Pick your model and import the stock firmware: your browser builds GRLife Pro 2.x firmware and packs it with the files for the SD card. Every feature is inside; switch on what you need in the camera after flashing. Nothing is uploaded or written to the camera.

Custom firmware, test version · The result is unofficial firmware and flashing carries risk; back up first and keep the official firmware.
Ricoh’s November 10 firmware is now supported · You can now build for GR IIIx 1.71, GR III 2.21 and GR IV 1.21. An official firmware update cannot be undone, so decide before you update.
Need the earlier official firmware? · If your camera has not been updated, download the matching version straight from Ricoh’s server: GR IIIx 1.70 · GR III 2.20 · GR IV 1.20
A read-only backup tool is available for GR IIIx Urban Edition 1.60; it opens in a new window.
Nothing to pick here: after flashing, press OK on the shooting screen to open GRLife Pro and switch on what you need on its Features page. Every feature starts switched off.
The GR IV version is in Beta and differs from the GR III / IIIx: no HDR photo, slider level, rear dial ISO or anamorphic lens, and no recipes. Films apply to photos only; RAW development and movies don’t use films yet, and support will open once it is stable. Beside the stock 3:2, 4:3, 16:9 and 1:1 it adds 65:24, 5:4 and 7:6. ADJ functions of GRLife Pro go in settings 6–9.
On the right: where to switch it on in the camera. “About” describes each feature.
The one thing set here: written into the firmware, it replaces the parameters, names and icons of stock image-control positions. Skip it if you do not need it.
Preset nine parameters on the stock image controls; the stock looks stay, and one or two slots is fine.
Each slot can take the recipe’s name and icon as well. The other 8 in-camera slots cannot be customized yet and stay stock. White balance, exposure, ISO and the like from community recipes have to be set by hand in the camera.

GRLife is an unofficial project in which photography enthusiasts study and modify the stock Ricoh GR firmware and its resources. It has no connection with Ricoh Imaging and is neither endorsed nor supported by it. Product names mentioned are trademarks of their respective owners.
Running scripts generated by this site on your camera, replacing in-camera resources or flashing modified firmware all carry risk: the camera may fail to start or be permanently damaged, hardware may fail, photos or settings may be lost, the display may misbehave, and the warranty and manufacturer support will very likely be void.
The tools and the files they produce have had only limited offline verification and testing on a few bodies. Existing tests and user reports do not mean they will work or be safe on your camera. Everything is provided “as is”, without warranty of any kind, including compatibility, stability and recoverability.

The candidate firmware is built only after the local preflight check and the three declarations pass; ticking the risk statement does not lift any other block.
Building the custom firmware on this device…
Your custom firmware is ready
Follow these five steps in order. The first two flash the firmware; the last three let the camera load the GRLife Pro interface and film library.
Press MENU on the camera and run Reset Settings. Settings you changed are cleared, so note them first if you need them.
Unzip the download. Inside is a folder named SD (just a folder in the download, not the SD card) with the files for your card. First copy its BIN file to the root of the SD card (see below). Insert a fully charged battery and this card, hold MENU while turning the camera on, and confirm as prompted. Do not power off or remove the battery or SD card until the update finishes.
After flashing, copy the GRLIFE folder from that same SD folder to the root of the SD card. Copy the folder itself, not just the files inside it. The card should look like this:
On the first start, the camera copies the film library and the new interface from the SD card. This takes about 10 seconds; do not press any buttons meanwhile. You only wait the first time: after that it works as soon as the camera is on, even without the SD card.
Press OK on the shooting screen to open GRLife Pro.Every feature starts switched off.Switch on what you need on the Features page. Under each feature is where to find it in the camera menu: for example, after switching on More aspect ratios, pick a ratio in Image Capture Settings › Aspect Ratio.
To go back, flash the official firmware you kept the same way as in step 2.Full flashing and restore guide
