Damn. Apologize. This shouldnt happen.
What is the debug output on exlink cable? This may not help to revive tvs, w/o reflashing uboot and unlocked kernel before to flash exe.img , but helps to know what's wrong... No jtag howtos here. But if you're skilled you get support here.

If you set rs232 debug before to flash and your cable is working with proper pinoit, then you should see some debug info.
the treatment of this brick is used mainboard from sane tvs model, I don't believe the software way Is possible. Bad I haven't warned you before that this what we made was really experimental and can have such consecuences. Really sorry about that.

Re: Dump of UN46B8500 Need help/info
ok i have located the flash chip i think(PMC Pm39LV010-70JCE) data sheet http://doc.chipfind.ru/html/pmc/pm39lv01070jce.html
I can get to the WE,CE,OE,V+,gnd to solder with no problems.
what program can i use to flash my dump over and what should be the connections from the chip pins to the lpt port. like CE to what pin on the lpt and so on.
I have some experience flashing xbox 360 nands and dvd drive firmware so i am not tottaly in the dark.
any help or suggestions would be greatly appreciated.
Kevin

i think you'll need not just special program, also the firmware must be in OTF format.kpkev wrote:update after further inspection i determined that it was the wrong chip.

This is an image of the chips on the mainboard.
When I made the dump was there a special format it was done in or could I do a byte by byte rewite to the chip using the dump I made. I only flashed block 10. Could I rewrite just that block?
I also need to figure out the alternative pinouts.

you made the dump from linux vfs layer (at os level) this is totally other format as on the raw chip...kpkev wrote:http://img820.imageshack.us/img820/4779 ... 144247.jpg
