ASUS died? No power led no failsafe mode...

I have a strange problem with my ASUS WL500g Dx

After flashing the firmware it's not just bricked. It seems to have died. The Power LED doesn't flash anymore (after pushing reset button) at all....

Could this be because I might have messed up the PMON?

Can I use JTAG to revive it?

Read the firmware upgrade tutorial and follow the links given in that thread. There have been other users who revived their unit by grounding a specific pin on one of the ic's.
