How many bad blocks have you got??

what's the exact errors what do you get when you extract an interleaved image?

Bad blocks are placed in the next available free block

Am not sure on it with it been a brick

Any chance you can upload it and send it to the dumpcheck email
But put its for sarah1331 as requested

Much of the extracted data is missing (from the .ext folder) and what is there has corrupted filenames - I think beause some headers are corrupt in the dump but I think this may have been the work of the downgrade gone wrong - could also be the bad block though.

I've tried with a 60GB nand dump to inject the data as per my post, and it gets a little further but the 60GB console dump says it had bad blocks too.

Is there any tools I can use myself to check the dump? Like I can use HxD to check it manually and extract data etc, but I'm not 100% sure where everything is located - like all the files that flowbuilder pulls out - is there documentation as to what it looks for and where it pulls it from?

I know a lot of the OS stuff is corrupt in the dump. I can upload the dump file to my dropbox public folder and shoot you a PM?

My NAND 0 had 1 bad block.

Ill take a look for you but one bad block is not going to do much damage IMO

I had a CECHA that I downgraded. 1 Nand had 0 bad blocks and the other Nand had 3 bad blocks. I kept dumping and dumping and always got the same. So I asked eusnl on irc, and he told me that it is normal. That nands come with bad blocks from the factory and I should not worry about so few bad blocks.
So I patched and flashed, and downgraded. It was the only Nand model I have been successful with. :/
I have been using the 360 nand clip with ProgSkeet v1.1 to try. I need to either modify it more, or get some time to practice soldering. Getting better at soldering, but some of them alternate points are so tiny. LOL.

Bad blocks are ok it just depends where they are on ps3

I have done many consoles with badblocks but if there too many or in the area where data is needed florebuilder throws errors

So little off-topic, but first... long story short. Friend of mine just gave me CECHG fatty PS3 with 4.21 OFW. From what I have been read so far, inside of it there is two SAMSUNG K9F1G08U0B NAND's. Right? So...if i dump the two nands ( de-solder them, read them with my own prog) can I flash the dump back to HYNIX NAND H27U1G8F2B for example OR the PS3 will recognize diffrent vendor for the nand's and halt it's self?

p.s. The idea behing all this is to protect the PS3 from turning on to a complete BRICK if something goes wrong either when flashing or when manipulating and patching the dumped BINs.


Excuse me for my bad english...

Till now i downgraded only one NAND PS3 and luckily there was no Bad Blocks;
so what you are saying @Sarah1331 , i should not worry about Bad blocks as long Flowbuilder did not throw any arror, or i shall go and solder the ALT points for the NAND Mobos and try soldering option

Ok - update. I had a look through the flash file and it seems to be all good other than the the core OS and the flash region table.

The flash region table was a mess - corrupted headers, wrong count, wrong size, and then wrong offsets and sizes for the various files.

I rebuilt the table manually, and replaced the coreos regions using the patch files in the foolproof downgrade guide.

I also took my good nand file (nand 1), and copied it out to F0.bin and F1.bin, then rescrambled my patched firmware to these 2 files.

Once completed, I unscrambled them out again with flowrebuilder :

No bad blocks :-)
All files extract ok :-)

Still not 100% sure if they really are ok but they look ok to me from the guides I've found. I then flashed my 2 new clean files to the Flash0 and Flash1 NANDs and popped them in the sockets on my SEM-001 and turned it on........

Green light of death - LOL. Progress???

Previously I had YLOD (well, green light, yellow light , it beeped 3 times or something and shut off with red light.

Now it gets a solid green light, but no video and no power to the USB.

Any thoughts??

Sarah1331 - I can upload the new files if you'd like to have a look? I'm not sure what method you use to verify them.

Yep - you can desolder them and dump them then solder them back ok - I wouldnt worry about flashing to another vendors chips so long as you have the dumps that is all you need. Also I'd love a copy of that dump if possible as it may help with mine!

What happened to the Other NANDs you downgraded
I would not worry about Small Solder point, do you have any skills in modding PS2s? if yes you will be OK

@deanclaxton
Tomorow when I chek the programer if it is capable to read/write the NAND, I will contiune the experiment with just flashing the original DUMP to diffrent vendor and power on the console
