美国采购需求：游戏机、掌上游戏机、掌上游戏玩家

We recently experienced an issue with our device after replacing the micro SD card. Unfortunately, all the important data, including the firmware and image files, was lost in the process. Now, the device displays a message asking us to insert an SD card, and we're unable to get it to function properly. Could you please assist us in recovering the required firmware and image files? Any guidance on how to resolve this situation would be greatly appreciated. Thanks for your help!
