Re: I'v killed my 520GC
What is JTAG anyway?

I have never used JTAG myself. Afaik the most common uses are to re-flash the router in the event that the bootloader gets trashed, change flash/nvram settings, or use for debugging/kernel development.

Re: I'v killed my 520GC
Hi all
I have a bricked wl520-gu and i'm plannig to desolder the bcm5354 to find the JTAG pins, but i dont know what pins i must look for.
Anyone can give me further instructions? (schematic, or anything)
Thanks

Re: I'v killed my 520GC
Were you unable to get it into firmware restoration mode? Bricking the 520GU is almost impossible to do, unless you overwrite the CFE.
Re: I'v killed my 520GC
Yes.
I have light only on LAN LED-s.
I managet to put it once in recovery by shorting pin 9 to GND and flashing dd-wrt.v24-12548_NEWD_openvpn_jffs_small.bin.
After 5 minutes , power off/on but again LAN LED-s lit.
L.E.
I have bricked it by running:
"nvram set sdram_init=0x0009
nvram set sdram_ncdl=0
nvram commit
reboot"
