From 1b091311aafc59db576a51b3d2b5febaac45d522 Mon Sep 17 00:00:00 2001 From: Mikhail Zhilkin Date: Sun, 12 Nov 2023 07:58:26 +0000 Subject: [PATCH] ramips: add support for Sercomm CPJ routers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This commit adds support for following wireless routers: - Rostelecom RT-FL-1 (Serсomm RT-FL-1) - Rostelecom S1010 (Serсomm S1010.RT) The devices are almost identical and the only difference is one bit in the factory image PID (thanks to Maximilian Weinmann (@MaxS0niX) for the info and idea to make one PR for two devices at once). Devices specification --------------------- SoC: MediaTek MT7620A, MIPS RAM: 64 MB Flash: 16 MB SPI NOR Wireless 2.4: MT7620 (b/g/n, 2x2) Wireless 5: MT7612EN (a/n/ac, 2x2) Ethernet: 5xFE (WAN, LAN1-4) BootLoader: U-Boot Buttons: 2 (wps, reset) LEDs: 1 amber and 1 green status GPIO leds 5 green ethernet GPIO leds 1 green GPIO 2.4 GHz WLAN led 1 green PHY 5 GHz WLAN led 1 green unmanaged power led USB ports: No Power: 12 VDC, 1 A Connector: Barrel OEM easy installation --------------------- 1. Remove all dots from the factory image filename (except the dot before file extension) 2. Upload and update the firmware via the original web interface 3. Wait until green status led stops blinking (can take several minutes) 4. Login to OpenWrt initramsfs. It's recommended to make a backup of the mtd partitions at this point. 4. Perform sysupgrade using the following command (or use Luci): sysupgrade -n sysupgrade.bin 5. Wait until green status les stops blinking (can take several minutes) 6. Mission acomplished Return to Stock --------------- Option 1. Restore firmware Slot1 from a backup (firmware2.bin): cd /tmp mtd -e Firmware2 write firmware2.bin Firmware2 printf 1 | dd bs=1 seek=$((0x18007)) count=1 of=/dev/mtdblock2 reboot Option 2. Decrypt, ungzip and split stock firmware image into the parts, take Slot1 parts (kernel2.bin, rootfs2.bin) and write them: cd /tmp mtd -e Kernel2 write kernel2.bin Kernel2 mtd -e RootFS2 write rootfs2.bin RootFS2 printf 1 | dd bs=1 seek=$((0x18007)) count=1 of=/dev/mtdblock2 reboot More about stock firmware decryption: Link: https://github.com/Psychotropos/sercomm_fwutils/ Debricking ---------- Use sercomm-recovery tool. You can use "ALL" mtd partition backup as a recovery image.
