With volume buttons it will not connect in brom mode, it need to open the phone and soldered test point to ground, oppo f5 f7 and f9 all need to open and solder test point, meta mode reset not working for these phone, most of the above model f5 f7 and f9 mostly hangs on logo after meta reset. Please umt team make unlocking these old phones easy?
