Trước em dùng vẫn bình thường, lúc em tháo pin ra để lắp sim khác quên không tắt nguồn, tháo thẳng ra luôn. Lúc lắp lại không lên, chỉ rung máy.
Em nghĩ là lỗi hệ điều hành, dùng phoenix để flash lại máy, ngày trước chỉ mất vài phút là xong, nhưng bây giờ thì không làm sao cài lại được.
Bác nào cao tay giúp em, em xin cám ơn và hậu tạ
Em ở Thanh Xuân - HN, bác nào ở gần đấy giúp được thì pm lại cho em nhé
