Bad Blocks?

If bad blocks were found while dumping your NAND...



Open one of your NAND dumps in 360 flash dump tool 0.97

Don't worry if it says BADKV all over the place, this is normal because you haven't entered the CPU Key yet. (We will get to that later).

Check for a bad blocks tab, next to the file system tab.

If there is no bad blocks tab, you have no bad blocks.

If there IS a bad blocks tab, click on the tab and verify that it looks like this:

Note: Bad Block ID 0x0349 [Offset: 0x00D8D200]

-> Block ID 0x0349 found @ 0x3FD [Offset: 01073A00]


You should see the above 2 lines of text, for each bad block you have.

The numbers may be different of course, depending on which blocks are bad, but the point is, for each bad block, you should see that the block was found @ another block.

This means that you did have bad blocks, but they have been corrected by the NANDs error correction, so they are legit bad blocks, and not just read errors due to dodgy soldering.

Example of 3 corrected bad blocks...



If the errors are at block 0x50 or above, no further action needs to be taken, because…

"Many user reports indicate that using Xell-Reloaded/Rawflash v3 to flash the Dashboard image, has a much better result over flashing with hardware flashers. This is because it helps to auto-remap the bad blocks in case they exist."

As we will be booting into Xell-Reloaded, which will use Rawflash v3 to flash the NAND later on, the bad blocks will be auto remapped for us.

But...

If you see:
Note: Bad Block ID 0x0349 [Offset: 0x00D8D200]

But NO found @ location for the block, that means this bad block was the result of a read error with the NAND reader. Check your soldering and try again.

If you have Bad Blocks at 0x50 or below, check out Martin C's guide on how to manually remap them. (Info)

If all checks out, you now have 2 good NAND dumps.

KEEP THEM SAFE. FOREVER.
At This Point ,He Showing ,He found bad blocks,If i found any blocks,how repair them ? is flash dump tool automatically repair them or i have to dump nands from my motherboard until i have the good nand without any bad blocks ?

Dump nand twice and compare them, they have to match with or without bad blocks.

Bad blocks are usually not a problem. Multibuilder automatically remaps them for you.

If you got bad blocks within the first 50 blocks follow MARTIN C's guide

That means ,if i got bad blocks under 50 blocks & my 2 dumped nand match ,i don't need any thing right ,just put one of my dumped nand to 360 multi builder and write the glitch image to my nand(or motherboard whatever) ,it should be fine ?

you need to check if its already a remapped block the system sorted out, if it is do nothing, if its not remap before you write the ecc or it will fail.

to save this back and forth where do you have bad blocks and what did 360 flash tool say about them?
No ,i just being ready for this...

So any one can give me those the error codes(like fid3r's |Error : 250 reading block FF
Error : 250 reading block 200
Error : 250 reading block 29d
03ff ) who needs to be remapped(Please) !

error 250 means bad block. as long as they are not in the first 50 you can use multibuilder to make your ecc and rgh nand and they will remap automatically. same when you use xell to write the new nand.

without meaning to be rude mate if you cant follow the guides your never going to be ready for this. its not even a concern in most consoles so just read the guides and follow what they are saying as best you can and deal with it if this ever comes up for you.
