Again I got the files and made FTF for you guys.
17.1.A.2.69 only available to Operator Version now
AS I KNOWN, THERE ARE 5 COUNTRIES’ Orange Z2 has 69FW.
BUT AS THEY ARE NOT ON SALE, I POST FR ONLY.
This FW can be flashed to any D6503 with all function work(include 4G)
BTW, there are full of bloatware. (┬＿┬)
thx my friend @rimas
