Unlocked Bootloader: NO - Xperia Z2 Q&A, Help & Troubleshooting

Hi Masters!
I want to use systemless root on my Z2 but my bootloader status says 'no'. Is there a way we can turn 'no' into 'yes' like force it? Or is it possible to use systemless root even if my bootloader is locked with a stock kernel??
Thank you for your answers!

Is your phone carrier-branded?

Yes my phone is locked to a carrier? I called them to request an unlock but they refer me to a local technician to unlock. But I don't want to spend just to get it carrier-unlocked. Hopefully there is a way for me to do it on my own.

Sorrily, as of now, there is none... Spending for an unlock code would only get you carrier-unlocked...

stupid question

I have the Mini Pro and I just looked in the service menu and found "Bootloader Unlock Allowed: No" . Now I haven't unlocked it myself, I have only flashed the global official software. Does this mean my phone will accept custom kernels or will it brick if I try?
Thanks
First of all there isnt such thing as a stupid question. Its only easier to answer. You cannot access fastboot without unlocking the bootloader, and you cant install a custom kernel without fastboot. You need to unlock it.
thanks for your reply.
OK so fastboot is needed to flash custom kernel. got that. But even though it says "Bootloader Unlock Enabled:No" I am still able to unlock it and enable fastboot correct?
Thanks
Yes, you have to use a 3rd party app. Cant remember the name, do some research. Its somewhere in the Development for our devices.

says: If you see Bootloader Unlock Allowed: No that means bootloaders are already unlocked
What? No dude... When it says NO it means the bootloader is carrier locked...

This is what made me ask the question. But after looking on here http://unlockbootloader.sonyericsson.com/instructions
it says "2.In your phone, 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."
which made me suspect that I may not be able to unlock it whatsoever
have you bought your phone through carrier? its on contract? if yes, then sorry you cant unlock its bootloader
YES YOU CAN! But you have to pay... Or i think its for free now. Stop talking without doing some basic research first.

There. You can unlock your device by paying. THIS IS NOT AN ADVERTISMENT IT IS SIMPLY TO STOP THESE DAMN POSTS REGARDING BOOTLOADER UNLOCKING.

why are you yelling at us? keep respect, i was assuming that he knows about carrier unlocking.
I am not yelling at you. I am just sick and tired of hearing this crap about Unlocked Bootloader: No and how to solve it.

Unlocking bootloader from Live with Walkman

I researched about the matter, and reached some conclusions:
- I don't want to use the TEST POINTER method, I really don't care about OTA updates or Track ID app (as far as I know there are no more consequences), Shazam and Soundhound do the same
- I would like to unlock the bootloader in some manner that, if I need to relock the warranty will still be valid (same goes for root, but I guess flashing an original firmware unroots the device)
That said, found the official instructions to unlock the BL, but still have the main question: is it the procedure completely reversible? Also, is it free?
Thanks in advance. Also really appreciate if someone corrects something wrong I said.

you can still relock your bootloader and receive official sony updates, but the problem is, you loose DRM(in which if sony finds out, you still lose warranty).
i found this thread and said that DRM cannot be restored :/
I don't know about non free relocking if it will be able to restore DRM though.
oh and by the way, this thread provides the easiest way to unlock and relock your bootloader for free.
goodluck and enjoy
DRM cannot be restored at all.
Install TrackID from market and it will work.
Bootloader can be relocked, doesn't matter how you unlocked.
And yes, it is free.

Ok, so I suppose the DRM Keys only affect the OTA updates (how should we care if we are unlocking BL for custom ROMs
So, I suppose if I have a problem on my Live (but it still turns on), I apply an OFW and then relock it, it's a matter of luck if the techical assistance is going to check if the DRM is still valid or not.
What method do you advice to unlock the BL?

Method, pick which is better for you. I used official method, no messing with cables.

Unlock it the way you prefer to it does not matter it will lose warranty any way it is just luck if they will check it or not at the service center. Any way it is really hard to completely brick your phone unless you don't know what you are doing. The main difference is with the test point method you are able to update using seus without problems and it looks more complicated than it really is I only used a clip
just a question about unlocking thru official method.
since you would have to get the unlock key directly from Sony.
would they be able to track your phone since you will be giving them some details like your name, IMEI, email etc. to get the unlock code?
do the service centers have access to that database?
There are no Sony Mobile Service Centers, phones need to be taken back to shop and they use service of specific mobile repair shop.
Depending on what reason you need to take it back, they might want to check it or not. No one has so far done this, so we have no information.
What is DRM and Track ID ?
I want to unlock bootloader my phone, but I am still confused, what is the risk of a official bootloader from sony ? What is DRM and Track ID ? what is its usefulness for wt19i?
sorry my english is not good

There is no risk either way the difference is that with the official method you will lose your drm (Digital rights management) and the official support of track id (the app from se that you use to search for the info of a song playing in the radio or the tv etc.) meanwhile using the test point method you will not lose them. If you want to install a custom rom like cm9 or miui you need to unlock your bootloader to be able to flash the custom kernels those roms need.
can you save DRM with CWM backup before unlocking bootloader?

Thanks in advance for all helpfull answers.
I just want to understand the following. Some Live's come with "unlock bootloader allowed"="no" others ="yes". What does that means and more important: what are the implications?
I cannot understand the difference because as fair as I understand right now, all live's (branded/sim unlocked or not) are unlockable (referring to bootloader).

When they come with boot loader unlock : no it is a branded sim locked phone in which case you can unlock bootloader but you will have no access to fastboot meaning you are unable to flash a custom kernel, also there will be no way you can officially unlock the bootloader so will have to use the test point method and of course you will need to pay to fully unlock your phone to be able to access fastboot and flash custom kernels.
Did I miss something??

So, for sim locked branded phones ("no")
- To unlock the bootloader: test point method
- Access fastboot: use (and pay) through wotan server
Am I right? I never though that was two different problems.

I'm not really sure about Wotan server however I'm pretty sure about setool and omnius and if you are willing to pay the phone will be fully unlocked (bootloader, sim and fastboot) with one procedure using the test point method.

So, I'm curious, if I have branded sim lock Live ("no" bootloader) can I install an original firmware without using an official channel? Do I need fastboot access?
I'm asking because I'm almost sure that my carrier will not update the Live to 4.0, so I suppose I have to use some other tool in order to install it.

you can debrand (install a generic firmware) your phone using wotan server for free and as i know it will also change your product code so next time and official sony update is available your phone will get it.
thancks! its helps...

[Q] simplist way to unlock bootloader & root

my brother want me to install a new os for him however he is still on stock kernel and os ect 2.3.4 I believe,
what is the simplest, fastest and safes way to unlock the bootloader of his phone,
furthermore can I use flashtool to root his phone and install other kernals ect,
I have tried *#*#7378423#*#* and it says ''yes'' [as his phone is sim unlocked but I know that he has not unlocked the bootloader himself]
thank you for your time and help in advance :good:
The simplist way to unlock bootloader is the official way.. but you will lose warranty and DRM keys.

bootloader unlock allowed: No

hi! is there any way to unlock my bootloader even if the rooting status bootloader unlock allowed says no...? thanks in advance...
Simple answer: no. If it's a must-have, go return it and buy one off-contract.
It is possible that in the future, someone will find an exploit to unlock the bootloader, or at the very least, do something similar to Loki on the Galaxy S4 (get custom ROMs/etc without an unlocked bootloader).
Sure sucks.

I bought one Factory Unlocked without ever being on a contract and it also tells me no, so it looks like it's not possible to unlock the boot loader on any American model.

Confusing thread, but please read the existing threads on this topic as there are a few.
You need to SIM unlock the phone before you can unlock its bootloader.
If you have the T-Mobile variant, check this thread to see if they can SIM unlock your phone:
[CLOSED][T-Mobile USA] Free SIM Unlocking Service - [OnePlus/Samsung/Google/LG/Moto]
Hello XDA, I am back at it again with the free T-Mobile network unlocks. Yep, you heard that right... 100% FREE. This service will allow you to go into your Settings and perform a network unlock. I've been doing this for over 3 years now with...

Run the adb "debloater" script here if you have a T-Mobile device:
Found a chink in the armor... Just enabled OEM unlocking after 11 update...
I haven't got a lot of time to get this out before heading out on a job, so here's the nitty gritty. A few days ago I flashed over "OnePlus_Nord_N10_5G_Metro_by_T-Mobile_OxygenOS_10.5.8" to get a clean start. I then allowed 10.5.14 to install...
forum.xda-developers.com
No need to reboot, once you finish that, going into Developer options should allow you to set OEM Unlocking to whatever you want. Easy peasy.
If it is from T-Mobile, you'll need to go into bootloader to get the serial, unlock code, and IMEI to submit a ticket to Oneplus for an Unlock Token and then wait a week to get it.
You can skip all of that if it's direct from OnePlus - just toggle OEM unlocking in developer options then go into bootloader mode and 'fastboot oem unlock'.
