一、用putty 登陆ssh,想办法把固件传到设备上 /tmp 目录,或者用u盘
https://router-sh.ptpt52.com/rom/
二、刷机命令
nvram set flag_last_success=1
nvram set boot_wait=on
nvram set uart_en=1
nvram commit
mtd write lede-ramips-mt7620nand-miwifi-r3-squashfs-kernel1.bin kernel1
mtd write lede-ramips-mt7620nand-miwifi-r3-squashfs-rootfs0.bin rootfs0
reboot
nvram set flag_last_success=1
nvram set boot_wait=on
nvram set uart_en=1
nvram commit
mtd write lede-ramips-mt7620nand-miwifi-r3-squashfs-kernel1.bin kernel1
mtd write lede-ramips-mt7620nand-miwifi-r3-squashfs-rootfs0.bin rootfs0
reboot
