I don't know the difference between N810 and N900. But I indeed bricked my N810 by doing
warning: please don't try it, if you don't know for sure.

Code:

dd if=/dev/zero of=/dev/mtdblock0
dd if=/dev/zero of=/dev/mtdblock1

/dev/mtdblock0 is for bootloader
/dev/mtdblock1 is for config

Now there are nothing show on screen when do firmware flashing or firmware cold flashing by using USB.

I know there are Serial Console connector under the battery which perhaps can be used for cold flashing.
TTL level converter is needed and tools to access pad connector also needed. I have found this

I haven't try to unbricked it because I haven't bought these tools.

Under Nokia label, other pad connectors can be found perhaps for JTAG port. But no function for each pad connector can be found.

N810 don't have ROM/BootRom let user choose booting from NAND or from MMC/SD, when all code on NAND is zeroed, it will be bricked. That's all I know about this situation.
