i have a syslink wrt 1900 acs v2 router with openwrt firmware on it. I actually just want to get the original firmware back on the router so I copied the original firmware to /tmp folder on the router, but if i execute sysupgrade as described here
"Wrt1900acs v2 back to original firmware - #2 by valbon"
i just get the message "Image file not found". I also tried to flash new firmware image from luci but it just tell me "The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform."
I used the image found at linksys webpage for syslink wrt 1900 acs v2 router. (FW_WRT1900ACSV2_22.214.171.124002_prod.img) and as i can tab to select it I am sure that the image is present.
Please help me
