Single SIM Firmware on Dual SIM device - Sony Xperia XZ Questions & Answers

Hi guys,
I' currently thinking about getting the Xperia XZ.
I'd like to take the Dual SIM version because of the bigger storage. However, I don't need the Dual SIM feature and rather have quicker Firmware updates.
Therefore I'd like to know if I can flash the Firmware from a single SIM XZ to the dual SIM XZ?
Will I still have the 64GB of storage?
Thanks in advance

Flashing a single sim firmware on a dual one can throw your Device in a bootloop, although I've never tried it but I think flashing the wrong modem & baseband can definitely screw up your Device.

Thank you for this answer, although I have hoped for something more positive
Okay, I think I'll refrain from buying this phone then. Hmm...

Sorry to dig up an old thread. Did you end up trying this? I'm curious too.
Cheers

This should work. Remember having done this (actually the reverse) some years ago flashing the Xperia M Dual FW to the single SIM variant because -interestingly- the Android version of the Dual-SIM was higher (believe it was 4.2 vs. 4.1 or something). Anyhow, if it doesn't work, well, just flash the correct one and you're up and running again.

It may work if after flashing the single sim firmware, you use flashtool to flash only modem and baseband from a dual sim firmware.

Has anyone figured out how to do this yet? Is it safe? I want to flash a Single-Sim variant on to my Dual-Sim XZ as well, but I can't find any guide/tutorial on how to do it and also how to get the correct modem and baseband files.
Can anyone assist with a quick guide?

[DEV] - A call for all devs: help to add dual SIM support on ROMs

I know that the Moto G is a recent phone, and because of this, we don't have much devs working on ROMs or something. But I follow all topics on the Android Development section and I observed one thing: almost nothing released yet (like alternative ROMs or the US update to Kit Kat) is compatible with the dual SIM variant of the phone.
I know that this variation won't be sold in a lot of markets, but here in Brazil, we almost encounter only the dual SIM version on the local and online stores. 'Cause here, dual SIM phones are really popular and necessary (let's say that our network operators isn't that good).
So, let's talk about what cares: I'm here to request to you guys to support the dual SIM on your ROMs. I know that is easy to do a request like these... so, I'm here to help and test together with the devs. I think it's important to develop a way to include the Dual SIM support on the future ROMs. So, everyone with a Moto G will be able to install the ROMs, independent of the variant of your phone.
My phone is a brazilian XT1033 16GB Dual Sim, with stock Android 4.3, unlocked bootloader, root and ClockworkMod Recovery running fine.
I installed the Infusion ROM, the Kit Kat repack and the Kit Kat US Stock ROM (yeah, I'm hungry for Kit Kat) and the results are the same: only one SIM are showed on the notification bar and we can't get any signal from the operator. Otherwise, everything works fine: wifi, apps, the general system...
You guys can ask me anything about the phone or give me instructions to extract certain files from system that you need or commands on adb/fastboot to get details of this variant. Remember: I'm here to help. :good:

I believe that for KitKat you'll have to wait for Motorola Brazil to release the update.
OP, can you pull me some things from the stock brazil 4.3 rom?
i need
system/vendor/lib/libril-qc-qmi-1.so
system/lib/libreference-ril.so
also what happens when you flash the GSM US 4.4 factory image ? does data still not work?

Of course! Attached to my reply.
When I flash the 4.4 factory image, I get the same issue: one SIM showed on the notification bar, without data/signal.

I've also got the very same model as well, initionally I thought like oh ok imma just flash 4.4 US retail with modem files from stock Brazilian firmware but what seem pretty straightforward turned out the total opposite way when it comes to carrier signal. Do those files you requested have anything to do with radio?
I am on "Oi" and it's based on GSM network.
actually i need a few more

You know what?
It's better if you have access to the entire system folder so there it is.

The problem with dual sim is that today Android does not support dual sim! Each Dual sim phone use a propriatary software to use dual sim. Maybe we can"hack" the software in order to make your phone a singlesim, but it will be very difficult to support dualsim phones... For your information, CyanogenMod does not support any dual sim phone...
Sorry...

THAT is more a result of most dual SIM phones being based on MTK SOCs for which no sources are available (similar story for other Chinese SOCs, BTW, but MTK is the worst offender)...
Dual sim support isn't critical, I suppose most of Dualsim owners would be happy with at least one sim working properly.

Considering that the new Motorola is more "open" and friendly for the devs now, maybe we can ask they for release the dual sim specific sources...

No way. If someone buys a dual sim phone, It's supposed to have both working fine.
Like I said, to me is totally indispensable: I have one SIM from a local operator, to make calls (with this SIM, local calls are REALLY cheap) and another, with a unlimited data plan (that I use on university to connect my laptop to the Internet).
I'm just and simply saying it's better have one than no Simcard working at all I don't know about you but I'm looking foreword to get Cyanogenmod and as been said before there's no dualSim sources available and highly doubt there will ever be.
Well I only using 1 Sim right now, but my mom bought me the dual SIM, she didn't even think about that, and I think is the only only she founds.
If at least one works, is definitely better then no one working, like KitKat is right now for me.
can you post output of thi command
adb shell

[Q] Dual SIM ROM in Single SIM Phone?/ SIM Not recognized

So Ive been trying this for such a long time its disgusting. The thread title is my own conclusion from my research throughout the web but I may be wrong in my conclusions.
I have a Huawei G510 since last year. As soon as I got it I rooted it and found a ROM for it. The ROM is a dual SIM ROM and I remember doing something related to a cust folder or something, but I'm not sure. Fast forward to the last few weeks, I want to update to 4.4, and I download a bunch of roms, all of them work except for 1 thing: They dont recognize my SIM Card. I go to Status in the settings and everything about the SIM is "Unknown".
I found a Lewa ROM based on JB and that one was by chance a dual SIM ROM, and guess what, its the only ROM that works. So thats how I concluded that installing a dual SIM Rom must have changed something so that it doesnt recognize my SIM anymore?
So what should I do? Thanks in advance!:good:
anyone? any help is appreciated

Install firmware to unlock dual SIM feature

Hi,
I just got the Huawei Mate 10 Pro and expected the dual SIM feature. But the phone I received was from operator and it was the BLA-09 model, which supports only single SIM.
Can I get the firmware for the BLA-29 model which supports both SIMs and install it without root or voiding the warranty? I am pretty experienced with Android on developer level, but I've never tried something like this before. I appreciate any help, thank you.

930FD Dual Sim Network Lock

Hi, my phone is currently locked to carrier smart. Before flashing my first rom, as long as I had 1 smart sim card on any sim slot, the other one can read any other carrier. After flashing rom, if I insert 1 smart sim and another one from a different carrier, I get the network lock notification. It works fine though if I just use 1 smart sim only, or smart sim for both sim slots.
Any ideas on how to revert this? Or are there any unlocking apps I can try for free? Thanks!
Got that same phone few days ago, and as far as my knowledge goes the F and FD version shouldn't be network locked as they ship world wide (international model with exynos chip). From what you saying, its after you flashed the ROM you got the second card locked, so my first question would be what ROM have you installed ? and can you link me to it. 2nd idea or question.. Did you flash the FD ROM or the F one? the F is a single sim version, it does have the second slot in there actually but its disabled or locked, so it might be that the 2nd slot is disabled or something. 3rd, have you tried other ROMs ? or even stock firmware, you can confirm if the ROM is the issue.
And my advice is to not try the apps, most of them are either outdated that only work with exploits in old android versions, or a complete scam. Waiting for your reply.
Hi Salazar, thanks for answering! I already forgot what rom it was - that was about 6 months ago. I remember then I had a backup of my EFS and baseband using TWRP. I remember restoring those when I first encountered the problem - that's how I got my 2nd sim slot working again. Problem is I've already lost that backup, and when i reformatted my phone yesterday, the 2nd sim slot wouldnt work anymore. Just tried flashing a number of custom and stock roms earlier today - problem still persists. If you happen to have the same device (G930FD) - mind sharing your TWRP backup for baseband and EFS?

Question 2 same device's but one single & another dual (bountyl

Hey everybody today i received 2 op9 both are in le2115 but one was single & another 1 is dual sim

I'll Donate If anyone able to solve this issue (JUST DM ME IF YOU HAVE ANY IDEA ,MUST)
You sure one was not just converted. The dual sim is correct as that's the global model. We're these phones new or used?
Both are new and not converted coz I flashed many time by same rom
