Unlocked my bootloader for nothing - Xperia Z5 Q&A, Help & Troubleshooting

Peace be upon everybody, and good morning/evening
Last night I remained using my PC for a whopping 9 hours of work to figure out how to unlock my E6633 bootloader - and I finally figured it out.
The whole process was bumpy and the Sony Mobile Developers tutorial didn't wholly work out, but it had some vital info for the process. I had to unlock the boot loader using the Flashtool (thankfully), and I had some lack of luck at the beginning, which involved a journey to find the lost driver for my Z5, and to install it in the Device Manager (took some time). And then I took a "detour", since facing another roadblock, by creating a folder in C:\Users\<User>\.flashTool\registeredDevices named by my devices code (that appears when you enter adb devices in cmd), then inside of that folder I've created a .txt named ulcode.txt which contains the serial code provided by Sony Mobile to unlock your boot loader. And I've gotta tell you, it was all a pain in the bass.
More frustratingly, this whole procedure has resulted in zero luck with rooting the goddamn device (thanks Sony), and now I'm stuck with an unrooted bootloader-unlocked device . I'm sure this requires taking another detour. I've failed in every way I know to flash the modified stock kernel for some reason. I've tried cmd to flash the kernel and it comes back with FAILED <Remote: command not allowed>. I've also tried Flashtool to root it directly, and it turned out to be non-working as well.
Now, I'm not going to complain about this whole situation, even though I'm recalling how easy rooting my good old Galaxy S3 was. I'm now looking for a solution for that last tiny bit of the puzzle, and I'm sure there are other fellow members who are facing the same hitch.
Cheers .

Is oem unlocking ticked? It sounds like your bootloader is still locked.
All I did to unlock mine was type the command Sony provided with the unlock code and unlocked it with fastboot, took maybe 10 seconds?

After unlocking the bootloader does the phone reset to factory settings? Just to make sure that you succeed unlocking.

Go to developer options and check if oem unlock is ticked

This difference in rooting experience that the OP had with the GS3 and now with the Z5 raises a question in my mind. Is the modding community more focused on popular devices? This is often a deal breaker for some people. If the 6P or the GS6 gets more ROMs and mods and faster root exploits than the Z5, then I myself would prefer those devices over the Z5.

It is indeed ticked and I'm positive that the bootloader is unlocked.
Yes I tried the easy way of doing it with cmd but it just didn't work out. Kept returning with FAILED <Remote: command did not succeed> and that's why I resorted to the other way of creating those files in the flashtool folders (as explained in the OP).

I went through the steps in that thread and without any problems until the part with
Code:
fastboot –i 0x0fce oem unlock 0xXXXXXXXXXXXXXXXX
I have checked the recognition of my device by entering fastboot devices and it recognized my device successfully.
The X's above being the code provided by Sony, the cmd window (of minimal adb and fastboot) returned with
Code:
FAILED (remote: Command did not succeed)
Although, the step prior to this one which is to unlock the bootloader using Flashtool has succeeded.
It's really mind-boggling...

As far as i know that unlocking bootloader will reset ur phone to factory settings.
And not sure but i think you need to remove a number from the code sony sent to you.

Take a look here: http://forum.xda-developers.com/xperia-z5/general/guide-sony-xperia-z5-unlock-root-tweaks-t3298224
Bootloader unlock is under # STEP 1 - GENERAL GUIDE
I hope this will help

Also check if you're bootloader is allowed to be unlocked.

Type in dialer *#*#7378423#*#* (*#*#SERVICE#*#*)
Service info > configuration > rooting status.
If it says bootloader unlock allowed :YES you can unlock it, if it says NO u can't unlock it.
If it says rooted or unlocked, you've successfully unlocked it already.

UM, I have E6633 and everything works fine... I used flashtool to unlock bootloader.

Carrier lock, unfortunately as far as I know since the very first Z series impossible to unlock unless u contact the carrier and they unlock it for u.
Keep in mind that they might charge u for that.

[Q] Sony Xperia S Bootloader Unlocking

For people like me who can't unlock their bootloader on the Sony Xperia S because the bootloader unlock option is set to no i.e. the official method below shows no:-
Open the dialer from your device and dial “*#*#7378423#*#*”.
Then, go to “Service info -> Configuration -> Rooting Status”. If the “Bootloader unlock allowed” option is there is perfect and you can complete the operation. If not, or if the status is missing, your device cannot be unlocked.
Is there another way to unlock the bootloader at all?
I realise this will invalidate any warranty but would really like to flash cyanogenmod 9.1 onto it as its so much faster and usable than the stock rom.
Many thanks in advance
Also looking for a way around this... Although my nozomi is unlockable, it fails to unlock with every tool out there...

For those whose status says Yes,you can unlock officially from Sony website

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.
http://www.rogers.com/web/support/wireless/unlock/733?setLanguage=en
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.

Unlocking bootloader imposible

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".

So that's it? If the bootloader can't be unlocked officially, I'm stuck on Sony roms forever?
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).

Unlock Bootloader with unlock allowed says NO

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.

I think Android 6 did a good job controlling app permissions. But thats the thing as you mentioned, you cannot try variety of optimizations from community. sigh.
My boootloader unlock status is also NO.
Is there anyway to flash Androplus kernel with own recovery via fastboot flashtool to get recovery and than trough him install super su zip and with that way root Z5?

Unfortunately not only way is change the device to one that says Bootloader unlock allowed YES the only carrier/network I know of that supply devices with unlockable Bootloaders for all there handsets whether payg or contract is three UK+Ireland as they only supply devices that are sim free network unlocked devices like what you would get from Sony store one of the main reasons I'm with them

Response from Nokia on unlocking bootloader

I can't say I am surprised, but I thought I'd ask and see what they say. Here's an email and the response I received.
Me:
Hello, Before I order the 8, I'd like to know if you provide the means / process to unlock the bootloader for your devices. I typically run stock Android, which I know you provide, but occasionally like to run custom ROM's as well. An unlocked bootloader will allow flexibility, and providing the ability to unlock will gain you a following in the modding community. Thanks!
Nokia:
Regarding your inquiry about the bootloader unlock for the Nokia 8, please be informed that we may not provide this information.
Additionally, please note that unlocking the bootloader for the device will void the warranty and we therefore do not recommend it.
If you have any further questions, please do not hesitate to contact us again.
Best regards,
Nokia Mobile Care team
Now, I am really having a hard time coming up with a NEED for the bootloader to be unlocked... unless I need it to flash another region to add bands that aren't available on my device... maybe?

If you want to root it, duuuh. Like installing SuperSU, dude. :silly:

Well, the question specifically was not about root, but about unlocking the bootloader, which entirely different... dude.:silly:
This is so God damn bad news!
Really thinking about selling this phone right now...

I wouldn't jump ship yet. Fact is, it still may be very easy to unlock the bootloader and gain root, as the device is runing bone stock Android. Frankly, there is not much left that I need root for.
For me, however, the 8 presents a specific problem. I live in the US, and the bands that are listed as supported are missing some LTE bands I really need (12 specifically). I am aware that there are ways to enable available bands for some devices, but I think you NEED an unlocked bl to get that done.
Thats likely a deal breaker for me. :crying:

Well we will see about that...
Thanks for reassuring!
Just taught to have a little chat with support too...
Maybe there's still a way to flash TWRP without unlocking the bootloader. They did it for example on the Nokia 6 by booting into what they call 9008 port mode (EDL in other words) and flashed the recovery with a tool named MiFlash in that mode. (Link to Nokia 6 thread)

This is simply ridiculous and not treating the customers serious enough.
Hi all,
i found an option in Developer Options -> OEM unlocking ->allow the bootloader to be unlocked.
To get developer options tap 8 times "Build number" in About Phone section of settings.
I hope this is the right way for unlocking bootloader.

We already know that. Enabling that setting doesn't do anything.
anyone tried unlocking bootloader via fastboot?
before i get flamed for being a noob, yes i know you need to enter a code or something to unlock bootloaders unlike pixel/google phones.
no harm trying right?
Hmm. I know some devices in my past have not required an unlocked bootloader to allow root, but I'm not savvy enougb to figure out if its possible on this device.
And rooting will NOT void warranty in EU.

Hasn't a case like this have already been handled by a court. Consumer was right.

I could only get the 8 into Download mode and could not install it as a FastBoot device.
Sure sucks that they seemingly won't allow this. I was interested in a Nokia phone as well. HMD have even said they want their phones to be like the new Nexus. They really need to support the custom ROM community if so!
Ok so, I can get the device to boot into bootloader(download mode) and somekind of a recovery, trough ADB in windows.
But no luck on "fastboot oem unlock" command. --FAILED <remote : flashing unlock is not allowed

Hi Daniel,
Does unlocking bootloader violates the guarantee/warranty?
I just purchased Nokia 8 5 days ago.
Thanks.

If you are in the EU, no unlocking the bootloader does not void your warranty. It's protect under EU laws. Someone mentioned that in earlier posts. Unless you are in asia or some other parts of the world where they screw consumers in favor of big businesses.
and if you had read through, there is currently no way to unlock the bootloader on the nokia 8. If there was a way and devs are willing to move over to this beautiful device, i'd get it in a heartbeat.
