Xperia Z locked to "3" - How to unlock?

Hi all,
New to the Xperia Scene. I've rooted and unlocked HTC's in the past with sucess but I've come into contact with a XPERIA Z locked to the "3" network.
How would I unlock it & remove the "3" crap off it and flash a STOCK rom - Not really interested in a custom rom.
Thanks for any help given
EDIT - Just checked the Rooting Status info and it says Bootloader Unlock Allowed : NO - Am I out of luck?

You will need to get a SIM unlock code either directly from 3 UK or search for a service online (Usually they are about 15-20£) if you want to get rid of SIM unlock. Then you can,but don't have to unlock the BOOTLOADER (if you wanna flash custom ROMs not based on stock such as CM, AOKP etc you will need to unlock it but bare in mind that Bravia Engine 2 will be permanently lost unless you backup the phone). If you want stock based ROMs just root the phone using one of the methods found in xda. You can also checkout my youtube channel for a video guide on how to root and get custom recovery. Good luck

Yes - all UK carrier Xperias have non-unlockbale bootloaders. You are out of luck.
If you have any desire to go Custom on any phone brand, always stick to factory sim free unbranded. Period.

Thanks for the heads up.
I would just want to put my UK Orange SIM in and remove the 3 branded logo's etc. If I can't do this, I'll eBay the phone.

You can - get your sim unlock code, dial *#*#7465625#*#* in the dialer, input code then press unlock (this saves the trouble of finding another simcard. You of course need to use another sim card to test it - but hey, you wouldn't be unlocking otherwise )
You will then need to root and install a recovery - tons of threads about on that one. Then just flash any generic firmware (I'm using [NUT]'s Belgian Generic one) - ti won't have any carrier crap on it at all.
Alternatively, once rooted just use titanium backup to uninstall any stuff you don't like.
I've got a Three XZ as well and the bootloaders are NOT unlockable - there may be some joy with a KEXEC module if any of the devs get one to work, but until then you will be stuck with stock variants. I'm on the verge of ebaying myself for this reason.

If someone can unlock a 3 or any carrier bootloader without JTAG and Sony proprietary software then it will be a first.

Don't post questions in Development, thread moved.

[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.

What is de-branding (UK)

Hi,
I have noticed after reading a few threads that a lot of people in the UK are mentioning that they are going to de-brand their N4. How & why is this done? Does deleting all of the applications that came on the phone also accomplish this?
Also, will it make the phone any snappier after doing this and does this count as 'rooting'? Apologies for all the 'silly' questions, but I am fairly new to this.
Thanks,
Sam

I think was they are referring to is to root the device and this would allow you to put a stock firmware on and or remove the preinstalled software that can't be removed without rooting first.

You debrand a phone by unlocking it first (o2 sent me unlock code just an hour ago) , then flash stock firmware over the carrier firmware, then perform a factory reset, your phone will be debranded as if you purchased a sim free version, no carrier crap.
You do not need to root to debrand

Is the un-lock needed tho?, can't you just flash the current BTU if you dont need to unlock? Thanks.

I think you could do that yeah, don't think it would cause any issues with your phone functioning, only thing it would mean is your phone isn't completely de-branded as it would still contain your carriers sales code (I could be wrong here) just my take on it from what I've researched in the past

T-Mobile stock firmware on SM-G920T factory unlocked version

I recently purchased the G920T factory unlocked version on eBay, is it safe to Odin any T-Mobile stock firmware, any info will be appreciated, thanks in advance.

Once you above a certain firmware you can't go back. What firmware you currently on?

It is currently on G920TUEU3COK1 can I Odin to the latest T-Mobile G920TUVS3DOJC I understand that I can't go back but is it safe and will it function normally, thanks for the reply.

i have this same question because from what ive read 3COK1 is for Cellular South (aka C Spire). while the 3DOJC is for Tmobile, both under the G920t firmware. are you also on tmobile network with this phone?

What are the benefits of flashing T-Mobile firmware on the USA factory unlocked phone? I have this phone on T-Mobile and wifi calling works. I also get great reception. I assume this phone will get Marshmallow months before T-Mobile releases their build

Does this firmware that the device came with (G920TUEU3COK1) have any carrier branding or logos anywhere? Id like to switch if it doesn't have carrier branding

Are you getting LTE on it.

So I flashed the C Spire firmware and it asked for an unlock code. I flashed back to the original tmobile firmware and it is still locked although it was unlocked before, but the device unlock app says its ineligible for unlock now.
Anybody else encountered this?

Call t mobile customer service and ask them. They can adjust their servers and then the unlock app will work.

I'm sorry I misread that this a different model. I'd try to contact the user stifilz to unlock.

Were you able to get it unlocked? I plan on doing the same, flashing the unbranded to my t-mobile that is currently unlocked.

I'd advise that you dont.
To unlock it I had to flash back to the original tmobile rom. From the tmobile rom, the device unlock app failed in different ways.
After i called tmobile over and over I got it unlocked (like 2 hours of calling).
Hurts my heart to see all the tmobile bloat, especially when i dont even live in the US, but at least my phone works

Thank you, I guess I'll just sell this one and buy an international unlocked, glad to hear you got your phone working.

Anyone successfully updated this G920TUEU3COK1 US factory unlocked version to marshmallow? I have Samsung Pay, wifi calling, etc. all enabled on mine and would like to update, but also keep the unlocked non-bloated firmware.

Which method did you use to update the G920TUEU3COK1 US factory unlocked version? Does using the Tmo firmware risk un-unlocking the phone?

Using An AT& T Handset IN UK

Can this be done?
Does it work on all 4G bands.
Better still can it be flashed with a firmware to get rid of anything to do AT&T?
Ta

Been awhile since I posted this.
Can anyone tell me if it's possible to flash say a Cambodian ROM on an AT&T Note 5?

no idea. i believe i have an at&t note 5 based on what i've discovered after googling my bootloader / pda / csc / baseload version codes, although there's nothing on my hardware/software to suggest anything at&t related. whatever has been done to it means it's working ok for calls and data (except it always says '4g' in the notification bar, even when i'm in an area without 4g!)
I'm trying to find whether i can upgrade to MM (or Nougat when available) without destroying my phone

Does your note 5 have at&t branding on the back?
When you go in sotfware info what rom have you got?
have you ever had any ota updates?
what sim card are you using?
Thanks

Only got it about 2 weeks ago from HK via ebay. No reason to suspect anything until looking at updating to MM. My model type in 'about device' shows as SM-N920F which, after some searching around, doesn't exist. Then unearthed the phone is rooted and possibly from USA via a China unlock process etc etc. Anyway, in answer to your questions:
1. No AT&T logo
2. Software looks stock (i.e. no names that would suggest custom rom)
3. No OTA updates (but then I'm rooted so wouldn't expect any - I believe)
4. 3 (three)

I was looking on ebay at a 64gb but they all seem to be at&t refurbished. Whatever that means.
I was told an at&t wont update with their sim being in the phone. That's why I asked about yours.
Do you have a link to the one you got?
