Device came in my hand in dead condition, mediatek port shows without holding volume buttons. The customer who bring the mobile says origional owner give him in pattern lock condition and he full flash with a pattern unlock file with sp flash tool after that the device is completly dead. I have downloaded OPPO_A31_CPH2015EX_11_A.45_201007 file and extract and flash with unlocktool. After flash it shows like download not completed at the bottom of the mobile. Then I hit oppo|rmx fix dl. Now device condition is its wiping data when powered on even after without holding volume down keys. I'm poor in english, i hope you undrestand. Thank you
