R8000 in infinite loop, need help restoring

Hello, 

I installed the latest version of dd-wrt on the netgear R8000. The install was a success. I reached the dd-wrt gui via https. Unfortunately, I changed my wifi settings on the R8000 to Client Bridge mode then saved and rebooted. After that the R8000 went into an infinite loops and keeps rebooting itself. The R8000 is plugged into my home router (fios) and was set as an AP by default. I did not want the AP setting and wanted the R8000 to stand as its own network, say 10.0.0.1 instead of 192.168.1.1 being that my fios router is 192.168.1.10. 

Can someone give me some advice on how to get back into the dd-wrt gui? I was looking forward to setting it up as a VPN Router, using a paid vpn service. I tried holding in the reset button on the R8000 but that did not change anything and the R8000 continues to reboot itself. 

Thanks in advance! 

PS: I installed DD-WRT by Tathagata for NETGEAR R8000 Nighthawk (Rev 29627) 2016-06-04 14:16 from http://www.myopenrouter.com/download/dd-wrt-tathagata-netgear-r8000-nighthawk-rev-29627

I think you need to use a

I think you need to use a toothstick to press/hold the reset button next to the USB 3.0 port to set it to default mode. That's the easiest way.

I bricked my R8000. I bought

I bricked my R8000. I bought a TTL-USB cable and hooked it properly. I am using a MacBook Pro (2011), with Terminal I can:

1) change to the folder where my files are located; ping 192.168.1.1

2)  run TFTP;

3) connect to 192.168.1.1;

4) change mode to binary;

5) but I always get time out when I try to put the chk file to the router

Can somebody help me?

What am I doing wrong?

I got the same issue in my

I got the same issue in my set up. Wireless Client bridge bricks the router. Please do not try to set up wireless client bridge in R8000.

The router can be recovered by flashing Stock firmware using serial console.

I also got the same issue and

I also got the same issue and able to fix it. For fixing this you need a USB-TTL serial cable. Connect successfully it into the router and you will be able to get the router's console. Now follow the steps-

Before starting install TFTP  into your PC(Mine have a LINUX PC).

1. Open the router's console into your PC and Reboot the router.

2. When rebooting press "Ctrl+c" buttons. You will get a command prompt(CFE mode).

3. Type "tftpd" and press enter. Your router will start listening.

4. In your PC open another a new command prompt and go to the directory where the firmwares are located.

      #cd DIRECTORY_NAME

5. Now run the following commands from the other command prompt:

     #tftp 192.168.1.1(assuming that the router have default LAN IP) -m binary -c put FIRMWARE.chk

6. Wait for sometime and check the console until it finish uploading firmware into router.

Enjoy..
