thanks for your reply
-HR does nothing since it did not work after installing a new ROM
-installing a new ROM could help, i did it indeed, the one that worked had a green screen in camera and i did not like it
-no repair is needed since it works
any other help, maybe some camera software to download?
-I copied files for camera from another working device but I could not replace the files in mine cause the files are READONLY, any suggestions?
I really appreciate your efforts, maybe my english is so bad that i did not explain it from the beginning.
