I thought we could upgrade to Tomato firmware directly from DD-WRT. Is that true? My attempts are failing. Am I doing something incorrectly? What are the proper upgrade steps? Thanks in advance! Code: Router Model: Linksys WRT54G v6 Router S/N: CDFD1FC... Current Firmware: DD-WRT v24-sp2 (07/22/09) micro - build 12548M NEWD Eko Want to flash: tomato-ND-1.28.5x-124-VPN.trx Initial attempt (failed): === Connected to router with ethernet cable (not WiFi), logged into router Went to DD-WRT "Administration->Firmware Upgrade" Selected "After flashing, reset to: Reset to Default settings" Selected "Please select a file to upgrade: /path/to/tomato-ND-1.28.5x-124-VPN.trx" Clicked "Upgrade" This resulted in the error message: "Incorrect image file."
