Xperia Z1 C6903 SIM Locked - Xperia Z1 Q&A, Help & Troubleshooting

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.

I think the lt30a is the AT&T phone. You may be able to get an unlock code from them. I had no problem getting an unlock code from AT&T when I sold my S3 to buy this phone.
EDIT: I read this wrong. the AT&T version is lt30at. Sorry.
yes.
from what i undestand it was bought in uk.
some people are confusing the 2 unlock types
Just in case, the sim unlock process is a simple one, just insert another sim from the other provider and enter the code provided.
Unlocking the bootloader is not possible with some versions including the lt30a - at least a method does not yet exist - unless you are working with the models that have unlocking enabled. Check other posts which cover this topic extensively.
yes i know it asks for the SIM network unlock PIN, i do not have one.
and also i know that the bootloader isn't unlockable, i've checked in service info. i don't need unlocked bootloader for now as i have rooted the latest stock 4.1.2, only problem i have it with the sim lock..
got the sim network unlock pin from network operator, thread can be closed

[Q] Impossible to debrand (Unlock) my Z1?

Hello!
I have a Sony Xperia Z1 C9603
Currently running
757 by [NUT] ( I followed this guide he have in Z1 General section )
I'm currently locked to the carrier "3 (Three)" and i wish to have it SIM-Unlocked so i can use my other SIM-Card i have,
Is this possible?
Because no matter what FTF i choose the phone is still branded and when i start the phone it keep asking me for "PIN-Code To Unlock Network"
So right now i don't have any connection at all on the phone.
Could someone please help me?
Sim lock has nothing to do with which firmware you are running.
You must either speak to your network provider or pay someone in a mobile phone shop to get it sim free
Unlocking the bootloader should allow sim unlock

The only way is to pay for a code, either from your carrier or 3rd party site. Any O2 contract owners can do it for free though.

Might be on the Z1, but I've unlocked boot loaders on a lot of HTC's and that has resulted In a sim unlock

Not on Sonys, which I've owned a few of. You need a code.
