I just received my Sony D6603 Xperia Z3 from my carrier which is Rogers. Is there a way to fully unlock the device as if it was purchased as an unlocked version? I've tried searching for answers, but only came up with how to unlock the bootloader and rooting instructions. Unless, if by doing those methods, will fully unlock my device including SIM lock. Any help and insight would be greatly appreciated.
Depending on Roger's terms you should be able to have them unlock it. Appears you have to wait 90 days though.

Loving this one:
Why do I have to wait 90 days before I can unlock my device?
Your device has been optimized for use on the Rogers network. You may find that some settings or features do not function properly once the device is unlocked and in use with another carrier's SIM card. We want to ensure that you've had the chance to experience the full capabilities of your device on the Rogers network before making the decision to unlock.
Rooting and bootloader unlock will make no difference to SIM unlock.
The two issues are separate.

If I unlock the SIM on my device via a code, will it still be unlocked even after re-flashing my device's firmware?
Because I just checked to see if I can unlock my device's bootloader, but I'm not able to at all. Maybe I will be after getting it unlocked by Rogers themselves after the 90 days.

Once your device is sim free (using code) it will remain unlocked no matter what you do

Please re-read what I said. Bootloader unlock and SIM unlock are two separate things. One does not affect the other. It does not matter what you do to one it will not change the status of the other.

Yes, I understood what you said. What I meant was, when or if I get Rogers to unlock my device, unless they're only unlocking the SIM on it, hopefully I'll be able to unlock the bootloader as if I originally purchased it unlocked to begin with. Because when I checked my device's service menu, the status on the bootloader is that it cannot be unlocked using Sony's official method. If I had purchased an unlocked device instead of getting it through Rogers, the bootloader unlockable status would be different, correct?
When I get home, I'll try and see if I can still unlock the bootloader un-officially using Flashtool, unless for some reason that method won't work at all and my bootloader will not be able to be unlocked at all currently.
Edit: All I basically want to accomplish in my new device is to have root access to it. My previous device was an Xperia PLAY which was also purchased originally locked from Rogers. But after fully unlocking it using the Omnius client, I was able to unlock it's bootloader, flash DooMLorD's kernel and get root access to it. Because all the tutorials I've found on how to access root on the Xperia Z3 involves having the bootloader unlocked.

Probably, but some carrier free devices come with a boot that cannot be unlocked and some devices that are from a carrier can be unlocked. SIM free or SIM locked does not imply the bootloader can or cannot be unlocked.

There is no unofficial bootloader unlock for this device. Its done through sony's official method or not at all.
If Rodgers unlocks the sim for you it will not affect the status of the bootloader at all, unless you ask them to do it and they agree.
To get root access you do not need to be SIM unlocked. The only way to gain root acces on the Z3 currently is to unlock the bootloader, which you cannot do even if Rodgers SIM unlock it
The xperia play is a legacy device and there were unofficial ways to unlock the bootloader. That has not been the case with all new phones for a couple of years now. I believe (Correct me if I am wrong) that the xperia NEO was one of the last to come with an unofficial unlock (The test point method). My old Xperia T was one of the first to come that had no unofficial unlock and the only way to do it was via Sonys unlock site.

That may be coincidence, I believe that Sony made a tactical decision to stop unofficial methods by allowing some devices to be unlocked officially. This saw an almost immediate stop in devs working on unofficial unlocks as you could always get hold of a device that could be unlocked officially and for free. They basically took the need of an unofficial unlock out of the equation.
If Rogers could do that, it really makes me wonder what kind of tool/program that they use to accomplish this.
Probably something similar to Emma or just fastboot and adb. I really do not know that. The problem is they know the keys, without them it needs a good dev to find a vulnerability and write an exploit. That takes time and skill. And since there is an official method there seems no need to spend that time, as people with that skill just get themselves devices which can be unlocked
My 3rd day now with my new Z3 and I'm really missing having root access.

Will SIM unlocking allow you to delete the Rogers apps?
Also, I noticed my phone doesn't let me hide apps, though most people seem to have that option... is that a Rogers thing or is there something wrong with my device?
Sim unlock has nothing to do with root, so sim unlocking will not give you the ability to remove system apps.

What i have done already to my device as soon as i got it, before even turning it on for the first time, was use Flashtool and flashed it with the Global Generic Firmware to get rid of the Rogers branding on it. I was able to disable most of the built in bloatware that originally comes with it.

Will doing so essentially wipe my phone? Unfortunately I've already downloaded all my apps/customized it how I want otherwise, so I'd like to avoid that if possible. Sorry if this seems like a stupid question, I'm new to Android.

I am completely clueless of what bootloader is and after some googling, I think that it's the locking of a phone's network to a specific company like verizon, at&t etc. But, here in India, we don't have such contracts, so do I need to unlock bootloader before rooting my phone? I previously had galaxy ace and there was no mention of bootloader even when I installed all sorts of custom roms.

you just won't get root if your bootloader is locked
Unlock it for root, CWM, ROMs , etc
No, a bootloader doesn't do what you assumed, it just restricts your devices from any alteration by giving you limited access. Region locked or carrier lock is a different thing.
Thanks all, one more thing, if I unlock bootloader then can I get my warranty back?

NO, you won't. When you apply for the code on Motorola site you lose your warranty. Even if you somehow manage to trick them, Moto G will still show status code as 2 (meaning relocked) instead of 1 (locked) or 3 (unlocked). Anybody feel free to correct me if I'm wrong.
Well, hello to everyone. I bought Sony Xperia Z3 and bought code to unlock it for all sim cards and it works. When i visited Sony's site for unlocking bootloader i came across this post:
In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.
Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
Well, my device cannot be unlocked because it says No..
so what can i do to unlock it?

For your device it is not allowed, so you can't unlock the bootloader.
/I've read some threads about trying to unlock the bl although service says "no" on other Devices like z Ultra:
It's not impossible to unlock the bl with official method if you know your device earlier had status allowed "yes".

Wouldn't bother me so much but my Z3 has a horrible bug where it doesn't work with the bluetooth in my car without rebooting first every time. Was hoping to install CM12.

It's not that I have any major issues with Sony roms, I'd just like to be able to flash other stuff in the future, should I want to.
I'm still going to keep the Z3, such a nice phone, nothing else really comes close to it for me yet. Maybe the M9, but I just got the Z3 for £260 from o2 and had it network unlocked, probably have been looking at least double that for the HTC.
You can still root the device and customize it. Tools like the XPosed framework are great at modifying specific parts of the ROM.
But to confirm: you're stuck. You can't unlock Sony's unlockable bootloader. I've heard of people trying to unlock it, I've never heard of a successful case.
Enjoy the phone, it's among the best available right now (imho).
Just got mine today and it looks like the value is NO even I have allowed OEM unlock in developer options. A quick search showed if the value is no, you will never be able to unlock.
A very bad news for me. A few questions:
1. is that really not possible to unlock it? Who shall I contact? Sony or Carrier?
2. Can I root with locked Bootloader? And flash TWRP and ROMs?
Thanks

No, there is no way to root or unlock your bootloader if it reads 'No' on 'bootloader unlock allowed?'

Yes it is.
On older Z series it was possible to root on stock kernel and therefore Unlocking bootloader wasn't required for rooting.
Since Z5, they implement Sony RIC and DM-VERITY, which prevents modification to system and therefore root.
To root, we need a kernel supporting root inside the boot image.
We can't flash any kernel other than stock (signed by Sony) on locked bootloader.

If you've got the Bell Z5 then you're in the same boat as myself. No way to unlock the bootloader, thus no way to root, meaning I can have ZERO fun with this device. I even paid Bell for a SIM Unlock thinking it might trigger the bootloader unlock option to change to 'Yes' Allowed, but no such luck.

Thanks for sharing with me. You are very knowledgeable. I bought from a guy who bought from Bell. I doubt Bell will actually support my request. I will try to use it for a bit and resell if I cannot live without root. I have been using root devices since HTC G1.
All phones from carriers usually have locked bootloaders, except for nexus devices. This is why you never buy from a carrier if you want custom roms.

It's worth trying, just see how they react
I got pretty used to root too, since my first Android a galaxy S i9000 lol
Though, when I bought this phone (my second Sony) I decided to use it without root too and in the beginning it was a bit of a struggle but later I didn't miss it at all.
I only unlocked my bootloader after a few months, just to use another kernel.
You can disable most (if not all) bloatware via settings.

Locked Bootloader, Config Says "No" Can't Unlock, But Have Root... Am I stuck?
Hey everyone,
Well, I had to pull out my previous phone, my Tmo D6616 Xperia Z3. I replaced it when the battery was all bloated and could explode, etc. I replaced it with an LG G5. And, I have the horrible GPS issue with my G5 that just doesn't work well at all. This bugs me. I travel with my family enough that I use it and has caused some wrong turns, etc. I want to replace it, but don't see any good deals in my situation since I have no number to port-in or a new person to bring on the plan.
So, here I am checking on what I can do with my Z3. I've replaced the battery, got a new case, and also replaced the screen protector... just like a brand new phone, except the ROM is really outdated. It is currently on the latest OTA from Sony, Android 5.0. I did check to see if there is a more recent stock ROM and there isn't.
I want to install a new ROM, in which I should be able to backup the TA partition since I am rooted.
When I do the *#*#.... code, then check to see if the bootloader can be unlocked, it says no. Because of that, am I out of luck?
Am I able to use root to unlock the bootloader and install another ROM?
Same question here...

I also want this answer.
If it says "no" to unlock the bootloader, then you can not unlock the bootloader.
You can, however, use root and recovery.
Check out https://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056. Just stick it to xperia Roms. Search the forum, I think Marshmallow is the latest.
As far as I know, other Roms than Xperia are not recommended for a locked bootloader. But there are other, xperia roms, for a locked bootloader Z3.
Good luck.

I was able to get recovery installed, thanks for that. I am not so sure about the MM rom, however. I haven't seen one for the D6616. That would at least make it a little better to work with.
I was under the impression the device I ordered off ebay could be bootloader unlocked (apparently verizon pixel 3a), but can't seem to figure it out myself, and i'm starting to think its not possible. If anyone can unlock the bootloader, I am willing to pay.. If not.. :RIP: :crying: Hopefully this doesn't violate the rules, didn't see any.
Unlocking the bootloader on Pixel phones is pretty easy. You can use the guide here to unlock the bootloader.
You will need to use ADB. If you are not familiar with ADB, you can use the guide found here.
I'm assuming that you want to unlock the bootloader so that you can root your Pixel. I used this guide.
I reread your post and noticed that you bought a Pixel that is carrier locked to Verizon. Usually, unlocking the bootloader of a Verizon phone is either not possible or difficult. The information that I gave you is for carrier unlocked Pixels. I haven't had a carrier locked phone in many years so my memory of what is possible is probably a bit fuzzy.

The phone is not carrier locked, but it was a verizon phone previously. Thanks for the links, and basically my problem I run into is the Greyed out unlock option in developer settings.
Have you tried doing a factory reset and then allow the phone to update over wi-fi?

Remove the sim card, do a factory reset, and then go through the setup without the SIM installed. This should allow the OEM unlock to be toggled. Its worked for multiple other people.
Did you switch from Verizon to Tmobile? It appears from what I'm reading that TMO sims are downloading carrier specific settings/options which block the unlock switch.
Regardless of whether you use tmobile or not, the above method *should* allow you to unlock.
