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?

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.

Thanks for the information. I am doing this to test wifi speed using OEM over dd-wrt. As I stated earlier, wifi speed is about 1/3 of my ISP router, but dd-wrt gives me much more control over my network that I like. I'll post if the instructions worked.
