Hi: I have a WNR3500v2/U/L I have already flashed it to DD-WRT v24-sp2 (04/16/10) mini, and now want to go to Tomato. I assume the correct build for me is tomato-K26-1.28.9054MIPSR2-beta-Mini. I try to flash it, and it will not accept (wrong kind of file). I did some reading, and tried to rename the extension to .bin. Then, it accepted the file, appeared to start to upgrade, but "completed" in about 5 seconds. Of course, no upgrade, no change.
What am I doing wrong? Any help is greatly appreciated.
