Error 250 reading block 1

[cheezy102]

I'm on my 3rd JTAG install now and having some problems. Have dumped the nand and checked with nandcompare (0 non-matching blocks) but I receive the same error every time I dump the nand.

Error: 250 reading block 1

I did a search and found that this is the kv and that I needed to find out where it had been remapped to in degraded. But when I try to open the file in degraded it says it could not open.

Any help would be appreciated!

open the file in xnand healer or 360 flash tool and these will also tell you where the bad block has been moved to.

Ok I have opened the nand in the "remap bad blocks" section of Xnand Healer. Can I just load the original dump as a template and then load in my freeboot nand image?

 

[BGAMods]

i only use xnand healer to check where the blocks are located then manually remap them with nandpro in cmd prompt.

I take it this is one is made after 2005? Probably a HDMI as well?

You can always make a copy of your nand dump, load it into a HEX editor and change the bit that says 'Microsoft corpration 2004-200' to 2004-2005. Then you can loaded it into degraded. Probably cause who ever wrote degraded didn't plan beyond the xenon boards line.

You can also use nandpro to remap your bad blocks, once you got used to it, nandpro even allows you to remap blocks directly to the NAND on your console without the need of reading a whole NAND and writing it back.

Compile your freeboot first and install it and see if it works or not, you don't have to remap automatically just because there are bad blocks.

ive only ever bothered to remap once before. i dont normally bother.

What board was that on? Doubt it had SMC alt point?

 

[BGAMods]

it was on a xenon.

Thought so, those xenon boards take about anything you dash to them except for the dreaded RROD.

I got that Falcon board you mentioned a while ago from Matt with bad flash to the DVD, had 1 bad block 3FF. Had to remap for both xell and freeboot. To add to my trouble after done everything and testing it late night, it decided to give me E74 . I revived it this morning but god knows how long it will last.

Thanks for the help guys. It a non-hdmi xenon. December 2006. I flashed xell to get the cpu key to make my freeboot image but got e79 error. Checked all my solder joints with a multimeter and they are all good. Any ideas?

 

[BGAMods]

did you remap block 1?

 

[cheezy102]

Flashed back to original dump and boots fine

You can take remap the xell bin files for your xenon board and try them again, if that doesn't help either then it's most defenitly a soldering issues.

Go to 'C:\Program Files\Jtag Tool\Xell Bins' and use the file xenon.bin with nandpro to remap the blocks then place it back in that folder and flash it your console.

If you post me a screen view of your bad blocks and where they are, I can write you the exact commands to extract the blocks and then write them back to the bin file.

did you remap block 1?

Here is what I did. I am trying with XBR now. I extracted config from original nand block 3de and wrote it to xbr.bin block 3de. I then extracted the kv from block 3ff (thats where its remapped to) and wrote it to xbr.bin block 1. I then remapped block 1 to 3ff.

I have checked the joints with a multimeter and they are good.
