Recovery Comment:
U-Boot launches a WEB server on 192.168.1.1 if Reset button is held during power up
Comment:
the only difference from Rt-Brd RSIM DS eQ-EP (KNdRt31R19) is lack of SIM injector support

ramips: add support for Kroks Rt-Pot mXw DS RSIM router Aka "Kroks KNdRt31R19". Ported from v19.07.8 of OpenWrt fork: see https://github.com/kroks-free/openwrt for support of other models. Device specs: - CPU: MediaTek MT7628AN - Flash: 16MB SPI NOR - RAM: 64MB - Bootloader: U-Boot - Ethernet: 1x 10/100 Mbps - 2.4 GHz: b/g/n SoC - mPCIe: 1x (usually equipped with an LTE modem by vendor) - Buttons: reset - LEDs: 1x Modem, 1x Injector, 1x Wi-Fi, 1x Status Flashing: - sysupgrade image via stock firmware WEB interface. - U-Boot launches a WEB server if Reset button is held during power up. Server IP: 192.168.1.1 SIM card switching: The device supports up to 4 SIM cards - 2 locally on board and 2 on remote SIM-injector. By default, 1-st local SIM is active. To switch to e.g. 1-st remote SIM: echo 0 > /sys/class/gpio/modem1power/value echo 0 > /sys/class/gpio/modem1sim1/value echo 1 > /sys/class/gpio/modem1rsim1/value echo 1 > /sys/class/gpio/modem1power/value MAC addresses as verified by OEM firmware: vendor OpenWrt source LAN eth0 factory 0x4 (label) 2g wlan0 label
