Samsung repp (sch-r680) boot loop/soft brick?! HELP!

[slimmbanditt]

I'm pretty new to rooting, and the android os in general but i did alot of research before successfully rooting my repp... then made the very careless mistake of repartitioning my system and sd card, which hasd my backup files stored on it... noiw im stuck in a bootloop.... i can still access downloads mode and cwm recovery, and have tried every method ive found in many forums on many sites, tho this model is not popular at all, it is a clone of the galaxy gio released somewhere in asia i think... anyway, i cant mount my system using cwm, i can't flash nandroid on odin or cwm recovery it always displays md5 mismatch error... if anyone can help i would appreciate it greatly.... ive been a week now without my android and im about to lose it... thx
