I would like to replace the firmware provided by Linksys with a LEDE. So i downloaded the image file for my router from OpenWrt. And, i installed the image file on my router. However, i got an error message that is "the file transferred is not a valid firmware image".
Please provide the make and model of your router. It seems you tried to flash via the OEM upgrade screen in the web GUI. With some devices, that will not work.
I received "The image file is incorrect."
And i found one solution that if i get that error i have to change cfe boot loader.
Do you know something about this solution?
Wireless functionality is limited due to the Broadcom chip.
So instead of risking a brick on your router that may wind up not being as useable as you would like with OpenWrt/LEDE, you might stick with stock firmware, and consider another router.
