[Q] Xperia J is possible to unlock BL with test point method??

Hi,
I did research using uncle google but I can't find any good answer.
So the question is: Is possible to unlock boot loader with any other method than official sony web site?
I'm interested if it's even test point method because on my J "Bootloader unlock Status" says No.
Maybe I should flash something jet like simlock.sin?
Any ideas?
Phone was sim locked before but it is already (sim) unlocked by code, unfortunately status remain the same.
Can anyone help with that?

It's impossible to unlock...

Is it simlocked? If it's simlocked to some network you are unable to unlock the bootloader. If you unlock the phone, you will be able to unlock the bootloader

I had several phones that were sim locked and I was unable to unlock the bootloader. After sim unlocking them I was able to unlock the bootloader. The same goes for the Xperia M2, it was locked on T-Mobile MK, after unlocking the phone I was able to unlock the bootloader.

So, I assume that if I flash a debranded firmware from Xperia M2 (My cellphone can't unlock Bootloader about the "[x]Newtork 10" is locked in SimLock) may unlock the bootloader without any troubles? Is that so? Or I'm mistaken?
If I'm correct, that'd be amazing, I'd like use other ways to personalize my phone but I can't 'cause of the stupid Bootloader xDD.
Thanks!

Debranding basically removes all the bloatware that slow your phone down. You can't sim unlock with debranding, only with special code provided by some other sim unlock sites/ebay

Exactly that. Try to enter it correctly because there is a limit on how many times you can enter to network unlock code. If it doesn't work on KitKat, downgrade it to 4.3 and enter the code. I had similar problem where I was unable to unlock on KK but on 4.3 worked fine.

Well, about that, I have a "plan", or, better said, a contract between the carrier and the cellphone, so, I must wait for two days to complete the "legal" contract. So, after that, I guess that I can unlock the device and then, unlock bootloader.
Thanks for everything!

Sony Xperia XZ Premium network unlock

Hi guys! I have the phone from ee uk, but its locked by the mobile operator, I asked them for code they refuse me, tried with "0000" but was wrong code. I found this thread here How to tottaly unlock Xperia Z5 premium E6853 Flash and Bypass FRP but can't flash the device when I download the firm and wait for update give me an error "null" . Is it possible with flashing to be able to remove sim lock, or there are any other ways gyus?

There is no way removing SIM LOCK by Flashing. If EE I believe you have to wait after 6 months before requesting Unlocking Code, The other option is to search on eBay for Paid Unlocking.
Also you can't flash other firmware if it not mean for the device. ( You can flash Z5 Firmware to another Z5 but not Z5 Firmware on XZP)

The website above tells all of the stipulations for unlocking your device. These are generally pretty similar across most carriers.

EE will unlock it after it is 6months old. Go for eBay unlock should be around £12. Do not try random codes. You have got only 5 attempts.

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)

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?

[CLOSED] Bootloader Unlock Allowed "No" to "Yes" is now finally possible.

Bootloader Unlock Allowed No to Yes is now finally possible
Discovered by MrCooper95
QUICK STORY OF HOW IT HAPPENED​
For years, members of Xperia users thought that if you had a SIM locked Xperia phone, you would never able to unlock the bootloader even after you get it SIM unlocked, the Bootloader Unlocked Allowed will still remain "No".
​You would have to buy a factory SIM unlocked phone instead.
For a good price, I've bought a used SIM locked Xperia 1 that has been hardlocked ( 0 unlock attempts left )
The previous owner tried to get it SIM unlocked, but the codes he used were incorrect and went over the unlock attempt limit, causing a SIM hard lock. He did not mention this when he put it up for sale.
Anyway, I looked around the internet and the found a program called QUnlock. ( S1 Network Unlock Tool )
The S1 Network Unlock Tool is free to download but you have to pay credit in order to work. About £20 ( you pay via mobile phone repair shop websites ) and then they will email you a username and password for you to connect to the S1 server in the unlock tool.
So I connected the Xperia 1 via flash mode in S1 Network Unlock Tool and it worked. My phone is now SIM unlocked after being hardlocked.
​After booting up the phone. I went into service menu to ensure that it is free from SIM hardlock, the tool worked successfully.
​but I also checked the bootloader status and it changed to "Yes".
I was suprised and amazed at the same time after all these years, we were told that changing the bootloader status No to Yes is impossible, even people told us that a permanent hard locked Xperia phone can never be reset.

QUESTIONS AND ANSWERS​
Q. What is the S1 Unlock Tool and what does it exactly do?
The S1 Network Unlock Tool is used by professional mobile phone repair shops and it has been around for a long time. This tool is created and only works for Xperia phones.
It is also available to be downloaded for anyone who can do it themselves at home with just a USB Cable.
This tool is used primarily to reverse a Xperia phone with a permanent SIM hard lock ( 0 unlock attempts left ) and changes it SIM unlocked.
​It can be used as a normal SIM unlocking service.
​However nobody really knew, that this tool can also change your bootloader status from "No" to "Yes".

Q. Can I use this tool to change my bootloader from No to Yes if my SIM is already unlocked?
So far yes, some members of Xperia users has reported back to confirm that it works.

​
Q. Why are some Xperia phones not allowed to have its bootloader unlocked?
Because it is originally made SIM locked to a Network Provider/Carrier. ( Factory SIM lock )
​Network Providers/Carriers restricts you unlocking your bootloader due to warranty and safety reasons.

Q. Does this tool directly unlock the bootloader?
The tool does not directly unlock the bootloader, it just allows you to get the bootloader unlocked.
You would still need to follow Sony's official procedure of unlocking your bootloader.

IMPORTANT INFORMATION​
You should always back up your Trim Area Partition (TA.img) if your Sony phone has a backup exploit.
After you have unlocked the phone using the tool, a sign file ( backup ) is created in the tool folder.
Don't delete it, keep it incase anything goes wrong. ( See warning below )
WARNING​There are reports from some users encountering a no SIM card service / detection after they have used the tool. It is evidently related ( so far ) with some of the Japanese Xperia models.
Japanese SO Xperia model ( Docomo / SoftBank )
Japanese SOV Xperia model ( KDDI )
If this happens, restore the backup and get your refund or try flashing a custom ROM or another firmware ( only if it's safe to do so for Japanese Xperia models )

DISCLAIMER​
I will not be responsible for any actions that you make. I am informing you that the S1 Network Unlock Tool can have consequences as it is not fully documented yet.
Please reply back with your Xperia and its model number if you have successfully unlocked your bootloader.
I will keep the thread updated, best of luck.

Interesting info, thanks for sharing. I always thought only sony could change bootloader status from unlock allowed: No to yes

Asking
Where can I buy the credit for S1tool and download the latest version S1 Tool?
I'd bought a xperia xz and found it needs to be unlocked by the tool to turn bootloader unlock allowed yes

Yes where to buy the credit?

Great news and glad to help you out, I wasn't so sure if this tool will only work on a SIM locked phone to unlock the bootloader. But you confirmed that it works in SIM unlocked state, so that's some good news.

hi, any idea this will work on Docomo Xperia XZ / AU Xperia X Performance ? And did you paid 23 pounds to unlock a device ?

I did pay. You can download the software anytime, however you need a valid username and password to start the process. That's what you buy from the website. Got the the information within 24 hours. Windows thinks it's virus. It's not. Just temporarily disable defender for the download folder
As for whether or not it will work for your device:.I think it would. At least that's the impression I got when I emailed customer support. No guarantees from me, however :laugh:

Xperia Z5 bootloader status no to yes
I have got a new Xperia Z5 SOV32 a few month ago. It was SIM unlocked but bootloader status was "no". Finding this thread I have bought qunlock tool from nugsm site, Then tried it to make bootloader status no to yes. After successful work done I have checked bootloader status converted to "Yes". Now I am using Lineage OS on my Xpeia Z5. Totally amazing.......

Nice. THanks

But can you unlock the bootloader after it change from "no" to "yes" ?

I've got the Japanese model of the Xperia X Compact, with bootloader set to "No" in the service menu. Your method totally worked, after buying the item you linked I was able to unlock the phone using the S1 tool. Bootloader unlocked now shows "Yes". Thanks!

Okay so after bootloader unlock says yes is it still unlockable though someone tried? I have been out of game though I have unlocked a few Xperia Z devices in past and as I recall the method was to enter your IMEI on official bootloader unlock page and they were to send you a code or smth for adb might be mixing up because I think my LG's had same method so my question is after entering imei on sony site they allow it automatically?
