Nó yêu cầu phải root thì ko ăn thua rồi, con fireTV của mình lại đang chạy firmware mới nhất.
Prerequisites
•Your Fire TV must be rooted.
•Your Fire TV must be running ClockworkMod Custom Recovery
•Your USB drive must have only 1 partition formated using the EXT4 file system. NTFS, FAT, FAT32, exFAT will not work. Search Google for instructions on how to format a drive with EXT4 as it is not covered in this guide.
•Optional, but recommended – Perform a factory reset before following this guide. Some have run into issues by not first performing a factory reset.
