[Q]Unlocking Bootloader - Do I have a SIM unlocked phone???

I have a rooted x8 running gingercruzt 8.4.
Every time I turn on or reboot my phone, after I insert the regural PIN code another code is asked: "SIM network PIN unlocker" or something like that.
There are two options under the gap: "Unlock" and "Dismiss"
Although I press "dismiss" all the time, my phone is fully functional.
I've bought my phone with a one year contract from a different market(carrier) than I use at the moment.
As I remember, when I had the official ROM, I had no such messages, although the first time I rooted my phone, it wasn't fully functional(I couldn't receive any sms).
I'm not 100% sure about that, because it was about 6 months ago, and I instantly flashed a custom ROM.
So, my question is if my phone is SIM unlocked.
I ask because I am about to unlock my bootloader and I don't know if that fact could affect the funcionality of the phone after unlocking.
And if not, if it could affect the unlocking process.

You should check the unlock tool and see what sim lock you have before unlocking the bootloader but I would imagine your phone must be unlocked if u are able to use a different sim card unless you live in a country where they dont lock there phones? Also have you tried flashing back to stock to see if the sim pin message comes up as I've never had that message show up on gcr b4. Also what tool did u use to root I always use flashtool and never had no problems.

If you want to unlock the bootloader just use the s1tool.. this tool i can say is very safe cause it's only read the locked or not status it won't do any harm.
Take a look if u have big "R" or small "r" and have the semc xxx certificate if u have any other than that you shouldn't unlock your bootloader (you could unlock it but with bigger risk).

I actually couldn't understand what semc is when I was reading the guide. I could use some help with that too...

I didn't try to return back to stock ROM. I've used superoneclick for rooting. Sould I repair my phone with PC Suite and root it again with flashtool to see the results?

If you say dismiss, it means your phone isn't SIM unlocked. With s1tool you can easily see what's wrong with your phone. You are able to unlock the bootloader, but for safe return to stock rom before u try it.

+1 no problem with rooting using Superoneclick. I used it too, and now i run Alfs kernel without problems.

Although I choose dismiss every time, and I use a diferent carrier than the one that owns tha place I bought my phone(I bought it from a "wind" market and I use "cosmote"), the phone is fully functional.
Correct me if I am mistaken, but it souldn't work with another carrier than "wind".

I know it's possible to use cosmote instead of wind (in your situation)
Try to unlock BL and see what happens. Do you tried to identify with s1tool?

Well, if its unlocked via imei, Im safe to unlock the bootloader... at least thats as far as I could gather by all the info scattered around.
To help narrow down the possible unlock method used, I can add that whenever the phone is rebooted, and there is a sim from a different Service Provider than the "original" one, it asks for a network unlock code. By tapping "skip" the phone then boots up and works just fine with any other Service Provider's sim.
This leads me to believe the phone was unlocked by other means than IMEI. And hence, all hopes of unlocking the bootloader are obliterated.

Well, I still don't know what method was used to apply the simunlock, but, I was able to find out that my bootloader is unlocked.
So, that's cool :cyclops:

[Q] Flashing ROM + Bootloader Xperia T

Hey guys, I am fairly new to the android phones, (recently came from an iPhone) but I had heard so much about the freedoms with the Android os so I decided to switch.
I purchased the Sony Xperia T (LT30a) locked on the Bell mobility LTE network. I have really wanted to unlock the bootloader, so when I went in to check it said "Bootloader Unlock Allowed: NO". after some searching I read that it was my carrier preventing the bootloader from being unlocked, and that if I followed the following simple steps, it would change the message to :"Bootloader Unlock Allowed: YES". so here is what I did:
1. Flashed a Generic firmware to my phone (ICS it was a uk generic) which then changed my model number in "About phone" from LT30a to LT30p and removed all the bell branding.
2. Using an IMEI number, i was able to get an unlock code and unlocked the phones sim card to work on any network, and have tested and it does work.
the problem I am having is that even after doing this, the bootloader is still "locked" and can not be unlocked. I have taken a look at the methods for the test pin, but that involves removing the battery to view the motherboard, which sucks because this phone the battery is not removable. if anyone know a free or paid way to unlock the bootloader on the Xperia T LT30a or LT30p models, please let me know! thanks.

I dont know where you read that, but it is wrong and there is no way to change that message.
If it says no, then your bootloader can not be unlocked.
Its not Sony's fault, its not googles fault, its Bells fault for being a dev unfriendly provider.
Test point method will not work even if we could remove the battery, that loophole has been closed in 2012 devices.

ok well thank you very much! I guess my next question is.. is there any way at all to install a custom ROM such as cyanogen mod 10 ? or if you know of any better ones while my bootloader is locked?

You can only install stock based custom roms because you wony be able to flash a custom kernel with a locked bootloader. Therefore there is no hope for cyanogenmod, AOKP or MUIU
There are several in the Dev section to choose from, ranging from early ICS firmwares to the latest JB firmware.
I dont recommend Roms (Even my own) as choosing a rom should be a personal thing, but the I am currently on Timin8rs rooted and deodexed JB rom which you can flash.
You will need to root your phone in order to flash a recovery, then flash the .zip for the rom using that recovery.
Find all instructions for doing that in the All in one thread. Its the first thread in the Q&A section.
good luck and if you need extra help after reading up on what you need to do then ask. But remember to read up first!

thank you very much! hopefully sometime in the near future they come out with a way to fix this problem, and believe me, I do not blame sony at all for this

Sorry for the double post! But I just wanted to say, that if anyone needs help testing different roms and/or ways of unlocking a locked bootloader, I do have a sim unlocked xperia T and just wanted to throw this out, but if sony does not "perma lock" the bootloader, and if it is infact the carrier, then would this not prove that it is sonething in the firmware? I spoke with my sister who is a manager for a bell store here, acording to her, Bell is not authorized to open, or attempt to fix this phone, it is simply sent to sony for repairs.. Just makes me wonder because if Bell can not open the phone, then they must have used some sort of software.. I have always thought of software as "semi-permenant" that it can be reversed , and that its only a matter of figuring out how to reverse 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.

[Q] Help: Sony Xperia Z1 says cannot unlock bootloader

How can I install a custom ROM without an unlocked bootloader?
My phone says its bootloader cannot be unlocked

Mine too , it's must to be a solution to unlock the bootloader...

No, there is no solution
If it says it cannot be unlocked then it cannot be unlocked
Look in the development section for stock based custom roms that can be installed with a locked bootloader

To my experience it needs to be sim unlocked first in order to be bootloader unlocked. In a Xperia Z it said it couldn't unlock bootloader, i purchased unlock code, got it unlocked and then reflashed stock image. After that the status on "bootloader unlock allowed" was changed to yes.

Please provide proof of that, because this has never happened before and would be fantastic news
Also, some sim locked phones can have bootloaders unlocked and some sim free phones have bootloaders that cannot be unlocked. SO your logic is wrong.

Can't provide proof as 1) the bootloader was already unlocked 2) I don't even have the phone anymore.
I don't know if you find my logic right or wrong it was what happened to MY experience with one phone.
I'm pretty sure devs can give you a technical explanation about why it can or can't happen.

OK thanks.
I know what the devs will say. They will say it cant happen. This has been talked about ad infinitum across various xperia devices.
Also, if your boot was already unlocked then how did you know the status changed?
Thanks anyway.

When i got the phone (telcel mexico) it said the bootloader was not allowed to be unlocked.
I purchased an unlock code. Entered the code, unlocked the phone.
I flashed an upgraded FW via FTF
typed *#*#SERVICE#*#* and boom bootloader unlock statys changed to yes
That's how i know the status changed. So basically that's my story. I thought it could work with every device.

@gregbradley maybe the sim unlock method really works to change unlock bootloader status YES..bcs it works for some sony device, and we need to test this on Z1.
http://forum.xda-developers.com/showthread.php?t=1896553

There is nothing in that thread that confirms this. Plus the test point method to unofficially unlock the bootloader was stopped by Sony nearly 2 years ago.
But please, delve into this again if you want. But trust me it is a dead end and does not work. If it was easy as sim unlocking and flashing a ftf do you not think that would have been done by now.
Some seriously good devs have been working on this ever since the test point method was closed.
