hi where are you from ? i understand your english is not so good , I'm from istanbul and well aware how difficult it can be trying to translate/write in english, as the grammar does not always translate.
i would forget looking here for a solution only a few will take the time to help the others will just insult your intelligence and your original message will be buried in the "your not a dev" response.
if you were here in istanbul I would fix it for you in no time ,you need to do a bit of web searching but DFU mode is your path to the restore of whichever firmware you decide on. your iPhone is not bricked only bricked iPhones I have come across are physically broken devices.
what is your native language ?
