Lost eFootball Mobile Account After Phone Reset

I am a mobile player of eFootball TM, and I recently lost access to my account after flashing my phone. Before resetting the device, I had unfortunately not linked my game account to any external service, so when the phone was flashed, the game data and access to my old account were completely lost. The account I am trying to recover had the in‑game username “KAUNDA254”. I had downloaded and been playing the game through the Google Play Store. I lost access around September 2025, and since then, I have not been able to log back into this account or restore my progress. I have not made any purchases on this account, but I have invested a lot of time and effort into building my team, and I would like to continue playing from where I left off. I kindly request your support to help me recover my old eFootball TM account with the username “KAUNDA254”, or to restore my progress to a new account if possible. I am ready to provide any additional information you may need to verify ownership of the account and complete the recovery process.
