to be honest no i dont know what im doing with the programs its all a new learning curve to me thought it was strange though that in all 5 .bins the exact same blocks and locations were at fault any ideas on repairing them please as i have hit a brick wall and just stopped now . my head hurts please help lol . I have been following the guides from this site to the letter and im no stranger to soldering small components either .

bad block remapper says as per the picture 3 bad blocks modified

nand compare is saying "0 non-matching blocks found"

and hex edit says all 5 files are identical

many thanks for reply

you dont need anything from those sections, ignore the bad blocks and continue.

if you have problems getting xbr to boot then flash the bad blocks to the end of the nand

nandpro xbr.bin: -r16 xxx.bin xxx 1

nandpro lpt: -w16 xxx.bin 3ff 1

write 268 @ 3fd , 178 @ 3fe and 125 @ 3ff as degraded told you.
