I know, manually deodexing that way would cause a bootloop because of missing classes.dex files in every system app.
Some people that dont like the preinstalled Sony apps prefer getting rid of all the bloat and remove SemcGenericUXPRes.apk from framework folder.. And some (or most) of the framework jar files beginning with "com.sony..."
This will of course bring noticeable smoothness increases, but is very likely to cause bugs when not done by experienced users.
And it could cause a bootloop on odexed builds as the odex files in system/app do no longer fit to the framework.
Just for information.
I don't suppose someone somewhere has listed which of the com.sony*** files are safe to disable have they?
