Xiaomi Mi R3G from Padavan, how?

@targa I don't know if you still need this. Anyway, I would post a simple solution here as someone may need it.
Since you have flashed your device with Padavan, I guess you should have flash the breed bootloader.

It's really simple to flash openwrt onto your devices with breed.

  1. Restart to breed. (Unplug the power line then plug with reset pressed)
  2. Download kernel1 and rootfs0 from OpenWrt Firmware Selector.
  3. Select upgrade firmware.(更新固件 for Chinese user)
  4. Select "OpenWRT" mode.
  5. Upload the kernel1 and rootfs0 files.
  6. Done
