Nand error advise

[mousey01]

Hi all i am attempting a RGH hack on a 256mb jasper for a friend, i have dumped the nand 3 times using nandpro 3.0 using the commands NandPro.exe usb: -r64 nanddump.bin as Martin c recommended in one of his posts.
All three dumps kicked up error reading codes in block250 and about 7 other area a-f in exactly the same place, i compared all 3 nands using nandpro V3 and no differences were found between them. when i opened 360 Flash dump tool v0.95 i get the following information (as picture below), as i am quite new to this could anyone please tell me if this is standard or do i have to repair the blocks in any way? thanks for taking the time to read this and any help is appreciated.

never done a big block jasper before, so it's possible this is normal, but I would try to get a clean nand dump. check your wires (lpt or nand-x or whatever your using) and make sure they all have good solder points, then try to redump and see if you get the same bad blocks.

Proceed with the RGH. Only remap bad blocks if it doesn't work.

Remap bad blocks and rebuild the ecc image.

If problem still persists try using Multibuilder v2 instead of v3
