Smart Tool keymap import 'failed' on first attempt — Restore DB sequence

MediumTenstore Android ConnectCall of Duty: Mobile3 solutions

When importing a keymap file (.txt) via the Smart Tool, the operation fails with a generic "failed" message. Reimporting the same file produces the same error. This blocks the user from playing because TAC's stock keymap doesn't match Smart Tool's customised layouts.

  • "It did import failed for me / it keeps failing import" — caesarsalad.
  • "Failed diyor" — hawkjrdossantos (TR).
  • Reinstalling the emulator doesn't help.
  • Re-downloading the keymap file from a fresh source doesn't help.

Root cause: TAC's keymap database has a corrupted state from a previous failed launch or a partial Apply that left lock files behind. The next Apply Keymap operation runs but TAC's DB rejects the new entries.

Solution 1

Run "Restore DB" before applying the keymap. Per leonmaxitv1's canonical fix sequence:

  1. Open the Smart Tool.
  2. Click Restore DB (this resets TAC's keymap database to the bundled defaults).
  3. Wait for the success log line: "Settings have been replaced with the bundled defaults."
  4. Click Apply FPS.
  5. Click Apply Keymap again — it should now succeed.

The Restore DB operation clears the corrupted DB row that was rejecting the import. After restore, the apply path runs cleanly.

Make sure the keymap file matches the game mode. TAC's keymap files are per-mode (.txt files for Multiplayer / Battle Royale / DMZ — they don't share the legacy GameLoop's monolithic XML format). Importing a "DMZ" keymap into the Multiplayer slot fails silently with the same "failed" message. Match the file to the mode you're applying it to.

Solution 3

Kill all TAC processes before retrying the import. Smart Tool's Apply Keymap can fail if a CODM process is still running and holds the keymap file open. Open Task Manager → end every "tac", "gameloop", "AndrowsConnect" process → retry import.
