I recently acquired a Linksys MR9000. I installed DD-WRT and now would like to go back to the Linksys factory firmware. In setting up and troubleshooting DD-WRT, I believe I wrote DD-WRT to both partitions.

I have tried to upload the OEM Linksys firmware through the webgui once and twice in a row in an attempt to write both partitions - but no luck it still reboots to DD-WRT.

I have scoured forums and have yet to find a way back the Linksys firmware. Am I stuck? Is there a way to do this with SSH or another direct connection method?

thanks-

Like the original poster, I have tried to restore the original firmware. However, going through the dd-wrt ui and uploaded the firmware still results in dd-wrt being present on the router.

I find the wifi speeds on the router are about 1/3 the speed I get on my ISP router. I'd like to swap out the ISP router with my router, but the wifi speeds I am getting, with dd-wrt, are not acceptable. Wired speeds via the mr9000 are fine.

The tech specs for the CPU are:
CPU1 check Qualcomm IPQ4019
CPU1 Type ARMv7 Cortex-A7

My understanding that a 30/30/30 reset is not advisable since this is an arm processor.
I have booted both partitions and bot have dd-wrt on them.

Any guidance would be greatly appreciated.

It's probably the same as the rest of the Linksys MR/MX/EA 802.11ax devices recently added. SCP the OEM firmware file to /tmp and then figure out which partion you're booted to and write the file to the opposite partition and then switch boot partitions. You should also be able to write to both partitions while booted to DD-WRT, but YMMV.
