network locked - Xperia Z1 Q&A, Help & Troubleshooting

Hi, i changed my c6903 from 5.1 to 4.4.4 and than needed to change it again to 5.1. I don't remember but one of those roms was German.
Problem was that at some point my device was giving me some notifications under lock screen that it might be network locked ro something.
I don't have sim tray because i was using it like tablet.
Is it possible that it could get locked just by puting German rom and if there is a way to check this and to fix this????
Service told me it would cost me 40€ to unlock it if it's locked.

Unbranded from 3 network (bootloader unlock allowed no)

I recently bought the Xz on the 3 network (uk) and straight away wanted to get on aosp but this was shortly lived when my bootloader unlock status said no!!! Arghhh!!!
After moving from the HTC one X this was a massive disappointment as I loved the IceColdJelly Rom from Lord.
So I started to look into how to get around this and came across a solution online saying you need to network unlock the device officially from your network operator this would then change the bootloader unlock allowed status to yes.
Great but I cannot get this yet as 3 state you need to be over 1 month into the contract witch I sadly am not.
I then done a bit of thinking and wondered if I managed to get onto the official unbranded software from Sony via an official method I may be able to get round it.
To do this I:
Rooted for locked bootloaders
Installed twrp for locked bootloaders
Installed one of the roms for locked bootloader (353?)
Then plugged my phone into the computer and started up the Sony update software and this gave me the option to update my phone to the latest 434? Software (something I couldn't get while on the branded stock rom)
So update done I reset the phone from within settings and preyed my bootloader unlock allowed status had been changed from no to yes. But no it hadn't .
So what's the point of this post?
Well I'm sharing my way of getting the latest update from Sony officially if anyone would ever want to do it that way.
But also I'm opening this thread to discuss if anyone had unlocked their network limitations and found that it changed the bootloader unlock allowed status.
Thank you for your time
Hi.
I renewed my contract with Three and got the XZ, and like you was hoping it had the unlockable bootloader. I knew I had the contract I needed anyway and was prepared to do whatever I had to do if the bootloader was properly locked. In the end the only thing I could do was get rid of the phone and buy one that was Sim free and bootloader unlockable. I bought it from Phones for you and checked the bootloader status before I handed over any money.
When I had my "old" XZ, I put it up for sale and in the hope of getting it sold easier I had it sim-unlocked by Three and I flashed UK unbranded firmware. As expected, unlocking the Sim and flashing unbranded firmware did not change the bootloader status.
In short, the only way to run something like CM is to sell your blower and buy one with a suitable bootloader.
Ah well that sucks surely it's not down to the carrier to impose these limitations apon the end user? There must be a way around this even if it is contacting Sony, surely if I the owner of my phone want to. Unlock my bootloader it's for me to decide, not the middle man.

[Q] Anyone have an XSP from EE/Orange/TMobile UK?

If anyone has an Xperia SP from Orange, T-Mobile or EE in the UK do you happen to know if your boot loader is permanently locked? I know the phone's probably sim-locked but I'm less worried about that.
Thanks!

Yes, I have.
And the answer is probably.
Go to dialler, *#*#7378423#*#* ->Service Info ->Configuration. This will tell you if bootloader unlock is allowed. (it will probably say No) go back, then select SIM Lock and you'll probably find [x] Network 5.
This means it is simlocked, and you have 5 attempts left to unlock it.
However, you should be able to use a T-Mobile, Orange, EE and possibly a Virgin SIM in it.

Mine is from T-Mobile UK and yes it is sim locked and the bootload unlock allowed is a 'no' under the service menu.
Thanks all.
I only have an Xperia U at the moment, but it's sim-free and easily unlocked. I'm currently looking at upgrade options but I don't want to lose the flexibility I have with being able to flash custom kernels, etc. in the future if I get bored with the stock rom or, more likely, Sony decides to stop supporting it.

[Q] Unlocked xperia Z1 network locked because of flashing Branded Firmware

i have a Sony Xperia Z1. the model number is C6906. i bought it directly from Sony and its Unlocked . it was working on every sim card. But i flashed the C6906 firmware of the other branded network provider. now it's network locked with that network provider. it only works with the sim card of that network. when i put any other sim card, the dialog box appears and it tells to insert network unlock code. when i contact that network, they told me to get their sim card and use it for 90 days. then they will provide me the unlock code. why should i have to use their sim card for 90 days to get the unlock code, because my phone is already factory unlocked from sony. i went to 3rd party websites which provide network unlock codes. but they didn't find the unlock code for my phone, because that phone is not present in the database of that network provider. that means i can only get the unlock code from that network code by using their sim card for 90 days. but that network is not working in my area. please suggest how can i make it unlock again as it was before ? i will be very thankful
flashing FTF files will not affect the SIM lock status of a phone.
It will neither lock an unlocked one nor will it unlock a locked one.

i flashed the firmware of Rogers for my unlocked xperia z1 C6906, which was Branded Firmware. my phone was working fine with all sim cards. but few days ago i put the sim card of rogers, the phone automatically restart and also install some rogers network apps in phone menu. after that when i put other sim card, the network unlock code dialogue box appears. it means that phone got locked with rogers now. the rogers technicians said me if you flashed rogers branded firmware, then if you ever put rogers sim card in it, then device will locked to rogers even if its unlocked from sony.
well, not sure how that works as its the first time I ever heard that happening. Not that I don't trust operators but I often find they do not know what they are talking about when it comes to the kind of things we do here at XDA
But, if what you say is true, flashing another FTF will NOT help.

can xda developers develop any software for that ? so that the network unlock code dialog box disappear and phone reset with original factory unlock setting

that is not really what we do here. there are loads of websites for that, and rogers say they will give you an unlock code in 90 days anyway.

Flash using Odin loses sim unlock? SM-N920i

Hi, im experiencing some weird resets when i recieve calls, i reset the note 5 like 3 times and still the same, so i downloaded the NZ rom from Sam Mobile and i was wondering if this phone i bought is sim locked and i flash the new rom i will lose my unlock??
Is there any way to know if my phone is factory unlocked or if its locked whit what company?
Ok I find the question a bit strange but will answer to the best of what I understand. If you want to find out if your phone is unlocked just pop in another sim from any other provider and see if you get service or even if it even attempts to find it. If you get invalid sim msg or something similar you are locked. Also to answer your question to which carrier is it locked, that's obvious as it would be the carrier you are currently using. As far as flashing a rom from a different model note 5, I won't recommend without extensive research as you could brick your phone.

Sorry for my bad English, the phone is already unlocked but idk if was manually unlocked or factory unlocked because im from Bolivia and the Note 5 Says spark(NZ Carrier) and accepts any carrier, the problem is my fear of losing the unlock after the flash is this phone was manually unlocked

Carrier unlock a G920T permanently

Hi guys,
I need some clarification re: carrier unlocking and how it works. I recently purchased a carrier unlocked G920T, and I was going to start messing with custom roms/kernels and other goodies. My question is: Will the phone revert back to being locked if I do a factory reset or if I unlock the bootloader and flash custom roms?
I'm not a T-Mobile user, so I can't get another unlock code from them.
Thanks!!
The G920T has a carrier unlocked version, which is probably the one you have, not the T-Mobile one. Even if it is, usually a carrier unlocked device will remain unlocked forever unless it was unlocked using a different or hacky method, then there is a possibility that it will relock

Yeahh go ahead, mess with it. when it is carrier unlocked, the software doesn't affect it, unless it is a hacky method like @serio22 said, but there isnt such hacky method for the GS6 so have fun.
If it is a G920T (the T means it's from T-Mobile), then carrier unlocking is not a guaranteed state. I paid T-Mobile the full price to get my GS6 and they "permanently" unlocked it. Then after a OTA software patch all of a sudden it locked itself again and I couldn't use my phone for 2 days while they tried to unlock it. T-Mobile's new device unlocking uses a new system which has the phone "phone home" to their servers to check if you're allowed to use it outside of their network. It happened again when I accepted the Android 5.1.1 OTA. So...beware of T-Mobile's not-very-permanent permanent carrier unlocking.
I am living in india..
My relatives brought me the t model ( i wanted f model instead of i sold in india for quicker updates but got t model...lol )
Anyways,
The moment i inserted my sim, it worked like a charm so its unlocked at the moment.
I dont know how they made payment their or how it was unlocked, but the way used must be legit coz its still stock at the moment without root / recovery etc. .
I read humo saying it can get locked again...
My main question, what are the odds of that happening?
Also since i live in india, i wont be able to contact t mobile via phone/walk in, are there ways i can get it unlocked again?
I dont have the bill too if it matters
i believe they have an app that unlock ur device since that is how i unlocked mine. if not u can try to contact customer service online since u r not in US.
With device unlock app , will i have to pay for unlock my s6 g920t or it'll unlock my device for free.
I have an unlocked s6 tmobile from usa, i heard the flashing stock rom will relock the device.
If the phone will relock then how can i unlock it again?
I'm not sure about flashing a stock ROM relocking the device. Mine re-locked when T-Mobile sent Android security patches. This week I did the Android 6.0 OTA update and it has remained unlocked.
Hey guys! i have a factory unlocked version of s6 tmobile, my question is if i can flash the tmobile MM firmware . My model says "country: cellular south" and the firmware country says us tmobile, so i dont know if i can flash without any problems, (Sorry for my english it sucks) thanks !

You can't downgrade your bootloader so you'd have to pay to unlock it unfortunately

Got it done remotely!
I have a Galaxy S6 (SM-G920T) from T-Mobile. It was locked. But it has an "Unlock" app installed by default. I used it and phone was instantly unlocked! Fast, easy and free!
I used to live in the US for a year and bought a g920T. Since i had the requirements i Unlocked and came back to my country but because of a problem, I had to install a stock firmware and now the unlock is gone.
So i'm wondering, if someone with a unlocked phone made firmware backup, remove the IMEI, and send it online would it work? I mean, right now it works just fine, so i can backup my IMEI and ID and just restore it if needed.
Please help
