UserId permission error modifying SecSettings.apk in Android 4.4.2

[haplox]

Hello all,

I am trying to make some changes in SecSettings.apk in my stock samsung 4.4.2. When I install the new apk, I get this error in catlog

In packages.xml the new settings sharedUserId is referenced (as in AndroidManifest) in:

<shared-user name="android.haploxxx.system" userId="10007">
         <sigs count="1">
             <cert index="9" />

In package.list it is referenced in:

com.android.settings 10007 0 /data/data/com.android.settings platform 1028,1015,1023,3002,3001,3003

Some idea about how to solve this error? Thanks in advance
