[Q] SIMLOCK - Xperia Z1 C6903 topic

Hi,

I was trying to install the deodexed version of 4.4.2 Stock rom for my C6903
But it stuck at SONY logo,
so i flashed the older 4.2.2 FTF (C6903_14.1.G.1.534_1276-4314_R2A.ftf)
And now my phone is SIMLOCKED what the hell.
It did not have a simlock before, because in Belgium they don't do that.

Is there a way to get rid of it without unlocking bootloader to get full control of device kernel and ****...

FYI - I have a TA Backup of a working 4.2.2 and also of a working 4.4.2, might that help me getting rid of the simlock?

Thanks in advice :)
