[edit] Preparation

Current EA8500 stock firmware (since 1.1.4.168206, depending on if your Router is a US or an international version) does not allow to flash 3rd party software any more. You can attempt to see if doing a revert to oder firmware on the help icon will yield version 1.1.4.167984. If the revert goes to anything newer than firmware 1.1.4.167984 you will not be able to gui flash dd-wrt onto the EA8500. Linksys has encrypted the newer files and they will not revert back to an older version.

An extremely helpful page containing links to 1.1.3 and 1.1.4 versions of EA8500 stock firmware and checksums is this: https://www.linksys.com/us/support-article?articleNum=208639 (checked on 06/02/2019)

MRJCD has put together a very good, and detailed, how-to flash from newer, "locked-out", stock builds to dd-wrt using the serial port on the EA8500. Board version 305 XD has had their serial header pins removed too, so you either need to find a Molex KK 5ckt header and solder it on or need to solder on wire leads. What makes it more challenging is that the solder holes will be filled, except the gnd, and there is nearly no copper pad to solder wire or header pins onto the board. There has also been a single report by MSOENGINEER that newer units may have resistors and/or capacitors removed further making it impossible to even use MRJCD's method to install dd-wrt onto the router.

AS SUCH, as of October 2020, WE CANNOT ENDORSE BUYING A EA8500 ANYMORE

[edit] Upload via Web UI

Reset the router first (press the reset button until it reboots). Ignore the warning of “no internet access” being available and go to manual setup. Read the README on http://mrjcd.com/Malachi/KONG-EA8500/. Upload the Kong Build EA8500-factory-to-ddwrt.img for a US router or EA8500WW-factory-to-ddwrt.img for an international one. When the installation is complete (a “Reboot” button appears on the UI), reset the router again. It will boot into dd-wrt, afterwards. You have reached your destination. Note: the BS factory-to-ddwrt build I tried did not boot. After some time, the boot loader switched back to the 1.1.3 stock firmware flashed on preparation. The reaction on the dd-wrt forum was, that BS factory-to-ddwrt builds never seem to have worked.

[edit] Configuration

Do not forget to set the WiFi Regulatory Domain to the country you are operating the router in (check “Advanced Settings”). You may want to follow the recommendations for the WiFi settings here: QCA wireless settings

Builds can be found here: Where can I download firmware? (linksys-ea8500 folder).

[edit] Boot Info

This router's flash has dual system design.

ubootenv get boot_part to know which partition is the currently active boot partition; use ubootenv set boot_part 1 or 2 to active the partition as a boot partition.
