Download the ETSI (European) or US version of the firmware for the router. We use the ETSI version
wget http://cache-www.belkin.com/support/dl/FW_WRT54GL_4.30.17.011_ETSI_20150623.bin wget http://cache-www.belkin.com/support/dl/FW_WRT54GL_4.30.17.011_US_20150623.bin
If it is a bin file convert is to a trx file
dd if=FW_WRT54GL_4.30.17.011_ETSI_20150623.bin of=FW_WRT54GL_4.30.17.011_ETSI_20150623.trx bs=32 skip=1
Unlock the router and check which name to use (linux or firmware)
mtd unlock linux
This should result in
Unlocking linux ...
If not try
mtd unlock firmware
Which should also result in
Unlocking linux ...
Load the firmware. If unlocking with linux did not work use firmware
mtd -r write /tmp/FW_WRT54GL_4.30.17.011_ETSI_20150623.trx linux
Results in
Unlocking linux ... Writing from /tmp/FW_WRT54GL_4.30.17.011_ETSI_20150623.trx to linux ... Rebooting ...
