just fyi..take no credit here
I followed this link (posted on another thread in a message but maybe did not get much press for whatever reason)
got it from here (thanks Blacklist)
credit to whoever created the zips at this link
use google translate..
see the c6833 section (guess similar process for other variants as they seem to look all similar)
got the full rom flashable zip and the deodexed zip...
not note: was on unlocked bl...had earlier tried the odexed full rom using jackie's kernel and recovery rooted and the ftf
so i did full wipe flashed the odex flashable zip..
also before booting, flashed after that the installer for dual recovery (philz touch cwm and twrp) and su install zip..after su binary update and reboot full root was there
then went to recovery flashed the deodexed zip (which is like 1/3-1/2 size of the full odexed)..
booted...all set up deodexed and running...mms, sms, calls, internet work
also xperia xposed has now a call recording module (call it Xperia dialer mods which works only on xperia stock/stock-derived rom not cm-based/aosp)
in call, you have option to turn on recording..works perfectly
