I had exact the same problem. I have flashed several devices with DD wrt but forgot to release the restore button fast enough on the 520. Thanks Smile

It's fixed!

The problem was that I wasn't putting the router into restore mode correctly. Here's the exact steps I used for doing this:-

1. Set the computers IP to 192.168.1.10.
2. Connect the router and computer as usual.
3. Unplug the power cable from router.
4. Press the restore button.
5. Plug in the power cable.
6. Wait for the power LED to go off and then immediate release the restore button (I was holding the restore button for a few more seconds which doesn't work).
7. The power LED will now start to flash and you will be in restore mode.
8. Use the Asus firmware restoration utility to set the firmware.

Thanks to everyone who took the time to help me out,
Rory


Hi Rory and everybody else,

I'm having the same issue like you did but I still can't connect to the router. I can't get past point 6 from above...
If the LAN cable is connected to the laptop the router won't enter into restore mode (I've tried setting the local IP to 192.168.1.9 and 192.168.1.10 but nothing works (both time with subnet mask 255.255.255.0 and preffered dns 192.168.1.1
I'm using Windows10 pro x64, btw....
After the router gets into restore mode (at point 5-6), before connecting the LAN cable I can get a stable slow-pulsing on the power led... The second I connect the LAN cable the power led turns OFF. I've tried connecting the cable both on LAN ports and on WAN.

All this started happening after I tried to connect the Asus router as bridged (or bridged client, I can't recall) with another router.

Doing the 30/30/30 power on/off/on doesn't do anything...

I can't figure it out what am I doing wrong or where can I go from here...

Any help is appreciated and thank you in advance! 🙏🙏🙏

You could try using an unmanaged switch (fast ethernet, not gigabit) between PC and router, adjusting ethernet adapter on PC settings to 100Mbit/s full or half duplex / 10Mbit/s full or half duplex. Per the instructions, you must have the cable connected before powering up the router. Could also be a timing thing. The original link in the OP has been moved (and shall be corrected):

I don't have an unmanaged switch at my disposal...
If I power-on the router with he LAN connected while pressing the restore/"reset" button won't get the router into restore mode (slow flashing)... The router will start "normally": in ~10sec the "air" will turn on and it will stay ON for ~5sec and then "air" goes off.
I'm not sure what you mean about the timing... I've tried releasing the restore/"reset" button right after the power led started flashing (no LAN cable connected as I've said) and after 3 flashes... If it enters the restore mode and I plug the LAN cable the power led will close and won't open even after I remove the LAN cable.

Was the LED flashing fast or slow? Apparently, you may have to do a 30/30/30 then cold boot with reset button pressed for ~5 seconds (or not). There is also the pin 9 short to ground option, and info on how to use serial to clear nvram, etc. Also posting a thread on the GU model about a 30-second reset option, may not be relevant. I will say that Windows 10 sucks sometimes for de-bricking, which is why I suggested changing from auto-negotiate in Windows for the ethernet adapter - and you should have all other adapters, especially wifi, disabled for this. Happy reading.
