Hello
I currently own an Xperia Live with walkman which I upgraded to 4.0.4 ICS and rooted.
I'm interested on using custom ROMs so I need to unlock the phone's bootloader in order to install custom kernels.
In the service menu of the phone, rooting status says:
Bootloader unlock allowed: NO
I've read on other threads that this means that the phone also has a network lock, so even if I use the test point method to unlock, I won't be able to use fastboot mode.
However on the SIMLOCK menu of the service menu, all locks are disabled (And I confirmed it by installing another sim from a different phone company).
¿How can I unlock the bootloader (for free, hopefully), and will it work on fastboot mode?
I would advise you to try and go to fastmode connecting the phone to the computer while off and holding the volume up key, the notification led should turn on blue that means that you will have no problem flashing custom kernels but you will need to unlock the bootloader using the test point method.
Also you can double check if the boot loader is really locked in the service menu, software info, under the s1 Boot Version you will find something like this: 1241-3656 r9A029 the letter "r" here refers to the state of the bootloader the lower case means it's unlock meanwhile the capital "R" means its locked.

He can't use fastboot, because Bootloader Unlock Allowed: No.

So, I will never be able to use fastboot?
Even if I unlock the bootloader through test points or the paid method?
Normally, you'd have to unlock it via Wotan Server. It erases SIM lock and unlocks bootloader. Don't know why your phone is already SIM unlocked, though.
Hi,
I have same problem, Bootloader unlock allowed: NO
On every test point tutorial I saw "if Bootloader unlock allowed: YES, than you can continue doing TP".
I want to unlock it, so I can flash CM9.
Can I still use TP to unlock my bootloader?
No, bootloader cannot be unlocked if fastboot is disabled.
The only way to enable fastboot right now is via paid method, which also uses the test point method. I am not sure, but I have heard that in some cases, that method unlocks the bootloader aswell.
So, no custom ROMs for me
So what's the verdict here?
Even though on my LWW I have Bootloader unlock allowed: NO I did the testpoint method to unlock the bootloader and it passed. Afterwards I have S1 Boot Version: r9A021 (notice the r) which means the bootloader is unlocked AFAIK. However I still have no access to fastboot. I can confirm that the phone is simlocked, and before having to pay to get it simunlocked, I want to make sure that doing so will finally enable fastboot.
Again, will having the phone sim-unlocked enable the bootloader to be unlocked, and more importantly gain access to fastboot?

Yes, the bootloader is unlocked, but fastboot is still disabled and phone SIM-locked. The only way to enable fastboot is via paid method.

That's exactly what I am asking. If the phone gets sim-unlocked, does that mean that fastboot will be enabled? What paid method are you referring to? Sim-unlock code? Or is there some other paid method?
Or to put it in better writing, what paid method is there to enable fastboot?

The paid-method is technically you go to your service provider,and ask them for an unlock code for your phone.Normally,you need to pay,but if you are lucky,they can give an unlock code for free :good:
The method to sim-unlock your phone (based on my reading in this forum ) is insert other SIM card that are different carrier,and turn on your phone.There will be a checkpoint which your phone asking for a code,at that time you insert the code that your service provider gave you,and after you enter the code,your phone will automatically sim-unlocked :highfive:
I'm sorry if some of my information is misleading,I hope someone can fix my mistake (if any though)
Or try this,who knows it might work?

I'm planing to buy an unlock code, just want to make sure that by simunlocking it will enable fastboot.
Only wanted to know if anyone knows that it is certain, because i have no need for simunlock other than enabling fastboot so I can flash kernels

I unlocked the sk17i of my son with another simcard and the code from my provider but... bootloader is still NOT allowed
Have you tried the testpoint method to unlock the bootloader?
Unlocking bootloader and sim unlocking both do separate things, but I'm hoping simunlocking + testpoint method will finally enable fastboot.
I'll purchase a simunlock code and post if that helps with enabling fastboot asap.

That's is called sim unlock,and it is used to unlock the phone to use other sim card provider...it also unlock fastboot in your son's phone
Well,the bootloader still can be unlock,see my previous post

I had the same problem and Unlocked with NO PROBLEM....
I can use Fastboot too...
Ok thanks guys you mean we can unlock bootloader even if it's written "not allowed" on *#*#7378423#*#* after simunlock
I will try it later ... when I can acces to the phone ^^
Now that the tablet z is launching worldwide, what would be the chances of being able to debrand the docomo version of the TZ?
I'm just wondering as I'm not sure how good docomo is at releasing updates.
First we need the SGP321 Firmware.
At the moment there is only the docomo FW available and the WiFi only version.
Maybe someone with a SGP321 device could provide it....

Im with you, I have DoCoMo and I just want to load the stock firmware.
But I found out the bootloader is set to no so cant unlock yet.
Do you know once we get a stock firmware will that unlock the DoCoMo sim lock?

Strange, I got mine from a dealer here in Hong Kong who never mentioned about any unlock and my local sim works in it fine, also xperiax10.awesome said a friend helped him buy his one from japan directly from docomo and didn't have to unlock it either.
some sites do seem to be offered sim unlock but it's rather pricy:

Not sure about others but mine is locked. I can pay $30 to DoCoMo to unock it for me tho.
In my service menu there a X next to network lock so hoping a non DoCoMo firmware will mean an unlock

Really? What locks in the simlock then?
I was reading that the boot loader doesn't contain the sim lock so I assumed it was firmware based.

Yes, SIM-Lock is not dependent on Firmware
This is why you can flash different FW Versions to mobiles/tablets without any problems.
As from my knowledge the SIM-Lock is like a DRM-Key which is stored in the TA (TrimArea).
If you want to unlock your device you have to write the correct unlock code in the dialer, after this with an algorythm the DRM-Key is generated and stored in the TA.
To avoid any problems with SIM-Lock the Flashtool never flashes the simlock.ta file which is in some FTF Files.
The file is skipped

interesting.
If the key is stored in the TA and you unlock your bootloader the TA partition is removed on unlocking of bootloader, people are recommending to backup the TA partition to retain BRAVIA 2..so once you have the backup you could remove the any signs on the sim lock and once you restore it should be unlocked? hah
that's just my thinking....

I think here is an answer from a developer the best solution
You are right in theory, but I think when you remove the signs on the sim-lock the TA is not signed correctly anymore and it will not work. But this is just my thinking...
So for a correct answer we need a real DEV like DooMLooRD or Bin4ry or ....

Yes, Worldgsmcodes.com sent me the unlock code for my SO-03E in 72 hours.
Don't choose Xperia tablet z, choose tablet S, then the support will contact you to give them the IMEI of your XTZ and then they will send you the unlock code.
Works perfectly.
The Unlocking bootloader service sent me a code to unlock the bootloader, ( my XTZ says : Bootloader unlock allowed : No ), i tried this :
In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the phone is correctly connected
Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which u received earlier.
You're device should now be bootloader unlocked
it's not working....

Thanks man, bit the bullet and ordered an unlock code. Hope this works on my docomo tablet z too.
After getting my unlock code, my SIM was already identified.great. Just a quick question, am I stuck with the R (roaming) logo? Im getting 3g signal and 3g working but the logo still stays at R.
Hi guys, I'm on the verge of buying a Xperia Z2 from a friend and he claims he has unlocked the bootloader with the official method from Sony. If this was the case I would not buy it because I obviously want to mod the phone without losing any functionality. So I checked if he really unlocked it: TrackID is working and when I dial *#*#7378423#*#* it says "Bootloader unlock allowed: Yes". Doesn't this mean the bootloader is still locked? And does the X-Reality option for the display only change after a reboot? Because when I switch between "Off" and "X-Reality for mobile" nothing happens.
Last question: It's the D6503 model, Android 4.4.4, Build number 23.0.1.A.0.167. Do I need to downgrade or could I start modding on this basis?
Thanks

It says the bootloader is locked now, it could have been unlocked in the past.
TrackID works on my phone and i have an unlocked bootloader.
To finding if the bootloader has been unlocked and Drm keys lost, go to

It still may have been unlocked, but it would have been relocked through restoration of the DRM keys. But yeah, all the DRM keys are intact and the bootloader is locked.
Hello!
I wrote the following email to Sony Developer World, but they asked me to post it here.I don't know why I should do this because this page is not meintained by Sony. But hoping that Sony will give me a definitive answer I do as they asked me for:
[start of email]
I haven’t understood your risk explanation on your „Unlock your boot loader“ page because to my mind it is a little bit unprecise:
You wrote there:
“Risks
Please be aware that Sony cannot guarantee the full functionality, and will not be responsible, for any unsigned custom ROM being flashed to your device after the boot loader is unlocked. An unsigned custom ROM may not have gone through the thorough tests that we run for each device and software version that we release.
Also, a custom ROM might not work properly on your device, and certain functions and offerings may cease to work. The performance of the device might also be affected, and you may damage your device permanently. In worst case, unlocking the boot loader will cause physical injuries or material damage, for example, due to the device overheating.
Certain pre-loaded content on your device may also be inaccessible due to the removal of DRM security keys. For high-end devices running recent software versions, for instance Xperia Z3, the removal of DRM security keys may affect advanced camera functionality. For example, noise reduction algorithms might be removed, and performance when taking photos in low-light conditions might be affected. The secure user data partition may also become inaccessible, and you will not be able to get any more official software upgrades if you unlock the boot loader.
After unlocking your device, you should not enable My Xperia (found in the settings menu under security on some devices running Android 5.0) as this might cause the device to malfunction.”
I don’t understand the red marked sentence. So my question concerns the removal of the DRM security keys because I haven’t found out who and when they are removed:
WHO removes the DRM security keys? Is it done by SONY when unlocking the bootloader (and why do you do that?) or is it a risk caused by installing custom ROM’s or recovery images?
And what will happen if I’ll unlock the bootloader of my Sony Xperia Z5 compact via the integrated function “OEM unlock”? Will the DRM security keys deleted any way using this or will they be preserved? And will I be able to lock the bootloader again?
Regards
Ansgar

It's done automatically if you unlock the bootloader, i.e. "by Sony".

Most likely, but the DRM keys cannot be restored. They are forever lost.
sorry, that's bull****.
remove the bootloader lock in developer settings and you will see, that Marlin, Widevine and CKB are still active and reported as "key ok"
and no, Sony does not remove them, you do it while flashing.
BTW. there are already early attempts in flashing, and yes they have deleted their DRMs. and no, there is no way to bring them back.
however, for the time being: keep the bootloader closed, as you've no benefits from unlocking it, yet.

Dude, you should relax. There's no manure in my post.
You have misunderstood the toggle in the developer settings menu. It does NOT unlock the bootloader.
The toggle only disables some software features that would cause trouble if you actually choose to unlock the bootloader.
Bootloader in unlocked using fastboot oem unlock, as always.

Well, I'm relaxed, but you help no-one in posting wrong stuff.
Lets make it simple:
Compare it with a simple door and a door guard.
The door guard has order only to let you in, having a specific key.
In order to get this key, e.g. for the z3 family:
Go to Sonys webpage, register, download the key.
procedure for the z5c:
go into developer settings, enable: OEM unlock.
This corresponds to: Tell the guard, no key is required anymore.
Setting the flag of making something accessible is called "unlock" - so: in fact you can call it "unlock the boot loader" by enable the "OEM unlock" in Developer Settings*.
fastboot oem unlock does much more.
In my example:
go to the door,
ask the guard: is door open / already unlocked?
[z3c: handover the key to the guard]
[z3c: Wait to get the "Ok" to pass - guard: unlock the door] -> correspond to: setting flag: accessible = unlock
pushing the door open,
hanging a fat note in the entrance hall telling "Door is open";
So: you did not miss understood what the toggle does, but the whole procedure.
And no: the toggle does not disable some software feature, it just removes the OEM specific key requirement by accessing the boot loader
*Note: I know, that was quite rough simplification, and to be absolute correct: the OEM unlock toggle in Dev. Setting does in fact not physically "unlock" the boot loader. It just removes the requirement for a key in the unlocking process. However, that correspond to an open boot loader, as all attempt to enter it, will not be denied.

I can't argue with you. I'm not even sure where we agree and disagree.
For the sake of other users, here's the clarification:
Under Developer settings, there is a setting called "OEM Unlocking - Allow the bootloader to be unlocked".
This setting does not unlock the bootloader, it just enables the possibility to unlock. That's why it's called "Allow the bootloader to be unlocked".
No DRM keys will be deleted by toggling this setting.
After setting "Allow the bootloader to be unlocked", you can unlock the bootloader using fastboot.
When doing so, the DRM keys will be deleted and the bootloader will be unlocked.
Until you issue the fastboot command, you can't flash any unsigned code - as usual.

We are not arguing here
I asked you to be more specific as unlocking a door does not mean opening it.
However - there is one important thing missing and quite profound error in your summary (beside the "unlock" wording stuff...).
Enabling the "OEM Unlocking" switch bears a high security risk. Unsigned software now can enter the TA.
In fact: you do not have to run the fastboot unlock by yourself. Any piracy software can now make irreparable damages to the phone!

But the reason for the OEM Lock is to ensure, only OEM signed software is able to be installed.
Enabling "OEM Unlocking" removes this check.
This implies:
- Nice people can now provide software to be installed -> custom roms.
- Bad people can now also install software, but to their needs.
To keep it simple: Let some evil person post any rom called "official Sony z5c Android 6.0".
Let this bad person make the appearance of this rom as any official Sony Update.
Users with the OEM lock in place will not be able to install it, as the OEM key from Sony is missing.
Users with the OEM lock removed will install it w/o any burden.
Do not forget:
Original OEM Software still is signed as original software.
To install the original software, you do not have to toggle the "OEM unlock" in the Developers Settings, as this ROM carries the original OEM key.
to install original software, you do not have to fastboot oem unlock
Removing the OEM-key check with the "OEM unlock" switch, makes the OEM-key obsolete. Hence bears a security risk.

OMG dude. Where are you getting this?
You toggle that switch and install an unsigned ROM and I'll eat my shorts.

You either learn this in school, or should find it s.w. in the Android docs.
And instead of flaming you should start reading and learn IT.
So be brave and toggle the switch, which by your interpretation has no meaning.
The rest of the user i can only advice to keep it locked and only enable in order to flash customs Roms.

So, if I get you right, I just need a customized firmware (e. g. a pre-rooted one), toggle that "OEM unlock" switch and install it via recovery mode? And that without loosing DRM keys? If it is so easy rooting is no problem, isn't it?

No, "OEM Unlock" is just a option to allow OEM unlock, so you have to unlock bootloader after enabling it (and you'll loose DRM key)
HI .... I have found the method by which you can unlock your bootloader whit one click.
First check the status of the bootloader you enter the call application and you will be able to * # * # 7378423 # * # *. Unlocking Bootloader Unlocked: yes.
You must have active developer options-in the developer option you will check the usb debug and OEM unlock you will find above, so with that you will be able unlock the bootloader ....
Go to the site: https://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/... there is no support for xperia xz1 but there is support for xperia xz, you will select xperia xz , all you need is the IMEI and the unlock code that you receive the first email, you will receive the correct code because your IMEI it is unique...
Download from the link below SE Bootloader_Unlocking_Relocking, open it, turn off the phone and connect it in Fastboot mode. In this program in the first top box you will enter the IMEI and in the second box you will enter Unlock code ... and press on Unlock BL ... That's all you have to do..

I had a problem with the network and I did not post it when I forgot it appeared five times, the idea is that the rest I deleted, not yet deleted from what I see, that was your problem ????
otherwise I do not understand what you mean. Download the program and use IMEI and unlock code....
I've unlocked my bootloader on my xperia xz1 phone and I've shared it with others ... better let it go...

Let me tell you once again that I posted several times in error
* What do you want to tell me do not understand .....
I cannot access the mega download link.
What is this program used for, anyway?
I mean, what's the advantage of your method to the official one on the Xperia webpage?
PS: I marked your other threads for deletion.
I have removed all the duplicate threads and moved it to general section. Please refrain from going off-topic.

I added a new link to google drive, it's a simple way to unlock, so I unlocked my bootloader and thought to share with others, it seems to me the easiest way to unlock the bootloader, with just one click.....

No way ?

Hello, I'm wondering if someone can answer a slightly n00b question?
I have not unlocked my bootloader since it could be unlocked without messing with DRM and since then I have been relying on methods that can be done with a locked bootloader. I now have an unlockable bootloader and at the point with not being happy with unrooted restrictions.
I am wondering about unlocking and wanted to know all the cons of unlocking these days? With the DRM fix do we actually keep everything?
How about widevine and pictures is all that the same as before?
I have searched but many people say different things and everything is conflicting. Some people say that widevine drops to L3
Thanks in advance
I have a G8342, and in the service menu it says "bootloader unlock allowed: Yes", but in developer settings the "OEM Unlocking" option is greyed out.
Can I do anything about that?
*edit* never mind, I figured it out. It needed to have an internet connection to enable the option, so I enabled wifi. I don't know why they're related.

When I run the ADB command ( fastboot -i 0x0fce oem unlock [unlock code] ) it says "waiting for device." The only screen I see on the bootloader is black with a blue notification LED. The process doesn't work because it never stops waiting. Any solution?
To be fair, I haven't waited in the menu for more than a few minutes. I'll update this message after I've left it for a while.

An Xperia XZ1 Compact. adb devices, adb bootloader all worked. The device is recognized when powered on using such commands.
I tried the fixes for "waiting for device" like USB 2.0, using the official ADB software, and installing the right drivers, and I still run into the same error.
