Spoiler * Make sure the battery is fully charged.

* Extract the firmware file from archive into a folder called "DCOLYMP" on your SD-Card.

* Put the SD-Card into your camera. Start the camera while holding the OK button pressed. The focus assist LED should turn on - this means the firmware is installing, and you can release the OK button.

* When the installation ends, the focus assist LED will start to blink. Now you can switch the camera off, and then on again. That's all.

Spoiler With the original firmware, you cannot record video more than 28:59. If you try to make a long enough video in high quality, it will be split into several separate MOV files. This was made because of 4Gb file size limitation imposed by FAT filesystem used in the SD cards. In the most of the cameras it's only possible to have 5 such "splits", while E-M1ii, E-M10iii and Pen E-PL9 record up to 13 parts of a video. My modification only removes the first of these limitations, so you can go beyond 29 minutes, and the video duration is only limited by the max number of MOV files.

With the modified firmware, E-M5ii shows the following max recording duration depending on the video quality:

FHD All-I - 0:36:14.

FHD SF - 0:53:49.

FHD F - 1:34:09.

FHD N - 2:38:49. The durations can be different for other camera models. My modification only removes the first of these limitations, so you can go beyond 29 minutes, and the video duration is only limited by the max number of MOV files.With the modified firmware, E-M5ii shows the following max recording duration depending on the video quality:The durations can be different for other camera models.

Hi there,I've made two small hacks in E-M5ii firmware v.4.0.1. An arbitrary autofocus lens can be used for the in-camera focus stacking.2. The video recording time limitations increased from 29 minutes. Now the recording is limited by 5 MOV files the video can be split into (the detailed description is in the bottom of this message).A couple of proof pics for the first hack:The stacking was already tested with Oly 45/1.8, Leica 15/1.7 and Oly MZ 9-18.The same modifications are available for other cameras (the focus stacking will only work in E-M1, E-M1ii and E-M5ii, of course). Here are the links to the firmwares:To install the firmware, you'll need to:It's also possible to revert to the original firmware.The files and the instructions can be found here
