Hi friends.
Long time reader, first time poster.
I was experimenting with my Hikvision DS-2CD3145F-IS (Which I think roughly equivalent to the more popular DS-2CD2142) .
I managed to corrupt the mtd0 partition on the NVRAM that contains the u-boot program which runs at boot.
Now when the modem is powered up there's no response on the serial port and no activity on the Ethernet port.
I've tried holding down the reset button for 10 seconds after powering up, but I suspect that only helps in cases when uboot is intact.
Any ideas?
If not then can someone with experience get me started on how one goes about manually rewriting a NAND chip? Is that an avenue worth pursuing or should I just make this camera into a door stop.
Thanks very much everyone.
P.S. I can't thank everyone on these forums enough for all I've learned about reverse engineering, linux, u-boot and all sorts of cool things.
