I have done the same things with my galaxy mini 2 in the same way and i didnt have any problem with it (kitkat works there propely).
Could you help me to fix it? what should i do, i heard that i should install JB via Odin then root again and update CWM but im not sure about it.
Hello, I have problem with CWM, i have rooted Galaxy Ace 2, then i wanted to update recovery to CWM 184.108.40.206. but my Odin Failed in conection. I decided to unplug phone and then i realised that i see only statement "Firmware upgrade encountered an issue. Please select recovery mode in kies & try again" (I could go only in Download mode). After long time i found a bit older CWM, 5.x.x it worked but it doesnt support kitkat. I wanted to update it from SDcard to 220.127.116.11, it has beed installed successful but when i reboot it again to recovery it was still same old version.
