I've searched everywhere, from XDA to Android Enthusiasts and hit a deadend every time. I have a rooted 17.1.2.A.0.314 Kitkat based Xperia Z2. I downgraded the firmware to root it so that I could install a pre-rooted version of the latest Marshmallow ROM via recovery..which doesn't work. I installed XZDualRecovery and later TWRP but when I trigger a reboot to recovery, it doesn't work and the phone restarts normally.
I have tried the button press combos (press volume down during bootup when the light is red, use
fastboot,use the NDRUtils app to trigger reboot to recovery..nothing works.
What do I do?
