so my friend told me that i could root my phone (samsung galaxy legend) by using the Galaxy stellar root. tried it, and it said failed. so i got out of downloading mode and it started by loading up normal but said something like .android stopped working every 2 seconds. so i tried to factory reset to fix it. now it loads up like a stellar, and wont do anything because i dont have a sim card which my phone has no slot for it anyways. so how do i get my factory samsung galaxy legend software back on the phone so i can use it again??
