First of all, I don't know anything about EEPROMs, or almost nothing.
I'm buying broken Kenwood double din nav units which they have a common problem, they never completely boot up, just keeps rebooting.
I have found a shop, which repairs these for a lot cheaper then Kenwood itself.
But I would like to find out how they do it, because I would like to be able to do it.
They, seem to replace a nand flash on the PC board.
The IC is a Toshiba TC58NVG1S3ETAI0 2GB nand flash chip.
Here is the datasheet:
What I would like to find out, what this IC does and if it holds the firmware or not?
I have replaced it with a new one and the receiver doesn't even boot up.
I'm guessing that it needs to be programmed to be able to boot, am I right?
If yes, then I would have to load it with the latest firmware?
The firmware, contains a CAB file, two ROM files and a bin file.
I was looking for a programmer, but I haven't really found one that works with the same exact part number, but it's pretty close. The programmer is an ELNEC brand, which it's way to expensive for this purpose.
Any input would be appreciated.
