My BlackVue Dash Cam Is Restarting Randomly. How Do I Fix It?
Preserve your recordings, then work through the card, firmware and power checks for your exact model
Start with the restart pattern
We would start by noting what the camera says and when it restarts. Does it repeat the startup message, report a card error, or lose power when the vehicle moves? Record whether this happens while driving, while parked or immediately after an update. Tell us the full camera model and firmware version, card brand and capacity, and whether it uses a vehicle outlet, hardwire cable or battery pack.
A restart during a firmware upgrade can be part of the documented process. Let that process finish with the required power connected. For repeated unexpected restarts, check the latest saved files before assuming the camera is recording normally. Change one item at a time so you can tell which change made a difference.
Check the card before replacing the camera
BlackVue’s reboot guidance starts with the microSD card, then checks power and firmware. A worn, corrupted or incompatible card can interrupt recording, but a reboot alone does not prove the card is at fault. Continuous recording repeatedly writes and overwrites files, so the card’s condition matters as well as its capacity.
Use the card specification and supported capacities for your exact camera. BlackVue recommends its own cards and warns that other cards can have compatibility issues. A Class 10, U1 or endurance label alone does not establish compatibility with every BlackVue. Confirm the exact card model and capacity before using a third-party card.
After preserving the files you need, compare the result with a known compatible card if one is available. Keep the card type and result in your notes. If the camera still loops with that card, move on to the power and firmware checks rather than repeatedly buying the same card.
A card error is a clue, not a diagnosis
Wear or corruption can interrupt a card’s ability to save recordings. If the camera reports a card error or repeats its startup message, preserve any readable files before trying a format. A recurring restart does not, by itself, identify a damaged sector or prove that the camera needs replacing.
Save the recordings before formatting
- Park safely and power the camera off as its manual directs. Wait for shutdown before removing or reseating the microSD card.
- Use a compatible SD card reader to connect the card to a computer. Identify the card by its name and capacity before selecting a drive.
- Copy the important original recordings and surrounding clips to separate storage. Open those copies to confirm they play. A thumbnail or a still screenshot is not a substitute for the video.
- If the card cannot be read and you need its footage, ask us for help before formatting it. Once the files you need are safely copied, follow the format procedure for the exact camera and software.
Formatting erases recordings. Our BlackVue Viewer guide explains the desktop workflow; choose the local card controls for files on the card. Do not remove or insert a card while the camera is powered on.
Read our BlackVue Viewer guide or check a microSD card reader for your computer.
Use the format method your model supports
Use the camera’s manual to choose between an on-camera control, the BlackVue app and a desktop viewer. The button and menu names differ. A method shown for one model is not a universal sequence for the brand.
For the original DR970X Plus Series, BlackVue documents a Format button: hold it for five seconds, release after the beep, then hold it again for five seconds and release after the next beep. That is a model-specific example, not an instruction to try on a differently labelled button. If the camera cannot stay on long enough, use its documented computer procedure after saving your recordings.
Formatting through the Windows viewer
- Connect the card reader and open the Windows BlackVue Viewer supported by your camera and computer.
- Use the card or folder selection control to confirm the intended microSD drive. Check its name and capacity.
- Open the Format control. In the DR970X Plus instructions, select the card drive and choose Format after the backup is complete.
For the original DR970X Plus, BlackVue specifies FAT32 on Windows and recommends its Viewer when Windows does not offer that format. Use the matching model and software instructions if the controls differ.
Formatting through the Mac viewer
- Connect the card reader and launch the Mac BlackVue Viewer supported by your setup.
- Open its Format control and select the correct microSD card from the drives shown.
- For the DR970X Plus workflow, choose Erase, select MS-DOS (FAT), then confirm Erase only after saving the recordings you need.
These are the model manual’s Mac steps. A different current viewer or camera can have different controls, so keep its instructions beside you. After formatting, safely eject the card, return it to the powered-off camera and confirm normal recording resumes.
Match the firmware to the full model name
If card troubleshooting has not resolved the problem, check the firmware release for the exact camera. Keep DR970X, DR970X Plus, LTE and Box variants separate. Use the official model download and release notes; a similar filename does not make firmware interchangeable.
The DR970X Plus manual describes both an app update and a computer method. Its computer method includes formatting the card and copying the BlackVue folder from the model’s firmware ZIP onto it. Back up first, follow that complete model procedure and keep power connected until the update finishes and normal recording starts.
If the camera cannot maintain the power needed to finish an update, ask us to help establish a stable setup first. Repeatedly interrupting an update is not a useful way to diagnose a restart loop.
Check the connection and the power source
Inspect the visible power lead and connectors with the camera safely shut down. Look for a loose plug, damaged insulation or a cable trapped under trim. Check both the camera end and the power-source end. Secure a loose run with cable clips sized for the lead, leaving the connectors free of strain. A clip cannot repair a damaged cable.
Use a replacement lead only when its connector, wiring and power requirements match the exact camera. A plug that fits does not establish electrical compatibility. A charged battery pack, a working vehicle outlet and a correct hardwire installation are different checks; note which supplies your camera.
For a hardwired setup, have the installer check the required constant, ignition and ground connections and the supply under load. Let them assess the vehicle circuit or battery if power is unstable. Avoid changing cutoff values or substituting a generic USB or household adapter simply to keep the camera running.
If connecting a rear camera or accessory changes the symptom, note that result for support. Power the system down before checking its connections, and use the matching model instructions. The symptom can involve the camera, its cable or the attached device; it does not identify which part to buy.
Cable clips can secure a suitable cable run. Check the fit before use.
Consider when heat or parking power changes the result
BlackVue lists heat as another possible reason for shutdowns or reboots. If the problem follows a long hot parking period, let the unit cool and note whether normal operation returns. Use the temperature and installation guidance for the exact camera. A hot-day pattern is useful evidence, not proof of a specific internal fault.
A camera stopping when its power source switches off is a different symptom from repeatedly restarting while power should be available. Tell us when the vehicle, outlet or battery pack changes state so we can review that setup. Do not disable battery protection just to mask a shutdown.
Keep card maintenance tied to the model and its condition
Follow the format interval in your camera’s manual and preserve useful footage before each format. For example, the DR970X Plus manual recommends monthly formatting. That guidance does not make formatting a cure for every reboot or replace checking that the card records reliably.
Card age alone does not establish the fault. If a known compatible replacement fixes the problem, keep the old card out of recording service and ask the seller about the applicable warranty. Have the purchase date, card model and troubleshooting results ready, and check the terms for that exact purchase.
Send us the results before choosing a replacement
If the camera still restarts after a compatible-card check, the model’s firmware procedure and a verified power supply, contact us for the next step. There may be a hardware issue, but a restart loop is not enough to diagnose the failed component remotely.
Send the exact model and firmware, the card details, the power arrangement, the spoken error and the changes you tried. Include whether the latest files play and whether the problem involves only a rear camera. Keep passwords, private footage and account details out of a public message.

Questions about a BlackVue restart loop
Should I format the card as soon as the camera starts looping?
Save and check the recordings you need first. Formatting erases files. If you cannot access important footage, ask for help before treating the card as disposable troubleshooting media.
Will any Class 10 or U1 card fix the problem?
No. Match the brand guidance, supported capacity and card specification to the exact camera. A speed label alone does not prove compatibility, and a restart can also involve firmware, power or heat.
Does every BlackVue use the same format-button timing?
No. Use the exact model instructions. The DR970X Plus example uses two five-second holds with a release after each beep; do not apply that sequence to another model without checking.
Does a successful format prove the camera is fixed?
Confirm that normal recording resumes and check saved clips. If restarts return, retain the results from each card, firmware and power check so support can investigate the remaining cause.
