There's a way to write to USB, according to https://4pda.ru/forum/index.php?showtopi...ry54536065

<item name="android.permission.WRITE_MEDIA_STORAGE" granted="true" flags="0" />

same goes for Kodi etc..

IT DOES.., finally!

Did it without ADB, just copied packages.xml to PC, edited it and copied it back to the box - rebooted.., and full USB write access granted

On my box now it looks like this:

<package name="org.xbmc.kodi" codePath="/data/app/org.xbmc.kodi-2" nativeLibraryPath="/data/app/org.xbmc.kodi-2/lib" primaryCpuAbi="armeabi-v7a" publicFlags="940097094" privateFlags="0" ft="1627693f1f0" it="161715762ee" ut="1627694263c" version="1799702" userId="10063" installer="com.android.packageinstaller">
