Hi,

my problem is that after uploading dd-wrt.v24_mini_asus.trx (ver 08-06-2019-r40559) to my WL-500gP-v1, booting hangs after "Mounted devfs on /dev".
Here is whole log from serial console.

So after reading UML hangs on boot after mounting devfs I double checked my router version and firmware version. I used correct versions.

For flashing firmware I followed this instructions and also Asus_TFTP_Flash.

What else I tried?
    clean up NVRAM with nvram erase and wl500g-clear-nvram.trx and wl500g-recover.trx

    I flash with tftp and "Asus recovery tool" and got same error. No matter which method same result.

    I also tried to flash with original firmware (WL500gp_1.9.7.7_TW.trx and WL500gp_1.9.6.9_TW.trx)

    I also try some other fws; Oleg fw, openwrt, freshtomato all with same result

    I compared flash adresses returned by CFE with some found on forum, they seem to be ok

    I came to conclusion that flash is probably damaged, althouth CPF always returned succesed message (this is from flasing original fw).

Hi

I bricked so many times my wl500gp v1, v2 and wl500w, so I Keep a wire solder to the flash chip pin. A needle is fine too. I use to short it to the fitting of the Faraday case covering the flash chip, or at one of the sma antenna connector.

You can try that:

https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=2507

But as I said, mine got bricked, last resource for me.
If yours is not yet bricked, try to find a less radical options 1st.

Did you check your power supply ? this b.... are very sensitive to bad/fail power supply.
