Fujifilm has withdrawn the recently-released Version 4.0 of the firmware for its X-T2 camera due to ‘malfunctions in the firmware’.

The company has published the following details of the problem and a temporary solution for people who have upgraded their cameras on its website:
1.When RAW files, which were taken by X-T2 (before firmware ver.4.00), are converted in camera (ver.4.00) or by “FUJIFILM X RAW STUDIO”, they are not converted properly.

2.When pressing the shutter button halfway under certain conditions, the live view can flicker.

3.In rare cases, a hang-up can occur.

We will inform you later of the detail of fixed firmware for the malfunctions.
As a temporary solution for customers who have upgraded the firmware to ver.4.00, we have prepared a new firmware version of 4.01 whose functions are same as the ver.3.00.
Please update your camera to ver.4.01 to avoid the malfunctions.
*Ver.4.01 doesn’t include the additional functions of ver.4.00.
