Steps outlined here are required to recover bricked AC120 E6120 Wifi-extender by Netgear. The firmware upgrade procedure didn't go too well on mine. It ended up blinking the power LED over and over, without any network activity.
git clone git@github.com:wkoszek/netgear_recovery.git
cd netgear_recovery
unzip EX6120-V1.0.0.46_1.0.29.zip
- Follow steps above
- Disconnect from Wifi
- On a PC/Laptop, connect an Ethernet cable between the device and your laptop.
- On Macbook, get a dongle to get a Ethernet connectivity and connect the cable to the device
- Open Terminal
- Set your IP address as
192.168.1.10 - Start
tftp 192.168.1.1 69 - Set mode to binary:
mode binary - Upload the file:
put EX6120-V1.0.0.46_1.0.29.chk
The most critical step is the configuration of the binary mode. Without it, the device won't start receiving the firmware.
