Rollei Actioncam 372 Firmware Update Guide

User question

rollei actioncam 372 firmware

Artificial Intelligence Response

Direct answer to the question

• The official, user-installable firmware for the Rollei Actioncam 372 (SKU 40140 / 40145) can be downloaded from the Rollei “Download Center” (2.31 MB package, last updated 28 Dec 2023).
• URL: https://downloads.rollei.com/en/download/actioncam-372-2/
• Update by copying the extracted firmware file(s) to a freshly-formatted (FAT32) micro-SD card, inserting it into the switched-off camera, and powering-up; the upgrade starts automatically.
• Use only the file that matches your SKU; flashing the wrong build can brick the camera.

Detailed problem analysis

1. Why firmware may be required
    – Bug fixes (boot freezes, Wi-Fi dropouts, inaccurate date/time).
    – Language pack additions (Czech, Polish, etc.).
    – Improved codec bit-rate stability for 1080 p 30 fps mode (Rollei changelog 2023-12-28).

2. Hardware/firmware relationship
    – Actioncam 372 is an OEM variant built around an Allwinner V3-S SoC and an AIT8427 ISP.
    – Boot ROM looks for “firmware.bin” (or “FWUPDATE.BRN” in earlier lots) in root of the uSD, verifies CRC, then re-flashes the SPI NOR.
    – If power is lost during the 35–40 s write cycle the bootloader is erased ⇒ camera will not start without serial-USB and a factory image; therefore full battery or external 5 V ≥1 A supply is mandatory.

3. Version verification
    Menu > Setup > System Info displays a string such as “V1.0.7_20231228”. Anything below V1.0.7 is considered outdated.

Current information and trends

• Rollei has revived support for several legacy budget action cams since Q3 2023; 372 received its first public user-flashable package on 29 Sep 2020, latest refresh on 28 Dec 2023.
• Trend: Many low-cost cameras are now delivered with encrypted OTA capability; 372 still relies on manual SD-card update, so end-of-life servicing remains in the user’s hands.

Supporting explanations and details

Update workflow (recommended):

1. Identify SKU on the name-plate or packaging.
2. Download ZIP from link above → extract → resulting file is usually “FW372_40140_40145_v1.0.7.bin”.
3. Format ≥4 GB Class-10 uSD to FAT32 with 32 kB clusters.
4. Copy *.bin to root (no folders, keep name).
5. Insert card, keep battery ≥80 %, connect USB power if possible.
6. Power-on → blue/red LEDs flash alternately → screen shows “UPD” counter.
7. Camera auto-reboots, deletes update file, then loads normal menu.
8. Re-enter System Info; confirm new version.
9. Format the card once again to remove residual update blocks.

Troubleshooting quick table
• Update doesn’t start → wrong filename, card not FAT32, card >32 GB exFAT, or SKU mismatch.
• Stuck on logo after update → redo process with freshly downloaded file; use different uSD (avoids bit-flip errors).
• No power after failed flash → contact Rollei service; only JTAG / UART + FEL mode re-flash can recover.

Ethical and legal aspects

• Only proprietary Rollei binary is licensed for redistribution; do not share modified builds.
• Installing third-party firmware (e.g., generic Allwinner V3 hacks) may violate warranty and local consumer-protection law, and can infringe codec patent licences.

Practical guidelines

Best practices before every firmware attempt:
– Back-up important clips.
– Perform a “Restore Defaults” to minimise configuration conflicts.
– Use branded uSD (SanDisk Extreme, Samsung Pro, Kingston Canvas Go).
– Verify MD5/SHA-256 hash of the downloaded ZIP (Rollei publishes checksums in the file description).

Potential challenges and mitigation:
– Counterfeit uSD cards → test with H2testw (Windows) or F3 (Linux/macOS).
– Battery sag below 3.4 V during flash → keep USB supply connected.
– Different hardware revision (rev-C PCB) sold by some retailers in 2019 → choose 40145 build instead of 40140.

Possible disclaimers or additional notes

• Downgrading is not officially supported; if you must, use the same procedure with an older BIN, but risk remains yours.
• Rollei may remove files when product reaches EoL; mirror the package locally.

Suggestions for further research

• Analyse the Allwinner V3-S SDK to enable higher bit-rate profiles (>24 Mb/s) while preserving Rollei’s UI.
• Explore open-source wrappers (e.g., OpenIPC) but only on test units; community support is nascent for this chipset.
• Monitor Rollei’s RSS feed for future language-pack updates.

Brief summary

The Rollei Actioncam 372 now has an official public firmware (2.31 MB, v1.0.7, 28 Dec 2023). Download it from Rollei’s site, copy the BIN to a FAT32 micro-SD, insert, power-on, wait for automatic flashing, then verify the new version in System Info. Use only the firmware that matches your SKU to avoid bricking the camera; keep a fully-charged battery and a reliable SD card to ensure a safe update.
