FF it is
However the starting address of the block to be overwrited seems to be different from other files posted in this thread which makes me somewhat unsecure about it. This is the code:
# Pyton script to fill block [d1-d2] of a binary file
with the same byte value
# Start and end addresses:
#d1=226770
d1 = 226824
d2 = d1 + 1204
# Byte value
BYTE=b'\xff'
import mmap, shutil, sys
path = sys.argv[1]
splitpath = path.split('.')
newpath = splitpath[0] + '_unlocked.' + splitpath[1]
shutil.copyfile(path, newpath)
with open(newpath, 'r+') as f:
with mmap.mmap(f.fileno(), 0) as m:
print('working ...')
m.seek(0)
for j in range(d1,d2+1):
m[j: j+1] = BYTE
print(j)
m.flush()
m.seek(0)
f.seek(0)
print('\n Done.')
# End
