TF card not detected on ClonerAlliance UHD Halo - what should I do¶

If the UHD Halo does not recognize your TF card, the side LED will not light up blue. Follow the steps below to troubleshoot and resolve the issue.

Troubleshooting Steps¶

Re-insert the TF card — Remove the TF card and insert it again, making sure it clicks into place securely.
Check the card orientation — Ensure the TF card is inserted in the correct direction. Inserting it backwards will prevent detection.
Clean the metal contacts — Gently clean the gold contacts on the TF card with a soft dry cloth to remove any dust or debris.
Test the TF card on a PC — Insert the TF card into a card reader and connect it to a computer to verify it is readable.
Format the TF card — Format the card to exFAT using a PC. See Storage device formatting guide for ClonerAlliance UHD Halo for formatting instructions.
Try a different TF card — If the issue persists, the TF card may be incompatible or damaged.

The UHD Halo supports large-capacity TF cards with no theoretical upper limit.
For stable 4K recording, use a TF card rated U3 / V30 or above to ensure sufficient write speed.
The TF card should be inserted directly into the UHD Halo’s TF card slot — no adapter is needed.

Note

If the TF card works on a PC but is not detected by the UHD Halo, try reformatting it to exFAT and re-inserting it.
