Hi I trying to upgrage Linksys EA4500 v1 from 19.7.6 to 21.02.0.
The first thing that I learned/did was :
I need to force and use a factory image ( When I used sysupgrade image with my netgear_wndr4300 I bricked it and needed recovery with Tftp2.exe )
Not choose to keep the old values of setup ( Wi-fi, network, ddns ... ), upgrade to a new and clean installation
But the thing is:
Using the image openwrt-21.02.0-kirkwood-linksys_ea4500-squashfs-factory, the instaler ask me to force the upgrade because it not recognized like correct image.
Even forcing to upgrade using this image nothing happen, the router bricked and I have to start with reset button pressed and the router return to the old version of openwrt ( openwrt 19.7.6, how this happen? This modem have two flashes like two bios in same motherboards? )
So I'm stuck in this point.
- How can I make this work?
- How can I force this model to enter in Tftp server state to I try to force write the image using tftp2.exe?
Thanks for your time!
