1 - about itemInfo and 2018-01-24b, my repository only supports the latest client available and since the function changed in the more recent version its the only one supported, you can revert to an older version to use it or just replace the two functions in the end of the file with the old ones.
2 - about langtype 12:
* in sclientinfo.xml set the following:
<servicetype>brazil</servicetype>
<servertype>primary</servertype>
<connection>
<langtype>12</langtype>
</connection>
then go to "data/luafiles514/lua files/service_korea/externalsettings_kr.lub" move it to "data/luafiles514/lua files/service_brazil/externalsettings_br.lub"
(also better search for files with kr/korea in the name and replace it with br/brazil)
