When trying to extract my NAND I get this error: "Data in block 137, page 21, plane 0 is corrupted. Unhandled Exception" Any ideas as to what might be causing this?
I had the same issue but at a different position. It means that your nand backup is faulty.
Well for me i THINK i fixed my backup.
This is what i did:
I had no clue how to calculate from block/page/plane to the hex position, so i opened up my nand in a hex editor. Scrolled into the middle position looked for a 00 and changed it to FF, saved the file.
Switched to cmd, redid the command and looked if the same position was corrupted.
If yes, your corruption is before that position: change the FF back to 00, save file.
Go to a position before the position you tried, by always taking half of the position you get it pretty fast.
It took me like 15mins.
If ibuild shows another adress, then you are before your corruption...
I had the luck that my error was in an area that was filled with FF FF FF FF ... , changed it and i was able to extract the files.
Bad explanation but i think you get what i mean.
greets
Now for my other console, whats wrong ?
Flashed freeboot, powered up, i get a single green light but no video/no error message.
I used the patched smc from the cygnos pack.
