Watchdata EMV chips in R6, G0 and other cameras

[Purduephotog]

I've not used a smart card reader with these devices. Much of what is stored is available via the prtHardInfo command in psh.
And attempts to write could trigger the self-erase protection.

I figured all the easy approaches would have been taken already.

*sigh*

-very irritated at this product for being mis-advertised.

Most of the stuff on the emv can be bypassed from davinci anyway.

Ah, but see, I'm still looking for that little lever way in.

The NAND flash reader is on order.

OK so I have desoldered the RAM chip and dumped it. I have purchased a programmer (i need to get a swapped one) and a solderable 'socket' to put said ram chip in. Going to grab a few more of the same spec chips and burn the same FW to them.

Almost there....web page gives:firmware language mismatch: /dav/webLib
Something is missing but what...?

Hi, can you please tell more details about how to modify the hex bytes from the EMV chip? I can read and modify the hex data from 0xC061682C using the command "mb.w". I tried to add this command to bootargs, but nothing changed after camera booted up

Thanks
