Nothing weird, security goes up. Developing new roots takes more and more time and requires more and more skill Also sneak peak (due to API differences) probably first thing released will be K bluray root, later K tv root and "sometime" this year new H root (if all goes well ). H bluray root is almost ready but we lack testers, so can't do much about that No idea how to tackle newer J yet (it lacks API ).
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on http://ctrlv.it/ Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!
