Note: If your device model suffix is S (e.g., E5573s), then only try with E5573s firmware. If your router is E5573Bs, then only try the firmware with Bs suffix. In similar ways, if your device suffix is Cs, then only try with Cs firmware. Wrong firmware may crash your device. If you are getting error 19, try with another firmware or use the boot shot method.
