Hi,
here you can find the firmware:
四代高仿苹果AK2025主控 板号QS_AK2025**屏号FPC888101C | MP3/MP4固件下载区 - 数码之家 - 专业数字产品爱好者社区
You have just to register some times because there is a download limit for new users (fake mailaddress is ok).
But I can磘 update my player because no updatetool works ;-(
Who can help me?
Best wishes
