SIM lock on Oreo - Sony Xperia XZ2 Questions & Answers

My XZ2 was locked to the SIM I was using but I had to flash a different firmware to get the Android P Developer Preview to work on it. Now when I rollback to Oreo from Android P my device asks for a SIM unlock code. I have tried many firmwares including branded and non branded but all off them ask for the SIM unlock code if its an Oreo build. Can anyone help me out as I have no idea on what to do to get the SIM to work on Oreo. Its odd as you need the device to be unlocked to install the Developer Preview for Android P in the first place which still flashes fine.

Sim lock is very very different than a bootloader lock. Sim lock is the firmware that you flashed onto your phone not being compatible with your sim card/carrier. When you are flashing the new firmware are you wiping all as well? Dont leave anything behind aka dirty flashing.

What I don't understand is I had to flash a different firmware to install Android P as that requires your phone to be unlocked to any network. Now when I go back to Oreo my phone says it is SIM locked on any firmware I try. What then doesn't make sense is I can still flash the Android P firmware using Xperia Companion with no problems at all which shouldn't be possible if my phone was locked. It is just Oreo that is having these problems and I want to be back on that rather than on the Android P preview but I need my SIM to work.

It just sounds like you're using the incorrect oreo roms..? IDK man. You might be one of just a very small handful to ever even try this P beta and you're our guinea pig.
You might be better off posting this in the Sony Cross development section since there are more phones in the P beta, other phones may be having this problem.

how to flash 139.12.35.ghost_row.nll.en.mx

Hi folks,
I'm kinda new to android world so bare with me please. I got this moto x on ebay which is categorized as Unlocked. I live in the middle east and the phone works just fine except for the mobile network "3G nor LTE". I realized the phone comes from Mexico with software version "139.12.35.ghost_row.nll.en.mx" so, Is there anyway to flash it to some other unlocked carrier in any part of the world and upgrade it to Kitkat? coz it runs Android 4.2.2 . I'm thinking,et maybe by upgrading or shifting to other carrier, mobile network will work.
Is your phone model xt1053 right ? Then, you can install T-mobile 4.4 rom. Using this rom u can use 2g/3g/Lte without any problems and..... no bloatware, good signal etc.
If u want to flash, u need to open ur bootloader first.

Branded phone. on stock 14.2.a.1.136
I have a question, Would my phone Imei number set itself to 000000000 if I flash the kitkat rom for my device? I tried flashing a stock rom on another build number which was unbranded and that resulted in no service, no connection to my sim manufacturer or able to look up the kernel, nothing worked. So please reply to my post. My phone is bound for 12 months and I would really like to flash a custom rom like Cyanogen on my device. Is there a way to do this or do I have to wait for a year?
After searching the xda forums I finally found a way to get my phone service up and running again.
My phone is Sony Xperia z1 build 6903 Stock 14.2.a.1.136. bound to a norwegian phone service named Telenor.
Any help or tips are much appreciated, I would really like to avoid encountering the same problem again it costed me alot of grief and will not continue to flash or do anything regarding my phone until someone would be kind enough to point me towards the how to's. Thank you for reading
The "how to's" are very well sign posted in the general and development threads, they are stickies
No, you will not lose IMEI

you cant use cyanogen rom bcoz it needs a custom kernel, and for you to be able to flash custom kernel you must have an unlocked bootloader..
im not an expert here but i think you cant unlock your bootloader if it is simlocked to your operator
you can only use modified stock rom as mention here by "gregbradley"
so i think you'll have to wait for 12 months for you to flash cyanogen based rom
Sim lock had nothing to do with boot loader unlock. Some Sim locked devices can be unlocked, some Sim free devices can not be unlocked

Well i already have the sim unlock code. so i Will still use the same sim card, but how do warp into the sim unlock mode? I tried setting in another sim card but the phone just asked me to insert the pin for that as well. Then again I would love to unlock my phone and use the same sim card, only difference the phone will be totally mine. So i can flash whatever rom and kernel that suits me. I have been using cyanogen since day one and would love continue to do so.

Your SIM unlock code will not unlock the bootloader, so you will still be unable to flash custom kernels.
Please read what I have said, SIM unlock has nothing to do with Bootloader unlock.
It is true most branded phones have bootloaders which cannot be unlocked and most SIM free phones canbe unlocked. But that is not an exclusive rule.
If you cannot unlock it now, entering a SIM unlock code will NOT unlock your bootloader.
To enter your SIM unlock code, contact your provider who would have given it to you.

You may want to not show your IMEI number to the world.
You can now goto the Sony website and unlock your bootloader using the official way. You can do this whilst you are still SIM locked, proving my point that SIM lock has nothing to do with bootloader unlock
What possible harm can be done with my imei number? Well sim lock certainly voids the service connection flashing builds earlier than 290.

That's not the SIM lock that does that. It does it on my phone and its SIM free.

I deleted the post, now final question deleting the sim lock literally will then not unlock my bootloader, that I am able to do as of now. But Completely deleting the sim lock will then leave my phone at my disposal, right? Since I have the sim unlock code, but I need to know how to remove the sim lock from my phone, cause using another sim card, which is not from the same company does not jump start the unlock mode.
Tell me if I got everything right. when I insert the sim unlock the sim lock will be completely gone from my phone right? regardless of what kernel or rom I use? and it can never come back?

Yes, just ask the provider of the sim unlock code how to enter it. It should be your network provider. SIM locks or restrictiosn are nothing to do with firmware, android versions or kernels.
Your bootloader can be unlocked now by visiting the official sony website.
Please do not confuse bootloader and sim lock. they are two different issues and you keep talking as if they are related.

Help unlocking G920T to Metro PCS.

Hi guys, I have been reading for days but can't seem to find a concise guide. I am trying to use a Metro PCS SIM card in a locked TMobile S6.
I have installed twrp and root through Odin, but I can't manage to download the G920T1 firmware anywhere without it failing and forcing me to pay. I have tried sammobile and others.
After I flash the G920t1 firmware will his metro SIM card just work or do I then have to do a SIM unlock as well? Do I use a TMobile or MetroPCS unlock code if I need to SIM unlock?
Also does anyone know of a ROM that will allow me to use his Metro SIM without any of the above nonsense? I downloaded a ROM but I only have my Verizon SIM to test and it asked for an unlock code.
Any help is appreciated. Thanks in advance!
EDIT: After checking Android file host I found a link to the latest G920t1 firmware. Downloading now in hopes this gets me one step closer. https://www.androidfilehost.com/?fid=24591000424951428
Well I got the Metro PCS software running fine and when following this guide on unlockbase it says I just need this TMobile/MetroPCS unlock code and to put in the new SIM card and it should work.
https://blog.unlockbase.com/unlock-samsung-galaxy-s6-tmobile-usa/
https://www.unlockbase.com/service.php?id=775
Will report back later this week after purchasing the unlock code and attempting to input it.
One other note is when booting to stock recovery it warms me of multi csc. Its my understanding that this interferes with OTA updates. Is there anyway to fix the multi csc so my friend can take the metro pcs OTA updates or will I have to manually update them for him each time a new one comes out?

Your best bet is leaving it on tmobile rom.. if it's unlocked it's unlocked the sim will work just fine... just because you're using a different sim doesn't mean you gotta change roms
Leave it on what the device actually is, and let the unlock code make anything work for you
The S6 development is pretty dead and you will only really find updates for ours first, and if it's an original Tmobile device.. keep it on that, it's unlocked to work with anything but you don't have to flash anything specific to it G920T Use tmobile stock rom, unlock it and move on and do your business.. install twrp, get root , maybe a custom kernel and or rom?
If you root and leave stock recovery you're gonna have deep sleep issues, there hasn't been any MAJOR updates in awhile and it's only gonna go slower and slower with our device getting replaced by S7's and Note 7's
Roms will be updated to newer firmware bases, and JUST the bootloader and modem files will be online to quick flash within 2 minutes in odin to be updated then flash a updated rom base to the newer firmware if any future releases come.
Don't know too much about CSC sorry about that, but hopefully I at least get you on the right track?
The phone is locked. TMobile has the SIM unlock from the dialer disabled on the s6 firmware. You have to go through them to get it unlocked which my friend is currently unable to do, due to issues with payment on his account. I checked his imei and it says it's all good so I assume a traditional SIM unlock using the Metro pcs software should work.
I wasn't going to root or install twrp as this friend has no need for either and is fine staying on the stock software.

Bootloader & Sims Unlocked Stock AT&T 4.4.X Moto X, precaution to take for update ?

Bootloader & Sims Unlocked Stock AT&T 4.4.X Moto X, precaution to take for update ?
Hi, i got this AT&T Moto X (Ghost) running stock 4.4.X with already unlocked bootloader and sim unlocked from ebay year ago. The one was starting to be very energy unefficiant, battery was not lasting while in sleep mode for all the day. Ordered a new battery and my step father allowed me to change the roms. So i plan to install mokee 5.1.1 because it would be use with car bluetooth for call.
My question's the following, i used titanium backup to freeze update year ago, since mokee 5.1.1 need the 5.1 modem from AT&T, how do i manually update this model ? I live in Canada and the network's Rogers, so it need to stay sim unlocked and i since i want to change roms, i don't want to lose the bootloader unlock. There's that thread in dev that got all official 5.1 stock roms, if i take the roms and flash it on lastest twrp, do i keep sims & bootloader unlocked ? Thank you.
flashing the stock firmware doesn't effect the bootloader but yes some At&t moto x sim locked after update to lollipop [emoji517]
So safely you have to flash modem (non-hlos.bin) and fsg.mbn
Note : some moto x At&t after relocked will not unlock with official unlock code then you have to use unlocking tools
So be careful

Do you means i cannot update the modem without losing the sims unlock ? ATM, i only plan to flash an updated modem and a custom roms. The customs roms i want to use require the new modem for lolipop. I have been using the search function on xda for hour and doing search on google without anybody saying anything about flashing new modem for AT&T Moto X. If the Sims get locked again, how do i unlock my Sims to use in Canada ? Thank you.

If unfortunately your moto x get locked and not accepting any unlocking codes so it doesn't matter there is many paid tools which unlock your phone if you don't have those tools so give it to any software service center tell them that after update it was locked and they will unlock it easily

Ok, which tools can i use to unlock sim for free in the case it get locked back again. I don't want to say to my step father that i fudged the updating process after i did it successfully a lot of time for year.

Do I lose my already carrier unlocked code if I flash to Unlocked Firmware

So this may seem a bit of paranoia I may have but I already got my device unlocked from T-Mobilw but wondering if I flash the Unlocked Firmware (N950U1 from N950U) and then to Android Pie would I lose my carrier unlock that I already got unlocked from T Mobile by doing so. Also would Carrier to Unlock Firmware break the device?

No you won't lose it because it goes on a spot in your phone that doesn't get touched or erased when you change firmware or whatever. And no your device will not break however if you're wanting to try Android Pie there's one for the N950U1 version out now so you don't have to go all the way back to N950U.. Directions are on the forum already.

The carrier unlock is done server side at T-Mobile. Once it's unlocked, it's unlocked. Period.
