dd-wrt to merlin

[okey]

I have just purchased a RT-AC56U, but I didn't realise it has the dd-wrt firmware on it, but I want merlin on this.

Can I just flash the latest merlin firmware on this via the upgrade or is it more complicated than that.

I have just tried updating the firmware but it just stuck on please wait for about 15 mins, I unlugged it and luckily it rebooted but still on dd-wrt firmware, am I doing something wrong

I just did this recently for a rt-n66 with very old dd-wrt firmware. First did a factory reset and then upgraded it. Worked perfectly!

Bought also a second (main) router. A rt-ac86. Also upgraded to merlin. Works perfectly!

Merlin many thanks!

You have to factory reset to get Merlin working.

ok, do you mean, hold reset button down for 5 secs on back

On the Asus GUI , firmware page there is a factory reset button.

I also did it via the dd-wrt gui AND after a reboot 10 seconds reset button

Maybe try the ASUS firmware restoration utility?

guys, still cant get it to flash, it goes through the procedure of updating, but when it restarts its still on dd-wrt firmware gui.

i have tryed to use restoration utility by holding reset while plugging in and holding 5 sec untill blue led flashes but the utillity will not connect

firmware version on the asus is Firmware: DD-WRT v3.0-r33413 std (09/27/17)

Thanks again guys
