInfoJson
  • The values aren't exactly the same ones as in param.json but the CONTENT_VERSION and VERSION_FILE_URI is also located in there

To fully block YouTube from being updated:

1. Get /system_data/priv/mms/appinfo.db and apply following patch :

UPDATE tbl_appinfo SET val = 'http://127.0.0.2' WHERE titleId = 'PPSA01650' AND key = 'VERSION_FILE_URI';
UPDATE tbl_appinfo SET val = '99.999.999' WHERE titleId = 'PPSA01650' AND key = 'CONTENT_VERSION';

2. Get 1 param.json from /system_data/priv/appmeta/PPSA01650/param.json OR /user/appmeta/PPSA01650/param.json
3. Modify contentVersion to 99.999.999 and versionFileUri to http://127.0.0.2
4. Get /system_data/priv/mms/app.db and apply following patch :

UPDATE tbl_contentinfo
SET AppInfoJson = json_set(
    AppInfoJson,
    '$.CONTENT_VERSION', '99.999.999',
    '$.VERSION_FILE_URI', 'http://127.0.0.2'
)
WHERE titleId = 'PPSA01650';

5. Navigate to the Settings on your PS5
6. Upload all files back using FTP :

• param.json to /system_data/priv/appmeta/PPSA01650/param.json AND /user/appmeta/PPSA01650/param.json
• appinfo.db to /system_data/priv/mms/appinfo.db
• app.db to /system_data/priv/mms/app.db

7. Press PS button on the controller and restart the console

And app.db with that code is adding new parameters instead of overwriting:

Original extracted from PPSA01650:

{"data":"01.000.003","key":"CONTENT_VERSION","size":10,"type":2} {"data":"https://sgst.prod.dl.playstation.net/sgst/prod/00/np/PPSA01650_00/c91127c5-5b92-4a2a-83b4-0bc41481f672-version.xml ","key":"VERSION_FILE_URI","size":255,"type":2} ,"mimeType":0,"mimeTypeFormatVersion":0,"parserId":0,"promoterFormatVersion":0}

With your code (extracted):

{"data":"01.000.003","key":"CONTENT_VERSION","size":10,"type":2} {"data":"https://sgst.prod.dl.playstation.net/sgst/prod/00/np/PPSA01650_00/c91127c5-5b92-4a2a-83b4-0bc41481f672-version.xml ","key":"VERSION_FILE_URI","size":255,"type":2} ,"mimeType":0,"mimeTypeFormatVersion":0,"parserId":0,"promoterFormatVersion":0,"CONTENT_VERSION":"99.999.999","VERSION_FILE_URI":"http://127.0.0.2"}

It is not overwriting the values, instead is generating new ones added at the end, and i don't know if it is intended? I used this (not tested on PS5, but checked on pc):

UPDATE tbl_contentinfo
SET AppInfoJson = json_set(
    AppInfoJson,
    '$.field_list',
    (
        SELECT json_group_array(
            CASE
                WHEN json_extract(e.value,'$.key') = 'CONTENT_VERSION'
                    THEN json_set(e.value,'$.data','99.999.999')

                WHEN json_extract(e.value,'$.key') = 'VERSION_FILE_URI'
                    THEN json_set(e.value,'$.data','http://127.0.0.2')

                ELSE e.value
            END
        )
        FROM json_each(AppInfoJson,'$.field_list') AS e
    )
)
WHERE titleId IN ('PPSA01650','PPSA01651','PPSA01652');

With this code you get this:

{"data":"99.999.999","key":"CONTENT_VERSION","size":10,"type":2},
{"data":"http://127.0.0.2","key":"VERSION_FILE_URI","size":255,"type":2},
,"mimeType":0,"mimeTypeFormatVersion":0,"parserId":0,"promoterFormatVersion":0}

You are probably in the wrong database. The JSON is also wrong. It will look like :

You are showing me appinfo.db, not app.db (they are stored on /system_data/priv/mms/, as you said). appinfo.db is using table "tbl_appinfo", but app.db is using "AppInfoJson". Please, recheck.

appinfo.db was adressed on my first post, you corrected it.
