[Q] non unlockable boot loader - Xperia Z3 Q&A, Help & Troubleshooting

I have rooted my Z3 today and it seems I cannot unlock the bootloader on this device, it says no on service menu. Is anyone able to suggest another way to get past this? Am I correct in guessing it's EE (UK) who supplied the phone who decided to lock the bootloader?

Rogers D6603 Full Unlock

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's something I didn't know, I've always thought that when you purchase an unlocked Android device that the bootloader would be unlockable, good to know!

So they can apparently change the unlock-able status of the bootloader themselves?

So basically, unlocking Sony devices unofficially, stopped around the same time Sony Ericsson became only Sony?

Yes, there have been some posts that some people have managed to do this with some carriers, but I am very sceptical as to this actually happening.

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.

Not if you tick the box to exclude data on flashtool when you flash it

Is there some sort of beginners guide/explanation/walkthrough you can point me towards? I've never had an Android before, so I have no idea what I'm doing and I don't want to screw anything up.

D6603 Bootloader unlock allowed set to No

I purchased an Xperia Z3 (D6603) in November on contract from Vodafone UK and today I decided to unlock the boot loader. My phone is on contract but I got it SIM unlocked. When I opened the service menu, it says "Bootloader unlock allowed: No".
Is there any way to unlock the bootloader?
No

Not even after my contract expires? Is there no way at all?
No
your out of luck for time being, however soon enough you will be able to run custom roms as long as the stock kernel is used so its not all doom and gloom.

[Q] T-Mobile's Z3 debranding for sim unlock.

Hi everyone. I bought a T-Mobile's Z3 used by another guy. He shipped it from the U.S but i'm not there. The thing is: He bought a SIM unlock code but T-Mobile won't let me introduce it because they only let you unlock the phone through their app. The question: If I debrand the phone by flashing the global/international firmware would it let me introduce the code? . I hope you can help me.
I don't think you can just cross flash, at least that is my experience with other devices as well. Also no way to bypass the SIM lock as there is no boot-loader unlock or r oot for the TMO Z3.
As far as I know its an over the air unlock and there is no option to even enter a code... when the app did not work for me I called TMO and they unlocked it within an hour, as I am a current customer.

Oh well!. So the only hope is to wait for some root method. Thanks for your answer :good:

Root and bootloader unlock have no effect on sim unlock. They are completely different things
It depends by phone/carrier implementation I guess, for my Sprint LG G2 you could bypass the simblock using a method that requires root. In the HTC M8, boot loader unlock with Super CID could achieve SIM unlock as well.
You probably are correct with Z3 though.
Im in the same boat, bought a used z3 and tried to unlock using device unlock app on phone, Failed. I bought an unlock code but there is no menu to input unlock code. If we flash global generic firmware, will unlock code pop up?

Has anyone tried this and been successful? I attempted it this morning but got errors and flash aborted.
Edit
Guys keep trying the unlock app. I almost gave up and tried it one more time after a factory reset. Went through the setup menus. No Sim card, WiFi through my old Xperia z, turned on my location. Opened the unlock app and applied for permanent unlock and BOOM.... Unlocked.
Don't know if any of what I did made a difference but try it if you want.
Best of luck to you all.

Bootloader Unlock Allowed : No

My phone is through Bell (which I bought outright). Without an unlocked bootloader that means I can't flash custom kernals correct? Is there a way to get around this? Why is my phone's bootloader unable to be unlocked but others are? Any help / clarification appreciated.
If it says "Bootloader unlock allowed: no" then there is unfortunately no way to unlock the bootloader so you can't flash a custom kernel or most of the roms!
this can't be changed except you replace the motherboard or buy another one :/

Only workaround is sell that xperia z5 and buy another.

cyanogenmod maybe?

ok so I have got a moto g pure (XT2163DL) with a tracfone bootloader and ive accepted that I cant find anyway so far to get my unlockable bootloader unlocked. I have looked and tried everything I could find without using a paid service which is probably what I need to do or just get another phone but first I have one more idea but I just dont know if it is even still possible or not. Can I use the cyanogenmod installer on my phone and unlock my bootloader and then switch back and keep an unlocked bootloader? Im running android 12. My oem unlock switch is not greyed out and it is set to unlock and even though I have tried using fastboot oem unlock and it said it was successful , it wasnt really unlocked afterall. motorola site just says my bootloader cant be unlocked. Is this a viable option?
