after reading a bunch of tutorials and postings, i made my own files with customisation version: 1279-6976_R3B
D5503_14.2.A.1.114_EURO LTE-nosystem.ftf (replaces D5503_14.2.A.1.114_Generic UK-nosystem.ftf) md5: e2e89972fc5eb19258c520bb8e10aa28
seems like some criminals found a new way to get root.
maybe their exploit could be used for something usefull, what do you guys think?
thanks for the offer, yes I might try it to see if my corporate Contacts/Calendar sync issue would still exist. They are breaking on KK for some reason - probably not a fault of Z1C ROMs (the same was happening on HD2). Not immediately as all work...
many thanks for the guidelines in this thread - and to TQuest for files in post #146 - rooted, TA backed up, bootloader unlocked. TQuest's JB files tested.
All this to try KK and find out that for now I am happier with Sony JB ROM, plus Xposed ...
