OEM Unlocking grayed out what to do? - Sony Xperia XZ Premium Questions & Answers

Hi there. I resetted my XZ Premium, because i wanted to use renoroot.
But when I first had this phone (i think for more than a week) I had the same Problem. I could not select OEM Unlock. But before I resetted my Device, I could turn it on or of (make it blue) but now (again) it doesn't want to anymore. Does anybody know, how to get it back Blue ('cause I even setted up WIFI AND inserted my SIM/and used Cellular Data/Mobile Data) and let me unlock it?
I have NO Carrierlock (Carrierfree)
Oh yes BL unlockable and so was OEM unlock
*figured out, that if you have carrierbrand (like docomo or something) you need to flash a firmware that isn't region locked (for docomo maybe the russian, that j4nn posted on here for Dual and Single)
Single is CE (Central Europe, but should work) and Duos is RU (Russian)
Edit:
I just signed up to an gmail/google account and that was it. Now i can toggle OEM unlock.​

[Q] Sim unlock - network unlock

Hi All,
Is the network unlock by flashing modem (http://forum.xda-developers.com/showthread.php?t=2022296) same as sim unlock?
If not how one can unlock the phone having root and bootloader unlocked but not calling my carrier and asking for the code (I've still wait another 4 months to get code from them)? The phone is locked to French SFR.
At the time I've had Neus One, if my memory serves me right, at the time of rooting the phone it was sim unlocked as well.
Thanks in advance for any advise.
p.s. should this thread be placed in different sub-forum, please move it. Thanks.
There are 2 types of unlock:
1) Network unlock = Will allowed your phone the usage of other carriers services, then your own SFR (can use other networks sim cards)
2) Bootloader unlock = Will enable your phone of installing custom or other carriers ROM's
You can root your phone without any type of unlock = Root will enable your phone to install the recovery apps..& others apps (not ROM's)

How can I do network unlock without calling carrier (SFR) and without paying for the code? Can it be done via flashing modem or any other trick?
So far I'm on the binaries provided by SFR, original ICS and then upgraded through OTA to JB.
Thanks.

Where?
Accordingly to the Forum Rules I can't advertise any product or services. Google on line & there are plenty unlock services.
Which version of the phone do you have? The Verizon branded versions **are** SIM unlocked, though they don't work on ATT/TMobile in the US. Furthermore, they don't work with a foreign SIM in the US.
However, if you take the phone abroad and pop a foreign SIM in it, it will work. How do I know this? I'm sitting in Australia on Optus/Australia as we speak...
So, if you have the VZW version, no code is needed.

The law in France changed a few month ago, you just need to wait 3 month and sfr must give you the unlock code. Not 6 month anymore.

Network unlock

My phone's locked to the Vodafone UK network. I've confirmed this by looking in the service menu, SIM Lock and I have a number 5 alongside the Network.
I've flashed the phone with a generic UK rom, but the network lock is still on. I assume the lock setting is somewhere else on the phone ? ie. some partition which is not accessed by a ROM flash ?
Thanks...
to unlock a phone from a network, you need to use a sim unlock key. i don't know about vodafone, but SOMETIMES the carrier will give it to you if you ask... otherwise, pay 20-40 dollars from any site on google for the key and enter it. usually you get the prompt to sim/carrier unlock when you insert a sim card from a different carrier into the phone.
Vodafone UK provide the SIM unlock code for free. I went into a Vodafone shop and asked them to do it when I left them. It was hassle free.
Use this link to get your network unlock code. My code came within a few hours, even though the link says it could take upto 10 days. (In case you have an obscure phone and they have to get in touch with the phones manufacturer)

You'll need to contact Vodafone for a pac code, flashing a customised UK ftf will only remove the bloatware it'll still be locked to the Vodafone network.

A pac code is used to move your phone number to another network, not to make a handset unlocked to any network.
Again, if you are in the UK just call 191 and ask for a simunlock code for your handest or just goto this link

Cheers Greg,
nice one !
I will get in touch with Vodafone.

Unlocking a Japanese Xperia XZ in Australia

I just recently had to move back to Australia after a few years in Japan.
Before I left I spoke to AU (my Japanese provider) about unlocking my Xperia XZ (sov34). They advised me to use their online form, which I did. A follow up call to their help line confirmed the unlock worked.
It didn't.
Back in Australia, when I put an Australian sim card in it tells me "SIM locked by operator - no service" in the notifications bar.
Doing *#*#7378423#*#* reveals this:
The entries read
[] Network 0
[x] Network subset 10
[] Service provider 0
[] Corporate 0
[] SIM 0
Also, putting in an Aussie sim doesn't give me an option at all to enter an unlock code.
Is there anything I can do? I am willing to pay for an unlock code through a trustworthy site, as long as it will actually work. I don't want to pay and find out the phone is impossible to unlock.
So update, I decided to purchase an Unlock code from a site.
Still to recieve it, but I did notice something important.
When I put a new, no AUKddi sim card in the phone, I am given no option to input a code anywhere.
I understand that this is done by some phone companies specifically to make unlocking difficult. I am also of the understanding that I can flash the unlock screen in in some way. Is anyone willing to spare some time to show me how/provide a guide to do so?
sir
1. if your device is SIMLOCKED with Japanese network provider then ofcourse no other sim will work (even in japan). however lets assume that the device is International sim unlocked.
2. in this case if you are using SO3H version of xperia then you must flash AU firmware and try the Sim (suggestion)
3. when you say buying unlock code online... what do u mean? do u mean unlock sim code? or do u mean UNLOCK BOOTLOADER CODE ?
4. please don't unlock your device! unless you first downgrade to Android 6 and EXTRACT DRM KEYS (TA.img) ( its a SAGA if you decide to go that path i will guide you more sir)
5. you can change firmware from japan to AU only by flashtool. ( www.flashtool.net) , sony Xperia Companion may recognise your device as Japan market and flash the same firmware again!
6. please update what is your device mode, and Android version and BUILD NUMBER (sony stockrom)

Well like I mentioned, I used AU/Kddi's online form to unlock the phone, and a follow up call assured me that it was unlocked.

1. Things are much clear now, you were trying to sim UNLOCK the device. if you have succeeded and still cant register AU sim
2. then flashing different market firmware may solve this issue.
3. you should not UNLOCK the BOOTLOADER if you are not interested in rooting the device and
3b. even when you decide that you want to unlock the bootloader then you must first downgrade to android 6 and EXTRACT the TA-xxx-xxx-xxx-xxx.img file known as DRMKEY FILE and then upgrade back to Android 8 and then unlock.
4 sorry, DEVICE modeL . F8331 or F8332 (dual / Single)
Guys, is it hard to check other forum topics of japanese phones?
It's simple - just write with Flashtool a Docomo firmware for this model (all models there have a specific country firmwares list, usually only 3 for Japan - KDDI, Docomo and somethimes Softbank). Usually Docomo immediately asks for code when inserting a foreign sim, it's some KDDI quirk that they removed or broken that function in their firmware with unlocking.
All of this is not related to bootloader - all Sony phones in Japan specifically NEVER ever unlocked on bootloader level, they completely closed their market from "open source" or there's not such strict laws like in EU. So, it's useless to even discuss such with japanese phones.
Update:
I was able succesfully flashing it with Central European firmware (less bloatware than Au) and with foreign SIM it immediately asks for Unlock Code. Only NFC not working, but it's old problem with japanese Xperias (i was able to solve it on Xperia Tablet and only by EU Wifi firmwares, no such for phones and no one tries to extract NFC from there). The problem with japanese firmwares - in Flashtool only Android 6 available, it's not flashing on Oreo phone, showing partition.sin error, so it means also that downgrade impossible. If you want working NFC you need to find japanese Android 8 firmware somewhere (like 41.3.C.1.147 from Au).
Hey, guys... I just wanna ask, what's the meaning of paramaeter at the SIM Lock status.
It say that "[x] Network subset Unlimited"
Does that mean my device it's simlock can be unlock??
Hi, I found this forum as I was looking around for a solution to unlock the bootloader of my Docomo XZ1. Is there anyone that can confirm whether or not its possible to unlock the bootloader in any way?

how to unlock a locked bootloader ! ( oem greyed out )

So i received a american pixel 4 xl with a locked bootloader. imei starting with 35
i was able to unlock the bootloader here is the steps i took, note im in Australia.
Full OTA Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
the firmware on the device was american,
i flashed my countrys firmware (australian) optus/telstra/vodaphone etc
use adb side load *firmware.zip*
factory reset , booted device on with australian sim,
and boom oem was available ,
(last step is to adb reboot bootloader,
and ./fastboot flashing unlock and you will see a message on pixel.
intially with the Original firmware on the device it would not unlock.. i tried factory reset
/ fastboot flashing unlock etc and it would not work...
anyhoo i have not seen anything on here suggested flashing another firmware origin so i thought this might help those with locked at&t / verison carriers, intially it was GREYED OUT AND SAID contact carrier or connect to the internet.
Hope this helps someone ! as all the forums ive swiped thru have said this is not do-able, lol turns out it is.

The firmware does not determine whether the bootloader is unlockable.
When the device connects to the Internet, it checks its IMEI against a whitelist on Google's servers. If it has been authorized for bootloader unlock, OEM Unlocking will become available.
If it doesn't, it's likely that you have a locked variant.

What if it is already unlocked and I want to relock it? I flashed stock firmware, the bootloader is still unlocked but now I can't lock it again because the option is greyed out.

The OEM Unlocking toggle does not lock or unlock the bootloader itself. It simply allows you to unlock the bootloader when enabled.
If you want to relock your bootloader, you do this via ADB while in bootloader mode: fastboot flashing lock

For some reason I couldn't get into fastboot mode, "adb reboot bootloader" would just restart my device. If I booted into recovery, the "reboot into bootloader" option would just start up the phone. But I eventually found out I can lock the bootloader in download mode

Google Unlocked Phone has greyed OEM unlock option

My phone shows unlocked on the official google website, yet the oem unlock option is greyed out. What is the issue with it?
Unlocked probably means Sim unlocked. You need to figure out why it's Grayed out. Samsung uses knox and kg status to block it. From being bootloader unlocked
I don't know if you've read all the other threads....
Which model do you have? If it's Google's "Unlocked" model (the one not made for any particular carrier), you should be able to unlock the bootloader.
I had to connect the Wifi, when I first bought the phone. Until then, the OEM unlock option was greyed & inactive.
