    Looks great, I’ll try it later this day.
    I have Xperia z3 23.1.A.0.726, Tried yesterday other thing (downgrading for rooting and stuff,) nothing worked. So I’ll try this one, And I’ll let you know if it worked.
    I want to block numbers for sms/calls, but the only way to do this, is rooting,.. so i’ll have to do that.

        Don’t understand,… searched the whole f** internet for entering recovery mode,… keeps saying I have to root it, unlock bootloader and then I can get recovery mode,… but to root, I need recovery mode,… but then I first need to root,… don’t understand anymore,… Tried adb, flashtool, even fastboot and androidstudio,… more than 10hours searching and trying, without any effect,.. damn I’m stupid,..

          Hello Vincent,

          Very sorry for not being clear about recovery mode. Can you please try this to enter your phone to recovery mode?

          “Step 1: Turn off your Xperia Z3: press power key and select “power off” or press and hold power key for a few moments.

          Step 2: Power on your device and when the LED notification lights turn on press several times Volume Up or Volume down buttons.

          At the end, your Xperia Z3 will be rebooted into recovery mode.”

            Hi, thanks for your reply, I know how to enter recovery mode, BUT, apperantly my Z3 hasn’t a pre-installed recovery file,… (found it out after having the issue that my phone does not give a LED light by startup)

            so to be able to enter recovery mode , I need to install a custom recovery like CWM or TWRP,… therefore I need to unlock bootloader, and root my phone,..
