Dear Mr.Minh,
Could you sharing share me file KERNEL and ROOTFS?

bác có nhận flash dòng này ko vậy, tks!

Chào bạn, mình đã kết nối như hướng dẫn của bạn, nhưng chưa biết tiếp theo làm thế nào. Mình ko phải Dev nên chưa hiểu các Code như này là thế nào. Mình đang dùng Nokia WI2B-AC220i bị brick như hình. Bạn hướng dẫn sơ qua cho mình bước tiếp theo làm thế nào được ko ?
