Correcting Known Issues with VIOFO Dash Cams
Help for an A119 or A119S that freezes, stops responding or misses recordings
Start with the symptom and camera model
This guide covers the older VIOFO A119 and A119S families. The names matter: an A119 V3 or A119 Mini needs its own model instructions. Tell us which camera you have and whether it:
- Stays on the startup logo.
- Shows X marks across the LCD.
- Stops responding to its buttons.
- Fails to record reliably.
We want you to leave with footage you can use, so a camera that starts again still needs a recording check. Avoid treating a successful update as proof that the original fault has gone.
Protect your recordings before changing the card
Formatting erases the card. Copy the recordings you need to another device before you format it. If important footage is inaccessible, stop before formatting and ask our team about your next step.
Write down the camera model, current firmware version if you can read it, and your usual recording settings. Read the matching VIOFO update article before starting so you have its files and power instructions ready.
Choose the correct A119 or A119S instructions
Use the VIOFO firmware support folder to find your exact model. These two manufacturer articles describe different update files:
On a small screen, swipe the table to read both columns.
| Camera family | Manufacturer instructions |
|---|---|
| A119 / A119 V2 | A119 and A119 V2 firmware. The article distinguishes firmware V1.1 or earlier, which needs a loader step, from newer firmware that skips that step. |
| A119S / A119S V2 | A119S and A119S V2 firmware. This article specifies its own file and powering the camera through its side port. |
Keep the manufacturer's filenames. A file for a similarly named camera is not a substitute. If you cannot identify the model or the required loader sequence, let us help before you copy anything.
Work through the update without interrupting power
- After backing up footage, format a compatible microSD card as the exact article directs. Both linked legacy-model articles specify FAT32; the A119 article permits formatting by camera or computer.
- Download the files from that model's official article. If the download is compressed, extract the required file before copying it.
- Copy the required file to the card and follow any separate loader sequence. Keep the original filename and extension.
- With power disconnected, insert the prepared card. Connect power as the model instructions specify. On the A119S, the REC light flashes rapidly during the upgrade.
- Do not disconnect power while the update runs. Wait for the camera to restart after completion.
If the sequence does not behave as described, stop and check the model, file and card preparation with us. Repeatedly trying files from other cameras is not a recovery plan.
Check a saved recording before relying on the camera
After the restart, check the firmware version and review your settings, including date, time and audio preference. Record a short clip, then open the saved file and check that it plays. Try the buttons that were failing and look at the LCD again.
If the same fault returns, tell us whether the update changed any of the symptoms. Keep important recordings backed up while we help you work out the next step.
Common questions
How can I prepare the card if the camera is stuck on the logo?
The A119 firmware article allows formatting the card on a computer. Save any footage you need first, and use the file system and model-specific sequence in the article. If your computer cannot read important footage, pause before erasing the card.
Can I use A119 firmware on an A119S?
No. VIOFO publishes separate files and instructions for these families. Match the name on your camera to the official article, including any version-specific loader step.
Does the camera restarting mean everything is fixed?
A restart is only part of the check. Open a newly saved recording and test the controls involved in the fault. Contact us if the screen, buttons or recording problem continues.
