[Q] Sony Xperia U network unlock

It's probably a n00b question so apologies in advance, but if I root / bootloader unlock and Cyanogenmod flash an Android phone that's locked to a certain network, will that network lock be removed along with the official default Android ROM? Or is the lock at something like a BIOS level (or whatever the smartphone equivalent of a BIOS is)?
I bought a pre-unlocked Xperia U about a year ago that I've been using on Vodafone and had to return it under warranty (got stuck in a boot loop despite the fact that it's totally unmodified, not even rooted, honest!) and the replacement they sent back is locked to Virgin Mobile. They're telling me that the phone I sent them was originally sold to Virgin in France and locked to Virgin before I bought it, and that they've therefore fulfilled their responsibility. So I'm just wondering now about unlocking, and I've always been curious anyway about how / if bootloader unlocking, custom ROMs etc are related to network unlocking.
Thanks in advance for any help you can provide with this!

well u can unlock it.. by getting the code from sony..
It will also unlock the ph..'s Sim lock..
Or ask the sony officialy for this.. they'll provide u every info required.
But unlocking the bl will do the job for you to be sim free
But do double check this from google too.
Also before unlocking pls make a backup as it will wipe everything from the device.
Just unlock and don't flash any custom kernels.If you want to then do it carefully pls with a backup and a copy of flashable stock rom.
Flash custom roms based on stock kernels
Hope this will answer the query..

Thanks for your reply! I spoke to Sony and they just told me to contact the network (which have done and they're wanting to charge me a fee to provide the unlock code). So to clarify, if I root the phone and unlock the bootloader, the network SIM lock will also be removed?

Not by rooting but also i guess not even by unlocking bl..
how much are they charging exactly..
i'll try to find the link for this
Also check this that how many times is the code applied for unlocking..it should not be 0
use this *#*#7378243#*#* in dialer
then service info sim lock

When I dial that number, the number just disappears. What is it for? They want £15.32 for the code. Should I just pay them and forget about trying to remove the lock?

Sorry the code is this
*#*#7378423#*#*
check the sim lock counters should be zero in all..
if zero then once u can try googling the code for unlocking if they work then it's great.
if not then it would be better to pay them for this as its a bit risky..
and are u using virgin's network??
As it's cheaper what they areaskingfor i guess.

[Q] SIM unlocking the T-Mobile version of the Xperia Z3 (D6616)

Hi guys, well the thing is that I'm planning on getting the T-Mobile variant of the Z3 (D6616) but I would like to know if there is a root method for Lollipop?, since the update is already out. I have have searched all over the internet looking for answers but I couldn't find anything (only for KitKat; I know the LP update was released almost 2 weeks ago). I don't if there's something else necessary (apart from getting root access) to be able to SIM unlock this phone, I don't care about custom ROM's, kernels or any other kind of mod that requires the bootloader to be unlocked. Like I said, I just want to SIM unlock it and use the root access for Titanium Backup and maybe disable or delete the T-Mobile apps. Thanks in advance.

Yes there is root for it but I doubt you will be able to sim unlock it unless you pay full price for it from tmobile and us the sim unlock app that's on the phone already.

That's the problem, because there's no way to officially get the Z3 from them (they only have the original Z and the Z1S and the only way to get one is from eBay) and I'm not a T-Mobile costumer. I would like to know if it's possible to get it unlocked with a third party unlock service.

I just bought one for use on AT&T and I'm also looking to sim unlock. I'll update when I find out more.

If you are one AT&T better to get international version as the 700 Mhz LTE band is different from the TMO version's which is TMO specific. (Band 12)
For indoor use that makes a big difference in signal.
The low bands have better penetration. I am on T-Mobile so for me it's an advantage to use the D6616.
The D6603 (international) supports AT&T 700Mhz in addition to the others.
As for unlocking TMO version, for me I had to call TMO as the app did not work. They will only unlock after 40 days of device use on your account. It's done over the air...
So give it to a TMO customer for temporary use and unlock assuming IMEI is not blocked.

hi
hi, already posted same reply in another sim unlock thread.
i have a d6616 tmobile version and bought the unlock code, non able to input the code, and not able to unlock with the stock app, dual recovery installed and rooted already, is there a way to put the simunlockapp.apk in the system and then using titanium backup pro, to make it internal so after rebooting, simunlock code prompting?
or to flash a rom that prompts the code
or is there any metropcs z3 rom that surely can be flashed even with locked bootloader to tmobile version?
any help
than you very much indeed

Hi, I'm in the exact same situation, Bought a Tmobile Z3 through Ebay, didn't know it wasn't possible to unlocking it by buying an unlock code... so I did, now I have the phone and the unlocking code for nothing... some help here please? thanks in advance.

Same boat. I bought a brand new one with film on it. But it was a phone only, no box or accessories. IMEI was a separate sticker (4 pieces). I tried to unlock a legal way but T-Mobile rep told me it's not in their system. It has printed T-Mobile logo in the back. I also tried official unlock app without success. They advised me to call Sony directly and ask what carrier it belongs to lol. Great phone, much better battery than G3 but unlocked phone is a must. I decline phones with 2k screens. I can't see no difference between Z3 and G3 screens.

Is there any way to unlock my phone.

I bought a oneplus 7 pro without paying much attention to the fine print. The phone apparently has an IMEI issue and it locked to T-mobile. I want to use it in UAE, is there any way I can unlock it and use it here. It has already been shipped and I can't cancel my order.
PS: Can I unlock my bootloader and install custom roms.

Dinner... You should be able to unlock the bootloader and root it, but it will remain Sim-locked to t-mobile. There are services online that will unlock it from the t-mobile network.

I think there might be a way actually. Haven't personally tried it, but many have said it works. It looks like on the the Android 10 Developer Preview 3, you can actually bypass the token, and unlock the bootloader! I'm not sure if the phone would still technically be SIM locked to T-Mobile (if you wanted to use another carrier), but honestly have no idea. But at least from what it sounds like you should be able to unlock the bootloader, and flash custom roms.
Check out these posts, and the main XDA article that has instructions:

You still need an unlock token from OnePlus to unlock the TMO model, even on global firmware. It takes about a week from request to processing. You can get around it by flashing the A10 DP3 OTA, and it won't check for the token.

Help T-mobile unlock sim

Hi. I have my 1+7 pro from ebay, I live in Europe. Can anyone help me unlock it (is locked on T-mobile) only having the IMEI as I have no clue about the account or holder name.

Same problem as yours

Sorry missing part of the stuff. Need to use a beta version after that to unlock. The are the old instructions are in the link below; the concept is still the same. Anyone can chime in if I'm incorrect.

I don't understand why you guys would buy a TMobile version when there's a global unlocked version available.
There's a guide on here though for a sim unlock. Gotta flash developer version first

This process does not unlock your carrier
This process only opens the boot lock

If your device is locked to this sim for iron
There is no solution to opening a provider
If it could be opened
The network lock
It was good for a lot of people
Once the modem is locked there is nothing to do if it is
Also, the network lock cannot be decoded
Bootloader
Easy to open
Convert to international version
Then update Android Q 3 through a local upgrade
DP 3
fastboot OEM unlock
A local upgrade way to get back to the old rom

Best root method - T-Mobile Oneplus 8

Hello,
I'm seeing quite a few different "methods" or instructions for rooting. I just picked up my Oneplus 8 today with T-Mobile, it's on a payment plan if that matters for SIM unlock, etc.
What's the easiest method to rooting the device? I use Adguard and want it to run using the "root" method which is better, per their support (which is why I bought this phone). My current build (which reports up to date) is 10.5.10.IN55CB
Thanks to all in advance
P.S. Any negative effects? I'm reading mixed reports of loss of LTE/Wifi.

You can only root after sim unlocking the device. After that you would apply for an unlock token from OnePlus, and after a week you'll be able to unlock the bootloader (which will wipe your data) and then you will be able to proceed with any of the root guides posted here.
There is a sim unlock thread in the guides section here, though the person offering the free service is heavily backlogged at the moment. You may have better luck asking TMobile on Twitter for a permanent unlock, though they are very stubborn.
Once your device has been permanently unlocked, you would toggle unlock bootloader in developer options, enter fastboot and enter a command (follow the OnePlus unlock bootloader guide somewhere on Google for this)

TMobile will officially unlock it after paying it off in full (and I think be on the network for x number of days) but there have been cases where they have unlocked the device prior to it being paid off, ultimately it depends on the representative you speak to

Look on our website there is someone who can SIM Unlock for you, without you having to pay off your phone first. From there you can request from One Plus to send you your unlock bin. This is how I went about it, I was up and running with an unlocked bootloader in 1 week. Might want to donate if possible:highfive:
