The Gemtek WVRTM-127ACN is an indoor dual band wifi router
with internal antennas and 3 Gigabit Ethernet ports.

The Gemtek WVRTM-130ACN is an indoor dual band wifi router
with external antennas and 5 Gigabit Ethernet ports.

Hardware of WVRTM-127ACN:
- SoC: Mediatek MT7621AT (880 MHz, dual core)
- RAM: 128 MB
- Storage: 128 MB NAND SLC flash

- USB: 1x 3.0
- Power: 56 VDC, 0.54 A, PoE+ IN (WAN)
- PoE: 1x PoE+ 802.3af/at (WAN)
- Uart: GND RX TX VCC - J2 (GND near WAN)
- Board silkscreen: "WVRTM-127ACN_V02" "19K-513-8500R" "RoHS" "1717"

Hardware of WVRTM-130ACN:
- SoC: Mediatek MT7621AT (880 MHz, dual core)
- RAM: 128 MB (Kioxia TC58BVG0S3HTA00)
- Storage: 128 MB NAND SLC (Winbond W971GG6SB-25)
- Ethernet: 5x 10/100/1000 Mbps LAN1,LAN2,LAN3,LAN4 & WAN

- Power: 56 VDC, 0.54 A, PoE+ (WAN)
- PoE: 1x PoE+ 802.3af/at (WAN)
- Uart: GND RX TX VCC - J2 (GND near WAN)
- Board silkscreen: "WVRTM-130ACN_V01" "19K-515-4500R" "RoHS" "2112"

Enable access to uboot menu (needed in wvrtm-130acn):
- The access to uboot menu is blocked by `bootdelay = 0` set in ubootenv.
With stock firmware version 01.01.02.163 and previous, you can use CVE 2020-24365
command injection https://nvd.nist.gov/vuln/detail/CVE-2020-24365
    python3 exploit.py -t 192.168.1.1 -c "fw_setenv bootdelay 3; fw_saveenv"

Backup the stock firmware:
- Connect via uart
- Connect via ethernet and assign your pc the address 192.168.15.x/24
- Power on the device; and start typing '4' to enter uboot menu
- Set factory mode and boot
    MT7621 # setenv factory 2; saveenv
    MT7621 # nand read 2800000 2000000 81000000; bootm
- Telnet and copy all mtd blocks
    telnet 192.168.15.1
- Copy all mtd blocks and start webserver
    for N in $(seq 0 6); do dd if=/dev/mtd$N of=/tmp/eeprom_mtd$N.bin; done
    mount -o bind /tmp /www
    lighttpd -f /etc/lighttpd.conf
- Backup stock rootfs_data (optional)
    dd if=/dev/mtd7 of=/tmp/eeprom_mtd7.bin
    dd if=/dev/mtd8 of=/tmp/eeprom_mtd8.bin
- Download to your pc from http://192.168.15.1/eeprom_mtd$N.bin

Installation:
- Connect via uart
- Connect via ethernet and assign your pc the address 10.10.10.3/24
- Start a tftp server and serve the image initramfs-kernel.bin
    mkdir /tmp/ftpd;
    cp initramfs-kernel.bin /tmp/ftpd/kernel.bin
    dnsmasq --enable-tftp --tftp-root=/tmp/ftpd
- Power on the device; and start typing '4' to halt the bootloader
- Change the active mtd partition from mtd6 to mtd5 (needed by uboot)
    MT7621 # setenv mtddevnum 5; saveenv
- Write the openwrt initramfs in ram via tftp and boot it
    MT7621 # tftpboot 81000000 kernel.bin; bootm
- From the initramfs create the ubi device and install openwrt via sysupgrade
    ubiformat /dev/mtd11 -y
    sysupgrade -n -v /tmp/sysupgrade.bin

Recovery:
Restore the stock firmware from the backup of the mtd blocks
    mtd write eeprom_mtd5.bin firmware
    mtd write eeprom_mtd6.bin Kernel2
    mtd write eeprom_mtd7.bin Storage1
    mtd write eeprom_mtd8.bin Storage2
    ubiformat /dev/mtd8 -y
    reboot
