the installation for the new rom worked fine but when trying to modify dpi in /system/build.prop a got a message for no access
I run root checker and verified that phone is not rooted
baseband version is I9100JHLS2 and build number is Slim_i9100-userdebug 4.4.2 KVT49L 4068 test-keys
How can I root it againg? Thanks!
