I got a problem.
Bought a second hand z2 today and it sayt it got a update 17.1.2.A.0.314
When I dontload it it sayt cant verify,same with pc companion,but then it says this phone has custom software or something.
I suspect,unlocked bootloader,but when I try to relock bootloader with flash tool it sayt,this phone can not be unloaded officialy?
Someone know how I can fix this?
and is there a way how to check if bootloader is unlocked,like Samsung when u boot with power button and volume up.
