You could try again with TWRP.Great just what I was after, but unfortunately is doesn't seem to work for me
SGP511 Build 17.1.1.A.0.402. Rooted and unlocked. Root apps all seem to be working fine.
I booted into CWM V6.0.4.6, flashed the zip from the /sdcard and it says Install from SD card complete.
Rebooted and check system info and still on 17.1.1.A.0.402.
Tried again and this time cleared Dalvik cache and cache and sill the same.
Have I missed something?
