Hasselblad published firmware 1.3.16.1 for the X2D II 100C today, the same day Phocus Mobile for Android V1.0.0 landed. No press release for the firmware, no email, nothing on their news page. My firmware tracker caught it this morning.
The release notes list exactly two changes, and one of them explains the timing. Download link and the full notes are below.
Key finding: Hasselblad released X2D II 100C firmware 1.3.16.1 on 2026-07-16, the same day Phocus Mobile for Android V1.0.0 launched. The notes list an Android mass-storage connection optimisation and a fix for inaccurate exposure preview of interval drive mode photos. Downgrade is not supported after installation.
Where do you download X2D II firmware 1.3.16.1?
The firmware is a direct download from Hasselblad's CDN: X2DII_100C_v1_3_16_1.cim (366 MB). You can click that link and save the file directly, or grab it from the Hasselblad Firmware Tracker, which lists current firmware and release notes for every X System body, lens, and 907X back in one place.
It should also surface through Phocus Mobile's in-app update prompt the next time you connect the camera.
What does firmware 1.3.16.1 change?
Verbatim from the release notes¹:
What's New - Optimised the connection experience for Android devices in mass storage mode. - Fixed issue where photos taken in interval drive mode displayed inaccurate exposure during preview in certain scenarios.
Notes - Downgrade is not supported after the update. - "Update is completed!" will be shown on the touch display once the update is successful.
Two items. By Hasselblad release-note standards that is almost verbose; the previous release, 1.2.7.16, said only "improved stability and overall user experience."
The interval drive mode item is the one change with nothing to do with Android. Read it carefully: it fixes the exposure shown when previewing photos taken in interval drive mode, not the exposure captured in the files. If your interval sequences looked wrong on the rear display but fine in Phocus, this is why.
Have you seen the guide? I've published Essential Phocus 4.x for Mac - 85 topics across 8 sections and 246 pages covering everything from HNCS color science to HDR workflows. It's the reference manual Hasselblad hasn't updated since 3.8. It's $49, and updates are included.
The Android connection item explains the timing
Phocus Mobile for Android V1.0.0 launched today, 2026-07-16, supporting the X2D II 100C, X2D 100C, and 907X & CFV 100C². After years of Phocus Mobile 2 being iOS and iPadOS only, Android owners finally get a native workflow³.
Phocus Mobile talks to the camera over USB with the X2D II in mass storage mode, and this firmware's headline item is "optimised the connection experience for Android devices in mass storage mode." I have not seen Hasselblad state a dependency between the two releases, but a camera-side Android connection fix shipping the same day as the company's first Android app is not much of a mystery. If you plan to use the new Android app, treat this firmware as part of the package.
For Mac and iPhone users, that leaves the interval preview fix as the only change that touches you.
What the file itself reveals
The .cim container is 365,668,864 bytes, a full camera OS image like every X2D II firmware before it, which is also why downgrade is not supported (the old image is not preserved).
Inside the header: a build date of 2026-06-23 and an internal version string of 10.00.09.76, distinct from the user-facing 1.3.16.1. The file reached Hasselblad's CDN on 2026-07-15 and went live today. That three-week gap between build and release matches the pattern I noted with 1.2.7.16, and lines up neatly with a build held back to ship alongside the Android app.
How to install
The flow is unchanged: copy the .cim to a freshly formatted CFexpress card, insert it, and run Menu, General Settings, Firmware, Update. Charge the battery first, do not interrupt the update, and remember there is no way back to 1.2.7.16 afterwards.
Phocus Mobile's in-app update remains the gentler option if firmware-by-card makes you nervous. It downloads, verifies, and pushes the file over the connection.
I keep a running history of every X2D II firmware release, with dates and what each one actually changed, in X2D II Firmware Updates Since Launch. If you want an email the day the next one drops, the firmware tracker page has a one-click alert signup; today's alert went out about four hours after the file appeared.
