2 Downgrade stock firmware to 1.317

First install official ReyeeOS 1.317, then upload the Lazy PisoWiFi .bin on the same Local Upgrade page. You only do this once. OpenWrt and PisoWiFi are already inside that .bin.

Part A - Stay on the factory page (LAN only)

  1. Keep the PC on a LAN cable (ports 1 to 3, not WAN).
  2. Open http://192.168.110.1 and log in. Skip or stay off Ruijie cloud.
  3. List down your router serial and mac address. keep it somewhere safe.
  4. On Home, note the current Software Ver. Newer builds (for example 1.380) often reject the LazyFi .bin - that is why the next part installs 1.317 first.

Part B - Local Upgrade to ReyeeOS 1.317

  1. Open System (or Tools), then Local Upgrade. Wording varies by language.
  2. Choose the official file EW_3.0(1)B11P317_EW1200GI_12132412_encrypto.tar.gz (inside the Reyee 1.317 zip from step 1).
  3. Uncheck "Keep Config" then confirm and wait. The page will drop. Give it about 5 minutes. Do not unplug power.
  4. Open http://192.168.110.1 again. On Home, Software Ver must show ReyeeOS 1.317.

Official package: Reyee EW1200G Pro 1.317 firmware.


Part C - Local Upgrade the Lazy PisoWiFi .bin

On the same Local Upgrade page, upload lzdv-pisowifi-ew1200g-sysupgrade.bin (about 9.3 MB). This is OpenWrt 24.10.8 with Lazy PisoWiFi already inside - not a second install later.

Uncheck "Keep Config" then confirm and wait about 5 minutes. The factory page at 192.168.110.1 will stop working. That is expected.

Part D - Confirm Lazy PisoWiFi is running

  1. Set the PC to automatic IP, or manual 10.0.0.2 with subnet 255.0.0.0.
  2. Open http://10.0.0.1/admin/ (default login admin / admin until you change it).
  3. Pisowifi hotspot ssid LazyFi@RuijieEW1200GPRO should appear.
Success

If the dashboard opens at 10.0.0.1, continue to step 3. Plug WAN so the 2-day trial can start (once per router). Guest wifi stays locked until that first online check.
