From d8f4453bf2de9fd9baf3d660ed12e0797ff2cfdb Mon Sep 17 00:00:00 2001 From: David Bentham Date: Fri, 10 Nov 2023 18:50:38 +0000 Subject: [PATCH] mediatek: add Comfast CF-E393AX support Comfast CF-E393AX is a dual-band Wi-Fi 6 POE ceiling mount access point. Oem firmware is a custom openwrt 21.02 snapshot version. We can gain access via ssh once we remove the root password. Hardware specification: SoC: MediaTek MT7981A 2x A53 Flash: 128 MB SPI-NAND RAM: 256MB DDR3 Ethernet: 1x 10/100/1000 Mbps built-in PHY (WAN) 1x 10/100/1000/2500 Mbps MaxLinear GPY211C (LAN) Switch: MediaTek MT7531AE WiFi: MediaTek MT7976D LEDS: 1x (Red, Blue and Green) Button: Reset UART: 3.3v, 115200n8 -------------------------- | Layout | | ----------------- | | 4 | VCC GND TX RX | <= | | ----------------- | -------------------------- Gain SSH access: 1. Login into web interface (http://apipaddress/computer/login.html), and download the configuration(http://apipaddress/computer/config.html). 2. Rename downloaded backup config - 'backup.file to backup.tar.gz', Enter 'fakeroot' command then decompress the configuration: tar -zxf backup.tar.gz 3. Edit 'etc/shadow', update (remove) root password: With password = 'root:$1$xf7D0Hfg$5gkjmvgQe4qJbe1fi/VLy1:19362:0:99999:7:::' 'root:$1$xf7D0Hfg$5gkjmvgQe4qJbe1fi/VLy1:19362:0:99999:7:::' to Without password = 'root::0:99999:7:::' 'root::0:99999:7:::' 4. Repack 'etc' directory back to a new backup file: tar -zcf backup-ssh.tar.gz etc/ 5. Rename new config tar.gz file to 'backup-ssh.file' Exit fakeroot - 'exit' 6. Upload new configuration via web interface, now you can SSH with the following: 'ssh -vv -o HostKeyAlgorithms=+ssh-rsa \ -o PubkeyAcceptedAlgorithms=+ssh-rsa root@192.168.10.1'. Backup the mtd partitions - https://openwrt.org/docs/guide-user/installation/generic.backup 7. Copy openwrt factory firmware to the tmp folder to install via ssh: 'scp -o HostKeyAlgorithms=+ssh-rsa \ -o PubkeyAcceptedAlgorithms=+ssh-rsa \ *-mediatek-filogic-comfast_cf-e393ax-squashfs-factory.bin \ root@192.168.10.1:/tmp/' 'sysupgrade -n -F \ /tmp/*--mediatek-filogic-comfast_cf-e393ax-squashfs-factory.bin' 8. Once led has stopped flashing - Connect via ssh with the default openwrt ip address - 'ssh root@192.168.1.1' 9. SSH copy the openwrt sysupgrade firmware and upgrade as per the default instructions.
