I am using Samsung Galaxy Grand GT-I9082 from past one year. I got lot of software updates and did all of them, including the 4.2.2 JellyBean FirmWare Update.
Recently I got one stability update, after which my mobile lost it's stability. Now I want to revert back to Jelly Bean prior to that update, by re-installing 4.2.2 JellyBean FirmWare. I have read few blogs about the procedure with Odin but I am confused whether that procedure only works when my mobile is loaded with 4.1.2, or with any version? Currently I am using 4.2.2 Jelly Bean.
I have tried hard reseting the device and wiping the cache partition; but still the device is slow, constantly hanging sometimes, and I am missing important calls also.
