Iphone 4s recovery

So my iphone 4s was stuck in recovery loop. and when i tired restoring i would get error -1 or when i restored with dfu got error 21 then i tried plugging into redsnow and recovery fix it said the short version of recovery fix has been done to your phone, the long version is not available for the 4s. so i tried turning it on after that instead of going to plug into iphone it would show white apple logo then turn off and itunes didnt recognize then i put it into dfu mode and restored it and then when its almost done it turns onto apple logo then turns off after like 3 second and it keeps doing that thats where i'm at.
