Linksys router is on stock firmware v184.108.40.206977
Trying to install LEDE firmware downloaded from here:
I am getting this error: "This firmware file won't work on this router. If you downloaded it from
Iinksys.com it might have become corrupted. Please try downloading the file again."
I tired downloading again and the same error. I did do a checksum of the file and it was matching.
Btw I also tried to downgrade the router to stock v220.127.116.11978 and I am getting the same error. The only file that is not giving me any error is the latest stock firmware v18.104.22.168977.
Looks like its on a locked firmware from version 22.214.171.124630. Need to get a USB to TTL cable for loading other firmwares:
Now thinking whether to return it and get something else or buy the cable!
Get the firmware past a certain point. I tried it on 1.1.5.x and it worked fine. This guides says to get it to at least 126.96.36.199978 .
I am on v188.8.131.52977. Another post talking about the same issue:
The router won't allow me to downgrade to v184.108.40.206978!
Try downgrading to one of the 1.1.5.x OSes. If nothing else, there are instructions on the page I linked tell you how to do the other ways if the easy way doesn't work.
I managed to implement mrjcd's instructions that OP mentioned above on one of my two EA8500 routers, but I replaced the stock firmware with DD-WRT (as did mrjcd), and implementing those superb instructions was a pain; I did this before I discovered LEDE.
I'm guessing the same procedure would work with the LEDE firmware instead of the DD-WRT firmware, but have not tried this yet.
Hope this helps.

Unfortunately my brand new EA8500 arrived today and the stock UI firmware upgrade refuses to allow the factory .bin for LEDE. The unit arrived with firmware 220.127.116.11728. SSH isn’t offered as an admin option. Downgrade to firmware 18.104.22.168978 also fails (invalid firmware file error). Does anyone know whether a TFTP update bypasses the firmware version check?
