[Sony Xperia XZ1 Compact Questions & Answers] mstrnemo:
Oke so i finally got araund to do my daily driver sony xz1 compact and when i tried to unlock the bootloader using flashtool also know as sony mobile flasher by androyxde.

I get the following error

ERROR - Cannot invoke “String.split(String)” because the return value of “java.util.Properties.getProperty(String)” is null

Now i looked everywhere on the internet literally and i could not find a awnser to my problem but i did find multiple people with this problem but no defenitive awnser…

but i kept looking and i found that my computer can not find my phone exactlly because when i use command and try adb devices it cant see it but fastboot mode it can.

So i looked for an awnser and said probally need to update your drivers so i downloaded drivers from the sony site installed them then got the message that i have to restart computer before it can go into effect and i do that and then nothing stil does not work i see no adb devices in the list.

oh and i selected the allow unknow drivers from the security option in windos 10 so that should be oke.

I think this might be the problem that adb devices cant be read seeing as it has to be in that mode when trying to unlock the bootloader in flashtool.

This is what it shows in the program
