So gent's is this a dead issue for the 9500, with LEDE being the only option via serial cable?

I am also wondering if there is any hope. I love my network speed and the propagation with this router, but I need DD-WRT. Is there anything that can be done?

I did install LEDE and it seems to be working fine

The serial cable installation was pretty straight forward similar to the EA8500 with newer stock firmware. I read about here:

So very unfortunately, there will be no possible way of getting ddwrt on to the Linksys EA9500. Although we have developed dd-wrt for it, it will not be able to work as the firmware for both the models (v1 having a dual core broadcom northstar cpu. And v2 having arm 64 quadcore cpu) are encrypted and signed via pgp. A sad day indeed Sad

I don't understand how LEDE gets around this. Does LEDE have access to signed/encrypted firmware?

I hope there's been some movement on this. In the OpenWRT forums they've managed to use the header of the linksys firmware with the OpenWRT firmware to be able to upload it directly from the Linksys UI. I'm sure DDWRT can be uploaded the same way.

If there's any build for EA9500 v1 I'm willing to upload it through serial to test it out and can share any files needed.

Hi guys

I have a Linksys EA9400 v1, can I use the DD-WRT firmware of EA9500 to flash for my EA9400? Will it work? Thanks

EA9500 is not officially supported by DD-WRT AFAIK.

"TBD Donation Router Needed"

Donate a router and/or do the homework and submit to the developer:

i still have no hardware details about that device. if its broadcom, send me a nvram and cfe backup. thats all for the beginning and i can find out more of it. if its something else, i again need more details

This is the homework you need to submit to Brainslayer.

I don't know the secret sauce of coaxing this info out from a router because there is some trickery involved in saving the files when they're copied. and it's not a one size fits every router deal...

I'd be happy to update the cfe wiki with more details, but you can start there.
