Hello all.
I need some help how to update the z2 to lollipop.
I've read stuff on internet, but I simply can not do it.
The error 2003 is killing me... And I do not know what to do.
A month ago I bought a z2 for my brother and it was/is on kitkat.
Today, I bought a z2 for my father and there was lollipop already installed.
I bought both phones via Ebay.
The phones have the same Model Number.
On the kitkat z2 I cant update via OTA either.
Could you PLEASE tell me what to do?
I have read something, that my bootloader may be unlocked and I have to relock it.
Is that true? And if yes, how can I check if my bootloader is locked?
Thanks in advance!
