pin 10 trick would help you for sure.

Seem to have fixed it, I removed the wireless card, unit booted straitaway. Does someone know where to get a replacement card??

If you can't ping you unit or you can't access the unit via telnet or the unit is simply confused then you can unbrick the devices by following the instruction below:

WL500g Deluxe:
* open the case (screws are under the rubbers) (guarantee lost)
* turn on the router
* on the flash memory (29LV320ABTC-90) short circuit PIN 12 often (several seconds) to ground
* on the flash memory (29LV320ABTC-90) short circuit PIN 10 often (very short) to ground
* turn off your unit
* wait 10 seconds
* turn the WL500gP on by holding the reset button
* now, you can flash again via the ASUS-Recovery-Tool

WL500g Premium:
* open the case (screws are under the rubbers) (guarantee lost)
* remove the cover inside with a little screwdriver
* short PIN 9 or the marked solder point to ground (e.g. to the outside of the power connector) with a cable and a needle.
* turn the WL500gP on for approx 15 seconds.
* turn the WL500gP off
* remove the short circuit bridge
* turn the WL500gP on by holding the reset button
* now, you can flash again via the ASUS-Recovery-Tool

To use the full 32MB ram on the WL500gP use the following commands via telnet:

nvram set sdram_init=0x0009
nvram set sdram_ncdl=0
nvram commit
reboot

I made a photo for the PIN 10 trick. Here is it:

well, my unit worked perfectly, i wanted to setup an ddwrt in wl500g
with sp2 release

folowing instructions (first clearnvram,then restore and then ddwrt fw) i put clearnvram fw,and after that (i done it with restoration utility) unit won`t back from restoration mode.

whenever i power it, pwr light blinks (0,5 sec continously)

ofcourse immidiatly after power on, unit goes to 192.168.1.1 (pingable)

i tryed every method described on this forum or on the net (pin 10 trick),but after succesful flashing (on a restoration utility) unit won`t reboot,and when i plug it in, immidiatly goes in restoration mode

what to do?

Hi,

I cannot ping my WL-500g Deluxe. Power LED doesn't light, but the others LEDs do when cable is connected, adapter seems to be OK (voltage is 5V/3V on measure PBC points). Everything was OK till last week night storm.

I have tried pin10 trick and reset (20 seconds), but power LED has not light up.

Is there any electric scheme of board or testing (repair) manual?

Thanks for any response

[alegatorul]

Have you tried this ?

open case
id the pin 16..power should it be off,
put this pin to case negative,
keep it there connected,
power on the router,
still keep the connectors till the led blinks again as it were ok,
remove connector from pin 16 and U-
reset router,
install other firmware !!!

Good Luck !

does wl500g-recover.trx also works for wl500gx?

[Oleg]

Use wl500g-clean-nvram.trx to reset settings.
wl500g-recover would not work on deluxe

[cybero2912]

hi oleg thanks for the quick reply ;-)
at the moment I have DD-WRT on my WL-500gx but I want to change to your firmware due to easyer SMB/USB support. What would be the best way to change from DD-WRT FW to your FW?

[Oleg]

I've no idea. Never used DD-WRT.

The thing which should work for sure is flashing in the restoration mode.
