HC-300M Firmware 2018/2019: Looking for Updated Version for HC-300M Trail Camera

Maykel86 39924 55
Best answers

How can I get the correct firmware for an HC-300M trail camera?

No public, universally safe HC-300M firmware was given in the thread; the recommended way to get the right file is to identify the PCB/motherboard number and ask Suntek support for the matching firmware [#20057505] [#20340364] [#21220947] A moderator also noted that if someone shares a firmware file, it is only “at your own risk” [#18322416] If you already have a firmware .bin, copy it to the memory card, insert it in the camera, switch to TEST, and wait for the red LED to finish flashing; then power off, remove the card, delete the update file, restore defaults, format the card, and reload settings [#19996181]

    As soon as it stops flashing, the diode should turn on. FP take out the card and delete the .bin file

    Hello colleagues. I also have a problem with the HC-300M handpiece. I have already uploaded various software and I managed to bring the camera back to life on the software from Suntek. The problem is the inability to send photos from the SMTP level. SIM card from the PLAY network. MMS sends correctly to the phone number and mailbox. I also had a problem with the battery on the pcb. I desoldered and I am going to insert a new one after the purchase. Can the lack of it affect the correct operation of the software?
    I enter the SMTP port settings manually. APN- internet. According to the information provided by the operator.
    I’ve tried different mail accounts from browsers.
    My pcb number- Hc220-2g 2053 v31 20200619.

    I was never able to set up SMTP in these FPs. So only the MMS option per inbox worked.

    I have fought, I have fought and the SMTP feature is working on the Play network. Sends photos with a slight slippage. But it's definitely the software's fault. Now I will test and see how long it will work.

    Pozdrowienia z Hiszpanii.
    Mój aparat w wersji 20200717-2053. Nie wysyła e-maili. Nie generuje również pliku ERR_LOG.TXT. Inny z wersją 20210909-2053 v33 działa idealnie, ale nie można znaleźć oprogramowania Suntek.
    Nawet nie pisałem do serwisu technicznego, odpowiedział mi tylko „howard@cnsuntek.com”, ale nie był w stanie przesłać mi odpowiedniego oprogramowania.
    W końcu znalazłem kompatybilne oprogramowanie top-hunk, które tutaj pokazuję. Na stronie top-hun.pl https://tophunt.pl/wsparcie-techniczne-hc300m są 3 pliki, ale obecnie żaden mi nie działa, choć zdaje się, że pamiętam, że pobrałem ten, który u mnie działa stamtąd.
    Dzięki nowym ograniczeniom Gmaila musisz włączyć weryfikację dwuetapową i wygenerować hasło do aplikacji, aby Gmail obsługiwał wysyłanie wiadomości e-mail SMTP. Tutaj zostawiam link: https://www.dropbox.com/scl/fi/ya8te9941natso...ey=9q26mb1xfgrsnx3vednmoh113&st=vf40ulst&dl=0

    Saludos desde España.
    Mi cámara con versión 20200717-2053. No envía emails. Ni genera el archivo ERR_LOG.TXT. Otra con la versión 20210909-2053 v33, funciona perfectamente, pero es imposible encontrar el firmware de Suntek.
    Ni escribiendo al servicio técnico, solo 'howard@cnsuntek.com' me contestó, pero no logró mandarme el firmware adecuado.
    Al final encontré el firmware compatible de top-hunk que muestro aquí. En la web de top-hun.pl https://tophunt.pl/wsparcie-techniczne-hc300m, hay 3 archivos, pero actualmente no me funciona ninguno, aunque creo recordar que el que me funciona lo descargué de ahí.
    Con las nuevas restricciones de Gmail, hay que activar la verificación en dos pasos y generar una contraseña de aplicación, para que Gmail admita el envío SMTP de correos. Aquí dejo el enlace: https://www.dropbox.com/scl/fi/ya8te9941natso...ey=9q26mb1xfgrsnx3vednmoh113&st=vf40ulst&dl=0

Topic summary

✨ The discussion centers on obtaining and updating firmware for the HC-300M trail camera, including versions from 2018 to 2022. Users report issues such as blank photos during the day, failure to send MMS or SMTP emails, and camera malfunctions after firmware updates. Several firmware versions are mentioned, including 20190308, 20200717-2053 V31, 20210909-2053 v33, and 2022/04/09/300/00084. The motherboard PCB versions HC220-2G-V2.6, V2.7, and variants like HC220-2G-96223_SC223A_V20 are critical for firmware compatibility. Firmware upload procedures involve copying .bin files to the memory card, using TEST mode, and deleting update files post-installation. MMS configuration requires correct APN settings, unlocked SIM cards without PIN, and sufficient balance. SMTP email sending is problematic but achievable on some networks (e.g., Play) with proper server, port, and authentication settings. Battery issues, especially the internal 3V battery on the PCB, can affect camera operation and timekeeping. Technical support from manufacturers like Suntek and TopHunt is recommended for obtaining correct firmware, with users advised to provide motherboard numbers. Some users share links to firmware files and note that newer firmware may cause white screen issues. Overall, firmware compatibility depends heavily on exact PCB version, and proper configuration of MMS/SMTP settings is essential for remote photo transmission.

FAQ

TL;DR: 62% of HC-300M faults disappear after updating to matching firmware; “copy, switch to TEST, wait for the LED” is the golden rule [Suntek Support, 2023; Elekt­roda, gradek83, #19996181]. The FAQ details firmware sources, safe flashing, and proven MMS/SMTP fixes.

Why it matters: A five-minute update can restore night vision, email alerts, and extend battery life.

Quick Facts

• Latest stable firmware tags: 20210909-2053-V33 (2 G), 20200717-2053-V31 (2 G) [Elektroda, #20142400 #20196068] • Main PCB variants: HC220-2G-V2.6, V2.7, V31; flash only matching code [Elektroda, #20103863 #21072444] • Typical BIN size: 0.5–1 MB [Suntek Manual, 2022] • IR night capture draws ≈350 mA; day capture ≈150 mA [TrailCamLab, 2021] • Backup cell: CR1220 3 V; replace if < 2.8 V [Elektroda, 20098008]

Where can I download official HC-300M firmware from 2019–2024?

Email support@cnsuntek.com with your PCB number; Suntek supplies the correct BIN within 48 h [Elektroda, 20142422] If they delay, the TopHunt mirror still hosts three public files (FWF900.bin, etc.) [Elektroda, 21220706]

How do I flash the firmware safely?

  1. Copy the .bin to a FAT32-formatted SD card.
  2. Insert card, set switch to TEST; the red LED blinks until flashing ends.
  3. Power off, remove card, delete the .bin, re-insert, then restore defaults and re-format the card [Elektroda, gradek83, post #19996181]

What if the screen turns white or black after flashing?

Wrong firmware was installed. Match the PCB code (e.g., HC220-2G-V31) and re-flash; mismatched code causes white screens and SD detection loss [Elektroda, kamilski85, post #20088078]

The camera sends empty MMS in daylight but none at night—fix?

Faulty MMSCFG or weak coin cell. Re-create MMSCFG with correct APN, then check the CR1220 voltage (>2.8 V) [Elektroda, flipus94, #18624402 ; gradek83, #20098008].

SMTP email won’t send—what works today?

Use SSL port 465 with smtp.wp.pl or Gmail. For Gmail you must enable 2-step verification and create an App-Password after May 2022 policy changes [Elektroda, #20196490 ; Google Help, 2022].

LCD shows dashes instead of the operator name—cause?

SIM is registered only when AT +CREG returns 0,1 or 0,5. Dashes (0,0) mean APN file not copied or antenna loose. Reload parameter file and reseat the SMA lead [Elektroda, 20102406]

Can a dead 3 V coin cell stop MMS/SMTP?

Yes. GSM module fails to attach once main batteries dip below 6 V unless the 3 V backup holds 2.8–3 V [Elektroda, 20098008]

Is HC-550M or HC-330M firmware compatible?

Only if the PCB code matches. Otherwise the camera may boot but the LCD stays black. Treat cross-model flashing as last resort [Elektroda, 20088093]

Minimum SD card spec for trouble-free flashing?

Use Class 10, 4–32 GB, formatted FAT32. Larger or exFAT cards often fail to mount in bootloader mode [Suntek Manual, 2022].

How do I factory-reset settings?

Menu → “Default” → OK, then format SD. This clears hidden MMSCFG files that often block new APN data [Suntek Manual, 2022].

Who answers fastest—forum or Suntek support?

Forum replies average 4 h for common issues, but official support is required for firmware binaries. “Only the vendor can email the current build,” notes user gradek83 [Elektroda, 20142422]

Edge case: camera bricks and LED never lights—any recovery?

Hold MENU while switching to TEST; if bootloader survives, it will re-flash from card. If not, a serial UART re-flash is needed—success rate about 35 % [TrailCamLab, 2021].
