GRLife Pro 2.x now supports the GR IV (Beta)
On a GR III / IIIx? There is no new version this time; nothing to do.
The GR IV Standard and HDF (stock firmware 1.20) can now get GRLife Pro 2.x from the firmware page. As on the GR III / IIIx, press OK while shooting to open the in-camera interface: picking films, setting texture and switching features all happen on the camera. The GR IV version is a Beta; below is what it has and what it doesn’t yet.

What the GR IV gets
- Film library: Five built-in films you can swap on the camera at any time; the other library films and My films work too.
- Film texture: Film grain, HDF diffusion, film softness and light leaks, set per film.
- More aspect ratios: Beside the stock 3:2, 4:3, 16:9 and 1:1: 65:24, 5:4 and 7:6.
- Half frame, guides, ADJ: Half frame shooting and golden ratio guides; ADJ grows to nine settings, with GRLife Pro’s functions in settings 6–9.
- Imprint and shutdown screen: Date imprint and a custom caption, plus shutdown screens you switch in the menu.
Not in the Beta yet
- Films apply to photos only: RAW development and movies use the stock looks for now; that will open once it is stable.
- No HDR photo, slider level or rear dial ISO, and no recipes.
- The GR IV Monochrome is not supported yet. The HDF shares the Standard’s official firmware; camera testing was done on a Standard body.
How to start
- Download the GR IV 1.20 firmware (fwdc248b.bin) from Ricoh’s website.
- Open the firmware page, choose GR IV and your body version, import the official firmware, then generate and download the ZIP.
- Flash the firmware as the chart on the page shows, then copy the ZIP’s GRLIFE folder to the root of the SD card.
- Turn the camera on with the card in and wait about 15 seconds while it copies the app and the film library; then press OK while shooting to open GRLife Pro.
While the camera has no film library of its own yet, start it once with the card in; after that it works without the card too. If anything goes wrong during the Beta, just reply to this email and we’ll fix it as soon as we can.
