Xperia Z1 C6903 SIM Locked

I have a Xperia Z1 (C6903) with a SIM Lock from Smart PH, If I flashed the latest firmware 14.2.A.1.136 Global will it cause some damage in the hardware etc... and will that Unlock the sim Lock?

No, you will not Unlock your SIM and you will not damage anything. You will just switch from Branded to Unbranded, so bloatware from your Carrier will gone.

For simlock unlocking go and ask your carrier. They will probably do it for some small fee.

[Q] simple but very important question about locked and unlocked bootloader

I've recently bought a used xperia z but I'm not sure if the bootloader is locked or unlocked.
So my questions are:
1)How do I check this?
2)If the bootloader is locked does this guarantee me that the (stock) rom has not been "modified" previously?
My concerns at security related.

type *#*#7378423#*#* in the phone dialer
then service info>configuration>rooting status
we will have locked bootloader when we bought it
and no bootloader can be unlocked & relocked so don't know,or you can check if the BRAVIA Engine works on Sony Album app or not

According to this link you can but not entirely sure since I've never done it before..
If this if not the case, could you explain to me a little bit more?

It's possible to unlock and relock the bootloader without leaving any trace that it was done. You can check if it's currently unlocked by looking in the service menu. Enter *#*#7378423#*#* in the dialler, then look in Service info - Configuration.
If you're worried just repair the phone with SUS or the PC Companion. This will completely wipe the phone and reinstall the software from scratch, therefore ensuring that nothing is tampered with.
