It could be that your ProgSkeet v1.2 isn't working properly?

IMHO 100% best method is to remove NAND, solder onto NAND adapter PCB etc. etc.

I will soon be releasing a service to take peoples v1.2's and convert them into WORKING v1.1's on what I hope will be a much improved PCB over the original.

This information should not be overwritten by the PS3 - so it's probably there as well. can you validate this? I don't have yet a NAND w/ bad blocks to check this out but i will be happy if you can go over all the valid blocks and see that the first byte of the spare area in the first page is non-zero unless it's a bad block. a page is 2112 bytes long (multiply it by 64 (number of pages in a block) and you get 0x21000) and the spare area is beginning after the 2048bytes of the block. so offset 2048 in each block should be non-zero for a valid block and zero for a bad block. I will be happy if somebody can confirm/verify this (or send a link to a dump w/ a bad block) - so that i can integrate it to my code.

Sir

i just want to tell you something,before 2 days i was going to downgrade sem-001,i did alot of that mobo with 0 badblock,2,3 ....etc all were OK,,but this time bad blocks were 11/each dump,total = 22 and the console failed to be downgraded with 1patchcos and 1patchcos3.55,so i decided to replace tsops from known cok-002 and both checked with 0 bad block..

after soldering and reflashing the replacement tsops ,console started up fine,then i updated the console with OFW higher than ever,NOW reconnecting progskeet to dump both tsops on the hope i will get 0 bad block /each.........OMG,i have been shocked,the same 11 bad block are also reported by flowrebuilder and nothing changed....

so i am assured now that the bad blocks came from errors while writing tsops and not from the tsop itself and my question is ;where is the problem? CPU ? southbridge? CXD9909GB ?

When you write your dumps from the NANDs with bad blocks you copy the bad blocks over

Eg block 3 is at block 9 ect you just copied this not remapped them

i said that i updated the console to OFW higher after installing the replacement tsops,will the southbridge skip the badblocks i wrote from the original dumps?

Updating wont do anything as it stil says 000000000 in the blocks that was bad so it will skip them

thank you for sharing your mind,i am assured that the southbridge won't skip those blocks because they are not physical bad blocks

overall,what do you suggest to handle this issue?there are 11badblock/tsop and console doesn't accept downgrading

Remap your bad blocks and flash to good TSOP's and try if it works start downgrade process again

both original dumps are remapped,written back to the console,i got ylod

Not remapped correct
