mình flash 1 phát, báo lỗi k cho flash. bây giờ thì như vậy luôn

kẹp nguồn bấm xem kim có nhúc nhích gì ko .nếu kim nhic lên đo thử mấy áp cơ bản mà có thì khả năng em flash yếu quá rồi

dao động vẫn còn tốt, cắm usb mở nguồn vẫn còn lên nokia, mình nghĩ con flash sắp tiêu rồi
tiền sử máy hay bị mất nguồn

Đem qua box khác flash lại xem sao anh.

resoldering em nó phát rồi sw lại

đã làm chân đóng lại vãn vậy, mình trả máy luôn rồi
thank AE!
