Xperia Z3 D6616 SIM unlock or Custom firmware

hi
i am having my Xperia Z3 D6616 idle for more than 5 months, meaning? its not sim unlocked. actually unable to unlock it. i did not know that t-mob disabled the SIM unlock code pop up in their phones.
i am not in US right now so unable to unlock the phone as i bought from ebay as new. totally fed up with this situation.
i am tried all over the forum and waited log time to get the root, i felt it will be unlocked after then. but unfortunately rooting did not shed any light on unlocking possibility.
so far
1. D6616 cannot be Sim unlocked without Tmob support
2. No custom firmwares.
3. will not boot if international Firmware flashed via flashtool. or flashing pre rooted zips.
4. its known that it the boot loader cannot be unlocked.
i am looking for D6603 firmware ported to D6616 so that we can flash into recovery and get the sim unlock code Pop up to Enter the unlock code.
or anyway how to port the simunlock app from international D6603 FW to make it work on D6616.
I saw and tried HTC one M9 T mob sim unlocking method and it worked on HTC one M9. (the link is below) is it possible can we follow the same method to unlock the D6616 also.
looks like T-Mob disable sim unlock pop up in their phone to restrict the user to unlock as they wish.
link : http://forum.xda-developers.com/one-m9/general/sim-unlock-method-t3143333
i request some developer help how to get this done. i believe they are so generous and helpful. at least some guides on how to make it.

I'm facing the same problem, all servers are down indefinitely. One guy also found if your phone never were used or registered in T-mobile network, can't be registered as elegible to unlock, this is my worst problem, I'm outside of USA with brand new expensive phone . If some one found any other solution to unlock, I'll appreciate the information

Unlock service is up.
Now we can unlock xperia Z3 with t mobile app,
The service is up. I bought the unlock service from cellphoneunlock.net
This service cost 50$, but this is the only option for D6616. Time will 3-6 days. I unlocked two of my D6616 after years

not that I believe in pay for those type of services. but I have a z3v and am in a similar position. I was wondering if you could check if your bootloader unlockable status has changed from no to yes or how can u flash stock z3 firmware with only a sim unlock.

This has nothing to do with the bootloader, it is for unlocking the sim only. The z3v is alread SIM unlocked, but, like the T-Mobile d6616, the bootloader is locked and likely to stay that way.

U.S. S7 [Snapdragon] locked to my previous SIM - how to unlock it for a new SIM?

Hello community,
I´ve searched everywhere to solve this issue without success - I hope you´ll be able to provide a solution.
I´ve bought an unlocked S7 with Qualcomm/Snapdragon in the U.S. (no carrier contract) - I´ve used the phone for about 2 months with a U.S. local SIM card and everything worked fine.
Back at my homecountry I wanted to insert a new SIM from a local german provider but the phone refused to accept it.
Error message: Invalid SIM (please insert the UICC which came with the device) mhhhh, the device didn´t came with any UICC?!?! Looks like a simlock...
In several articles about the S7 I´ve read following e.g. "S7 will lock to a carrier once a SIM card is inserted" .... how can it be? I mean is it true?
So I wanted to root the device but I´ve noticed really quick that the Qualcomm/Snapdragon version has a locked bootloader, means root is not possible at the moment
Simple question
- Is there aaaany way to open/unlock the device to a new SIM carrier?
I just want to use my phone :crying:
Thanks in advance for your support.
Best regards

US phone will not work in the EU, as far as I know. Even if the radios are capable, there are blocks in place via Samsung, FCC anb EU that won't let it happen. Could be wrong, but yeah.

Maybe you can try to activate developers options by pressing on build number in software info 5 times. Under developments options there is an option for OEM unlock, try that.

Hello MattBooth,
yes you did. I just received feedback from Samsung Germany and you are right. There is really a regional lock between US & EU versions.
According support team here in Germany I have to contact the region where the phone was sold.
I will contact the US Samsung support and chek if it is possible to unlock it. I will keep you in the loop.
By the way - I would still prefer a root solution...hope it will not take too long until someone will find a way to root a Snapdragon.
Other solutions are still welcome...go on with the tips :good:

Hello Major7070,
thanks for this very valid comment - I´ve never heard that a CSC can be flashed with a locked bootloader but if it is possible it could solve my issue...maybe at least :fingers-crossed:
@all, does anyone know if a CSC will help me in this case?
This is the current situation:
- Samsung Germany replied to my request following - yes, there is a regional lock in this phone, please contact the support of the origin country.
- Samsung USA replied following - there is nothing like a OEM regional lock in this phone - there is just a carrier lock by Boost Mobile, please get in contact with Boost Mobile
Boost mobile replied - we will help you with the unlock but you have to fulfill 3 requieremts:
1st - you need to be a boost mobile customer or former customer
2nd - the device should not be reported as stolen :good:
3rd - the device need to be at least 12 months old
I failed on requirement no. 1 & 3 - furthermore Samsun GER and USA gave contratict answers.
I didn´t even purchased the phone with a Boost contract - just used a Boost Mobile SIM during the three months.
The issue can not be caused by a carrier Simlock because if it would be created by it the phone would ask for the Network unlock code of each invalid SIM which is inserted to the device BUT it does not.
=> if this would be the case e.g. Unlockbase could help me with the issue but they can´t
OMG...I´m going crazy.
Thank you.
Best regards

I'm interested to hear if you found a solution to this? I have a U.S. S7 and I want to take it to Germany here in a month. I've been trying to get a Sim unlock code here last night but haven't had a success through att. Have you tried purchasing a code from a third party seller?

After all this answers it's seems that your S7 is Sim locked. YOU should try an online service for sim unlock your device. There are several app on play store, about 20 usd for that and a code is usualy provided in hours. At least for europe. All the apps provide full refound if the code is not found. Search for imei unlocker or unlockscope in play store
Good luck!

Hello calinormy,
this were my first thoughts as well - but as I said, the phine is not asking for the "network unlock code".
I was in contact with several unlock providers and they said, that they can´t do anything for me as long as the phone is not requesting this code.
@all, I mean I´m willing to pay for such an unlock code...at least it is a try - but is there any way to insert the code via hotkeys if the phone does not request it?
Thanks.
Bye

Have you tried to factory reset the phone with the original sim inserted and then once complete insert the local EU sim? You might have to get a T-mobile USA sim to have the phone request a carrier unlock, not sure why that would matter but it's worth a shot.

SOLVED
Hello all,
just want to inform you guys that the issue with the "Invalid SIM" is solved now - BUT there is a new issue.
FYI
I had to downgrade my device with the stock ROM (see software Version)
Baseband was G930PVPU2APE1 => and after downgrade G930PVPU2APC5
The unlock was done by Samsung unlock remote client from 123unlock.nl

I have a new issue now:
The device does not connect to a network operator by itself and furthermore the option "Network operator" is not available in the settings (see attached pictures)
Any idea how to solve this problem or should I open a new topic?
Thanks.

What does it show your imei as?
Sent from my SM-G920T using XDA-Developers mobile app

My guess is that you will have to upgrade to the latest ROM you already had installed. It might be that the IMEI cannot be read since that was upgraded with the ROM (and a downgrade of that partition will never happen)

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".

Click to collapse
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.
Click to expand...
Click to collapse
​
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.

Click to collapse
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?

So I've curiously checked the bootloader status and surprised to find out it has changed No to Yes.
It still amazes me because all these years, we were told that it was a permanent status. Sony website so called helpers are absolutely useless and clueless.

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.

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:

Yes it should work on those devices, the tool supports devices from 2013.

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?

@betacrypt
Can you provide a copy of the software? Have an XZs I would like to fully unlock as it is already network unlocked. Please post on Gdrive or Mega if you can.

I've bought an network locked Xperia 1 on ebay after getting the Xperia 5 and found out that it was hardlocked (0 unlock attempts left).
So I've looked around the internet to find a solution and the solution is called QUnlock (S1 Network Unlock tool)
Getting the software program is free but you have to pay credit in order to work. About £20 (You pay via mobile phone repair shop websites) then they will give you username and password to connect to the S1 server.
So I did that, connect my phone into flash mode and boom my Xperia 1 is network unlocked after it's been hardlocked.
So I've curiously checked the bootloader status and surprised to find out it has changed No to Yes.
It still amazes me because all these years, we were told that it was a permanent status. Sony website so called helpers are absolutely useless and clueless.

Is it possible to convert from SOG02 to XQ-AS42?

As we all know SOG02 doesn't have a unlockable bootloader but XQ-AS42 is a sim unlock device which is also a japanese version if i flash that on my will the sim card stop working??

Hi,
I have succesfully unlocked the bootloader on SOG02 that I bought cheap, 200USD.
It had allow bootloader unlock: NO.
after running sim unlock with S1 tool qunlock it said allow bootloader unlock: YES.
then I unlocked bootloader via ADB Tools the normal way and installed LOS 20.
Funny thing is, that under LOS (I didnt check under stock FW what it says, probably same) it now reports as
model XQ-AS72 (Dual SIM) (Asia outside Japan)
Even though it clearly isnt dual sim but single sim...I think the unlock tool tricked it into being another model, hence allowing unlock.
hope it helps you
After running the qunlock, sim card was not recognized, so then I restore the backup of qunlock and everything is working after that (bootloader stays unlocked).

Do i have to pay for it? Is there any way that i can unlock it for free?

yes you have to pay. considering you pay a fraction of a price for this kind of locked down phone, it's still a big discount. 200USD + 30USD is still cheaper then 700USD that this thing still costs on amazon for some reason!
But if you paid the full price for a japanese carrier locked phone then you got screwed over, sorry.
In my case, LIneageOS is a must because I dont use google services for years now. If the phone cannot run LOS, i cannot use it, i would just give it away or sell it if there was no way to unlock it

What you have to do is unlock the bootloader before restoring the backup. This way you can unlock bootloader and use sim cards.

I have this SOG02 version as well, I'm on android 12. Did you notice any improvement in network quality once you swithched over to LOS 20? I like the deivce but the network issues are definitely very annoying

Hi, I never used it on android 12. it had some japanese apps and overall I dont like google and I don't like stock bloatware, so I immediately flashed it with LOS. in the last 10 years all my phones look the same, with same OS (cyanogenmod before lineage) same desktop background and same ringtone, it's like apple user experience on android
What network issues? poor signal strenght when you check the icon? I read somewere its just a software thing, if everything works OK just ignore the signal icon

Mainly poor signal strength. Also I was having trouble with my SIM as it was not detected. I don't remember taking a backup of my SIM with the qUnlock tool. Any way of restoring it?

I spent around 21USD to do this. Running voidUI on my SOG02 right now, A13. I think pretty much everything works. Here's a guide I wrote specifically for this -

i am not sure if this unlocking procedure messed up my signal strength (because I didnt use it with original firmware) or it was like that from the factory, but signal is very bad.
I have no coverage in my basement parking where I had normal coverage with other phones..
