Flashing openwrt gone wrong on xiaomi r3?

So i just tried flashing openwrt for the first time, on my xiaomi r3, i did everything by the flash instructions

Flash instructions:

  1. unlock ssh access via https://openwrt.org/toh/xiaomi/mir3#get_sshdropbear_access
  2. insert a usb stick (FAT/FAT32) with copied two firmware files (.bin)
  3. in ssh:
    nvram set flag_last_success=1
    nvram set boot_wait=on
    nvram set uart_en=1
    nvram commit
    cd /extdisks/sda1
    mtd write openwrt-ramips-mt7620-xiaomi_miwifi-r3-squashfs-kernel1.bin kernel1
    mtd write openwrt-ramips-mt7620-xiaomi_miwifi-r3-squashfs-rootfs0.bin rootfs0

and after reboot the router never turn blue led, lan ports seems to work, when i check on my pc, the router seems to be connected, but it doesnt assign ip to my pc, is there any way to recover from it or its just gone?
