No successin debricking 500gx

[eLv]

Hello all,

after playing with nvram sdram_* settings my 500gx doesn't boot anymore. The powerled stays off and I cant make it enter failure mode.
So I opened it and looked for PIN 10 (A20 on chip MX29LV320) and tried to ground it by touching it with a screwdriver as described at http://voidmain.is-a-geek.net:81/redhat/wrt54g_revival.html but had no success. :(
Is there someone with some additional suggestions? Does it makes sense to try to shorten A17 AND A18 ?

Thanks for the attention

Ok nothing, success :)
tried to short to ground PIN10 to GND of J5 (top left corner, near the leds) for a couple of times did the trick :)
