Given binary have a lot of "X"'s in it. In order to find correct binary, combine fragments data and replace with those X's.
Bruteforcing all options. 
```import itertools
f = open("broken")brokendata = f.read()f.close()
	head = 0x5adtail = 0x8d4
brokenhead = brokendata[0:head]mid        = brokendata[head:tail]brokentail = brokendata[tail:]
fragments = []
for i in range(1,9):    s = "fragment_" + str(i) + ".dat"    print "Reading " + s    t = open(s,"r")    data = t.read()    fragments.append(data)    t.close()
print fragments     
x = [1,2,3,4,5,6,7,8]
perms = list(itertools.permutations(x,8))
print "Perms created size : " + str(len(perms))
dat = ""
