Coldcard / Bitcoin wallet app Troubleshooting Checks

Coldcard / Bitcoin wallet app troubleshooting is safest when you separate display, sync, device, firmware, and recovery phrase concerns before changing wallet settings. Use official Coldcard support links for device-specific instructions.

Wallet software

Exported wallet file

Xpub import

Derivation path

Passphrase context

Coldcard Troubleshooting Checks

Use these checks to separate ordinary setup friction from wallet safety risk before you reset, restore, reinstall, or open wallet support portals.

PSBT direction

Separate unsigned PSBT export, Coldcard signing, signed PSBT import, and Bitcoin broadcast. Importing the wrong file makes signing look broken.

SD card handling

Card format, file location, filename, adapter reliability, and stale files can all interrupt an air-gapped signing or firmware workflow.

Bitcoin wallet context

Missing balances can come from xpub, script type, derivation path, account index, gap limit, wallet sync, or passphrase context.

Firmware source

Use verified official Coldcard firmware paths. Fake downloads and support pages may ask for seed words to complete a fake update.

Recovery phrase handling

Keep seed words offline and private. Do not photograph them, paste them into support, or use a validation page from an ad or message.

Transaction review

Read the Coldcard screen before signing. Reject unexpected destination, fee, coin selection, change address, or account context.

Likely Causes

Start with the most common causes before resetting the wallet, restoring from a recovery phrase, or trusting a support message.

The Bitcoin wallet app expects an exported wallet file or xpub rather than direct device detection

The wrong account type, script type, derivation path, or passphrase context was imported

The SD card file is missing, unreadable, misplaced, or not the file the wallet app expects

The device is locked, on the wrong menu, or waiting for a different export/signing step

Wallet software, firmware, or computer permissions changed after a previous successful setup

A fake Coldcard helper is steering the user to a cloned download or seed phrase validation page

Recovery And Troubleshooting Steps

Step 1

Confirm the wallet app workflow

Check whether your Bitcoin wallet app supports direct Coldcard connection, air-gapped import, or PSBT-only file exchange for your setup.

Step 2

Match account context

Verify Bitcoin network, script type, account, derivation path, exported xpub, and any passphrase context before assuming funds are missing.

Step 3

Review SD card files

Use a compatible microSD card, confirm the exported file exists, and import the correct file into the wallet app.

Step 4

Avoid unsafe detection fixes

Do not install downloads from ads, type seed words into a detection page, or allow remote access to make a wallet appear.

Coldcard / Bitcoin wallet app And Device-Specific Help

Wallet app

Check the active wallet, import method, watch-only status, account type, Bitcoin network, and whether the app is waiting for a PSBT or signed transaction file.

Coldcard export

Confirm the device created the expected wallet export or PSBT file and that you are not mixing files from a different wallet or passphrase.

USB and SD card

If USB recognition fails, try a direct port and data cable; if air-gapped import fails, focus on card format and file placement.

Coldcard Official Support Checklist

Coldcard Recovery Phrase Safety

No legitimate wallet guidance should need your recovery phrase.

A recovery phrase controls wallet restoration. Treat it as private self-custody information and review how phrases work before using any wallet.
