What do you mean
download a rom and just flash it that's all
You don't have to do clean flash cuz you had already do that

Flashed Cache, Dalvik Cache..
Tried to flash the rom many times but cudn't..
n There's no response from Seniors...
I've not gone back to stock so have no advice, what I did find some months ago was that the Rom I was trying to flash was corrupt.
You sure the download is OK?
sent usin' tapatalk innit.

Download the firmware from sammobile for your country and flash it with ODIN
I recommend you to wipe data before and after the flash

DO NOT EVEN TRY TO USE "NAND ERASE ALL" that would be pretty bad...
yes you can switch back to 4.1.2
